About Us


Started by DEA, John Denby in August 2007 (the date of EPC implementation) and based Energy Efficiency in Lowestoft, Suffolk, Britain's most easterly town, we have built a reputation for a friendly, fast and reliable service while at the same time giving excellent value for money. We are the HIP and/or EPC provider for prominent local solicitors, letting agents and estate agents, including Norton Peskett, Lucas & Wyllys, Christie & Co, Elizabeth Holdings, One Estates, Evenbrook Retirement Homes, Linburn Properties & Homes.

We understand the meaning of customer satisfaction and value for money and are constantly striving to improve our service either by flexible appointments or speed of issuing the end product. When we decided to introduce the 24 hour guarantee we realised that many Estate Agents would see the benefit this brings to help secure that all important new listing. Because of this we are limited in the number of Domestic Energy Assessments we can do in a day but if we accept the instruction then the EPC WILL be ready within 24 hours of visiting the property.


Trained and qualified to diploma Level 3 in Domestic Energy Assessing and Level 4 in Commercial Energy Assessing you can be sure you will get a first class and thoroughly professional service from us.
