Home Energy Audit Examples from Newtown

  • Open Energy has received a grant from Arwain www.arwain.wales which has funded 5 home audits in typical Newtown properties. Arwain is the Leader programme in Powys.

The purpose of this is to make these available to people who might live in similar properties in Newtown who might learn quite a lot by reading an audit of a similar type of property. If you live in a house of similar age and construction, some of the recommendations would equally apply to your home.

In addition, these reports would give you some idea of the type of advice that you would receive if you commissioned a bespoke report for your own property. We would recommend getting your own bespoke report if you are considering investing significantly in making your home more energy-efficient.
