Probably the thermostat stuck part open - that's the more usual way for them to fail, so warmup take ages, if at all...

My thermostat has a gap when in the cool, closed position, a couple of millimetres, is that a gonna then?

a thermostat will tend to fail partially or fully open

Thanks Allan
So I should change the sensor.
It’s located towards the front of the engine near the injectors? Should I remove the alternator to reach it?
What would be the best way to go about this?

When ordering John Cradock has two:
STC3338G At £17ish
STC3338 at £6ish
Both fit apparently but is it worth £11 extra for the G?

The way i look at things like these.. it's not bank breaking.. but having to replace in 6 months is a pain. Do you trust your engine to a ~£5 part?

I have removed the radiator, fan, fan cowling, and got the thermostat out.
It seems to work okay yet doesn’t close completely and the integral rubber seal suggests it should.
Should I order a new one?

Yes and make sure you test the new one in boiling water before fitting, there are a lot of duff ones about.
