“Over the last 5 years I have installed over 127 Grant Vortex boilers and I have never had a call out on any of these boilers, the product is 1st class, it is the only oil boiler that I recommend to householders to install.  Grant boilers are trouble free and the best product in every way, the customer service from the Technical Department is 100%.”

“Just a big thanks for pulling out all stops at 2pm on a Friday for Middleton Park Hotel.  As you know, their main boiler failed and the hotel & spa had no hot water. Boilers arrived at 9pm and we’re live by 3am. 10 Grant Vortex Boilers Modules now power the hotel while they wait for new boiler. Great job! Thanks again”

“Very pleased with the product. It looks superb. Looking forward to building sales on these now. Thank you for all your hard work you must be so pleased with the end result”

“Four years ago this month we had a Grant Condensing boiler installed in our house.  The difference it has made is really fantastic.  Not only have we saved money on heating oil, the three zone system is much more convenient and the boiler itself is much cleaner and quieter than what we had before.  My wife keeps telling me that it does exactly what you say it does on your radio ad.”

John KeaneHomeowner

“Just wanted to say a word of thanks for Grants hospitality and professionalism. The shear size ,future investment and history of excellence  of Grant is there to be shown to all. We are very impressed with the structure of the course and of Keith’s in depth knowledge and great personality. Speaking for our family of plumbers we will definitely be recommending even more of your products that we were unaware of and experiencing your after care is also a bonus that can be a seller to customers.

We wish you all the success for the future.”
