BT and Sky are the UK's two largest broadband providers — and they are locked in a constant battle for customers. But which one actually delivers faster speeds in practice? Here's what real speed test data from UK users shows.
The speeds below come from real user speed tests submitted on this site. Want to add yours? Run a test now — your result is anonymously included in our provider comparisons.
Quick Verdict
- Raw speed: Very similar on equivalent plans. Full fibre plans from both reach 900+ Mbps peaks.
- Consistency: BT Edge (full fibre) tends to deliver more consistent speeds at peak times in our data.
- Ping: Both are competitive. Full fibre plans from either sit at 5–15ms typically.
- Price: Sky is often cheaper on entry-level plans; BT offers better bundled TV/mobile deals.
- Best for most people: Sky for value — BT if you want a one-provider bundle (broadband + TV + SIM).

Ping & Latency Compared
For gaming, video calls, and real-time applications, ping matters as much as raw speed. Both BT and Sky deliver competitive latency on their full fibre products:
- BT Full Fibre: Typically 8–15ms ping on our test data. Consistent even at peak times.
- Sky Ultrafast+: Similar range, 10–18ms typical. Sky Q router placement affects this significantly.
- BT FTTC (older copper plans): 20–35ms typical. Fine for most uses, noticeable for competitive gaming.
- Sky FTTC: Very similar to BT FTTC. Latency is determined more by the Openreach line than the ISP at this tier.
Key insight: BT and Sky both use the Openreach network for FTTC connections. The physical line quality is identical — the difference is only in their core network routing and congestion management.
Packages & Pricing (2026)
Broadband pricing changes frequently — both BT and Sky run regular promotions. These are representative figures as of early 2026:
| Plan Type | BT | Sky |
|---|---|---|
| Entry fibre (~36 Mbps) | ~£28/mo | ~£25/mo |
| Superfast (~67 Mbps) | ~£34/mo | ~£32/mo |
| Full fibre 150 Mbps | ~£40/mo | ~£38/mo |
| Full fibre 500 Mbps | ~£50/mo | ~£48/mo |
| Gigabit (900+ Mbps) | ~£60/mo | ~£55/mo |
Sky is typically marginally cheaper at each tier, but BT regularly offers significant discounts for bundling TV and SIM contracts. Always check both providers' current offers before committing.
Full Fibre (FTTP) Availability
Both BT and Sky primarily use the Openreach full fibre network for FTTP. This means availability is identical between the two — if BT can offer you full fibre, so can Sky. Coverage had reached approximately 60% of UK premises by early 2026, with the government's Project Gigabit scheme accelerating rollout in harder-to-reach areas.
Check your address on the Openreach checker or contact either provider directly. If full fibre isn't yet available, both offer FTTC as a stopgap — speeds up to 80 Mbps in most cases.
Customer Service & Reliability
Ofcom's annual complaints data consistently shows both BT and Sky above the industry average for customer satisfaction, though neither is complaint-free. Key differences:
- BT: 24/7 phone support included. EE (BT's mobile arm) integration is improving. Premium support tiers available.
- Sky: Strong app-based support and proactive network monitoring. Sky Q hub app makes router management straightforward.
- Faults: Both use Openreach engineers for line faults. Response times are broadly similar — 3-5 working days for a non-urgent fault.
Who Should Choose BT vs Sky?
Choose BT if you...
- ✓ Want a single provider for broadband, TV, and SIM
- ✓ Value 24/7 phone customer support
- ✓ Are an EE mobile customer (discounts available)
- ✓ Want BT Sport included in your package
Choose Sky if you...
- ✓ Prioritise value at equivalent speeds
- ✓ Already have Sky TV or want Sky Sports/Cinema
- ✓ Prefer app-based account management
- ✓ Want a cleaner, more modern router design
For most people without strong brand loyalty, the decision comes down to whether you need TV bundled in and which provider has a better promotional price at the time of signing. Use our live ISP speed profiles to see current real-world speed data from UK testers on each network.
FAQ
Is BT broadband faster than Sky?
On equivalent plans, speeds are very similar because both use the same Openreach network infrastructure. The difference is marginal and often within the margin of testing variability. Full fibre plans from both deliver 900+ Mbps peak download on gigabit packages.
Can I switch from BT to Sky without losing my number?
Yes — your landline number is portable in the UK. Sky handles the transfer process when you sign up; you don't need to contact BT directly. The switch typically completes within 10–14 working days.
Which is cheaper — BT or Sky?
Sky tends to be marginally cheaper on standalone broadband at equivalent speed tiers. However, BT regularly runs promotions that close this gap, especially for customers bundling TV and mobile. Always compare live prices directly — deals change monthly.
Do BT and Sky both offer full fibre?
Yes — both offer FTTP (full fibre to the premises) where it's available. Availability is determined by the Openreach network, which both providers use, so if one can offer it at your address the other almost certainly can too. Check availability at your specific address before choosing a plan.
