TrustMark & Government Programmes

TrustMark is the only Government Endorsed Quality scheme covering work a consumer chooses to have carried out in or around their home. 

To demonstrate compliance with the most up to date PAS standards and to ensure a sufficient consumer protection process and guarantees are in place, the following schemes and subsidies require a business to be registered with TrustMark. 

Energy Company Obligation (ECO)


The Electricity and Gas (Energy Company Obligation) (Amendment) Order 2019 came into force on 1st January 2020 and includes a requirement for ECO measures to be installed by, or under the responsibility of, a person who is registered with TrustMark for the measure and for the work to be lodged into the TrustMark Data Warehouse.

Green Homes Grant Voucher Scheme (GHGVS)


The GHGVS1 is a government grant scheme for property owners and landlords in England to help pay for energy-efficient measures in their homes. In July 2020, the Chancellor announced a £2 billion Green Homes Grant Voucher Scheme in England to help homeowners and landlords improve over 600,000 homes to be more energy-efficient across England.

This scheme was planned to run from the end of September 2020 through to March 2022, however applications to the Scheme closed on 31 March 2021.

BEIS has requested that BSI republish the PAS 2030:2019 standard to allow the PAS 2030:2017 standard to continue to be used until 31st October 2021.

All works completed under the PAS 2030:2017 standard within the Green Homes Grant Voucher Scheme and Green Homes Grant Local Delivery Scheme must be completed and lodged within TrustMark Data Warehouse no later than 31st October 2021.

The decision to extend the PAS2030:2017 standard beyond 30th June 2021 only applies to the Green Homes Grant Voucher Scheme and Local Authority Delivery Phase 1. All other schemes will not accept PAS 2030:2017 from 1st July 2021.

The home energy-saving improvements carried out under the government’s GHGVS must be completed by a TrustMark Registered Business and for low carbon technologies must also be registered with the Microgeneration Certification Scheme.

Green Homes Grant Local Authority Delivery (GHGLAD)


In July 2020, the Chancellor announced £2 billion of support through the Green Homes Grant to save households money; cut carbon; and create green jobs. The Green Homes Grant comprises up to £1.5 billion of support through energy efficiency vouchers and up to £500m of support allocated to Local Authority delivery partners, through the GHGLAD.

The Green Homes Grant is a key part of the government’s plan to ‘build back greener’ and support the transition to net-zero carbon emissions by 2050.

The energy efficiency measures carried out under GHGLAD must be completed by a TrustMark Registered Business.  This requirement is not mandated by BEIS but by the Local Authorities themselves. Where TrustMark Registered Businesses install low carbon technologies, they must also be registered with the Microgeneration Certification Scheme (MCS).

Sustainable Warmth


Sustainable Warmth is a competition being launched to bring together two fuel poverty schemes (LAD Phase 3 and HUG Phase 1) into a single funding opportunity for Local Authorities (LAs).

The two schemes that make-up the Sustainable Warmth competition have a shared goal to contribute to the aims set out in the Sustainable Warmth: Protecting Vulnerable Households in England Strategy.

Funding is available to upgrade homes both on and off-gas grid and is comprised of:

1. LAD Phase 3: A third phase of LAD with £200m available. LAD3 has a refined scope to support low-income households heated by mains gas.

2. HUG Phase 1: £150m for low-income households with homes off-gas grid

Social Housing Decarbonisation Fund (SHDF)


The SHDF Demonstrator project is an initial investment to learn lessons and catalyse innovation in retrofitting for the Social Housing Decarbonisation Fund, for which the manifesto committed £3.8 billion of new funding.

These projects will demonstrate innovative approaches to retrofitting social housing at scale, using a whole-house approach. The projects will retrofit over 2,300 homes to bring them up to Energy Performance Certificate (EPC) band C or higher.

Details of the 17 local authorities to be awarded funding are available on the following page. Projects are expected to complete by December 2021.

Warm Home Discount Scheme


In line with the overarching direction of government policy ambition that energy efficiency measures installed under government schemes will be carried out by TrustMark Registered Businesses. The 2021/2022 extension to the Warm Home Discount Scheme (WHD) includes a new requirement that boilers and central heating systems installed and repaired under the scheme are carried out by a TrustMark Registered Business and work must be lodged into the TrustMark Data Warehouse.

The WHD is a government scheme for England, Scotland and Wales that supports low-income households with heating their homes.

The following document sets out defined Framework Operating Requirements for installations and repairs delivered under the WHD 2021/2022 extension.


Building Partnerships


TrustMark is also working with Sero, who through the Optimised Retrofit Programme has been awarded more than £7m in funding from the Welsh Government. The Optimised Retrofit project will see circa 1,400 homes across Wales made more energy efficient.

You can find out more about what they are doing by visiting their website.

Generally, all work started on and after 1st July 2021 must be carried out with PAS 2030:2019 certification and in compliance with PAS 2030:2019 and PAS 2035:2019. Lodgement to the Data Warehouse must be made by a TrustMark registered Retrofit Coordinator.
