Home Energy Rating assessments

A home energy rating gives your existing home a star rating for how well it holds heat and stays cool. It’s a simple way to see how your house compares, and what would improve it.

A common sign

“How energy efficient is our house, really?”
A home energy rating gives you an answer you can compare. It also shows which changes would lift the rating the most.

About home Energy Rating assessments

Find out how your home rates.

A home energy rating for an existing home is done under NatHERS, the Nationwide House Energy Rating Scheme. An assessor visits, measures the house and models how much energy it would need to stay comfortable, then gives it a star rating.

The more stars, the less heating and cooling the home is likely to need. The report can also show how upgrades like insulation or better windows would change the rating.

Worth knowing

A rating models the building itself, not how you use it. Two families in the same house will still have different bills.
