How we started
Tom Ayre started THS Concepts in February 2013. Before that he was a marine civil engineer, and he set up the business to give local architects reliable survey information to base their designs on. Architects often lacked the time and the equipment to measure a site properly, and getting that information right at the start of a project saves a lot of trouble later.
The business began at a kitchen table and soon moved into a small office nearby. Several office moves and more than 2,000 surveys later, THS Concepts is a team of eight, still based in Leigh-on-Sea.
We work on projects of every size, from one-bedroom flats to nuclear power stations, and from Essex and London to Edinburgh, Jersey and Liberia. We cover the full life of a project, from the first topographical survey or measured building survey through to setting out the new building and monitoring the structures around it.

Why clients use us
You speak to the surveyor
The person who measured your site is the person who answers your questions about the drawing. No account managers in between.
Quick to start
As a small team we are not tied into long contracts with big contractors, so we can often get to site quickly.
Kept informed
Email updates and phone support at every stage, and drawings delivered on the date we quoted.
Environmentally aware
We are a corporate sponsor of the Essex Wildlife Trust and are working on ways to reduce waste in surveying, including compostable survey targets.
Where we work
Most of our work is in London and the South East. Central London is a 45-minute train ride from our office and the M25 is 25 minutes by road. We travel nationwide for framework clients and one-off projects, and have worked in Bristol, Nottingham, Southampton, Edinburgh, the Channel Islands, Spain and West Africa.

What our clients say
Read our reviews on Google★★★★★
I was impressed by THS Concepts topographical survey services' professionalism and accuracy. They were efficient and reasonably priced. I highly recommend them.
★★★★★
We recently approached THS Concepts to carry out a level survey of the screed to the ground floor of a large residential property we were Project Managing. The property was undergoing extensions and refurbishment work. We had a tight timescale to receive the information, and THS Concepts delivered quickly and efficiently to meet our deadline. This is the second time we have used them and would highly recommend.
★★★★★
Having worked with THS for several years now, each project is treated with high professionalism every time. We would highly recommend their team.
