Contracted 5% VAT on my barn conversion - then subsequent 5% refund

[Jakekibb]

Is anyone able to advise please on the above.

 

I'm converting my barn with full planning, contractor is used to dealing with 0% VAT with new builds but not the 5% with conversion. 
 

am I correct in that he should charge me 5% VAT on the majority of materials (I know there are some exceptions) and labour and then after completion I can look to claim a fair bit of this 0% back? 
 

the barn house is for me and the family fyi.

Yep, that's how mine worked. Plus recovery of 20%VAT on any materials you purchase directly, that aren't part of a supply and fit engagement.
