Do I need a structural engineer?

Here are just some of the reasons why you may benefit from our services

When do I need a structural engineer consultant?

As a general rule, any work that changes the structure of a property requires planning permission or Building Control approval. And to get that you’ll need to supply technical information from a structural engineer.

If the work means no additional loads are being added to the structure of your building, it’s unlikely you’ll need one. However, we recommend you always check whether you need a structural engineer for a project. Your architect or building contractor will be able to advise you on this.

The types of work that regularly require a structural engineer can include:

  • House renovations that change the structure of the property
  • Building an extension
  • Modifying doors and windows
  • Fitting solar panels
  • Loft conversions
  • Removing or modifying internal walls
  • Underpinning floors
  • Removing chimney breasts
  • Adding new structural elements such as roofs, floors or foundations

This isn’t an exhaustive list. There may be other occasions where you will need the advice of a local structural engineer. Check with your architect or builder.

What is a structural engineer and what do they do?

Structural engineers specialise in the structure of buildings and are able to determine their strength, durability and safety. Through calculations and drawings, they are able to ensure the structure of a building will withstand the forces applied to it.

Architects provide the design, but not the structural calculations of a project. That’s where the structural engineer comes in. Their precise work complements the architect’s and makes sure the structure will stand safely once the job is completed.

Inspections on a property

A structural engineer consultant can also provide advice on a property you want to buy, or on your existing property if it’s showing signs of subsidence or other structural issues.

As an expert witness

If you’re in a disagreement with someone regarding a structural matter on your property, a structural engineer can inspect the site and produce an unbiased report which includes advice on potential solutions.
