7 questions to ask a structural engineer for a quote
TL;DR: Before hiring a structural engineer, ask about their qualifications, experience with your project type, fees structure, timescales, site visit arrangements, insurance coverage, and references. These seven questions help you compare quotes fairly and find the right professional for your building work.
Introduction
Getting a quote from a structural engineer is a crucial step before starting any building project. Whether you’re extending your home, converting a loft, or repairing a damaged wall, you need the right expert on board. Structural engineers assess your building’s integrity and design safe solutions. But not all quotes are created equal. Asking the right questions helps you understand what you’re paying for and ensures you hire someone qualified. Let’s explore the seven essential questions to ask when getting a structural engineer quote.
What Qualifications and Accreditations Do You Hold?
This is your starting point. You want someone with proper credentials. Look for chartered engineers with “CEng” after their name. They should be registered with the Institution of Structural Engineers or a similar body. Ask if they’re insured and registered with the appropriate professional body. This protects you if something goes wrong.
Reputable engineers won’t mind sharing their qualifications. It’s standard professional practice. Proper accreditation means they’ve met strict training requirements and follow codes of conduct.
How Much Experience Do You Have with My Type of Project?
Different projects require different expertise. Loft conversions aren’t the same as basement excavations. Ask specifically about their experience with your project type. How many similar jobs have they completed? What was the outcome?
An engineer experienced in your specific work will give better advice and faster results. They’ll have encountered problems you might face. They know what solutions work best. Don’t just accept general experience. You want someone who’s done exactly what you need done.
What’s Your Fee Structure and Will You Provide a Detailed Quote?
Never accept vague pricing. Ask how they charge: hourly rates, fixed fees, or percentage of construction costs? UK structural engineers typically charge between £1,500 and £5,000 for residential projects, depending on complexity.
Request a itemised quote showing exactly what’s included. Does it cover site visits, drawings, calculations, and follow-up inspections? Are there additional costs if you need revisions? Hidden charges crop up later if you don’t clarify now. A good quote lists everything separately.
How Long Will the Project Take from Start to Finish?
Timescales matter for your plans. Ask how long they need for the survey, producing drawings, and providing follow-up support. Most straightforward residential jobs take two to four weeks. Complex projects take longer.
Ask when they can start too. Some engineers have long waiting lists. Check if delays affect your building timeline. Understanding the full schedule helps you plan other tradespeople and avoid bottlenecks on site.
Will You Conduct a Full Site Visit Before Providing Your Quote?
A proper assessment requires visiting your property. They need to see the existing structure, soil conditions, and any problems firsthand. Never trust a quote from someone who hasn’t visited your site.
During the visit, they’ll take measurements, photos, and notes. They’ll identify potential issues. This thorough approach means their quote and advice are accurate and tailored to your home, not generic.
What Insurance and Guarantees Do You Offer?
Professional indemnity insurance protects you if something goes wrong. Ask for proof of current cover. Most engineers carry at least £1 million cover. This isn’t optional. It’s essential protection.
Ask what happens if you need them to revisit or revise their work. Do they offer any guarantee or warranty on their designs? What support do they provide during construction? Clear answers reassure you they stand behind their work.
Can You Provide References from Recent Clients?
References reveal real-world experience. Ask for contact details of recent clients who’ve completed similar projects. Call them and ask directly: Were they happy? Did the work go smoothly? Did it stay within budget?
Speaking to actual clients gives you honest insights you won’t get elsewhere. It’s the quickest way to spot red flags or confirm you’ve found someone reliable and professional.
Conclusion

You’ll understand what each engineer offers, what you’re paying for, and whether they’re right for your project. Don’t rush this process.
