Business Line Rental Explained (and Why It's Disappearing)

"Line rental" has been a fixed feature of business phone bills for as long as anyone can remember. But it's a charge that's about to vanish - and understanding what it actually is explains why. Here's line rental in plain English, including the wholesale product (WLR) behind it.

What line rental actually is

When you pay "line rental", you're paying to keep a physical telephone line connected and working - regardless of whether you make a single call. It covers the upkeep of the copper pair from your premises to the exchange and your continued access to the network.

Crucially, line rental is separate from call charges. You can have a line you barely use and still pay full rental every month. That split is why auditing unused lines is one of the easiest ways to cut a phone bill - more on that in our business phone line cost guide.

What is WLR (Wholesale Line Rental)?

Most providers don't own the copper running to your building - Openreach does. Wholesale Line Rental (WLR) is the Openreach product that lets other telecoms companies rent those analogue lines wholesale and sell them on to you.

So when you pay your provider line rental, they're typically paying Openreach for WLR underneath. This matters because Openreach is now withdrawing WLR as part of retiring the copper network. When the wholesale product goes, the retail line rental built on it goes too.

Why line rental is disappearing

The whole concept of line rental is tied to the old analogue network - the PSTN. As that network is switched off (by 31 January 2027), the lines you rent stop existing in their current form.

In their place:

• Broadband-only connections like SoGEA deliver internet without a traditional phone line - so there's no analogue line to rent.
• Voice moves to the internet via Digital Voice or hosted telephony, where you pay per user rather than per copper line.

The result: the "line rental" line item on your bill is replaced by a connectivity cost plus a voice service - often for less overall.

The sting in the tail: 2026 price rises

Before WLR disappears entirely, it's getting more expensive. Openreach is raising WLR wholesale prices through 2026 - by 20% in April and to around 40% above current levels by July and October - to nudge the remaining businesses to migrate. Providers pass these on, so legacy line rental is rising quarter by quarter. We break this down in the 2026 line rental price rises.

What this means for your business

• If you still pay line rental on analogue lines, your costs are rising and the product is being withdrawn - so plan your move.
• Keep your number - you don't lose it when the line goes. See keeping your landline number.
• Re-plan around connectivity - your new "line" is really an internet connection plus a voice service. Our analogue line replacement guide walks through the options.

The bottom line

Line rental is the standing charge for a physical copper line, propped up by Openreach's WLR product - and both are on the way out. Rather than pay rising rental on a closing network, most businesses are better moving to internet-based voice now. Want help mapping the change?
