Hi, I’m Tom, founder and co-director of THS Concepts. I started the business in February 2013. Before THS Concepts, I was a marine civil engineer working for a company called Red7Marine.

I started the business to provide local architects with quality survey information to base their proposed designs from. Obtaining accurate survey information for a building project from the start is important. I found that architects often lacked the time and the equipment to undertake this task correctly.

The business was started from my kitchen table, however, this quickly graduated to a small office nearby as the business grew.

7 years, three office upgrades and about 1,500 jobs later, THS Concepts is a team of seven people and one of the leading surveying businesses in South East England. We’re based in Leigh-on-Sea, recently voted the happiest place to live in the UK.

About Us

We take time to ensure our clients get the exact information they need for their projects. We cover a range of different surveying and drawing types including monitoring surveys, measured surveys, setting out more. We work with clients from the start to an end of a design project, from the initial survey through to setting out.

Time and time again, we hear horror stories of companies that produce poor quality drawings, inaccurate surveys and simply don’t answer the phone. THS Concepts promises to keep you informed at every step of the project with email updates and phone support. Our 5 star Google / Trustpilot reviews back up our thorough standards.

Since 2013, we have been helping on a range of different project sizes and locations. We have worked on nuclear power sites to 1 bedroom apartments, from Liberia in Africa to Edinburgh Scotland. If you have any questions then please don’t hesitate to get in touch.

Client Focused
No two projects are the same which is why we always approach each project with full flexibility and try to understand exactly what the client requires.

Project Speed
As a small team of Surveyors and Draughtsman, we can often visit your property or make a start on your project quickly as we aren’t tied into long contracts with big contractors.

Client Relationships
We aim to make your life as easy as possible. Our 4.9 star Google & “great” Trustpilot reviews demonstrate the level of customer service we provide both before and after a project has finished.

Environmentally Conscious.
We are a corporate sponsor of the Essex Wildlife Trust and have on going projects to reduce waste in Surveying. These include a project to manufacture compostable surveying targets to help reduce waste and plastic.

From our office in Essex, we undertake on-site projects across the United Kingdom and internationally.

We typically provide our on-site surveying services to clients across London and the South East. With a quick 45-minute train journey into central London or a 25-minute drive to the M25, we are ideally placed to serve clients in locations such as Essex, Kent, London, Hertfordshire, Surrey etc.

We do regularly operate outside of the South East and have undertaken work nationally in places such as Bristol, Nottingham, Southampton, the Channel Islands and Edinburgh. Internationally we worked in Liberia in West Africa and Ibiza, Spain
