Tell us your postcode and requirements when you enquire so we can discuss coverage and the appropriate service.

Structural engineer in North London

Loft conversions, rear extensions and changes to internal walls are among the projects covered by our North London structural engineering service. These alterations may require assessment of the existing structure alongside calculations and drawings for proposed work. The local guide explains the engineer’s role, the information a report can provide and how the scope of an instruction is established.

Structural engineer in East London

Our East London page brings together advice on structural reports and engineering support for residential alterations. If you have noticed cracking or sagging, or a surveyor has recommended further investigation, a focused inspection can address the specific concern. For planned works, the service also includes structural drawings and load calculations, with the required input agreed around the project.

Structural engineer in South London

A property purchase, refinancing requirement or planned extension can raise different structural questions. Our South London guide explains the inspection and reporting service, including assessment of accessible load-bearing elements and recommendations for further action. It also outlines engineering support for alterations such as new openings, wall changes and loft conversions, helping you distinguish an existing-condition report from design work.

Structural engineer in South East London

Our South East London coverage includes Greenwich, Lewisham, Bromley and Bexley, as well as Catford, Forest Hill, Dulwich, Eltham and Sidcup.

Use it to explore the service relevant to your property before requesting a quotation.

Structural engineer in South West London

Our South West London service includes engineering input for extensions, loft conversions, modified openings and chimney-breast removal. The regional page also explains inspections where an existing defect or a survey referral needs closer assessment. The engineer’s input can form part of your wider project team, with reports, calculations and drawings commissioned to suit the agreed brief.

Structural engineer in West London

For a West London home, you may need an engineer to investigate a concern or develop structural information for proposed alterations. Our local guide covers both routes, including focused inspections, drawings and calculations.

How can our residential structural engineers help?

Structural inspections and reports

A structural inspection focuses on the concern set out in your brief. This may follow a survey recommendation or relate to cracking, movement or an altered part of the building. The engineer considers the accessible structure and the information provided, then reports on the agreed issues. Where the cause cannot be established from the inspection alone, further investigation may be recommended. Opening-up, testing or monitoring should be agreed separately where required.

Alterations, extensions and conversions

Removing or modifying a wall, forming an opening, extending a home or converting a loft can affect the way the building carries loads. Engineering input helps assess the structural implications of your proposals. Tell us what you want to change and share any architectural drawings available. We can discuss the relevant assessment and design work, together with the information that your architect, contractor or building control team may need.

Structural calculations and drawings

Calculations and structural drawings serve a different purpose from an inspection report. They set out engineering information for an agreed design brief, such as the structural elements needed for proposed alterations. The required documents depend on the project and the responsibilities of the professionals involved. Read our guide to engineering calculations in London, or send us your proposals so we can discuss the work required.

Following up a building survey

If a surveyor has recommended a structural engineer, send us the relevant report extract rather than relying on a short summary. The recommendation may concern one element or a wider pattern of movement. Understanding the original observations helps us identify the question to be addressed. Where your concern relates to a single building defect, our specific defect report service may also be relevant.

Do you need a structural engineer or a building surveyor?

A Level 3 Building Survey considers a property's overall condition and is often relevant when buying an older, altered or complex home. A structural engineering instruction usually addresses a defined structural concern or provides design input for proposed work. The services can complement each other, but their scope and deliverables differ.

If you are unsure, explain what you need to achieve. We can discuss the appropriate starting point, including whether a survey, focused defect report or engineering assessment is suitable. For concerns specifically involving ground movement, you can also read about our subsidence survey service.

Engineering expertise

Structural engineering within Harding

Harding brings together surveying and engineering expertise, helping clients understand which professional input their property needs. Alaa Ali, a Chartered Civil/Structural Engineer, has experience in structural design, inspections and building defects. Read his profile to learn more about his background. When you enquire, we will discuss the expertise required for your instruction and how the engineering work relates to any other surveys or professional advice you already have.

How much does residential structural engineering cost?

The fee depends on the property, the complexity of the issue or proposed works, access, available information and the documents required. An inspection and report is a different instruction from a package of structural design calculations and drawings. Further visits, investigations or revisions may also affect the scope.

Request a quotation based on your requirements. Before proceeding, check what is included, whether VAT applies, what information you need to supply and how any additional work would be agreed.

Your structural engineering questions

What should I send with my enquiry?

Include your postcode, a description of the concern or proposed work, and relevant photographs, survey extracts or drawings. Tell us if another professional or organisation has requested particular documents.

Will a report include structural calculations?

Only where calculations form part of the agreed scope. An inspection report and a design package have different purposes, so we confirm the deliverables before you instruct us.

Can you advise before I start renovation work?

Yes. Contact us while your proposals are being developed so we can discuss the structural engineering input required and the information needed from you or your designer.
