Unfortunately for those of you contemplating making your services unavailable for EU customers outside of the UK, you fall fowl of the EU anti-discrimination laws, due to us having open trade borders. This might not ever catch up with you, but it is a risk nonetheless. I am waiting for full clarity from HMRC, but there do seem to be suggestions that you can register for MOSS and pay VAT on your non-UK sales, but it doesn’t have to impact your UK sales. If so, that would help a lot. http://www.taxamo.com are hosting a webinar with HMRC tomorrow (Tues), so hopefully they will give some clarity on this then.
