AI consultant, agency or freelancer: what each costs a UK business in 2026

In the UK in 2026, freelance automation specialists typically charge £400–£800 a day, mid-tier consultancies £900–£1,600 and boutique specialists £1,200–£2,500. Automation agencies usually price per build instead: roughly £1,000–£25,000 for one process, plus £100–£3,000 a month for support. Which is cheapest depends less on the rate than on whether you already know what to automate.

Disclosure: Lenya is an AI consultancy, so it is one of the options compared here. The figures come from other providers’ published pages, linked at the end, as of October 2026.

The options side by side

Typical UK pricing, as published by providers in 2026
Option	How it is usually priced	Best when	Watch out for
Do it yourself with off-the-shelf tools	Zapier, Make and n8n have free or low-cost plans; entry paid plans are roughly $10–$30 a month	The job is a standard connection between popular apps, and someone on the team has time to build and maintain it	Older software, free-text emails and exceptions; the time it takes your own people
Freelancer	£400–£800 a day; automation work is often billed at £75–£150 an hour	One clearly defined workflow, and you can manage the project yourself	Who maintains it when they move on; documentation and access to accounts
Automation agency	£1,000–£5,000 for a single automation; £4,000–£12,000 for a connected set; £15,000–£50,000+ across several systems; support £100–£3,000 a month	You know which process to automate and want it built and supported	Builds scoped around a tool rather than your process; support costs that grow after launch
AI consultancy (advice, then build)	£900–£2,500 a day for consultancies and specialists, or a fixed price for an assessment followed by priced builds	Work spans several teams and systems, and you want to know where AI pays off before paying for a build	Advice that never turns into anything running; make sure the same firm can build and look after it

Day rates come from Axivon’s 2026 UK pricing article, which cites Helium42; build and support ranges from AI Agency Plus, Crox, Softomate Solutions, Axivon and ExpertSure. Four of these are agencies describing their own market, so treat them as a guide to the range, not a quote.

Why the day rate is the wrong number to compare

A cheaper day rate spent on the wrong process costs more than an expensive day spent finding the right one. For most established businesses, the expensive mistakes are building something nobody uses, automating a process that should have been simplified first, and running an automation that nobody watches once it is live.

Before comparing prices, work out three things:

Do you already know which process to automate, and what it costs you today? If not, you are buying advice first, whoever you hire.
How many systems and teams does the work touch? One inbox and one spreadsheet suits a freelancer or a tool; five teams and an old ERP system do not.
Who will look after it once it is live? Formats change, prices change and exceptions appear. Budget for that from the start.

What a first year typically costs

AI Agency Plus suggests budgeting about £5,000–£8,000 all-in for one workflow in its first year. Crox puts the first year for a typical 10–50 person firm at £10,000–£30,000, with a single well-scoped process at £5,000–£10,000 and multi-system or regulated work at £15,000–£25,000. Ongoing support is the cost buyers most often leave out: published support plans range from about £100 to £3,000 a month.

Questions to ask any provider

Who will actually build it, and who do we call when it breaks?
Will it run inside the systems we already use, or do we log into something new?
Do we own the workflows, prompts and accounts, so we could switch provider later?
How is it monitored once it is live, and what does support cost each month?
Is the price fixed before work starts, and what would change it?
Where is our data processed, and will you sign a data processing agreement?

Where Lenya fits

Lenya is an AI consultancy for established UK businesses. It advises first, learning how the business runs and measuring what each process costs today, then builds AI agents into the systems the team already uses and looks after them once they are live. The price depends on the size of the company and how many teams are involved, and you get a fixed price after a first conversation. See how Lenya pricing works.
