Working from Home Expenses for Self-Employed: What You Can Claim in 2026

Understanding Working from Home Expenses for the Self-Employed in the UK

As more tradespeople and self-employed workers in the UK embrace the flexibility and cost-saving benefits of working from home, understanding how to claim relevant expenses is important. Whether you're a plumber, electrician, or a freelance designer, knowing which home-related expenses you can claim can significantly reduce your tax bill. This guide will help you understand the intricacies of working from home expenses self-employed UK in 2026.

What Are Working from Home Expenses?

Working from home expenses are costs incurred as a direct result of running your business from your residence. The HM Revenue & Customs (HMRC) allows self-employed individuals to claim these expenses to ensure that your household costs do not unfairly inflate your business expenses. This is an important aspect of managing your finances effectively when your home doubles as your office.

Types of Home Expenses You Can Claim

There are two primary ways to claim home expenses: the simplified flat rate and actual costs. Let’s explore both in more detail:

Simplified Expenses

The simplified flat rate method is perfect for those who prefer an easy approach. It allows you to claim a flat rate based on the number of hours you work from home each month:

• 25 to 50 hours per month: £10

• 51 to 100 hours per month: £18

• 101 hours or more per month: £26

This method requires minimal record-keeping and is useful for those who use home as a workspace occasionally. It's particularly beneficial for tradespeople who may split their time between on-site work and home-based administrative tasks.

Many UK tradespeople also find it helpful to review allowable expenses for the self-employed at this stage.

Actual Costs

If you prefer to claim a proportion of your actual household costs, you’ll need to calculate the portion of your home used for business. This method can be more beneficial if you use a significant part of your home for work. Here are some costs you can claim:

• Utility Bills: Include a portion of your electricity, heating, and internet bills. For example, if you use one room in a five-room house, you might claim 20% of these costs. This can add up to significant savings over the year.

• Mortgage Interest or Rent: Claim a proportionate amount based on the workspace area. Suppose your home office takes up 15% of your living space; you can claim that same percentage of your rent or mortgage interest as a business expense.

• Council Tax: Similarly, a proportion of your council tax can be reclaimed. Make sure you calculate this accurately to avoid any issues with HMRC.

• Property Insurance: If you have specific business insurance, this can be claimed in full; otherwise, a proportion of your home insurance. It’s wise to talk to your insurer to ensure you have the right coverage.

• Repairs and Maintenance: Costs that relate directly to the workspace can be claimed fully, such as fixing a broken window in your home office. Remember to keep all receipts and invoices for such work.

For a complete calculation, consider using our Self-Assessment Calculator to ensure accuracy in your claims. This can help you avoid over- or under-claiming, both of which can lead to issues with HMRC.

How to Calculate Your Home Working Expenses

Calculating your home working expenses requires a methodical approach. Here is a step-by-step guide to help you get it right:

Step 1: Determine Your Workspace

Identify the area of your home used exclusively for business. This could be a dedicated office or a multifunctional room during working hours. Be honest with your assessment to avoid future complications.

If you are sorting this alongside other compliance work, read claiming mileage as a tradesperson.

Step 2: Calculate the Proportion

Divide the area of your workspace by the total area of your home. For example, if your workspace is 200 square feet in a 1,000 square-foot home, the proportion is 20%. This calculation is fundamental to determining how much of your household expenses can be claimed.

Step 3: Apply to Your Bills

Apply this proportion to your household bills to determine the business expense portion. Remember, only claim the business-related portion of shared bills. This ensures that you remain compliant with HMRC regulations.

Record-Keeping and Compliance

Maintaining accurate records is important. Keep invoices, receipts, and relevant documents for at least five years. This ensures compliance and prepares you for any potential HMRC audits.

Common Mistakes to Avoid

• Under-recording: Keep detailed records to avoid missing out on legitimate claims. Failing to claim all your allowable expenses can result in paying more tax than necessary, impacting your bottom line.

• Ignoring Changes: Tax rules can change, so keep updated with the latest guidance from HMRC. Regularly checking for updates ensures that you remain compliant and avoid unexpected tax liabilities.
