v0.6.3

What's New

Electric & Gas Bill History via Business Portal Silent SSO

Two new typed client methods for retrieving per-billing-period bill history from the National Grid business portal (accountmanager.nationalgrid.com):

• get_electric_bill_history(account_number, customer_number) → list[ElectricBillRecord]
• get_gas_bill_history(account_number, customer_number) → list[GasBillRecord]

Both methods return itemised charges per billing cycle including utility/supplier charge breakdown and (for electric) demand fields. customer_number is available from get_billing_account().

Authentication: The business portal uses a separate OAuth client registration in the same B2C tenant. After the consumer portal login establishes a session, a prompt=none silent SSO request automatically acquires a business portal id_token with the correct audience — no second login prompt. The business token is cached and refreshed independently of the consumer access token.

New example script:

uv run python examples/bill-history.py \
  --username user@example.com --password secret

Bug Fix: TimeoutError now caught in OIDC helpers

asyncio.TimeoutError (Python 3.11+ builtin TimeoutError) is not a subclass of aiohttp.ClientError and could previously escape uncaught from the _get_auth_silent and _fetch helpers. Both now catch (aiohttp.ClientError, TimeoutError) and normalise to CannotConnectError.
