Clark Building & Installation Services Limited

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 (NG8 6PX) directly on the FENSA or Certass website before booking, and ask to see the certificate number.

A single uPVC window in Nottingham typically runs £300 to £600 supplied and fitted; a full house of 8 to 10 windows is often £3,000 to £8,000 depending on style (casement, bay, sash-look) and glazing spec. Get two or three written, itemised quotes before agreeing to work.

Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the installer for recent local references, and confirm FENSA or Certass registration before any work starts.

This directory holds 391 active window and glazing businesses across 32 towns in Nottinghamshire, all from the Companies House register. Nottingham accounts for 236, among the county's busiest. About 38% of Nottinghamshire'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.
