How to Stay in London for Free (or Very Cheap)

True "free" stays are rare, but these strategies minimize costs:

1. Couchsurfing: Stay with verified hosts via the Couchsurfing platform.
2. Hostels: Dorm beds from £20–£40/night; some offer work-exchange.
3. House Sitting: Free accommodation in exchange for pet/home care (TrustedHousesitters, etc.).
4. Camping: Designated sites (e.g., Lee Valley, Crystal Palace) in warmer months.
5. Volunteer for Accommodation: Organizations like Workaway, WWOOF, HelpX offer room/board for ~20–25 hrs/week work.
6. University Halls (Summer): Vacant student rooms rented cheaply (June–Sept).
7. Workaway / Worldpackers: Cultural exchange for lodging.
8. Home Swaps: Swap your home with a Londoner (HomeExchange, Love Home Swap).
9. Friends / Network: Reach out to contacts.
10. Church / Community Hospitality: Some churches offer temporary stays for travelers.

Plan ahead, verify hosts, and read reviews.
