Spending on fire safety works is expected to reach £661m, according to data compiled by Tussell, a data provider on UK public procurement.
Some 221 tenders have been published, up 56% on the previous year.
Work will include servicing sprinkler systems and fitting and upgrading fire alarms.
The top 10 tenders alone could be worth as much as £593m, issued by bodies including Re:Allies, Northern Housing Consortium and Fusion 21.
There was a 39% increase in fire safety tenders from housing associations while local councils published twice as many as the prior year.
Gus Tugendhat, founder of Tussell, said: “The data shows a surge in tenders for fire safety work in the year since the Grenfell Tower tragedy.
“It is heartening to see that Grenfell has prompted long-overdue investment in fire safety across the wider public sector — particularly in local government.”
