Hiring an n8n automation agency in the UK looks simple until the quotes arrive. One agency lists a single workflow from £250, another quotes £3,500 to £12,000 for the same kind of build, and a third wants a £2,500 monthly retainer before anything is built. The spread is real, and it comes from what each price includes rather than from the n8n software itself. This guide explains what an n8n automation agency in the UK charges, which pricing models exist, what the n8n platform costs on top, and how to compare quotes. Prices come from n8n's own pricing page and from agency pages read on 9 November 2026. Agency prices are self-published and change often, so they are indicative only, not a quote.
Key takeaways
- A UK comparison of agencies that publish prices found first workflows or single agents from £250 up to £15,000, with a median of £2,125.
- Retainers vary even more, from care plans of about £99 to £495 a month up to £2,500 a month for hosting, support and new builds.
- The n8n platform itself is a small part of the bill: n8n Cloud's Starter plan is $20 a month and Pro is $50 a month, billed annually.
- Self-hosting n8n is not free of cost: a server, backups, monitoring and updates still need paying for.
- n8n's Sustainable Use License limits use to a licensee's own internal business purposes, so an agency that hosts n8n for clients should explain how its set-up is licensed.
What an n8n automation agency does
n8n is a workflow tool that connects apps and moves data between them, for example turning a website enquiry into a CRM record, an invoice reminder and a message to the sales team. An agency designs these workflows, builds them in n8n, connects the client's accounts, tests them, handles errors and usually hosts or monitors the instance. Many also add AI steps, such as reading an email and drafting a reply. The same work can be done in-house, but a small business often lacks the time to learn the tool, so it pays someone else to set it up and keep it running.
What UK n8n agencies charge
A UK comparison published by Augustova, which is itself an agency, collected the prices that agencies list on their own sites. It reports that UK agencies charge from £250 to £15,000 for a first workflow or single agent, with a median of £2,125, and about £1,500 for an audit. Entry-level specialists start under £1,000, while firms that build AI systems in code start at £6,000 to £15,000. Individual listings in that comparison give a feel for the range:
- An agency in Andover lists n8n workflows from £250 with setup included.
- A Glasgow agency lists a single workflow from £750, with most clients spending £1,500 to £15,000 and maintenance from £150.
- A London agency lists workflow implementation of £3,500 to £12,000 and a retainer of £1,000 to £3,500 for 10 to 40 hours.
- A Manchester agency lists workflow automation of £500 to £5,000.
- Another London agency lists a simple workflow from £1,500 with care plans from £99.
A separate UK agency, AI Automate Company, states on its n8n page a monthly retainer from £2,500 covering ongoing support, hosting and new workflow builds. These figures come from marketing pages and comparison articles, so they show the market's shape, not a guaranteed price.
The four pricing models
Fixed price per workflow
The agency quotes one price for one defined workflow. This is the easiest model to compare, and it suits a clear task such as syncing form entries to a CRM. The risk is scope: a workflow that looks like one step often hides five, such as duplicate checks, error handling and approvals. Always ask what counts as one workflow.
Project price for a system
Several connected workflows are quoted together, often after a paid audit. The Augustova comparison shows audits at around £1,500, sometimes credited against a later build. This model fits a business that wants sales, invoicing and reporting joined up.
Monthly retainer
The client pays each month for hours, support and changes. Retainers range from small care plans to several thousand pounds. The important question is what the money buys: a block of hours, a guaranteed response time, hosting, or only monitoring.
Hourly or day rate
Some freelancers and agencies bill time. This works for small fixes, but the final cost depends on how well the work is specified.
What the n8n platform costs on top
n8n states that all its plans include unlimited users and workflows and that pricing depends on monthly workflow executions. At the time of reading, the pricing page showed the Starter plan at $20 a month, billed annually, with 2,500 workflow executions, and the Pro plan at $50 a month, billed annually, with 10,000 executions. The currency shown can vary by visitor. Higher tiers exist for larger companies. Small businesses rarely pay more than this for the platform, which is why the agency's time dominates the cost.
The alternative is self-hosting. The software can run without a licence key as the free Community edition, but the business or agency then pays for a server, backups, monitoring, security updates and someone to fix it when it breaks. The Community edition also lacks features such as projects, single sign-on and Git version control according to n8n's comparison page.
The licence question agencies should answer
n8n's source code is published under the Sustainable Use License. Its text says the software may be used or modified only for the licensee's own internal business purposes or for non-commercial or personal use, and that it may be distributed to others only free of charge for non-commercial purposes. In plain terms, the licence does not obviously allow an agency to run a paid n8n service for clients on a free Community install. The licence text does not name hosting for clients either way, so the safe step is to ask the agency which n8n plan or licence covers the client's instance and who owns the account. That question protects the client if the arrangement changes later. It is a licensing point for the agency and the client to settle with n8n, and this article does not give legal advice on it.
Hidden costs to ask about
- Third-party subscriptions: CRM, email, accounting and AI model fees are charged separately and often grow with usage.
- AI usage: workflows that call a language model pay per request, so costs rise with volume.
- Maintenance: apps change their APIs, and a workflow that worked in January may need a fix by June.
- Ownership: check who owns the instance, credentials and workflow files, and whether they can be exported.
- VAT: some agencies quote including VAT and others add it afterwards.
- Documentation: a workflow nobody can explain is expensive to hand over or repair.
How to compare quotes
- Write the process down first in plain steps, including who approves what and what happens when it fails.
- Ask for scope in writing: number of workflows, apps connected, error handling, testing and a handover.
- Separate build from run: one price for the build and a separate, clear price for hosting and support.
- Ask about hosting and licence: where the instance runs, who pays for it and which n8n plan covers it.
- Check references and ask for a live example of a similar workflow.
- Start small: a single, valuable workflow shows how the agency works before a retainer begins.
What a first project usually looks like
A sensible first project follows the same steps whichever n8n automation agency is chosen. The agency starts with a discovery call or paid audit to map the current process and pick one workflow with a clear payoff, such as lead capture, invoice chasing or appointment confirmations. It then agrees the scope in writing, sets up the n8n instance and credentials, builds the workflow, and tests it with real examples, including bad data and failed connections. After launch, it monitors runs for a period, fixes problems and hands over documentation. Businesses that skip the audit and the testing steps often pay twice, once for the build and again for the repair.
Ask the agency to show how failures are reported. A good set-up tells a named person when a run fails, keeps a log of what happened and retries safely instead of sending duplicate emails or invoices. These details rarely appear in a price list, but they decide whether a cheap workflow stays cheap.
When to do it yourself and when to hire
A technically confident owner can build simple workflows on n8n Cloud for the price of the plan. Hiring starts to pay off when the workflow touches money, customers or compliance, when it has to run reliably without anyone watching, or when the team has no time to learn the tool. Teams unsure which tool to use can first read this comparison of n8n, Zapier and Make, since the cheapest agency is the wrong choice if the tool does not fit the job. Businesses that want automation tied to a chat channel can also read about a WhatsApp AI chatbot for business.
Some automation needs go beyond a no-code tool: custom logic, a database, a customer portal or a product other people will use. For that, CreativeIn Tek builds AI and automation solutions alongside its custom software work, and agencies of any size should be judged the same way: by scope, ownership and support, not by headline price. CreativeIn Tek does not publish a UK price list, so none is quoted here.
Frequently asked questions
How much does an n8n automation agency cost in the UK?
Published prices range from about £250 for a basic workflow to £15,000 for complex builds, with a median first-workflow price of £2,125 in one UK comparison. Retainers run from about £99 a month up to £2,500 or more.
Is n8n free?
n8n can run for free as the Community edition when self-hosted, but hosting, backups and maintenance cost money. n8n Cloud plans start at $20 a month billed annually, according to its pricing page.
Can an agency host n8n for me on the free version?
The Sustainable Use License limits use to internal business purposes or non-commercial use. Ask the agency which plan or licence covers your instance before signing.
Do I need a retainer?
Not always. A simple workflow may need only a build fee and a small care plan, while systems that change often justify a retainer with defined hours and response times.
How long does a workflow take to build?
It depends on scope. Some agencies state a first build in about a week, and others quote one to three weeks for larger pieces, so ask for a dated plan in writing.
