From 6th April 2018 the legislation around heating manufacture and installation in the UK is forging ahead with changes, are you armed with the correct information to pass onto potential customers?

These big changes to legislation have been named ‘Boiler Plus’ and are being introduced by the Department for Business, Energy and Industrial Strategy (BEIS).

In short, the bar has been raised significantly for energy efficiency of heating systems for both manufacturers and installers.

1) Gas boiler performance and space heating efficiency of the new boiler should be no less than ErP 92%.

2) Time and temperature controls are required for all gas and oil boiler installations.

3) Every installation must also include one additional energy saving measure. With the following options given to your clients/ homeowners to choose from, including any possible extra costs that may be incurred:


This system reuses the heat that would otherwise be lost and wasted from from the system. Some studies have shown that this system, whilst delivering the same amount of heat, is able to do so while using up to 4% less gas. In many cases this choice will be built into the boiler, so should not incur any additional charges.


This adjusts the radiators temperatures to be hotter when your home is cold, and cooler when your house is closer to your selected temperature. These controls should be around £20-30 more than standard thermostat. These can provide significant savings when used in the right circumstance. If you are the type of person that leaves your heating on all of the time, this could work particularly well for you.


Similar to the to the load compensating thermostat, but they adjust your radiator temperature according to the outside temperature. The controls are again £20-30 more. that the standard thermostat. If your bills are high and you have your heating on for long periods of time, you could make significant savings.


These thermostats allow you to control your heating through a smartphone or tablet, even when your not at home. There isn’t much research to suggest that smart meters save you money. However they will appeal to you if you would like to instantly check your home temperature and make adjustments.

The most notable change applies to the minimum performance standard for domestic gas boilers in England. The minimum efficiency level of all boilers manufactured and installed will be set ar 92% ErP.

The main motivation behind this change is to phase out inefficient boilers and reduce carbon missions in line with targets set by the EU. It forms just part of a wider plan known as the government’s Clean Growth Strategy which aims to combat climate change and provide UK homes with greater comfort and lower energy bills

Why are these changes being introduced?

This legislation is designed to help the UK meet the targets by 2020. More than £2.5 billion of Government funding was designated towards lowering carbon emissions for the period 2015 – 2021.

“This Government has put clean growth at the heart of its Industrial Strategy to increase productivity, boost people’s earning power and ensure Britain continues to lead the world in efforts to tackle climate change. Greg Clark, Business and Energy Secretary.

What if homeowners or installers don’t comply?

Installers who fail to install boilers in line with these new Building Regulations will be breaking the law and could be prosecuted by Building Control. The Gas Safe Register can also refer safety concerns to the HSE (Health and Safety Executive). Invoicing a customer for work which they claim to be legal but is not is also to be considered fraudulent under Trading Standards.

Homeowners who knowingly allow non-compliant work to be carried out could also face prosecution and fines of up to £5,000.
