Here's the reply I got from the UK MET office! :) Hope it helps.
You may find our free datapoint service to be suitable to your needs: http://www.metoffice.gov.uk/datapoint
DataPoint is a way of accessing freely available Met Office data feeds in a format that is suitable for application developers. It is aimed at professionals, the scientific community and student or amateur developers, in fact anyone looking to re-use Met Office data within their own innovative applications.
Access to data includes:
forecast and observation map layers such as radar and cloud cover for the UK;
forecast and observed site specific data such as temperature, wind speed and direction; and,
regularly updated text forecasts for mountain weather, national parks and UK regions.
We have quite a lot of online support available for datapoint on the links below, which may provide you with some guidance if required.
Furthermore detailed user documentation and guides can be found here: http://www.metoffice.gov.uk/datapoint/support/documentation
We also have a small but dedicated datapoint community forum which may be able to provide you with more immediate real-time support from fellow members:
Finally if after reviewing the above links you still require support or desire a more custom/commercial feed then please provide a little more information about your requirements, which data you wish to use and how you wish to use it and we will be in a better position to assist with your enquiry.
