Just wanted to say thank you for all your efforts in securing a Grant to upgrade our heating system and carrying out the work.

A credit to Happy Energy as is Karla who was great. Thank you all.

Just to say a really big thank you to Happy Energy and their great team of workmen. We have heating for the first time in nearly 12 years!!

- Mr and Mrs Lane – Central Heating installation – Cornwall

I am writing to thank you for installing my central heating. It works fantastically. I would also like to praise the engineers who installed it. I must confess I was not looking forward to the work being done but the team you sent made it an absolute pleasure.

I was consulted on every aspect, they really went the extra mile to cause as little disruption as possible and cleared up every day. I felt utter trust in their reliability, trustworthiness and technical skill.

Cannot praise the workmanship and consideration of your team enough. I would recommend your company to anyone thinking of having central heating fitted most highly.

- Suzi – Central Heating Installation – Newlyn

Customer service at every stop was excellent, from speaking to customer service on the phone, the person who visited to assess the suitability (who was extremely knowledgeable and helpful), to the person who visited to complete the finance application and the installers themselves were fantastic.

- Stephanie, Illogan

Just wanted to say thank you to everyone at Happy Energy for all their help and expertise regarding the installation of the boiler. What a good team of people you are.
