Wessex Site Inspection


Steve Pollock, Director

The benefits of engaging a Clerk Of Works/Site Inspector are well documented. But the ability to engage a multi-disciplinary team of expertise such as exists in WSI Ltd, is quite unique.

Wessex Site Inspection was initially formed from within the National Health Service in 1992. The team of building and services engineering staff were responsible for the inspection and monitoring of hospital projects within the South and South-West of England.
In 1997, WSI broke away from the NHS and became a Limited Company. This breakaway allowed the team to provide services to not only the NHS, but also to other Clients including Schools, Colleges, Universities, Police Fire & Rescue, and Private Developers. Since becoming a privately run practice WSI has been involved with over 750 projects across the UK.






“Quality is Our Business” has long been our founding principle. Our aim is to provide impartial and independent assessments of works on-site, with a collaborative approach when needed but always with integrity at the fore of what we do everyday.

WSI currently employs a 30-strong team of highly experienced and qualified personnel who have spent much of their working life in the construction industry. We also have access to 120 more Clerk of Works and NEC Supervisors across the UK so that we are able to resource for any project location.

Our client roster boasts the likes of Aecom, Gleeds, Stace, Faithful and Gould and Mace to name a few. Also, we undertake many projects with the Department for Education, NHS, MOD and various councils and public agencies.

Due to our advanced white-labelling system, we are able to be engaged directly by clients or consultants alike. Although we are usually engaged on projects from £10m-£100m in value, we often become involved in smaller developments 

If you want your construction project to meet the highest standards of quality, adhere to contractual obligations, and stay within budget and schedule, then engaging our services is highly recommended. Our team can discuss your project specifics to determine the level of support required.

WSI have brought the role of Clerk of Works and NEC Supervisor to the forefront of innovation. Our proprietary QualiTech system saves 40% of admin time by automating processes so that inspectors can spend more time on-site and liaising. This, paired with over 3 decades of experience in the field, makes for a strong ally on all projects.
