BT Broadband Review

BT's current Full Fibre range runs from Full Fibre 150 at £23.99 a month, through Full Fibre 300 at £25.99 and Full Fibre 500 at £27.99, up to Full Fibre 900 at £31.99. A part-fibre Fibre 2 package, averaging 67 Mbps, is also available at £24.99 for addresses full fibre has not yet reached. Every package carries a £30 upfront setup fee.

BT offsets that setup fee with a reward card, ranging from around £80 on the entry tiers up to £140 on Full Fibre 900. This only works out in the customer's favour if the card is actually claimed and used; treat the setup fee as a real £30 cost at the point of paying, not a number cancelled out automatically by a reward that requires separate action to redeem.

Every package is sold on a 24-month contract, with no shorter or rolling option currently published. A £4 a month price rise applies every March, disclosed upfront on the price page rather than hidden in the terms, so the real two-year cost of any BT plan is higher than the first month's headline figure.

BT sells broadband over the Openreach network, the same underlying infrastructure used by most other national providers, including Sky, TalkTalk and Plusnet, as well as many smaller resellers. This means line quality and top available speed at a given address is largely the same regardless of which Openreach-based provider is chosen; the differences between them are price, contract terms, extras and support.

Full Fibre 900 is BT's flagship tier, backed by a Stay Fast Guarantee: if the actual delivered speed falls below a set minimum, BT states it will resolve the issue or pay out automatically, without the customer needing to raise a formal dispute first. This is a genuinely stronger consumer protection than a standard speed guarantee that requires an active complaint.

For most households, Full Fibre 150 or 300 comfortably covers streaming, browsing, working from home and several devices in use at once. Full Fibre 500 and 900 mainly benefit larger households running multiple demanding activities simultaneously, or anyone who specifically needs fast, consistent upload for cloud backups or video calls.

BT includes the Smart Hub 2 router on ultrafast full-fibre packages and with its Complete Wi-Fi service, and the original Smart Hub on other packages. Complete Wi-Fi is BT's paid mesh add-on for homes where a single router does not reach every room, and it carries its own money-back guarantee if signal issues are not resolved within a stated period after signing up.

The free BT Wi-Fi hotspot network, accessible to BT broadband customers at thousands of locations across the UK, is a genuine, if often overlooked, extra that some rivals do not offer at all, useful for anyone who travels regularly within the UK and wants to avoid using mobile data.

Anyone considering Complete Wi-Fi should first confirm there is a genuine coverage problem, rather than adding it automatically; a single Smart Hub 2 in a well-positioned spot covers most standard homes without an extra monthly charge.

Every current BT broadband package carries a flat £4 a month price rise each March, disclosed in pounds and pence rather than tied to inflation. This follows Ofcom's ban on inflation-linked, percentage-based price rise terms in all new contracts from 17 January 2025; BT, like most national providers, switched to a fixed cash figure as a direct result.

On a 24-month contract, that means the second year costs £48 more than the first at every tier, a real, disclosed figure that should be added to the headline monthly price when comparing BT against a provider with no scheduled rise, such as several of the full-fibre altnets covered elsewhere on this site.

This is not unique to BT; EE, Vodafone and Plusnet, all under the same corporate ownership structure or comparable market position, apply a similar flat rise. The genuine point of comparison is not whether a rise happens, but its size and whether a no-rise alternative is available at the same address.

Reviews consistently cite quick Full Fibre installation and professional Openreach engineers as a strength, consistent with BT's scale and its position as Openreach's parent-group-adjacent anchor customer.

Because BT runs on Openreach, most switches from another Openreach-based provider, Sky, TalkTalk, Plusnet and others, qualify for Ofcom's One Touch Switch process, a same-day handover with no need to contact the outgoing provider directly.

A switch from a provider on a separate network, such as Virgin Media's own cable infrastructure or a full-fibre altnet building its own fibre, will not use One Touch Switch, so keep the existing connection running until the new BT line is confirmed working.

BT has two separate, active Trustpilot pages, and they tell noticeably different stories. The bt.com page shows a rating around 4.0 out of 5 from more than 150,000 reviews; a second, older btbroadband.com page shows around 1.5 out of 5 from roughly 14,000 reviews. Both are genuine customer reviews; the difference comes from how each page is used, not from fabricated or removed reviews on either side.

BT actively promotes the bt.com page as its official feedback channel, including prompting customers after a positive interaction such as a successful installation or fault fix, which skews that page toward satisfied customers who were asked to leave a review. The older btbroadband.com page is less actively promoted and consequently attracts a higher proportion of customers who sought it out specifically to complain.

The practical takeaway is not to treat either number in isolation. Ofcom's own Q1 2026 complaints data is a more neutral cross-check: BT ranked third-worst for complaints, at 7 per 100,000 customers, an improvement from 8 the previous quarter, and below TalkTalk's 10 and Vodafone's 8, but still above the industry average of 6.

BT's real advantage is reach: at 98% of UK homes, it is available almost everywhere, which matters most for anyone who has already ruled out full-fibre altnets and cable due to lack of coverage. Its Stay Fast Guarantee and reward card system are genuine, not marketing-only, benefits if actually used.

It is not the cheapest option at any given speed, and its Ofcom complaints ranking, while improving, still sits above the industry average. The split Trustpilot picture is a fair reflection of a genuinely mixed but not uniformly bad service record, rather than a reason to dismiss BT outright.

Our take: BT suits a household that values broad availability and a well-known, established brand over the lowest possible price, and is prepared to actively claim the reward card and factor the scheduled March rise into the real two-year cost, rather than judging the deal on the first month's bill alone.
