Grant UK レビュー 

I have had nothing but trouble with my Grants oil boiler since it was installed. So I wrote a trustpilot review to warn others off making a similar, very costly mistake. Shortly after it was published Paul from Grants contacted me to listen to what has gone wrong. They then sent the wonderful Daniel out earlier this week who listened to all my gripes, spoke to the plumber who has been trying to resolve this for us, and spent ages checking things over and fixing things he thought could be causing the problems. He even bled all my radiators when he was finished as there was likely to be air in the system after all the work he had done.

The faults with the boiler are intermittent so I can't say it has definitely been fixed, but for customer service they deserve 5 stars. I will update the review when I know if all the problems have been solved, but for the moment I am absolutely delighted and have real faith this nightmare may be over.
----------------------------------------------------------
I I really can’t state strongly enough how bad my Grants oil fired boiler is. It’s been in for 7 years and it’s been 7 years of stress and hassle.

Grants the company did send someone to look at it about 3 years ago and said it was fine so from a customer service perspective they were good but from the perspective of manufacturing a boiler that does what it needs to do, they’ve not managed that.

It has been regularly serviced by a qualified engineer but it is a constant source of stress and we have to go outside to reset it at least once a week (sometimes once a day). I did lots of research before getting this new boiler fitted which makes this all the more disappointing.

The product is working well since it’s been installed but I wanted to write a review on the customer service. There was a small post installation issue and I spoke to the Grant Customer Service team to get an engineer out to fix under guarantee. Even though the fault wasn’t completely covered by the guarantee, they fixed it without charging me extra. You’ve won a loyal customer for life. Well down Grants

Only boiler that is reliable and simple , wouldn't buy anything else

The boiler has just been installed so we need to wait 10 years before I can give a sensible review, but both the installer and commissioning engineer speak well of the product.

Initially a very speedy attendance following my report of boiler water leak. Subsequent boiler replacement was completed following a power wash of pipework. Efficient and friendly guys Highly recommended.

Works well, online support very good

We have had the pleasure of knowing Carl and Ryan for some 10 years now and their work has always been exemplary, this installation was no exception their work was second to none.
I would like to publicly acknowledge the outstanding standard of their work.
A very satisfied customer.

Had a new Grant Vortex Boiler 46/70 kw installed by ATP Heating Services. Good job. Quietly and efficiently done. Boiler working well.

Great little boiler. Fits our back yard a treat and looks very smart. It’s very smooth and quiet and we like the fact it’s low nox.
Our cottage has now entered the 21st century with Bluetooth connection to the thermostat. We are now warm at last.

Grant Combi Blue Flame oil boiler faulty only 3 years old, has broken down again, we have not had any to water or central heating for about 2 weeks now, its had some new parts fitted but has an intermittent fault, you think your running a bath and when you get to it, the water is flat cold, its had a new oil pump on and coil and still not working, it won't fire up, you think you have a warm house to get up to, no your wrong, waiting for the plumber to come again, 4th time lucky we hope. I mentioned to the plumber that the heating takes ages to get warm when your trying to run a bath or shower, and he has just told me that with a combie boiler you can't have hot water and the heating on at the same time, it dosen't work like that, and when I am running the bath which takes 10 minutes if I want to use water anywhere else in the house, like clean my teeth or wash down the worktops there is NO WATER anywhere else in the house available, there is only two of us, but its a big house, I think we were miss- informed of the capabilities of a Combie boiler, it should be made clear on the brochures and information should be readily available of its limitations, I would not buy a combie boiler again. I am Very disappointed.

We’ve just had a new Grant oil fired Combi boiler fitted .
All I can say is it’s awesome!! lots of lovely hot water,great efficient heating .
Saves room in the kitchen as it’s an external model.

New Grant oil boiler installed today by GD Davis. Gary and Jordan worked hard and it was done nearly and well in a day. Nice well made boiler replacing another Grant 16 years old that had smelt of kero from day one and resisted every attempt to eliminate the smell. So hoping this one finally lays the pong to rest. It is producing hot water and operating normally.

I'm afraid that this is a repeat of my review of July 2023 as our Grant PCB has just failed for the fourth time since January 2020 - on each occasion leaving us without heating and hot water for up to one month (twice in mid Winter) and, eventually each time, with a very large bill for a replacement. These circuit boards seem to have a lifespan of around 15 months - even with regular servicing by Grants. As we live in North Northumberland, engineers experienced with ASHPs are few and far between. From my prolonged experience (shared by many of my neighbours and in new build houses designed and built for such a heating system) I would strongly counsel against replacing an existing system with a Grants ASHP.

Having had a grant oil boiler with very good reliability for the last 25 years I had no hesitation in having another one, very pleased with the installation done by a G1 fitter, B A Wallbridge, and so far pleased with our choice, a combi vortex pro external.

Brand new Boiler started to be very noisy after a couple of months.
1. Grants engineer- fitters haven’t fitted it correctly. You need a new expansion tank. Fitters fit new one at their cost.

Noise continues
Grants engineer- it’s the baffles they need replaced! Completed by grants.

Noise gets worse.

Grants engineers - boiler needs replaced!

Noise continues

Grants - your water is contaminated. It’s not covered under warranty. You need a new boiler.

Me- what about the expensive filter you charged £800 for?

Grants - warranty will be void. Contact the fitters!!

Fitters- nothing wrong with the fitting. The boiler is no use!

Me - looking to find £4000 for a new one. My pension is that good! I h
Guess I’ll spend the winter freezing. Thanks for nothing.

Good knowledgable engineer. Would've been 5 star but for a problem with the electrics which added cost to the job.

I want to thank Grant UK customer service, and in particular their representative who has dealt with my enquiry, for the most speedy, pro-active and helpful assistance that I've received from any company's customer service team for a very long time. It deserves to be given 6 stars, not just 5.

I had a problem that led to my central heating system cutting out while I was away from home during the very cold weather at the end of January, after storm Eowyn. The problem sorted itself out, but it was unclear whether the issue had been with the Drayton Wiser smart CH controls or with my Grant Vortex PRO Outdoor Condensing Combi 36 kW boiler itself.

Grant's representative helped immensely by identifiying for me the one (very obscure) reason that could have caused my CH system to cut out for over 4 hours, but then restart itself without any human intervention. This was not a fault of the Grant boiler itself (which has been 100% reliable for 5 years) but seems most likely to have been the result of my having failed to bleed air from the radiators sufficiently frequently.

So my grateful thanks to all at Grant UK.

New boiler came with 2 manufacturers faults. Rude customer service and not one apology for the faults and inconvenience of no hot water/heating during the coldest months of the year. The person sent out to fix it provided a very vague report for a third issue which wasn't boiler specific but barely any explanation was given and was followed by a big bill - they'd removed a filter but did not inform us that we'd need to put a new one in, we only found this out after phoning to query what was actually done - At very least they could have written this in the recommendations section provided at the bottom of the report. A very frustrating experience so far, no real customer care - I would not recommend to anyone considering a new boiler.

It has made a boiler that is really efficient and low cost to run. So happy with it so far.
