PSTN Switch-Off 2027 for UK Hotels, B&Bs and Guesthouses (2026 Guide)

Last updated: April 2026

UK hotels, B&Bs and guesthouses have more PSTN-dependent services than most realise — and you need a migration plan before the 31 January 2027 switch-off. Room phones, reception lines, fire and intruder alarms, lift phones, payment terminals, some older key-card systems.

Here's what to do.


What's affected in a typical hotel

Front-of-house

  • Reception / booking phone line (often a rotary of multiple lines with hunt group)
  • Restaurant / bar phones
  • Conference / events phones
  • Payment terminals if using older dial-up modems

Guest rooms

  • In-room phones — often PSTN via internal PBX from one main PSTN line
  • Fire alarm integration — some older in-room alarm systems signal via PSTN

Back-of-house

  • Fire and intruder alarm monitoring circuits — usually on dedicated PSTN lines with monitoring company
  • Lift emergency phones — legally required (BS EN 81-28), typically PSTN
  • Building management systems — HVAC, boiler monitoring, CCTV callbacks
  • Key-card systems — some older integrations use PSTN callbacks for alarm conditions

Connectivity

  • Fax if still used (rare in modern hotels but some international customer patterns still do)
  • EPOS integration — some older till systems dial out for stock alerts

For a typical 30-bedroom hotel, that's often 5-15 separate PSTN-dependent services. All need migration.


Replacement options

Reception and common-area phones

Cloud VoIP handles all of this. Hunt groups (multiple lines ringing in sequence), auto-attendants, call queuing, restaurant/bar direct-dial extensions — all native in modern VoIP platforms. Typical setup £15-25 per extension per month on 36-month contracts.

Guest room phones

Three options:

  1. Full cloud VoIP to rooms — requires cabling update (Cat5e/6 to rooms), more expensive install but modern and flexible
  2. Replace guest phones with VoIP-capable handsets on existing cabling — works if existing wiring supports it
  3. Remove in-room phones entirely — increasingly common for budget hotels and B&Bs where guests use own mobiles; provide instructions at reception for emergencies

Decision depends on hotel type. Boutique and high-end hotels generally keep in-room phones for service; budget / serviced apartments often remove them.

Fire and intruder alarms

Switch to IP-based alarm monitoring via your existing alarm company. BT Redcare IP, CSL DualCom IP, and similar products are all available. Cost similar to existing PSTN monitoring, sometimes slightly cheaper. Fire alarm migration requires competent installer — not a DIY job.

Lift emergency phones

Legally required under BS EN 81-28. GSM-based lift phone upgrades installed by lift maintenance company, typically during scheduled maintenance. Cost £300-800 installation + £10-30/month monitoring.

Payment terminals

Most modern card terminals are IP-based or 4G already. Any still on dial-up need replacement. Contact your card provider (Worldpay, Elavon, Adyen, Tyl by NatWest) for their IP-based replacement units.

Building management

Varies by system. BMS providers have been upgrading through 2022-2026. Ask your BMS maintenance company for a status check.


The hotel-specific timing challenges

Hotels don't have "quiet periods" — peak season, off-peak means lower occupancy but never empty. Migration timing considerations:

  • Avoid peak season migrations — do it in January-March or October-November rather than summer/Christmas
  • Test outside hours — VoIP commissioning ideally 11pm-6am to avoid guest disruption
  • Plan for failure — keep mobile backup for reception during the VoIP cutover window
  • Coordinate with fire alarm testing — required checks shouldn't overlap with migration
  • Lift availability — lift phone migration can temporarily take lifts out of service; coordinate with maintenance

Cost estimates

Indicative for a 30-room UK hotel:

  • Cloud VoIP for all public areas (reception, bar, restaurant, conference): £300-500/month
  • In-room VoIP (if retaining in-room phones): additional £150-300/month depending on handset choice
  • Fire alarm IP migration: one-off £500-1,500 installation + existing monthly monitoring fee
  • Lift phone GSM upgrade: £500-1,000 per lift + monitoring fee
  • Payment terminal replacement (if required): £200-500 per terminal
  • Project management and coordination: depends on complexity

Total outlay for 30-room hotel commonly £5,000-15,000 one-off plus ~£400-800/month ongoing (often lower than existing PSTN costs once consolidated).


FAQs

Does every hotel room phone need replacing?

Depends on how rooms are currently served. If you have in-room phones on a traditional PBX connected to PSTN, yes — either the PBX migrates to cloud VoIP (with in-room phones potentially re-used if compatible) or in-room service moves to VoIP entirely. Some hotels are using the switch-off as a reason to remove in-room phones altogether.

Does my hotel's fire alarm really need migration?

If the alarm monitoring circuit (the connection between your fire panel and the monitoring company's receiving centre) is on PSTN, yes. Your fire alarm panel itself doesn't need replacing — just the signalling connection. Check with your fire alarm maintenance company.

Can I remove in-room phones entirely?

Legal for most hotels — no specific regulation requires in-room phones. However: (1) some star-rating schemes (AA, VisitBritain) include in-room phones as criteria; (2) some insurance policies may have implications; (3) some guest segments (older, business travellers) expect them. Consider your specific market before removing.

What about lift phones in my small guesthouse without lifts?

Not applicable. Lift emergency phones are only required in buildings with passenger lifts. If your property has no lifts, you can skip this.

Does the PSTN switch-off affect my WiFi broadband?

Depends on your broadband technology. Traditional ADSL used PSTN lines — these are being replaced with FTTC and full-fibre equivalents. If your hotel broadband is already FTTC / fibre, it's unaffected. If still on ADSL, it migrates to a digital equivalent.
