Thanks that's helpful.
1. The lap top is about three years old now and I didn't claim expenses for its purchase. Too late now I imagine. From your answer I conclude that I can claim half of the broadband cost and half of any repairs.
2.The barn is used occasionally for table tennis and parties. The ratio of business to personal use is about 95% business and 5% personal. I have used the barn for this business for the past 9 years but have only previously claimed, rightly or wrongly, for carpet cleaning and interior decoration.
The rendering has been done on the outside walls and roof repairs involved replacing tiles.
Thanks for a clear answer to my question. I think I need a reply from you which will enable me to complete the rating which will be excellent.
