FENSA stands for the Fenestration Self-Assessment Scheme. Following Government encouragement,
FENSA has been set up by the Glass and Glazing Federation (GGF) and other industry
bodies in response to Building Regulations for double glazing companies in England
When replacing windows, doors and roof lights in dwellings in England and Wales,
homeowners must comply with current thermal performance and Building Regulation
standards and ensure they get a certificate from a Competent Person scheme such
as FENSA or Local Authority Building Control. FENSA enables companies that install
replacement windows and doors to self-certify compliance under these Building Regulations
without the need for a separate assessment from Building Control.
FENSA obtains funds to supports its certification operations through a combination
of membership fees and inspection fees. FENSA does not aim to accumulate or distribute
any surpluses, but set its charges at levels appropriate to finance the continuing
operation and expansion of its certification product, and to provide prudent reserves
An independent report commissioned by the Government found FENSA to be
the most successful of all competent person schemes to date in the UK, across all
industries. FENSA is the leading brand trusted by consumers, all Local Authorities,
industry and Government.
FENSA is the industry standard for replacement window and door installers self-certifying
compliance with the building regulations.
Here is why you should look for the FENSA logo when having replacement windows and
doors fitted in your property:
Save time and costs:
- You do not have to register your window or door installation with the local authority
yourself. Not only is the FENSA approach much faster and easier – it is likely to
save you hundreds of pounds
- Compliance with the Building Regulations without the added cost and time of arranging
assessment by Building Control
- If you own properties across different local authorities – for consistency of quality
and price, you are able to use the same FENSA installer for all installations, as
they can work in all Local Authority jurisdictions
Confidence in FENSA installers:
- FENSA is the brand trusted by all local authorities, industry and government.
- An independent report commissioned by the Government found FENSA to be the most
successful of all competent person schemes to date in the UK, across all industries.
- Vetting: All FENSA registered companies are continually re-assessed by an independent
inspection body to ensure consistency of Building Regulations adherence and service.
- Nearly 9000 companies nationwide have joined FENSA which include glazing companies,
builders, national and smaller home improvements companies, local authorities, housing
associations, property developers. If all these companies trust and use FENSA, consumers
can too. If all these companies trust FENSA, homeowners can too.
- FENSA does not demand any specific brand of insurance from its installers – homeowners
and installers have freedom of choice over insurance providers whose policies are
underwritten by ‘different’ insurance companies (FENSA is not insurance-led)
- FENSA proactively protects consumers from the cowboys – not only by withholding
the scheme from those unable to pass FENSA’s independent assessments; but also by
reporting to Local Authorities and Trading Standards companies who erroneously claim
FENSA registration, to enable prosecution.
- Customers are able to provide a rating score for installers on the feedback form.
All notifiable work carried out by a FENSA
installer must offer:
For all replacement window and door installations that are notifiable to FENSA (click
here to find out which types of installations
fall under FENSA's remit), FENSA Registered Businesses are required to have in place
for their customers the categories of insurance stated below. It is a government
requirement that companies must have certain insurance policies in place where applicable.
Deposit Protection: If FENSA Registered Businesses take deposits in advance
of installations, they must give some form of deposit indemnity. Deposits may be
guaranteed by, for example, trade association Deposit Indemnity schemes, or credit
Guarantee or Warranty: FENSA Registered Businesses must give a guarantee
or warranty covering the cost of completing rectification work in respect of defects
for a period of ten years.
Insurance-Backed Guarantee (IBG): FENSA Registered Businesses must also back
up their Guarantee/Warranty with an independent insurance policy, in the event of
ceasing to trade. This is called an Insurance-Backed Guarantee (IBG).
Deposit Protection and IBGs (Insurance Backed Guarantee) can be provided by a range
of insurance providers. FENSA provides an 'approved' list of already vetted insurers
that FENSA Registered Businesses must use.
