Calculate build cost per square metre using the same measured area.
This is most useful when the same project is being priced by several contractors and you want one additional way to understand the commercial spread.
Use the same measured area for every comparison.
For meaningful comparisons, use the same definition of area throughout, such as the same measured internal or gross internal floor area.
Enter up to four prices on the same VAT and scope basis.
A £/m² figure does not make unlike scopes comparable.
Use one area basis
Do not mix gross internal, net internal or extension-only areas. Use the same measured area for every quotation.
Use one price basis
Keep VAT treatment, exclusions, client-supplied items and provisional allowances consistent where possible.
Review scope separately
A lower rate may simply reflect less scope, a different specification or more exclusions rather than a better commercial offer.
Compare the quotations in more detail.
Use the quote comparison tool to keep VAT treatment, exclusions, provisional sums and programme duration visible alongside price.

Describe the scope, location, budget and programme so relevant construction companies can assess the opportunity.

Use it to make the next decision clearer.
Use the rate only after putting quotation totals onto a consistent scope and VAT basis. It is useful for spotting outliers, not for deciding which contractor is best.
Use it to reduce commercial ambiguity.
Use it to sense-check how your entered quotation sits against the same project's area, then explain any specification, preliminaries, access or risk factors that make the rate different.
Use it to support structured advice and procurement.
Use it as a secondary normalisation measure within tender analysis, never as a substitute for scope review, specification quality, risk allocation or elemental cost understanding.
You stay in control of what becomes public and when you connect.
BuildConnect separates useful marketplace information from private account details. The controls differ by role, so clients, contractors and professionals can participate without having to make everything public.
Clients
Client contact details remain private until the client chooses to connect with a contractor. Start with the project information rather than publishing personal contact details.
