As I understand it you can, but that part of your house then ceases to be part of your main residence for capital gains tax purposes. This only becomes an issue when you come to sell your house. Normally any profit made on the sale of your main residence is exempt from capital gains tax, but a proportion of it that represents your office would become potentially taxable.
