The new housing estate nearby means you’re rapidly outgrowing your current buildings, and you’re considering putting up a new block to help ease the pressure at the school.
Is the land actually in your ownership (either as part of your lease, or freehold)?
Check your lease if you have one – it will limit if and how you can put up new buildings
Do you need planning permission? Get some proper planning advice, whether from an architect, your lawyer or a formal planning consultant
Make sure you have a contract in place with whoever does the construction work to cover you for anything that goes wrong
Keep copies of all planning permissions and building regulation certificates handy, you’ll need them in the future
Don’t let anyone start building, demolishing, or site clearing without having all appropriate consents in place beforehand:
landlord
Department for Education (DfE)
planning permission might be required
Never agree to pay a builder ‘off the books’ to avoid VAT
