Coverage analysis — KW9
No network wins Kirkwall on coverage. All four score identically in Ofcom's measurements, across 57 addresses sampled in 6 postcodes. On a difference that small, EE, O2, Three and Vodafone will all work here — so choose on price, contract length and roaming, not on a coverage map. Coverage only becomes the deciding factor once you leave built-up areas, and it still varies street by street indoors: check your own postcode below to see the measurement for your address rather than for Kirkwall as a whole.
Ranked by Ofcom's overall score: EE 100, O2 100, Three 100, Vodafone 100. The spread between best and worst is 0 points, which is inside the margin where a coverage figure stops being a useful tiebreak. Ofcom's data describes outdoor signal across sampled addresses; it cannot tell you how any of them behave inside your own building.
Why EE for KW9?
EE's 5G rollout in Kirkwall is among the strongest nationally, covering 100% of premises in the KW9 district. For anyone streaming video, gaming on mobile, or relying on a mobile hotspot at home, this level of 5G penetration makes a real difference to day-to-day speed.
The runner-up in KW9 is O2 at 100/100 (100% 5G / 100% 4G). It is a close contest — both operators deliver strong coverage in KW9, and your choice may come down to tariff, handset preference, or existing contract.
Choosing a network in Edderton
Every network reaches Edderton and East Sutherland to the same standard in Ofcom's data, so coverage cannot pick one for you here — price and contract length can. Compare what each is charging, then check the exact street you live on before you commit, because indoor signal still varies where the area figures match.
