How do you choose an AI automation agency in the UK?
Choose on process and evidence. Look for an agreed success metric, a fixed price up front, a build on your accounts and a clear maintenance plan. Typical UK builds start in the low thousands (illustrative ranges below), with the exact figure confirmed in a written scope before work begins.
That's the short version. Strong projects begin with an agreed definition of success and a number everyone can check. Here's what the work should cost, the ten questions to ask, and the evidence to expect.
One thing to know before you read on: we're an automation agency, so we're one of the options you'd be choosing between. We've written this to be useful whichever route you choose, including a section on where our model fits best.
What should an AI automation agency cost in 2026?
The ranges below are illustrative UK market figures for 2026: what agencies across the market typically charge, not our rate card. The agency should turn these into a fixed quote for your specific scope before you commit.
| Engagement | Illustrative UK market range | What you should get |
|---|
| Discovery / audit / paid pilot | £500 – £2,500 | Your processes mapped, a prioritised plan, sometimes a small working proof |
| Single-process build | £2,000 – £10,000 | One live, tested workflow with a fixed scope, such as invoice chasing or lead follow-up |
| Multi-system or AI-heavy build | £10,000 – £30,000+ | Several tools connected, custom logic, AI steps with human sign-off |
| Ongoing retainer | £500 – £3,000+ per month | Monitoring, fixes when apps change, and a pipeline of new automations |
The biggest driver of where you land in a range is integration complexity: how many tools are being connected and how well they play together. We've broken that down in AI automation costs in 2026.
We quote every build as a fixed scope after a free audit, so you see the price before anything gets built.
The ten questions to ask any agency (including us)
- "What will success look like, and can we agree it as a number before you build?" The single most important question. A strong agency can name the result and show how it will be measured.
- "Is the quote fixed, and do I see it before work starts?" Look for a fixed scope agreed in writing before you commit, with the assumptions that shape the price listed beside it.
- "Who owns what you build: the accounts, the workflows, the data?" Ownership should stay with you. The build should run on your accounts with your logins, so the complete system stays with you.
- "How are connected apps monitored and updated?" Ask who monitors the runs, how updates are handled and what that support costs.
- "Do you train AI models on my data?" AI training should be disabled. Ask how your data is stored, who can access it, and how they handle UK GDPR.
- "How will you confirm my current tools connect?" The agency should confirm your stack and list each connection in the plan before you sign.
- "Who looks after it after launch, and what does that cost?" The build price and the running cost are different numbers. Get both up front.
- "Can you walk me through your process, step by step?" A named process shows how the project will be managed. Ours is Audit → Plan → Build → Launch → Look after it.
- "How portable is the completed system?" Look for documentation, a clean handover and a build you can take with you.
- "Can you show me something working?" A live demo or walkthrough of a working build carries more weight than a sales deck.
Put these to every agency on your shortlist and compare the answers in writing.
Evidence a credible agency should provide
- A measurable delivery commitment. The agency should agree what the build will do and how the result will be checked. Revenue and ROI remain commercial outcomes rather than guaranteed figures.
- A named process. You should be able to see every stage from signing to launch before you commit.
- Evidence behind each logo. Ask what was built, what changed and whether the example is a named client or an illustrative scenario.
- A clear split between AI and human judgement. The agency should name the tasks AI handles, the checks a person performs and the escalation path.
- Accounts and logins held by you. The system should run on your accounts from day one.
Where our model fits
We fit UK small and mid-sized businesses that want a specialist team to handle the build. You describe the task in your own words (chasing invoices, answering the same customer emails or moving data between tools) and we build it, run it, and report back.
Other routes fit these situations:
- Large enterprise programmes are best matched with a systems integrator built for security review teams, procurement frameworks and multi-year programmes.
- In-house capability is best served by hiring or training for it, starting small with a DIY tool like Zapier and owning the skill internally.
If you're building in-house, the checklist above still works. Point the questions at your own plan.

How much does an AI automation agency cost in the UK?
Illustratively: £500–£2,500 for discovery or a pilot, £2,000–£10,000 for a single fixed-scope build, £10,000+ for multi-system work, and £500–£3,000+ per month for a retainer. Integration complexity drives the price. Full breakdown: AI automation costs in 2026.
How long does a build take?
A single-process, fixed-scope build typically takes a few weeks. Multi-system builds take longer. Look for a written timeline in the quote.
How much technical work will I handle?
A good agency takes a clear description of the work you want handled and manages the tools, build and maintenance. Your job is describing the task and signing off the result.
Should I build it myself with Zapier?
Yes, for a simple two-app job, DIY can be the best-value route. See the full comparison: DIY Zapier vs hiring an automation agency.
