Loss adjusters from GAB Robins, Cunningham Lindsey and Watermans are surveying the extent of damage caused by the detonation of a terrorist car bomb in Ealing in the early hours of Friday morning.
Shops and commercial premises around the blast site in Ealing Broadway, west London suffered blast damage and seven people were injured by flying glass.
A spokeswoman for GAB Robins said it was dealing with a number of claims from the attack.
Police say the bomb was twice the size of the device that exploded outside the BBC's White City headquarters in March.
