What does a commercial building survey report actually include?

Commissioning a commercial building survey is one thing. Understanding what comes back is another. In the latest Bressummmer A.R.K guide we explain what a commercial building survey report actually contains, section by section, so that landlords and tenants know what they’re receiving and how to use it.

Commercial Building Survey Reports

When clients receive a commercial building survey report, the first thing that often surprises them is how much is in it. A thorough report on a mid-sized commercial property can run to 80 pages or more. For someone who hasn’t seen one before, that volume can feel difficult to navigate.

The second thing that sometimes surprises people is that it isn’t just a list of defects. A commercial building survey report covers condition, yes, but it also addresses compliance, liability, future maintenance and the wider context of whatever transaction or decision prompted the instruction. Understanding what each section contains and what you’re supposed to do with it, makes the document considerably more useful.

Our objective with this guide it to walk you through the typical structure of a commercial building survey report and explain what each part is actually for. Enjoy!

The Scope and Basis of the Inspection

Before the surveyor reports on anything they found, a well-structured report sets out clearly what they were asked to do, what they actually inspected and what fell outside the scope of their inspection.

This section matters more than it might appear. Commercial building surveys are bespoke. The scope is agreed between client and surveyor at the point of instruction. A survey commissioned to support a leasehold acquisition will have a different emphasis to one commissioned as part of a freehold purchase or ahead of a refurbishment. The report should make clear which scenario applies.

It will also note any limitations on the inspection; areas that couldn’t be accessed, elements that were concealed or aspects that require specialist investigation beyond the scope of a building surveyor. A roof hidden beneath a suspended ceiling, an electrical installation that needs a qualified engineer to properly assess or a drainage system that can only be properly checked by a CCTV survey are all examples of things that a surveyor will flag rather than assume.

Knowing what the report covers, and what it doesn’t, is the starting point for understanding how to use it.

Executive Summary

Most commercial survey reports include an executive summary near the front of the document. Its purpose is to give a quick, readable overview of the principal findings without requiring the reader to work through every section before forming a view.

A good executive summary will identify the most significant issues found, give a sense of the overall condition of the property and flag any items that need urgent attention or that should influence the transaction. It is not a substitute for reading the full report, but it is a useful navigation tool, particularly if you’re sharing the report with a solicitor, a lender or another professional who needs to understand the headlines quickly.

Property Description and Background

Before getting into condition, the report will describe the property; its construction type, age, size, layout and general nature. This section provides the context within which everything else is assessed.

Construction type matters because it affects what the surveyor is looking for and how they interpret what they find. A steel-framed warehouse from the 1980s presents different risks from a Victorian brick office building or a 1960s concrete-framed retail unit. The background section helps the reader understand why certain issues have arisen and what the implications are for a building of that type and age.

Structural Frame and External Envelope

This is the core of most commercial building survey reports: the physical inspection findings, working systematically through the building from the outside in.

The structural section covers the main frame of the building; whether that’s load-bearing masonry, steel or concrete frame, timber structure or some combination and its general condition. Surveyors are looking for movement, cracking, deterioration and anything that suggests the structure isn’t performing as it should.

The external envelope covers everything that forms the skin of the building: walls, cladding, roof coverings, windows, doors, gutters and downpipes. These elements are the building’s first line of defence against water ingress, and water ingress is the source of a significant proportion of the defects found in commercial buildings. The condition of the external envelope is therefore given considerable attention.

At Bressummer A.R.K., we include drone inspection of roofs as standard on every commercial building survey. This gives us direct visual access to roof coverings, junctions, flashings and drainage outlets that would otherwise be seen only from ground level or not at all without expensive temporary works. The findings from the drone inspection are incorporated into this section of the report.

Internal Condition

Working through the interior of the building, the report covers floors, internal walls and partitions, ceilings, internal doors and finishes. The level of detail varies depending on the nature of the property and the purpose of the survey, but the surveyor is broadly looking for signs of defects, deterioration and anything that suggests problems elsewhere in the building.

Damp patches on walls or ceilings, for example, tell a story about the external envelope or drainage. Uneven floors may indicate movement in the structure below. Staining around service penetrations might point to plumbing issues above. Internal condition findings are often as useful for what they reveal about the building’s wider performance as for the specific items they describe.

Building Services

Building services, such as heating, ventilation, air conditioning, plumbing, drainage and electrical systems, are typically addressed in a commercial building survey report at a general, visual level. The building surveyor comments on what they observed: the apparent age and condition of systems, whether they appeared to be operating, any obvious deficiencies and whether specialist investigation is recommended.

A full mechanical and electrical survey is a separate exercise, carried out by qualified engineers and may be recommended as a follow-up where the services are complex, aging or critical to the intended use of the building. For many commercial acquisitions, particularly larger ones or those involving significant M&E systems, a specialist M&E report alongside the building survey is best practice.

The survey report will indicate clearly where it considers specialist follow-up to be warranted, so the client can decide whether to commission it before or after exchange.

Statutory Compliance

This section covers the regulatory framework that applies to the building and highlights where compliance issues exist or where further investigation is needed.

The main areas addressed are typically:

Asbestos.
For any building constructed before 2000, the report will address whether an Asbestos Management Survey exists, whether it appears to be current and whether any asbestos-containing materials were observed. Where an up-to-date survey doesn’t exist, the report will recommend that one is commissioned before proceeding.

Energy Performance.
The EPC rating will be noted and, where it is poor, its implications for the transaction or occupation will be discussed. This is increasingly significant given the direction of MEES legislation for commercial property.

Fire safety.
The apparent provision of fire detection, suppression and means of escape will be noted, along with any obvious deficiencies. Where a formal fire risk assessment is absent or clearly out of date, the report will flag this.

Disability access.
The Equality Act 2010 places obligations on those who occupy and operate commercial premises. The report will identify significant access limitations and, where appropriate, recommend a more detailed access audit.

Planning compliance.
Where works appear to have been carried out that may have required consent, the report will note them so that the solicitor can investigate the planning and building regulations position.

Deleterious Materials

Separate from the asbestos section, the report will address the presence of other materials that have been identified as potentially harmful or problematic. This will include things like high alumina cement concrete (HAC), calcium chloride additives, mundic block, or certain forms of cavity wall insulation used in commercial construction from particular periods.

Many of these are specific to particular construction types or eras. The surveyor will identify where these are a plausible risk based on the building’s age and construction and, where relevant, recommend further investigation.

Repair and Maintenance Recommendations

Having worked through the building, the report sets out a schedule of recommended repairs and maintenance works. This is one of the most practically useful sections of the report for most clients.

The schedule typically categorises items by urgency:

Urgent or immediate
Items that pose a safety risk, are causing active damage, or need attention before occupation or completion. These might include structural problems, live water ingress or compliance failures that need to be resolved before the building can be safely used.

Short-term
Items that don’t require immediate action but should be addressed within the near term, typically within one to two years, to prevent deterioration or more costly remediation later.

Longer-term or cyclical
Items that are functioning but aging, where expenditure should be planned for over the medium to long term. This section bridges into the territory of a PPM schedule for clients who want a full forward maintenance plan.

Where instructed, the report will also include budget cost estimates against individual items or categories of work, to give the client a financial sense of what the repair and maintenance liability looks like.

Lease-Specific Advice

For leasehold acquisitions, a good commercial building survey report goes beyond physical condition to address the transaction in context. This includes commentary on:

• The repairing obligations the client is taking on under the proposed lease and how the current condition of the building maps onto those obligations
• Whether a Schedule of Condition should be prepared to limit future dilapidations liability
• Any items that should be addressed in the negotiation of the lease or the heads of terms
• The interaction between the survey findings and the proposed rent, lease length, and break options

This part of the report is where the surveyor earns their keep as a commercial adviser rather than simply a building inspector. The condition of the building only tells part of the story. How the lease is structured, and how the client’s obligations are framed, determines what that condition actually means for their financial exposure.

What to Do With the Report

A commercial building survey report is a working document, not a filing exercise. The most useful thing a client can do after receiving one is read it carefully, identify the items that matter most to their specific situation and use the findings to inform what happens next.

In practice, that usually means one or more of:

• Sharing the report with their solicitor so that legal due diligence and survey findings are considered together
• Using the repair schedule as the basis for a price renegotiation or a request for landlord works ahead of lease commencement
• Commissioning follow-up specialist reports on items flagged as requiring further investigation
• Using the budget cost estimates to inform financial planning for the acquisition
• Instructing the preparation of a Schedule of Condition before lease completion

Receiving a survey report is not the end of a process. It is, in most cases, the point at which the most important decisions of a transaction get properly informed.
