Structural engineer report cost in the UK: what you are paying for

Updated

The engineer's report is the first professional step and the one stage with a reasonably predictable price. Here is what sits inside the fee and what gets billed on top.

What the fee normally buys

  • A site visit and visual inspection of the affected elevations, internally and externally, usually one to three hours on site for a normal house.
  • A written report setting out what the engineer observed, the likely cause or causes, and what should happen next.
  • An opinion on whether movement is progressive, which is the question a lender, a buyer or an insurer actually wants answered.
  • Recommendations, which for an unresolved case usually means monitoring rather than an immediate repair specification.

Typical 2026 quotes for that package sit around £300–£800 for a standard domestic property, with region, property size and the depth of report all moving it. That is a market range we see quoted rather than a published rate, so treat it as a budgeting figure and get two or three actual quotes.

What is not in the fee

Trial pits and soil sampling
Excavating to expose the foundation and taking soil samples for laboratory testing are separate operations with their own cost, usually only commissioned once the inspection points at ground movement.
Monitoring
Repeated level or crack readings over months, plus the closing interpretation. Priced by visit count and interval. See investigation and monitoring.
Drainage survey
A CCTV survey of the drains, often the single most useful early test where movement is localised near a drain run.
Repair design and supervision
Designing and specifying any remedial scheme, and inspecting the contractor's work, are separate professional services.

Comparing two quotes without comparing two different things

  1. Ask each engineer what the written output actually is. A one-page letter of opinion and a full report with photographs, crack mapping and a recommended sequence are not the same product at the same price.
  2. Ask whether a return visit is included. Many cases need the engineer back once monitoring data exists, and whether that is inside the fee changes the comparison.
  3. Ask who the report is addressed to. A report a lender or insurer will accept sometimes needs to be prepared on a particular basis, and retro-fitting that is not free.
  4. Check the engineer's professional indemnity cover and registration. Chartered status is held through bodies such as the Institution of Structural Engineers or the Institution of Civil Engineers, and surveyors through RICS.

If you hold buildings insurance and suspect subsidence, speak to your insurer before commissioning a report. Investigation is normally handled through the claim, and paying for your own report first does not always mean the insurer will rely on it. We do not give insurance advice and we do not recommend insurers.

Questions, answered directly

How much does a structural engineer's report cost in the UK?

For a standard domestic property, typical 2026 quotes for a visual inspection and written report are around £300–£800, varying by region, property size and how detailed the report needs to be. Trial pits, soil testing, monitoring and drainage surveys are quoted separately.

How long does a structural engineer report take?

The site visit is usually a single appointment of a few hours. The written report commonly follows within one to two weeks, though engineers set their own turnaround and a busy practice may take longer. What takes months is not the report but any monitoring period the report recommends.

Is a structural engineer's report worth it?

It is the standard way to get an independent, qualified opinion on whether cracking is progressive movement or something benign such as thermal or shrinkage cracking. For a purchase, a lender query or an unexplained crack that is getting wider, it answers the question that a general homebuyer survey usually only flags.
