About CES Energy

Independent assessors, on your side of the table

Chapman Environmental Services brings decades of combined experience across design, construction and development to every energy compliance certificate we issue.

We started CES Energy because compliance had become a black box: vague quotes, slow turnarounds, and reports you could not see until you had paid. We do the opposite. We publish our pricing, show our work, and explain the specification in plain language so your project moves.

Because we are independent of suppliers, our recommendations are impartial. Because our team has built and developed, our advice is buildable. And because we cover the full pathway, from BASIX and NatHERS through to Section J and JV3, you only ever deal with one accredited team.

How we work

Three things we will not compromise on

Independent

We hold no ties to manufacturers or suppliers, so our advice serves your project, not a product.

Accurate

Council-ready the first time. Our 100% approval record is the result of careful, accredited assessment.

Practical

We come from design, construction and development. We give specifications you can actually build.
