Our Process

We offer a simple, fast and reliable service, which includes much more than certificates. We act as part of your team, offering advice so that your project can reach its optimal thermal performance.

As soon as we receive your documentation we will issue you with a fixed price fee proposal describing the scope of your work, timeframe and cost. After this has been accepted our work will commence on a draft report for your review. Once confirmation is received you will receive your certification documents including:

  • BASIX / BESS certificate
  • Stamped set of drawings
  • Assessors certificate (included in the set of drawings)
  • Thermal performance Specifications (attached to the Assessors certificate)

Don’t hesitate to give us a call if you need any information about BASIX, NatHERS, BESS, NABERS or Section J reports.
