Questions to ask your structural engineer before hiring
TL;DR: Before hiring a structural engineer, ask about their qualifications, experience with your project type, insurance coverage, timeline, costs, and references. Clear communication helps you understand their process and ensures you’re getting professional expertise for your building needs.
Introduction
Hiring a structural engineer is a big decision. You’re trusting them with your home or business safety. Whether you’re dealing with subsidence, planning an extension, or need building regulations approval, asking the right questions upfront saves time and money.
A good structural engineer will welcome your questions. They’ll explain things clearly and help you feel confident about your project. We’ll walk through the essential questions to ask before you sign anything or hand over payment. This guide helps you find the right professional for your needs.
What qualifications and certifications should they have?
Your engineer should be chartered. Look for letters like “CEng” or “IEng” after their name. These show they’re registered with the Engineering Council. They should also have professional insurance through organisations like the RIBA or ICE.
Ask to see proof of their qualifications and current insurance certificates. Don’t be shy about this. Chartered status matters because it means they’ve met strict standards and can be held accountable. They should belong to a professional body. This protects you if something goes wrong. Most reputable engineers are happy to share these details.
How much experience do they have with your specific project?
Tell them exactly what you’re planning. An extension? Subsidence repairs? Underpinning? Ask how many similar projects they’ve completed. Get specific numbers and details about their experience.
Experience matters hugely. An engineer who’s fixed dozens of subsidence cases knows the pitfalls. Someone new to your project type might miss important details. Ask for examples of similar work. Request case studies or photos if possible. How long have they been practising structural engineering? Years count here.
What’s included in their quote and timeline?
Get everything in writing. Ask what the fee covers. Will they do site visits? How many? Will they produce drawings? What about building regulations applications? Are there extra charges for revisions?
Understand their fee structure completely. Some charge hourly rates (typically £100 to £250 per hour). Others quote fixed fees for specific projects. Ask about payment terms. Do they want a deposit? When’s the balance due? Get a realistic timeline. How long until they can visit? How long for the report? For drawings? When can work start on site?
Do they have professional insurance and references?
Ask about their professional indemnity insurance. This covers mistakes or omissions. The minimum recommended cover is £1 million. Request references from recent clients. Ring them up. Ask about their experience working with this engineer.
Were they happy with the service? Did the engineer communicate well? Were there any surprises? Did the project stay on budget and timeline? Client references tell you how they actually work, not just what they promise. A reputable engineer will happily provide contact details of satisfied clients.
What’s their communication style and availability?
You want someone who’s easy to contact. Ask how often they’ll update you. Do they prefer email, phone, or site visits? What’s their response time for questions? Are they available if you need urgent clarification?
Clear communication prevents problems. You shouldn’t feel ignored or confused about what’s happening. A good structural engineer explains technical stuff in plain language. They answer your questions patiently. They’re responsive to your concerns. Check if they’re available for the whole project duration, not just the initial report.
Conclusion
Asking these questions before you hire shows you’re serious. You’re protecting your investment and your property. A professional structural engineer expects these questions and will answer honestly. They’ll provide qualifications, insurance details, references, and clear pricing. Take time to compare options. Get multiple quotes if you’re unsure.
