Zen vs BT for business broadband.
Zen’s service reputation versus BT’s scale. Telexico supplies both — here’s an honest comparison.
Providers are compared on what each publishes: list prices and the conditions attached to them, minimum terms and mid-contract rises, what the price includes (calls, set-up, porting, support hours), UK-based support, and whether failover is offered. Telexico’s own entries are our list prices. Where a provider has changed its terms since the date shown, the published source wins; tell us and we will correct it.

What BT Business’s published terms say.
Quoted or closely paraphrased from BT Business’s own terms, prices and published pages on the dates shown, with a link under each point. Clauses change: read the version attached to your own order before relying on anything here.
Minimum term
Business broadband deals are sold on “24-month contracts”, with “standard prices apply from month 25”. BT Cloud Voice licences are priced “a month per 60 month licence”; no shorter term is shown on the page.
SourceThe April rise, in writing
For contracts taken from 2 December 2024, prices rise every 1 April by a fixed sum: broadband and digital phone line bundles +£4 a month, broadband only +£3, Cloud Voice +£1 per licence, Digital Voice +£1 per user. Older contracts keep CPI + 3.9%.
SourcePublished prices
Cloud Voice Basic £10.52, Connect £13.74, Collaborate £20.09 a month per 60-month licence; Digital Voice for Business £15, £18 and £21 per user a month (ex VAT). Broadband pages show a percentage off rather than a price.
SourceSupport
A “dedicated 24/7 UK-based helpdesk”, broadband faults targeted “within seven working hours”, contact by phone, chat and WhatsApp. A named account manager is not mentioned on the SME pages.
SourceReviews and complaints
Trustpilot “BT Business”: 3.7 out of 5 from 16,214 reviews (56% five-star, 32% one-star). Ofcom’s Q1 2026 complaints data put BT fixed broadband at 7 complaints per 100,000 customers against an industry average of 6.
SourceWhat BT genuinely has
Openreach and EE under the same roof, a published price-rise schedule years ahead, EE 4G Hybrid Backup on Enhanced plans and a national engineering footprint.
The notice window is the whole game.
BT’s SME pages do not state a notice period or an auto-renewal rule, so your order form and the terms attached to it are the only reliable source: find the end date, the notice required and whether anything renews. Then tell us the date; the switch is planned to land inside your window, numbers ported, nothing switched off early.
Tell us your end date →Months away? The date goes into the director’s diary and we come back before the window closes, with a written quote to compare against the renewal.
Four things that are the same on every Telexico agreement.
Rolling 30-day terms, or 12 months where handsets are included; the term and the notice period are written on the first page of the proposal. There is no automatic renewal clause: when a term ends you stay on 30-day rolling, nothing re-ties you for another year.
The per-user price you sign is the price for the term. There is no April uplift clause in a Telexico agreement.
Numbers port across on an agreed date, the new system runs alongside the old one until it is tested, and nothing is switched off early.
A named engineer and account manager from Wolverhampton, a WhatsApp group for your team, and a UK phone line answered by people who know your sites.
Trustpilot score shown for BT Business: 3.7 out of 5 from 16,214 reviews on 14 October 2026 (Trustpilot). Telexico is a competitor; judge the points above on the documents linked, not on us.
