PDSL — the Pre-Digital Phone Line, explained honestly
Rated 5 stars by 271 business customers on Trustpilot.
What is a PDSL?
PDSL stands for Pre-Digital Phone Line. When the analogue copper network is withdrawn in January 2027, most phone lines are expected to have moved to digital services carried over broadband. A PDSL exists for the lines that haven’t: it’s an analogue-style service that keeps basic calls working past the deadline, so the phone on the desk doesn’t simply go quiet.
Think of it as the industry’s waiting room. It buys time for businesses that miss the deadline or genuinely can’t move yet — and it does that one job well. What it isn’t is a destination: the digital migration it postpones is still waiting at the end of it, on a timetable the network sets rather than you.
When a PDSL genuinely makes sense
- Equipment that only speaks analogue. Some alarms, lift lines, telecare units and legacy card machines are certified against an analogue line and can’t be re-certified quickly.
- Premises in transition. A site you’re leaving, selling or refitting, where investing in a digital move makes no sense.
- No usable broadband yet. A digital line needs a working broadband connection; where one isn’t available yet, a PDSL bridges the gap.
- You missed the deadline. If January 2027 arrives and nothing was arranged, a PDSL is what keeps calls alive while a proper decision gets made.
If one of those is you, we’ll supply a PDSL and set it up properly. But notice what’s missing from that list: “I want to keep my analogue line.” For that, there’s a better answer below — cheaper, longer, and on your timetable.
What a PDSL doesn’t do
A PDSL is deliberately minimal. It carries basic voice calls and not much else — the features, the flexibility and the pricing all reflect a service designed to be temporary. It runs at retail-level line rental (typically £25–£40+ a month from major providers), the network decides how long the bridge lasts, and when it ends you face the same digital migration you face today — just later, with less choice about the moment.
That’s why we treat PDSL as the third option, not the first. The two routes below both cost less and do more.
PDSL vs the two better routes
| PDSL (typical retail) | Keep copper with us | Digital line with us | |
|---|---|---|---|
| Monthly cost | £25–£40+ | £13.99 | Wholesale pricing, calls up to 72% lower |
| How long it lasts | A bridge, on the network’s timetable | Until 2030 | Long term — it’s the destination |
| Your number | Kept | Kept | Kept |
| Your kit | Same phones | Same phones, same sockets | Modern handsets or apps |
| Who sets the timetable | The network | You | You |
Route one: keep your analogue line until 2030 — same line, number and kit at £13.99 a month. Route two: move to a digital phone line — future-proof, with call costs up to 72% lower. Either way, the line rental itself is guaranteed the UK’s cheapest — find lower and we beat it, plus a month free.
Ordering any of the three takes minutes
Tell us the number and what the line does today. We check what’s on it, confirm the honest best fit — PDSL included, if that’s genuinely what the situation needs — and handle the whole move with your current provider. Your number stays yours throughout, and nothing changes on your side until you say so. Since 2005, from our offices in Poole and Hyde, that’s been the whole model: wholesale prices, experts you can actually speak to, no ticket ping-pong.
PDSL FAQs
What does PDSL stand for?
PDSL stands for Pre-Digital Phone Line — an analogue-style stop-gap service that keeps basic calls working after the copper network switch off in January 2027, for lines that haven’t yet moved to digital.
Will my line be moved to a PDSL automatically?
If the January 2027 deadline arrives and no digital arrangement is in place, moving the line to a stop-gap service is the industry’s default way of keeping calls alive. The timetable and terms sit with the network and your provider — which is exactly why deciding deliberately beats waiting.
How much does a PDSL cost?
Expect retail-level line rental — typically £25–£40+ a month from major providers. That’s more than keeping your analogue line with us at £13.99 a month, and more than moving to a digital line, which also cuts call costs by up to 72%.
Can I keep my phone number on a PDSL?
Yes — your number stays with the line whichever of the three routes you take: PDSL, keeping your analogue line until 2030 with us, or moving to a digital line.
Is a PDSL better than keeping my analogue line until 2030?
For most businesses, no. Both keep an analogue-style line working past January 2027, but keeping your line with us costs £13.99 a month against typical retail PDSL pricing of £25–£40+, runs until 2030, and leaves the timing of any digital move with you rather than the network.
Do you actually supply PDSL?
Yes. Where a PDSL is genuinely the right fit — analogue-only equipment, premises in transition, no usable broadband yet — we supply and manage it. We’ll also tell you straight when one of the other two routes serves you better, because it usually does.
