How it works

  1. 1

    Tell us about the project

    A few short questions about the type of project, its stage and where it is.

  2. 2

    Upload drawings or specifications

    PDF plans, elevations, sections and specifications are all helpful.

  3. 3

    We review everything and confirm your quote

    Our SAP assessor checks everything and contacts you if anything needs confirming.

A more accurate quote from the start

We ask for enough information to understand your project properly before we quote. That means fewer surprises later and a fixed price based on the work actually required, rather than a generic headline figure.

You do not need to know every technical answer. If you have drawings or specifications, we can take much of the information from those and confirm anything missing with you.

  • Choose "I'm not sure" on any question without being blocked
  • Upload drawings now or send them later
  • Save your progress and return whenever suits you
