Structural inspection reports

A structural inspection report turns what an engineer sees on site into a written conclusion you can act on or hand to a third party. We write reports that stand up with lenders, insurers and building control across the UK.

How we work

What is a structural inspection report?

It is a written document from an engineer that records a site inspection, diagnoses the cause of any defect or movement, states how serious it is, and sets out what should be done. It is the record a lender, insurer, buyer or building control officer relies on.

In detail

What a good report contains

A report is only useful if the reader can act on it. Ours set out the scope and limitations, the construction and history of the building, what we observed, and then the part everyone actually needs: the diagnosis. We say what is causing the problem, whether it is still moving, how serious it is, and what if anything should be done, with a sensible order and rough scale for the works. Photographs are annotated so a non-engineer can see exactly what we mean.

We are careful to separate observation from opinion, and to be honest about what we could not see. A crack behind plaster, a foundation under the ground or a wall plate hidden by a ceiling all limit what a visual inspection can conclude. Where that matters, we say so and recommend the specific next step rather than padding the report with caveats that leave the reader no wiser.

Reports for different readers

The same building can need very different reports depending on who is reading. An owner wants plain language and a clear steer on whether to worry and what to spend. A buyer and their solicitor want something that supports a decision or a renegotiation. A lender wants a specialist to confirm the property is adequate security and to state whether movement is progressive. An insurer handling a subsidence claim wants cause established against their policy wording, often with monitoring or drainage evidence.

We tailor the emphasis to the audience without changing the engineering. The findings are the same; what varies is how much technical detail sits in the body versus a summary, and which questions we answer head on. For validation, warranty or dispute work we keep the tone factual and the reasoning transparent, because those reports may be read by other engineers or relied on in a claim.

From inspection to written conclusion

The inspection and the report are one job, not two. On site we gather the evidence that the report will rest on: crack widths and locations, floor and wall levels, the pattern of movement, moisture readings, and the condition of key structural elements and their junctions. Where capacity is in question we take the measurements needed to run calculations afterwards, so the written conclusion is backed by Eurocode checks rather than a general impression.

We aim to turn reports around promptly, typically within a target window we agree at the outset, because these reports usually sit on a transaction or a claim with its own timetable. For European instructions we can prepare the desktop assessment and reporting remotely and coordinate a local visit where physical access is essential.

Scope of an inspection. Inspections are carried out within the scope and limitations set out in the fee proposal and stated in the report. Unless expressly agreed otherwise, an inspection covers what is reasonably accessible at the time and is not a warranty that every defect, deterioration or concealed condition has been identified. Where something cannot be seen, we say so and set out what would establish it.

2

Information

We agree the survey, drawings or data we need and any site access required.

3

Engineering

Design, calculation or assessment to the relevant Eurocodes and UK National Annex.

4

Issue

A clear, defensible report or set of calculations, with assumptions and limitations stated.

Questions

Common questions

What is a structural inspection report?

It is a written document from an engineer that records a site inspection, diagnoses the cause of any defect or movement, states how serious it is, and sets out what should be done. It is the record a lender, insurer, buyer or building control officer relies on.

How quickly can I get the report?

We aim to issue reports promptly, typically within a target window agreed when you instruct us. Because reports often sit on a house sale or an insurance claim, we plan the visit and writing around that deadline where we can.

Will the report say whether the cracking is serious?

Yes. That is the point of it. We classify the significance, state whether the movement is still active or long finished, and say plainly whether it needs repair, monitoring or nothing at all, rather than leaving you to interpret a list of observations.

Can you write a report my insurer will accept for a subsidence claim?

Yes. For claims we establish cause against the situation on the ground, note where monitoring or drainage investigation is needed, and keep the reasoning transparent so it holds up when the insurer's own engineer reads it.

Do you charge a fixed fee for reports?

Our inspection reports start fixed once we know the property and the concern. A single-defect report is at the lower end; a wider appraisal with calculations costs more.
