A hall with top and bottom lights and top and bottom single switches.

When top switch is on, only top light is on.

When bottom switch is on, both lights are on. Top light cannot be
switched off with top switch.

Any suggestions?

I am reluctant to investigate further as it is a rental property.

Sounds like the person buying the switches had not heard of two way switches
when they put them in.

A wire is taken from the switched live at the hall switch to both
the hall and landing lights. So when you turn on hall switch it
provides power to both light fittings. This cannot be turned off
using landing switch.

The landing light also has a switched live from the landing switch
to the landing light and can therefore independently turn on and
off the landing light (provided there's no power from hall
switch).

In which case report the fault to the landlord or managing agent and let
them fix it...

I thought it was still "recommended" and not in force for existing
tenancies until July 2021??

That is my thought. There is a general philosophy that an electrical
fault needs looking at sooner rather than later.

After much sketching, I think I have it figured.

Top switch is two way.

Switched live to bottom light also goes to NC of top switch. NO of top
switch is an always live wire. COM goes to top light.

That would explain why the top lamp has a brief flicker off when
switching the top switch with the bottom light on.

Any other theories?

Yup, that then gives the landing light a choice of "on" or "same state
as the hall light".

That would explain why the top lamp has a brief flicker off when
switching the top switch with the bottom light on.

The switches are break before make, there would be a very brief
interruption in power.

Any other theories?

That sounds seminally plausible and simple, so Occam's razor suggests is
a good one to go with!

Do you know which circuit the upstairs permanent live to the switch fed
from? Since that will dictate what you can do easily from the current
starting point.

It has to cover both.

Or you get the phone call that the lights do not work.

I agree. Maybe only the top light existed originally, and both
switches are two-way so that either one can control the light. The
hall light was added later, connected to one of the two wires joining
the two-way switches.
