The short answer.

For a UK business where two or more people use ChatGPT for work, ChatGPT Business is the plan to use. It’s OpenAI’s shared workspace for teams (it was called ChatGPT Team until August 2025), OpenAI doesn’t train its models on Business data by default, and the business, not each employee, controls who has access. Use it to draft, summarise and tidy office writing, with a person reading everything before it goes to a customer. Keep out anything you wouldn’t email to a stranger. When the same copy-and-paste job happens many times a day, connecting AI to your own systems usually does it better.

Which ChatGPT plan a business needs.

OpenAI’s plans as its own pages describe them on 3 November 2026. They change often, so check before you buy.

ChatGPT plans compared for business use
Question	Free, Go, Plus and Pro	Business	Enterprise
Made for	Individuals. OpenAI says these plans are designed to be used by one person.	Teams. Self-serve, with a minimum of two seats.	Larger or regulated organisations, arranged through OpenAI’s sales team.
Your chats used to train OpenAI’s models	Yes, unless each person opts out in their own settings.	No, by default.	No, by default.
Who controls the accounts	Each person, on their own account. The business can’t see or remove what’s in it.	The business: one workspace with owner, admin and member roles, two-factor sign-in, single sign-on and basic usage figures.	As Business, plus automatic adding and removing of users from your directory, custom roles and spend controls.
Terms	OpenAI’s consumer terms.	OpenAI’s business terms, with a data processing addendum available.	A contract through OpenAI’s sales team, with a data processing addendum.
Data stored in the UK	Not offered.	Not listed for Business.	Available to eligible customers.
How it’s paid for	Per person, by card, apart from Free.	Per seat, monthly or annually. Standard seats, or Premium seats with higher usage limits, mixed as you like.	Annual, by quote, with invoicing available.

For most owner-managed firms with two or more people using it at work, Business is the sensible plan. Enterprise answers a specific need, such as a contract that requires UK data storage.
ChatGPT Business is what OpenAI called ChatGPT Team until it renamed the plan on 29 August 2025.
The API, which developers use to build AI into other software, is separate and billed separately. Business doesn’t include it.
OpenAI lists prices per user per month on its pricing page. We don’t repeat them here because they change.

Is it safe? Data and privacy basics.

Not legal advice

UK GDPR applies to ChatGPT like any other software. If staff paste in a customer’s name, address or phone number, or a complaint about a named tenant, your business is responsible for that personal data, whichever plan you use.

Personal accounts are the main risk. When staff use their own Free or Plus accounts for work, the business can’t see, manage or delete what’s been pasted in, and by default those chats can be used to train OpenAI’s models unless each person opts out. Moving work onto a Business workspace moves that decision from each person’s settings page to the business.

What OpenAI says about Business and Enterprise. It doesn’t train on your data by default, encrypts it at rest and in transit, and will sign a data processing addendum. It says its practices align with SOC 2 Type 2 and ISO/IEC 27001. Storage in the UK is offered to eligible Enterprise customers, not on Business.

How long chats are kept. Saved chats stay until someone deletes them. Deleted chats are scheduled for removal from OpenAI’s systems within 30 days. Temporary chats don’t appear in history, but OpenAI may keep a copy for up to 30 days for safety.

Connected apps see what the person sees. If you connect shared drives, ChatGPT can search whatever the person using it has access to. If your folder permissions are loose, tidy them first.

If ChatGPT will handle customer personal data, record OpenAI as a processor and mention it in your privacy notice. The ICO’s guidance on AI is the place to start, and take advice if you handle health or other sensitive data.

Five rules for the office.

Put these on one page and give it to everyone with a seat.

Use a Business workspace for work, not personal accounts.
Don’t paste in bank details, health information, passwords or staff matters.
Leave out names and addresses you don’t need: “the customer at the Leeds job” works as well.
A person reads everything before it goes to a customer, supplier or regulator.
It never decides prices, safety or legal points on its own.

Where it helps in the office.

Illustrative examples for an office that runs work on site or on the road. Swap in your own details, and remove names you don’t need.

Replies from rough notes
The office knows what to say but not how to word it. ChatGPT turns three scribbled lines into a clear, polite reply in a few seconds. Check dates and times against your diary before sending.
Example promptYou write for a commercial cleaning company. Turn these notes into a reply to a customer who asked to move Tuesday’s clean to Thursday. Under 80 words, British English, friendly but brief. Don’t promise an arrival time. Notes: [paste]
Long email threads, before a call
A thread with a customer or a main contractor has run to twenty emails. A summary gives whoever picks it up the state of play without reading all of it. Read the original before you quote anything back.
Example promptSummarise this email thread in five bullet points: what the customer asked for, what we agreed, what’s still open and who owes the next reply. Copy dates and amounts exactly as written. Thread: [paste, with names removed]
Engineers’ notes into a customer report
Site notes are written for colleagues, not customers. ChatGPT can turn them into a short report in plain English, but it will fill gaps unless you tell it not to.
Example promptTurn these engineer’s notes into a short job report for the customer: work done, parts used, anything that needs a return visit. Don’t add anything that isn’t in the notes. Mark anything unclear as [CHECK]. Notes: [paste]
First drafts of documents
A policy, a job advert, a handbook section or a method statement template is quicker to edit than to start. Treat it as a first draft for someone who knows the subject to correct, never as the finished thing.
Example promptDraft a first version of a lone-working policy for a property maintenance firm with 15 staff, most of them out on jobs. Plain headings, short sentences. Mark anything that needs checking by a health and safety adviser.
Making sense of a spreadsheet
Paid plans can analyse an uploaded spreadsheet and chart it. Export only the columns you need, without customer names, and spot-check the figures it gives you against the sheet.
Example promptThis is last month’s job list: date, postcode district, job type, first-time fix (yes/no). Which job types have the lowest first-time fix rate? Show a table, then explain in three sentences how you worked it out.
Getting the tone right on a complaint
When a reply has been rewritten three times and still sounds defensive, ChatGPT is good at a calmer version. Keep the facts yours, and leave any offer for a person to decide.
Example promptRewrite this reply to a complaint about a missed appointment so it’s calm, specific and apologetic. Keep every fact exactly as I’ve written it. Don’t add any offer or refund; leave [OFFER] where one might go. Draft: [paste]

How to write a prompt that works.

Most poor answers come from too little to go on. Five habits fix most of it.

1Say who it’s writing as and who for: “You write for a removals company. This goes to a customer.”
2Give it the facts. It only knows what you paste in, so give it the notes, the dates and the detail.
3Set the shape: length, format, British English, and an example of one you liked.
4Say what not to do: don’t invent details, don’t promise times, mark gaps as [CHECK].
5Save what works. Put the instructions and an example in a Project, or a custom GPT the whole workspace can use, so nobody retypes it.

What it can’t do.

Knowing the limits is most of using it safely.

It makes things up
It writes confidently even when it’s wrong: a regulation, a date, a figure, a part number. Check anything factual before you rely on it.
It only knows what you give it
It doesn’t know your jobs, prices, diary or customers unless someone pastes them in or connects a source, and then it only knows what that source holds.
It isn’t your system
A chat can draft a reply, but it doesn’t update your job record, raise the invoice or book the engineer. Somebody still copies the result across.
It changes
Models, limits and features change every few months, and the same prompt can give different answers on different days. What worked in spring needs re-testing.

When an integration beats copy-paste.

ChatGPT works on whatever someone pastes into it. An integration connects the same kind of AI to your own systems, so the copying stops.

Using ChatGPT by copy and paste compared with a built integration
Question	ChatGPT, copy and paste	A built integration
Who starts it	A person opens ChatGPT and pastes something in.	It starts on its own: a new enquiry, a finished job, a form.
Where the facts come from	Whatever the person copies in, so it varies.	Your job system, inbox or accounts, read directly.
Where the result goes	Back into your systems by hand.	Into the right record, ready for a person to approve.
Consistency	Depends on who writes the prompt.	The same rules and wording every time.
A record of what was sent	Scattered across people’s chats.	Kept with the job, with who approved it.
How the cost works	A subscription per seat, paid to OpenAI.	Scoped and priced as a piece of work, then any running costs, set out before you commit.

Copy-paste is fine when

The task is occasional, or different every time
One or two people do it
The facts are in someone’s head or notes, not a system
A slightly different answer each time doesn’t matter

Build it properly when

The same task happens many times a day or week
Someone copies details out of one system and back into another
The result has to land in a job, a quote or the diary
You need the same rules for everyone, and a record of what was sent

AI integration AI assistants and agents

Rolling it out in a small firm.

The subscription is the easy part. Whether it helps comes down to a few decisions. If you’d like a second opinion on what to build, that’s what a Fit check is for.

1Move work onto one Business workspace, and ask staff to stop using personal accounts for work.
2Write a one-page policy: what can go in, what can’t, and that a person checks anything sent out.
3Pick two or three tasks the office does every week, not twenty.
4Set each one up as a Project with your instructions and a good example.
5Try it with two or three people for a few weeks, and note what they still copy and paste.
6Then decide: keep it as it is, drop what doesn’t help, or build the repetitive part properly.

ChatGPT for business questions.

About ChatGPT at work. Questions about us are in the full list.

What is ChatGPT Business?

ChatGPT Business is OpenAI’s self-serve plan for teams. It gives a business one shared workspace with central billing, admin controls for users and roles, single sign-on, and access to ChatGPT’s features, including Projects, custom GPTs, connected apps and deep research. It needs at least two seats.

Is ChatGPT Business the same as ChatGPT Team?

Yes. OpenAI renamed ChatGPT Team to ChatGPT Business on 29 August 2025. Seat types and prices have changed since, so check OpenAI’s pricing page for the current details.

Does OpenAI train on our business data?

Not by default on ChatGPT Business or Enterprise. OpenAI says it doesn’t use inputs or outputs from those plans to train its models. On the Free, Go, Plus and Pro plans, chats can be used for training unless each person opts out in their settings.

Can a UK business use ChatGPT under UK GDPR?

Yes, if you set it up and use it carefully. OpenAI offers a data processing addendum for business customers and doesn’t train on Business data by default, but your business stays responsible for what staff put in. Keep personal data out unless you need it, record OpenAI as a processor if you use it with customer data, and have a short staff policy. This isn’t legal advice; take advice if you handle sensitive data.

Is our data stored in the UK?

Not on ChatGPT Business. OpenAI offers storage in the UK, among other regions, to eligible ChatGPT Enterprise customers. If a customer contract or regulator requires UK data residency, that points to Enterprise or to a different set-up.

Can staff use their own ChatGPT accounts for work?

It’s best not to. On personal plans, the business can’t see, manage or delete what’s been pasted in, and chats can be used for training unless each person opts out. A Business workspace moves those decisions from each person’s settings to the business.

How much does ChatGPT Business cost?

It’s priced per seat, per month, billed monthly or annually, with a minimum of two seats. There are Standard seats and Premium seats with higher usage limits, and you can mix them. OpenAI lists current prices on its pricing page; we don’t repeat them because they change. Enterprise is priced by quote.

Does ChatGPT Business include the API?

No. OpenAI’s API, which developers use to build AI into other software, is a separate service billed separately. A ChatGPT Business subscription doesn’t include API usage.

Can ChatGPT connect to our job management software?

ChatGPT can connect to some common apps, such as file storage, so it can search what the person using it can already see. Most job management, accounts and CRM systems need a proper integration if you want AI to read jobs and put drafts back in the right record. That’s the kind of thing we build.

Can you set up ChatGPT for us?

If a ChatGPT Business workspace and a short policy are all you need, we’ll tell you on the free call, and that may be the end of it. Where the work needs more, such as connecting AI to your job system or inbox, that’s what we find, build and keep running. We’re independent of OpenAI.
