Many users get their Broadband & don't give a thought to the landline, despite without it they wouldn't have BB. Then the BB starts playing up often due to the phone never being used on the landline.
After long periods without any electric current passing down the line, joints can become oxidised & corroded. This could impair the Broadband sharing the same line.
So, it's worth buying a cheap corded handset, which can often be had for about £5, & making the occasional call to "wet" the line. Also having a handset is invaluable for helping diagnose Broadband faults. This could well save you the cost (£50 from EE or upto £85 for other ISPs) of an engineer call-out finding the fault lay within your home.

Not made a landline call in years in fact don’t even think it’s plugged in anymore so this confused me - if it’s running thru same earthier/cable surely being on the phone your blocking that signal line? (Broadband?)

No, @R-ainbow24 , BB & voice use completely different ranges of frequencies. There's no overlap.

For some reason this came up in my timeline as @XRaySpeX must have made an edit so maybe I can update it slightly.
Ringing a phone occasionally does not "Wet" a line as such. It can help on breaking down oxidisation on joints as it puts through a higher than "wetting current".
Having a handset plugged in will supply a closed low voltage wetting current without even using it. Although this wouldn't make much difference to ADSL lines due to the frequencies involved it has a beneficial effect to VDSL lines.
Not only that but for diagnostics a handset is the cheapest (£5-£10) most simple diagnostic tool available.
By far the bigget cause of VDSL signal drop out is noise on the line, it is a killer for VDSL. Add to that your broadband will work, albeit at a slower rate if only one of the pairs of wires is connected. A handset will quickly tell you where the issue is and allow you to either report a phone line problem (quicker resolution) or a broadband one. Openreach have more line engineers than broadband ones presently and they are different fault queues, both have the same SLA's (Service Level Agreements) but different engineer availability. This means line problems are normally rectifide quicker.
A line engineer cannot request a DLM reset unlike a broadband one but once the line issue is resolved DLM will normally reprofile the line within a few days automatically.
So how to use your hand set to diagnose the problem.
First, do youhave a dial tone? If no report a no dial tone fault.
Second dial 17070 option 2 is there noise on the line? If yes then you need to rule out any internal wiring fault by connecting the phone to the test socket with a filter and checking again. Be aware this is only with split master sockets and the newer ones have an interstatial plate which also must be removed (see photo).

Couldn't edit my post but I've found the reference for wetting current.
"A related term sealing current (aka wetting current or fritt current) is widely used in the telecommunication industry describing a small constant DC current (typically 1-20 mA) in copper wire loops in order to avoid contact oxidation of contacts and splices. It is defined in ITU-T G.992.3 for "all digital mode ADSL" as a current flowing from the ATU-C (ADSL Linecard) via the phone lines to the ATU-R (CPE)."
Having a phone plugged in assists this.
