Everything can be claimed for.
Wear and Tear
For the damaged items you threw out, in the 2015 tax returns write off any remaining amounts.
You claim 12.5% of the new furntiure and white goods.
Repairs can be written off, skip, shower door, blinds, valves, grate.
No work of your own can be written off. I've no clue about your visits, maybe you can claim the cost of the petrol. As 3K seems low to me I'm assuming you did most of the repair yourselves. Did you not use paint?
