“Excellent service. Arrived on time. gave best quote and completed job.”

Jane Elliott, SE24

“The work was done quickly and efficiently, and very neatly, I have already used them again to box in my boiler pipes and will use them again in the future.”

Hannah Izbicki, SW4

“On meeting Andy my immediate reaction was professionalism and honesty. The details of the quote were extremely comprehensive and clear. No hidden costs and his team knew exactly what they were doing. Good luck to him, his team and future in the Heating Engineering business. I strongly recommend a visit from him.”

Jamie Myalm, SE5

“Andy gave me a very competitive quote and was able to start work in the same week. As well as replacing the boiler he fi xed other odd plumbing jobs that I needed done too. His partner came back to replace my shower and did a good job of that at a competitive rate. Will be recommending to my friends and happy to talk to any prospective customers.”

Balraj Chauhan, SW4

“Job very well done with the least amount of disruption & a good price. Andy has a real cheerful manner and explains everything. More importantly actually turns up when he says he will! Would definitely use him again and would definitely recommend him.”

Mark Howells, SW17

“A new boiler install is not a cheap job but after receiving quite a few quotes Greenserve proved to be good value for money. The engineer was punctual and carried out a thoroughly professional job. I would highly recommend and would use them again.”

Kevin Board, SW11

“Andy was great – couldn’t have asked for a better company to do the job. Listened to what my requirements were, competitive pricing and good onsite manner. Definitely adding to my good tradesmen list.”

Replacement central heating system

“Andy and his team installed a whole new central heating system for us. They were very helpful, got the job done ahead of time and left the house so neat they could never have been there – except for the shiny new boiler and radiators which are now keeping us warm! What was particularly great was the time Andy spent understanding what we needed, advising us and giving us a detailed quote. When we added something to the spec he immediately revised it and sent it back so that we had an up to date version on record. All the paperwork has been very well managed and we just got our gas safe certificate through the post. The guys worked really hard and we couldn’t believe it when they finished two days early! I’d have no hesitation in recommending Andy to anyone, and it has been such a relief to have a stress and hassle free experience – we thought the job would be a real hassle and actually it has just been really simple. Thank you Andy!”

Installation of new gas boiler.

“I would strongly recommend Andy Harris and Greenserve to anyone looking for a high-quality, fast and reliable boiler installation at a keen price. Once he’d seen the job, Andy quickly provided a detailed quote with an itemised menu of optional additions to the basic installation, carefully explaining his recommendations in easily understood terms and he responded very promptly to my many questions. A key advantage he had over other installers was the ability to offer a 5-year manufacturer’s warranty on the Vaillant boiler we wanted. As a result we were quickly able to decide the details and settle a date. Since we wanted the installation completed in one day, Andy and his team turned up promptly at 7.45am to start the job, worked quickly and effi ciently right through the day to fi nish just after 8pm with a minimum of fuss and disruption and no nasty surprises. And in the following days he was happy to return and deal with the few but inevitable teething issues as the new system bedded in. The new boiler has been installed very neatly and is working well and we have the peace of mind provided by a 5-year parts and labour warranty. Can’t see what more you can ask of a tradesman: we would certainly use Greenserve for any future gas or plumbing work.”
