ive checked pretty much everything i can.
its at the garage on thursday i just wanted to have a idea for cost etc.
cheers anyway mate
Sorry I cant be more help, you need to establish what the drain is on the battery first to know where to start looking, the only way to do that, is measure it.
I don't want to talk down your Garage, but most don't like to get involved in electrical problems, as someone on here (who shall remain nameless) said, its a black art to most mechanics.
Try taking it into somewhere like Lucas Services, or a good auto-electrician.
They have a better understanding and the test equipment to do it quickly. Could work out cheaper in the long run, and you will get a proper answer rather than a stab in the dark one.
FWIW
