Clearly, right now many firms have closed workplaces and that means across the UK millions of staff are temporarily required to work from home, even if it's just for part of the week, and therefore are eligible to claim for increased costs.
HM Revenue & Customs (HMRC) says it will consider claims from employees working at home due to coronavirus measures if their usual workplace is closed. HMRC says that claims in line with the employers' payment will not need to justify the £6 figure.
And that means you will not need to keep receipts or prove information.
There are various ways you can do it.
You can claim on a self-assessment form, or alternatively through an online P87 form through a government portal.
