Get £20 off Onestream broadband
The Onestream link and code on this page are referral links. If you sign up with one, I also get a £20 bill credit, at no extra cost to you. Onestream does not choose what I say about it.
Onestream Limited is a broadband provider based in Whiteley, Hampshire. It sells part-fibre broadband and full-fibre, which it calls TrueFibre, up to 900Mb a second. New broadband lines come without a landline, though you can add home phone and calls.
Onestream says it has more than 25,000 five-star reviews. You sign up online, and Onestream handles the switch, so you do not need to call your old provider.
The credit comes off future bills and cannot be paid out as cash. It only applies to new customers who have not been with Onestream in the last six months. Sign-ups through comparison sites do not qualify, because there is no place to add the code.
To see how Onestream compares with nine other providers over a full contract, read our guide to cheap broadband deals in the UK.
The deal prices are for new customers. Onestream's price guide lists much higher standard monthly charges, such as £34.95 for Fibre 40. Check what you will pay once the minimum term ends, and set a reminder to switch or renegotiate.
Leaving during the minimum term can cost you. If Onestream arranged an installation, its terms say you pay the full activation fee if you leave early.
The £20 only reaches your bill after the broadband is live, and only if your order completes.
Onestream sells direct from its website. The full rules are in Onestream's refer a friend page, and Ofcom explains your rights when you change provider in its guide to switching broadband.
