If you’re curious about the condition or history of a piece of land or property, a site assessment can shed some light on the situation.
Perhaps you already own the building, and you’d like to carry out a rebuild cost assessment for insurance purposes. Or maybe you’re eyeing a new plot and want to be sure it’s suitable for development. Whatever the case, a professional site assessment can flag potential issues early, giving you peace of mind and possibly saving you a lot of money in the long run.
To help you get started, we’ve rounded up ten trusted site assessment providers in the UK. Whether your project is residential, commercial, or industrial, these experts can help you navigate the process with clarity and confidence.
What Does a Site Assessment Provider Do?
Great question. In short, they help you get the full picture of what’s going on beneath (and around) your property. Performed properly by a reputable provider, they’ll flag anything you need to know before committing to a purchase, development, or rebuild.
Depending on your initial goals, they might offer:
- Environmental checks: Is the land contaminated? At risk of flooding? Home to an armada of Great Crested Newts (a protected species in the UK)?
- Geotechnical surveys: What’s the soil like, and is it stable enough to build on?
- Rebuild cost assessments: How much would it cost to rebuild the property from scratch, if the worst happened?
- Planning support: Are there restrictions or risks that could put a stop to your plans?
- Historic land use reports: What’s happened on the site in the past — was it used for manufacturing, did it handle hazardous waste, etc?
- Legal and compliance checks: Does everything line up with current building and environmental regulations.
Essentially, they take a lot of unknowns off your plate, and help you move forward, safe in the knowledge that you’re not destroying a habitat or inadvertently unearthing nuclear waste…
List of Top 10 Site Assessment Providers for UK Property Owners
1. Rebuild Cost Assessment

Rebuild Cost Assessment is a specialist provider focused on one thing: making sure your property is properly insured. Using detailed surveys and cost modelling, they calculate the accurate rebuild value of a building — not its market value, but what it would cost to rebuild it from the ground up in the event of a total loss. This figure is crucial for property insurance, yet it’s often underestimated or guessed.
Rebuild Cost Assessment offers both a desktop-based and in-person site rebuild cost assessment, and their team includes RICS-accredited surveyors. Their service is fast, professional, and tailored — ideal for homeowners, landlords, and commercial property owners alike. With underinsurance affecting thousands of UK buildings, their reports offer an easy way to protect your assets without overpaying on premiums.
2. Groundsure

Groundsure is a leading name in environmental and property risk data, offering reports that help clarify what’s really going on beneath the surface of a site. While their assessments cover everything from contaminated land and flood risk to historical land use and planning constraints, many professionals also rely on tools like CRM software for real estate agents to manage client relationships and streamline property transactions.
What sets Groundsure apart is how accessible their reports are — clearly structured, easy to understand, and packed with useful visual data. They’re a popular choice with conveyancers, surveyors, and developers, and offer reports tailored for residential and commercial use. If you’re making a big decision about a property — buying, selling, or building — Groundsure helps you go in with your eyes open.
3. Delta-Simons (now Lucion)

Delta-Simons — recently rebranded as Lucion — brings heavyweight environmental expertise to the table, with decades of experience in land assessment, geotechnical surveys, and sustainability consulting. They’re best known for tackling complex sites — whether that’s land with an industrial history, areas under tight planning regulations, or developments requiring environmental remediation.
Their team includes specialists in environmental impact assessments, contaminated land strategy, and ESG reporting, so you get deep, technical insight paired with a strategic, solutions-focused approach. While their services are often used on large-scale commercial or mixed-use projects, they also support smaller developments that need help navigating regulatory or environmental challenges. Lucion combines scientific rigour with real-world practicality, making them a valuable partner for anyone developing or managing land in tricky or sensitive areas.
4. RPS Group

RPS Group is a global consultancy that offers a wide range of site assessment services, including environmental, planning, and engineering reports. They help clients across various sectors — from landowners and developers to local authorities — tackle complex site challenges.
RPS provides detailed environmental assessments, flood risk analysis, and planning consultancy, making them a strong choice if you’re trying to navigate tricky regulatory environments. They have a deep understanding of local and national planning policies, and their team is skilled at identifying potential risks before they become costly problems. With their experience on both residential and large-scale industrial projects, RPS can deliver tailored advice that ensures your site is ready for whatever comes next.
5. MLM Group (Part of Sweco)

Their team covers everything from structural design and drainage to transport planning and ground investigation. That means they can look at a site from multiple angles and flag any technical issues before you get too far down the line.
If you’re working on a more complex plot or juggling several consultants, having a team like MLM on board can help bring everything together. They’re especially useful on mixed-use or infrastructure-heavy sites, but they also work with residential developers looking to tick off all the early-stage boxes.
6. Terra Firma

Terra Firma offers specialist ground risk reports that zero in on geological hazards, mining history, and land stability — all factors that can significantly affect the safety, value, or insurability of a site.
Their reports are designed to integrate seamlessly into conveyancing and development workflows, with clear summaries and accessible recommendations, making them a top pick for anyone seeking no-nonsense insights into what’s happening underground.
Terra Firma’s data is especially valuable in areas with a history of mining or subsidence, where unseen risks can quickly turn into costly problems. Whether you’re assessing a site for purchase or preparing for construction, their reports help you avoid surprises and make more confident decisions about what to do next.
7. EB7

EB7 is a consultancy that combines building and planning expertise to give you a well-rounded view of your site’s potential.
Their reports are especially useful if you’re working on a project in a densely built-up area, where planning and design constraints can be tricky. They cover things like rights of light, feasibility studies, and measured surveys, helping you understand both the physical and legal limits of what you can do with a site.
EB7’s team uses advanced 3D modelling tools to visually demonstrate how your development might interact with its surroundings. This means you can get a clearer sense of how a project will fit into the local environment — and where the risks lie. Their services are ideal for anyone needing clear, visual, and legally sound advice when tackling complex urban or planning-sensitive developments.
