The Two Methods

If you work from home in the UK, HMRC doesn't expect you to pay for your broadband or heating entirely out of your own pocket. However, you must choose one of two ways to calculate your deduction.

The Short Answer

You must choose: Simplified Flat Rate -OR- Actual Proportioned Costs.

The Simplified method is fast and requires zero receipts. The Actual method can save you more money but involves an afternoon of math and spreadsheets.

Method 1: Simplified Expenses

This is the "Headache-Free" option for freelancers who spend more than 25 hours a month working from home. Instead of tracking heating bills, you claim a flat monthly amount.

25 - 50 Hours / Mo
£10 / mo
Casual Use
51 - 100 Hours / Mo
£18 / mo
Part-Timer
101+ Hours / Mo
£26 / mo
Full-Time Studio
Important Note

The Simplified Rate ONLY covers heating and lighting. You can still claim for your business phone calls and a proportion of your broadband on top of these figures.

Method 2: Actual Costs

If you live in a large house or have very high heating bills, the flat rate might be too low. You can instead calculate the exact percentage of your bills that relates to your business.

Real Example: Aisha

Aisha has a 5-room house. She uses 1 room solely for her design business of the time.

Total Annual Heating£2,000
Business Share (1/5 Rooms)-£400
Council Tax Share (20%)-£300
Total WFH Deduction£700

Takeaway: Aisha can claim 1/5th (20%) of her council tax, heating, and lighting as a business expense.

What Can You Claim?

If you use the Actual Costs method, here is a checklist of the bills you can proportion.

Deductible Home Bills:

  • Heating & Lighting: Essential for your workspace.
  • Water Rates: Usually a small proportion.
  • Council Tax: Based on the number of rooms used.
  • Mortgage Interest (NOT capital): Proportioned by room.
  • Rent: If you are a tenant, you can proportion your rent.
  • Broadband & Phone: Based on actual business usage.

Your Next Step

Don't leave money on the table. A home office is one of your biggest tax-saving opportunities.

Frequently Asked Questions

Partially. You can claim for the interest portion of your mortgage payments if you use the 'Actual Costs' method, but NOT the capital repayment. If you use Simplified Expenses, mortgage interest is technically included in the flat rate.
If you have a room 100% dedicated to business (no personal use at all), you might owe Capital Gains Tax on that portion of the house when you sell it. This is why most freelancers ensure their 'office' has a secondary personal use (like a guest bed or storage).
No. HMRC considers 'refreshments' a personal expense. Only meals eaten while traveling to a temporary location away from your home office are usually deductible.
