Customer Testimonials

We are a customer-focused business, proud of our reputation for honesty & reliability.

Below are some of our recent testimonials from happy customers.

Three years ago I was about to spend over £10,000 on increasing the insulation on one of my properties in Watford in order to adhere to Minimum Energy Efficiency Standards (MEES) legislation. Simon happened to be in the area and said he would pop in that day as my builders were due to start work the next morning.

By the end of the day not only had Simon concluded that in fact the property would NOT reach an &; rating after adding the insulation, but came up with an alternative idea which ended up costing me £200, saving me a great deal of unnecessary work, time and money.

I have since used Simon and his team again on other projects and I can’t recommend them high enough.

Network Energy are a fantastic team to work with. They are prompt in arranging appointments with clients and completing EPCs.

Polite, professional, and prompt, an absolute pleasure to work with!


Samuel Dey, Dey, King & Haria Estate Agents

Having searched on GOV.UK for an EPC surveyor, we contacted Simon Coombs to carry out an EPC report on our commercial offices in Watford. Simon was able to attend our offices to carry out the survey and produce his recommendation report and EPC within the week, with the link to the EPC Register.

Simon was courteous and professional when moving around the office and provided us with a realistic timetable to get the job done. We would recommend his services.


Tara Dischamps, Collins Solicitors

At auction, we work to very tight timescales and rely on our suppliers to deliver. We use Simon for both domestic and commercial assessments because he’s professional and fast to respond.

I recommend him to clients and am happy to recommend him to you.

Being an estate agent we need to find a reliable EPC assessor. Network energy have been a pleasure to deal with. I have worked with Simon Coombs for the past 8 years. We have always find Simon to be punctual, efficient, polite and reliable. We always gets good comments from our vendors regarding Simons work.

He usually turns EPC's and floor plans around within 1-2 days sometimes even the same day.

Karen is always easy to contact if we need to re-arrange appointments.

I would have no hesitation recommending Network Energy.


Jason Cannon

Reached out to Simon to get a commercial and residential EPC done. He was prompt and efficient from the get go. We booked in a suitable time and everything was executed as planned. The property was some distance from where Simon is but it was a very smooth process. Turned around in 24 hours from site visit. Thank you again and will be using you for all up and coming jobs!
