I wouldn't have thought we knew enough of the OP's status ie a contractor or whether the fees earned are from a single source infering an employee/employer relationship.
home costs are allowable in the form of
use of home as office. They have to be reasonable costs incurred and include
council tax
rent (not mortgage interest)
heating and lighting
cleaning
you total them for the house in total then apportion based on how many rooms in the house, applying one room as an office.
as for employing family, fine, but as others have said, it has to be justifiable and you may (or may not) have to register for PAYE depending on how much you pay them and how often.
in all of this just remember you are allowed to claim for costs incurred in running your business, but not costs that you would like to offset against your business income.
also, if you are going to pay divs then make sure that if you issue shares to your spouse that any divs they receive do not take them into the higher rate tax bracket as every £1 over this limit will see an extra effective tax charge of 32.5p
as everyone else has advised, pay to see an accountant, it will be money well spent.
