From 6 April 2020 the amount of tax relief you can claim from HMRC to cover the cost of additional household expenses incurred through being required to work from home has increased to £6 per week.

HMRC have said that those employees working from home due to Covid-19 office closures will be able to claim.

Claims can be made either online or by post by following this link: https://www.gov.uk/guidance/claim-income-tax-relief-for-your-employment-expenses-p87

It has been advised that it would probably be best to make one claim for all the period of home working upon return to the office.
