AI Agent Development Company in the UK: Agents Built With the Brakes On
An AI agent reads a request, decides what to do and acts inside your systems, then reports back. HAeX is an AI agent development company for UK businesses. We build agents that do real tasks with limits, logs and a person to sign off. Price is scoped on a call after the audit.
- Every agent has limits you set.
- A person signs off the actions that matter.
- Every build has a UK GDPR and data flow note.
An AI agent is software that is given a goal, works out the steps and carries them out using your tools. A chatbot talks. An agent does.
What is an AI agent, in plain terms?
For example, an agent can read a supplier email, check the order, update your records and draft a reply. It chooses the steps itself within the limits you set.
Do I need an AI agent for my business?
You need one if the task needs judgement across several steps and a plain rule does not cover it. If a rule is enough, you do not need an agent.
Good candidates are handling a support inbox, preparing a client file or qualifying enquiries. Poor candidates are tasks with no clear rules and no data. We tell you honestly which one you have. Many firms need AI automation first.
Is an agent better than a chatbot or an automation?
It depends on the task. A chatbot answers questions, an automation follows fixed steps and an agent chooses its steps. Use the simplest one that works.
| Tool | Best for |
|---|---|
| Chatbot | Answering questions from approved information |
| Automation | Fixed steps that always run the same way |
| Agent | Several steps that depend on what it finds |

AI agents development
What kinds of agent do you build?
We build agents for support, operations, sales and records. Voice agents are a separate service.
Examples include:
A support agent that triages and drafts replies
A document agent that reads, checks and files
A sales agent that qualifies enquiries and books calls
A back office agent that chases open tasks
A voice agent that answers or makes calls
If your need is calls, see the AI Receptionist.
Here is a worked example with assumed figures. It is not a client result.
What does a worked example look like?
Say a support inbox gets 50 emails a week. Someone reads each, finds the order and drafts a reply, at 8 minutes each. That is 400 minutes, or about 6 hours 40 minutes a week. An agent reads the email, looks up the order and drafts the reply. A person reads each draft in about 2 minutes.
We can work through this with your own details on a free call.
What stops an agent going wrong?
Limits, logs and a person. We give each agent only the access it needs, record every action and require sign off for anything that cannot be undone.
For example, an agent can draft a refund but not issue one. It can propose an email but not send it until a person agrees. You choose the limits and can tighten them at any time.
How does a project run, step by step?
It runs in four steps.
- 1
Discovery call (30 minutes)
You describe the task and the data.
- 2
Audit and quote
We test whether an agent suits the task and quote in writing.
- 3
Build (2 to 6 weeks)
We build, test on real cases and show you every action.
- 4
Run and improve
We review the log with you and tighten the rules.
It can be. Every build has a UK GDPR and data flow note, a DPIA where needed, and named sign off points.
Is it safe under UK GDPR?
Agents that make decisions about people need extra care, because UK law limits solely automated decisions. We keep a person in the loop for those. See AI governance and compliance for a policy and assessment.
What does an AI agent development company charge, and how long does it take?
Price depends on the task, the systems and the checks. We scope it after a free call and the audit, and quote in writing.
Most builds take 2 to 6 weeks, and larger agents take longer. If you also need your agent to reach your own software, see AI integration. For fully custom software, see AI development.
If you want the agent built on Claude, see Claude AI integration. If it needs a full app around it, see AI software development.
What is the next step?
Book a free call and describe the task you would give a new assistant on day one. We will say whether an agent, an automation or a person is the right answer.
If an agent is not the right fit, we say so.
Questions that come up
What is the difference between an AI agent and a chatbot?
A chatbot answers. An agent also acts, using your systems, within limits you set.
Are AI agents safe for business use?
They can be, with limits, logs and human sign off. We do not give an agent more access than it needs.
What does an AI agent development company charge?
It depends on the task. We scope it on a call and quote in writing before we build.
Which AI models do you use?
OpenAI and Claude, chosen by task. We tell you which and why.
Can an agent make mistakes?
Yes. That is why we log every action and keep a person on anything that cannot be undone.
Can you add an agent to our existing systems?
Yes, through their connections. If a system has none, we say what the options are.
