What is a new-build home?

A new-build home is a house built from the ground up on a plot, whether a one-off self-build for your family or a small group of homes. Building a new dwelling is usually zero-rated for VAT when carried out by a VAT-registered builder, which is a major cost difference from extensions and renovations.

This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.

What should I think about before starting?

Utility connections (water, sewer, power) can take months to arrange, so we apply early.
Self-builders can usually reclaim VAT on certain materials through HMRC’s DIY housebuilders scheme where they buy them directly.
