Survey Type Finder: Which Survey Do You Need?
Choosing the wrong survey is one of the most common — and most expensive — mistakes in a UK construction project. The right survey depends on the project type, the stage of design, the level of detail the architect or engineer needs, and the deliverable format the design team works in. This guide walks through the typical UK project types, the survey that fits each, and the 2026 cost bands as a planning reference.
The five main survey types
Before choosing, it helps to know what each survey actually does:
- Measured building survey — captures the existing building (floor plans, elevations, sections, roof plan) to RICS accuracy. Used when the design work is inside or attached to an existing building.
- Topographical (land) survey — captures the existing land (levels, boundaries, features, services) tied to the OS National Grid. Used when the design work involves the site itself.
- Scan to BIM / 3D laser scanning — captures the existing building or site as a 3D point cloud, optionally delivered as a Revit BIM model. Used when the design team works in BIM or needs the existing conditions in 3D.
- Monitoring survey — tracks movement of a structure or ground over time. Used when construction activity may affect adjacent structures, or when a Section 80 / party wall award requires it.
- Setting out — transfers design coordinates and levels from the drawing into the ground. Used at the construction stage, not the design stage.
Most projects need only one or two of these. A few need three or four.
Quick finder (by project type)
| Project | Survey needed | | --- | --- | | Loft conversion | Measured building | | Rear or side extension with garden | Combined (measured building + topographical) | | New build on a cleared site | Topographical + setting out | | New build on a site with an existing building to demolish | Combined (topographical + measured building) | | Basement excavation under an existing house | Combined + monitoring | | Interior fit-out or refurbishment | Measured building | | Drainage design | Topographical (with invert levels) | | BIM Level 2 design | Scan to BIM | | Heritage recording (Grade I or II listed) | Scan to BIM (high accuracy) | | Party wall award works | Measured building + monitoring | | Section 80 (Town & Country Planning Act) | Monitoring |
Quick finder (by question)
If you are not sure which project type applies, work through these questions:
- Do you need interior data of an existing building? → Measured building survey.
- Do you need exterior / land data of a site? → Topographical survey.
- Do you need both interior and exterior data? → Combined survey.
- Do you need a 3D BIM model of an existing building? → Scan to BIM / 3D laser scanning.
- Do you need to track movement over time? → Monitoring survey.
- Do you need to transfer a design onto the ground at construction stage? → Setting out.
What each survey delivers
| Survey | Typical deliverables | | --- | --- | | Measured building | 2D CAD (DWG + PDF) — floor plans, elevations, sections, roof plan | | Topographical | 2D CAD (DWG + PDF) tied to OS National Grid, with spot heights on ODN | | Combined | Both of the above, on a single coordinated drawing | | Scan to BIM | 3D point cloud (E57, LAS, PTS) and/or Revit BIM model at LOD 200–400 | | Monitoring | Tabulated readings over time, with trigger-threshold alerts | | Setting out | Coordinates and levels transferred to the ground, with an as-built record |
All icelabz surveys are delivered to the RICS Measured Surveys of Land, Buildings and Utilities, 3rd edition standard, with a signed accuracy statement.
2026 cost bands (ex VAT, UK planning reference)
| Survey | Cost band | | --- | --- | | Measured building (small house) | £595–£1,500 | | Measured building (large or complex) | £1,500–£3,500+ | | Topographical (small site, under 0.1 ha) | £595–£800 | | Topographical (medium, 0.1–0.5 ha) | £800–£1,200 | | Topographical (large or complex) | £1,200–£2,500+ | | Combined (measured + topographical) | £900–£2,000 | | Scan to BIM (LOD 200) | £1,200–£2,500 | | Scan to BIM (LOD 300) | £2,000–£5,000+ | | Monitoring | £295–£495 per visit | | Setting out | £400–£1,200 per stage |
These are 2026 UK planning-reference figures. The final figure depends on the site size, complexity, access, accuracy band, and deliverable format. icelabz provides fixed-fee quotes once the brief is confirmed.
What this finder is not
This finder covers the surveying work that icelabz delivers (measured building, topographical, scan to BIM, monitoring, setting out). It does not cover:
- RICS HomeBuyer Report (Level 2) — a condition report on a residential property you are buying. This is delivered by a RICS-regulated surveyor, not by icelabz.
- RICS Building Survey (Level 3) — a more detailed condition report. Again, delivered by a RICS-regulated surveyor, not by icelabz.
- Mortgage valuation — for the lender, not for you. Delivered by the lender's panel valuer.
- Structural engineering calculations — for the structural engineer, not the surveyor.
- Planning application drawings — for the architect or planning consultant, not the surveyor (although the survey often feeds into the planning drawing).
If you are unsure which professional you need, the icelabz team can point you in the right direction.
