Hi James and
I would have thought that it would be the necessity for planning permission rather than building regulations that would prevent you from having a satellite dish. Satellite dishes don't necessarily have to be fitted to the exterior of the house and can be fitted to a garden wall or pole in the garden which may remove the need for planning permission. I would check with your local council planning department for alternatives that you could use that are ok with them. Have a look at
http://europa.eu.int/comm/internal_m...antenna_en.pdf and remind the planning office about this directive.
There are less obstrusive satellite dishes than the standard sky supplied dish and even a satellite aerial. Have a google for these, one site being
