Find a structural engineer for your project
Removing a wall, adding a beam, extending, converting a loft or worried about a crack? Structural engineers who are interested get in touch with a quote.
A structural engineer works out how a building stands up. They design the beams, foundations and supports for your project, prepare the calculations and drawings that Building Control asks for, and investigate cracks, movement and other structural worries.
Describe your project once. Engineers who are interested connect with you, so you can compare their profiles, experience and quotes in one place before you choose.
What structural engineers do
- Design steel beams (RSJs) and supports for removing or altering walls
- Prepare structural calculations and drawings for Building Control
- Design foundations, underpinning and retaining walls
- Design the structure for extensions, loft conversions and new buildings
- Investigate cracks, movement and subsidence and report on what to do
- Inspect the work on site and confirm it was built as designed
When you need one
- You want to take out a load-bearing wall or chimney breast
- You are building an extension or converting a loft
- Building Control has asked for structural calculations
- You have seen cracks, sloping floors or signs of movement
- You are buying a property and want its structure checked

Where they work
Structural engineers on the marketplace cover the whole of the UK, and many can work from drawings and photographs before a site visit.
Checking credentials
Many structural engineers are chartered through the Institution of Structural Engineers (IStructE) or the Institution of Civil Engineers (ICE). On this site a chartered title such as “Chartered structural engineer” is shown only after our team has checked the membership. Other professionals appear as structural engineers.
Questions people ask
When do I need a structural engineer?
Typically when you remove or alter a load-bearing wall, add a beam, build an extension, convert a loft, change foundations or dig a basement, or when you see cracks or movement. Your council’s Building Control may ask for the calculations.
What will a structural engineer give me?
Usually calculations and drawings that show the size and position of beams, supports and foundations, in a form that Building Control and your builder can use. Some also inspect the work and confirm it was built as designed.
What is the difference between a structural engineer and an architect?
An architect designs how a building looks, feels and works. A structural engineer designs how it stands up. Many projects need both, and they often work together.
How do I check a structural engineer?
Ask whether they are chartered through IStructE or ICE, whether they hold professional indemnity insurance, and which projects like yours they have done. Compare what each quote includes, such as site visits and revisions.
Can an engineer help if I have cracks in a wall?
Yes. An engineer can inspect, record how much the crack moves and tell you whether it needs repair, monitoring or further investigation, in a short report you can show a buyer, lender or insurer.
