Depending on your location in the village the internet speed you receive varies considerably. Having moved to the village from West Bagborough in the Quantocks I am aware that there are schemes to deliver Internet into Exmoor other than via the traditional phone line.
More details are on the Connecting Devon and Somerset website at this page where you can enter your postcode and find out what options there are for you. You can also begin an enquiry via the Airband website who are the suppliers of the alternative service, in the diagram above.
I’m not clear on who pays for what, there was originally a voucher scheme to fund installation of some of this equipment that has been discontinued.
I tried our own postcode on the Airband site, and it indicated that their service is available to us in the lower village. You’ll have to check your own postcode to find out the options and pricing for your home or business.
