Crowther Solutions Ltd provides SAP calculations and building compliance advice for projects across the UK.

With experience in the construction and energy assessment sector dating back to 2005, we work with architects, developers, builders and homeowners to help projects achieve compliance from the design stage through to completion.

Our approach goes beyond simply producing a Pass or Fail result. We review the specification, identify where performance can be improved and provide practical advice to help achieve compliance without unnecessarily over-specifying the building.

Our founder is a Member of the Chartered Institute of Building (MCIOB) and a fully qualified, Elmhurst-accredited Energy Assessor, giving clients direct access to experienced technical advice throughout their project.
