For the first time I am in the position to have a mains plug available all winter.How do I setup an automatic charging system to my two batteries (ie Starter & leisure)plus I would like to install two small thermostatic tube heaters.

You will need a two output multi-stage battery charger, ideally from a reputable source. One output would be connected to one battery bank allowing one charge to charge both banks. However as the engine battery is usually fully charged by the engine using a charge on it may be overkill. If it ever did get discharged a simple jump lead between both banks' positives would charge it. For maximum safety and to comply with bets practise you will also need an RCD, mains consumer unit, an isolation transformer or As you have not mentioned these items I think you would be well advised to employ a marine electrician who understands mains on boats to install the system - remember mains can kill if you get it wrong.
