The phrase “connect UK bank account with ChatGPT” can hide an important regional difference.
OpenAI introduced Finances in ChatGPT as a US rollout, so UK users should not expect the @Finances flow to accept a UK bank today. The current direct route is a BankSync custom MCP app in a ChatGPT Business or Enterprise/Edu workspace where the admin has enabled developer mode and app creation.
UK institutions connect to BankSync through Salt Edge under UK Open Banking. Access is read-only, account-scoped and revocable. Personal and business entities can appear separately, and consent commonly needs reconfirming on a rolling cycle, often around 90 days.
Never paste an online-banking password, one-time code or full account number into a ChatGPT conversation. Authentication belongs in the bank’s UK Open Banking consent pages, and ChatGPT should receive only the data made available through the selected connection.
Current options for UK users
| Feature | Finances in ChatGPT | BankSync MCP | Spreadsheet or file |
|---|---|---|---|
| Current route | Not available for this country | Direct in eligible workspaces | Available for controlled exports |
| Best use | Wait for regional rollout | BankSync data and workflows in ChatGPT | One-off or individual-plan analysis |
| Freshness | n/a | Retrieved through BankSync tools | Fixed at export time |
| Admin needed | n/a | Yes, for workspace app setup | Usually no |
| Technical setup | None | Create and authorise a custom MCP app | Export or upload the dataset |
What you can connect
Depending on the institution and route, ChatGPT can work with supported current, savings and supported credit accounts. The institution controls which products, fields and history it shares.
With BankSync MCP, ChatGPT can also use authorised tools for BankSync workspaces, feeds, integrations and sync jobs. BankSync MCP requires the Standard plan or above.
The bank connection itself remains read-only. It cannot transfer funds, pay bills, alter bank settings or place trades. BankSync configuration tools may still create or change a feed when the app and workspace deliberately grant that permission.
Connect a UK bank account to ChatGPT
Connect the financial institution in BankSync
Open Banks, search the exact UK institution, complete the bank’s UK Open Banking consent pages and select only the accounts needed.
Confirm the BankSync connection
Check that the bank appears as an active card with the expected accounts attached. Resolve any re-authentication state first.
Confirm ChatGPT workspace eligibility
OpenAI’s current help says full custom MCP apps and developer mode are available on Business and Enterprise/Edu on ChatGPT web, subject to admin controls.
Create the BankSync custom app
In ChatGPT settings or workspace administration, open Apps → Create and enter https://mcp.banksync.io as the remote MCP endpoint.
Authenticate, scan and restrict tools
Complete BankSync authorisation, let ChatGPT scan the tools and limit app access or actions to the users and capabilities the workflow requires.
Authorise the correct BankSync workspace
Keep personal, business and client entities separate. Do not authorise a broader workspace merely to simplify setup.
Verify the connection
Ask ChatGPT to list every accessible UK account, type and currency. Compare the response with the BankSync Banks page.
Common UK setup problems
A failed AI query is often a bank-connection or eligibility problem. Check the underlying institution, account selection, consent state and workspace role before repeatedly removing and re-adding the app.
Troubleshooting UK connections
| Issue | Likely cause | Resolution |
|---|---|---|
| @Finances is missing or rejects the region | The native product is not currently offered as a UK bank connection. | Use an eligible BankSync MCP workspace or a controlled spreadsheet/file workflow. |
| Wrong entity connected | Personal and business banking may be listed separately. | Choose the exact UK entity that holds the accounts. |
| Consent is expiring | The Open Banking authorisation is approaching reconfirmation. | Use Renew now and approve access again on the bank’s page. |
| Account drops after renewal | It was not re-selected during the new consent. | Renew again and tick every account that should remain shared. |
| Custom app cannot be created | Developer mode or Apps → Create is not enabled for the workspace or user. | Ask the Business or Enterprise/Edu admin/owner to enable and vet it. |
Start with the source connection, then verify ChatGPT app access.
Ask questions that expose missing data
Start with a bounded request. Require ChatGPT to state the accounts, currencies, date range and source used. For categories or recurring patterns, ask for the underlying transactions.
Do not use a conversational total as a substitute for an institution statement, tax record or professional financial advice.
Useful ChatGPT prompts for UK accounts
| Goal | Prompt | Check |
|---|---|---|
| Cash position | Show GBP balances by connected UK account, with current and available values separated. | Check every intended current and savings account. |
| Direct debits | Identify repeating direct-debit patterns and show the supporting transactions. | Verify merchant and cadence. |
| Monthly spending | Summarise non-transfer outflows for the last complete month. | Exclude transfers and card repayments. |
| Business cash flow | Compare inflows and outflows for the authorised UK business workspace only. | Ensure personal accounts are not included. |
| Connection health | List UK BankSync connections or jobs that need attention. | Confirm against the BankSync dashboard. |
The exact result depends on the connected products and fields supplied by the institution.
Least privilege
Connect only the accounts and BankSync tools needed for the current workflow.
Visible assumptions
Require sources, date ranges, currencies and exclusions in every important answer.
Entity separation
Keep personal, business and client data in distinct BankSync workspaces and ChatGPT access groups.
Disconnect both layers
Remove the ChatGPT app and revoke the underlying BankSync or bank consent separately when finished.
Security checklist
- Enable multi-factor authentication for ChatGPT, BankSync and the institution.
- Keep bank credentials inside the provider or bank-hosted flow.
- Authorise the minimum account set.
- Use separate BankSync workspaces for separate legal entities or clients.
- Inspect ChatGPT’s app permissions and action controls.
- Review data controls that apply to the ChatGPT plan.
- Verify important figures against the institution.
- Delete financial conversations separately where appropriate.

The bottom line
The native Finances route is not currently available for this region. An eligible ChatGPT workspace can use BankSync MCP; individual users can use a controlled spreadsheet or file until regional or plan availability expands.
Whichever route you choose, keep authentication outside the conversation, grant the minimum access and verify the first result against the source.
