Grant is the only oil boiler manufacturer to achieve Which? Best Buys for three years running

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.

The Which? Best Buy logo is widely recognised as an endorsement that reflects confidence, trust and reliability in products. The Which? Best Buys and the supporting surveys play an important role in the decision-making process for householders researching new appliances for their home. Grant Engineering is therefore thrilled to have the high-quality build of their Vortex Pro Utility models, for example, acknowledged in the latest Which? survey with Best Buy status.
