We are Energy Efficiency Specialists working domestically with ECO Funding and commercially through Landlords, Letting Agents, Country Estates and Housing Associations. With years of experience and expertise, you know you’re in good hands when you come to us.

Since establishing the company in 2009, we have gone from strength to strength. GHE started with just 4 family members in 2009 and now have 10 full time administration staff and many more installers and sub-contractors. We’ve installed more than 40,000 measures to date!

GHE are still wholly run and owned by the Davis family and we pride ourselves in our reliability, quality and integrity. With a large portfolio of both small and large scale customers, we know we do a good job. Our team provides trustworthy, no pressure, and honest service because experience has taught us that this is the only sustainable model for the long term.
