Which? unveils an easier way to find a new boiler

New boiler reviews make comparing 180 boilers easy


Choosing a new boiler can be an intimidating and costly business – but our new and improved boilers review can help you find the best on the market for your home.

Our revamped boilers review has more models, more specification information and more ways to compare.

We’ve increased the number of boilers we cover from 49 to 184 gas and oil condensing boiler models, and for the first time have included all the models from the major gas and oil boiler manufacturers.

According to our boilers survey, these manufacturers – including Baxi, Glow-Worm, Worcester and Vaillant – produce the models owned by 85% of gas boiler owners and 66% of oil boiler owners.

Improved boiler reviews

Other key changes you’ll find include:

  • more than 40 Best Buy boilers to choose from.
  • nearly 40 new pieces of specification information to make it easier to compare boiler features.
  • 33 system boiler reviews have been included for the first time.
  • efficiency and claimed performance of each boiler directly compared against the figures for more than 200 other boilers.
  • more efficient boilers – all of the models we feature are efficient enough to be installed according to the 2010 Building Regulations.

Find the best boiler

We’ve also added new and improved ways of searching for boilers to our boilers comparison tool, so you can now filter by:

  • gas, oil or gas/LPG boilers.
  • heat outputs – helpful if you know what size boiler you are looking for.
  • boiler efficiency.
  • features including hidden controls, warranty period or central heating temperature control.

Plus you can find out how thousands of owners rate their existing boilers – including how reliable their boiler has been and how happy they are with the boiler brand they bought.
