FENSA Registration and Compliance Costs for Windows in Thornaby-on-Tees
When a FENSA or CERTASS registered installer replaces windows in Thornaby-on-Tees, a registration fee is payable to the competent person scheme to cover the cost of issuing your compliance certificate. This fee is usually modest and is typically included within the installer's quote rather than charged separately — but it is worth confirming this when comparing proposals.
If a window company you are considering is not FENSA or CERTASS registered, you would need to apply to the local authority building control department yourself and pay their associated fees. This route also involves an inspection visit, adding both cost and delay to the project. Using a registered Window Specialists avoids all of this.
Frequently Asked Questions — FENSA and Certification in Thornaby-on-Tees
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.
