There are currently three 24 hour off licences in the London Borough of Greenwich:
Asda, Bugsby's Way, Charlton, SE7 7ST - 020 8858 3313
Kash For Wines, 829 Woolwich Road, Charlton, SE7 8LJ - 020 8316 5367
BP Connect Petrol Station (Crown Woods Service Station - Eltham South), 21 Crown Woods Way, SE9 2NL - 020 8859 2481 (Not currently serving alcohol at night)
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).
