Local AI London: Confidential Files That Never Leave the Office
London firms handle the most sensitive material in the country for the most demanding clients, on the most expensive floor space. A private AI machine installed at your premises fits on a desk and keeps every document in the building.
£500 per month for the software and the hardware rental. You rent the machine — you don’t buy it.
Local AI in London is a dedicated AI machine installed at your own premises, running open-weight models so client documents and conversations never reach a cloud provider. We specify, install and support it on site across Greater London, from City law firms to Harley Street clinics, with private chat, document search and assistants.

A short call first, then a site visit if it makes sense. If a hosted agent would serve you better, we will say so.
One machine at your London premises, running private chat, document spaces and assistants on your own network.
Cloud Agents for the Phone and Inbox, Local AI for the Files
Many London businesses pair the two: hosted agents answering calls and sorting email from day one, and a Local AI machine on site for anything that must not leave the office.

Cloud AI Versus a Machine in Your Own Office
The confidentiality problem is the same everywhere. In London it arrives with international clients, stricter engagement terms and rents that make any hardware question a floor-space question.
| Cloud AI service | Local AI at your London premises | |
|---|---|---|
| Where client documents are processed | The provider’s servers, often outside the UK | Your building |
| Cross-border client data | A transfer to justify, per provider | No transfer — it never leaves the room |
| Contracts forbidding third-party processing | A conversation with the client, per tool | Not engaged — there is no third party |
| Floor space needed | None | A desk corner — one machine |
| Works if the connection drops | No | Yes — only sign-in needs the internet |
| Installation | Sign up | On site, by us |
| Time to live | Days | Weeks, not months |
Why London Firms Ask for On-Premise AI First
The London businesses that ring us about private AI in London have usually already tried to sign off a cloud tool and stalled. A City firm acting on a cross-border matter finds the other side’s documents are under an express restriction on third-party processing. A Harley Street clinic finds its patient correspondence cannot casually go to a provider whose servers are somewhere else. A Mayfair adviser finds a client who simply asks, in a meeting, where the files go — and wants an answer shorter than a transfer risk assessment.
On-premise AI in London answers that question in one word. The model runs on a dedicated machine on your own network. Documents, prompts and chat history are stored on it. The only outside connection is to your own Microsoft 365 or Google Workspace account for sign-in. When the client asks where the files go, the answer is: nowhere.
The second London-specific question is space. Central rents make people wary of anything described as a server, and the picture in their head is a rack and a cooling problem. In practice it is one machine, specified for the team, that fits on a desk or a shelf. Serviced offices and shared buildings need one extra check on how the network is segmented, which we make on the first call.
The third is people. London IT contractors are expensive and busy, and a self-run server project competes with everything else on their list. Our arrangement covers the machine, the install at your premises, the training and the ongoing updates and support, so nothing lands on your IT person’s list at all.
Across London’s Professional Districts
One arrangement covers the machine, the on-site install, the training and the support.
Law firms and chambers
Around the Inns, Chancery Lane and the City, where matter files, counsel’s advice and privileged correspondence need searching without ever reaching a provider.
Private clinics and practices
Harley Street and Marylebone medical, dental and cosmetic practices with patient correspondence, referral letters and treatment plans that stay in the practice.
Advisers and agencies
Accountants, wealth advisers, HR consultancies and agencies from Mayfair to Shoreditch holding client papers that contracts say must not leave the firm.

From First Call to a Machine at Your Premises
Weeks, not months. Most London clients start with one team — one practice area, one clinic department — and widen from there.
Size and check the site
A short call on who will use it and what it will read. We specify the machine and, for shared buildings, check how the network is arranged.
Install on site
The machine goes on your network at your premises. Single sign-on connects to your Microsoft 365 or Google Workspace and your documents are imported into spaces.
Train and support
We train the people using it on site, then keep the software updated and the models current, with support from the people who did the install.
Where Local AI Is the Wrong Answer
We would rather lose the enquiry than the trust. Three things we tell every prospect before they sign anything.
It is not the answer for the phone or the inbox
A machine at your premises is built for confidential, document-heavy work. Call answering, inbox triage and lead follow-up are better served by our hosted agents, live in days with no hardware. Plenty of London clients run both.
It is slower than the big cloud models
Open-weight models on a single machine are capable for summarising, drafting and answering questions about your own documents. For frontier reasoning on hard, novel problems, the largest cloud models are still ahead. That is the trade.
It is a weeks-long install, not a sign-up
A cloud agent is live in days. Local AI needs the machine specified, delivered, installed on your network and your documents imported. Weeks, not months — but not tomorrow.
A UK Team That Comes to Your Office
Installed at your premises
Specified, delivered, installed and trained on site anywhere in Greater London. No server project for your IT contractor.
Fits the floor space
One machine on a desk or a shelf, sized for the team, not a rack.
Built for London engagement terms
No third-party AI processor and no restricted transfer for the AI step under UK GDPR — the two things cross-border clients ask about first — and a data processing agreement for the support access you grant us.
Honest about the trade
Local models are capable and somewhat slower than the largest cloud services. We say so before you sign anything.

Local AI in London: Common Questions
Do you install Local AI on site in London?
Yes. The machine is specified after a short call, then installed on your network at your premises anywhere in Greater London. We connect your existing Microsoft 365 or Google Workspace sign-in, import your documents and train your team on site.
We are in a serviced office. Does that matter?
It is worth raising early. The machine sits on your own network segment, and in a shared building we check how that network is arranged before the install. It is a question for the first call, not a blocker.
Is private AI in London different from anywhere else?
The product is the same. What differs is the client base — international matters, cross-border data, contracts that forbid third-party processing — and the cost of floor space. A machine that fits on a desk and keeps everything in-house suits both.
Can our staff use it from home?
The machine lives at your premises and is used over your own network, in the office or over whatever connection your firm already uses to reach its own systems. How that is set up is part of the install conversation.
How long does a London install take?
Weeks, not months. The machine is specified, delivered and installed, documents imported and the team trained. Most clients start with one team and widen the rollout once it is in daily use.
How is it priced?
£500 per month for the software and the hardware rental. The machine is rented to your firm, not sold, so there is no hardware purchase up front. We still size it for your team on a short call.
