Starlink and satellite broadband in the UK: is it right for you?

If your address can’t get a decent fixed line and mobile coverage is patchy, satellite is the option that works almost anywhere with a view of the sky. Modern low-Earth-orbit (LEO) services — Starlink being the big one in the UK — have made satellite genuinely usable for everyday internet. Here’s what to expect, and when something else is the better buy.

Why modern satellite is different

Older satellite broadband used satellites in geostationary orbit, about 36,000 km up. Every request travelled there and back, so latency (the round-trip delay) was often over 600 ms — video calls lagged and online gaming was effectively out.

Low-Earth-orbit constellations sit a few hundred kilometres up instead. The result is latency of a few tens of milliseconds — in the same league as many fixed lines. That’s the single biggest change: satellite is no longer just “web pages and email”.

Not sure what latency means for you? See what is a good ping? and test your current line with the ping & latency checker.

Realistic performance

Real-world UK Starlink speeds commonly land in the tens to low hundreds of Mbps down, with much lower uploads, and they vary by area, time of day and plan — satellite capacity is shared, so busy cells slow down. Starlink shows a service estimate for your specific address when you check availability; treat that, not headline numbers, as your guide.

For context on what those speeds cover in practice, see what speed do I need?.

What you need to run it

1. A clear view of the sky. Trees, chimneys and valleys cause drop-outs — the dish needs an unobstructed cone of view. Starlink’s app can check obstructions from your garden or roof.
2. Somewhere to mount the dish — ground pole, wall or roof. Renters and flat-dwellers: agree it with the landlord first.
3. Power and a router — the kit includes one; you can add your own mesh if the property is large (see the extender vs mesh chooser).
4. Budget for hardware plus a monthly subscription. Prices and plan names change — check the current figures on Starlink’s UK site rather than third-party summaries.

When satellite is the right call — and when it isn’t

Your situation	Better fit
No usable fixed line, weak mobile signal	Satellite — it’s built for exactly this
No fixed line, but solid 4G/5G outdoors	4G/5G home broadband — usually cheaper; check with our 4G/5G checker
Decent full fibre available	Full fibre — cheaper, faster uploads, lower latency
Mobile home, boat or touring	Satellite’s portable tiers work, but weigh cost against a data SIM — see rural, renter & caravan internet
You need a fallback for outages, not a main line	A cheaper 4G/5G backup usually wins — see the backup internet planner

Before you commit

• Check the address-specific estimate on Starlink’s site, not averages.
• Compare against 4G/5G at your address — if a mast serves you well, fixed wireless is usually the cheaper monthly bill.
• Plan the mounting spot with the obstruction checker before paying for hardware.
• Think about uploads and video calls — uploads are the weak side of satellite; if you livestream or send big files daily, a fibre line (where available) is worth more.
