Working From Home Tax Relief UK 2026/27: When You Can Still Claim

The working-from-home tax-relief rules tightened sharply after the pandemic. Many people who claimed during 2020-2022 still believe they can. Most can't any more. This guide tells you who qualifies in 2026/27, how much, and how to claim direct from HMRC for free.

The current rule (post-April 2022)

You can claim tax relief on a flat rate of £6 per week for additional household costs (heating, electricity, business calls) if your employer requires you to work from home.

The key word is requires. Working from home by mutual agreement, or through a hybrid arrangement of your choice, does not qualify. HMRC tightened this from April 2022 specifically to close the temporary lockdown-era looser eligibility.

Who qualifies in 2026/27

You qualify if:

1. Your employment contract requires you to work from home (your home is your normal place of work, OR you have no choice because your employer has no office available to you).
2. OR your employer requires you to work from home for specific health/safety reasons (e.g. a disability accommodation).
3. AND you actually incur additional household costs as a result.

You do not qualify if:

• You work from home as a personal preference that your employer accommodates.
• You're under a hybrid arrangement where you choose which days are remote.
• Your employer offers an office and you choose home anyway.
• You're self-employed (different rules - claim as a business expense in Self Assessment).
• You're already reimbursed for the costs by your employer tax-free.

The distinction between "required" and "permitted" is the entire game. HMRC's test: would you face a contractual disciplinary if you tried to work from your employer's office? If no, you don't qualify.

How much you can claim

Two routes:

Route A - The flat rate (£6/week)

The simple route. £6/week × number of qualifying weeks = your deductible amount. At basic rate (20%), that's £1.20/week refund. For a full year (52 weeks): £6 × 52 = £312 deductible × 20% = £62.40 refund.

For a higher-rate taxpayer: £312 × 40% = £124.80 refund.

No evidence required for the flat rate.

Route B - The actual amount

If your additional household costs are higher than £6/week, you can claim the actual amount - but you must be able to evidence it. This typically means:

• Itemised electricity bills showing the increased usage.
• Calculation of the proportion of the bill attributable to your work usage (typically a square-foot or room-count basis).
• Evidence of business telephone calls separately metered.

In practice, the actual-amount route is rarely worth it for employees - the maths usually doesn't beat £6/week once you've factored in the time. It's more common for self-employed individuals filing Self Assessment.

Backdating - claim up to 4 years

You can claim for the current tax year plus the previous four. The 2020/21 and 2021/22 tax years had temporary loosened eligibility during the pandemic (HMRC accepted "you were required to work from home for any part of the year, even one day" as qualifying). Many people claimed for those years already.

For 2022/23 onwards, the strict "required" test applies. If you've never claimed:

Tax year	Eligibility test	Claimable if eligible
2026/27 (current)	Strict - required to WFH	£312 × marginal rate
2025/26	Strict	£312 × marginal rate
2024/25	Strict	£312 × marginal rate
2023/24	Strict	£312 × marginal rate
2022/23	Strict	£312 × marginal rate
2021/22	Loose (any required day)	£312 × marginal rate
2020/21	Loose (any required day)	£312 × marginal rate (pandemic-era special rules apply)

A basic-rate taxpayer who's been required to WFH all five years (2022/23 to 2026/27) and never claimed could be due about £312 - pre-pandemic. If they were also required during 2020/21 and 2021/22, the maths is roughly £6/week × 364 weeks × 20% = around £437.

How to claim - the free DIY route

Online via Personal Tax Account

1. Sign in to your HMRC Personal Tax Account at gov.uk/personal-tax-account.
2. Search for "Tax relief for working from home" or follow the "Claim tax relief for your job expenses" route.
3. Confirm your eligibility (you'll be asked to confirm you're required to WFH).
4. Enter the years you're claiming for.
5. Submit.

HMRC adjusts your tax code so future relief flows automatically through PAYE, AND issues a refund for prior years.

P87 form (postal or online)

For higher-value claims or if you don't have a Personal Tax Account, file form P87 at gov.uk/government/publications/income-tax-tax-relief-for-expenses-of-employment-p87.

Honest framing - is this worth claiming?

For a basic-rate taxpayer, a single year's WFH relief is around £62. For five years, around £312. That's real money but not life-changing.

The reason we cover it anyway: if you genuinely qualify, claiming is free, takes 10 minutes, and HMRC adjusts your tax code so future months apply the relief automatically. The cost is low; the friction is the eligibility test.

If you're unsure whether you qualify, ask your employer's HR team to confirm in writing whether you're "required" to WFH (vs "permitted"). That confirmation is your evidence if HMRC asks.

Why we do not recommend a refund firm for this

The flat-rate WFH claim is HMRC's simplest expense-relief category. The form is short, the eligibility test is binary, and the refund amount is small relative to a refund firm's commission. Paying 20-35% of a £62 refund (£12-£22) to have a firm do this for you is poor value.

Use a refund firm only if you have a multi-year, complex mix of expenses (mileage, uniform, professional fees, WFH all together) and your records are scattered or partial.
