Pros and cons

Pros

  • Top download speed of 2,200 Mbps with uploads of 150 to 2,200 Mbps, so one line handles heavy streaming and heavy work.
  • A static IP is available, a detail most household broadband pages leave out.
  • A TP-Link / eero WiFi 6 router included is part of the package, taking a hardware purchase off the setup list.
  • Support runs on email, chat and phone, putting a phone line alongside live chat, email and a help centre.
  • Stated reach of 24,000,000 premises, wider than a single-town build.

Cons

  • The price is not fixed: price rises each April by GBP3, so the entry figure is not the figure a household keeps.
  • A £10 setup fee lands on the first bill on top of the monthly £27.50.
  • Every plan runs a 18-month contract, with no shorter term in the range.
  • It trades in GB alone, so a household outside that market cannot buy the service at all.

Who it suits

  • Households on a full-fibre line in GB that want top speeds of 2,200 Mbps without sourcing their own router.
  • Home servers, camera setups and remote workers who need a static IP, listed as available.
  • People who expect the bill to move, and would rather know the price rises each April by GBP3 rule up front than meet it later.

Who should look elsewhere

  • Households chasing the highest top speed, where Abissnet lists up to 10,000 Mbps.
  • Homes that want cable as well as fibre from one provider, since Astound runs cable and fttp while this brand runs fttp.
  • Anyone wanting a different connection type or a market outside GB, where EarthLink lists fttp, 5G and satellite.

Pricing

The entry point is £27.50 a month, and that figure belongs to the cheapest plan in the range rather than to the whole line. Two numbers decide the first bill: the monthly amount and a one-off £10 setup charge that has to be paid up front. Every tier above the entry plan costs more per month, so the headline number is a floor for the account, not a typical payment. Readers weighing tariffs should set the setup fee beside the monthly figure rather than reading the monthly figure on its own, since a low monthly price with an added setup charge can work out ahead of a slightly higher plan that costs nothing to start.

What it does well

Downloads reach 2,200 Mbps at the top of the range, with uploads running 150 to 2,200 Mbps, so a home can send as well as receive on the same line. A static IP is available, which is the feature that separates a connection like this from most household broadband and the one that matters for a home server, a camera feed or a fixed VPN endpoint. Stated reach covers 24,000,000 premises, though a footprint figure describes scale rather than certainty: what a given address can get depends on the line built to it, not on the top speed advertised here.

Where it sits among rivals

The comparison table gives a fair sense of scale. On max download speed the brand ranks 36 of 114 listed providers, on entry price 73 of 95, and on setup fee 61 of 86. The speed ranking is the stronger of the three, while entry price and setup fee both sit in the middle of their fields. Read together, these point to a provider recognised for headline speed rather than for the lowest monthly number, which is why the plan name and the setup fee should travel with any quoted price.

Who runs it

The service trades as The One Broadband and is provided by DSV Communications Limited, the entity named on the broadband pages and the name to deal with if a query needs to go to a company rather than a brand. Support runs on email, chat and phone, and a fault can be raised by whichever of those suits the situation. A phone line matters for outages, when a conversation tends to move faster than a ticket. Every route in that set is remote, so anyone who prefers a shop or a counter is outside what is on offer.

Frequently asked questions

What does The One Broadband cost to get started?+

The cheapest plan starts at £27.50 a month, and a £10 setup fee is payable on top when the service goes live. Plans carry names such as The Simple One, The Chosen One and The Everything One, and each step up the range costs more per month. Treat the entry figure as the floor for the account rather than an average of what households pay.

Does the monthly price rise after the first year?+

Yes. price rises each April by GBP3, so the amount a household signs up at is not the amount it keeps. Anyone budgeting over a long term should build the annual increase into the entry price of £27.50. It is a published rule rather than a discretionary change, which makes it easier to plan around than a provider that raises prices at will.

How fast is the connection, and what about uploads?+

Downloads reach 2,200 Mbps at the top of the range, and uploads run 150 to 2,200 Mbps, so the same line is used for sending and for receiving. That pairing suits households that work from home, run a home server or move large files in both directions. On speed alone this sits toward the upper end of the field.

Do I need to buy a router?+

A TP-Link / eero WiFi 6 router included comes as part of the package, so a hardware purchase is not part of setting the service up. The unit named covers the home network out of the box, which removes the main cost and setup task from a move. Anyone already running a mesh system can weigh whether to keep using that instead.

How long is the contract?+

Every published plan runs 18 months, with no shorter monthly term in the range at present. The term is the period over which the entry price of £27.50 and the £10 setup fee are locked, so anyone who may move during that window is better off planning for the whole of it rather than the first month.

Where is it available?+

The service runs in GB and its stated reach covers 24,000,000 premises. A footprint of that scale is spread widely rather than confined to a few towns, though the speed an address can get depends on which line reaches it. An address check is the practical way to confirm availability and the plans that can be ordered.

How do I get help if something goes wrong?+

Support runs on email, chat and phone, so a fault can be reported by phone, by live chat, by email or through the help centre. Having a phone line among those routes matters during an outage, when a conversation usually moves faster than a written ticket. All of the stated routes are remote, so a visit to a shop is not part of the offer.

Can I get a static IP address?+

A static IP is listed as available, and the service runs on fttp rather than a shared line. A fixed address helps anyone hosting services, connecting a VPN to the home network, or running cameras that need a stable destination. It is a detail that most household broadband pages leave out entirely.
