Hi,
You have two options available.
If you meet the conditions and claim the rent a room relief - method A then you are allowed to receive income up to £7500 in a tax year which would be tax free.You cannot however deduct any expenses if you use this method.
You can use the method B rather then rent a room relief which is rents received minus expenses wholly incurred for the property business.
However if this income after expenses is over £1000 then it would be chargeable to tax.
You have mentioned 'personal' expenses. I assume you mean expenses you solely incurred in relation to the property business.
