Most AI consulting in the UK is sold by the day, and the first invoice arrives before anything works
Search for an AI consultancy and you find two kinds of firm: large practices whose minimum engagement starts well above what a mid-sized company wants to risk on a first project, and agencies that sell strategy decks and workshops before any code exists.
We started Kelriva because we had sat on the buying side of that. So we publish our prices, scope in writing before we start, and measure ourselves on whether the system is running in your business at the end, not on hours billed.
We are small, and we say so. That is a feature for the size of project we take on and a limit for the ones we do not.
Four things to check any UK AI consultancy against
Three things, done properly
Intelligent document processing
Extraction from contracts, KYC packs, compliance filings and invoices, with every field traceable back to the source page and a review step for anything the model is unsure about.
Details →AI workflow automation
Multi-step LangGraph agents that replace manual approval chains and coordination work, with human-in-the-loop controls and a full audit trail.
Details →Data analytics and intelligence
Pipelines, warehouses and dashboards that turn scattered operational data into something a manager can act on, including predictive views where the data supports them.
Details →From a first call to a system your team runs
A conversation
Thirty minutes on what is still done by hand, what it costs, and what a working system would need to prove. If we are not the right fit, we say so on the call.
A written scope and a fixed price
You get a one-page scope with the deliverables, the timeline and the fee. Nothing starts until you have signed it.
Build in the open
Working software every week, on your infrastructure, with your team looking over our shoulder. Problems surface early instead of at handover.
Handover and a reference
Documentation, source code and training. Then, if it went well, we ask whether you would take a reference call from the next client.
Tell us what is still done by hand
One call is enough to scope it. You will have a written price within 48 hours, and a clear no if it is not a fit.
Book a 30-minute callChoosing an AI consultancy in the UK: what buyers ask us
What does an AI consultancy in the UK typically charge?
Most UK AI consultancies and agencies price by the day or by a retainer, so the final cost is hard to know before work starts. We publish fixed starting prices instead: an AI Strategy & Roadmap from £3,500, a Document Automation pilot or AI Agents & Workflow Automation from £15,000, and a Custom AI Build from £40,000, each scoped in writing before work begins.
Are you based in London?
Yes. Kelriva AI Limited is registered in London and the two of us work with clients across the UK, mostly remotely, with on-site sessions where a project needs them.
How big is the team?
Two people, and we say so up front. It means the people you speak to on the first call are the people who build the system. It also means we take on a small number of engagements at a time and turn work away when we are full.
Do you have a live reference client?
Yes. bettercoach runs our AI-assisted coach matching engine in production. Their Managing Director has described the engagement publicly and is available for a reference call. The full case study is on this site.
Which industries do you work with?
Fintech and financial services, ESG and sustainability reporting, corporate finance and private equity, and corporate coaching and learning. The common thread is document-heavy, regulated work where a wrong answer has a cost.
What if we are not sure we are ready for AI?
Start with the AI Strategy & Roadmap. It scores six dimensions of your organisation, tells you honestly what to build first, and what not to build at all. If you then commission a build within 90 days, half of the fee is credited against it.
