On-Premise LLM Deployment in London
The best On-Premise LLM Deployment in London, at the best available price.
You have the GPU and you have the model. What is missing is the leg in between: the model exposed as a reliable private API, reached securely from your application, returning data you can trust. That is the whole engagement.
London is Europe's largest technology and finance hub, with fintech, AI labs, insurers and banks concentrated in one city. Buyers are sophisticated and well funded, and almost every serious one asks early where data is processed and how AI decisions can be explained.
London banks, insurers and their suppliers are asked where AI processing happens and who can see the data. A private deployment in a UK region of your own cloud account gives a clean answer for UK GDPR and for the FCA.
What you get
- vLLM serving tuned to your GPU: quantisation on the native kernel path, KV cache sizing, continuous batching, prefix caching
- A private network path with no public exposure, verified as a direct peer connection rather than a relay
- Schema-constrained responses plus a deterministic QA gate, so a wrong answer is rejected rather than rendered
- Documented baseline: tokens per second, time to first token, real concurrent capacity
- Infrastructure as code in your repository, a runbook, and every credential held by you
No upfront payment and no escrow required. You hold every dollar until a checkpoint is delivered and accepted, and thirty days of defect correction is included. Scope and price are set on a call.
Invoiced in USD or GBP, payable by Wise or bank transfer.

You speak to the engineer who does the work. No sales rep, no deck.
Who builds here
AI Development Company
London has more demand for AI product work than almost anywhere in Europe, and most of it has to hold up in front of regulated customers, which is the kind of AI engineering we do.
What London companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Fixed-fee assessment
Five business days from the day access is in place. Your stack examined end to end, existing work classified as preserved or replaced with reasons, the connection design, and acceptance criteria written as testable statements.
Implementation in checkpoints
Around three weeks. Each checkpoint has written acceptance criteria agreed before work starts, and is invoiced only after you accept it. Appoint an independent technical reviewer if you want one.
Handover and closeout
One real request through your real application, on synthetic data, passing every QA rule. Runbook, recorded handoff, and all our access removed with written confirmation.
What actually applies here.
Regulation and data
UK GDPR and the Data Protection Act 2018 govern personal data, and the Data (Use and Access) Act 2025 relaxes some rules on automated decision-making while keeping safeguards such as the right to human review of significant decisions. Financial firms answer to the FCA, whose Consumer Duty and operational resilience rules shape what they can outsource and how AI outcomes are monitored. The UK has no single AI statute; regulators apply their existing rules to AI.
Contracting and payment
You contract with an individual consultant based in India, not a UK company. Invoices can be issued in GBP or USD and paid by Wise or bank transfer. Your accountant will treat an overseas supplier in the usual way; any paperwork they need is provided before work begins.
Working hours
Full UK working-day overlap. Calls at whatever hour suits your team, and no waiting a day for an answer.
Can data stay in the UK?
Yes. We deploy into UK regions of your own cloud account, and models can run there as well, so personal data stays in the UK.
Can you work with FCA-regulated firms?
Yes. That means following your outsourcing and operational resilience requirements, keeping audit trails and making sure AI outcomes can be monitored and explained, all documented for your compliance team.
We already have hardware and a model running. Is that a problem?
It is the ideal starting point. Existing work is classified during the assessment as preserved unchanged, preserved with changes, or replaced, with reasons, and nothing is replaced without your written agreement.
Can it be fully air gapped?
Yes, including model and dependency mirroring, offline updates and local evaluation, with no outbound network access at all.
Who holds the accounts?
You do, throughout. Cloud accounts are created and held by you, our access is named and limited-privilege, and it is removed at handover with written confirmation.
Private LLM Infrastructure
Self-hosted LLM deployment on hardware you own. vLLM serving, private networking, validated output.
