Design SAP to lodged EPC and buyer energy sheet

We take off your hands: tracking design SAP, as-built SAP and EPC lodgement for each plot, checking substitutes and collecting the assessor's evidence.

You get: a plot-by-plot tracker of SAP and EPC status, substitutes checked for your technical manager, evidence for the assessor and an energy sheet for each buyer.

The problem

A buyer's completion was held up because the EPC wasn't lodged.

How the steps join up

It starts when: a plot's design is fixed and its design SAP is issued.

  1. Check each house type and plot against the Part O simplified method and flag those needing modelling

  2. Calculate water efficiency per house type from the fittings schedule and evidence the planning condition

  3. Track design SAP, as-built SAP and EPC lodgement for every plot

    Your team checks and decides at this step.

  4. Check product substitutions against each plot's energy assessment before they are fitted

  5. Check each plot's Part L photos are complete before details are covered

  6. Collect as-built M&E product data for the energy assessor's as-built calculations

    Your team checks and decides at this step.

  7. Give each buyer their home's energy data and running cost estimate to support a green mortgage

  8. Check every plot has its completion documents

What you end up with: Each plot passes overheating and water checks, substitutes are checked against its energy result, photographic and as-built evidence is complete for the assessor, the EPC is lodged before completion, and the buyer gets an energy sheet for their lender.

Who signs it off: Your energy assessor signs off SAP and the EPC, and your technical manager decides on any substitute.

What it needs to work

  • An energy assessor who shares results digitally
  • Air test results per plot

If those aren’t in place yet, you’ll hear that before anything gets built.

Who it’s for

  • Developers and housebuilders
