AI automation agency UK prices: what one workflow costs to build and run

What does one automated workflow cost, from web enquiry to chased quote?

UK firms publish anything from £750 to £30,000 to build one workflow; two guides, AI Agency Plus and Softomate, put it at £1,500 to £5,000. Our published prices for a single workflow run from £195 to £695. We're Logica HQ, a UK AI engineering firm that sells AI automation, and we wrote this guide. Here's the build and message cost for one example job.

1. The job

   A firm gets 60 web enquiries a month and sends 40 quotes. Each enquiry needs an instant reply, and each quote needs chasing until the customer answers. Both are already done by hand, just not reliably.

2. Build, bought separately

   Speed-to-lead from £495 plus quote follow-up from £695 comes to from £1,190.

3. Build, as a bundle

   Our lead system bundle is from £795. It includes those two plus missed-call text-back and review requests, which would come to from £1,680 bought separately.

4. Messages each month

   60 enquiry replies plus 40 quotes × 3 chasers is 180 texts. At cost, about 3p to 4p each, that's £5.40 to £7.20 a month. It's a high case, because the chase stops when someone replies.

Monthly support is separate and optional, with no minimum term. Our pricing page lists support and optimisation at £495 a month, covering monitoring, fixes and improvements across everything we built. AI usage is charged at cost on top. Ask everyone else for their support figure before you agree anything.

If you want to fix the chasing by hand first, our guide on following up a quote has the wording and the timing.

What does each automated workflow cost to build?

Each automated workflow we build has its own fixed starting price, from £195 for review requests to £695 for quote follow-up or invoice chasing. "From" means more scope can raise it, and the price is agreed before work starts.

Our reminders line is priced on a connection to your booking system, so ask its vendor whether it offers an API or a calendar sync before you rely on it.

What do other UK firms publish for one workflow?

Other UK firms publish between £750 (flowio) and £30,000 (Cloudswitched) for one workflow, and most of those figures are bands rather than prices. They come from each firm's own page, listed alphabetically and checked on 6 November 2026.

Why can one workflow be quoted at £695 or £8,000?

Quotes for one workflow differ with what's connected, how much judgement it needs and what's included. crox and AI Agency Plus both say price follows how many systems are connected, and Rocking Tech lists what its price includes. If you've got two quotes that don't look comparable, these are the things to check.

• Systems touched

  Sending a chaser from a spreadsheet is a smaller build than reading and writing to your job software. Each extra system adds work and something else that can break.

• Rules or judgement

  A fixed rule ("no reply after three days, send this") is cheap. Reading a customer's email and deciding what it means needs an AI model, more testing and a person to check it.

• Clean data

  Automation runs on what your records say. Softomate says data quality problems can add £800 to £2,500, so ask whether a quote assumes tidy records.

• What's included

  Some prices include documentation and training, as Rocking Tech's does. Others are the build alone. Ask for a list, not just a figure.

• Whether it counts as marketing

  The ICO treats messages that "confirm or remind them about appointments" as service messages, but promotional content makes a message direct marketing. A reminder is simple. A campaign to past customers needs more care, and more of your time.

What does AI automation cost to run each month?

AI automation costs from about £40 to £400 a month for running costs (AI Agency Plus), and £200 to £800 where a maintenance retainer is counted (Softomate), with crox quoting retainers up to a few thousand pounds. The spread comes from what each one counts. Softomate's price list also warns that "monthly plans, required third-party services and usage must also be budgeted".

• The automation tool

  A monthly subscription or a small server, which some builders include in their own fee and others leave you to pay directly.

• AI model usage

  Charged by how much text it reads and writes. Our AI agent cost guide works through that sum, so we won't repeat it here.

• Messages and calls

  Texts, WhatsApp messages and call minutes, usually charged per use. We pass these on at cost with no markup.

• Someone keeping it working

  Monitoring and fixes when a connected system changes. On Softomate's breakdown this retainer is the largest line, so it's the one to ask about first.

Voice costs more to run than text, because calls are billed by the minute. Our AI receptionist is £695 to set up and £149 a month with 500 call minutes included, and any beyond that are at cost. The AI receptionist cost guide compares it with the alternatives.

Do you need an automation or an AI agent?

You need an automation if the steps are the same each time, and an AI agent only if the work needs reading and deciding across more than one case. Chasing an overdue invoice is an automation. Reading supplier invoices of every layout and posting them to your accounts is closer to an agent, and our document extraction starts from £1,450. Our guide to AI agent costs has the tiers and other firms' prices for that kind of build.

Can you build a workflow yourself with an off-the-shelf tool?

You can build a simple workflow yourself if it follows fixed rules and someone in the firm is patient with software. AI Agency Plus puts a do-it-yourself first year at £100 to £1,000 and says it suits work that's "simple, rule-based", with someone technical to run it. The bill is low because your own time isn't on it. Budget for the hours spent building, and for whoever fixes it when it stops working on a busy day.

Passing data from one tool to another in a straight line is a fair first project. Once it has to read messy emails, touch several systems or keep running while nobody's watching, paying for a build starts to make sense. That's the work our custom AI agents are built for, from £1,450.

Which five questions should you ask an AI automation agency?

• What will this one workflow cost in the first year, with build, support, tools, messages and AI usage added up?
• Which systems does that price assume it connects to, and what if one has no way in?
• Is support optional, and what stops working if I cancel it?
• Who owns the accounts and the build if I leave?
• Does the price include VAT, and what's the refund if it doesn't do what we agreed?

Is it worth automating? Do the sum first

Automating a workflow is worth it when the hours it saves are worth more than it costs, and low-volume work often fails that test. AI Agency Plus says anything under a couple of hours a week "rarely clears a four-figure build inside a year". crox works through five hours a week at £20 an hour, about £5,200 a year.

Hold off if the process changes every few months or lives in one person's head, and fix messy records before paying anyone. AI Agency Plus gives the same advice. A clear process with steady volume is the one to automate first.
