Really happy with how it went, they were easy to get hold of, turned up when they said they would, and the survey drawings were spot on for our architect to work from. Would happily use them again.Posted on Google Adam MTrustindex verifies that the original source of the review is Google. We used THS Concepts for a topographical survey of a plot of land we're looking to develop with new houses. From the first contact they were easy to deal with and got the survey scheduled in quickly. The team were professional on site and the whole process was straightforward with minimal disruption. The final drawings were detailed and accurate, giving our architects and planning team exactly what they needed to move the project forward with confidence. Would definitely recommend THS Concepts and will be using them again as the development progresses.Posted on Google MarkW1989Trustindex verifies that the original source of the review is Google. Excellent laser scan and floor plan drawings from THS Concepts. Quick, accurate, and easy to work with. Highly recommend.Posted on Google Sarah BoveyTrustindex verifies that the original source of the review is Google. THS Concepts carried out movement monitoring for us during a large renovation in Leigh on Sea, needed as part of our party wall awards. Reliable readings throughout, kept us updated regularly and gave us real peace of mind during the works. Would recommend!Posted on Google michelle michelleTrustindex verifies that the original source of the review is Google. The point is, when you know diddly about a subject and are at the mercy of "professionals", it's really refreshing to come across a team that you genuinely feel you can trust. A highly professional and customer-focused service throughout. I would not hesitate to recommend them and would happily use them again in the future if the need ever arose. Chris took the time to explain everything in clear, layman's terms, making what could have been a complex process very easy to understand. He was attentive, professional, and took the time to understand exactly what was required for our project. Communication throughout was excellent, with regular updates and prompt responses to the questions I had. Lesley did a great job coordinating the appointment, Sam was excellent on site carrying out the scan, (even if he did have dodgy tattoos in the past), and Chris kept everything running smoothly from start to finish. The entire team delivered within the timescale originally quoted, which was greatly appreciated. What particularly stood out was Chris's willingness to go above and beyond, even offering to liaise directly with the third-party company receiving the drawings to ensure everything was suitable and met the required specifications. A shout-out also to ML for producing the drawings. Excellent service from start to finish.Posted on Google Tony CorradiTrustindex verifies that the original source of the review is Google. They were BRILLIANT!!! I’d definitely use them again. Polite, punctual and above and beyond in service too. Honestly they were all great but that’s what you get from a family run place. Carry on the good work guys and thank you. 🙏Posted on Google Kay QuinlanTrustindex verifies that the original source of the review is Google.

Lesley the Office Manager went out of her way to support us for a building height survey and to confirm no cladding. The surveyor was on time, helpful and quick with their report.

Costs vary significantly depending on the type of survey, site size, level of detail and access. A small residential topographical survey will sit at the lower end; a complex 3D laser scan of a heritage building or a long-term monitoring programme will be considerably more.
