Free pizza, cups of tea and spare phone chargers were offered up by local residents in Parsons Green following the explosion on the Tube.
West Londoners fastened signs to their front doors telling anyone affected to come if they need anything from a beverage to a toilet break.
At the fringes of the police cordon, Teo Citino, the owner of nearby restaurant Il Pagliaccio, piled a fold-out table with free pizza for the emergency services.
One of the reasons I'm here is that my wife and daughter could have been on that train, I live next to the station.
Other residents from near the site of the attack approached members of the press and offered them access to phone chargers and a place to sit down inside.
Hammersmith and Fulham Council was also on hand, opening a local community centre as a rest place for those whose homes were within the police cordon.
A Chelsea and Fulham Dentist, a five-minute walk away from the Tube station, also offered people a place to shelter.
Dentist Dahlia Sunba, who co-owns the practice with her husband, said: "I could see people wandering around aimlessly.
"We can see helicopters overhead. It's a little bit unnerving and people look slightly distressed.
"We have tea and coffee and biscuits. We're more than happy to give them a cup of tea or coffee.
"There's lots of plug sockets if they need to charge their phone or make a call."
