London is 4 h 30 min behind India
WhatsApp Business API for reaching London customers from India
A London mobile written as 07700 900456 looks exactly like an Indian one once the 0 goes. Store the number right, send on London's clock, and the rest is an approved template.
London
A 10:00–18:00 IST working day is 05:30–13:30 in London (on 21 October 2026; daylight saving moves it).
For India-based businesses with buyers, shoppers or applicants in London: why +44 numbers break in CRMs built for India and how to store them, what the UK–India trade deal means for your updates, when to send on London time, and what each message costs in rupees.

Fix a London number before your CRM breaks it
Most Indian forms and CRMs assume +91. Pick a London number below, written the ways customers write them, and see what an API needs instead.
A UK mobile written the domestic way, 07700 900456, is the trap. Strip the leading 0 and a rule written for India sees a ten-digit number starting with 7 and adds +91. The template then goes to an Indian number, or to nobody, and your London customer never hears from you.
The fix is upstream: ask for the country on the form, save every number as +44 followed by the digits without the 0, and reject a number with no country code instead of guessing. A London landline such as 020 7946 0991 cannot be guessed at all, which is the honest answer.
When your system sends through the developer API, it passes the number in that one format, so the cleaning has to happen before the send, in your own data.
Four ways to write a London number
E.164 is the one format phone APIs agree on: a +, the country code, then the number — no spaces, no leading 0.
Any format works: spaces, dashes, brackets, a 0 or 00 prefix.
- Digits
- 12
- For wa.me
- 917700900456
- Stripped 1 separator (spaces, dashes, dots, brackets).
- Dropped the leading 0 — a trunk prefix used only for domestic calls.
- Assumed India (+91): a 10-digit number starting 6–9 is an Indian mobile.
- Valid E.164: a + followed by 12 digits, nothing else.
Market brief
London and India, since the trade deal
What has changed on the route between an Indian supplier and a London buyer, from the UK government's own trade pages.
- 01
The UK and India signed their trade deal on 24 July 2025, after negotiations launched on 13 January 2022, and it entered into force on 15 July 2026.[1]
- 02
The Department for Business and Trade expects it to increase bilateral trade by £25.5 billion a year in the long run, and UK GDP by £4.8 billion.[2]
- 03
India's tariffs on whisky and gin halve from 150% to 75%, falling to 40% by year ten, and automotive tariffs go from over 100% to 10% under a quota.[2]
- 04
On the import side, the government says UK shoppers could see cheaper clothes, footwear and food products.[2]
- 05
Ofcom recommends 020 7946 0000 to 0999 and 07700 900000 to 900999 for drama and says they will not be allocated to providers in the foreseeable future, which is why this page uses them.[3]

What an Indian team uses to write to London
The parts of InfiQ that matter once the customers are in the UK capital.
- Template manager and library
Draft order, dispatch and appointment templates in en_GB and track each one through Meta's approval before your first London send.
- Consent records and opt-out enforcement
UK marketing turns on PECR consent as well as Meta's opt-in, so each London contact's opt-in source and time is kept, and STOP blocks later sends.
- Shared team inbox
London replies land through the Indian afternoon and evening; roles and transfers let whoever is on shift pick them up in order.
- Integrations over the API
A Shopify or WooCommerce store selling to London connects through the API and webhooks today; native one-click connectors are still in development.
