Overtime invoice template UK (2026): uplift rates, CIS, VAT
Overtime invoice UK, short answer: if you bill a private householder for overtime labour on their own home, it is a normal invoice and usually no CIS - the householder is not a CIS contractor. If you bill a main contractor or construction business for overtime labour on construction operations, the payment may fall under the Construction Industry Scheme when they pay you as a subcontractor - check HMRC’s public CIS guidance and the CISR manuals with your accountant; do not invent rates. Overtime does not create CIS by itself - CIS turns on construction operations and who pays you, not the clock. If you are VAT-registered (threshold £90,000), show VAT correctly; if you are not registered, do not charge VAT.
An overtime invoice bills hours beyond an agreed weekday day or contracted week, usually as a clear uplift on the weekday base rate. It is not a Saturday/Sunday weekend package, not a named bank-holiday premium, not a plain hourly bill with no uplift, not a first-attendance call-out fee, not a closed day-rate package, and not a timesheet reconciliation page alone.

Who pays, CIS and VAT on an overtime invoice
Start with who is paying you. That decides whether CIS language belongs on the invoice. Extra hours do not.
Who pays you | Typical overtime job | CIS? | VAT if registered |
|---|---|---|---|
Private householder | Weekday evening finish beyond agreed day on their own home | Usually no | Often 20% on ordinary domestic labour - soften Notice 708; do not invent 0% |
Main contractor / CIS contractor | Extra hours on a live site beyond the agreed day or week | May apply on construction ops - HMRC CIS / CISR; ask accountant | Normal VAT, or reverse charge only when eligible contractor tests met - never on a householder |
Landlord / managing agent (commercial) | After-hours attendance on a rental | Depends who the CIS actor is - soften | Usually 20% if registered unless a relief clearly applies |
Materials-only / no labour | Parts drop only | Generally outside CIS | Usually 20% if registered |
CIS rates (0% / 20% / 30%) sit with the contractor and your status - InvoiceAdept does not decide status and does not file CIS300. Soften absolute claims. Start with HMRC's CIS overview and CISR manuals (e.g. CISR14100 / CISR14240). VAT threshold is £90,000; £85,000 is stale. InvoiceAdept does not file VAT returns, MTD updates or Self Assessment.
Overtime vs weekend vs bank holiday vs hourly vs call-out vs day rate vs timesheet
Use this page when the deal includes an overtime / after-hours uplift on a weekday base. Sister pages stay for sister intents.
Billing shape | When it fits | Invoice cue |
|---|---|---|
Overtime (this page) | Hours beyond agreed weekday day or contracted week | Base + overtime uplift on separate lines |
Sat/Sun premium package | Weekend day or Sat/Sun uplift | |
Named public holiday premium | Holiday date + premium line | |
Hours x rate without an overtime uplift package | Hours x rate; clock times help | |
First-attendance / emergency fee plus labour | Call-out fee, then labour | |
Agreed day or half-day attendance | Day rate x days with dates and site | |
Signed sheet / dayworks the QS will check | One line per sheet row; quote DW number |
An overtime job can still sit on a timesheet or include a call-out - but the intent here is the uplift for hours beyond the agreed weekday envelope. Do not silently convert a weekday quote into overtime without written agreement.

Your name or business name | Yes | Match Self Assessment / Companies House |
Your address and contact | Yes | Email helps householder and QS queries |
Customer name and address | Yes | Ltd = registered name; add site if different |
Unique sequential invoice number | Yes | e.g. INV-OT-2026-0014 |
Invoice date | Yes | Date of issue |
Tax point / supply date | If VAT-registered and different | Useful when attendance runs past midnight |
Description of services | Yes | Date, clock times, site, base vs OT uplift; "householder - no CIS" when true |
Quantity / unit price / nets | Yes | Split base hours, OT uplift, materials, deposit |
Payment terms | Yes | Due on receipt / 7 / 14 days |

Put base rate and overtime uplift on clear lines. Separate materials when CIS may apply. Never reverse-charge a private householder.
Worked example: one overtime invoice
Illustrative only. Sole trader, not VAT-registered, private householder, Tuesday evening finish beyond the agreed 8-hour day with 1.5x uplift on the extra hours and a deposit already taken. No CIS.
Line | Detail | Qty | Rate | Net |
|---|---|---|---|---|
1 | Labour - weekday base, Tue 15 Sep 2026, 08:00-16:00, 9 Oak Close (householder; no CIS) | 8 hrs | £50.00 | £400.00 |
2 | Overtime uplift - after agreed day, 16:00-19:00 (show uplift only @ 0.5x base) | 3 hrs | £25.00 | £75.00 |
3 | Materials - fixings at cost | 1 | £42.00 | £42.00 |
4 | Less deposit received 14 Sep 2026 (INV-DEP-2026-011) | 1 | -£100.00 | -£100.00 |
Subtotal | £417.00 | |||
VAT | £0.00 (not VAT-registered) | |||
Total due | £417.00 |
Payment terms example: Due within 7 days. Invoice INV-OT-2026-0014. Build it in the free invoice generator. If the same overtime hours go to a CIS contractor for construction ops, split labour vs materials and follow their deduction process - do not invent rates. Deemed contractor framing on construction spend is £3 million, not £1 million.

Not VAT-registered | Do not add VAT lines |
VAT-registered domestic labour | Often 20% - soften Notice 708; no invented 0% |

Agreeing uplift rates before you stay late
Agree the overtime multiplier or flat OT rate before you stay past the agreed day.
Shape | How to show it on the PDF |
|---|---|
Multiplier (e.g. 1.5x / 2x) | Line 1: base hours x weekday rate; Line 2: OT hours x (premium - base) |
Flat OT hourly | OT hours x agreed OT rate on its own line |
After-hours window | Clock times + OT premium on its own line |
Call-out + overtime labour | Call-out fee first, then base + OT uplift |
Weak: "Overtime as agreed £280." Usable: "Tue 15 Sep 2026 base 08:00-16:00 8 hrs @ £50 + OT 16:00-19:00 3 hrs uplift @ £25, materials £42, less £100 deposit - householder, no CIS."
Payment terms and getting paid
Send the invoice the same day you finish. Domestic overtime jobs often use due on receipt or 7 days; contractor AP often 14 or 30. Put bank details on the PDF. Soften any B2B late-payment interest wording with the contract and your accountant.
Common mistakes on overtime invoices
Mistake | Fix |
|---|---|
Vague "overtime labour" lump | Show date, clock times, base hours and OT uplift |
CIS on a householder invoice | Remove CIS lines when the householder pays |
Treating late hours as a CIS trigger | CIS = construction ops + who pays - not the clock |
Charging VAT when not registered | Net only until registered |
Stale £85,000 VAT language | Use £90,000 |
Silent weekday-to-OT uplift | Confirm the premium in writing first |
Mixing weekend / bank holiday labels | Use sister pages for Sat/Sun or named holidays |
Billing OT as a day-rate package | Use day-rate or overtime lines - not both confused |
Frequently asked questions
Does overtime trigger CIS by itself?
No. CIS depends on construction operations and who pays you. Extra weekday hours alone do not create CIS. Private householders are usually outside CIS.
Can I put CIS deduction lines on a householder overtime invoice?
Usually no. If a private householder pays you for work on their own home, leave CIS narrative off the PDF.
What VAT threshold should I use in 2026?
£90,000. Older £85,000 / £88,000 wording is stale. Soften registration edge cases with your accountant.
Is overtime the same as a weekend or bank-holiday invoice?
No. Overtime is uplift beyond an agreed weekday day or week. Use the weekend or bank-holiday templates when the premium is for Sat/Sun or a named public holiday.
How should I show a 1.5x overtime rate?
Show base hours at the weekday rate, then a separate uplift line for the OT hours (premium minus base), or a single OT hourly line if that matches the written deal.
Do I charge VAT on overtime if I am not VAT-registered?
No. Net only until you are registered. Registration is separate from whether the hours were overtime.
What is deemed contractor framing?
Public guidance often uses a £3 million construction-spend framing for deemed contractors - not £1 million. Soften with HMRC / your accountant; InvoiceAdept does not decide status.
Where can I build the PDF quickly?
Use the InvoiceAdept free invoice generator - Free covers 5 invoices; Pro is £7.99 and Pro+ £12.99 when you need more.
Next step: build the overtime invoice

Open the free invoice generator, paste the lines from the worked example shape, and send the same day. InvoiceAdept does not file CIS300, VAT returns, MTD or Self Assessment for you.
