What this means if you’re on the Highams Park exchange
Openreach places an exchange on the FTTP priority list once full fibre reaches roughly 75% of the premises it serves. From the restriction date, any premises here that can order full fibre can no longer take out new copper services — analogue phone lines, FTTC broadband, working-line takeovers. Nothing is switched off on that date: existing lines keep working until your provider migrates you ahead of the national PSTN retirement on 31 January 2027.
When migration happens your number stays the same — local landlines here use the 020 dialling code for London, which is unaffected by the switch-off. If a call from an unfamiliar local number is what brought you here, run it through the lookup to see the Ofcom range holder and live reputation reports.

FAQs about the Highams Park exchange
Is the Highams Park telephone exchange closing?
Highams Park (code LNHPK) is on Openreach's FTTP priority stop-sell list — copper sales restrictions have applied since 16 February 2024. The building isn't shutting yet, but analogue (PSTN) service ends nationally on 31 January 2027, and premises with full fibre available here can no longer order new copper products.
What does stop sell at Highams Park mean for my landline?
Existing services keep working — stop sell only blocks new supply of copper products (new analogue lines, copper broadband, transfers between providers on copper) at premises where full fibre is available. When your provider migrates you, your phone number stays the same and calls move to digital voice over broadband.
Which numbers come from the Highams Park exchange?
Highams Park serves the London area, where landlines use the 020 dialling code. Bear in mind UK numbers are portable, so a 020 number no longer proves a physical line on this exchange — use the lookup to check any specific number.
