How to choose between them

  • Check the registration yourself. Trade body memberships are public, and each body's own register confirms them in a minute.
  • Get three quotes on the same specification. Written down, split into labour, materials and anything structural. Most people compare a total against a total and end up choosing between two different jobs.
  • Ask what is not included. Making good, waste removal, scaffolding and VAT are the four that turn a cheap quote into an average one.
  • Never pay a large deposit up front. Materials in advance is normal. Half the total before anyone turns up is not.

Extension builders in Wolverhampton: common questions

How far can I extend without planning permission?

Under permitted development, three metres for a terrace or semi and four for a detached, doubled to six and eight under the prior approval process. Height, materials and how much garden you cover all carry separate limits, and none of it applies in a conservation area.

Do I need a party wall agreement?

If you are excavating within three metres of a neighbour's foundations or building on the boundary, yes. You must serve notice two months before work starts. Skipping it is the most common reason extension projects stall.
