For a UK business, an AI service desk assistant brings two bills in two currencies. Claude seats, where a seat is one user's licence on a Claude plan, are billed directly by Anthropic in pounds. An agent's model usage is billed by Amazon Web Services in US dollars, on use. That usage is not capped unless you set a budget, so set one before go-live.
Data handling is the second check: you need processor terms with each supplier. Where a supplier outside the UK can access the data, the transfer needs cover. That means UK adequacy regulations where they apply, as for the EEA or a US supplier certified under the UK Extension to the EU-US Data Privacy Framework. Otherwise it means the IDTA (International Data Transfer Agreement) or the UK Addendum, together with a transfer risk assessment showing the protection is not materially lower than in the UK. Anthropic's commercial terms state that it does not train its models on content sent through its API. Usage through AWS is covered by AWS's own service terms; check both before go-live. The assistant runs on your company's own Anthropic or AWS account, with your keys, so access and usage records stay with you.
If the assistant talks to staff or customers in the EU, check the EU AI Act as well. Article 50 of the EU AI Act, which has applied since 2 August 2026, requires AI systems that talk to people to tell them they are dealing with an AI, unless that is obvious. That duty sits with the provider, which can include a business that puts the assistant into service under its own name. The UK has no equivalent AI Act. Article 50(5) requires the AI disclosure to be clear, distinguishable and accessible, and given at the first interaction at the latest. Where the Act applies, Article 4 also asks providers and deployers to take measures that support their staff's AI literacy. It sets no required level and no certificate.
Language and reach also affect cost. A second channel or a second language is priced separately on the Svennis service. A UK firm with offices abroad should list both before scoping the work.
