Brighton Businesses: PSTN Switch-Off Deadline December 2027

Every Brighton and Hove business still using traditional landlines or ISDN must migrate to VoIP by December 2027. Openreach is switching off the UK's PSTN network — businesses that don't migrate will lose phone service. T2K VoIP specialises in zero-downtime migrations for Brighton businesses, keeping your 01273 numbers while moving to modern VoIP.

Brighton's Business Landscape & VoIP Requirements

Brighton & Hove's economy spans a world-class digital and creative tech sector ('Silicon Beach'), thriving tourism and hospitality, education, and professional services. Each sector has specific telephony needs — T2K understands the unique, vibrant demands of the city's business environment.

Known as the unofficial capital of the South Coast, Brighton & Hove is home to over 14,000 businesses. The city is highly celebrated for its 'Silicon Beach' digital cluster, which houses hundreds of innovative tech startups, software developers, and creative agencies requiring ultra-fast, cloud-based communications and seamless hybrid working capabilities.

Brighton businesses moving from ISDN to VoIP need partners who understand both the city's fiercely independent spirit and the technical requirements of a seamless migration. T2K VoIP has deployed systems across all Brighton and Hove business districts — from agile digital agencies in the North Laine to established professional firms operating in central Hove.

FAQ

VoIP for Brighton Businesses — Frequently Asked Questions

Questions we regularly hear from Brighton & Hove businesses evaluating VoIP systems.

Can I keep my Brighton 01273 phone numbers when switching to VoIP?
Yes. All Brighton and Hove 01273 numbers can be ported to VoIP with no gap in service. T2K VoIP manages the full number porting process — your clients and customers continue calling the same 01273 numbers from day one. This applies to all six systems we deploy.
Do you provide on-site support for Brighton businesses?
T2K VoIP provides remote support for all Brighton deployments, with on-site visits available when required (e.g. for complex multi-site installations or hardware troubleshooting). Most issues are resolved remotely, but we can easily attend Brighton, Hove, and Sussex sites when necessary. We also work with trusted local engineers across the South Coast for rapid on-site response when needed.
What's the typical cost for a Brighton business to switch to VoIP?
For most Brighton SMEs (5–50 users), expect £10–£20 per user per month for hosted platforms like Gamma Horizon or 3CX. Larger Brighton businesses or those with specific requirements (multi-site, contact centre, resilience) typically use Mitel with custom pricing. T2K provides transparent quotes with no hidden fees. Many Brighton businesses see a 30–50% cost reduction vs their old ISDN lines.
How long does a VoIP migration take for a Brighton business?
Single-site Brighton businesses (under 20 users) typically migrate in 1–2 weeks from initial consultation to go-live. Multi-site Brighton & Hove deployments (e.g. offices in the City Centre, the Marina, or across Sussex) take 4–8 weeks depending on complexity. T2K schedules cutovers for evenings or weekends to minimise disruption. Most Brighton businesses experience zero downtime during migration.
