Before you appoint an installer to replace your windows and doors, ask them: “Will I get a FENSA certificate when the job’s done?” Why? Because their answer to that one, simple question will tell you immediately whether they are right for you.
If they say no, you should say no.
Why? Because a FENSA certificate provides proof that your installer’s work complies with Building Regulations, uses energy efficient products, and is registered with the Local Council (a legal requirement).
Also, it means their warranty is insured (this is the case for all FENSA certificates issued after June 2014). Good to know, in case anything goes wrong and the company is not around to honour their warranty. There are many unprofessional installers out there, so you need to be careful.
Remember, only a FENSA Approved Installer can get you a FENSA certificate. It’s all the proof you need of a job done right.
