For periods before 6 April 2013 HMRC permitted a deduction for the cost of renewing carpets, curtains and white goods in all let residential properties on a concessionary basis. That concession was withdrawn with effect from 6 April 2013. The new rules now state that a wear and tear allowance (10% of the net rents) that covers furnishings and similar items, can only be claimed for fully furnished properties.
Your clients properties don’t count as fully furnished, even though they contain some white goods and carpets. HMRC will not accept claims for the cost of free-standing white goods in unfurnished residential properties. It will allow a deduction for the cost of replacing fixtures such as baths, toilets, integrated fitted ovens and hobs, as those costs can be classified as repairs. If your client replaces part of the fitted carpet they could claim that as a repair, but not the cost of putting new carpet down in the entire property.
