Why and how does Worcester Bosch Group offer accreditation to some installers?

Worcester want to provide homeowners with peace of mind when they are upgrading their home heating system and only invite heating engineers who are deemed as reputable, quality conscious and representing value for money.

Worcester Accredited Installers must have relevant Gas Safe, OFTEC and/or MCS approval. WAI’s must also have attended Logic certified training courses on boilers, solar thermal systems, heat pumps and/or underfloor heating.

Worcester check the installers’ Gas Safe, OFTEC and/or MCS accreditation on a regular basis. However WBG Heating always recommend to homeowners that they verify a heating companies membership status with the awarding bodies directly via their relevant websites.

Extended Guarantees

The standard Worcester product guarantee period is usually 2 years. Many of the accredited installers can offer longer guarantee periods ranging from 3 to 12 years depending on the type of boiler and parts used.

Worcester also run national guarantee promotions, so please check the Worcester website or ask us installer for up-to-date offers and product information.

Why do I need a heating and hot water installer?

Due to the complexity of modern heating systems, installation, service or repair work should only be undertaken by a qualified heating engineer.

This is why most manufacturers of heating and hot water appliances such as boilers, solar thermal and heat pumps only supply through trade merchants, rather than directly to end users.

What is Gas Safe Register?

Gas Safe Register is the only official Gas Registration body of Gas Business and engineers in the United Kingdom, Isle of Man and Guernsey. By law all gas businesses must be on the gas register.

A Gas Engineer can only be aligned to a registered business and be issued with a license to underate gas work on behalf of a registered business if they hold a valid and current qualification. The evidence of competence relates only to matters of Gas Safety and is obtained by every engineer through a recognised route of training and assessment.

Registration is only given based on the business having at least one Gas Safety qualified engineer.
The register is not a membership or trade association.
The register (and all services associated with it) is operated on behalf of the relevant Health & Safety Authority for each region in which it operates – i.e Great Britain, Northern Ireland, Isle of Man and Guernsey.
Gas Safe Register replaced Corgi as the only Gas Registration body in Great Britain and Isle of Man on April 2009 and in Northern Ireland and Guernsey on April 2009.

Can you get involved in financial issues?

Gas Safe Register remit is limited to Gas Safety and we are unable to investigate any contractual, financial or conduct issues that you may have. However, your local trading standards office, Citizens Advice Bureau or the environmental health department at your local council may be able to provide you with some guidance.

Federation of Master Builders

The Federation of Master Builders (FMB) is the UK’s largest trade association for the construction industry. We have a proud history of supporting and promoting small and medium-sized building companies – including sole traders – across England, Northern Ireland, Scotland, and Wales, since we were established in 1941.

We are champions of quality construction work and we advocate for continuous improvement in building standards. Before they can join the FMB, our members must go through a strict vetting process and independent inspection of their work, to ensure they meet the high standards expected of a Master Builder company. Not all builders pass the test.

We provide a wide range of business support services to help Master Builders to promote, protect and grow their business. We connect clients with professional, local builders they can trust. We build better as an industry through collaboration with government and industry partners.

We are a not-for-profit organisation run by members for members, which means membership fees are re-invested into supporting and promoting Master Builders.

We are certified by the Chartered Trading Standards Institute (CTSI) to provide Alternative Dispute Resolution (ADR) to FMB members and their clients, to assist in reaching a satisfactory outcome to building disputes.

Our ADR scheme is a free of charge, flexible process, conducted confidentially, in which we will actively assist both parties to work towards a satisfactory agreement. FMB members are required to participate in the process as part of the FMB’s Code of Conduct.

We employ four ADR officials, including one Director, one Manager and two case handlers. All were appointed on a permanent basis after a suitable interview and probationary period and receive regular specialist training relevant to their roles. They are trained to operate the FMB Dispute Resolution procedure in an impartial and fair manner. We maintain a Conflict-of-Interest log to ensure that this is the case.

The dispute process is explained in the How does this work section below. You can also download the latest FMB Dispute Resolution annual report detailing our dispute services from 1 October 2021 to September 2022 for more information.
