On Premises AI London: One Machine, Installed at Your Office
Not a server room. One machine, sized for your team, installed on your network at your London premises by the people who will support it — and nothing for your IT contractor to run.
£500 per month for the software and the hardware rental. You rent the machine — you don’t buy it.
On premises AI in London means a dedicated AI machine installed inside your own office rather than a cloud service, so documents and conversations never leave the building. We specify the machine, install it on site anywhere in Greater London, connect your existing sign-in, import your documents and support it on an ongoing arrangement.
Find out what machine London firms need
A short call to size the machine and check the site. If a hosted agent would serve you better, we will say so.
The whole system at your London office: one machine, sized for the team, 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.

On-Premises Versus Cloud Versus Building Your Own
Three routes to the same goal for London firms. Only one leaves you without a server to look after.
| Cloud AI subscription | Build your own on premise AI server | Our on-premises AI in London | |
|---|---|---|---|
| Where your documents are processed | The provider’s servers | Your building | Your building |
| Hardware | None | You research, buy and configure it | One machine, sized for you and rented, not sold |
| Installation | Sign up | Your IT person’s project | Done by us, in London |
| Updates and model upgrades | Automatic, on their schedule | You | Us, as part of support |
| When it breaks | Their status page | You | Restored from backup by us |
| Time to live | Days | Open-ended | Weeks, not months |
What Turns Up at a London Office, and What Does Not
London businesses hear “on-premises” and picture a comms room they do not have, a cooling problem and a contractor day rate. What actually arrives is one machine, specified after a short call for the number of people who will use it and the size of the document set, that sits on a shelf or under a desk on your own network. In a City office where every square metre is priced, that matters more than it does anywhere else in the country.
The install is done by us, at your premises. Serviced offices and multi-tenant buildings around the City, Holborn and Canary Wharf are common, and they change one thing: we check how your network is segmented from the building’s before the machine is delivered, so it sits on yours and only yours. That is a ten-minute conversation on the first call, not a surprise on install day.
On the machine run open-weight models — models whose weights are published so they can run on your hardware rather than only through a provider. Around them sit the tools your team actually uses: a private chat assistant, document spaces that search and summarise across hundreds of files with a citation to the page, and custom assistants for the recurring jobs. Your team sign in with the Microsoft 365 or Google Workspace accounts they already have.
What does not turn up is a project for your IT person. Supply, installation, sign-in, document import and training are ours; software updates, model upgrades and support are ours on an ongoing arrangement, from the people who did the install. For a London firm paying London rates for outsourced IT, that is usually the line that settles it.
One On-Premises AI System, Three Things It Does
Every part of the system runs on the machine in London.
Private chat
A ChatGPT-style assistant on your own machine. Ask questions, upload documents and images, work through drafts — without any of it going to an outside service.
Document spaces
Organise files and correspondence into spaces. Search, summarise and compare across hundreds of documents, with citations to the page each answer came from.
Custom assistants
Automations built around your workflows — recurring reports, standard memos, routine checks — running on the same machine as everything else.
| Document | What a London team asks for | What stays where |
|---|---|---|
| Client files under restrictive engagement terms | Search, summarise, draft against | On the machine, in your office |
| Cross-border matter correspondence | A chronology or summary, cited to the page | On the machine, in your office |
| Contracts and agreements | What clause 14 says; the differences between versions | On the machine, in your office |
| Patient or client correspondence | A draft reply in your wording | On the machine, in your office |
| Internal policies and templates | Find it, cite it, draft from it | On the machine, in your office |
| Your practice, case or CRM system | Not connected — remains the system of record | Your existing system |
From First Call to a Machine at Your London Premises
Weeks, not months. Most London clients start with one team — one practice area, one 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 serviced offices and shared buildings, check how the network is arranged.
Install at your premises
The machine goes on your network anywhere in Greater London. Single sign-on connects to your Microsoft 365 or Google Workspace and your documents are imported into spaces.
Train on site, then support
We train the people using it at your office, 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
An on-premises machine is built for confidential, document-heavy work. Call answering and inbox triage are better served by our hosted agents, which need no hardware and are live in days. Plenty of London firms 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.
Built by People Who Run Their Own
One arrangement covers it
Machine, installation, training and ongoing support from one team. No hand-off between a hardware supplier, a software vendor and an IT contractor.
Rented, not sold
The machine is specified for your team and its open-weight models after a conversation, then rented to you with the software for £500 a month. Start with one team; adding people later is configuration.
UK data protection built in
No third-party AI processor and no restricted transfer for the AI step. UK GDPR and the Data Protection Act 2018, the ICO as regulator, and a data processing agreement for the support access you grant us.
Honest about the trade
Local models are capable and a little slower than the biggest cloud services. We say so up front, and we will tell you if a cloud agent is the better fit.

On-Premises AI in London: Common Questions
What is on premises AI?
A system where the AI models run on hardware inside your own building instead of on a provider’s servers. Your documents, prompts and chat history stay on that machine. Ours is a dedicated computer we supply, install in London and support.
What hardware does an on premise AI server need?
It depends on how many people use it and how large your document set is. We size and specify the machine for you after a short call — the same conversation decides which team goes first.
How much space does an on-premises AI machine need in a London office?
A desk corner or a shelf. It is one machine, specified for your team, not a rack. Central London floor space is expensive and we are asked this first; the answer is that it takes less room than a printer.
Do you install across all of Greater London?
Yes — the City, Canary Wharf, the West End, and the boroughs out to Croydon, Richmond and beyond. The machine is delivered and installed on your network at your premises, and your team is trained on site.
Do you install 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. A question for the first call, not a blocker.
How much does Local AI cost?
£500 per month for the software and the hardware rental. The dedicated machine is rented to your business, not sold: you never buy the hardware. It is installed in your building and runs the private chat, document spaces and assistants. Local AI is for business customers only.
