BT Full Fibre 150 gives you a true fibre-to-the-premises connection offering average download speeds of 150 Mbps and upload speeds of 30 Mbps . According to BT, it’s suited to homes with 5–8 connected devices, supporting activities such as streaming, downloading, remote working, social media, and general browsing.
In addition to the ultrafast speeds, the package includes a Smart Hub 2 router. You can also add BT’s Halo / hybrid features and these offer extra reliability (i.e. a mobile backup connection via EE) and more robust Wi-Fi covering your home.
BT also backs this with a “Stay Fast Guarantee” (i.e. they promise a minimum speed threshold, and offer remedies if your speed falls persistently short).

This package is ideal if you or your household:
- Have multiple users streaming (e.g. Netflix, Disney+, Apple TV) at once, perhaps in different rooms.
- Work from home and need reliable video calls, cloud uploads, or file transfers.
- Download large files, game online, or host online meetings.
- Choose your broadband without jumping to the most expensive options.
If instead you only browse, check email, or stream in one room, a lower tier might suffice. If your household is very heavy (many simultaneous 4K streams, large uploads) then stepping up to a faster package will be a better choice.
Pros
- You get a fast, modern full fibre connection (150 Mbps down / 30 Mbps up)
- No upfront cost to install or set up.
- The price is competitively low initially compared to some other providers’ full fibre offers.
- Minimum guaranteed speed of 100Mbps. The “Stay Fast Guarantee” offers protection: if your speeds consistently drop below this threshold, BT may fix the issue or allow you to leave early.
- You can (in many cases) add BT Halo or hybrid backup options, giving better and faster connectivity.
Cons
- The price hikes built into the deal (in 2026 and 2027) mean your bill will not remain constant.
- Upload speed is asymmetric and somewhat lower than what you might get from fully symmetrical providers (i.e. some full fibre rivals).
- The Smart Hub 2 router does not support Wi-Fi 6 (which newer routers from rivals might).
- Some add-ons (mesh Wi-Fi, backup mobile connectivity) come at additional cost.
Is BT Full Fibre 150 Any Good?
From the user and industry reports, BT Full Fibre 150 generally delivers reliable performance. Reviewers observe that BT’s full fibre service typically outperforms part-fibre (hybrid) plans, with lower latency and fewer issues related to copper degradation.
BT’s “Stay Fast Guarantee” gives added peace of mind: for Full Fibre 150, they guarantee a minimum speed (typically around 100 Mbps). If your speeds fall below that consistently, they are obliged to try fixes, and you may be able to exit without penalties.
In surveys and independent reviews, BT’s overall broadband rating is solid (often 4 out of 5) for speed, reliability, and customer satisfaction.
However, BT is seldom the cheapest among providers offering similar fibre speeds — competitors may undercut on price or offer symmetrical upload speeds.
When compared with other providers (e.g. Sky, Virgin, alternative network providers), BT tends to compete more on reliability, brand trust, and extras rather than raw price advantage.
The fact that BT can add hybrid backup (via Halo) is a differentiator in terms of resilience.
One caveat: because BT builds (or leases) the fibre infrastructure via Openreach, in very tight geographic or rural areas the full fibre rollout may not yet have reached you, or performance may depend on distance and local quality.
Alternatives Worth Considering
- BT’s faster tiers (e.g. Full Fibre 300, 500, 900) — these plans come with faster downloads, and better upload speeds.
- Other full fibre providers or alternative network providers (e.g. CityFibre, Hyperoptic, Virgin, etc.) — some of them offer symmetrical upload/download speeds or lower long-term cost.
- Hybrid or backup broadband packages (if you don’t need full fibre but want fallback connectivity) — these may cost less but with more variable performance.
- Lower-tier fibre plans (for lighter users) — if your usage is modest, a cheaper plan might suffice without the overhead.
When comparing, check not only monthly price but also how often price rises occur, what extras (mesh Wi-Fi, customer support, backup) are included, and whether you get a guaranteed minimum speed or compensation when performance drops.
Our Verdict
BT Full Fibre 150 is a competitive mid-tier full fibre broadband package offering excellent value for households that need more than entry-level speed but don’t require ultra-fast gigabit service.
The no-upfront cost, inclusion of a reliable router, and the Stay Fast Guarantee make it particularly appealing. The built-in price increases must be accepted, but these are disclosed up front.
Provided your address is eligible for full fibre, and you want a balance of speed, reliability, and manageable cost, this is a good choice.
If your household is extremely demanding or uploads heavily, you may want to explore the faster options or providers offering symmetrical speeds.

FAQ — BT Full Fibre 150
Q: How do the price rises work?
A: You pay £27.99/month at first, but as per BT’s terms the price increases to £31.99 from 31 March 2026, and then to £35.99 from 31 March 2027. These are built into the contract.
Q: What is the upload speed?
A: Up to 30 Mbps (this is typical but can vary depending on your local line and network conditions).
Q: Will I get the full 150 Mbps all the time?
A: Not always. Actual speeds can vary due to network congestion, local line quality, your in-home Wi-Fi setup, distance, etc. That said, because it’s full fibre (no copper), the variation is less than in older fibre/copper mixes.
Q: What is the Stay Fast Guarantee?
A: BT sets a minimum performance threshold (for Full Fibre 150, generally around 100 Mbps download). If your connection persistently falls below that threshold after BT has had the opportunity to fix issues, you can receive compensation or leave the contract penalty-free.
Q: What happens at the end of the 24-month contract?
A: You will likely revert to a “standard” renew rate unless you switch or renegotiate. You may also face further price changes beyond the 24-month period.
Q: Do I need to pay for installation?
A: No, in this deal the upfront cost is £0 (i.e. no installation or setup charge).
Q: Can I add resilience in case the line fails?
A: Yes, via BT Halo or Hybrid Connect in many areas. If your fibre link drops, your connection can automatically switch to EE’s mobile network as a backup.
Q: What router is provided?
A: The Smart Hub 2 is standard with BT full fibre packages.
Q: If I move home during the contract, can I take this plan with me?
A: Possibly — as long as the new address is eligible for BT full fibre. If not available there, you may need to switch to another plan or provider.
