Grant UK レビュー 

ASHP - something went wrong with the installation with a recommended supplier. The unit makes a loud 200hz drone that penetrates neighbouring properties.

The senior technical expert for Grant UK promised to resolve. After months of waiting he made one visit and fitted some sound insulation. This supposedly reduces the noise by 25%. It has made no difference. I wish the unit had never been installed.

It has made little difference and the underlying fault remains. Grant UK have done a drive by botch job and now say the matter is resolved.

Work was carried out very well and affistiantly left site clean and tidy

Brilliant reliable boiler fitted professionally

If you want an Air Source Heat Pump system, look no further than Grant UK.
A family run Company with five star Customer Service, available by phone or email.
Paul, the Technical Support Manager dealt with our issue sympathetically and efficiently, his outstanding product knowledge should be commended.
If we could rate Grant UK with ten stars, we would!

Went for an outside boiler in a weatherproof insulated cabinet to make things easier and free up the space where old boiler was located. Very neat unit and works extremely well. Engineer was quick to install and commission due to the way it arrived. Quiet in operation so couldn't ask for more. No feedback on oil consumption as it is early days but seems to be using a bit less, the house is warmer for it. Not the cheapest boiler but advised by our heating engineer to pay a bit more for a better product in his experience and opinion.

Has spoken to technical services at Grant a couple of times since the installation, can't fault it.
Technical assistance is important with something of such an advanced nature.

I would not recommend Grant heat pumps.

My house had a Grant Aerona 3 heat pump installed when newly built less than 7 years ago.

After 3 years, the PCB stopped working and had to be replaced.

Now in the coldest month, January 2025, the heat pump has stopped working again.
So no heating or hot water!

Plus, my engineer says that he has a problem getting a replacement part, as Grant will not sell it to him direct, but only through specified merchants.

It now transpires that there is a shortage of these parts, so no heating or or hot water throughout January.

3 PCB boards, and possibly a new compressor as well, within 7 years is not a great advert for a reliable heat pump from Grant.

Plus, absolutely no help or solution from their customer support line - basically "It’s out of warranty, so tough’”.

Also, when I said to their technical services help line that heat pumps are promoted as being a reliable product with a life expectancy of at least 10 years or more, with the Government pushing us that way for environmental reasons, Grant stated that we have never said that length of time about our products.

Heat pumps are costly and obviously from Grant not reliable over a longer time than any conventional gas boiler.

its only been a short whil

Supplied and fitted very professionally with little mess unit seems to be working fine

I was assured that my Grant Vortex oil fired combi boiler was top quality and would last many years. Unfortunately it has just sprung a water leak after only 7 years service and flooded the unit. Compared to the previous boiler I had which lasted more than 25 years I feel that modern boilers are not built to last. I wonder what other people think of the longevity of these boilers. So I have now been without heating for a week and the new boiler (not a Grant) will not be installed until the end of the month. The Grant was serviced by Certas every year ... Very disappointing and expensive.

We had an air source heat pump failure on Friday and were promised a call back (Friday pm). No one from Grant called me.

The claim details Ref G165216 - Service request no.165216 were made by our installer Warmaway in Dewsbury.

We need the parts immediately - we have had no heat or hot water in the house since Friday.

Here in North Wales over the past few days, there has been a major water leak and over 50,000 houses are without water.
As I had an Air source heat pump and water cylinder installed and manufactured by Grant UK, I was uncertain to put my heating on.

I spoke with Luke from the technical team, and he guided me step by step over the phone to turn the hot water off so I could have heating. An absolute legend and very helpful.

Following the installation of my Grant Vortex Pro 15/26 Boiler on 20 Dec 24, I contacted Grant Customer Services a week ago and asked for confirmation that my extended guarantee (2yr guarantee extended by 3 yrs to 5 yrs) had been registered. I advised that I had paid £220 on 6 Jan 25 via Pay Pal but had never received any confirmation of my new guarantee. To date I have had no email/postal confirmation of my guarantee extension, despite confirming my email address to Customer Services. Grant really needs to improve its Extended Guarantee Process and Customer Services needs to provide me with the necessary documentation.

I had a fault on a relatively new boiler which I had fixed independently. Following contact with Grant UK they very kindly offered to reimburse me for the repair work. I cannot fault their customer service, which was impeccable.

After using my Grant Aerona3 for six months my views are still 50:50 about it, hence 3 stars. It worked well in the summer, and generally works ok in the winter, which is helped by having a highly insulated house with underfloor heating throughout. But during cold snaps, performance has been disappointing at times. When the weather was -1 to -3 recently, it cost a huge amount of money to run and for most of the time didn't produce heat above 25C hence the hot water had to be further boosted by the immersion heater. Also the controls are a little primitive compared to other brands on the market, giving the end user very little awareness of how the system is performing.

Ashp - heats house fine when it's mild outside very poor performance when temperatures are below 5 degrees avoid them

Cannot praise Grant Technical Support highly enough. I rang them as we were having some challenges with our Air Source Heat Pump. Got through on the telephone easily and Damon quickly identified the problem with our settings. He patiently talked me through making a couple of changes which improved the performance of our system.

Works great when it is hot. Now that it’s 0, 1oC it’s fairly useless. Heating has been going 4 hours and it can’t increase the temperature of the bottom half of house by 1oC. Great product for Spain, Australia

I am a homeowner and purchased a Grants oil boiler 2years ago and I am extremely impressed with their technical support team especially Josh and Lance.
In conversation with either of these guys they explained everything in detail with the issue I had and resolved matters by replacement items sent very promptly even though my warranty had expired by 1 month, I can’t thank them enough and appreciate the efforts they went to to help a customer in distress especially at this time of year and in the wintertime conditions were are experiencing at present.
Once again a great big 👍 to these 2 guys
