Hi @Helmside31 should be very good for it, I get great results with only a 30 Mbps service. Needless to say there are many variables and if your cottage has metre thick granite walls and despite contracting for fibre 65 the speeds could be significantly lower.
What guaranteed speeds are you being offered?
