Regular boilers are very, well, regular across manufacturers. Most boiler manufacturers produce one or two models of regular boilers with outputs between 12kW and 40kW and everything in-between. Unlike combi and system boilers, there is not such a great disparity between prices at the lower and upper ends.

We have identified ‘best buys’ in each size group. These reflect an all-round great package. We have also highlighted best performance boilers, which are not necessarily the cheapest but offer great efficiencies and warranties.
