Pros and cons

Pros

  • Entry price of £18.50 a month, with a rank of 32 of 95 brands on price from.
  • Setup fees of £0 to £14.95 rank 1 of 86, so the one off charge to join is light.
  • Contract terms of 12 and 24 months let you trade a higher monthly price for a longer commitment.
  • A longer contract is the cheaper way to hold the higher speed, since the faster fibre plan costs less per month on the longer term.

Cons

  • Top speed of 67 Mbps is far below the 10,000 Mbps Abissnet and the 5,000 Mbps Astound advertise.
  • Prices rise each April while you are in contract, so the £18.50 entry price is not the price you keep paying.
  • Setup fees of £0 to £14.95 can push the first bill above the £18.50 monthly headline.
  • Contract terms of 12 and 24 months mean the cheaper monthly rate locks you in for the longer term.

Who it suits

  • Households in the UK that want low cost fibre and are content with a modest top speed.
  • Buyers who prefer a shorter commitment, since terms of 12 and 24 months are on offer.
  • Anyone ranking providers on entry price and setup fee first, where Onestream sits near the front on both.

Who should look elsewhere

  • Households that stream constantly or push large files, who should look at Abissnet at 10,000 Mbps or EarthLink at 5,000 Mbps.
  • Shoppers buying purely on headline speed, since Astound lists 5,000 Mbps against the 67 Mbps here.
  • Anyone budgeting the same amount for every month of the term, since prices rise each April in contract, while EarthLink at 5,000 Mbps suits speed first buyers.

How it compares on our data

Onestream lands in different places depending on what you measure, and the pattern matters more than any single line. On max download mbps it sits at 111 of 114 brands, the weakest of the measures here. On price from it reaches 32 of 95, which is far more competitive. Setup fee is the strongest showing, at 1 of 86. Taken together, that describes a provider you pay less to join and use for less speed.

Plans and prices

Onestream starts with its entry fibre plan at £18.50 a month. A faster fibre plan sits above that, and the same speed sold on a shorter contract costs more again, so the longer term is the cheaper monthly commitment. Setup fees run £0 to £14.95. Keep renewal in view too: £18.50 is the entry price rather than the long term one, and prices rise each April while you are in contract.

How Onestream compares

Frequently asked questions

What is the cheapest Onestream plan?+

The entry point is Onestream's cheapest fibre plan at £18.50 a month in the UK. That figure puts Onestream at 32 of 95 brands in our list on price from, a strong showing for a budget provider. Higher speeds on the same network cost more each month, so the cheapest plan suits lighter use.

How fast is Onestream broadband?+

Onestream tops out at 67 Mbps for downloads, which puts it at 111 of 114 brands on our speed ranking. That is plenty for browsing, video calls and streaming on a shared connection in a small home. It is not enough for a busy household running several streams at once.

Does Onestream charge a setup fee?+

Setup fees on Onestream run £0 to £14.95, so the amount you pay to join depends on the deal you take. On our list of 86 brands, Onestream ranks 1 on that measure, which makes it one of the cheaper providers to get started with. Check the fee before you order so you know what lands on the first bill.

How long is the Onestream contract?+

Onestream offers contract terms of 12 and 24 months, so you can take a shorter commitment or a longer one. On the faster fibre plan the longer term is the cheaper monthly deal, and the shorter term costs more each month for the same speed. Pick the length that matches how long you expect to stay put.

Does the Onestream price rise during the contract?+

Yes. Onestream states that prices rise each April while you are in contract, so the £18.50 monthly figure on the entry fibre plan is the starting price rather than the long term one. Budget for an increase each spring and factor it into any comparison with a provider that holds its price for the same period.

What broadband plans does Onestream sell?+

The reference list covers a basic fibre plan, a faster fibre plan and a shorter contract version of that faster plan. The basic plan is the cheapest of the set, the shorter contract version costs the most each month, and both faster plan options run at the same speed. Only the contract length and the monthly price separate them.

How does Onestream compare with faster broadband providers?+

For raw headline speed, Abissnet advertises 10,000 Mbps, Astound lists 5,000 Mbps and EarthLink lists 5,000 Mbps, all well beyond the 67 Mbps Onestream tops out at. Those are higher capacity lines for heavy use, while Onestream trades speed for a lower monthly price.

How does Onestream score overall?+

The overall score is 8.7, with the cost part at 9.4 and the offer part at 8.1. The cost rating reflects the entry price and the setup fee, both of which sit near the front of our list. Weigh the offer part against your own priorities before you commit to a contract.
