Then start with that - apply it to the short link wire, at the double switch, report back whether that is live, or not.

Is this the wire you mean? Test at either end?
That's the wire - it doesn't have to be at the end for non-contact tester.

No, anywhere along the wire - if it's what we think it is, it should be live when tested anywhere along it's length, as should be the wire it connects with..
However, the problem with using a "non contact voltage tester pen" is that one cannot test for Neutral continuity with such a device.
Any circuit needs to have a "return path" to the "source" - which is provided via the Neutral.
Such a "return path" can be tested only by using a low impedance multimeter -
or
a "Test Lamp"
OK so used the pen and the link wire isn't live any other suggestions please?

If none of the wires at the switch are live ,then examine the wiring at the light fittings. The feed to the switch is very likely coming from there. May just be a loose connection there.
Actually, you can....
If the switch is turned on, with a load, with a neutral present at the load, the neutral will no light up the tester. If it lights up, it shows a lack of a neutral.
I think that will be very confusing for a DIYer without saying there is only a switched-live present at the switch; not a neutral.
It needn't be, with a bit of common sense applied.
Make use of the tester, on the wiring at the ceiling rose.
Hopefully, before you began using the tester, you confirmed the tester was working? Always best to test it, before use, then again after use, just to be sure.
Yes I've tested it before use on other switches in the house and the tester works, I've now just tested the celling lights and they are also not live either
The suggestion was, to test the wiring at the ceiling rose itself. Unscrew the ceiling rose cover, and try the tester on each individual wire. Check at each ceiling rose, where the light is switched by those two switches..

Right. Both lights are not working.
So, these wires at the switch positions may have been disturbed by the tenant.
I would check if the wires in the COM terminals are live.
There could be a continuity issue on the live, either where it enters the switch terminal, or at the ceiling position. There could also be a broken neutral at the ceiling position.
Are any of the light fittings different to the ones in place when that tenant first moved in?
