Openreach implemented its national stop-sell of Wholesale Line Rental (WLR) on 5 September.

This blog shares everything you need to know about Openreach’s WLR and PSTN switch-off including key dates, high-margin digital replacements to offer your customers, and how to gain an edge over the competition.

⭐ This is a live blog, updated as Openreach announces new information. Save it to your favourites.

🚩 We’ll highlight updates with a red flag so you can easily spot what’s new.

1. what’s Openreach’s WLR and PSTN switch-off?

The background

The UK is upgrading to digital.

Openreach is winding down the copper-based network that’s served the UK for over a century.

This is partly driven by the fact that the current infrastructure is running on equipment that’s reaching end of life – parts and skills are becoming scarce.

Openreach’s intention is to force a country-wide digital upgrade. That’s great news for pretty much everyone, because digital is better!

For any telecoms reseller that provides services that sit on Openreach’s Public Switched Telephone Network (PSTN), churn is guaranteed.

What products are affected by Openreach’s WLR and PSTN switch-off?

By the end of December 2025 traditional telephony will no longer exist.

This includes:

  • analogue lines – PSTN
  • digital lines – ISDN2 and ISDN30
  • any connectivity that relies on the old copper network – mostly made up of ADSL and FTTC broadband

Key dates for Openreach’s WLR and PSTN switch-off

From 5 September 2023 – no new WLR line orders will be accepted

From the 5 September 2023, no new WLR line orders will be accepted* by Openreach.

This includes adding a new ADSL or FTTC broadband service to an existing analogue line, as well as like-for-like transfers.

Existing WLR-based services will continue to function.

* Openreach has rules which permit some WLR orders in niche instances.

🚩 Updated – 16 August 2023

eve social post

In August 2023, just a few weeks ahead of the stop-sell deadline, Openreach announced a small change to the WLR Withdrawal programme, which provides a new exception.

In areas where neither FTTP nor SOGEA is available, representing approximately 5% of the UK, the option to choose ADSL via a WLR PSTN line will remain accessible until 28th March 2024.

This is to give Internet Service Providers (ISP’s) more time to consume the newly offered SoTAP / SoADSL option from Openreach, which bundles a copper pair with an ADSL signal, in the same way that SoGEA bundles a copper pair with FTTC as the broadband technology.

December 2025 – Openreach’s WLR and PSTN switch-off

At the end of December 2025, Openreach will switch off the WLR network.

All services need to be migrated off WLR before this date, or customers will lose service.

9 October 2023 – Salisbury and Mildenhall exchanges withdrawn

If you have customers in Salisbury or Mildenhall, their services need to be migrated sooner.

These are Openreach’s test exchanges, where WLR will be withdrawn on 9th October 2023.

🚩 Updated – 16 February 2023

The Salisbury and Mildenhall exchange withdrawals were originally due to take place by 19 April 2023.

The date has been moved back due to the number of end users still remaining on WLR being higher than expected.

Openreach has reflected:

  • In-scope end customers remaining on WLR is higher than expected
  • Channel partner feedback shows that end-customer engagement on messaging is hard
  • Learning is limited
  • Protection of vulnerable end customers

Openreach has confirmed they are adapting by:

  • Introducing batched service measures to prompt end-customer contact to channel partners
  • Applying FTTC speed reductions
  • Applying outgoing call barring
  • Keeping exemptions open

Timeline for service degradation measures at Openreach’s trial exchanges

🚩 Updated – 24 April 2023

To avoid service degradation, Communication Providers were informed that they must have in-flight orders for All IP products, or exemptions granted by Openreach.

First phase of service degradation – WLR with FTTC

21 April 2023 – Openreach wrote to affected Communication Providers who had WLR and FTTC assets in the trial exchanges.

They confirmed the affected assets, the planned service degradation timeline, and how to apply to have the service degradation measures removed.

27 April, 10 May, and 24 May 2023 – Openreach commenced the first phase of service degradation, which was performed in three batches. Bandwidth for FTTC with WLR was reduced to 2Mbps downstream and 0.8Mbps upstream (excluding Gfast).

Second phase of service degradation – WLR

1st June 2023 – Openreach wrote to all affected Communication Providers who had WLR assets in the trial exchanges.

They confirmed the affected assets, the planned service degradation timeline, and how to apply to have the service degradation measures removed.

7 June, 21 June, and 5 July 2023 – Openreach started the second phase of service degradation, re-routing outgoing calls to the Communication Provider who was providing the voice service. This occurred in three batches. Free phone numbers were excluded.

9th October 2023 – all services will be ceased no earlier than this date.

FTTP priority exchanges

🚩 Updated – 19 July 2023

Openreach has already implemented stop-sell of new WLR services at over 461 exchanges where FTTP is available at the premises connected to those exchanges.

It’s worth checking Openreach’s published list of FTTP Priority Exchanges to see if any are in locations where you have a concentration of customer sites.

🚩 Updated – 19 July 2023

Openreach has passed over 11 million premises for FTTP availability.

Have you checked if your customers can get FTTP? The speeds offered will remove speed issues and allow on-premises solutions to be moved into the cloud.


We must add that a wide range of other fibre networks are being built in addition to the Openreach project, taking the UK’s FTTP coverage to over 13 million premises.

These tend to be known collectively as ‘alt-nets’. Some are very regional, with the largest challenger brand being CityFibre, which has plans to pass 8 million premises by 2025.

Some alt-nets have a pure vertical sales model to the end customer. Others wholesale their networks so MSPs and IT resellers can have a range of networks and options in their kit bag.

2. the opportunity for MSPs and IT resellers

All telecommunications must move to all IP-based services before 2026.

All UK businesses, charities, local authorities and health providers need to review their communication links and voice services.

This creates a huge opportunity for MSPs and IT resellers to sell or upsell comms solutions. This ties in perfectly with the IT and cloud solutions you offer and support today.

eve Networks Managing Director talks to Louise Abbey about the opportunity, and how we’re treating this as a ‘switch-on’, rather than a ‘switch-off.’

Digital solutions to migrate your customers to all IP

Voice services will need to move off ISDN and PSTN services to hosted VoIP.

  • a pure cloud-hosted VoIP service where the service is just accessed on-site via a physical IP phone
  • an app running on a mobile, tablet or desktop with all the services delivered via the cloud
  • via SIP trunks if an on-site phone system / PBX remains the best customer solution. This can often be the case for hotels and schools, or anywhere there are lots of extensions to the number of simultaneous external calls happening.

Broadband connectivity needs to be decoupled from WLR lines and the 3 key services will be:

  • FTTP, if available to the site
  • SoGEA which is an FTTC variant but where the copper access service is bought as one combined product and has over 95% UK coverage
  • Fibre Leased Lines, which is a dedicated internet connection, where the end-user needs guaranteed bandwidth and a fix time service level agreement and is available nationwide 

A further broadband option is planned by Openreach for the sites that have neither SoGEA or FTTP available. SoTAP will support current ADSL speeds but with the copper integral as part of the service. SoTAP is currently in test, so these sites must be addressed later in the migration project off WLR.

4. other services affected by WLR

When you speak to customers about Openreach’s WLR and PSTN switch-off they may ask questions about other services they plug or connect into mainly analogue lines.

These are things like alarms, health pendants, payment terminals, and lines in lifts.

Other more obscure items may be lines used for controlling traffic lights or monitoring environmental aspects, like reservoir levels in the water industry.

Openreach has a helpful brochure on the All IP project, which includes detail on these areas.

6. Faqs

🚩Updated 18 April 2023

What does ‘All IP’ mean? 

Openreach’s All IP Programme refers to the telephony network in the UK being changed so that all services work over the Internet (IP or Internet Protocol).

Will the general public be informed about Openreach’s All IP programme?

There are around 650 Communication Providers operating in the UK.

Openreach has stated that it’s the Communication Providers’ responsibility to communicate with their customers about the migration to All IP. It’s presumed that they will give a responsible notice period.

The gov.uk website has recently been updated with a dedicated page to cover the digital switchover – UK transition from analogue to digital landlines

If a PSTN order is placed before 5 September 2023, but the installation hasn’t taken place yet, will the order be cancelled?

WLR stop sell applies to new orders placed from 5 September 2023. All orders placed prior to this date will be completed.

Will WLR be withdrawn in FTTP Priority Exchanges before December 2025?

WLR services will not be withdrawn until December 2025. Note that this doesn’t apply to the test exchange in Salisbury.

Will the WLR withdrawal date be extended?

Openreach has stated that there are no plans to extend the December 2025 deadline.

 In December 2025, will all existing services on PSTN be ceased, or will they be migrated to a service like SOGEA?  

All WLR lines have to be migrated to an alternative product such as SOGEA, by December 2025. Any WLR lines which have not migrated by this deadline will ultimately be ceased.

Will SOGEA eventually be replaced by FTTP? 

There are currently no plans for SOGEA to be replaced.

Is there a specific date in December 2025 when WLR will be withdrawn in the UK?

Openreach has said an exact date will be confirmed closer to the time.
