ChatGPT pricing questions
ChatGPT Free costs nothing. Go is £7 a month, Plus £20 and Pro from £89, all including VAT. Business is £18 a seat a month, or £15 paid yearly, for 2 to 200 people, and premium seats are £90, or £75 paid yearly. Business prices exclude VAT. Enterprise is priced on request.
It depends on the plan. OpenAI's checkout data marks Go, Plus and Pro as including 20% VAT, so Plus is £20 a month all in, and Business as excluding it, so VAT is added to £18 a seat. This page shows each plan the same way. OpenAI's billing help says a business that enters its VAT ID at checkout is exempted from VAT on Business.
Yes, for web subscriptions: OpenAI's billing help lists GBP for the United Kingdom. Existing subscribers keep their original billing currency, so moving to GBP means cancelling and subscribing again once the period ends. The API is billed in US dollars only.
Plus and Pro are for one person each. Pro comes in three tiers, Pro 100, Pro 200 and Pro 500, with more usage at each, and only Pro 500 includes Ultrafast. Business is a shared workspace for 2 to 200 people with company context and admin, in standard seats or premium seats with 5 times the usage and no 5-hour limit.
Only on Business. A standard seat is £15 a month paid yearly against £18 paid monthly, about 17% less, and a premium seat £75 against £90. Go, Plus and Pro are monthly only, with no annual or multi-month prepay.
No. The OpenAI API is billed separately on platform.openai.com, in US dollars, from prepaid credits with a minimum top-up of US$5 that expire after a year. GPT-6.1 Sol is US$2 per million input tokens and US$10 per million output tokens; GPT-6 Astra is US$10 and US$50; GPT-6 Luna is US$0.10 and US$0.50.
ChatGPT pricing sources and methodology
From OpenAI's public checkout pricing configuration for the United Kingdom, read on 18 October 2026, with OpenAI's help centre for plan rules. Its US figures match chatgpt.com/pricing and openai.com/business/pricing as shown from a US connection, which is the check that it holds the live prices. The UK App Store listing was checked against it: its prices for Go, Plus and the Pro tiers round to the same whole amounts as the prices here.
OpenAI's checkout data marks Go, Plus and Pro as including 20% VAT and Business as excluding it. Prices here follow it: the personal plans including VAT, as buyers see them, and Business seats excluding VAT. OpenAI's billing help says a business that enters its VAT ID at checkout is exempted from VAT on Business.
Estimates from list prices: Go, Plus and Pro including VAT, Business excluding it. Free, Go, Plus and Pro serve one person each, so two or more people are priced on Business. Premium seats are priced when entered. Extra usage credits are added at cost, because OpenAI does not publish a credit's price. API tokens are priced on the chosen model from Ensurva's AI price guides, in US dollars converted to GBP at the European Central Bank reference rate (1 USD = 0.74989 GBP, 16 October 2026); no ChatGPT plan includes API credits. Company size assumes every employee gets a standard seat and no extra usage. Enterprise is not priced.
ChatGPT Pro is listed once, at £89 including VAT, the Pro 100 tier. Pro 200 at £200 and Pro 500 at £445 are listed as additional costs.
The API table comes from the same data as Ensurva's AI price guides, read from OpenAI's own pricing pages, in US dollars per million tokens.
No dated GBP prices have been collected for the United Kingdom, so the chart shows the OpenAI API's prices only.
Drawn from how OpenAI charges, not from records of negotiated deals.
No public comments from UK buyers have been collected yet, so the section is not shown.
Checked monthly against OpenAI's own pages.
The calculator's By use case tab puts each person on a seat that suits how heavily their role uses AI. Software developers use it most, about 15% of their working hours against about 6% across all workers (Federal Reserve Bank of St. Louis, 2026), so they get the heavier seat where the plan has one. Content, support and finance staff fit a standard seat, and general office staff use AI least. Each automated job is priced at a typical size, about 100 tokens to 75 words: a support reply reads about 1,100 words and writes 200, and a contract summary reads 10,000 and writes 750. Decision jobs read the record and give a short typed answer: about 600 words to route a support ticket, 4,500 to check a document against a policy. Those sizes are Ensurva's own estimates. A model that writes no text, such as Jev, is priced on decision jobs only. Jobs are priced as API use on the vendor's default model, less any API credits the plan includes.
