Planning Considerations for Windows in Cascob
Most window replacements in Cascob 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 Cascob 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.
FENSA, CERTASS and GGF Membership Explained
FENSA (Fenestration Self-Assessment Scheme) and CERTASS are the two main competent person schemes for window and door replacement in England and Wales. Membership allows approved installers to self-certify that their work complies with Building Regulations, without the homeowner needing to apply to the local council. The Glass and Glazing Federation (GGF) is the trade association for the glazing industry, and GGF membership indicates a company that subscribes to its code of conduct.
All window specialists in our Cascob directory are checked for active registration with at least one of these bodies, so your installation will be compliant and certificated.

Repair vs Full Replacement — Understanding the Cost Decision
In some situations, repairing a window is a highly cost-effective alternative to replacement. Replacing a failed double-glazing unit within a sound frame costs a fraction of a full window replacement. Fitting new hardware — handles, hinges, multipoint locks — can restore security and ease of operation at modest cost.
However, if the frame itself is structurally compromised — warped uPVC, significant timber rot, damaged cill — repair may only defer the inevitable. A honest Window Specialists in Cascob will give you a straightforward assessment of whether repair represents genuine value or whether the money would be better spent on a replacement that will last another 20–25 years. Get the repair option costed in writing before committing to full replacement.
Frequently Asked Questions — FENSA and Certification in Cascob
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.
