What construction project management software actually costs in the UK
Expect roughly £20 to £60 per user per month for tools that charge per seat, £100 to £300 a month flat for small-firm tools that don't, and a quote you have to ask for at the enterprise end. The number that catches people out isn't the headline price. It's the per-user multiplier once the site team and the office are both on it, and the cost of the decision nobody can prove was made.
What are the actual price ranges?
Broadly three bands. Per-seat field tools sit around £20 to £60 per user per month depending on tier and whether you pay annually. Flat-rate tools aimed at small and medium firms tend to run somewhere between £100 and £300 a month for the whole business. Enterprise platforms don't publish a number at all and price on project volume, headcount and which modules you take.
Treat every figure here as a starting point rather than a quote, including ours. Pricing in this category moved noticeably during 2026, and the only number that binds anyone is the one on your own invoice. Check current pricing before you budget, and check what the price includes: the people you employ, or everyone on the job.
The band you land in says more about which half of the job you are buying software for than about the size of your firm. Estimating, costing and scheduling tools sit in the expensive bands because they replace a person's work. Tools for the other half, the documents, the photos, the decisions you need from clients and subcontractors, sit lower, because what they replace is your evenings.
Why do so many vendors hide their pricing?
Because a sales conversation converts better than a pricing page when the number is large. If the answer would make a small firm close the tab, moving to "request a quote" keeps them on the phone long enough to hear the value first. That's a rational choice for the vendor and an expensive one for you, because it costs you a call and a follow-up sequence just to find out whether you are in the right ballpark.
The trend went the wrong way recently. Tools that used to publish a plan table have moved to custom quotes, which makes like-for-like comparison genuinely harder than it was two years ago. If you're shortlisting, ask for the number in the first email and treat reluctance to give one as information.
A published price also tells you who the tool is for. A vendor that prints £29 a month expects a two-van firm to buy it from the page without a call. A vendor that prints nothing expects a procurement process, a demo and a contract, and a firm without those things isn't the customer it wants.
What does per-user pricing really cost a small firm?
Take a firm with four in the office, six on site and a handful of regular subcontractors. At £35 per user per month that is £350 a month before anyone outside the business is involved, and £4,200 a year. Add the subcontractors and it climbs again.
The real cost isn't the invoice, though. It's what the invoice does to your behaviour. Per-seat pricing quietly encourages you to leave people off, and the person left off is always the one whose yes you needed: the client, the architect, the subbie who only has to look at a drawing twice a week. They never get a seat, so their approval never happens in the system. It happens in an email, a text or a phone call, and that's where it stays when the argument starts.
Ask the questions that expose this before you compare headline prices.
- Do clients, architects and subcontractors count as billable users?
- Can someone approve a drawing without being a user at all?
- What happens to your bill when someone leaves mid-month?
- What's the price at renewal, not just in year one?
What is the cost that never appears on the invoice?
Every job has the moment where the client says "I never agreed to that". The variation you priced, the extra day the subcontractor claimed, the finish the architect chose and then forgot. If the agreement lives in a WhatsApp thread, a phone call or a nod on site, the argument is decided by whoever remembers it most confidently, and the money goes to whoever wrote the better email afterwards.
That cost dwarfs any subscription. A single unpaid variation is worth more than a year of most of the tools on this page, and the rework that follows a decision nobody recorded costs more again. No pricing page puts it on the comparison table, because the tools that charge per seat can't fix it: the person who needs to say yes is precisely the person who won't create an account.
So the question to ask of any tool isn't only what it costs a month. It's whether, when the client, the architect or the subcontractor says yes, you end up holding something you could put in front of an adjudicator: dated, signed, and pinned to the exact drawing or quote they saw.
What does Portal Worx cost?
Plans start at £29 a month, with 20 per cent off if you pay annually, and the prices are published on the pricing page rather than behind a call. The trial is 14 days on the Professional plan with no card required.
There is no second meter. Every plan includes unlimited users and unlimited sign-off requests and share links, so your office, your site team, your clients and your suppliers cost the same as one person, and the people you send a link to need no account at all. What the plans are cut on is the size of the workspace behind the record: live projects, storage and AI credits. Your own logo and colour go on the pages your clients open on every plan, including the cheapest one.
What you get for that is the thing the per-seat tools can't sell. You upload the drawing, the quote or the variation, send one person a link, and they open it on their phone with nothing to install. They can leave a note, ask a question, approve or decline, and sign with a finger. The record comes back dated, signed and pinned to the exact file they saw, with its SHA-256 fingerprint, and it stays on the job next to the photos that justify it.
Where is Portal Worx not the right fit?
If your problem is pricing work and tracking cost against budget, this is the wrong tool and a cheap answer to the wrong question. There's no estimating, no takeoff, no job costing, no invoicing, no scheduling or Gantt, no timesheets and no task lists. Buying it expecting those would be a waste of your money and our time.
It covers the other half of the job: the decisions you need from people outside your business, and the workspace that keeps the signed record beside the documents, the site photos, the reports and the conversations it belongs to. Plenty of firms run it alongside their accounting or estimating package rather than instead of one.
One more honest limit. The sign-off proves that whoever signed had control of the email address you sent the link to, when you ask for the one-time code. It isn't an identity check. A deed or a property transfer needs a notary, not us.
Common questions
- Is construction software usually priced per user?
- It varies. Field-focused tools tend to charge per user per month, while several small-firm tools charge a flat rate for the whole business. The distinction matters most if you need clients, architects and subcontractors to say yes to things, because a per-seat tool gives them no seat and their approval stays in email.
- Why won't some vendors publish a price?
- Because a sales call converts better than a pricing page when the figure is large. Several tools that used to publish plan tables moved to custom quotes, which makes direct comparison harder than it used to be. Ask for the number in the first email.
- Do clients and suppliers count as paid users?
- On Portal Worx, no. Every plan includes unlimited users, and the people you send a sign-off link to need no account at all. On per-seat tools this varies, so ask directly before you compare headline prices.
- What's the cheapest way to start?
- Portal Worx plans start at £29 a month, with 20 per cent off annually, and every plan includes unlimited users and unlimited sign-off requests. The 14-day trial runs on the Professional plan and needs no card.
- Does Portal Worx handle estimating or job costing?
- No. There's no estimating, takeoff, job costing, invoicing, scheduling or timesheets. It covers sign-off from people outside your business and the workspace that keeps the record: documents, site photos, reports, messaging and the activity trail.
