Why upgrade to a Grant oil-fired boiler?

For the past 40 years Grant has developed some of the most innovative and efficient oil-fired boilers in the UK and Ireland.  Utilising our patented Vortex stainless steel secondary heat exchanger, Grant boilers are designed and manufactured to the highest standards so you can be confident in their durability and efficiency.  We believe in simplicity, and while our technology is advanced, our boilers are low maintenance and easy to install. And with over 60 models and hundreds of different EZ-Fit flue combinations there's sure to be a solution that's right for you.

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%
