How NetScan works

Your postcode

We send your postcode to Ofcom's Mobile Coverage API, which reports each network's signal at the addresses in that postcode.

Ofcom's measurements

For each network: the share of those addresses with enhanced (5G-grade) outdoor signal, good outdoor 4G, and good indoor signal. No reading for your postcode? We show Ofcom's district or area figures and say so.

One score per network

35% 5G-grade + 50% 4G + 15% indoor. When all four are within a few points, we say no network wins rather than crown one.

Phones and plans

Links to phones sold by the strongest network, on its own site. No prices here: networks change them, so we send you to the live page.

FAQ

How does NetScan UK determine the best mobile network for my postcode?

NetScan UK asks Ofcom's Mobile Coverage API about the addresses in your postcode and scores each network: 35% enhanced (5G-grade) outdoor signal, 50% good outdoor 4G, 15% good indoor signal. If Ofcom has no reading for the postcode, you see Ofcom's figures for the district or area, labelled as such.

Does NetScan show phone prices?

No. Networks change phone prices often, so NetScan links each phone to its page on the network's own site, where the price is current.

Is NetScan UK free to use?

Yes, and there is no sign-up. The site uses Google Analytics to count visits, and the postcode you enter is sent to our server to look up Ofcom's data.

Why do I see different rankings for nearby postcodes?

Because Ofcom measures real addresses, and signal genuinely differs from one postcode to the next. Each result shows how many addresses Ofcom sampled.
