Hi,
We can confirm that you can treat the cost of replacing the kitchen & bathroom as a repair.
You carried out the refurbishments to bring the rooms up to todays standards and replaced old with new more modern facilities... the work is a repair and not an improvement if, after the work is carried out, the asset can just do the same job as before.
Further information can be found at:
PIM2025 which links into
BIM46900 and this particular scenario is covered at

Thank you.
