Insite Energy Reviews 

Reese came to run the anual tests for our heating unit! He was very friendly and helpful! We look forward to see him again next year!

Darren came round to fix the leak in my HIU. He was great from the offset assuring me he would get it fixed. Which he has! He then took the time to show me that all my taps had hot water and that there was no more leaks. Great service 😃

Thank you Cohen for your perserverance in getting the issue sorted and the system reconnected.

Daren was kind and professional

I have been a customer with Insite Energy since moving into my flat in September 2025. For over a year, my online billing portal completely failed to work, and my GURU meter never updated.

Despite multiple complaints over the course of a full year, I was repeatedly told the exact same line: that they were "working on it." Unsurprisingly, nothing ever changed.

Then, at the end of August 2026, my account suddenly started working again out of nowhere, promptly followed by a £450 back-billed debt for energy I had no way of tracking or paying for in real-time.

To be entirely fair, I am more than happy to pay for the actual energy I consumed. However, being slapped with a massive lump sum due to their systemic IT failures is completely unacceptable - especially given the steep daily standing charges we are forced to pay for a system that clearly lacks proper maintenance and upkeep.
When I requested compensation for this ordeal, the customer service experience went from bad to worse. I’ve had to call three separate times, only to be passed around with empty promises that "someone will call you back" - a call that never comes.

I have now submitted a formal complaint specifically regarding compensation, but getting a straight answer feels impossible.

I move out of this flat at the end of September and will finally be free of Insite Energy. I genuinely cannot wait to leave them behind.

If someone from Insite would like to get in touch with me directly to resolve this, I would be more than happy to discuss it.

Engineer was quick efficient very pleasant and fixed my issue with the meter. Thank you Darren!

Lirim and Adam are very kindly . they do well for everything.

Thank you, Darren and Reece, for providing an excellent servicing and explaining how to switch on and off the heating system. They were punctual, friendly and nice. Now I'm all ready for the colder season. Thank you again!

They rob you blind. Prepaid system with no choice of supplier keeping you captive. Standing charge alone is £50 per month! Up 15% in under two years in our development. Now multiply that across 300 flats... scandalous. No oversight and no Ofgem protection. System so interdependent that one resident fiddling with their unit a bit too much affects everyone else’s. No energy saving mechanism in place and no cooling system in the summer. We lost count of the number of times their online portal doesn’t work leaving residents with no hot water or heating in a limbo trying to top up. So all in all, a pretty dire product and services which they charge us £200k plus a year for. Yet, they have the audacity to get their maintenance team to push for positive reviews on this platform in return for one pound a review… Justifications that wouldn’t survive five minutes of scrutiny. This should be illegal.

Lirim Seci great customer service!

Had a great experience with Lirim servicing my boiler. He was knowledgeable, professional and took the time to explain how to keep my underfloor heating running smoothly. He also gave me some really helpful advice.

Lirim Seci and Adam Ayzel They were very helpful and professional. They checked everything thoroughly, explained everything clearly, and answered all our questions. We really appreciated their help.

Lirin seci and Adam ayzal did a great job at cerulean house very professional thank you

Cohen was very friendly and helpful he provided a great service.

Luke and Daniel were great and very efficient about fixing out hot water - we had a great experience!

Had a HIU/ Smart meter system repair/maintenance scheduled planned with the team.

The scheduling was very smooth with the planning team and then the actual visit was also super smooth.

The engineers, ie., Luke and Daniel, showed up exactly at the scheduled time and were super efficient and independent in completing the part replacement and informing the household about the changes/repair.

Peter was excellent and efficient he solved my leak. Thanks again.

Darren the engineer fixed the issue in minutes. He was quick and efficient, explained what happened, and solved the problem. Great guy and great work.

Lovely person, very polite and respectful. Did everything for the service and showed me how to turn on my heating. Would recommend Darren!
