Messy and unfinished

Very unorganized. The guys that came seemed to be tripping over themselves, too many of them there at the same time and not enough space to do the jobs. They got loads of plaster all over my nice painted floorboards because they didn't put enough protection down. Some of my plugs never got wired back in after the insulation. The electrician was meant to come to do them but he never did. Some of the floorboards are very loose and haven't been properly screwed down after they put in the pipes for the central heating. I'm still waiting, three months later, for my MCS certificate for my solar panels to connect them to the grid. I've reminded them a couple of times but they still haven't sent them.

Mark and Craig came and insulated my property. They have done an amazing job, were polite, friendly and professional. The finish is perfect and I would strongly recommend Eco Giants for future works. I am truly happy, thank you.

Where do I start , they do what they want when they want no notice of the work starting or scaffolding going up even tho the First Lady that knocked on the door said oh no they don’t use scaffolding clearly doesn’t have a clue what she’s on about , then saying we need extractor fans in the bathroom and kitchen which they never said about also trickle Vents to the windows , then tried to tell me they did tell me about this ,this company is run by Mickey Mouse , when they finished there was many problems with the roof I found no reply to emails rubbish and bits of insulation everywhere ! Left the guttering filled with stones and dirt ,screws all over the garden literally and shocking company , no sign of any guarantee certificate avoid just a cash grab company fleecing the government

Great service from Brad Nick and Alex

Great service from Brad, Nick and Alex who spent 2 days on my property insulating the roof. They were respectful of my privacy and need to work from home during the whole build, made as little disruption as possible and have done a great job with how the roof looks.

Nick Brad and Alex completed our flat roof insulation quickly and efficiently. The team were personable and informative, sharing pictures as the work progressed. Additionally Danny and Leo did a great job of installing an extractor in the kitchen. Thanks guys.

AVOID AVOID AVOID

This company is utterly disgraceful. Eco Giants installed a warm flat roof last year to a set of five flats and from the day the work was carried out there have been nothing but problems which are currently still ongoing after almost a year! The result of their work has caused ceilings to collapse, financial loss, homes and businesses flooded and damage and disruption to the lives and homes of elderly and vulnerable people whose health and safety have been put dangerously at risk. The latest ceiling to incur damage through the ingress of water belongs to a 90 year old man, which shockingly revealed mould growing underneath, which also poses a worrying health risk. He is currently trying to manage the endless amount of leaks in his home after this company returned to finally remove the damaged warm roof and failed to ensure that the existing roof was watertight, not ideal when a storm has been forecast!!! The second home belongs to a single parent who woke up to find water running down her walls, near the electrics. This is certainly not what you would expect from a government funded scheme aimed towards making homes more energy efficient, instead the people affected have had to watch while their homes are literally being destroyed around them and their health and safety put at risk. I only wish I could post pictures to show the amount of damage that this company have caused to make others aware and to warn them to think twice about placing their trust in this company.

Eco giants did work in my flat this week. Dom, Nicki and Dec have done an excellent job, their work is thorough and professional. The insulation and plastering is spot on and they were happy to put in the time and work to get the job done right. A lot of care was taken when moving and covering furniture etc which is very much appreciated. They also cleaned up at the end of each day - top marks and no complaints!

Dom, Nicki and Dec

Dom, Nicki and Dec spent a week with me working on IWI measures (internal wall insulation) They are the most professional and hard working team i have ever experienced. I know what i am talking about as i have just renovated a house! They were here at the crack of dawn (6/7am) and left at 5/6pm and they didn't stop to get the job done as soon as possible for me. Really genuinely lovely people who take pride in their work. They cleaned up after each day and kept me updated on what would be happening and when. Such a professional set up. Everything was covered, and moved etc. I would 100% recommend Eco Giants. Thanks team, will hopefully work with you again!

New roof fitted by Nick and Brad

Just had a new roof fitted by Nick and Brad and I am absolutely chuffed to bits with the result! The lads attention to detail was unmatched, as was their professionalism. They were more than happy to answer all my questions and they cleared everything away when they were done. A real credit to the company!

⭐️⭐️⭐️⭐️⭐️ Outstanding Service

⭐️⭐️⭐️⭐️⭐️ Outstanding Service – A True Benchmark in Professionalism I cannot speak highly enough of Eco Giant and the exceptional service we received. From start to finish, the entire process was seamless, efficient, and delivered to the highest professional standards. A very special thank you must go to Dom, Nicky, and Dec, who truly went above and beyond in every aspect of their work. Their attention to detail, precision, and pride in delivering perfection was nothing short of remarkable. The team maintained a clean and tidy work environment throughout, and were always polite, approachable, and happy to answer any questions or concerns we had along the way. Their level of care and commitment is a rare find and speaks volumes about their character and work ethic. My partner, who has been renovating properties for over 20 years, was genuinely impressed—something that does not happen often! He could not believe the level of craftsmanship and professionalism demonstrated by the team. It was a true masterclass in how things should be done. Eco Giant is a shining example of excellence, and we are beyond grateful for the transformation they have brought to our lives. Thank you again, especially to Dom, Nicky, and Dec—you are a credit to your industry. Warm regards, Clare Pritchard

I would like to highly commend Nick and Brad for the brilliant job they have done insulating my roof. It was a more complex job than expected but they worked extremely hard to complete the job, we're very courteous and professional. Would also like to thank Jake at head office for keeping me updated on progress and arrangements made for work to be done, always very polite and helpful.

Jordan and Anthony delivered a professional reliable and tidy service. The insulation is like an internal winter coat polished off by glass like plaster improving the original aesthetic. I was also impressed by their kindness and customer service skills; they went the extra mile by assisting the delivery driver with offloading due to my poor health. Finally the said guys were also diplomatic after defusing my landlord by reassuring her that their work methods preparation and risk considerations were fully implanted to ensure a long lasting quality. I would recommend ‘Eco-Giant’ to my friends family and community since the whole treatment has been uplifting.
