Retrofit regulations

Contractor Accreditations:

PAS 2035 and 2030

  • In the past there has been no blanket standards for delivery of domestic retrofit, as a result the Government created the PAS standard
  • From June 2021 compliance with PAS 2035 and 2030 is mandatory for all companies installing Energy Efficiency Measures (EEMs)
  • PAS 2035 is the overarching process that makes sure the whole retrofit project is overseen by a ‘Retrofit Coordinator’ who will take overall responsibility for the project
  • PAS 2035 is to be used in line with PAS 2030:2019 which sets out the standards required for the trades people that install and handover the retrofit measures
  • This will ensure that all of the trades people involved will be certified to a high standard and that the work will be independently checked at the end of the project

TrustMark

It is recommended that all retrofit work is carried out by TrustMark registered installers. This is the only Government endorsed quality scheme for work carried out around your home.

Microgeneration Certification Scheme (MCS)

  • This is a quality mark that covers all low carbon technologies and contractors
  • If you are looking to install technology, such as heat pumps and solar panels, ensure that the product and installer are MCS certified
  • You can find accredited products and contractors here: https://mcscertified.com/

Minimum Energy Efficiency Standard (MEES)

  • All private rental properties should have an energy performance certificate rating of “E” or above unless the property has an exemption
  • The government have proposed that by the end of 2028, all existing privately rented properties will need an Energy Performance Certificate rating of “C” or above
  • All new tenancies will need an energy performance certificate rating of "C" by as early as the end of 2025
  • Landlords will be exempt from this requirement if the costs to meet this standard exceed £10,000
  • Penalties, such as fines, can be given for rentals that do not meet this standard
  • Find out more information on these proposals and their progress through Parliament.

Gas Boiler ban:

The Government have proposed the following bans on gas boilers for domestic properties:

  • Gas boilers being installed in new build homes from 2025. New build properties will need to have a form of low carbon heating such as, a heat pump or electric storage heater. This ban is part of a piece of legislation called the "Future Homes Standard" which aims to ensure that all new build homes are ‘zero carbon ready’
  • Bans on replacing gas boilers in existing homes have been suggested. This will mean that if your gas boiler breaks, you will not be able to replace it with another. Instead you will need to install a low carbon alternative, such as a heat pump or electric storage heaters.  It is unclear when this may take effect, but the government have suggested between 2035-2040
