Company accreditations

Our commitment to achieving the highest quality in our loft conversions means we fully endorse the efforts of the various professional bodies and institutions in maintaining standards across the building industry. We are endorsed by, or partnered with, the following organisations:

Federation of Master Builders

To become a member of the Federation of Master Builders we have had to demonstrate a minimum of 3 years’ trading history, on-going job inspections, credit checks and director checks. This assures our customers that they are dealing with a reputable, solvent company.


TrustMark is a nationwide Government backed scheme This badge means we are a government approved, reputable trader. Our technical skills have been independently checked through on-site inspections to ensure a high quality of workmanship and trading practices. TrustMark is the only scheme that requires qualified inspectors to do these visits, so that tradespeople’s technical competence is checked as well as business practices and customer satisfaction.

ISO 9001 & 14001 registered

The ISO accreditations are the benchmark for quality management and environmental care. It ensures that Jon Pritchard ltd meets the highest possible standards in customer care, quality work practices and business management. These accreditations are annually audited by an independent provider to ensure that these standards are not only maintained but also continually improved.


By law, any person working on electrical installations must be registered with NIC EIC. Jon Pritchard Ltd prefers not to sub-contract out electrical work. By keeping things in-house we ensure peace of mind for our customers.

Velux approved

We are VELUX® Certified Installers. That means we’re constantly assessed by independent industry experts to check that our business is stable and secure, and that the quality of our work meets VELUX standards.

Health and Safety

In partnership with our Health & Safety advisors at C2 Safety we have set Health & Safety processes and procedures that ensure our teams operate in a safe manner, and that your site is organised and secured for everyone’s safety. Our dedicated independent H&S consultant makes spot checks to ensure our compliance and advise us of any improvements required.
