There are currently three 24 hour off licences in the London Borough of Havering:
Tesco Extra Gallows Corner, Bryant Avenue, Romford, Essex, RM3 0LL - 01708 799400
Tesco Extra Romford, 300 Hornchurch Road, Hornchurch, Romford, RM11 1PY - 01708 797500 (Not currently open 24 hours)
Asda, The Mall Shopping Centre (Liberty 2), Mercury Gardens, Romford, Essex, RM1 3EE - 01708 388700 (Not currently open 24 hours)
Please Note: Just because a shop is listed as having a 24 hour alcohol licence doesn't necessarily mean that the shop is open 24 hours a day, 7 days a week. It's also worth noting that large 24 hour supermarkets (Asda, Sainsbury's and Tesco) are not open all night on Saturday, Sunday and bank holidays (due to Sunday trading laws in England and Wales).
