What an extension quote should make clear
The quote should show what is included, what is excluded, what is assumed, and what could change.
Before you commit to the build
Extension quote review for homeowners
An extension quote is more than a price. It is a set of assumptions about drawings, scope, ground conditions, access, finishes, and risk.
Where homeowners get caught
Problems usually sit around groundworks, drainage, steels, finishes, access, VAT, and provisional sums.
How TBG helps
We combine quote review with wider extension advice, so you are not only checking pounds and pence but also the build decision behind it.
The position
Quote review is the doorway. Extension advice is the service.
Most homeowners first feel the problem when a builder quote lands, a deposit is requested, or two prices do not match. That is where TBG enters the conversation, then widens the advice to the project risk behind the quote.
Best next step
If you are not sure which route fits, start with the Quick Review. If you have multiple quotes or detailed drawings, use the detailed quote review or East Midlands site survey.
