Structural Engineer in South East London
Harding Chartered Surveyors provides independent structural engineering inspections and reports across South East London, led by our in-house structural engineer, a member of the Institution of Civil Engineers (ICE). South East London sits on the thickest London clay deposits in the capital — which makes it the part of London most affected by subsidence. If you own a period home in Greenwich, Lewisham, Bromley or Dulwich, movement and cracking aren't rare events; they're the predictable result of a century of shallow Victorian foundations riding the clay's shrink-swell cycle. That's why our structural engineering work in this part of London so often begins with a crack.
From our Bexley office and others nearby we cover Greenwich, Lewisham, Bromley, Bexley, Catford, Forest Hill, Dulwich, Eltham and Sidcup — usually with an inspection available within a few working days.
When you need a structural engineer in South East London
South East London's housing is dominated by Victorian and Edwardian terraces with shallow foundations, interwar semis on the outer fringes, and a growing number of warehouse and industrial conversions around Forest Hill and Deptford. That mix produces a recognisable set of structural issues:
- Clay-related subsidence and seasonal cracking, especially near mature trees
- Diagonal stepped cracking around bay windows on shallow-founded terraces
- Movement in single-skin rear additions and original outrigger structures
- Ring-beam and steel-frame questions in warehouse and industrial conversions
- Spreading roofs and failed wall ties in older terraced stock
Structural engineer or building survey?
If you want a general assessment of a property's overall condition before buying, that's a RICS Level 3 Building Survey or a structural survey. If you have a specific structural concern in South East London — a crack, a wall to remove, a subsidence worry, an extension to design — that's a job for a structural engineer. Not sure which you need? Call us and we'll point you the right way, even if it's the cheaper option.
Has your survey flagged a structural problem?
If a homebuyer report or building survey on a South East London property has flagged cracking, movement or a "further investigation recommended" note, that's exactly when a structural engineer takes over. Because Harding provides both the survey and the structural engineering under one roof, we can move straight from the flag to a specialist assessment — telling you whether the issue is serious, what it will cost to put right, and how it should affect your offer. That continuity saves you the delay and expense of briefing a separate firm mid-purchase.

Subsidence and clay movement in South East London
The London Basin's clay layer reaches its deepest point beneath the south and east of the city. Greenwich, Lewisham, Catford, Forest Hill, Brockley, Peckham, Dulwich, Eltham and Sidcup all sit on substantial clay, and many pre-1914 terraces here were built on foundations just 300–600mm deep — perfectly normal for their time, but vulnerable to seasonal ground movement. In a dry summer the clay shrinks and cracks open up; in winter it swells back. A structural engineer can tell you whether what you're seeing is active subsidence needing intervention, or historic movement that has long since stabilised — a distinction that makes an enormous difference to cost and to a sale.
What our structural engineer provides
- Structural inspection reports on a specific defect — a clear written assessment of the problem, its likely cause, and the recommended remedy.
- Structural calculations and drawings for load-bearing wall removal, extensions, loft conversions and new openings — everything Building Control requires.
- Subsidence and crack assessments, including whether monitoring, underpinning or simpler repairs are appropriate.
- Expert opinion where a structural issue affects a purchase, an insurance claim or a dispute.
- Certificates of adequacy confirming completed structural works, as often required for insurance or re-mortgaging.
Every report is produced by a qualified engineer, not a generalist — the same independent, jargon-free standard Harding has provided since 1997.

Costs depend on the size and complexity of the job.

Recent Reviews from Harding Chartered Surveyors
Frequently asked questions
Is subsidence really worse in South East London?
Yes — South East London sits on some of the thickest and most shrinkable clay in the London Basin, which is why it's the area of the capital most associated with subsidence claims. That doesn't mean every property is affected, but it does mean movement here is worth taking seriously and assessing properly rather than ignoring.
Do I need a structural engineer to remove a load-bearing wall?
Yes. Removing a load-bearing wall requires structural calculations and a beam (RSJ) design that Building Control will need to approve. We provide the calculations and drawings your builder needs.
I've got cracks in my wall — should I worry?
Many cracks are cosmetic, but some signal movement that needs attention. Diagonal cracks around doors and windows, cracks wider than about 5mm, or cracks that are visibly widening are worth assessing. Our engineer can tell you quickly whether it's serious.
How quickly can you inspect my property in South East London?
From our Bexley office and others nearby, we can usually arrange an inspection within a few working days, with the written report following shortly after.
My survey flagged a structural issue — what happens next?
Bring us the report and our engineer will assess the flagged issue directly. Because we carry out both surveys and structural engineering, we can move straight to a specialist opinion — confirming how serious it is, what the remedy involves, and how it should affect your purchase.
Can you provide a certificate of adequacy after works?
Yes. Once structural works are complete, we can inspect and, where appropriate, issue a certificate of adequacy — commonly needed for insurance or re-mortgaging purposes.
