PSTN / ISDN Switch Off

Openreach PSTN / ISDN Switch Off Support

Openreach have been advertising the big PSTN and ISDN switch off for years, which is now scheduled to happen in January 2027 (previously this was December 2025).  In order to prepare for this change, we have been helping many of our clients update their services to VOIP (Voice Over Internet Protocol) to make their business “future proof” in line with the changes. 

We have found that many businesses have accelerated their need for a more flexible telecommunication system (including remote working for example), and this is now our biggest incoming enquiry at present.  Should you have ISDN and PSTN lines currently in place, you should be able to continue using these services until January 2027 (area dependent), but you may be restricted in making changes to your existing setup.

There will be a number of cost and service benefits by doing an audit of your existing set-up now, and we would recommend calling us directly on 01565 755600 for some advice.  The changes will impact telephone systems, broadband service, fax (if still in use), point-of-sale terminals, redcare/dial-up alarm services and lift lines, for example.

How We Can Help?

We advise thousands of businesses across the UK (ranging from single site businesses, to those with hundreds of sites) and would hope to help your business in a similar way (in terms of both a cost and time saving).  What sets us apart is the way we work.  Our services are performance related.  This means that we share any refunds and savings realised for a predefined period, which arise as a result of recommendations, that we have implemented.  We act as independent advisors, helping your business secure the best services and contracts.

Please contact us today on 01565 755600 or send an e-mail to, and we will get back to you. 

As we approach the January 2027 deadline, there are likely to be further changes announced by Openreach, and it’s an area we have a lot of experience in, over the past 20 years.
