Once you’ve got a few names on a shortlist, the tricky part isn’t finding structural engineers, it’s telling them apart. Every quote looks roughly the same at first glance. A fee. A rough timeline. A promise of calculations. The stuff that actually matters is usually underneath that, and it’s worth digging for before you sign anything.
Don’t Start With Price
I know it’s tempting to just line up three numbers and pick the middle one. But the first thing worth checking is whether each person is actually chartered, either with the Institution of Structural Engineers or the Institution of Civil Engineers. Nobody’s stopping someone from calling themselves a structural engineer without either, the title isn’t protected. So this check does more work than almost anything else on the list.
Takes two minutes on the register. If a name doesn’t come up, it’s not automatically a red flag, some people work under different arrangements, but it’s a fair question to ask them directly.
Compare What’s Actually Included, Not Just the Number
This trips people up constantly. One quote looks cheaper purely because it covers less. Does it include drawings, or just calculations? Is building control liaison part of the deal or billed on top? What about site visits once the build’s actually underway?
Ask each engineer to break it down properly. Once everyone’s quoting against the same scope, the numbers usually make a lot more sense, and sometimes the pricier-looking one turns out to be the better deal once you see what’s actually in it.
Experience With Your Type of Property Matters More Than Years in the Job
Someone with two decades in commercial steel-frame buildings isn’t necessarily better placed for your Edwardian semi than someone five years into domestic work specifically. What matters is whether they’ve dealt with something like your job before, similar age of house, similar alteration, similar construction.
Just ask for an example or two. You’re not after a full portfolio, just enough to know they’ve seen this particular headache before.
Insurance, Before Anything Else Technical
Professional indemnity cover protects you if the calculations turn out wrong later, and structural problems don’t always show up straight away. Sometimes it’s years down the line, often when a buyer’s surveyor spots something during a sale.
It’s a plain question: what level of cover do you hold? Anyone properly set up answers this immediately, no hedging.
How They Communicate Now Tells You Something
Notice how someone responds at the quoting stage. Fast reply? Actual answers to your actual questions, or something generic that could apply to any house? Did the quote read like it was written for your property specifically, or copied from a template?
Not scientific, but it’s rarely misleading either.
Comparing Your Shortlist
| What to Compare | Why It Matters | How to Check It |
| Chartered status | Confirms real training and accountability | Search the IStructE or ICE register |
| What’s included in the quote | Stops you comparing a cheap-but-incomplete quote to a full one | Ask for a proper breakdown |
| Relevant experience | Older and unusual buildings behave differently than new-builds | Ask for examples of comparable projects |
| Insurance level | Covers you if calculations are later found to be wrong | Ask directly what cover they carry |
| How they’ve communicated so far | Fairly reliable preview of how responsive they’ll be mid-build | Notice speed and quality of their replies |
Questions Worth Asking Every Engineer on Your List
Are you chartered, and where? What’s actually in this quote, and what costs extra? Have you done work on properties like mine before? What insurance do you hold? How do you handle questions once the build’s underway? Roughly how long for calculations once you’ve given them what they need?
Ask everyone the same questions. It makes the differences obvious fast, usually within one or two replies.
When to Walk Away From a Quote
No clear scope attached to the fee. Won’t confirm insurance or chartered status when you ask directly. A quote that clearly wasn’t tailored to your actual property. Nothing said about building control. General reluctance to put anything down in writing.
Mistakes People Make Comparing Quotes
Picking the lowest number without checking what it covers. Not asking every candidate the same questions, which makes comparing them properly almost impossible. Assuming whoever replied fastest is automatically the best option. Rushing because a builder’s chasing a start date, which usually ends with whoever happened to be free rather than whoever was actually right for the job.
The Short Version
Ask the same questions of everyone. Check chartered status before you look at price. Make sure you’re comparing quotes with matching scope, not just matching totals. Takes a bit longer upfront, saves a lot more further down the line.
If you’re still narrowing things down, searching for Structural engineers near me and cross-checking each name against the professional register is a decent way to start.
