A few people have now told OP that as an adjoining owner they have the same legal rights with or without the Party Wall Act however they left out one important detail.
If the OP can get the work included in a Party Wall Award it should not cost them a penny as the person undertaking the work, quite rightly, should pay for the surveyor. If they choose not to pursue the neighbour to instigate the Party Wall Act and say the neighbour punches the steel beams right through the party wall into the OP's loft (yes we have had posts on here where that has happened) then it is up to the OP to pay for their own legal representation and probably court costs etc. with no guarantee they will be reimbursed.
As an adjoining owner its a no brainer really, if the neighbour wont do the job properly then approach a party wall surveyor yourself. A well worded letter to the neighbour from the surveyor pointing out the folly of continuing the work without a party wall award and the huge costs if they try to proceed and the likely serving of an injunction usually does the trick.
