Avoid this Company like the plague! They have provided terrible support and service to me over the past two years and I think their practices is suspect to say the least. They are not who they appear to be. Caveat Emptor. They provided and installed a replacement boiler in June 2021. In November 2023 I reported a fault to Glow Green - the boiler kept cutting out. Following a long exchange of e-mails and a visit from a Worcester Bosch Engineer on 16th December 2023 it was determined by him that the boiler had been installed with the water flow and return connected the wrong way round i.e. incorrectly, causing the flow and return sensors to work incorrectly and hence the cutting out. Glow Green had also supplied and installed a Magna Gas Flow filter but because of the installation error it is connected to the wrong flow pipe. To date this fault has not been corrected despite numerous e-mails, phon calls. Glow Green did not believe the Worcester Bosch report so subsequently agreed to send their own engineer to verify the fault which they did on 12th January 2024. I have repeatedly written to them by e-mail requesting their action to correct this fault but I have received no acknowledgement or offer of help. On 17th February I wrote to their Director Mr. C. Wigoder and asked him to intercede on my behalf but have not received an acknowledgement or any offer from Glow Green to rectify this error. I have now had to refer the issue to the industry ombudsman who is pursuing my case on my behalf. When I phoned Worcester Bosch to request details of their warranty they confirmed that Glow Green is not an accredited Worcester Bosch installer, shocking when you consider the wording on the website: "Expertly trained staff Nobody knows a Worcester Bosch boiler like an accredited installer does – our staff have gone through all the relevant Gas Safe, OFTEC and/or MCS approval. What’s more, they have experience of installing and servicing hundreds of Worcester Bosch boilers under their belts so you get efficient service. The safety of our customers is paramount." However, I now question whether they have any direct employees as they appear to use sub-contract gas installers who apply by mobile app and are constantly canvassing for sub-contractors to join their "network of installers" through a mobile phone portal.

I doubt that this company will be in business in five years so any warranty promises or offers made are meaningless. Based on my own experience with this company I would recommend that you DO NOT GIVE THEM YOUR BUSINESS.
