To answer Liam's point, we need to distinguish between NWP models that run on a handful of supercomputers around the world, usually developed by the largest national met agencies, and other types of model which are more commonplace which we do have, such as road forecasting energy balance models. It is up private sector forecasting companies to develop a business case for the purchase and use of global model data. There's nothing new about this - us and others have been doing this for decades. We could hardly compete otherwise now could we? I hope this clarifies.
