Zen Internet Fibre Broadband Deals (April 2026)

Zen Internet Full Fibre broadband starts from around £33/month for the Full Fibre 100 tier, rising to approximately £50/month for Full Fibre 900, on 18-month contracts. Zen holds a Which? Recommended Provider badge (84% customer score in 2026), is B Corp certified, and operates a no-mid-contract-price-rise policy. Zen uses both Openreach and CityFibre FTTP networks, with free setup on CityFibre and £15 on Openreach.

Zen Internet Full Fibre Package Prices in April 2026

Zen Internet's April 2026 Full Fibre range spans: Full Fibre 100 (~100Mbps down, 18Mbps up) at £30–35/month; Full Fibre 500 (~500Mbps) at £36–42/month; Full Fibre 900 (~900Mbps, minimum 450Mbps) at £42–50/month; and Full Fibre Max (1,600–2,300Mbps) at £56–65/month on Openreach ultrafast FTTP. Prices vary by network — Openreach and CityFibre pricing differs slightly by postcode. Zen also discounted Openreach FTTP prices in February 2026 — for example, Full Fibre 500 on Openreach dropped to £39/month. 18-month contracts are standard. No setup fee applies on CityFibre; a £15 setup fee applies on Openreach. Legacy FTTC packages (Unlimited Fibre 1 at 36Mbps for £33/month; Unlimited Fibre 2 at 78Mbps for £37/month) remain available for FTTC-only addresses. BT's Full Fibre 900 is £48/month — comparable to Zen's top tier, but without the fixed-price commitment or Which? award backing.

Zen Internet's Fixed Pricing and Speed Guarantee

Zen's key differentiator is price certainty: it does not apply mid-contract price rises. When the major ISPs raised prices by £3–4/month in April 2026, Zen customers on existing contracts were unaffected. Zen also offers a speed guarantee — if your connection falls below the minimum guaranteed speed at signup, Zen will investigate, fix the issue, or release you from contract without penalty. This is more stringent than the minimum speed guarantee offered by mass-market providers like Plusnet or Cuckoo. Every Zen package includes a free router and a static IP address — a feature typically chargeable at other ISPs. Typical latency on Zen's FTTP is 5–10ms to UK servers, with sub-10ms gaming pings consistently reported by users.

Zen Internet and FibreHop: The 2025 Acquisition

In September 2025, Zen Internet acquired the consumer broadband base of FibreHop — a small ISP that had built a following selling CityFibre broadband at £26–£46/month with no mid-contract price rises. The FibreHop acquisition expanded Zen's CityFibre customer footprint and is consistent with Zen's strategy of growing on the CityFibre alternative network. FibreHop customers were migrated to Zen contracts, with Zen honouring the no-price-rise commitments. This positions Zen as one of the largest ISPs on CityFibre alongside Vodafone and TalkTalk. Zen's Full Fibre Max (1,600–2,300Mbps) is available in select Openreach ultrafast and CityFibre multi-gigabit areas, with pricing from £56/month.

Is Zen Internet Worth the Premium?

Zen costs more than mass-market providers: its Full Fibre 500 is around £39–42/month versus Plusnet's equivalent at £27.99/month. The premium buys a genuinely fixed price, a stronger speed guarantee, a static IP, 100% UK support, and a B Corp certified ethical structure. Which? rated Zen at 84% in their 2026 broadband provider survey — the highest of any nationally ranked provider. For households that have been burned by unexpected mid-contract price hikes, or businesses that need reliable home broadband, Zen's proposition is compelling. For purely price-conscious customers who are comfortable managing issues online, Plusnet or TalkTalk offer better cost-per-megabit value. The average UK broadband bill of £35.90/month (Ofcom 2025) sits below Zen's entry price — a reflection of the premium service quality on offer.

Frequently Asked Questions

Does Zen Internet have fixed prices?

Yes. Zen Internet does not apply mid-contract price rises during your 18-month contract term. This is one of its most prominent selling points, particularly since BT, Sky, EE, TalkTalk, and Vodafone all raised prices by £3–4/month in April 2026. After your contract expires, Zen may apply rises, and these will be stated clearly in your new contract at renewal.

Is Zen Internet a Which? Recommended Provider?

Yes. Which? awarded Zen Internet a Recommended Provider badge based on its 84% customer satisfaction score in the 2026 survey — the highest rating of any provider covered in the national survey. Zen has consistently appeared in the top tier of Which? rankings for multiple consecutive years.

What is Zen Internet's minimum contract length?

Zen Internet's standard contract is 18 months. 12-month options are available on some plans. Zen does not typically offer monthly rolling contracts for broadband — customers wanting a no-contract option might consider Cuckoo, which offers rolling monthly plans on FTTP via CityFibre at a similar premium tier.
