Boiler Plus for installers

What is Boiler Plus?

Boiler Plus is government legislation which ensures that homes in the UK have efficient heating systems. Since 6 April 2018, all new boiler installations require a minimum ErP efficiency of 92% and have time and temperature controls fitted.

Also combi boilers, the most popular boiler type in the market require one of four additional requirements. Each will need to suit each individual homeowners circumstances. It means each installation will include an aspect of consultancy as you discuss the best needs for the customer. The measures available are:

  • Load compensation - the ability to use the current room temperature to modulate the flow temperature from the, this needs the control and boiler to intelligently communicate.
  • Weather compensation - the ability to use outdoor sensors to find out the outside temperature to modulate the flow temperature from the boiler.
  • Smart control - A control that provides automated heating, hot water and optimised boiler efficiency.
  • FGHR (Flue Gas Heat Recovery) - This process redirects gases that escape the flue back into the boiler to preheat the water.

From the feature-rich MiGo personal heating assistant to the very simple and cost-effective Climastat room stat for the very simplest way to comply, Glow-worm offers a wide range of intelligent and easy to use solutions to Boiler Plus.

Boiler Plus in Scotland and Wales

Please note:

As of late 2022, Boiler Plus standards have been introduced in Scotland and Wales with some slight differences to those set in England.

Boiler Plus in Wales

Boiler Plus policy in Wales includes the requirement for the smart thermostat to also feature remote access.

For a complete solution that meets the 4 additional measures of Boiler Plus in Wales, we would recommend pairing the boiler either the MiGo weather compensated smart control, or the MiSET load compensated control.

Boiler Plus in Scotland

Boiler Plus policy in Scotland meanwhile has been expanded to apply to all gas boiler replacements (so includes System and Open Vent boilers as well as Combi).

Controls requirements remain the same as England.
