City Hall has partnered with major businesses to form the charity which will make grants to businesses which suffered robbery and fire damage during the unrest.
Shell’s donation takes the amount pledged to over £4 million, including £500,000 provided by the Greater London Authority for assisting businesses within the capital.
Mayor Johnson said the money “will go a very long way in helping businesses to get back on their feet.”
Shell UK Chairman Graham van’t Hoff said the firm was “glad to be supporting the High Street Fund.
“We look forward to watching the small businesses and communities most affected by the riots recover quickly as a result of this great initiative.”
The company joins Barclays, BP, Capita, Deloitte, Lloyds Banking Group, RBS and Santander in backing the initiative.
The Fund’s Chairman, Sir William Castell said: “Shell have dug deep to support hard-pressed small companies and we are so grateful for their support. Claims from the fund are now coming in and with Shell’s generosity we’ll be able to help many more local businesses.”
On Friday the BBC reported that just 20 businesses had applied for assistance and of these, only two had so far received support.
