depends on the equipment fit they go for, i would imagine for the London fire brigade they don't need to worry too much about power supplies so may not need such a powerful generator etc. same for communications fit etc. the London WIFI/4/5g  networks are a lot more reliable than say parts of wales or Northumberland so needing portable masts etc shouldn't be a problem.
