With remote and hybrid working continuing into 2025, many self-employed individuals are asking: what home office expenses can I claim for tax relief? HMRC allows self-employed workers to deduct certain costs, provided they are used wholly and exclusively for business purposes. This guide explains what you can and cannot claim.
1. Who Can Claim Home Office Expenses?
If you are self-employed and regularly use your home for business, you can claim a proportion of your household costs. This applies whether you are a:
- Sole trader
- Freelancer
- Partner in a business partnership
2. Allowable Home Office Expenses
You can claim for the portion of household expenses directly linked to business use, such as:
- Utilities – Gas, electricity, water
- Council tax – Proportionate share
- Rent or mortgage interest – Business use only (not capital repayments)
- Internet and phone bills – Business-related calls and usage
- Repairs and maintenance – For the business area of your home
3. Two Ways to Claim
a) Flat Rate Method (Simplified Expenses)
HMRC provides a flat monthly rate based on hours worked from home:
- 25–50 hours/month → £10
- 51–100 hours/month → £18
- 101+ hours/month → £26
This is simple but may result in a lower deduction compared to actual costs.
b) Actual Cost Method
This method calculates the exact proportion of household expenses used for business.
- Example: If you have 6 rooms and use 1 as an office, that’s 16.6% of household costs
- Adjust for part-time use of the space
4. Expenses You Cannot Claim
- Personal or family-related costs
- Full mortgage repayments
- Decorating or improving areas not used for business
Claiming 100% of a household expense may risk HMRC challenges and could trigger Capital Gains Tax (CGT) when selling your home.
5. Record Keeping Requirements
- Keep bills, statements, and digital records of internet/phone use
- Track working hours if using the flat rate method
- Retain documentation for at least 5 years after the filing deadline
