Frequently Asked Questions
How much can I claim?
HMRC's flat rate is £10/week (was £6 pre-2020, increased). For 52 weeks that's £520/year, no receipts required. Detailed-claim mode (proportional bills) can yield higher amounts but needs evidence.
Do I need receipts for the flat rate?
No: HMRC's whole point with the flat rate is to remove the receipt-keeping burden.
Does it reduce corporation tax?
Yes. The allowance is a deductible business expense, so it reduces taxable profit and the resulting CT.
Can I claim if I only work from home some days?
Yes. Pro-rata. Configure your WFH cadence and we'll only post for those weeks.
Detailed claim mode: when's it worth it?
If your actual home-office costs are materially higher than £520/year (typically a defined room with high utility usage). Chat will help you decide.
