I also think that Mrs  somewhat underestimated the formal hours required, I have noted from the er, the B M A documents setting out the charges to be expected to be levied by agencies in relation to nurses that extra hours will be charged per hour and I can foresee that if an agency contracts to provide ten hours  formal care that er, it might be that with a number of carers they would find themselves very, very frequently putting in for extra hours of care.
