Yes, you can park your car at London Heathrow (LHR) for a week in 2026, but the cost and convenience vary by the type of service you choose. The most economical option is Long Stay Parking, which involves parking in a peripheral lot and taking a free 10–15 minute shuttle to your terminal; a week here typically costs between £100 and £160 if pre-booked. For more convenience, Business Parking offers shorter shuttle times, while Meet & Greet allows you to drop your car at the terminal with a valet. The most expensive option is the Short Stay Car Park, located directly adjacent to the terminals; while intended for pick-ups, you can stay for a week, but "drive-up" rates in 2026 can exceed £700 for seven days (£98 per day). To get the best rate in 2026, you should book your space at least 30 days in advance via the official Heathrow website; "on-the-day" prices are significantly higher and spaces are not guaranteed, especially during peak holiday periods when lots frequently reach 100% capacity.
