Since 2002, FENSA has provided quality assurance and peace of mind for homeowners seeking to upgrade their windows and doors. With certificated proof that your new installation is building regulation compliant, energy efficient and registered with your local authority, homeowners are provided a safe and cost-efficient solution to replacing old, worn-out windows and doors. But who are FENSA, and how can sourcing an installer like Brackenwood (who is FENSA approved) benefit your home?

FENSA – A Brief History

April of 2002 saw the birth of FENSA, or the Fenestration Self-Assessment Scheme – one of the UK’s government-approved initiatives monitoring building regulation compliance for replacement windows and doors. Founded by like-minded installation companies from the Glass and Glazing Association, FENSA’s mission is and always has been to improve window and door replacements across England and Wales, by professionalising installers under The Competent Person Scheme and protecting homeowners. 

Over the course of two decades, FENSA has expanded rapidly. Between 2002 and 2018 for example, FENSA approved installers were able to issue 13 million certificates to homes around the UK – meaning that around 50% of all homes in the UK were now covered by the FENSA promise, backed by installation insurance for security and peace of mind.

So, how does FENSA work?

FENSA is effectively an assessment tool to help homeowners decide upon a quality, approved installer whilst feeling safe in the knowledge that the installation adheres to building regulation standards.

The scheme issues certificates to properties that have recently had new window and door installations completed by a certified FENSA installer. In the past, your local authority would have had to come out to inspect and pass your installation, which was often expensive and time-consuming. With a FENSA approved installer, they can self-certify the work due to quality-controlled assessment by the scheme.

Through this assessment of these FENSA approved installers, the certification process allows homeowners to gain safe, secure window and door installations that are building regulation compliant, registered with the homeowner’s local authority and that prioritise energy efficiency within the home.

FENSA is the scheme that ensures that your chosen installer is approved. This means that they maintain building regulation requirements throughout the installation process and beyond, as well as providing you with a FENSA certificate as a guarantee of quality work. 

What is a FENSA certificate?

A FENSA certificate is a document that is issued to you – the homeowner – once your registered FENSA tradesperson has informed your local authority that your windows and doors have been replaced. In the past, homeowners have had to do this themselves, as it is a legal requirement to register all building upgrades with your local authority. 

Your certificate will be issued to you for safe keeping, but it will remain with your property if you choose to sell your home later.

You will have heard of a FENSA certificate if you have recently replaced old windows and doors with a registered installer like Brackenwood. Once your windows or doors have been installed, your certificate will be issued, and it will last the lifetime of the installation itself.

Whilst it is important to understand who FENSA are, it is also important to understand what the organisation represents. For homeowners like yourself, it provides assurance in a job done right. All installations are insured by the installer. It also provides relief from the costly experience of having to approach your local authority and getting a building inspector to certify your installation. Those days of having to add extra into the budget to cover this process are long gone! Not only that, but thanks to twenty years of government approved certification, the FENSA name is associated with true quality and trust. So, when you employ an installer like Brackenwood, who is certified by FENSA, you can trust that the job is done correctly, meeting local authority building regulations in an energy efficient manner.

What are the benefits of FENSA to me, the homeowner?

The idea of what FENSA represents sounds great, but what about the tangible benefits to you, the homeowner? With a FENSA approved installer, you get:

  • Building regulation compliant installation
  • Registration of your installation with your local authority
  • Verification that your installer’s guarantee is insured 
  • Energy efficiency
  • Peace of mind
  • Cost efficiency 
  • Timesaving – cutting down the length of time it takes to have your installation approved
  • A certificate documenting the authenticity of the work (and who doesn’t want a certificate – right?!)

So, what happens when you choose an installer without FENSA accreditation? 

You may find someone you trust or that is recommended by Bob from down the road. The installer arrives to complete the work. He seems genuine and gets on with the work without issue. He installs your windows and seems to have done an excellent job. He leaves. 

You’re happy with the work, but you have forgotten to call your local authority, pay the fee (which can be several hundred pounds itself) and get a building inspector out to check and register your new installation. What happens next? A year or two go by and you try to sell your home. As all the documents are examined as part of the sale, the buyer’s lawyer realises that there are no compliance certificates for your window and door installation. They raise this with your local authority, and you are fined for non-compliance. Not only that, but you realise that your home is not energy efficient and has been costing you extra money to heat this whole time. So, before you choose a window and door installation service, look for that FENSA logo and rest assured that the job is done right by professionally trained and assessed professionals protected by the FENSA promise, just like Brackenwood.
