The doors & windows / double glazing industry have several Associations & Institutions that can provide further help and assistance on a range of matters. They promote best practice as well as provide standards that retailers & installers should adhere to.

FENSA

FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. Every FENSA Approved Installer, from large national brands to small local companies, is assessed regularly by us to ensure its standards are continually maintained.

FENSA’s mission is to improve window and door replacements across the UK, by professionalising installers and protecting homeowners. They make sure the work complies with building regulations, is energy efficient, and registered with the local council. And verify that every FENSA Approved Installer’s guarantee is insured.

Since 2002, FENSA has been authorised by the government to issue the renowned FENSA certificate: proof that your window and door installations are compliant, energy efficient, and registered. This proof is vital when selling your home. When you use a FENSA Approved Installer, rather than having to arrange an inspection from your Local Building Control Officer, the team at FENSA notify them for you – and you get a certificate to prove it.

Glass & Glazing Federation

The Glass and Glazing Federation (GGF) represents companies that manufacture, supply or install glass and glazing products in the UK and internationally. Being the industry authority, the GGF promotes best practice and helps shape the highest technical and health & safety standards. The Federation is also the industry’s main voice in local and national politics influencing policy and legislation.

As well as offering an array of benefits to its members, the GGF guides and protects homeowners when buying glass or glazing products and services.

Assure

Assure is an official, UKAS-accredited Competent Persons Scheme authorised by the Ministry of Housing, Communities and Local Government (MHCLG) for the replacement of windows, roof windows, roof lights and doors in England and Wales

Certass

Certass is Government authorised to operate a Competent Person Scheme and is a UKAS accredited Certification Body. UKAS (United Kingdom Accreditation Service) is a Government approved body which is internationally recognised to accredit Certification Bodies. It accredits a Certification Body against an internationally recognised standard. Certass is accredited to operate product certification schemes against the standard BS EN17065.

A Competent Person Scheme allows an installer to self-certify that their work complies with all the local Building Regulations. This means that they can complete the work on your home without needing to submit a building notice or having local authorities carry out an inspection, saving you lots of time and money.
