Coverage analysis — WD3
No network wins Watford on coverage. All four are within 1 point of each other in Ofcom's measurements, across 63 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 Watford as a whole.
Ranked by Ofcom's overall score: EE 100, O2 100, Vodafone 100, Three 99. The spread between best and worst is 1 point, 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 WD3?
EE's 5G rollout in Watford is among the strongest nationally, covering 100% of premises in the WD3 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 WD3 is O2 at 100/100 (100% 5G / 100% 4G). It is a close contest — both operators deliver strong coverage in WD3, and your choice may come down to tariff, handset preference, or existing contract.
Choosing a network in Chorleywood
Every network reaches Chorleywood, Sarratt, Chenies and Batchworth to the same standard in Ofcom's data (within 1 point), 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.
