We will survey all accessible floors in the property and provide plans showing all visible walls, windows, doors, spot height levels, ceiling/roof heights, window sill/head heights.
A commercial building survey is a dimensional record of an office, retail unit, industrial facility, church or mixed-use asset, produced to support leasing, refurbishment, fit-out, disposal and estate management decisions. It answers a different question to a residential survey: not simply what the building looks like, but how much of it there is, who is responsible for which part of it, and what condition it was handed over in.
XP Surveys captures commercial property to ±2mm and delivers area schedules, demise drawings and as-built information that landlords, tenants, agents, developers and estate teams can rely on in a negotiation. Survey work is planned around the operating building – trading hours, tenant access, permits and security – so the asset keeps working while we record it.
Please note: this is a measured survey, not a building condition survey. We record geometry, areas and as-built configuration. We do not carry out defect inspections, structural assessments or RICS Home Survey reports, and we do not provide valuations.
Why Commercial Property Needs a Different Survey Approach
The measurement technology is the same. The constraints are not. A commercial building is usually occupied, often multi-let, and almost always subject to a lease, a service-charge apportionment or a dilapidations liability that depends on the numbers in the survey being correct and defensible.
- Areas carry money. A demised area that is wrong by two per cent is a rent error repeated every quarter for the length of the term.
- The building stays open. Retail floors trade, offices are staffed and warehouses keep picking. Survey work is sequenced around that.
- Access is controlled. Permits, inductions, escorts, plant rooms, risers, roofs and landlord-only areas all need arranging in advance.
- One dataset, many parties. Landlord, tenant, agent, designer and contractor all work from the same drawings, so the survey has to be neutral and complete.
- Portfolios need consistency. Twenty assets surveyed to twenty different standards cannot be compared. Layering, naming and area conventions are fixed once and applied across the estate.
- Records outlive the project. The survey becomes the reference file for every future lease event and alteration.
Commercial Surveys by Asset Class
What gets recorded, and to what level of detail, changes with the asset type. The table below sets out where the survey effort typically goes.
| Asset Type | Typical Survey Focus | Commonly Driven By |
|---|---|---|
| Offices | Floor-by-floor demise, core and common parts, ceiling voids, riser positions, occupational density | Letting, Cat A and Cat B fit-out, space planning, service charge |
| Retail & Leisure | Unit boundaries, shopfront line, ancillary and back-of-house, ITZA-relevant depths | Rent review, unit reconfiguration, brand rollout, disposal |
| Industrial & Logistics | Clear internal height, column grid, floor-flatness reference, dock and yard geometry, roof structure | Racking design, occupier requirements, extension, acquisition |
| Multi-Let & Mixed Use | Demise separation, shared services, common parts, vertical circulation | Service-charge apportionment, landlord records, asset management |
| Hotels & Serviced Assets | Room-by-room key count, back-of-house, plant, guest circulation | Refurbishment programmes, brand standards, operator handover |
| Estates & Portfolios | Consistent layering, naming and area basis across every site | Portfolio review, disposal programmes, estate-wide records |

Churches, Chapels & Faith Buildings
Churches and faith buildings sit outside the usual commercial categories, but they are managed like an estate – a portfolio of buildings, halls and ancillary spaces held by a parish, diocese, trust or congregation, often let for community use and carrying significant maintenance and insurance obligations. An accurate measured record underpins nearly every decision made about them.
Where a Survey Supports Church Property
- Quinquennial inspections. Church of England buildings are inspected on a five-yearly cycle; an up-to-date measured plan gives the inspecting architect or surveyor a reliable base to work from.
- Reordering and faculty applications. Alterations to consecrated buildings run through the faculty system rather than ordinary consent, and a faculty petition is far stronger with accurate existing-condition drawings.
- Insurance and reinstatement records. Church fabric is frequently irreplaceable, and a dated dimensional record supports reinstatement valuation and post-incident recovery.
What We Capture
- Floor plans of the nave, aisles, chancel, vestries, towers and ancillary rooms
- Church halls, community spaces and lettable areas, with usable floor areas
- Elevations and sections where alteration, access or re-roofing works are planned
- Non-contact laser capture that records the building without touching sensitive fabric
Our role is the measured record itself. Conservation strategy, condition assessment and faculty advice sit with your inspecting architect or heritage consultant – we give them accurate data to work from.
When a Commercial Survey Is Commissioned
Commercial surveys are rarely speculative. They are almost always triggered by a dated event where an accurate record either protects a position or unlocks a decision.
- Letting and re-letting – marketing plans, floor plates and a defensible area schedule before a unit goes to market.
- Lease grant and renewal – demise drawings that define exactly what is being let, coloured and dimensioned for attachment to the lease.
- Rent review – independent area evidence where the parties disagree on the measured extent of the demise.
- Dilapidations – a dated as-built record at lease commencement and a comparison record at expiry, so reinstatement obligations are assessed against fact rather than recollection.
- Fit-out and refurbishment – existing-condition information for designers before Cat A or Cat B works are specified.
- Acquisition and disposal due diligence – verified areas and configuration before an offer is finalised.
- Alteration and licence applications – drawings showing existing versus proposed for landlord consent.
- Estate records – replacing incomplete, inherited or undated drawing sets across a portfolio.
Area Measurement: GIA, NIA, GEA and IPMS
Area is the single most contested number in commercial property, because it is the number the rent is calculated from. Two surveyors measuring the same office to two different standards will legitimately produce two different figures – which is why the basis of measurement has to be agreed before anyone goes to site, and stated clearly on the drawing.
We measure and report to the standard your transaction requires, and we state which one has been used on every area schedule we issue.
| Basis | What It Measures | Typically Used For |
|---|---|---|
| GEA – Gross External Area | The full external envelope of the building | Planning submissions, rating, construction cost planning |
| GIA – Gross Internal Area | The whole enclosed area within the external walls | Industrial and warehouse property, development appraisal, build cost |
| NIA – Net Internal Area | Usable floor space, with columns, cores, plant and circulation excluded | Office and retail lettings, rent review, service charge |
| IPMS – International Property Measurement Standards | A single international basis, reported as IPMS 1, 2 or 3 depending on scope | Cross-border portfolios, institutional reporting, corporate occupiers |
Measurement is carried out in accordance with RICS guidance, and every area schedule states the basis used, the date of measurement, the exclusions applied and the drawing revision it relates to. That audit trail is what makes the figure usable in a negotiation rather than merely indicative.
Where a demise is disputed or unclear on the ground, we can record the physical extent as found and note the discrepancy against the lease plan, rather than silently resolving it. Related boundary questions are covered by our boundary surveys.
Surveying Occupied and Operational Buildings
Most commercial surveys happen in buildings that cannot stop. A trading store, a staffed office floor, a live distribution centre and a running hotel each place a different constraint on when and how work can be carried out. Planning that constraint properly is the difference between a survey that takes two nights and one that takes two weeks of aborted visits.
How We Plan Around Occupation
- Out-of-hours, evening and weekend scanning where daytime access is impractical
- Phased capture floor by floor or unit by unit, so no area is closed for long
- Advance access schedules covering risers, plant rooms, roofs, sub-stations and landlord-only areas
- Coordination with building management, security and tenant representatives before mobilisation
- Discreet working in customer-facing and client-facing space
Site Documentation Provided
- Risk assessments and method statements issued in advance of works
- Permit-to-work compliance, including roof, height or hot-works permits required by the building
- Site induction attendance and sign-in as required by the managing agent
- Insurance certificates supplied on request
- Accreditations:
Scanning is non-intrusive and non-contact. No fabric is opened, no fixings are made and no services are interrupted, which is what makes the method suitable for occupied and sensitive commercial environments in the first place.
Commercial Deliverables
Commercial deliverables are organised around who has to use them. An agent needs a clean marketing plan, a surveyor needs an auditable area schedule, a designer needs a coordinated base drawing and an estate team needs a file that will still make sense in five years.
- Area schedules – floor-by-floor and unit-by-unit, stated to an agreed basis of measurement.
- Demise and lease plans – coloured, dimensioned and drawn for attachment to legal documentation.
- Marketing floor plans – simplified plans for agency particulars and letting brochures.
- As-built base drawings – coordinated existing-condition plans, elevations and sections for design teams.
- Space and occupancy plans – layouts prepared for stacking, blocking and workplace planning.
- Dated condition record – a fixed point-in-time capture retained as evidence for later comparison.
Output formats, drawing scales and layering conventions follow the same standards as every project we deliver – full detail is on our measured building survey page. Where a full 3D model is required, commercial projects commonly progress to Scan-to-BIM.
Programme is confirmed at quotation. Commercial buildings vary too widely in size, occupation and access for a single published turnaround to be meaningful, so we agree a delivery date against the actual scope before work is instructed.
Survey Data and Building Compliance Records
Regulatory expectations around building information have moved decisively towards accurate, current and traceable records. For commercial estates that has a practical consequence: undated drawings of uncertain provenance are becoming harder to rely on, and a verified as-built capture is increasingly the starting point for a compliant building record rather than an optional extra.
A measured survey supplies the geometric layer of that record – verified dimensions, configuration and areas, captured on a known date. How that data is then structured, maintained and handed over is covered by our digital building records service.
How Commercial Surveys Are Priced
Commercial work is individually quoted. Published price bands exist for standard residential property because the variables are narrow; on a commercial asset they are not. Two buildings of identical floor area can differ by a factor of three in survey cost depending on occupation, access and the level of detail required.
The variables that actually move a commercial fee:
| Cost Driver | Why It Moves the Fee |
|---|---|
| Floor area & storeys | The baseline, but rarely the deciding factor on its own |
| Occupation | Whether the building is empty, partially let or fully trading |
| Working hours | Daytime access versus evening, night or weekend capture |
| Access complexity | Escorted areas, permits, plant rooms, risers, roof access, access equipment |
| Level of detail | A marketing plan and a fully coordinated Cat B base drawing are very different scopes |
| Area certification | Whether a formal area schedule to a stated basis is required |
| Number of sites | Portfolio and rollout work is priced differently to a single instruction |
For a fixed written fee, send the address, approximate floor area, the deliverables you need and any access constraints. Quotations are issued as a fixed price against a defined scope, not an hourly estimate.
Commercial Projects
Greenpeace UK Headquarters, Islington
A full measured survey of an operational headquarters building including office space, warehouse areas and plant rooms. High-density capture was completed on site over two days using the Trimble X7, giving the design team a verified existing-condition foundation for a complex refurbishment in a live, occupied building.
Former Commercial Building, London Road, Twickenham
A complete internal and external measured survey of a five-storey commercial property of just over 6,000 sq ft, supporting a planning application for conversion to residential use. The survey provided the architect and planning team with accurate existing-condition drawings for a change-of-use scheme.
Further examples are available in our case studies.

Commercial Survey FAQs
Is a commercial building survey the same as a building condition survey?
No. A commercial measured survey records dimensions, layout and areas. A building condition survey assesses defects, deterioration and repair liability, and is carried out by a building surveyor. The two are frequently commissioned together on an acquisition, but they are separate pieces of work and we provide the measured element only.
Can you survey while the building is occupied and trading?
Yes. Most of our commercial work is carried out in occupied buildings. Capture is non-intrusive and can be phased, carried out out-of-hours, or sequenced floor by floor so occupation continues uninterrupted.
Which measurement standard will you use?
Whichever the transaction requires – GEA, GIA, NIA or IPMS. The basis is agreed before we attend site and stated explicitly on the area schedule and drawings, so the figure can be relied on and audited later.
Can you produce drawings suitable for attaching to a lease?
Yes. Demise and lease plans are produced coloured and dimensioned to the extent you specify. We prepare the drawing to instruction; confirming that the demise shown reflects the legal position is a matter for your solicitor or surveyor.
Do you survey churches and other faith buildings?
Yes. We provide measured plans, elevations and sections for churches, chapels, halls and ancillary buildings, supporting quinquennial inspections, reordering and faculty applications, and insurance reinstatement records. We supply the measured data; conservation and faculty advice rests with your inspecting architect.
Do you work across multiple sites and portfolios?
Yes. Portfolio instructions are set up with fixed layering, naming and area conventions applied to every asset, so drawings from different sites remain directly comparable. Rollout programmes are scheduled and priced as a single instruction.
Do you cover the whole of the UK?
Yes – we work on commercial property throughout the UK from our base in Henley-on-Thames.
