Do you know your tradespeople logos?

If you have ever tried to make any decorative or structural changes to your home, and used a tradesperson rather than trying to do everything yourself, you know that finding the right people to do the job can sometimes be a bit tricky. It might be finding an available plumber, or an registered electrician  where do you find them? Or do you go for a recommendation? How do you know you can trust them?


Well, one thing that can make choosing that tradesperson a little easier is if they have logos displayed, which show accreditation with a particular trade association or competent person scheme. So do you know how to spot the logos, and what they mean?




Ok, well the name is pretty easy, FENSA! In this article, a company correctly identified the FENSA logo too. But what does it mean if you use a company with a FENSA logo?


Well, here are some of the advantages of looking for the FENSA logo when having replacement windows and doors fitted in your property:


It could save you some cash if you use a tradesman who is part of the governments competent persons schemes, like a FENSA Fitter. Being part of one of these schemes means theyre qualified to meet building regulations and can self-certify their own work, so you dont have to pay extra to get the council to sign off the work. This could save you up to #250 and is much faster and easier! time of arranging assessment by Building Control


FENSA deals with the technical aspects of window fitting and FENSA Fitters undergo training and are aware of the latest technical updates to the Building Regulations for window installation


FENSA is the brand trusted by all local authorities, industry and government. All FENSA registered companies are continually re-assessed by an independent inspection body to ensure consistency of Building Regulations adherence and service.


FENSA proactively protects consumers from the cowboys: By withholding the scheme from those unable to pass FENSAs independent assessments; and also by reporting to Local Authorities and Trading Standards companies who erroneously claim FENSA registration, to enable prosecution.


All work carried out by a FENSA installer must: Give a 5  10 year guarantee and offer insurance backed guarantee for added peace of mind to cover the installers own guarantee


FENSA Certificates: Will be sent by FENSA directly to you to demonstrate compliance, vital in the event you need to sell your house. If you have lost your FENSA certificate  it is quick and simple to re-order online from this website, or simply call the team. The FENSA team can offer support to your solicitor when tracing missing certificates during the sale of your property


Consistent installations across a wide area: 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


So what other logos might be useful to know in the window industry?

What to check before appointing an installer

Check that you use a FENSA Approved Installer but also check the following:

  • Ask family and friends who have used installers about their satisfaction and whether they got a FENSA certificate.
  • Check the installer's references by talking to their previous customers.
  • Get at least three quotes and check you are being quoted like for like.
  • Cheapest is not always best and good contractors are always in demand.
  • Get quotes, timeframes and the fact that you will get a FENSA certificate all in writing. A proper written contract with an agreed completion date will help prevent confusion later on
  • Check the warranty on the installer's work and ensure they have enough insurance to cover their warranty. Domestic glazing installers that are registered with a competent person scheme like FENSA are legally obliged to provide warranty insurance to cover your installation should the company cease to trade within the life of the warranty.
