Planning checklist, not an EPC assessment

Sequence energy improvements before spending.

Record the home, select possible measures and replace the editable example figures with quotations and property-specific estimates.

01

Home and target

No score uplift is calculated or promised.

Possible measures and editable planning figures
Investigate damp, roof and ventilation before covering fabric.
Clear loft; maintain eaves ventilation and safe electrical clearances.
Survey wall construction, moisture risk, detailing and permissions.
Check compatibility with the existing heating system.
Heat-loss survey, emitters, hot-water storage and electrical supply first.
Roof condition, shading, structure, wiring and permissions first.

Plan fabric, ventilation and heating together

Insulation and draught work can change ventilation needs. Heating changes should follow a heat-loss assessment, and solar or battery work may depend on roof condition, electrical capacity, permissions and export arrangements. Flats, listed buildings and traditional construction can need specialist consent and moisture-aware design.

What to verify

  • Ask an accredited domestic energy assessor what evidence and modelling apply to the home.
  • Use competent installers and property-specific surveys and quotations.
  • Check current grant eligibility directly; schemes, dates and household rules change.
  • Do not treat a simple payback ratio as a guarantee: behaviour, weather, tariffs and performance vary.
