Credit d'impots

[Me0wp00]

Hi

Im trying to price our renovation of a grange, I realise as it's a total renovation we'll be charged 19.6% TVA but will we get the credit d'impots on anything ?? reading through I don't think we will on insulation, certain heating but am I right in that we would from heat pumps or solar heating ?

Also, if we finish the grange and wait two years (is it 2 years from the h1 form) I take it we'd be entitled then if the credit is still going, I'm contemplating a wood pellet boiler but if we're not going to get the 50% off then i'd rather put oil in and wait two years to install the pellet one ??

thanks in advance
