Common questions

Everything you need to know.

Answers to the questions our clients ask most often.

How much does a structural engineer cost in the UK?

Typical costs range from £400–600 for a site survey, £800–1,500 for structural drawings, and £1,500–3,500 for a full package.

Do I need a structural engineer for a loft conversion?

Yes — almost always. Building control requires structural calculations and drawings for any loft conversion involving changes to the roof structure or floor loading.

How long does a structural engineer report take?

A site survey report is typically delivered within 3–7 working days. Structural drawings and calculations usually take 1–3 weeks depending on project complexity.

Is it free to get a quote through your platform?

Yes — completely free for homeowners and developers. We charge a small introduction fee to the engineer only when a project is awarded through the platform.

Loft Conversion · Camden

“We started with a blank sheet of paper, knowing we wanted more kitchen and living space. We ended up with something we hadn’t even considered at the start. SENM took us through a number of iterations, helping us move past our original, quite closed vision and look at what was really possible.”

Rear Extension · Kingston upon Thames

“We still have those pinch-me moments where we look around and think, ‘Really? Wow. This is ours.’ Every detail has been so thoughtfully designed, and the space has completely transformed the way we live and entertain. It’s beautiful, practical, and feels like home.”

Load-bearing Wall · Greenwich

“SENM helped us create the perfect party house while retaining the modern character of our home. The design gives us generous, open spaces for entertaining without compromising on how the house works day to day. The team understood our vision and turned it into a home that feels both stylish and genuinely enjoyable to live in.”
