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 navigate the world 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.

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:

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.

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.
• Mortgage Interest or Rent: Claim a proportionate amount based on the workspace area.
• Council Tax: Similarly, a proportion of your council tax can be reclaimed.
• Property Insurance: If you have specific business insurance, this can be claimed in full; otherwise, a proportion of your home insurance.
• Repairs and Maintenance: Costs that relate directly to the workspace can be claimed fully, such as fixing a broken window in your home office.

How to Calculate Your Home Working Expenses

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.

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%.

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.

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. For more information on what records to keep, visit gov.uk.

Common Mistakes to Avoid

• Under-recording: Keep detailed records to avoid missing out on legitimate claims.
• Ignoring Changes: Tax rules can change, so keep updated with the latest guidance from HMRC.
