Independent businesses are petitioning together to oppose the closure of a high street bank.
NatWest have confirmed that they intend to close the Harrow Weald branch, in High Road, in July, which would leave the area without a bank.
Traders have rallied together, calling on the national chain to reconsider.
Harrow Weald Dental Practice is one of the businesses that have started the petition.
Mita Patel, a receptionist at the clinic, said: “We feel quite strongly about this. The staff here and our patients do their banking there, and it is the only cash machine in the area.
“The only way to get cash would be to go into Harrow town if it goes. Many of our patients are signing the petition, so hopefully NatWest change their mind.”
The businesses have been supported by Labour's Harrow East parliamentary candidate Uma Kumaran.
She said: "Losing the last bank in Harrow Weald would be a real blow to our community and all the local businesses and residents who rely on it.
"NatWest call themselves the helpful bank but they're not listening to the traders in Harrow Weald who want the bank to stay. I'm writing to the chief executive urging him to rethink."
Concerns are now turning to what could replace the bank if it does decide to close.
Ms Kumaran added: "The last thing Harrow needs is more payday lenders or betting shops, but thanks to this Tory government's planning free-for-all, it has become harder for local councils to oppose them and protect our high street.
"I’ve spoken to local traders and residents alike, they’re all calling for the bank to stay and so am I.”
