What Does Business Process Automation Cost in the UK in 2026?
Ask what business process automation costs and you will get answers from £10 a month to six figures - all technically true. The honest answer depends on who does the work: you, a contractor, or a managed service. This guide lays out the real UK ranges for 2026, including the costs that never appear on pricing pages, so you can compare like with like.
Route One: DIY Platforms
Zapier, Make, n8n, Power Automate: roughly £10-£150 a month in subscriptions depending on volume and seats, plus AI model usage if your workflows call one. The visible cost is trivial; the invisible cost is the build and the ownership - realistically 5-10 hours a month of someone's time to maintain a handful of business-critical workflows, plus the risk that lives in one person's head. Priced at what a founder's or manager's hour is actually worth, DIY is rarely the cheap option it appears; it is the right option when you have technical staff with genuine slack.
Route Two: Contractors and Consultancies
UK automation contractors typically charge £400-£800 a day; specialist consultancies £800-£1,500. A meaningful automation project - discovery, three to five workflows, testing, handover - lands anywhere from £5,000 to £40,000 depending on complexity and who you hire. The structural catch is what happens after handover: the workflows are yours, which sounds good until they break at month four and the contractor is on another engagement. Budget for a support retainer or an internal owner, or the project quietly decays.
Route Three: Managed Services
Done-for-you providers bundle the build and the running: engineers scope and build the workflows, then operate them - monitoring, fixes, and changes included - for a setup fee plus a monthly fee. UK pricing for services of this shape typically runs £2,000-£12,000 for setup and £1,000-£3,500 a month. It is the most expensive route on paper and often the cheapest per working workflow, because the failure mode of the other two routes - built, then abandoned - is priced out. The right test of any quote is not the fee; it is whether the provider will put the expected return in writing next to it.
The costs pricing pages leave out, whichever route you take:
- Your time in discovery - nobody can automate a process you cannot describe
- Maintenance when a connected app changes its interface or auth
- Monitoring - who notices when a workflow silently stops?
- AI model usage, which scales with volume on every route
- The cost of a workflow that sends something wrong: reputation, not software
Compare routes on cost per working workflow per year, not on the subscription line. A £50-a-month platform nobody maintains costs infinitely more per working workflow than a managed service that runs.
Whatever route fits, insist on the same discipline: a written baseline of the hours a process currently eats, a written estimate of what automation returns, and a review against both after ninety days. Any provider - or internal champion - unwilling to be measured that way is telling you something useful about the likely outcome.
