Onestream broadband review 2021

By Dan Howdle | Tuesday, February 2nd 2021


Onestream broadband launched in the summer of 2018, and it’s part of the Hampshire-based broadband specialist Onecom. Like most UK broadband providers, it uses the Openreach network (see our broadband jargon guide for more information).

Onestream is one of a number of companies hoping to lure customers away from the ‘big four’ providers, BT, Sky, Virgin Media and TalkTalk. But is Onestream broadband any good?

Broadband speed

Onestream offers three fibre broadband deals. The cheapest is Jetstream Fibre Unlimited Broadband, which is a highly unusual fibre package. With average speeds of 17Mbps, it sits somewhere between the average 10Mbps speeds of ADSL broadband and the 36Mbps or so speeds of the cheapest fibre broadband packages offered by most other UK providers. It’s the slowest fibre option we’ve seen, but it could be a good budget option for customers who feel ADSL broadband is too slow but who don’t need particularly fast internet (take a look at our guide to see what broadband speeds you might need).

Then there’s Jetstream Fibre Max Unlimited Broadband, with an average download speed of 45Mbps and an average upload speed of 8Mbps. Most other providers offer something around this speed level. This speed is perfect for those who have multiple devices connected to the internet simultaneously and especially for families streaming Netflix or iPlayer to more than one TV, laptop or smartphone at any one time.

Finally, Onestream’s Xstream Superfibre Unlimited Broadband promises average download speeds of 67Mbps and upload speeds of around 17Mbps – that’s about as fast a broadband speed as most people will be able to get from any UK provider other than Virgin Media, which runs on a different network and is substantially faster.

Installation and router

Onestream uses the same network as BT, Sky, TalkTalk and pretty much every other national provider in the UK except for Virgin Media. Because of this, if you sign up with Onestream you won’t have to inform your old provider that you’re switching broadband – Onestream will do this for you. Unless you’re currently with Virgin, in which case you will have to do it yourself.

Onestream doesn’t specify how long it will take to get your broadband up and running, but you can generally expect a new provider to have activated your service within a couple of weeks.

You’ll get step-by-step instructions to get things set up at home (standard installation is free) although you do have the option of getting an engineer to come out to do it for you – as long as you’re willing to pay extra.


There’s the promise of a free ‘Super Dooper Router’ with all three of Onestream’s broadband plans. Onestream doesn’t say what router it uses, but as a general rule, the standard of routers given away by broadband providers has improved dramatically in recent years.

There’s no reason to think the ‘Super Dooper Router’ wouldn’t provide you with the choice of either a solid wireless connection or a faster and even more stable one via an ethernet cable.

There is a £9.99 charge for ‘secure delivery’ of the router.

Specific figures for Onestream are hard to come by as it is such a new provider, and it isn’t included in Ofcom’s research because its market share is too small. But there are figures available for Openreach, which is in charge of the network that Onestream runs on.

Openreach says it fixed 95.6% of faults within four working days in the second quarter of 2018 and that an average of 3,300 fewer faults were reported compared to the same period in 2017.

It’s unclear whether Onestream uses traffic management (prioritising one set of online activities over another, for example email over streaming) but there are no download limits on any of its packages.

Customer service

You can call up Onestream’s customer service team or email them you have any problems. They also offer a live-chat function during office hours. Onestream’s parent company Onecom has a good a good reputation in the business broadband market, but reports of customer service for Onestream consumer broadband are mixed. As of January 2021, Onestream had a 3.8/5 rating on Trustpilot, with 50% of 1,788 reviews rating them as ‘Excellent’ and 33% rating them as ‘Bad’.


Onestream is still something of an unknown quantity because it’s so new, but its parent company Onecom is well respected as a business broadband provider so that’s something to take comfort in.

Onestream offers one of the cheapest fibre broadband deals going with Jetstream Fibre Unlimited, but this package provides much slower speeds than other fibre broadband providers, so the savings might not be worth it if you’re in need of speedier internet. But on the positive side, the company has reduced its contracts from 24 months to 18 months, and its mid- and high-tier packages offer very competitive rates. Still, because of its budget-priced offering, don’t expect many extras from Onestream broadband packages. Head this way to check out the latest fibre broadband deals.
