Is Cowalk Construction 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 (NN2 7QJ) directly on the FENSA or Certass website before booking, and ask to see the certificate number.
How much does window replacement cost in Northampton?
A single uPVC window in Northampton 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.
What does this page tell me about Cowalk Construction Ltd?
The registered company name, registered office address, Companies House number and incorporation date, all taken from the public Companies House register. It does not include reviews, prices, staff details, or confirmation that the company is currently trading.
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.
