Westfield London has enraged retailers by pushing up its service charges just days after the centre opened for business.
According to a report in The Financial Times, Sir Philip Green's Arcadia Group and New Look are among the retailers gearing up to fight against the proposed 75% increase in the charge which covers costs from marketing to cleaning at the centre.
Retailers said that they were given a guideline for the annual cost of about £8 per sq ft, but now are being asked to pay almost £14 per sq ft.
According to the newspaper, not all stores have received notification of the change to the charge.
The higher than expected charge could push up costs for some retailers at the centre by more than £500,000 a year.
Westfield declined to comment on the specifics but said that the charge reflected the centre's "premium offer and service levels."
