India is approximately 3.5 to 4.5 hours ahead of United Kingdom. Indian business hours (9:00 AM - 5:30 PM IST) overlap with British afternoon hours, making it convenient to contact the London embassy or Indian support lines during your workday.
Direct flights from London Heathrow to Delhi, Mumbai, and Chennai are frequent. British Airways, Air India, and Virgin Atlantic operate daily nonstop services averaging 8-9 hours.
Upon arrival in India, Britons should proceed to the e-Visa immigration counter (separate from regular visa lines) at the airport. Have your printed ETA, passport, and return ticket ready. Immigration processing typically takes 15-30 minutes. India uses the metric system, drives on the left side of the road, and the local currency is the Indian Rupee (INR).
