Why choose Grant for your oil boiler?

Grant want to provide homeowners with peace of mind when they are upgrading their oil heating system and only invite heating engineers who are deemed as reputable, quality conscious and representing value for money.

Consumer group Which? have published the results of their 2019 oil boiler survey. Amongst the range of products to receive Which? Best Buys this year are all of Grant’s Vortex Pro Utility oil boilers. This is the third year running that Grant boilers have achieved this accolade making them the only oil boiler brand to be awarded Which? Best Buys in 2017, 2018 and 2019.

Grant check the installer’s OFTEC accreditation on a regular basis. However they always recommend to homeowners that they verify a heating company’s membership status with the awarding bodies directly via their relevant websites.

Award Winning Oil Boilers

Award winning Grant Vortex condensing boiler range, available in outputs from 12-70kW. Endorsed by the Energy Savings Trust, the appliances are currently some of the most efficient oil-fired boilers on the market.

Why Do I Need a Heating & Hot Water Installer?

Due to the complexity of modern heating systems, installation, service or repair work should only be undertaken by a qualified heating engineer.

This is why most manufacturers of heating and hot water appliances such as boilers, solar thermal and heat pumps only supply through trade merchants, rather than directly to end users.
