The last time you went to a house party that didn’t run out of drinks, Smartie Artie was serving orange squash in paper cups.

These days to keep the drinks flowing you’ll need the help of The Lock In — a delivery service providing alcohol (wine, spirits, beer and liqueurs) between the hours of 6 p.m. and 6 a.m. every night.

Ask nicely and they’ll also bring you other late-night/early-morning necessities like cigarettes, water, loo roll, snacks or a newspaper. Delivery takes up to 30 minutes in and around Central London, including Hammersmith, Holborn, Camberwell and Waterloo.

There might not be jelly or going home presents at this party.

But we promise there’ll be lots of people acting like children and just as much mess.

The Lock In (020 7350 2424 or latelondon.co.uk).
