Make the switch to low carbon heating with a CQS approved installer

The Contractor Quality Scheme (CQS) has been developed to ensure high-quality, low carbon energy installations in Jersey.

CQS incorporates industry developed standards to ensure that installations are of a high quality and demonstrate a clear commitment to customer care and protection.

Securing approval under the Scheme will demonstrate a contractor meets industry standards; highlighting quality, compliance and encouraging the growth of green skills locally.

Low carbon heating technologies covered by CQS will initially include air source heat pumps, electric flow boilers, electric storage heaters and panel heaters, with additional technologies to be added as the Scheme is further rolled out.

Working with the Government of Jersey

The Scheme provides support to the Carbon Neutral Roadmap of policies to enable Jersey to lower emissions in order to reach its goal of net zero by 2050. As per policy HT1, government are running a low-carbon heating incentive which provides funds to businesses and households wishing to switch out their fossil fuel powered heating systems to low carbon alternatives.

To access the incentive, contractors will need to be approved by the Contractor Quality Scheme.

“We are really well placed to support the Government of Jersey with
the rollout of a quality assurance Scheme to support the low carbon
heating rollout. This scheme will drive high-quality low-carbon heating
installations, provide consumer confidence and support increasing the
number of installers with green skills.”


CQS Approval

Contractors going through approval under the Contractor Quality Scheme will be assessed to demonstrate they meet the required quality standards and customer service.



Below, you can find a list of CQS approved contractors participating in the Scheme. Each of the contractors meet industry standards of quality and compliance.

These contractors can access the Government of Jersey’s low carbon heating incentive on behalf of homeowners and businesses.
