There are a lot of firms selling AI to UK construction and very little honest comparison of them. Most of the “best of” lists you will find are affiliate pages, and at least two of the ones ranking today are published by agencies who put themselves on their own list without mentioning it.
So here is the version we wanted to read: who is actually out there, what they are genuinely good at, what they charge where they publish it, and which buyer each one suits. Sourced, dated, and with our own conflict declared.
Taken from each firm’s own published pricing in 27 August 2026. Where a firm does not publish, this says so rather than guessing.
ConstructionX AI
NorfolkAI automation for small construction businesses, founded by a builder.
Where they are strong: Practitioner credibility, and a pricing ladder that lets a small firm start cheaply. Jody Murfit publishes 30 years in construction including 20 as co-founder of a high-end residential builder, and describes himself as "a builder who learned AI" rather than a technologist arriving in construction. The diagnostic fee is credited against any build that follows, which is a fair way to de-risk a first step.
Choose them if: A small builder who wants a low-commitment diagnostic before spending, and who values the adviser having actually run a building firm.

ConTech Consultants
United KingdomAI and automation consulting aimed at construction firms of 20 to 200 staff.
Where they are strong: A clean three-step commercial structure, and an AI readiness assessment as the deliberate first step rather than jumping to a build. They state the aim as helping construction companies "cut costs, win more contracts, and modernise their operations", and they publish every tier.
Choose them if: A mid-size contractor that wants a staged engagement with a written plan before any system is built, and that fits the 20 to 200 employee band they target.

Flowio
Glasgow and EdinburghMulti-sector AI automation agency with a named construction and engineering practice.
Where they are strong: Breadth of integration and the most transparent pricing in this group. They publish a stack covering n8n, Zapier, Make, OpenAI, Claude, Gemini, Salesforce, HubSpot, Xero, QuickBooks, Microsoft 365, Google Workspace, WhatsApp and Slack, and they quote figures rather than ranges: "automation packages start from £750 for a single workflow automation".
Choose them if: A firm that wants one clearly scoped workflow automated quickly and cheaply, or that needs an unusual integration with an existing tool. Also the strongest option here if you are in Scotland and want someone local.
Published stack: n8n, Zapier, Make, OpenAI, Claude, Gemini, Salesforce, HubSpot, Xero, QuickBooks, Microsoft 365, Google Workspace, WhatsApp, Slack.

Aucta AI
Dover, KentAI systems partner working across sectors, with published construction workflows.
Where they are strong: A refreshingly concrete promise: "Not a deck. Not advice. A working system", delivered in fixed two to four week sprints at a fixed price. Their published construction work covers tender tracking and response, subcontractor communication and document routing, and they are strong on the front of the funnel with voice agents and lead qualification.
Choose them if: A contractor whose pain is commercial rather than operational: missed enquiries, slow quotes, tender response capacity. Their lead-response focus is a genuinely different emphasis to ours.

AI Metric (this is us)
Liverpool, EnglandConstruction-native AI consultancy for UK contractors and consultants.
Where we are strong: Depth in the contractual record rather than the front of the funnel. Twenty years in Tier 1 delivery behind the positioning, work anchored in JCT and NEC vocabulary, Building Safety Act golden thread evidence and ISO 19650 file naming, and a WhatsApp site assistant that builds the daily record from what crews already send rather than asking them to adopt an app.
Choose us if: A contractor whose problem is the record: site reporting, document production, evidence that has to survive a valuation, a delay claim or a gateway review. If your problem is missed calls and slow quotes, one of the others above is a better first call and we will say so.
Our pricing: Not published for consultancy engagements, which is a fair criticism of us on a page about transparency. The Construction Metric product is published at £199 per site per month with unlimited users.
Check us the same way: the twenty years, what we actually do, and the £199 published in full.
Work out which of these three sentences is most true of your business, because it decides the category before it decides the firm.
Who should a UK contractor hire to automate their admin with AI?
It depends which problem is costing you most. If enquiries go unanswered and quotes are slow, a firm strong on lead response and voice agents will pay back fastest. If your problem is the record, meaning site reporting, document production and evidence that has to survive a valuation or a claim, you want someone fluent in JCT, NEC and the Building Safety Act. If you want one specific workflow automated cheaply, a general automation agency with published per-workflow pricing is the efficient answer. The category matters more than the brand.
What does AI automation cost for a UK construction SME?
Published UK prices as at August 2026 run roughly like this. A diagnostic or readiness assessment costs £497 to £750. An implementation costs £2,500 to £3,000 to begin, with complete builds commonly quoted between £1,500 and £15,000 depending on scope. Ongoing support runs £150 to £1,500 a month. Several firms publish nothing and quote only after a call.
Why is AI Metric in its own comparison?
Because leaving ourselves out would be more misleading than including ourselves and saying so. We have stated the conflict at the top of the page, sourced every claim about every firm to their own public material, and named the buyers we are the wrong choice for. Where a rival fits better we say which one and why.
Should I use a construction specialist or a general AI agency?
A generalist with strong integration skills is often better value for a single well-defined workflow, and several publish lower entry prices for exactly that. A construction specialist earns its premium when the output has to be defensible to someone who is not on your side: a client quantity surveyor, an adjudicator, a Building Safety Regulator gateway reviewer. Ask any firm how they would handle a specific contractual document from your own business, and judge the answer.
