UK broadband comparison Starlink, fibre or 5G?
If you can get full fibre, start there. If you cannot, try the mobile networks at home. Starlink becomes a much stronger choice when both let you down and you have somewhere with a clear view of the sky.
What the prices and speeds look like
These are advertised UK examples checked on 25 September 2026. BT and Three represent fibre and mobile alternatives, not the whole market. Every provider still needs to check your address.
Scroll across the table to see speeds and terms.
A speed cap, an advertised fibre speed and a measured mobile average are different things. None tells you exactly what your home will get. Three’s average applies to at least half its 5G broadband customers in 5G coverage areas at peak times. Starlink speeds vary with congestion and the dish’s sky view.
Price and plan sources: Starlink, BT and Three. These are the offers displayed when checked, including scheduled price changes. Other packages and address-specific offers may differ.
Look beyond the download number
For video calls, a connection that keeps dropping is frustrating even when a speed test looks good. Check upload speed, latency and short outages as well as download speed. Our calls and gaming guide explains what each affects.
For price, include the bill after any introductory period, announced increases and equipment you actually need. A £40 Starlink plan with the eligible referral credit costs £440 for the first 12 months of service at an unchanged monthly rate. The dish offer, delivery, mounting and electricity sit on top of that.
If you rely on a home phone, alarm or telecare device, settle how it will work before replacing the line. A new internet connection alone does not transfer those services.
Start with Ofcom’s broadband and mobile checker, then confirm the result with providers. For Starlink, use the app to check the intended dish position as well as checking the address.
