very rude individuals

very rude individuals; never want to take calls. three different people gave three different responses as to what was needed. they will only talk to agents and outlets who charge excessive mark up prices just to take delivery at their shop and then hand over to plumber. looking for a small additional unit for the last six months....... would not recomment to anyone.

Brand new boiler fitted moving into a brand new build house. Boiler pinholed 4 years into a 5 year warranty, even with annual servicing. I was told I had to get a replacement grant boiler for them to consider the warranty, following which they advised that they wouldn’t honour the warranty and that I would have to pay.

Four * for heat pump/2 * for customer serviceservice

After 3 years in new property, we had a problem with heat pump and sourced a local engineer to repair. After problems getting the replacement part leading to 3 weeks with unreliable heating when due to weather we needed if most, our engineer helpful negotiated a replacement heat pump under warrenty - so far, so good. Engineer said it would have a further 5 year warranty, but after several emails/phone calls and promise that someone would get back to me I've been unable to get confirmation our new heat pump has been registered (essential for warranty) and have not received any paperwork. Really, really disappointing and am left wondering what, if any warranty, I've got!!

Dreadful experience!

Dreadful experience!
I wanted to ask about a product that grants had for sale off their brochure, but whoever answered the call put me onto the wrong person , I think he was in technical, and this guy was so snotty and rude, even told me to go elsewhere, which I did eventually.
After that experience I don't recommend them at all, AVOID!!! At all cost!

Grant is the Worst company ever to deal with

Grant is the Worst company ever to deal with. My new Grant boiler blew a hole in my floor causing massive damage to my house due to Grants faulty boiler/incomplete manual with important safety & installation information missing from it, which has since been added to the newer version. They have been not engaged, don't want to know, blamed the installation despite an expert engineer reports proving it was not caused by installation and have not cooperated or contacted me or the supplier though it's a year since this happened, evidently Grant do not care at all about their customers. I tell everyone to avoid Grant & their terrible products & urge anyone reading this to do the same, they're the worst company to deal with if anything goes wrong.

Never again

Chose a grant over a Firebird oil boiler ...it cost me 7k ..now 11 months in it has stopped working .. typically when it's -2..
Engineer has said it's low oil pressure..so I have spent most of the afternoon /evening driving to the local garage filling Jerry cans and getting covered in oil pouring it in my tank because it's -2 and everyone wants oil...guess what ..still won't fire and now I'm covered in oil with no hot water ...no heating ...two octogenarians and a three week old in a freezing house in the middle of lockdown so can't even farm them out to warm households ...to say I'm disappointed is an understatement...AVOID

Excellent training facility and well engineered products

Went on three training courses in their training centre in Devizes, England. Excellent training facility and well engineered products. Staff are all very helpful and knowledgeable. Always a great experience with Grant. Going back for more training next month.

Left hand, right hand.

This is an interim rating at 5.30am while I control my emotions at the service received thus far; and that service is part of the reason I'm lying in bed awake concerned about my disabled-registered wife's health as we near our 6th day without a boiler. I will be happy to review and amend if and when appropriate.

Our boiler is regarded as 'new' by both plumbers I have so far asked to examine the boiler - one of them is the person who installed it in May 2018. Both plumbers diagnosed a 'serious fault' requiring a major component replacement.

We returned home from holiday on Wed 4th March 2020 to a very cold house and a boiler which would not work. First plumber attended on Thurs evening, 5th March. He diagnosed the fault, gave an estimate for repairs and was very helpful. Because of the high estimated cost of repair I thought I should contact Grant re warranty cover.

Fri morning, 6th March, I rang Grant UK because we live in Northern Ireland. I was informed that the boiler was still within its (two-year) warranty but that I would have to go through Grant Ireland. That makes sense geographically, but anyone who has lived on these islands through the past three Brexit-dominated years will know that, in this respect, Ireland is a completely different country to the UK.

I rang Grant Ireland. The person I spoke to was astonished at the plumber's diagnosis of the boiler, was loathe to believe it and suggested it was something very simple. He took my details to pass on to the person who covers 'my area' i.e. this part of the UK, and who, it appears, trades under Grant NI.

I mentioned my wife's health issues and requested that he asked the person who covers my area (and who lives relatively close to us) to expedite the case as it was the end of the week. He agreed and told me I would get a phone-call. I didn't. I waited several hours.

I again called Grant Ireland and was given the name and mobile number of the man who 'covers my area'. I rang the man's number many times and got no answer. In exasperation as the afternoon wore on I left a message citing the urgency in needing to speak with him. He called me.

This man, whom Grant Ireland told me covered my area, denied that responsibility and said he would nevertheless help me get the right person to fix the boiler at my expense. I asked about the warranty - he said because it was supplied by Grant Ireland it was a one-year warranty; of course now expired. I told him Grant UK advised me it was a two-year warranty, his retort was that the boiler was supplied by Grant Ireland.

The most important thing was, and remains, getting the boiler working so I asked him to please go ahead and get someone to sort it out. I asked him if he would call back to let me know what was going to happen, and when. He assured me he would. He didn't and hasn't.

Unable to sleep, I have examined the different Grant websites. The Grant UK site states our boiler has a five-year warranty - despite the customer service people saying on the phone it is a two-year warranty. The Grant Ireland website lists the warranty as one-year. I live in the UK.

However, that all seems to be academic as no-one within Grant - UK or Ireland - appears to want to accept responsibility. Meanwhile, part of our home is warming thanks to continual burning of wood in a multi-fuel stove, and part of the house remains at 12 degrees C; and that is detrimental to my wife's poor health.

I now have to wait until Mon morning when I will attempt once again to get some immediate action from Grant.

UPDATE: 24 hours after contacting Grant Ireland, people there - whom I had not previously been in contact with - quietly, competently and immediately set about rectifying the defective boiler. The plumber they arranged to carry out the work this morning was superb in every way and the situation has been sorted out to my complete satisfaction.

The problems and unsatisfactory service I experienced at the outset were from a person outside Grant Ireland with less ability and customer-focused aptitude than his position would lead one to expect. It happens, that's life.

Bottom line is I am completely satisfied with the response from Grant Ireland with many thanks to AL in Customer Services who shows how the job should be done. I am happy to change my experience rating in lieu of this from 🌟 to five 🌟 🌟 🌟 🌟 🌟

Reply from Grant Engineering Ireland

Hi Mr Elliott,

Thank you for your review and we are sorry to hear of the problems you’ve been experiencing. Although Northern Ireland is in the UK, the area is not covered under Grant UK’s territories, which is why you were referred to Grant Engineering Ireland. The products and warranties available are different between the businesses and we apologise that this was not made clear to you over the phone. We can confirm that your enquiry is being dealt with and that our Customer Services have been in touch with you this morning, we endeavour to resolve any issues as quickly as possible to reduce the down time and inconvenience to our customers.

Kind regards,

Grant Engineering

AVOID LIKE THE PLAGUE !

Avoid like the plague. I also thought Grant boilers were fantastic. Newsflash.... They are NOT. Water burst through steel wall and into pump after few months of fitting. They refused to replace. Guys there pig ignorant. They then tried to blame my professional plumber who installed 30+ of these boilers. He said an absolute disgrace they tried to shift the blame.
Avoid this company. I installed Firebird and much better engineered. No issues with Firebird
