'Boiler Plus' standards to usher in more efficient domestic heating from April 2018

New standard will see minimum efficiency boiler standards and compulsory controls

One of the most significant announcements in the government’s Clean Growth strategy is the long-awaited launching of the minimum efficiency standards, which have generally been referred to as ’Boiler Plus’.

The move will see new standards written into the government’s Domestic Compliance Guide from April 2018.

The scheme is designed to encourage energy efficiency by mandating requirements for heating systems, setting out new expectations regarding what both manufacturers and installers have to deliver.

HHIC, which helped conceived the policy, said: ”Alongside a host of other measures [in the Strategy], this policy will require a new minimum performance standard for domestic gas boilers in English homes, set at 92% of ErP. The ErP Directive aims to phase out poorly performing products across a range of product groups to reduce carbon emissions across Europe, with the ultimate goal of achieving the EU’s 2020 targets.

The legislation will require all those fitting new combination boilers to include one of the following in their system:

  • Flue gas heat recovery systems
  • Weather compensation
  • Load compensation
  • Smart controls featuring automation and optimisation functions 

HHIC said: “The premise of the legislation is that it will encourage, and enable, householders to make informed decisions about the products that best meet their needs. The degree of flexibility in terms of which entities render a new boiler ‘compliant’ means that the diversity of the house stock and needs of the consumer are catered for.”
