Claude Integration in London
Integrating Anthropic's Claude models into London products and internal tools. Claude is frequently chosen for long-document work and for tasks where following instructions precisely matters more than fluency, and the model tier you pick has a larger effect on cost than most teams expect.
Why this comes up
The problem
An AI feature is planned but nobody has decided which model, what it will cost per request, or how the output gets checked before a customer sees it.
What you get
What we deliver
- Integration through the Anthropic API, with the model tier matched to the task
- Long-document handling that uses the large context window rather than fighting it
- Structured output where the response feeds another system rather than a person
- Tool use, so the model can call your functions instead of guessing at data
- Prompt caching where the same context repeats, which changes the cost profile materially
- Evaluation against your own examples before it goes anywhere near production

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Claude Integration in London — common questions
- Which Claude model should we use?
- Anthropic publishes tiers at different capability and price points — the Opus tier for the hardest reasoning, Sonnet as the balanced default, Haiku for high-volume simple work. Start with the smallest that passes your evaluation; the cost difference across tiers is large and the quality difference is task-specific.
- What is Claude good at compared with alternatives?
- In practice it is often preferred for long-document analysis and for tasks needing careful instruction-following over a large context. That said, relative strengths shift with each release, so the useful answer comes from testing both on your actual task rather than from comparison articles.
- How does prompt caching affect cost?
- When a large fixed context is sent repeatedly — a policy document, a long system prompt — caching it means you are not billed at full rate for the same tokens every request. For high-volume applications with a stable prefix it is one of the larger cost levers available.
- Can we run it through AWS rather than direct?
- Yes — Claude is available through Amazon Bedrock and other cloud platforms, which some organisations prefer for procurement, billing or data-residency reasons. Feature availability can lag the direct API slightly, so it is worth checking against what you actually need.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
