So here is an email I got from Bristol Groundschool:

Thank you for your e-mail and interest in Bristol Groundschool. Please visit
our web-site for full details on how to convert your current licence and the
requirements. www.bristol.gs I believe you will need to sit and pass all 14
exams at ATPL level but do not have to complete an approved course of
training as you hold a foreign ATPL already.

You may only be required to pass the Air Law & Human Performance exams for
UK registered Aircraft.
This can be confirmed by visiting our web-site under requirements. Any
further licence queries should be e-mailed to Flight Crew Licensing
[email protected] at the UK CAA.

The course can be bought in 2 modules, Module 1 = £1,300 plus shipping,
Module 2 when you're ready = £800 plus shipping. If you require an approved
course up must attend the 2 x 2 week brush-up course's held here at Bristol.
These are included in the £2,100 and our CBT CD rom.

Or you can just buy the DVD which covers all 14 of the subjects for £490, or
if you just want the manuals these can be purchased for £950 plus shipping
if outside the UK.

We do not offer any flight training, you may wish to contact Bristol Flying
Centre www.b-f-c.co.uk for details on these requirements or any of the CAA
approved providers.

If we can be of any further assistance please do not hesitate to be intouch.

With kind regards,

Anouska

Since I hold a ATP license already it looks like it makes it a little easier. The biggest problem is the 2 x 2 week class sessions because I have to work while I am doing this course, plus finding lodging must be expensive in England. Also, does anyone know what aircraft are approved for the 15 hour flight requirement? I am hoping that I can do this in GA airplane to keep the cost at minimum. I assume the flight training can be done at any JAA approved flight school. What is the cheapest place (country) to get this done?

I am sorry for all the questions, but I am just trying to do this the right way and before I spend the money I want to make sure that the investment is done the right way. Thanks for all the help and input so far.
