What a ChatGPT enterprise implementation engagement covers

Engagements run in three phases. The first 30 minutes are free; we move to paid work only when both sides see a credible fit.

Phase 1: Scoping

Requirements analysis, data audit, and the architecture decisions that shape everything downstream. Outputs:

  • Prioritised use-case shortlist with hard versus soft benefit separation.
  • Data audit covering availability, quality, sensitivity, and classification.
  • UK data residency decision: ChatGPT Enterprise UK region, API via a UK-compliant cloud, or hybrid.
  • Risk and compliance assessment against UK GDPR, the EU AI Act, and sector regulators (FCA, SRA, ICAEW, MHRA).
  • Itemised proposal with timeline, scope, and commercial terms.

Phase 2: Build

Technical implementation. Scope varies; the recurring building blocks are:

  • OpenAI API integration or ChatGPT Enterprise deployment, including SSO, role-based access, and audit logging.
  • Workflow design: where ChatGPT fits in each user's day, what it replaces, and the handover points to humans.
  • System integrations into CRM, ERP, document repositories, Microsoft 365, Google Workspace, and case or matter management systems.
  • Prompt and tool design validated against real tasks, with evaluation harnesses for pass-fail rates and red-team checks on prompt injection and data leakage.
  • Staff training materials covering role-specific workflows, not generic prompt engineering.

Phase 3: Rollout

The phase most ChatGPT rollouts skip. Outputs:

  • Change management plan: communications, training waves, early-adopter cohorts, and resistance handling.
  • Written acceptable use policy aligned to UK GDPR and the EU AI Act.
  • Adoption monitoring: weekly active users, task coverage, time-saved sampling, and a feedback loop into the prompt and tool layer.
  • Ongoing optimisation as OpenAI releases new models and features, and as your own workflows evolve.

UK data residency: ChatGPT Enterprise, OpenAI API, and hybrid

Data residency is the question that gates most regulated-sector ChatGPT rollouts in the UK. The landscape changed materially in late 2025 and continues to move.

  • ChatGPT Enterprise UK data residency. OpenAI launched a UK data residency region for ChatGPT Enterprise in October 2025. Customer data, conversations, and prompts can be stored in the UK at rest, which materially eases UK GDPR and sector regulator conversations.
  • Public-sector adoption signal. The Ministry of Justice deployed ChatGPT Enterprise to 2,500 staff, a reference datapoint for UK public-sector tenders evaluating the platform.
  • UK reseller channel. PwC became the first ChatGPT Enterprise reseller in the UK, signalling enterprise channel maturity around the product.
  • Regulated sector relevance. For FCA-regulated financial services firms, SRA-regulated legal practices, healthcare providers, and public-sector buyers, UK data residency is often a procurement gate rather than a preference. The October 2025 region removes a previous blocker for many of these buyers.

The AI Consultancy helps clients choose between ChatGPT Enterprise, an API-only architecture, and hybrid models based on their data classification, integration requirements, and regulatory overlay. For light internal-productivity use with no sensitive data, Team or API-only is often the right answer. For organisations handling regulated client data, ChatGPT Enterprise on the UK residency region is usually the cleaner path. Hybrid architectures sit between the two: ChatGPT Enterprise for general-purpose staff use, API integrations for the specific workflows that need bespoke control.

ChatGPT consultant UK pricing

Every engagement is scoped after a free initial consultation. The ranges below are indicative, not a price list. We issue a written, itemised proposal after the scoping conversation.

  • Simple ChatGPT API integrations: from approximately £3,000. Single workflow, light system integration, no compliance overlay.
  • Mid-complexity integrations: £8,000 to £25,000. CRM integration, retrieval-augmented generation (RAG) pipelines, or multi-department rollouts.
  • Enterprise multi-system integrations: £25,000 to £80,000 or more. CRM, ERP, document workflows, SSO, audit logging, and compliance design for regulated sectors.
  • Free initial consultation: all engagements start with a 30-minute scoping call at no cost. We move to paid work only when both sides see a credible fit.

Our depth on the OpenAI side is matched by depth across the wider AI ecosystem. The AI Consultancy is an Anthropic Consulting Partner, AWS certified, and Google Cloud certified. That matters for ChatGPT engagements because the right answer is often a multi-model architecture: ChatGPT for some workloads, Claude or Gemini for others, with the routing decisions made on fit rather than vendor loyalty. For a structured comparison of the two leading enterprise options, see our guide to comparing Claude and ChatGPT for UK businesses.

Frequently asked questions

What does a ChatGPT implementation consultant do?+
A ChatGPT implementation consultant scopes your use cases, designs UK GDPR-compliant and data-residency-appropriate architecture, integrates ChatGPT with your existing business systems, trains your team, and establishes governance for ongoing operation. The engagement covers discovery, build, deployment, and handover.
How much does ChatGPT implementation cost for a UK business?+
A simple API integration or internal chatbot typically starts from £3,000. Mid-complexity projects involving CRM integration, retrieval-augmented generation (RAG) pipelines, or multi-department rollouts range from £8,000 to £25,000. Enterprise multi-system deployments with custom data residency and governance documentation run £25,000 to £80,000 or more.
How long does ChatGPT implementation take?+
A scoping and discovery engagement typically takes two to four weeks. A complete build and deployment takes six to twelve weeks depending on integration complexity, data preparation requirements, and the number of departments involved.
What are the UK GDPR requirements for deploying ChatGPT in a business?+
UK businesses must complete a Data Protection Impact Assessment (DPIA) before processing personal data through ChatGPT. ChatGPT Enterprise supports data residency in Azure UK South and AWS EU (London). Input and output data is not used for model training under the Enterprise agreement by default. We advise on ICO compliance, DPA 2018 obligations, and sector-specific requirements under FCA, SRA, and NHS frameworks.
Does ChatGPT Enterprise support UK data residency?+
Yes. ChatGPT Enterprise can be configured to use Microsoft Azure UK South or AWS EU (London) for data residency, satisfying UK GDPR and ICO requirements. Zero data retention is available under Enterprise agreements: data is not stored or used to train models.
What is the difference between ChatGPT Business and ChatGPT Enterprise for UK organisations?+
ChatGPT Business adds admin controls and a data processing agreement, making it suitable for teams handling non-sensitive internal tasks. ChatGPT Enterprise adds SSO, audit logs, advanced security, dedicated infrastructure, API access, and custom data residency options, the appropriate tier for regulated UK businesses handling client or patient data.
Is ChatGPT Enterprise suitable for SMEs?+
It can be, but is rarely the cheapest option. ChatGPT Enterprise is priced for organisations needing UK data residency, SAML SSO, admin controls, and unlimited use of premium models. SMEs handling sensitive client data often justify it. For lighter use cases without those requirements, ChatGPT Team or an API integration is usually more economical.
What is the difference between a ChatGPT API integration and a ChatGPT Enterprise deployment?+
An API integration embeds ChatGPT into your own application or workflow via OpenAI's API; data flows are programmatic and you control the user interface. A ChatGPT Enterprise deployment is the OpenAI-managed product with admin controls, SSO, and audit logging. Many organisations end up running both: Enterprise for general productivity and the API for specific embedded use cases.
What does post-rollout support look like?+
Post-rollout support covers adoption monitoring, prompt and integration refinement, new use-case onboarding, and updates as OpenAI releases new models or features. We typically run a 4 to 8 week intensive support phase after go-live to resolve adoption issues before they entrench, followed by an optional ongoing retainer for organisations needing continued operational support.
How does The AI Consultancy differ from generic AI training providers?+
Generic training providers teach prompt engineering and basic ChatGPT use. The AI Consultancy delivers the full implementation: technical integration, data architecture, compliance design, and the change management that drives adoption. As a multi-vendor partner (Anthropic Consulting Partner, AWS certified, Google Cloud certified), we are not tied to a single model and recommend the right fit for each use case.
