Grant Engineering (uk) Ltd

I have a Grant filter which is slightly leaking. Plumber wanted to charge me £340 to supply and fit the filter. I contacted Grant and they sent me a 'service kit' with spare washers and fittings.....all Free of charge. Great service and saved me a shed load of Dosh!! Thank you Grant UK.

As an Oftec registered engineer I always specify Grant oil boilers and have done so for many years, I even installed one in my own home. All in all they are a great company with great products. Highly reccomended.

I have been fitting Grant products for a number of years and have always found them to be really helpful - in paticular John Morris & Rob Dyer are always at hand whenever needed to help with any issues, they always listen to the installer and are willing to adapt new products to help make installation & design easier for installers. A breath of fresh air in an industry where installers aren't being listened to.

Absolutely terrible product and company. We had a Grant VortexBlue internal condensing oil burner with a Riello burner box fitted a year and a half ago. It failed in October last year. After countless phone calls to the service desk and five engineer visits, Grant finally changed the burner box. Prior to this they had changed most of the rest of the parts in the boiler, some of which were defective. Now in February 2023, the boiler has failed again and we are back where we were last October and I really can’t face the thought of going through that same process to ‘fix’ the fault again. We’ll probably just go for a replacement boiler, but I don’t expect Grant to refund the one we have (I’ll update if they do). I’m taking the time to write this so others can avoid the frustration we have experienced with Grant. They may once have had solid and reliable products but not the case with what we bought. Even our installers who are Grant accredited have acknowledged serious issues with this boiler. I recommend you look elsewhere.

We had a grant pellet boiler installed and it has performed terribly. We have spent a lot on maintenance over the last 7 years. We had a 2 year warranty and it was fine for that time. This year, for example, we had a full service in May and then it broke down in October and still isn't fixed now, so we had a whole winter with heating that we had to manually top up every day. I keep asking for a discount on our latest bill but just keep getting told that I am out of warranty so therefore just have to pay the bills. I suspect we will have to remove the boiler and install a new one. Boilers should last more than 5 years!!
