Zen Internet Contract End & Renewal Guide 2026

How long are Zen contracts?

On zen.co.uk itself, home full fibre is currently sold on 18-month minimum terms. ISPreview's February 2026 reports on Zen's price cuts list every tier at 18 months with free setup: on Openreach, 105Mbps £33, 500Mbps £39, 910Mbps £45 and 1.6Gbps £56 a month; in CityFibre areas, 155Mbps £28, 500Mbps £34 and 910Mbps £39. Comparison sites also list 24-month deals — the full picture is on the packages guide. Uswitch says 12-month terms “may be available” if you ask Zen directly. Ofcom caps consumer broadband contracts at 24 months. One detail from the terms: the contract term starts on the day your service is activated (clause 2.1), not the day you ordered.

How do I find my contract end date?

Log into My Account: your service details show the term, and once it's passed the service is labelled “Out of contract”. Zen also has to tell you. Ofcom's rules, in force since 15 February 2020, require an end-of-contract notification 10 to 40 days before the term ends, by text, email or letter, stating the end date, the notice period for leaving, what you pay now, what you'll pay afterwards, and the provider's best deals including any prices reserved for new customers. If you stay out of contract, an annual best-tariff reminder follows.

What happens to the price when I'm out of contract?

Your service moves onto a rolling monthly contract (clause 2.4). The Consumer Price Promise in clause 14.1 fixes your monthly charge during the term, then says Zen may increase your monthly charges at the end of the term by giving at least one calendar month's notice. After that, clause 14.2 allows further price changes outside a fixed term, again with notice. Zen's Contract Price Promise page puts it as a “minimum of 30 days' written notice” for “reasonable increases”. So an out-of-contract rise isn't automatic, but it's explicitly on the table, and what's guaranteed is the notice, not the price.

The legacy exception: contracts that started on or before 31 May 2022 keep Zen's old Price for Life, even out of contract, as long as you stay on the same package at the same address. If that's you, staying out of contract can be the better deal. Full detail on the price rises page.

What I can't tell you is how much. Zen doesn't publish an out-of-contract price list or a typical uplift, and I won't guess. Whatever the figure, it has to be on your end-of-contract notice.

Do existing customers get the new-customer price?

Usually, by re-contracting. Zen's Contract Price Promise FAQ says that at the end of your term you can stay out of contract or “take out a new contract on the same or another package”, and that a new contract fixes the price again. When Zen cut its CityFibre prices in February 2026, ISPreview checked and reported: “Zen has confirmed that existing customers who are out of contract can re-contract at the new price.” Its Openreach report the same month says Zen “does normally allow” the same.

The caveat is the comparison-site channel: Uswitch's Zen page warns its deals “may not be available to existing customers”. My reading is that existing customers can generally match the direct zen.co.uk price for a package, but not necessarily every third-party promotion. Ask, and ask about the tier below yours too.

How to re-contract

Read the end-of-contract notice properly; it has to list Zen's best current tariffs.
Run your postcode through zen.co.uk and note the direct price for your current tier and the ones either side of it.
Contact Zen (customer services, or through the portal) and ask to re-contract at the advertised price for the package you want. Once you're out of contract, the mid-term regrade rules in clause 15 no longer bite, so downgrading is straightforward.
Get the new term length and monthly price in writing. From then on the Contract Price Promise fixes it.

Negotiating: what's realistic

I haven't found any published evidence of a Zen retention team offering unadvertised discounts, and Zen's whole pitch is that the advertised price is the price. So treat the direct price on zen.co.uk as the realistic floor and use these levers instead:

Drop a tier. The gap between 500Mbps and 910Mbps is real money over 18 months and most households won't notice the difference.
Time it to a price cut. Zen cut its Openreach and CityFibre full-fibre prices in February 2026; if you were mid-term you couldn't take advantage, but out of contract you can.
Be genuinely willing to leave. One Touch Switch makes it painless and the notice itself has to state your notice period. Don't bluff — see how cancelling works so you know the real alternative.
If speed has been below the guaranteed minimum, that's a clause 9.1 right to leave without penalty, not a bargaining chip, but raise it.

The £40 referral is not a renewal tactic

To be completely clear: the refer-a-friend eGift card is for new Zen customers only — people who have never had a Zen account under any email address. If you're at the end of a Zen contract, the referral link on this site does nothing for you, and cancelling to rejoin under a different email is outside the offer's terms, so don't. What you can do is the reverse: refer someone else with your own link from Zen's refer-a-friend page and collect the referrer's reward yourself. The other reasons people leave at contract end are covered on the moving house and cancellation pages.
