As Built Survey Price: UK and London Guide

As Built Survey Price: UK and London Guide

Understanding what you should expect to pay for an as built survey — and why prices vary so significantly between providers — is one of the most effective ways to avoid overpaying or commissioning the wrong level of survey for your project. This guide covers as built survey pricing across the UK and London in 2025, with a breakdown by property type, survey method, and output format.

What Drives As Built Survey Price

Before looking at specific prices, it is worth understanding the factors that determine the cost of a measured building survey. This helps you evaluate whether a quote is reasonable and where you can save cost without compromising quality.

Property size The floor area of the building is the primary cost driver. Survey time on site scales approximately with the logarithm of the floor area — a 300m² property does not take three times as long as a 100m² property, but it does take meaningfully more time.

Survey method Total station survey is faster and more cost-effective for standard residential and commercial properties. Laser scanning costs more but is the appropriate method for complex geometries, heritage properties, and projects requiring BIM. Using laser scanning where total station would suffice is an unnecessary cost.

Output format 2D CAD drawings are the baseline — the lowest cost option. BIM models cost more because of the additional processing time required. Point cloud data adds further cost. You should only pay for the output format your project actually needs.

Location London postcodes typically carry a 20–40% premium over equivalent properties in the Midlands or North of England. This reflects survey team travel time, parking costs, and higher overheads — not quality differences.

Accessibility and complexity Properties that are cluttered, multi-level, or have restricted access take longer to survey. Heritage buildings with intricate detail require more survey time and more careful data processing. If a property has been significantly altered, additional time is required to resolve geometry.

Urgency Standard turnaround is typically 5–10 working days from the survey date. Expedited delivery — 48–72 hours for urgent planning or building control deadlines — carries a premium.

As Built Survey Price by Property Type

Residential — As Built Survey Cost

| Property type | GIA range | CAD drawings | CAD + BIM | |---|---|---|---| | 2-bed flat | 60–80m² | £400–£650 | £750–£1,100 | | 3-bed house | 100–130m² | £550–£900 | £950–£1,600 | | 4-bed house | 150–200m² | £800–£1,300 | £1,400–£2,200 | | Large detached house | 200–350m² | £1,000–£1,800 | £1,800–£3,200 | | Multi-unit residential | 500m²+ | £1,500–£5,000+ | £3,000–£8,000+ |

These prices are for standard 2D CAD drawings. Adding elevations and sections increases cost. BIM models are priced per square foot of GIA (see below).

Commercial — As Built Survey Cost

| Commercial type | GIA range | CAD drawings | CAD + BIM | |---|---|---|---| | Office floor (shell) | 200–500m² | £900–£1,800 | £2,000–£4,500 | | Office floor (fitted) | 500–2,000m² | £1,800–£4,500 | £4,000–£9,000 | | Warehouse/industrial | 1,000–5,000m² | £2,500–£9,000 | £6,000–£20,000+ | | Retail unit (high street) | 100–500m² | £700–£2,000 | £1,500–£5,000 | | Mixed-use development | 2,000–10,000m² | £5,000–£18,000 | £12,000–£40,000+ |

Commercial survey prices include NIA and GIA floor area measurement to RICS Code of Measurement Practice — a standard requirement for commercial letting and sale documentation.

BIM Survey Price

BIM survey pricing is typically quoted per square foot of GIA:

| BIM deliverable | Price per sq ft | |---|---| | Point cloud only (RCP/RCS) | £0.30–£0.80 | | LOD 300 Revit model from laser scan | £1.50–£3.50 | | LOD 350 Revit model (detailed components) | £2.50–£5.00 | | BIM with coordinated ceiling plans (LOD 350+) | £3.00–£6.00 |

For a 1,500m² commercial floor (approximately 16,000 sq ft), expect to pay £25,000–£55,000 for a full LOD 300 BIM deliverable.

London-Specific Pricing

As built survey prices in London are typically 20–40% higher than equivalent UK properties. The London premium reflects:

• Survey team travel time and London congestion/parking costs
• Out-of-hours working surcharges for central London projects
• Higher operational overheads for London-based firms

For a standard 3-bed house in a London borough, expect to pay £700–£1,100 for 2D CAD drawings and £1,200–£2,000 for CAD plus LOD 300 BIM.

How to Get the Best As Built Survey Price

Define your requirements before getting quotes The most common reason for overpaying is commissioning a higher-specification survey than the project actually requires. If you need floor plans for a planning submission, a standard 2D CAD survey is sufficient — you do not need a laser scan and a BIM model.

Use a single firm for multiple properties If you have a portfolio of properties to survey, using one firm across the portfolio gives you volume discounts and reduces administration. For five or more surveys in a single instruction, expect a 15–25% reduction in unit price.

Avoid urgency premiums where possible If your programme allows standard turnaround, you will pay less. Expedited surveys (48–72 hours) typically carry a 25–50% premium. Building the survey into your programme early is the most effective way to control survey costs.

Get a fixed fee, not a day rate Day rate pricing is common for some survey firms but means you bear the risk if the survey takes longer than expected. Fixed fee pricing gives you cost certainty — you know what you will pay before you instruct.

What Is Included in an As Built Survey Price

icelabz prices as built surveys on a fixed-fee basis. Our standard survey fee includes:

• Site attendance by a qualified surveyor
• All measurements using appropriate equipment (total station or laser scan)
• 2D CAD drawings to the specification
• One round of revisions within the scope
• Signed accuracy statement
• PDF and DWG delivery via secure download

BIM deliverables, point cloud data, NIA/GIA measurement schedules, and topographic survey are priced separately. We confirm all costs before instruction.

When Not to Choose the Lowest Price

The cheapest as built survey price is not always the best value. Here is when a low quote should be treated with caution:

When the quote is significantly below market rate If a quote is 30–40% below what you would expect to pay, the firm may be using outdated equipment, quoting on the basis of incomplete information, or planning to cut corners on processing quality. The survey will require more revisions and may ultimately cost more than a properly priced alternative.

When the firm does not specify an accuracy standard RICS measured survey standards (Level 1, 2, or 3) exist to ensure consistency. A firm that does not specify the accuracy standard it is working to may not be working to any recognised standard.

When there is no signed accuracy statement The accuracy statement is your proof that the survey was completed to a professional standard. Without it, you have no recourse if the drawings are inaccurate.

When the turnaround is unrealistically fast A survey firm promising CAD drawings in 48 hours for a large commercial property is either not doing the processing properly or has no work to prioritise. Quality processing takes time.

Frequently Asked Questions

Q: Is there a minimum as built survey price?

Yes. For a standalone residential measured building survey, our minimum fee is typically £400. For commercial properties, minimum fees start at £800. We do not survey below these thresholds because the quality of the survey would be compromised.

Q: Are there discounts for multiple surveys?

Yes. For developers and property managers with a portfolio of five or more properties, we offer volume discounts of 15–25%. Contact us with a schedule of properties for a portfolio quote.

Q: Do survey prices vary by London borough?

There is no systematic price difference between London boroughs. Survey prices in central London are typically higher due to parking and congestion costs, but there is no consistent premium for any particular borough. The property size and type are the primary drivers of price variation.

Q: Can I get a fixed fee quote?

Yes.Icelabzprices all as built surveys on a fixed-fee basis. Provide us with the property address, approximate floor area, and output format required, and we will respond with a fixed fee within one working day.

Q: What is not included in the standard survey price?

Topographic survey, BIM model, point cloud data, and NIA/GIA measurement schedules are priced separately. Revisions outside the scope are charged at our standard day rate. If the brief changes after instruction, we notify you before continuing work.
