Is Design Fyi Ltd FENSA or Certass registered?
This directory does not confirm registration. Window and door installers self-certify their work against Building Regulations through a Competent Person Scheme — mainly FENSA or Certass — so check the company name or postcode (LS2 7JU) directly on the FENSA or Certass website before booking, and ask to see the certificate number.
How do I get a quote from a window installer in Leeds?
Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the LS postcode area, who contact you directly. Leeds has 290 registered window and glazing businesses in this directory, though the installers who quote are not necessarily among them. It is free and there is no obligation.
What is a FENSA or Certass certificate and why does it matter?
It's proof the window or door installation meets Building Regulations (thermal performance, safety glazing, ventilation) without a separate council building control sign-off. Without one, selling the property can mean paying for retrospective building control inspection or indemnity insurance, so keep the certificate with your house documents.
Does a listing here mean Design Fyi Ltd is recommended?
No. Companies appear in this directory because they are on the Companies House register under a window/joinery installation trade code. A listing is not vetting, endorsement, or a guarantee that the company is trading or FENSA/Certass registered.
How many window and glazing companies are there in West Yorkshire?
This directory holds 1,045 active window and glazing businesses across 53 towns in West Yorkshire, all from the Companies House register. Leeds accounts for 290, among the county's busiest. About 39% of West Yorkshire's registered window and glazing firms were incorporated in the last three years, so weigh incorporation date and FENSA/Certass registration, not just company age.
