Most window replacements in Kensington fall under Permitted Development and do not require planning permission, provided the new windows are of similar appearance to the originals. However, if your property is in a conservation area or is listed, there are additional restrictions — you may need to match existing materials, profiles and glazing patterns, and planning consent may be required before any work begins.
An experienced Window Specialists working in Kensington will be familiar with local authority requirements and can advise whether you need to seek consent before proceeding. Failure to comply can result in enforcement action and a requirement to reinstate original windows at your own cost.
Local Experience You Can Rely On in Kensington
Window specialists who have worked extensively in Kensington bring practical advantages that national chains cannot always match. They understand the typical construction types found in local properties, know the quirks of older building stock in London, have established relationships with local planning teams and can respond quickly to any post-installation issues.
Local Window Specialists also depend on their reputation within the community, which gives them a strong incentive to do the job well and stand behind their work. Our directory prioritises locally based, locally experienced businesses.

Urgency and Emergency Glazing — How Timing Affects Cost in Kensington
Planned window replacements allow you to obtain multiple quotes, compare specifications and schedule the work at a mutually convenient time, which typically results in the most competitive pricing. Emergency glazing — following a break-in, storm damage or accidental breakage — removes that flexibility. Out-of-hours call-outs, rapid turnaround and the need to hold boarding-up materials in stock all add to the cost of emergency work.
If you have a non-urgent window problem, it is always worth addressing it in a planned way rather than waiting until failure forces your hand. Booking a survey with a Window Specialists in Kensington at a convenient time will generally result in a better outcome and lower cost than an emergency replacement.
Frequently Asked Questions — FENSA and Certification in Kensington
FENSA is a government-authorised competent person scheme that allows registered window installers to self-certify that their work complies with Building Regulations. This means you receive a compliance certificate without needing to separately notify the local council.
The work must be inspected and certified by your local authority building control department, at additional cost and delay to you. Uncertified window replacement can cause problems when you sell or remortgage.
FENSA registered installers submit installation details to FENSA within 30 days of completion. Your certificate is then posted to you directly from FENSA, not the installer. Keep it with your property documents.
CERTASS is an alternative government-authorised competent person scheme for window and door installers. It performs the same self-certification function as FENSA. Both are equally valid for Building Regulations compliance purposes.
In England and Wales, replacing a window with one of a different specification (e.g. upgrading to double glazing) must comply with Building Regulations and should be certified. Like-for-like replacement in the same opening with equivalent thermal performance still requires notification or self-certification.
