I don't think making yourself the 'neigboour from hell' is your best chance of reaching an amicable agreement here. Most laws and bylaws allow noise after 7.30am and until 11 pm.
The thing is this would be a tort case. The English Legal system (civil) is very slow and by the time anything is done your neighbour will have probably have sold up and somebody else moved in - some tort cases have been known to take upto 3-4 years.
The best thing to do here, I suggest, would be to approach him again, tell him you are not happy with his nuisance at 6.30am (nuisance is a tort issue but that should be your last option really), if this doesn't work I would go to your solicitor and tell him/her. Solicitors can work on your behalf in an ADR system (Alternative Dispute Resolution). Your solicitor would write to him telling him firmly that you are not happy. The ADR would try to reach an agreement between you both, in a friendly 'Consilitation/mediation' type setting or am 'arbitration' setting - where the result is legally binding.
Im not a solicitor - this is just my advice as i have studied tort before.
Hope it all goes well for you.
