About Ordellis
Clear advice.
Better-informed projects.
Residential building performance and compliance support for homeowners, developers, builders and architects across England, Wales, Northern Ireland and Scotland.
From the first drawing to the final evidence
A practical partner
for your design team.
Ordellis brings together residential energy assessments, overheating analysis, fabric calculations, planning statements, completion reporting and site testing. The work is scoped around the building, the applicable requirements and the stage of the project.
Start with a conversation about your proposal. Each quotation sets out the assessments, information requirements, reporting outputs and agreed delivery arrangements.
As the design develops, the calculations and specification need to develop with it. At completion, the final assessment should reflect the completed building and the evidence available.
What to expect

A defined scope.

Practical coordination.
