Energy efficiency
Select the energy improvements you’re considering — loft insulation, cavity wall insulation, heating controls — and we’ll estimate the annual saving, likely cost and which upgrades give the best value.
Figures are illustrative only and not property-specific. Your actual EPC or Home Report will use detailed information about your home.

Energy Performance Certificates (EPCs) and Home Reports usually group recommendations into low, medium and higher-cost improvements, showing an estimated annual saving beside each.
This calculator follows that same layout — but makes it interactive and adds a “quick wins” section, so you can instantly see which upgrades give the fastest payback.
The exact figures for your home will vary depending on its size, age, construction and heating system, but this gives you a realistic guide before you commission a Home Report or energy assessment.
Your actual EPC uses detailed information about your specific home, construction and heating system. This page uses typical values to give a general guide to savings and payback.

No. In Scotland you must have a valid Home Report, but you don’t have to complete every energy recommendation before you market your property.
Yes. Let them know what you’ve done — visible, confirmed improvements can usually be taken into account when they prepare the EPC or Home Report.
