Avoid this horrible company at all costs they have ruined our peace! They installed a new boiler which was ok. They did the insulation which they messed up and had to come 3 times to sort.They also installed fans which dont bloody work! They ones we had before were perfect but they recommended we change them to the ones they had. Thought finally jobs done. But no! They dont leave you alone! Every couple of weeks they want to come and take pictures, then they want to see the boiler then its checking the insulation again and again! I have never come across any company that does this many check ups! It's disgusting!!! Please Avoid

Worst customer service I have ever experienced. They removed and effectively destroyed our perfectly working bathroom extractor fan and replaced it with one that was completely unsuitable. The new fan is only designed for short ducting, yet they installed it into our existing ducting without concern for performance. As a result, the bathroom ventilation is now far worse than before, with humidity not being extracted properly at all. What makes this even more unacceptable is the complete lack of aftercare. I contacted the company immediately by phone and message, but received no response whatsoever. Extremely unprofessional service. I would not recommend this company.

We had ZOA Energy oversee work done on our property through a government ECO grant to have air pump solar heating installed. They subcontracted it to Ecobuild contractors and the unfinished work done is actively damaging our property. Communication is almost non-existent. When they or the subcontractor(s) used to contact us it was always from personal mobile numbers and we was told not to phone the other numbers. We keep attempting contact only to be told they will get back to us. Window sills are falling off, gutter is sagging, neighbours gutter has been affected and leaking, extractor fans are ineffective and are not insulated on a cavity wall causing horrific damp and condensation, The walls are dripping with water mould now growing and parts they've installed are falling off the house. They denied we was with them initially only to confirm they had subcontracted it later in the phone call. They got as far as external wall insulation. job is not complete and this has been going on for around 2 years now with no end in sight. I cannot stress how bad this company is.

Where to begin what an absolute nightmare from start to finish avoid at all costs from the initial installation where they said they would be at my house for 3pm not arriving me chasing them to say they would be at my house at 7pm and then not turning up until 8am the next day with no prior warning. Entered bedrooms without knocking left rubbish in my front garden for weeks I had to make continuous calls to chase them to be left with no heating working as they didn’t check they had to come back and flush the system and wanted to charge me then weeks later they said the vents were wrong and they came back to do terrible work and the guy went into my garage and broke the door which they are refusing to pay for saying it is wear and tear but like I said if I broke it I would fix it but they refused to pay AVOID at all cost More lies in the response your technician did break the garage and if I broke something I would fix it as for the shoddy work no one has been in contact as your way is for the customer to continuously chase I have gone to the gas safety to investigate now as it’s a disgrace how you treat people I have pictures of everything including damage carpets in landing hopefully you don’t get more customers to treat like this I’m taking things further the legal way as you just have excuses absolute waste of time And the fan in the downstairs is connected to the light switch which fuses the electrics brilliant work total incompetency
