Working from Home Tax Relief UK 2026 — How to Claim and How Much You Get

Guide to claiming tax relief for working from home in the UK. Who can claim, how much you get, how to apply to HMRC, and what expenses you can deduct.

Tax information is based on HMRC rules for the 2026/27 tax year. Tax rules can change — always verify current rates at GOV.UK. This is not tax advice. Consider consulting a qualified tax adviser for your personal situation.

If your employer requires you to work from home, you can claim tax relief on the additional costs — even with the flat-rate method that needs no receipts.

Millions of UK employees work from home at least some of the time, and many are entitled to tax relief on the additional costs they incur — extra heating, electricity, and broadband used for work. Yet the relief is widely underclaimed. The HMRC flat rate of £6 per week requires no receipts, takes around 10 minutes to claim online, and is worth £62 per year for basic-rate taxpayers and £125 for higher-rate taxpayers. That may not sound enormous, but you can claim for up to four previous tax years in one go — potentially worth £500 in one claim.

The single most important rule is that your employer must require you to work from home — it can’t simply be a personal preference or a perk your employer offers. This means many hybrid workers who choose to work from home some days without any requirement from their employer cannot claim for those voluntary days.

Who Can Claim?

Employed (PAYE)

SituationCan you claim?
Employer requires you to work from home (in your contract)Yes
No office space available for youYes
Nature of your job requires home workingYes
You choose to work from home (employer allows it as a perk)No
You work from home to avoid commutingNo
Hybrid working — employer requires some days at homeYes — for the days you are required to be at home

The key test: Your employer must require it, not just permit it. HMRC checks whether reasonable facilities in an employer’s premises are available for you.

Self-Employed

SituationCan you claim?
You work from home and are self-employedYes — through Self Assessment
You use a room for business (even part-time)Yes
You have a separate home officeYes

Self-employed people have more flexible rules — see the section below.

How Much Can You Claim? — Employed

Option 1: Flat Rate (No Receipts Needed)

DetailAmount
Flat rate£6 per week (£312 per year)
Tax saving (basic rate — 20%)£62.40 per year
Tax saving (higher rate — 40%)£124.80 per year
Tax saving (additional rate — 45%)£140.40 per year
Receipts needed?No
Evidence needed?You must genuinely be required to work from home

This is the simplest option and suits most people. You do not need to prove your extra costs — HMRC accepts £6/week as a reasonable allowance.

Option 2: Actual Costs

If your actual additional costs are higher than £6/week, you can claim the exact amount — but you need evidence.

Claimable costExample
Heating (extra)Proportion of gas/electricity for the room you use
Electricity (extra)Cost of running equipment, lighting
Metered water (extra)If applicable
Business phone callsCalls made for work (not line rental)
Internet (proportion)The business-use portion of your broadband
NOT claimableReason
Mortgage or rentPersonal housing cost — not an additional expense of working from home
Council taxPersonal cost
Food and drinkPersonal cost
Commuting costs savedNot a cost you’ve incurred
Furniture (desk, chair)May be claimable separately — see below

Calculating Actual Costs

StepMethod
1Identify the room(s) used for work
2Calculate the proportion of the house (e.g. 1 room of 5 rooms = 20%)
3Apply that proportion to your gas/electricity/water bills for the period you worked from home
4Deduct any amount already covered by your employer

Caution: If you designate a room exclusively for work, this could have Capital Gains Tax implications when you sell the property. Using a room for mixed purposes (work and personal) avoids this issue.

Claiming for Previous Years

You can claim up to 4 years back. If you were required to work from home in 2022/23, 2023/24, or 2024/25 and didn’t claim, you can still do so now.

Tax yearDeadline to claim
2022/235 April 2027
2023/245 April 2028
2024/255 April 2029
2025/265 April 2030

Equipment and Furniture

If Your Employer Provides Equipment

SituationTax implication
Employer provides laptop, monitor, chairNo tax on you — provided it is mainly for work use
Employer reimburses you for equipmentCheck — may be tax-free if it’s a business expense
You buy equipment yourselfMay be able to claim tax relief (see below)

If You Buy Equipment Yourself

ItemClaimable?
Desk, chair, monitor (used substantially for work)Yes — claim the full cost or capital allowances
Stationery, printer cartridgesYes
Computer (if required and substantially for work)Potentially — but HMRC may argue it’s for personal use too
Phone or broadband upgradeOnly the additional cost attributable to work

Claims for equipment go on form P87 (if under £2,500 total expenses) or your Self Assessment return.

Self-Employed — Working from Home

Self-employed people have two options:

Option A: Simplified Expenses (Flat Rate)

Hours worked at home per monthFlat rate deduction
25–50 hours£10/month
51–100 hours£18/month
101+ hours£26/month (£312/year)

No receipts needed. Claim on your Self Assessment tax return.

Option B: Actual Costs (Proportion Method)

StepAction
1Calculate total household costs (gas, electricity, water, broadband, council tax, insurance, rent/mortgage interest)
2Determine the proportion used for business (by room or time)
3Claim that proportion on your Self Assessment
ExampleCalculation
Total household running costs£12,000/year
Business room = 1 of 5 rooms = 20%£2,400
Used for business 50% of the time£1,200 claimable

For most self-employed people working from home full-time, the actual proportion method gives a higher deduction than simplified expenses. But it requires more record-keeping.

Employer Reimbursement

ScenarioTax treatment
Employer pays you up to £6/week (£26/month) for working from homeTax-free — no need to claim
Employer pays you more than £6/weekAmount above £6/week may be taxable unless you can prove actual costs
Employer pays nothingYou claim tax relief from HMRC yourself

Check your payslip — some employers already pay a working from home allowance. If so, you cannot claim tax relief on the same costs.

Common Mistakes

MistakeResult
Claiming when you’re not required to work from homeHMRC may reject the claim and ask for repayment
Claiming the COVID-era flat rate (which was more generous)The temporary COVID scheme ended April 2022 — standard rules now apply
Not checking whether your employer already reimburses youYou cannot claim relief on costs your employer covers
Designating a room exclusively for workPotential CGT issue when selling your property
Forgetting to claim for previous yearsYou can go back 4 years — don’t leave money on the table

Hybrid Workers — Special Rules

Many people now work partly from home and partly in the office. Here’s how the rules apply:

Working PatternCan You Claim?Notes
5 days home (employer requires)Yes — full £6/weekBest case
3 days home, 2 office (employer requires home days)Yes — for home daysClaim proportionally
2 days home (your choice), 3 officeNoMust be required by employer
Some days home when office unavailableYes — for those daysEven if irregular
Contractually home-basedYesContract is your evidence

Tips for Hybrid Workers

TipWhy
Check your contractDoes it specify home working?
Ask HR for confirmation in writingUseful if HMRC queries the claim
Keep a log of home working daysSupports actual costs claim
Don’t claim for voluntary home daysHMRC may reject the whole claim

Directors and Company Owners

If you’re a director of your own limited company, the rules differ:

ScenarioRecommended Approach
Director of own company, work from homeCompany pays you £6/week tax-free — this is a business expense
Director with home as registered officeCan additionally claim use of home as office
Director — higher costsCompany can reimburse actual costs — needs evidence

Setting Up Home Working Allowance Through Your Company

StepAction
1Board minute confirming home working requirement
2Add £6/week (£26/month) to salary — mark as expenses
3This is tax-free for you and a deductible cost for the company
4For amounts over £6/week — keep detailed records

Rent a Room to Your Company

Some directors rent a room in their home to their company. This uses different rules:

ConsiderationDetails
Market rate rentMust be reasonable (typically £200-£400/month for a room)
Rent a Room SchemePersonal tax-free up to £7,500/year
Corporation Tax deductionCompany deducts the rent
DocumentationNeed proper licence/rental agreement

Caution: Get accountant advice — this arrangement has specific requirements.

Capital Gains Tax Warning

If you use part of your home exclusively for business (rather than sometimes for personal use too):

  • That area could be liable for Capital Gains Tax when you sell the property
  • Private Residence Relief may not fully apply to that portion

Solution: Use the room for both business and personal purposes, even occasionally. Exclusive business use triggers the CGT risk; mixed use does not.
