Commercial Building Survey & Pre-Acquisition Survey

A commercial building survey is a detailed inspection of a commercial property that identifies defects, repair liabilities and maintenance risks before you buy, take on a lease, refinance or plan works. Sterlingworth Surveyors provides clear, prioritised commercial surveys for investors, owners, landlords and occupiers of office, retail, industrial and mixed-use property.

What is a Commercial Building Survey?

A commercial survey is a professional inspection of a building’s structure, fabric and visible services. It identifies defects and deterioration and explains what they mean for your repair obligations, your budget and your use of the building.

The inspection is typically visual and non-invasive, covering the areas that are safe and reasonably accessible. As an RICS-regulated firm (Firm Registration Number 850747), our work follows current RICS professional standards and guidance.

What Is a Commercial Survey?

When Do You Need a Commercial Building Survey?

The best time is before a decision that commits you to a building’s condition.

Buying or investing

A pre-acquisition survey shows the building’s condition and likely repair liabilities before you exchange, while you can still renegotiate or walk away.

Taking a lease

Many commercial leases make the tenant responsible for repairs, and some require the building to be handed back in good repair whatever its condition at the start. A survey before you sign shows what you could be taking on.

Refinancing or reviewing a portfolio

Owners and investors use condition surveys to understand an asset before refinancing, a sale or a portfolio review.

Planning maintenance or refurbishment

Landlords and owner-occupiers use surveys to prioritise repairs, plan maintenance and budget for capital works.

Types of Commercial Survey We Provide

Each commercial property survey is tailored to the building and to the decision you need to make.

Condition Surveys

A comprehensive assessment of the building’s overall condition, covering the structure, external and internal elements and visible services.

Pre-Acquisition Surveys

Detailed inspections for buyers and investors that identify defects, risks and future maintenance liabilities before purchase.

Planned Maintenance Surveys

Surveys that support long-term maintenance planning, the prioritisation of works and budgeting.

Specific Defect Surveys

Targeted inspections of a particular issue, such as damp, movement, roofing or structural concerns.

Pre-acquisition due diligence

Pre-Acquisition Surveys and Due Diligence

When you buy a commercial property, the building’s condition is part of the price. A pre-acquisition survey helps you:

It does not replace legal, environmental or valuation advice; it is the part of due diligence that looks at the building itself.

Who Should Instruct a Commercial Survey?

What a commercial building survey covers

The scope is agreed for each building before the inspection. A commercial building survey typically looks at the areas that are safe and reasonably accessible, including:

Roofs and rainwater goods

Roof coverings, flat roof finishes, flashings, gutters and downpipes, and visible roof structure where there is safe access.

External walls and structure

Walls, cladding, windows and external doors, and visible signs of structural movement, cracking or deterioration.

Internal areas

Floors, ceilings, partitions, internal doors, staircases and finishes, including signs of damp, leaks or wear that point to wider problems.

Building services

A visual inspection of heating, ventilation, air conditioning, electrical, lighting and plumbing installations, commenting on their apparent age and condition. Services are not tested.

External areas

Car parks, yards, boundaries, surface drainage and outbuildings that form part of the property.

Risks to safety, compliance and use

Visible issues that may affect safety, compliance or the ongoing use of the building, flagged so you can take specialist advice where it is needed.

Does NOT Include

What A Commercial Survey Does not Include

So that expectations are clear from the start, a commercial building survey does not include:

Where something cannot be seen but the surrounding evidence suggests a risk, the report says so and recommends what to investigate further.

Legal duties the survey can flag

A survey is not a compliance certificate, but it can flag visible issues on which you should take specialist advice, including:

What Your Commercial Survey Report Includes

A commercial survey report is written for business use: structured, clear and practical. It typically sets out:

If anything in the report is unclear, you can discuss it with us.

When Should You Arrange a Commercial Survey?

Commercial Surveys, Schedules of Condition and Dilapidations

A commercial building survey assesses the condition of a building and gives advice: what is wrong, how serious it is and what to do about it.

A schedule of condition is a factual record, usually with photographs, of a building’s condition at a point in time, most often at the start of a lease. Depending on how the lease is worded, it can be used to limit a tenant’s repairing obligations by reference to that recorded condition.

Dilapidations are breaches of the repairing, reinstatement or maintenance obligations in a commercial lease. They are usually dealt with at the end of the lease or at a break, when the landlord’s and tenant’s liabilities are assessed and negotiated.

If you are about to take a lease, a survey tells you what you may be responsible for, and a schedule of condition can help protect you later. If a lease is ending, you need dilapidations advice instead.

Is a Commercial Survey the same as a valuation?

No. A commercial survey assesses a building’s condition and the risks that come with it. A valuation gives a professional opinion of what the property is worth. Many buyers and owners need both.

If you need a figure for a purchase, sale, lending or financial reporting, you need a commercial property valuation. A rent review is separate advice again, based on rental evidence rather than condition.

Commercial Building Survey FAQs

What does a pre-acquisition survey include?

A pre-acquisition survey inspects the building’s structure, fabric and visible services before you buy. It identifies defects, repair liabilities and future maintenance needs, flags risks to safety, compliance or use, and recommends any further investigations to complete before exchange.

Yes, in most cases. As a buyer, you take on the building’s condition once you complete. As a tenant, many commercial leases make you responsible for repairs, sometimes beyond the condition the building was in when you moved in. A survey before you commit shows the liabilities while you can still negotiate.

The survey looks for visible defects across the roof, external walls, structure, internal areas, building services and external areas. Where a defect cannot be fully assessed visually, the report recommends further investigation.

It depends on the size, complexity and use of the building, and on access. We confirm the inspection arrangements and when to expect your report when you instruct us.

Yes. Surveys can be carried out on occupied properties, subject to access arrangements with the occupier. Furniture, stock and fittings can limit what is visible, and the report records any areas that could not be inspected.

Yes. A specific defect survey is a targeted inspection of a particular concern, such as damp, movement, roofing or a structural issue, when you do not need a full condition survey.

A survey can highlight visible issues that may affect compliance, such as possible asbestos-containing materials or fire safety concerns, so you can take specialist advice. It is not a compliance certificate and does not replace statutory testing, an asbestos survey or a fire risk assessment.
