As your rental business consists of a FHL, they do not qualify for domestic items relief so Capital Allowances may be claimed when you replace furniture and white goods. We would advise that for items such as saucepans, frying pans, cutlery and so on, to consider pooling the items together and putting them in a short life asset pool. You can find more information here:
HS252 Capital allowances and balancing charges (2020)
If you disposed of any of the items as scrap or second hand, that is, you received payment for such items which have previously been claimed as a Capital Allowance, you may have a balancing charge. Again this is covered within the guidance above.
