Evals-first generative AI for the United Kingdom — UK data residency, guardrails, audit-grade.
Generative AI is a stack, not a prompt — and the UK organisations actually shipping past the demo are the ones who treat retrieval, tool-use, evaluation, safety, and observability as load-bearing. We write the eval harness before the prompt. We pin LLM inference to a UK or EU region when UK GDPR or your DPO requires it. We run the entire build inside your AWS London (eu-west-2) or Azure UK South account whenever your security team prefers to own the runtime. Across 50+ production AI systems and 12 industries, our generative AI portfolio includes a customer-support deflection agent at 68% L1 resolution on a 2M-subscriber telco, an outbound voice agent saving 1,400 staff-hours a month on a regulated European insurance workflow, and a citation-grounded medical-inquiry RAG at 98.4% citation accuracy with zero policy-violating answers in 90 days of production.
The UK buyers we typically work with — CTOs at Series A and B London SaaS scale-ups, Heads of Engineering at FCA-supervised fintechs, product directors at UK healthtech and govtech operators — share a starting point. They have already paid a London AI consultancy for a discovery phase, a deck, and a prompt-engineering proof-of-concept that ran beautifully on the demo dataset and disintegrated on the first slice of production traffic. We exist for the build that follows. We are model-agnostic on principle: Claude Sonnet and Opus on Anthropic, GPT-4o and the o-series on Microsoft Azure OpenAI Service in UK South, Llama 3 70B or 8B self-hosted on vLLM inside your VPC for clients who refuse third-party inference. We pick what hits your eval bar inside your latency and cost budget — not what is trending this week. Prompt-injection defence, PII redaction, jailbreak detection, and a continuous eval suite that runs on every prompt change are scoped in week one, not added as a phase-two rescue project.
Time-zone overlap with the UK is the strongest in our portfolio. Indian Standard Time is GMT+5:30, which gives roughly four to five hours of native daily overlap with UK business hours — our 1:30pm IST is your 8am GMT, our 6:30pm IST is your 1pm GMT. Daily standups, twice-weekly demos with eval-run numbers, and ad-hoc debugging all land inside UK business hours. Six-week target from kickoff to a working v1, fixed-price scope written in 72 hours, overrun cost on us if we miss for reasons on our side. UK GDPR-aligned DPAs are signed before any personal data is processed, and DPIAs are run for any generative system processing personal data at scale. The cost difference versus a London AI consultancy lands roughly 30 to 50 percent lower on senior rates — useful, but the headline is the engineer on your kickoff call writes your prompts, your evals, and your code.

Production work, not prototypes.
LLM applications & copilots
Production LLM applications optimised for UK data residency. Streaming UIs, multimodal inputs, and domain-grounded responses. Claude, GPT-4o, or self-hosted Llama 3 picked per eval bar and latency budget — not vendor loyalty.
ExploreRAG systems for UK regulated use
Hybrid retrieval (BM25 + vectors) over your private corpus with required citations and a refusal layer when context is missing. 98.4% citation accuracy in a regulated reference deployment.
ExploreAgentic workflows
Multi-step agents with typed tool calls, memory, refusal layers, and audit logs — embedded inside your existing SaaS product, FCA-regulated platform, or internal tool. Bounded recursion, not autonomy theatre.
ExploreSelf-hosted Llama 3 on vLLM
Llama 3 70B or 8B on vLLM inside your AWS London or Azure UK South VPC for clients with strict data-egress policies. Zero customer data leaves your cloud. Reproducible LoRA fine-tunes with versioned datasets and weights.
ExploreEvals, guardrails & observability
Prompt-injection defence, PII redaction, jailbreak detection, and a continuous eval suite that runs on every prompt change. Cost and latency telemetry from day one — not bolted on after the first prod incident.
ExploreVoice & multimodal
Sub-second STT-to-TTS pipelines on Twilio, LiveKit, or Deepgram with British English voices. Image, document, and video input where it earns its keep — not where it pads the brief.

Questions teams actually ask.
How does the time-zone overlap work for UK clients on a generative AI build?
Strong. India Standard Time is GMT+5:30, which gives roughly four to five hours of native daily overlap with UK business hours — our 1:30pm IST is your 8am GMT, our 6:30pm IST is your 1pm GMT. Daily standups, twice-weekly demos with eval-run numbers, and ad-hoc debugging on a regression all land inside UK business hours without late-night calls on either side. Written async updates with the previous night's eval results go out daily before your standup, so you walk into the day already knowing what regressed.
Is generative AI built by Aiinfox UK GDPR and ICO aligned?
Yes. Engagement defaults align with UK GDPR, the Data Protection Act 2018, and ICO published guidance on AI and automated decision-making. Every model and tool call is audit-logged with input, output, prompt version, and operator identity — exportable for ICO inspection. A Data Protection Impact Assessment (DPIA) is run for any system processing personal data at scale or producing legal or similarly significant effects on a data subject. We also track the EU AI Act and the UK government's pro-innovation framing on AI regulation so the system is structurally ready for the controls that land next.
Does Aiinfox sign UK-specific DPAs and SCCs?
Yes. We sign UK GDPR-aligned Data Processing Agreements covering the Article 28 processor obligations: processing only on documented instructions, confidentiality of personnel, security of processing, sub-processor management, data subject rights assistance, breach notification, and deletion or return of personal data at the end of the engagement. International transfers of personal data are covered by the UK International Data Transfer Agreement (IDTA) or the EU Standard Contractual Clauses with the UK addendum. We will work from your DPA template or provide ours.
Can you deploy generative AI inside our AWS London or Azure UK South account?
Yes — that is the most common UK deployment pattern we run. We work inside your AWS, Azure, or GCP account in any UK or EU region you specify, using your IAM, your VPC, and your customer-managed encryption keys. For inference, we route to UK or EU endpoints on Claude (Anthropic) and GPT-4o (Microsoft Azure OpenAI Service in UK South), or we self-host Llama 3 70B or 8B on vLLM inside your VPC if your team requires zero third-party inference. We do not silently route UK personal data through non-UK endpoints.
Do you work under an MSA plus per-project SOWs, or one-off SOWs?
Either. Most repeat UK clients move to a Master Services Agreement after the first engagement so subsequent generative AI builds, fine-tuning work, evaluation work, and on-call retainers ship under a per-project Statement of Work without renegotiating the umbrella terms. For a first engagement, a standalone SOW with the DPA appended is the standard pattern. Legal turnaround is usually one to two weeks depending on your DPO's review cadence.
Why evals-first rather than prompt-engineering iteration?
Because prompt-engineering without an eval harness is opinion-driven development. You change the prompt, the demo looks better on the three queries you tested, you ship, and the system regresses on the four hundred queries you did not test. The eval harness — agreed against your acceptance criteria in week one — gates every prompt change against quantitative quality, refusal rate, hallucination rate, cost, and latency before the change reaches production. It is the single largest reason our generative builds hold up past launch where consultancy proofs-of-concept disintegrate.
How does cost compare to a London AI consultancy?
Most v1 generative AI engagements at Aiinfox land between £20,000 and £100,000 fixed-price for a focused build — an LLM copilot, a RAG system, an agentic workflow, or a voice pipeline. Larger multi-quarter engagements with fine-tuning, custom evals, and FCA-aware compliance work typically reach £150,000 to £250,000. The cost difference versus a London AI consultancy lands roughly 30 to 50 percent lower on senior rates — but the headline is the engineer on your kickoff call writes your code, not a junior at the consultancy's offshore arm.
Can you take over a stalled generative AI build from a London consultancy?
Yes — takeover audits are routine. Step one is reading the code, the prompts, the eval results (if any exist), the guardrails, and the cost telemetry. Step two is shipping the smallest valuable change — usually an eval harness, a refusal layer, or a guardrail upgrade — to prove we understand the system. Step three is the longer-term plan: incremental stabilisation, a parallel rebuild, or shutting it down and starting over. Most takeovers we see did not need a full rewrite; they needed evals, guardrails, observability, and a senior engineer on the build.
