Appointing a structural engineer in Cambridge
Cambridge engineers mainly design steels for rear extensions and knock-throughs, loft floors, and foundation solutions on shrinkable clay with mature trees nearby — the single most common complication locally.
Property you'll be working with in Cambridge
Gault brick Victorian terraces, interwar and post-war housing, and newer estates. Tree-related clay movement is a frequent cause of both crack reports and deeper foundation design.
Planning in Cambridge
Calculations are submitted with your building regulations application. Where protected trees are close to the works, foundation design and a tree report usually have to be resolved together.
What structural engineers charge in Cambridge
£850 to £2,500 for a typical extension or loft in 2026, £500 to £1,000 for single-beam calculations, and £700 to £1,500 for a report on cracking.

How to choose a structural engineer in Cambridge
You need a structural engineer whenever load paths change: removing a wall, forming an opening, adding a loft floor, or building foundations near a neighbour. Building control will ask for their calculations.
- Check for chartered status with the IStructE or ICE.
- Ask whether site inspections and building control queries are included.
- Send the architect's drawings with your enquiry so the quote is for the real job.
- Ask how quickly calculations can be issued, as this often sets the start date.
- Confirm professional indemnity insurance cover.

- What does a structural engineer cost in 2026?
- From about £450 for a single beam calculation to £1,800 for a full extension package.
