CGT on sale of second home

I have sold my second home. When I bought it the property was in a poor state but habitable. I replaced the old kitchen and 2 bathrooms with new, luxury, versions at a cost of £50k. As part of this renovation I also decorated throughout. These works led to a 22% increase in value in 3.5 years. Can I claim these works as improvements for capital gains purposes?

Hi ,
 

The kitchen and bathroom yes, decorating no  . Thank you .
