About CET

Our Story

Established in 1988, CET began as a materials testing house and quality assurance service for the Construction industry. Since then, we’ve grown exponentially through organic expansion and acquisition. Through the natural connection between materials testing and subsidence investigation, we then grew our Property Assurance division, serving as an outsourcing partner for some of the biggest and best known insurers in the UK.

In the last two years, we’ve more than doubled in size and seen two distinct divisions flourish into successful businesses. In 2020, to better serve the needs of our customers, we completed the process of formally separating these into CET Property Assurance and CTS (Construction Testing Solutions).

Today, CET Property Assurance looks after the Home Emergency policies for one in four UK properties, ithe UK’s leading provider of subsidence investigation, delivers nationwide drainage investigation & repair services and provides a range of specialist property services to the Insurance Sector.

CET does the right thing for customers, always – and that means creating bespoke services, keeping them informed, treating them fairly and always delivering on promises. Whatever the challenge, we roll up our sleeves, get stuck in and sort it out quickly. We work hard and won’t stop until we’ve finished the job to the customer’s satisfaction.

Because CET’s services areinter-connected, they’re quickly able to become interdependent. This is especially valuable at peak times, when projects and workloads increase significantly due to seasonal or other extraordinary factors.
