You've decided to stop pricing everything yourself, or you've got more tenders coming in than your own estimator can handle. So you search for construction estimating companies UK and get a page of firms that all say roughly the same thing: accurate, fast, affordable, experienced. None of that helps you choose. What helps is knowing which questions to ask, and what a good answer sounds like.
This is the checklist we'd use on your side of the desk. We're one of the firms you might be comparing, so judge us by the same list.
Start with how they measure
Every estimate is quantities multiplied by rates. If the quantities are wrong, nothing else on the page matters.
Do they measure to NRM2?
NRM2 is the RICS standard for the detailed measurement of building works. An estimating company working to it describes and measures each item consistently, so the quantities mean the same thing to you, your client and any QS who picks them up later. If a firm can't tell you what method it measures to, that's an answer in itself.
Will they show you the measurements?
This is the big one. A total on a PDF isn't an estimate you can use. You need to see the quantity behind each line, and ideally where on the drawings it came from, so you can check the parts you know best. If you're only ever given element totals, you're being asked to trust the number rather than check it. There's more on this in our piece on transparent pricing and why every rate in a tender has to add up.
Rates that match where the job is
Rates are the other half of the sum. Ask where they come from and when they were last updated. An old rate book, or rates built for a different country's market, will produce a tidy estimate that's wrong in ways you can't see from the page.
Labour and materials don't cost the same across the UK either. A job in central London and one in rural mid Wales shouldn't be priced off the same labour rates, and haulage to a remote site isn't the same as a delivery round the corner from the merchant. Ask whether the company adjusts for location, and how. Our piece on construction estimating priced to local UK rates goes into why that matters on real jobs.
Fees, sample output and being able to ask questions
Is the fee fixed before they start?
You should know what the estimate will cost before any work is done. Open-ended hourly billing makes it hard to decide whether a tender is worth pricing at all. A fixed fee, agreed from the drawings up front, lets you make that call with the full picture.
Can you see real sample output?
Any serious estimating company should be able to show you what you'd actually receive: the layout, the level of detail, how quantities and rates are set out. Look at it the way you'd look at your own tender. Could you submit from it? Could you defend a line if the client queried it? Our sample estimate is open to view without handing over an email address, and that's a fair standard to hold any firm to, us included.
Can you query a line and get a straight answer?
Estimates get questioned. By you, by your client, by their QS. Ask what happens when you come back with "why is this quantity what it is?" You want someone who can answer from the take-off itself, not a generic reply a few days later. The ability to query individual lines is often what separates an estimate you can work with from one you just have to accept.
Who actually does the work
This question gets skipped more than any other. The person you speak to isn't always the person who measures your drawings. Some firms pass work to freelance estimators. Some have the measuring done overseas and checked (or not) in the UK.
Offshore estimating isn't automatically poor, and there are capable measurers all over the world. But pricing UK work well takes more than measuring skill. It needs familiarity with UK construction methods, UK Building Regulations, how UK specifications are written, and what labour and materials actually cost here now. A firm quoting UK work should be open about where the work is done and how UK rates are applied to it. If the answer is vague, ask again.
So ask directly:
- Who will measure my drawings, and where are they based?
- Who checks the estimate before it comes back to me?
- If I have a question, who do I speak to, and will they know the job?
- If the drawings are revised, does the same person update the price?
The same questions apply if you're weighing up an individual rather than a company. We've compared the two in freelance construction estimator or an estimating service, and neither route suits everyone.
A checklist for comparing construction estimating companies UK
Search results for construction estimating companies UK rarely tell you how a firm actually works, so put these to each one before you send any drawings:
- Measures to NRM2, and says so plainly
- Shows the quantities behind every line, not just totals
- Prices on current UK rates, adjusted for the job's location
- Agrees a fixed fee before starting
- Has sample output you can look through properly
- Tells you who does the work and where they are
- Lets you query any line and gets back to you with a real answer
- Works to your tender deadline, not a day after it
For what it's worth, this is how we work at MPE. We measure every element off your drawings to NRM2, price it on current UK rates local to the job, agree a fixed fee before we start and deliver to your tender deadline, anywhere in the UK. You can read more about our construction estimating services UK contractors use, but run us through the same checklist as everyone else.
Whichever firm you pick, pick the one whose estimate you'd be comfortable defending line by line.
