amanda - is your place directly through the landlord or through an agent??? from experience sometimes the agents don't pass things on, if they do they often don't followup to get responses?? the other thing is if you notify them of the pavers and they do nothing their public liability insurance company will want to know if anything does happen - let alone any negligence in not getting them repaired that will be their direct responsibility (Rory might know more about the negligence aspect) - I'd be raising the paving one in writing if it is getting to the dangerous stage.
