Does PSTN switch-off affect small UK independent shops?

Yes if you have shop phone line, intruder alarm with monitoring, card terminal, lottery/PayPoint terminal, or any dial-out service (refrigeration, HVAC). Check each for PSTN dependency. Many migrations happen automatically through suppliers; some need customer action.

Will my card terminal stop working after PSTN switch-off?

Only if it's an older dial-up PSTN terminal. Most UK card terminals installed in the last 5-8 years are IP-based (broadband or 4G) and unaffected. If yours is older, contact your card provider — replacement is usually free as part of PSTN migration.

Does National Lottery use PSTN?

Historically yes; most UK lottery terminals have been migrated to IP by Allwyn (current operator). Verify with Allwyn directly if in doubt — they've been coordinating upgrades on their programme.

How much does PSTN migration cost a typical small retailer?

Often cost-neutral or slightly positive. Cloud VoIP and IP alarm monitoring usually cheaper monthly than existing PSTN services. One-off installation costs small (£0-200 typically). Main 'cost' is coordinating with multiple suppliers.

PSTN Switch-Off 2027 for UK Independent Retail (2026 Guide)

Last updated: April 2026

UK independent retailers — convenience stores, newsagents, independent fashion and gift shops, hardware stores, post office branches, independent off-licences — often have more PSTN-dependent services than appears at first glance. Shop phone, intruder alarm, fire alarm, payment terminals, lottery/scratchcard machines, cash collection alerts. All need attention before 31 January 2027.

What typically needs migrating

Shop phone line

Reception / main shop number. Usually one or two PSTN lines. Replace with cloud VoIP — typically £15-25/month for a small shop. Works on a desk phone or softphone app.

Intruder alarm

Dial-up PSTN signalling from alarm panel to monitoring company. Migrate to IP-based signalling via your alarm provider. Cost similar or slightly cheaper than existing PSTN monitoring.

Fire alarm (if monitored)

Smaller shops usually don't have monitored fire alarms (just local sounders). Larger independents with stockrooms may. If you have fire alarm monitoring via PSTN, migrate with your fire alarm company.

Payment terminals

Most modern Chip & PIN terminals are IP or 4G. Any still on dial-up PSTN need replacement. Contact your card provider (Worldpay, Elavon, Tyl by NatWest, Barclaycard). Most are IP-based already; if yours isn't, ask for replacement.

Lottery terminals

National Lottery / Allwyn Entertainment terminals have been migrated progressively. Most independent retailers with terminals should be on IP already. Verify with Allwyn if unsure.

Scratchcard / Camelot terminals

Similar — mostly migrated. Verify.

PayPoint / Post Office terminals

PayPoint terminals migrating to IP per their scheduled programme. Post Office branch terminals: similar, coordinated through Post Office Ltd.

Cash machine / ATM (if on premises)

ATMs generally have their own communications arrangements (mobile, IP). The ATM operator (Cardtronics, NoteMachine, local bank) handles this — confirm with them.

Cash collection alerts

Some cash-handling safes and secure cabinets use dial-up callbacks to security companies to report openings or tamper. Check with your cash-in-transit provider.

What to do now

If you're a small independent (1 location, under 5 staff)

Quickest migration path:

Shop phone → simple VoIP service with one handset, £15-25/month, installed in 1-2 weeks
Alarm → one phone call to your alarm monitoring company, they schedule IP signalling upgrade
Payment terminal → if not already IP, one phone call to card provider for replacement
Lottery / PayPoint → verify with terminal provider

Total effort: 2-4 hours of phone calls, maybe a site visit for alarm upgrade. Costs often lower monthly than existing PSTN setup.

If you're a multi-site retail group (5-50 shops)

More complex. Consider:

Central coordination — single project plan across all sites
Consolidated supplier — moving all phones/alarms to one VoIP provider simpler than site-by-site
Phased rollout — migrate a few shops, resolve issues, scale
Staff training — new phone systems need brief induction
Avoid peak trading — don't migrate in December

CTN can quote multi-site migration as a package.

Hidden PSTN dependencies retailers miss

Intercom / door entry

Some older staff-only door intercoms dial out on PSTN for identification. Check with building owner if in a shared property.

Refrigeration monitoring (food retail)

Some older chilled/frozen display monitoring systems use dial-out on PSTN to alert on temperature failures. Critical for food safety. Check with refrigeration maintenance.

Fuel station dispensers (forecourt retail)

Fuel pumps communicate to till systems via various methods; some legacy installations have PSTN elements. Fuel retail systems providers (Suresite, Fairbanks, Gilbarco Veeder-Root) handle these migrations.

Air conditioning / HVAC

Some commercial A/C systems alert on failure via dial-out. Check with maintenance provider.

Security shutter remote controls

Some have PSTN callbacks for remote monitoring or operation alerts. Check installer.

Cost expectation

For a typical single-shop independent retailer:

Shop VoIP line: £15-25/month (vs £30-50 for PSTN line with calls)
Alarm IP signalling: similar cost to existing
Payment terminal replacement (if needed): usually no cost via provider
Project cost: £0-200 for installer visits
Ongoing saving: often £10-30/month cheaper than existing PSTN setup

Switching is often cost-positive long-term.

FAQs

Does PSTN switch-off affect my small shop?

If you have any of: a shop phone line, an intruder alarm with monitoring, a card terminal, a lottery terminal, a PayPoint machine — then yes, check each service for PSTN dependency and plan migration. Many have already been migrated by providers without you noticing; others may still need attention.

Will my card terminal stop working in January 2027?

Only if it's an older dial-up PSTN terminal. Most modern UK card terminals are IP-based (use broadband or 4G). If yours was installed in the last 5-8 years, almost certainly already IP. If older, contact your card provider for replacement — usually free of charge as part of PSTN migration.

Does my National Lottery / Camelot terminal use PSTN?

Work through a list: (1) current phone provider for shop line migration to VoIP, (2) alarm monitoring company for alarm signalling IP migration, (3) card provider for payment terminal check, (4) lottery/Camelot if applicable, (5) any other dial-out services (refrigeration, HVAC, door entry).
