new thermostat

Care to elaborate with a make and model? Might just be better either going for a battery operated one or wireless one.

Yep so depending on the age of it could be using 24v. Opening up that particular boiler does require safety checking afterwards.

if you have an internal or external existing timer, this will have to be set to constant on, in order to test the wires at the thermostat

i understand i could run a power plug designed for something like this to give it power https://www.amazon.co.uk/gp/product/B09TPJS5MS/ref=ox_sc_saved_title_3?smid=A151HA45N9AR70&psc=1

Good morning right I have looked at my isolated switch near boiler an the grey wire is connected up so looks like it possible to wire smart one up

That may depend on the connections available at the other end of the cable.
For a simple solution, you could consider something like a battery operated Nest Thermostat E?

This is what at other end

That shows us the wiring to a triple pole isolator, and doesn't really tell us more.
We still don't know if the wiring entering the isolator is connected to neutral (which would be naughty if it was, considering the free floating grey wire beneath the current thermostat).
And we still don't know if the thermostat was switching live or 24V - both would still work through the isolator.

....although having an isolator between thermostat and boiler would seem odd.

Does the other wire go straight into the boiler?

3 wires go to the boiler I have looked in the programmer an the grey neutral is connected aswell don't no if that helps
