Orangery invoice template UK (2026): roof lantern, CIS and VAT

By InvoiceAdept Editorial · 6 September 2026 · Local preview wrap - not live CMS

An orangery invoice has to explain what was surveyed, founded, walled in brick or stone, roofed with a lantern or insulated flat sections, glazed and finished - not a vague "orangery done" line. "Supply and install orangery as agreed" does not tell a householder whether a rear orangery, side-return orangery, brick-base orangery with roof lantern, lean-to orangery, orangery with bi-fold doors, or orangery kitchen-extension hybrid was included, whether dwarf walls and lantern were in your scope, or whether steels and flat-roof insulation were free-issue. It does not tell a main contractor's QS which plot, purchase order or package to release. It does not tell a CIS contractor how much is labour and how much is the direct cost of brick, stone, steel, roof lantern, insulated flat roof materials, bi-folds, glazing, electrics and underfloor heating you paid for.

An orangery is not a glass-box conservatory. Typically it has brick or stone dwarf walls, more solid wall area, and a larger roof lantern and/or insulated flat roof sections rather than a fully glazed polycarbonate or glass roof. Mentions of a conservatory on this page are contrasts and cross-links only - the subject here is the orangery package.

The payer and the operation both matter. An orangery specialist billing a private householder for work on their own home sends a normal invoice: no CIS. The same firm billing a main contractor, developer or refurbishment principal for construction operations can be inside CIS. HMRC's CISR14100 treats alteration, repair or extension of a building as construction operations (Finance Act 2004 section 74(2)(a)). A contractor-paid orangery alteration or extension usually sits there. When orangery works form part of a wider preparatory or finishing package (scaffold, plastering, insulation as part of the project, integral fittings), CISR14240 is also relevant. Private householders are not CIS contractors - see the public CIS overview.

VAT is separate. If you are VAT-registered, an ordinary orangery on an occupied existing dwelling is usually standard-rated at 20%. Notice 708 reduced (5%) or zero rates only apply when narrow conditions are met - soften absolute claims; check VAT Notice 708 and your VAT adviser. Never reverse-charge a householder. Architect, surveyor and design fees are usually standard-rated even when some construction services on a project are reduced-rated.

This guide gives copy-paste fields, a labour/materials split for orangery packages (including roof lanterns and insulated flat roofs), deposits and stages, four worked examples and a practical treatment of CIS, VAT and domestic reverse charge. Figures are illustrative only, not UK market rates or a price list. InvoiceAdept does not decide CIS or VAT status and does not file CIS300, VAT returns, Making Tax Digital updates or Self Assessment to HMRC. It does not issue Building Control completion certificates, planning permissions or Party Wall awards.

This page focuses on residential orangeries - brick-base with roof lantern, lean-to orangery, side-return orangery, bi-fold packages and orangery kitchen hybrids - not full house extensions without an orangery brief, and not stand-alone garden rooms.

In short

Start by identifying who pays you, what orangery type you supplied or installed, whether the structure sits on foundations with brick or stone dwarf walls, whether a roof lantern and insulated flat roof sections are included, and whether the contract is supply-only or supply-and-install.

Private householder, own-home orangery: no CIS. The householder is not a CIS contractor. If VAT-registered, an ordinary rear orangery / brick-base orangery with roof lantern / side-return orangery at an existing lived-in home is usually 20%. Show survey/design, strip-out, foundations, brick/stone dwarf walls, steel/roof structure, roof lantern supply+fit, insulated flat roof, bi-folds/sliding doors, glazing, electrics, underfloor heating, plastering/skimming, flooring, waste, Building Control fee and snag/retention clearly. Do not claim "VAT free" because it is an orangery or because it has a lantern.

Orangery package for a CIS contractor: typically within CIS when a contractor pays you for alteration or extension works (CISR14100). Cite CISR14240 when works sit inside a wider finishing or preparatory package (scaffold, plastering, insulation as part of the project). Split labour from materials at direct cost (CISR15060 / CISR15090). For a roof lantern or prefabricated roof/glazing package purchased complete, materials are usually the purchase cost; labour is the install.

Manufacture and delivery of materials only (no install): generally outside CIS (CISR14220). A mixed contract that supplies a roof lantern / frame package and includes installation can pull the whole contract into CIS (CISR14020 / CISR14030).

VAT reduced rate (5%) or zero: only when Notice 708 conditions are actually met. Ordinary orangeries on an occupied house stay 20%. Never reverse-charge a householder. Never invent 0% for a normal brick-base orangery with roof lantern.

Take a deposit before ordering brick/stone, steels, the roof lantern, insulated flat-roof materials, bi-folds or glazing if your terms require one. Number and invoice that deposit. Then use recognisable stages: survey / deposit, foundations and dwarf walls, steel and weathertight roof (lantern + flat sections), finishes / electrics / underfloor heating / snag. Keep variations for lantern upgrades, extra bi-folds, kitchen hybrid adds or flooring changes separate from the agreed orangery package.

Use the invoice generator for a first invoice. InvoiceAdept Free is £0 for five invoices per month. Pro is £7.99 excl VAT and includes WhatsApp send. Pro+ is £12.99 excl VAT and includes CIS. Stripe's own fees apply (UK cards 1.5%+20p), but InvoiceAdept adds no platform fee.

Who this orangery invoice template is for

This template is for UK orangery installers, builders who deliver orangery packages as a defined product, glazing firms that supply roof lanterns and bi-folds into orangery builds, and subcontractors who dig foundations, build brick or stone dwarf walls, erect steels, fit lanterns, glaze, wire or finish and need readable invoices for householders, landlords, builders and housing clients. It covers the paperwork pattern, not a price list and not a Building Control or planning document.

  • Orangery specialists (rear, side-return, brick-base with roof lantern, lean-to orangery, bi-fold packages, kitchen hybrids)

  • Builders who include orangeries in residential packages

  • Groundworkers and foundation crews billing orangery footings and slabs

  • Bricklayers and stone masons building dwarf walls and solid wall sections under lantern roofs

  • Steel / roof structure crews and lantern installers

  • Glaziers fitting roof lanterns, side glazing and bi-fold / sliding doors on orangery jobs

  • Electricians and underfloor-heating installers billing as part of an orangery package (or separately)

  • Plasterers, flooring crews and finishers on orangery packages

  • Subcontractors to main contractors on residential orangery packages

  • Sole traders and limited companies who need CIS and VAT lines that match the payer

If your day job is a glass-box conservatory, a small porch, a full house extension without an orangery brief, a stand-alone garden room, or a garage conversion, use those related guides and come back here for orangery-specific lines (dwarf walls, roof lantern, insulated flat roof, more solid wall area).

Three orangery jobs, three invoices

These three jobs can use similar brick bases and lanterns but need different invoice logic.

Domestic householder orangery

Contractor orangery package

Materials-only / supply-only caution

Customer on invoice

Private householder

Builder, developer or specialist principal

Builder, merchant customer or householder

Contract

Survey, foundations, dwarf walls, steel, roof lantern, insulated flat roof, doors, finishes

Orangery package to named plots or addresses

Supply lantern / frame / roof materials delivered; no install

CIS

No. Householder is not a CIS contractor.

Usually within CIS as alteration/extension - CISR14100; CISR14240 if finishing/prep package

Generally outside CIS (CISR14220) - unless mixed with install

Labour/materials

Helpful for clarity

Essential for correct deduction; lantern and flat-roof materials at direct cost

Materials supply lines; no CIS labour block

VAT if registered

Usually 20% at an existing lived-in home

Normal VAT or reverse charge depending on tests

Usually standard-rated supply

Key references

Public CIS guide

CISR14100; CISR14240

CISR14220; CISR14020 / CISR14030 if later install added

What often bounces it

"Orangery done" with no type, lantern, dwarf walls or deposit credit; "VAT free" myth

Missing UTR, plot/PO, labour/material split; claiming free-issue lantern as your materials

Treating supply-only as CIS labour; then adding install under same contract without revisiting mixed rules

A main contractor can be the CIS contractor even when the finished orangery serves a tenant or homeowner. If the builder engages you, your invoice is to that builder. That contractor-to-subcontractor payment is the one to test. If the householder hires and pays you directly, the householder invoice has no CIS.

What orangery work belongs on the invoice

Do not compress a multi-week orangery into "supply and install orangery". Describe survey/design, strip-out, foundations, brick/stone dwarf walls, steel/roof structure, roof lantern, insulated flat roof, openings, services and finishes, and what another firm supplied.

Name the type. A lean-to orangery with brick dwarf walls and a lantern is not the same invoice as a glass-box lean-to conservatory, and an orangery kitchen hybrid is not a pure kitchen fit-out invoice.

What a UK orangery invoice must include

UK invoices need the basics HMRC and customers expect. See GOV.UK invoicing guidance. For VAT-registered traders, VAT invoices need the extra fields in that guidance and your VAT registration number.

Field

Why it matters for orangeries

Your trading name and address

Who to pay and who issued the invoice

Customer name and address

Householder vs contractor identity

Unique invoice number

Deposit, stage and final must not collide

Invoice date and tax point

VAT timing; CIS period reporting

Description of work

Orangery type, foundations, dwarf walls, roof lantern, flat roof, openings

Labour vs materials split

Essential for CIS deduction base; lantern and flat-roof materials at direct cost

CIS details (if applicable)

UTR, verification, rate 20% / 30% / 0% gross

VAT rate and amount (or reverse-charge wording)

Usually 20%; reverse charge only if DRC tests met

Totals due and payment details

Bank details; Stripe link if offered

Deposit credit / variation references

Stops double-billing arguments

VAT registration threshold is £90,000 (see VAT registration). Do not use outdated £85,000 figures as if they were current. Deemed contractor status for CIS turns on construction spend of more than £3 million in the relevant period - never quote £1 million as the current threshold.

Labour versus materials for orangery CIS

For CIS, materials at direct cost can be excluded from the deduction base (CISR15060 / CISR15090). Mark-up is not materials. Free-issue brick, stone, steels, roof lantern or glazing from the contractor are not your materials - note them as free-issue so you do not claim them in the materials exclusion.

For a roof lantern purchased complete, treat the purchase cost of the lantern as materials and the installation as labour. Keep the supplier invoice on file. The same pattern applies to bi-fold doorsets and insulated flat-roof membranes you bought.

CIS deep dive: orangery alteration and finishing packages

Prefer CISR14100 as the primary cite for contractor-paid orangery alteration or extension works (FA04/S74(2)(a)). Digging foundations, building brick or stone dwarf walls, erecting steels, fitting a roof lantern, building an insulated flat roof and weatherproofing abutments are fabric works, not a soft service.

Cite CISR14240 when orangery works sit inside preparatory or finishing operations that bring a wider construction project to completion - for example scaffolding erected for the orangery package, plastering and skimming as part of the finishing package, or fitting thermal insulation as part of a wider project.

CISR14220 generally keeps manufacture and delivery of materials without installation outside CIS. If your contract mixes supply of a roof lantern or frame package with any install, mixed-contract rules can bring the whole payment into CIS - see CISR14020 and CISR14030.

Householder reminder in one line: private domestic orangery invoices should never carry a CIS deduction block.

VAT: ordinary orangery on occupied dwelling versus Notice 708

Keep three buckets clear. Soften absolute claims; your VAT adviser and VAT Notice 708 win over blog wording.

Bucket

Typical treatment if VAT-registered

Honest caution

(a) Ordinary rear / side-return / brick-base orangery with roof lantern on an occupied existing dwelling

Usually 20%

Do not claim VAT-free because "it is an orangery", "it has a lantern", or "it is outdoor living space"

(b) Qualifying residential conversion / empty-home renovation under Notice 708

May be 5% when conditions and evidence are met

Change in number of dwellings; empty 2+ years renovations; non-residential to dwelling - document the facts; an orangery alone rarely creates this

(c) Supply of materials / lantern without installation

Usually standard-rated

Delivery-only lanterns are not an install

Architects, surveyors, designers and consultants are usually standard-rated even when some construction services on the same project are reduced-rated. Do not bundle professional fees into a reduced-rate claim without checking.

Also check Notice 708 for zero-rating on qualifying new dwellings - that is not the normal occupied-home orangery case. An ordinary brick-base orangery with roof lantern on a lived-in semi is not "VAT free". VAT registration threshold remains £90,000.

Domestic reverse charge

Domestic reverse charge may apply when all of these hold: both parties VAT-registered; the supply is construction services reported within CIS; the rate would otherwise be standard or reduced (not zero); and the customer is not an end user. Never reverse-charge a private householder. See InvoiceAdept's domestic reverse charge invoice guide.

Customer

Typical VAT face of invoice

Reverse charge?

Private householder

20% (or reduced only if Notice 708 truly applies)

VAT-registered CIS contractor, standard-rated orangery package

Reverse charge wording if tests met; customer accounts for VAT

Possibly yes

VAT-registered CIS contractor, genuine reduced-rate qualifying conversion

Reduced rate face - reverse charge can still apply where RC tests met (not zero)

Possibly - take advice

End user (even if company)

Normal VAT rules

Usually no reverse charge

Scaffold, lantern, bi-folds and specialist trades on the invoice

Orangery jobs often need access and almost always involve a roof lantern, glazing and often bi-folds. How you show those lines changes clarity and sometimes CIS/VAT paperwork.

Pattern

How to invoice

Tip

You hire scaffold and include in package

Line: "Scaffold hire period ... ticket ..." plus labour

Keep hire ticket on file

Separate scaffolder bills householder/contractor

Your invoice excludes scaffold; note "scaffold by others"

Cleaner for CIS paperwork

Lantern manufacturer bills you

Materials at direct cost (lantern purchase) on your CIS split

Keep delivery note / purchase invoice

Glazier as your subcontractor

Package lantern glass / side glazing lines on your invoice; keep their invoices

Do not double-bill the customer

Bi-fold supplier bills you

Doorset at purchase cost as materials; fit as labour

Spec upgrades as variations

Electrician as your subcontractor

Package electrical lines on your invoice; keep their invoices

See electrician invoice template

Electrician bills householder directly

Note "electrics by others"

Customer holds Part P paperwork

Bricklayer builds dwarf walls for you

Package dwarf-wall lines; keep their invoices

See builder guide

UFH specialist bills separately

Note "underfloor heating by others" or package if you subcontracted

Manifold / zone clear on drawings

Deposits and staged payments for orangery packages

Orangery jobs burn cash on brick/stone, steels, roof lantern, insulated flat-roof materials, bi-folds and glazing before the customer sees a weathertight room. If your terms require a deposit, raise a numbered deposit invoice before ordering stock, then credit it on stage or final invoices. See the deposit invoice template.

Stage (illustrative pattern)

What it usually covers

Stage 4 - snag / retention

Touch-ups; retention release if contract uses it

Figures for deposit percentages are commercial choices - mark them illustrative only when you show examples. Do not invent "industry standard" percentages.

Variations and retention

Extra bi-folds, a larger roof lantern, insulated flat-roof upgrades, electrical socket adds, underfloor heating, flooring upgrades, kitchen hybrid fit-out changes, or client-driven size changes should be written variations referencing the original quote - not silent increases on the final total.

Variation type

Invoice wording pattern

Larger / upgraded roof lantern

Variation V1 to quote Q-...: supply and fit upgraded roof lantern as drawing ...

Extra bi-fold / sliding door

Variation: supply and fit additional bi-fold as sketch ...

Insulated flat roof upgrade

Variation: revise flat-roof insulation build-up to ...

Electrical add

Variation: additional lighting circuit / sockets as drawing ...

Underfloor heating add

Variation: add wet/electric UFH as drawing ...

Variation: revise kitchen hybrid scope as revised drawing ...

Scaffold extension

Variation: extra scaffold week(s) ticket ...

Foundations deeper than assumed

Variation: extra excavation and concrete to engineer instruction EI-...

Size / projection change

Variation: revise orangery size as revised drawing ...

If 5% retention is held to practical completion or end of defects on a contractor package, show retention withheld and later retention released on separate lines so cash collected matches the certificate. Do not bury retention inside a vague "balance" line.

For householders, keep consumer-friendly stage language. Do not paste commercial retention machinery onto a domestic orangery unless the written contract actually uses it.

If a later variation adds installation labour under the same contract, revisit mixed-contract CIS rules (CISR14020 / CISR14030) - supply-plus-install of a lantern / orangery package can pull the whole contract into CIS.

Building Control, planning and Party Wall - the invoice is not a certificate

An invoice is a request for payment and a commercial record. It is not:

  • a Building Control completion or final certificate

  • planning permission or lawful development / permitted development confirmation

  • a Party Wall Act award

  • an electrical Part P / competent person notification

  • structural engineer sign-off (unless that professional issues their own document)

Orangeries often need Building Control and may sit under permitted development assumptions or need planning depending on size, location and local rules - that is the client's planning position, not something your invoice proves. If you collect a Building Control fee from the client, show it as a clear disbursement or fee line with the receipt reference. Do not imply the invoice itself is the approval. If Party Wall notices or awards are handled by a surveyor, keep that paperwork separate and optionally reference award numbers on the invoice ("Party Wall award PW-... issued separately"). Neighbour disputes and access licences are legal matters - not invoice line items that prove consent.

InvoiceAdept does not issue Building Control certificates, planning permissions or Party Wall awards.

Late payment (brief)

The Late Payment of Commercial Debts (Interest) Act 1998 is a B2B regime, not an automatic right against private householders. For qualifying commercial debts, statutory interest is Bank Rate plus eight percentage points under SI 2002/1675. Bank Rate was held at 3.75% on 30 July 2026, so the statutory rate is 11.75% a year for interest periods while that Bank Rate applies - always check the live Bank of England rate for later periods. The next Bank of England decision referenced for context is 17 September 2026. Fixed compensation bands are £40, £70 or £100 according to debt size.

Do not paste those commercial words onto a consumer householder invoice. Use fair consumer terms agreed before work, a clear due date and proportionate reminders.

Making Tax Digital means records, not filing

InvoiceAdept creates and stores invoice records. It does not file VAT returns, CIS300, MTD updates or Self Assessment to HMRC. It does not decide whether an orangery package is standard- or reduced-rated. It does not submit Building Control notices, planning applications or Party Wall paperwork.

MTD for Income Tax Self Assessment phases in by turnover: over £50,000 from 6 April 2026; £30,000 from April 2027; £20,000 from April 2028. InvoiceAdept keeps records; it does not submit quarterly updates.

Quote versus invoice versus retention on contractor orangery packages

A quote is an offer. An invoice is a request for payment against agreed or certified work. Retention is a contract term, not a tax rule.

FAQ

Does an orangery come under CIS?

Often yes when a CIS contractor pays you for orangery alteration or extension works. Prefer CISR14100. Use CISR14240 when works are part of a preparatory or finishing package (including plastering and insulation as part of the project). A private householder paying you directly is not a CIS contractor.

Does a householder deduct CIS from an orangery installer?

No. A private householder is not a CIS contractor. Domestic orangery invoices should not carry CIS deduction blocks.

Are rear, side-return and brick-base orangeries with roof lanterns within CIS for contractor jobs?

Typically yes when a contractor pays for alteration or extension of a building (CISR14100), or as finishing/prep within a wider package (CISR14240). Split labour and materials; show UTR and verification as your process requires. Name the roof lantern and dwarf walls on the face so the QS can match the package.

What if I only supply the roof lantern with no installation?

Manufacture and delivery without installation is generally outside CIS (CISR14220). Mixed contracts that also include install need careful reading of the mixed-contract rules (CISR14020 / CISR14030) - supply-plus-install of a lantern / orangery package can pull the whole contract into CIS.

How do I treat a roof lantern purchase for CIS?

If you purchased the lantern, materials are usually the purchase cost of that unit; labour is the installation. Keep the supplier invoice. Free-issue lanterns from the contractor are not your materials (CISR15060 / CISR15090).

What can I treat as materials for CIS on an orangery job?

The direct cost of materials you paid for on that contract - brick, stone, concrete, steel, roof lantern, insulated flat-roof materials, bi-folds, glazing, seals, cable, UFH pipe/mats - supported by evidence (CISR15060 / CISR15090). Mark-up is not direct-cost material. Free-issue materials from the contractor are not your materials.

Is an orangery VAT free in the UK?

Usually no. An ordinary rear orangery or brick-base orangery with roof lantern on an occupied existing home is typically standard-rated at 20% if you are VAT-registered. Soften absolute claims; check VAT Notice 708 and your adviser. Calling a room an "orangery" or adding a lantern does not create a VAT-free claim.

When can orangery works be 5% VAT?

Possibly when Notice 708 conditions for a qualifying residential conversion, empty-home renovation (typically empty 2+ years), or non-residential to dwelling conversion are met. Soften absolute claims; document the facts and take VAT advice. A kitchen hybrid label or bi-fold upgrade does not create a 5% claim on an occupied house by itself.

When does reverse charge apply to orangery invoices?

When the domestic reverse charge tests are met: both parties VAT-registered, the supply is construction services reported within CIS, standard or reduced (not zero), and the customer is not an end user. Never reverse-charge a householder. See the DRC invoice guide.

Should I invoice a deposit before ordering the roof lantern, steels or bi-folds?

If your terms require a deposit, yes - raise a numbered deposit invoice, then credit it on stage or final invoices. See the deposit invoice template.

How should I invoice a larger roof lantern or extra bi-fold?

As a written variation referencing the original quote, not as a silent increase on the final total.

How should underfloor heating and electrics appear on my orangery invoice?

If included in your package, show clear electrics and underfloor heating lines (labour and materials at direct cost for CIS). If specialists bill the householder or contractor directly, note "electrics by others" / "UFH by others". See the electrician invoice template.

How is an orangery different from a conservatory on the invoice?

An orangery typically has brick or stone dwarf walls, more solid wall area, and a larger roof lantern and/or insulated flat roof sections. A glass-box conservatory usually has more glazing and a fully glazed polycarbonate or glass roof. Name the product correctly so the customer and QS are not arguing about scope.

Does InvoiceAdept file CIS, VAT or MTD returns, or issue Building Control / planning certificates?

No. It creates and stores invoices. CIS features are on Pro+ at £12.99 excl VAT; Pro is £7.99 excl VAT with WhatsApp send; Free is five invoices per month. It does not file CIS300, VAT returns, MTD updates or Self Assessment and does not decide tax status. It does not issue Building Control certificates, planning permissions or Party Wall awards.

What CIS rates should appear if the contractor deducts?

20% verified, 30% unverified, or 0% with gross payment status - whatever verification outcome applies. InvoiceAdept does not verify you with HMRC.

Is the VAT registration threshold still £90,000?

Yes - £90,000. Do not use the stale £85,000 figure as if it were current. Deemed contractor construction spend is more than £3 million, not £1 million.

About this guide

Written for UK orangery installers, builders and subcontractors who need householder and contractor invoices that survive QS review and CIS/VAT scrutiny. Last reviewed 6 September 2026. Canonical URL: https://invoiceadept.com/blog/invoicing/orangery-invoice-template-uk/.

General information only - not tax, legal, Building Regulations, Party Wall or planning advice. InvoiceAdept is a product of Tech Me Today Ltd, Companies House 15917255, ICO ZB944663.

Bottom line

Name the orangery type, foundations, brick/stone dwarf walls, roof lantern and insulated flat roof. Split labour and materials for CIS - and remember CISR14100 for contractor-paid alteration/extension packages, with CISR14240 when finishing/prep applies. Keep householder invoices free of CIS. Treat VAT carefully - ordinary occupied-home orangeries are usually 20%, not VAT-free, and Notice 708 must be softened. Use deposits and variations for multi-stage packages. InvoiceAdept helps you issue the paperwork; it does not file HMRC returns or issue certificates.
