TrustMark is the Government Endorsed Quality Scheme that covers work a consumer chooses to have carried out in or around their home.

C The Lite is accredited by TrustMark, and can take part in the Green Homes Grant scheme which covers green home improvements ranging from insulation of walls, floors and roofs, to the installation of low-carbon heating, like heat pumps or solar thermal – measures that could help families save up to £600 a year on their energy bills.

When you choose a TrustMark Registered Business, you are dealing with an organisation that has been thoroughly vetted to meet required standards, and has made a commitment to good customer service.

Green Deal Approved

Green Deal is the name of a Government initiative to encourage homeowners, tenants and landlords to make energy improvements to their properties.

To become a Green Deal approved installer, our business underwent a rigorous authorisation process to ensure that our customers receive the highest standards possible on their install.

Gas Safe

Gas Safe Register is the only official gas registration body of gas businesses and engineers in the United Kingdom, Isle of Man and Guernsey. By law, all gas businesses must be on the Gas Safe Register – C The Lite has been on it for 6 years.

A gas engineer can only be aligned to a registered business and be issued with a license to undertake gas work on behalf of a registered business if they hold a valid and current qualification, which ours do. This evidence of competence relates only to matters of gas safety and is obtained by every engineer through a recognised route of training and assessment.

Qualitymark Protection Accreditation

C The Lite is Qualitymark accredited by an organisation that has been actively safeguarding consumer investments in home improvements since 1996. In this time, they’ve helped the home improvement industry raise installation standards, strengthened the vetting and accreditation procedures, while providing consumers with quality financial protection for their home improvements.

They specialise in the supply of deposit and stage payment protection insurance and insurance backed guarantees for the home improvement industry.


OFTEC is the Oil Firing Technical Association. It is a ‘competent persons scheme’ that recognises companies approved to install oil, solid fuel and renewable heating equipment and to main oil and solid fuel systems.

In order to become OFTEC registered, C The Lite completed an approved training course and passed an assessment. We are reassessed regularly by OFTEC to ensure we continue to meet the required working standards to remain OFTEC registered.

Choosing an OFTEC registered installer means that you will receive an official certificate to confirm that the work done for us meets the official industry standards for safety and quality.
