Is Kbuildingbrothers 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 (SE26 6ED) 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 London?
Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the SE postcode area, who contact you directly. London has 1,582 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.
Do uPVC windows need any maintenance?
Not much, but not none. Wipe the frames a few times a year, lubricate hinges and locks annually, and keep the drainage channels along the bottom of the frame clear so water can't pool and find its way inside. There is no statutory annual service like a boiler needs.
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 Kbuildingbrothers 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.
