Every building is different - the prices below are for guidance only. Property size, complexity, construction method, and specific requirements all affect the final cost. Please get in touch for an accurate quote tailored to your project.
SAP assessments are completed in two stages: the Design Stage SAP for your Building Regulations application, then months or years later, the As-Built review and EPC when your dwelling is complete. The As-Built stage involves reviewing any construction changes and producing the final EPC for lodgement.
Discounts available for developments of 5+ dwellings - where house types are repeated or specifications are consistent across plots, we offer reduced rates to reflect the efficiencies. Get in touch to discuss your project.

For more detailed regulatory guidance - whether you're at early design stage and want to avoid costly mistakes, or need advice on achieving compliance for a tricky project - our paid advisory service draws on 45 years of Building Control and Building Standards experience.
We ask for a £100 deposit on instruction for the Design Stage SAP assessment, with the balance due on completion of that stage. The As-Built review and EPC fee is payable when the dwelling is complete and you're ready for final certification. All invoices are payable within 14 days.
SAP assessments are a desktop exercise - there's no need for a site visit. Simply email us your drawings and specifications, and we'll take it from there.
