AI automation agency UK.

Every business runs on repetitive work that no one enjoys and no one has time to fix. Data copied between systems that do not talk. The same email chased for the tenth time.

Reports rebuilt by hand every Monday. A document read, retyped and filed. It is the work that quietly absorbs a day a week from people you hired to do something more valuable, and it never quite reaches the top of anyone's list to sort out.

Sizrok is a UK AI automation agency that builds bespoke automations to take that work off your team. We are not a software product you subscribe to and we are not a generalist shop that automates anything for anyone.

We build and maintain custom AI agents and workflows around the tools you already run, in the sectors we actually know, and we start by finding the one process that is costing you the most. If a bespoke build is not the right answer, we will tell you that too.

That combination, deep in a handful of industries and honest about what automation can and cannot do, is what separates us from the crowded field of agencies promising to automate everything and proving nothing.

What an AI automation agency actually does

An AI automation agency finds the repetitive, procedural work inside a business and builds software that does it, so people do not have to.

In practice that means a short sequence: audit how work actually flows through the company, identify the manual tasks that cost the most time or cause the most errors, build AI agents and automations to carry that work, connect them to the systems you already use, and then maintain the whole thing as the business changes.

The distinction worth understanding is between buying a tool and getting a build. A tool is a fixed product you adapt your process to fit. A bespoke build is the reverse: automation shaped around how your business already works, wired into your existing stack, doing your specific tasks.

A good agency does the second, and is honest enough to point you at an off the shelf tool when that genuinely would serve you better and cheaper. For the wider picture on the technology underneath this, our complete guide to AI agents goes deeper.

What we build

We build a small set of things well rather than a long menu of everything.

AI agents

that carry a whole task end to end, watching for a condition and acting on it, escalating to a person when judgement is needed.

Workflow automation

that moves work between your systems, so the handoffs that people currently do by hand happen on their own. Our work on reducing repetitive admin covers this in depth.

Chatbots and voice agents

that handle routine enquiries and calls in your own tone, book and reschedule against a live diary, and pass the rest to a human.

Document processing

that reads, extracts and files the information locked in PDFs, forms and emails, so it stops being retyped. See automating document processing.

CRM and data integration

that connects the tools that do not talk to each other, so a record entered once flows everywhere it needs to.

These are the building blocks. What we actually deliver is a combination of them shaped around one of your workflows, as AI automation services built for your business rather than sold from a shelf.

Industries we specialise in

The thing most agencies cannot say is that they know your industry's workflows. We can, because we have built for them. Specialisation is the difference between automation that survives contact with how your sector really operates and automation that breaks the first time reality does not match the demo.

We build for transport planning, where proof of delivery collection and invoicing throttle a haulier's cash flow. For estate agents, where enquiries, viewings and chain admin swallow negotiator time. For recruitment agencies, where the whole desk, not just the shortlist, needs support.

For manufacturing, where the office admin behind the shop floor is often the real bottleneck. Each of those pages sets out the specific workflows we automate in that sector, and they are the clearest proof we bring that we know real work, not generic "AI for everything".

What this looks like in practice

Because proof matters more than promises, here is the shape of the work rather than a list of claims.

A logistics operator was losing days to chasing proof of delivery before it could invoice.

We built an automation that chases the document the moment a delivery is due, captures it however the driver sends it, matches it to the job in their transport system and prepares the invoice for a person to release.

The cash that was stuck waiting on paperwork started moving on the same day instead of days later.

A professional services firm was drowning in the same client details being keyed into three systems at onboarding. We connected those systems so the information is captured once and flows everywhere it belongs, and the file a reviewer needs is assembled as the work happens rather than rebuilt afterwards.

An operations team was rebuilding the same management report by hand every Monday, pulling numbers out of four tools into a spreadsheet before anyone could act on them.

We had the report assemble itself overnight, so the week now opens with the figures ready and the morning that used to disappear into copy and paste goes to the decisions the numbers point to.

None of these are dramatic rip and replace projects. Each started from one workflow that was quietly costing more than anyone had stopped to measure, and each left the rest of the business untouched. That is deliberate.

A narrow, well chosen first build proves the value on real work before anything bigger is committed, and it is far easier to trust an automation you have watched handle your own cases for a fortnight than one sold to you on a slide.

We keep these examples honest and qualitative on purpose. Rather than quote a headline percentage we cannot stand behind for your business, we would rather show you, at the audit, the specific hours your own workflow is leaking and what removing that would be worth.

The context for how common this problem now is: the Office for National Statistics found that around 21% of UK businesses were using AI by mid-2025, rising to more than a third of larger firms, which means the businesses that get the internal build right are pulling ahead of the ones still doing it all by hand.

What it costs

We will not pretend there is one price, because there honestly is not.

What determines the cost is the shape of the work: how many systems the automation has to touch, how complex the logic is, how much data flows through it, and whether it is a single workflow or a connected programme across several.

As a rough map, the smallest sensible engagement is a single workflow build, one clearly defined process automated and integrated. A wider programme that wires several workflows together across your stack is a larger piece of work.

Rather than quote a number that turns out to be wrong, we give you a fixed price at the audit once we have seen the actual workflow, and we size it against the real alternative, which is usually hiring to absorb the manual work or stacking more subscriptions.

If the build does not pay that back within a sensible window, we say so before anything is scoped. Honesty about cost is the differentiator here, not a hidden quote you have to book a call to prise out.

How to choose an AI automation agency

If you are shortlisting, a few questions separate the agencies worth your time from the rest.

Ask about the delivery model. Are they building something bespoke around your systems, or reselling a fixed tool with their logo on it? Both are valid, but you should know which you are buying.

Ask about specialisation. Can they name the workflows in your industry, or do they automate "anything"? Depth beats breadth every time automation meets a real process.

Ask for proof, and be wary of round numbers with no story attached. Ask about pricing, and treat a refusal to give any range as a signal. And ask what happens after launch, because an automation no one maintains slowly stops matching the business and quietly dies.

The other question worth asking is what the agency will not do. A shop that says yes to every sector and every request is telling you it has no particular expertise in yours, and generic capability is exactly what falls apart when your process does something a demo never anticipated.

An agency that occasionally tells a prospect their problem does not need a custom build is one whose recommendations you can actually trust, because it has shown it is not simply selling whatever it happens to make.

We put ourselves forward on exactly those terms: bespoke builds, genuine vertical depth, honest proof and pricing, and ongoing support rather than a handover and goodbye. We would rather lose a pitch to an honest comparison than win one on a claim we cannot back.

How we work

01 Discovery and audit.

We sit with your team and trace one workflow end to end, finding where the time and errors actually accumulate.

02 Map the work.

We set out the repetitive steps, the handoffs between tools and the points where a person must stay in the loop.

03 Build.

We build the bespoke automations and agents to carry the work.

04 Integrate.

We connect them to the systems you already run rather than standing up something new to learn.

05 Test on live work.

We run it against real cases, with your people checking the output, until it is reliable.

06 Handover and support.

We hand it across with training, and stay on to maintain and extend it as the business and the tools change.

Talk to us about your UK operation

If repetitive work is eating your team's week, that is exactly what we build to remove. We will look at one workflow, tell you honestly whether a bespoke automation pays for itself, and if it does, build it around the systems you already run and maintain it as you grow.

There is no obligation and no pressure. Sometimes the honest answer is an off the shelf tool or a small process change rather than a build, and when that is true we will say so.

And when a custom automation is worth building, you will leave the call understanding the reasoning, the price and the hours it hands back to your people.

Common questions about hiring an AI automation agency

An AI automation agency finds the repetitive, procedural work in a business and builds software to do it. A good one audits your workflows, builds AI agents and automations around your existing systems, integrates them, and maintains the result, so your team spends less time on manual admin and more on the work that needs a person.
Look at the delivery model (bespoke build versus resold tool), genuine specialisation in your industry, real proof rather than round numbers, transparency on price, and what support you get after launch. An agency that knows your sector's workflows and maintains what it builds will serve you far better than a generalist.
We work with businesses across the UK, so wherever you are, there is. Most of the work is done remotely, with on site time where it genuinely helps, and our local pages cover specific cities and regions. Distance is rarely the deciding factor; industry knowledge and delivery model matter far more.
Yes. We act as AI automation consultants for businesses throughout the UK, starting with an audit of where your time is going before anything is built. Being close by matters less than whether the consultant understands your workflows and is honest about what is worth automating and what is not.
Sizrok works with SMEs across the UK, from a single automation to a full programme. The best starting point is not proximity but a discovery call, where we look at your actual workflows and tell you plainly whether a bespoke build pays for itself for your business.
