Most building height surveys are commissioned for one of three reasons:
If your building sits within a metre or so of either threshold, a measured survey is the only reliable way to confirm classification. Counting storeys or estimating from drawings is not sufficient under the Act.

Brilliant service - we were in a desperate position needing to documentation relating to a landlord certificate and they came out the next day squeezing us into their schedulePosted on Minniedale Projects15 November 2022Trustindex verifies that the original source of the review is Google. 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 re-furbishment work. We had a tight time scale 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.Posted on Billy Buckley5 November 2022Trustindex verifies that the original source of the review is Google. I contacted Tom to carry out a Topographic survey, and cannot recommend them enough. Nothing was to much, and I was kept up to date with everything as it happened! Great company to deal with and reasonably priced.Posted on Erika Bright Home Estate1 September 2022Trustindex verifies that the original source of the review is Google. Very professional company and great service overall! I have used this company on a few occasions and every time the process is quick and efficient, I will be calling them again.Posted on Paul Bagnall17 August 2022Trustindex verifies that the original source of the review is Google. We use THS a lot to obtain survey information for the creation of AVR or Verified Views. We require set-up survey points in 3D CAD to help montage CGIs into photographs. We provide mark ups and location references of between 50 and 120 points and THS are really good at hitting site and recording them swiftly, accurately, and providing the data in a perfect form for us to carry out our imaging work. They also think on their feet and if there are interrupted site lines or other site features preventing measurment, we can rely them to look for alternatives and record them for us. In summary, THS are flexible and professional collaborators. Paul Bagnall. Emperor VisionPosted on Danielle Russ4 August 2022Trustindex verifies that the original source of the review is Google. Great service for our Topographical Survey. A friendly and reliable company.
If your building is anywhere near the 11-metre or 18-metre thresholds set out in the Building Safety Act 2022, you need a measured survey to confirm its classification. Estimating from drawings or counting storeys is not sufficient. The Act requires measurement from the lowest external ground level adjacent to the building to the finished floor of the highest occupied storey.
Our standard method uses a Leica Disto laser measurer to capture levels at the lowest external ground point and the finished floor level of the top occupied storey, working up an internal stairwell where access allows. The two measurements are then differenced to give the building height as defined under Section 117 of the Building Safety Act 2022. We have written a step-by-step measurement guide if you want to understand the methodology in detail.
The Building Safety Act 2022 is UK legislation introduced after Grenfell to define safety responsibilities for residential buildings above certain heights. It creates two key categories: Relevant Buildings (11 metres or more, or at least 5 storeys, with at least 2 dwellings) and Higher-Risk Buildings (18 metres or more, or 7 or more storeys, with at least 2 residential units). Different duties and remediation responsibilities apply to each. We measure your building so you know which category, if any, applies.
Most building height reports cost between £200 and £500 + VAT, depending on building complexity and location. Use the instant quote tool for an exact figure for your building, or get in touch and we’ll send a fixed quote within one working day. You can also use our instant quote tool.
Quotes are returned within one working day. Most site visits take an hour or two. Reports are typically issued within three working days of the site visit. From enquiry to report in hand, you should plan for around a week for most buildings.
Our standard method does require internal access to a stairwell, as this gives the most accurate measurement. Where internal access isn’t practical, we can undertake external-only surveys using laser and total station equipment, with the trade-off being slightly reduced accuracy on the storey-by-storey breakdown. We’ll recommend the most appropriate method when you book.
We work across the whole of the UK from offices in Essex and London, and have undertaken international projects across Europe and West Africa. There’s no minimum or maximum building size. We’ve measured everything from low-rise flats to industrial high-rises.
We’re a TSA-accredited surveying practice with over 2,000 completed projects since 2013. Building height surveys are a routine part of our work, supported by Leica laser equipment, fixed pricing from £200, a 100% money-back guarantee, £1 million PI and £5 million public liability cover, and reports tied directly to Section 117 of the Building Safety Act. See our 5-star reviews on Google and Trustpilot.
We inspect and report on building conditions from the air using drones—eliminating the need for costly scaffolding or cherry pickers, and offering a far safer alternative.
We carry out regular building movement surveys to monitor structural changes over time, providing clear, easy-to-read reports that highlight any trends.
