XP Surveys provides professional topographical surveys and detailed site plans for planning, design and construction projects across London, the Home Counties and the wider UK. Our experienced topographical surveyors work across residential, commercial and infrastructure projects.
Also referred to as a topographic or topo survey, a topographical survey records the land levels, contours, boundaries and site features your project needs for planning applications, drainage design and construction coordination. New to topo surveys? Read our full guide:
what is a topographical survey?

Our topographical surveys deliver far more than a basic site plan. From site contours and drainage paths to retaining walls, utility covers, access routes and hard landscaping, every dataset is captured with advanced laser scanning and robotic total stations, then processed into CAD-ready drawings and scaled digital terrain models that integrate directly into AutoCAD, Revit and ArchiCAD workflows.
Our nationwide survey teams regularly support infrastructure, residential and commercial developments across London and the wider UK, giving architects, engineers and developers a dependable foundation of terrain data from the earliest stages of a project.
Watch how our survey teams capture high-precision terrain data using advanced laser scanning and robotic total stations to deliver CAD-ready topographic survey outputs for architects and engineers.
Our surveys are widely used by:
Every survey is tailored to your site conditions and project brief. Using the Trimble X7 3D Laser Scanner and Leica TS16 robotic total station, we capture precise land contours, terrain levels, boundaries, vegetation, drainage infrastructure and hidden surface features — processed into engineer-ready outputs:

Architects, developers and engineering teams rely on XP Surveys for planning-ready topographical survey data that identifies site constraints, level changes and coordination challenges before projects progress into detailed planning and construction, minimising redesign and reducing risk during design development.
Beyond design teams, landowners and purchasers use our surveys to obtain reliable area calculations and site intelligence that support valuation, acquisition due diligence and long-term development planning.
Topographical surveys play a critical role in planning, design and construction by providing accurate terrain and site data at the earliest project stages. By capturing detailed land levels, surface features and site constraints, these surveys enable architects, developers and engineers to make informed decisions with confidence and reduce risk throughout the project lifecycle.
Common applications include:
We use the latest technology to accurately capture land data and features; this includes the Trimble X7 3D Laser Scanner and the Leica TS16. Read more in our insight into the topo survey equipment we use.
The cost of inaccurate terrain data rarely shows up until it’s expensive. Incorrect levels lead to drainage designed for falls that don’t exist on site. Missed features surface as clashes during construction coordination.
Earthworks calculated from unreliable contours mean mispriced groundworks and planning submissions built on flawed site data invite delays, objections and redesign costs that far exceed the price of the survey itself. Getting the terrain data right at the outset is the cheapest risk reduction a project can buy.
Every topographical survey is captured to millimetre-level accuracy typically within 2mm using robotic total stations and 3D laser scanning tied to GNSS survey control. Site data is checked against control observations before processing, and every drawing passes internal quality assurance before delivery. Our surveys are produced in line with recognised industry survey specifications.
Just let us know what program you or your architect works in, and we will supply you with your survey drawings in the desired format — including 2D AutoCAD (.dwg), DXF, PDF, Revit (.rvt) and ArchiCAD.
Our land surveyor visits the site and sets up specialised measuring equipment accurate to within 2mm, recording the heights and distances between land features. This gives the surveying team the coordinates required to create a detailed map of the land, output in AutoCAD (.dwg), Revit (.rvt) or PDF format. Sample drawing below:
A topographical survey typically costs from £250 for a small residential site to £2,500+ for larger development sites, depending on site size, the level of detail required and access conditions. Most residential topo surveys fall between £350 and £1250, with CAD-ready drawings delivered within 3 working days of the site visit.
Topo survey pricing depends on:
Rather than generic estimates, we provide clear, fixed quotes tailored to your site. Use our instant quote tool to receive a fast, competitive price in minutes — for larger or more complex sites, our team will provide a detailed proposal outlining costs, timescales and deliverables.
To minimise costs, define your scope clearly upfront knowing exactly which features and levels you need to record, which avoids unnecessary survey time. You can also use Google Earth
to indicate the extent of land and features required before requesting a quote.
A topographical survey relates to land — levels, contours and site features. A measured building survey relates to a building’s floor plans, elevations and internal dimensions. For a full comparison, see our guide to topographical vs measured surveys .
Measured Building Example:
Topographical Land Example:
We carry out topographical surveys across every scale of project, including:
A live healthcare estate where survey work has to fit around clinical operations. Alongside internal survey works, our team carried out a topographical survey of the site’s external ground levels, access routes and drainage cover levels around the works area to give the project team reliable external level data for coordinating the works.

A constrained urban site in Islington with no existing records of the premises. Our topographical survey captured the site around the four-storey office and warehouse buildings’ boundaries, external levels and surrounding features, so the client could begin design discussions with their architect from a complete picture of both land and buildings.

It helps professionals understand a site’s existing conditions. A topographical survey is used to assess feasibility, support planning applications, and inform site design decisions by identifying levels, boundaries, drainage paths and any constraints on the land.
A professionally conducted topo survey can achieve accuracy within millimetres. At XP Surveys, we use advanced instruments including 3D laser scanners and total stations to ensure high precision across every project.
We provide topographical surveys throughout Greater London and the Home Counties, including Surrey, Essex, Kent and Hertfordshire. Searching for a topographical survey near you? Our teams cover projects nationwide — contact us to discuss your location and requirements.
Topographical survey costs start from around £450 for small residential sites, rising to £2,500+ for larger development sites. [VERIFY] The price depends on site size, access conditions and the level of detail required. Use our instant quote tool for a fixed price in under a minute, or contact us directly for larger or more complex sites.
The two biggest factors are site size and detail level. A survey recording boundary outlines and basic ground levels takes far less field and processing time than a full-detail topo capturing every kerbline, tree, service cover and level across a development site. Access restrictions and expedited turnaround also affect the price.
A topographical survey provides detailed elevation and surface feature data — levels, contours, drainage and site constraints. A land registry plan simply outlines legal property boundaries, typically with far less accuracy and no terrain information.
Yes. We can generate 3D topographic models suitable for design workflows or visualisations in Revit or ArchiCAD, depending on your project requirements.
Most residential and small commercial sites are completed in a single day. Larger or more complex sites may require two or more days on-site. CAD-ready outputs are typically delivered within 3 working days of the site visit.
Inaccurate terrain data is one of the most expensive mistakes a project can absorb — drainage designed to wrong levels or planning drawings based on incorrect boundaries cost far more to fix than the survey itself. Every XP Surveys topo is captured with survey-grade instruments and delivered as CAD-ready drawings your design team can rely on.
A topographical survey covers land — levels, contours, boundaries and site features. A measured building survey covers buildings floor plans, elevations and internal dimensions. Many projects require both, and XP Surveys provides both services in-house.
