If you’ve never had to hire one before, picking a structural engineer can feel oddly high-stakes. You’re not just choosing someone to do a job, you’re trusting their calculations to hold up a wall, a floor, or your entire extension for decades. Get it wrong and the consequences don’t show up straight away, they show up years later, often when you’re trying to sell the house and a survey flags something.
So it’s worth being a bit more careful here than you might be with, say, choosing a decorator. Here’s what I’d actually check.
Check They’re Properly Qualified, Not Just Confident
Here’s something a lot of people don’t realise: “structural engineer” isn’t a protected title in the UK. Anyone can put it on a business card. What is meaningful is being chartered or incorporated with the Institution of Structural Engineers, or a member of the Institution of Civil Engineers. That’s the bit that actually means someone sat exams, did the training, and answers to a professional body if things go wrong.
It takes about two minutes to search the IStructE or ICE register and check a name. I’d genuinely do this before anything else, even before looking at price.
Ask About Experience With Properties Like Yours, Specifically
Someone brilliant at commercial steel-frame buildings isn’t automatically the right person for your 1890s terrace with a bit of a lean on the back wall. Older homes come with their own problems, foundations that don’t match what’s on any drawing, walls that have been altered without anyone recording it, timber that’s not behaving quite how the textbook says it should.
Just ask them straight: have you done work on houses like mine before? A good engineer won’t mind the question, and their answer usually tells you a lot.
Insurance Isn’t Optional, Even Though It Feels Like Paperwork
This is the one people skip asking about, and it’s arguably the most important. Professional indemnity insurance is what protects you if the calculations turn out to be wrong, and structural mistakes don’t always show up immediately. Sometimes they surface years down the line, sometimes only when a buyer’s surveyor spots something during a sale.
Just ask what level of cover they carry. Anyone properly set up in this line of work will answer without hesitation.
Get the Fee and Scope in Writing, Every Time
Vague quotes cause more grief than almost anything else in this process. Before you agree to anything, get it in writing: does the fee cover calculations only, or drawings as well? Is dealing with building control included, or extra? Will site visits during the build cost more on top?
It doesn’t need to be a long contract. It just needs to exist, so there’s something to point back to if a disagreement comes up later.
Think About Whether They’ll Actually Be Reachable
Builds rarely go exactly to plan. A wall gets opened up and something unexpected turns up, or building control has a query that needs answering before work can continue. When that happens, you want an engineer who picks up the phone or replies within a day or two, not one who goes quiet for a fortnight while your site sits idle and your builder’s costing you for the downtime.
Worth asking upfront how they handle this kind of thing during an active build, not just at the quoting stage when everyone’s naturally more responsive.
Local Knowledge Genuinely Speeds Things Up
An engineer who already knows how your council’s building control department likes things submitted, and roughly how long they take to respond, will often get your project through faster than someone who’s never dealt with that particular authority before. This matters more in areas with a lot of older housing, where local construction quirks come up again and again.
It’s part of why searching for a structural engineer near me tends to work out better than going with a big national firm that’s never set foot in your area.
A Quick Comparison
| What to Check | Why It Matters | How to Verify It |
| Chartered status | Confirms real training and professional accountability | Search the IStructE or ICE register directly |
| Experience with similar properties | Older and unusual buildings behave differently than new-builds | Ask for examples of comparable past work |
| Professional indemnity insurance | Protects you if the calculations are later found to be wrong | Ask directly what level of cover they hold |
| Written scope and fee | Prevents disputes over what’s included later on | Get everything confirmed in writing before work starts |
| Familiarity with your local council | Can speed up building control approval noticeably | Ask if they’ve worked with your specific authority before |
Questions Worth Asking Before You Commit
Are you chartered, and with which body? What’s your insurance cover? Can you point to a similar job you’ve done nearby? What exactly does the quote include? How do you handle questions once building work is actually underway? And roughly how long should the calculations take once you’ve given them everything they need?
Honestly, a decent engineer answers all of this comfortably. If someone’s evasive about insurance or qualifications specifically, that’s the one thing I wouldn’t let slide.
A Few Things That Should Make You Pause
Someone who won’t confirm their chartered status or insurance. A quote with no clear scope attached to it. Calculations that turn up with no drawings or explanation. Not knowing anything about the type of building you actually live in. And generally, anyone unwilling to put agreements in writing, whatever excuse comes with it.
Mistakes People Make When Choosing
Going with the cheapest quote without checking what it actually covers. Assuming a builder’s recommendation is enough on its own, without checking the register yourself. Leaving the insurance question until after the work’s already started. And leaving the whole decision to the last minute, which usually means settling for whoever happens to be free rather than whoever’s actually right for the job.
