Gravity circulation not unusual with older systems. A gravity check valve can be fitted in the flow this is like a clack valve and will open when the pump is running. otherwise turn the u/s rads off but then look for leaks on the rad valves

The radiators near to the boiler will get a little warm because the water in the tank expands when it is heated ---on the older boilers that is

The valve which stops the heating water flow must be allowing some hot water to flow around the system, albeit slight.
Heat rises so the heated water will remain at the top of the system if the pump is not operating.
Sometimes there is no valve and the system relies on the heated water rising into the cylinder to heat the water, and then switching on the pump to circulate the heated water into the central system. This may be the cause.

If like mine it is an older boiler it will be because it is a 'gravity feed' boiler the only way to stop upstairs radiators being warm is turn them off.

I should not worry, the pipes from the boiler that goes to the tank are all next to each other, so partial warming of the other pipes has to happen, as the heat rises it travels upwards.

You don't say how many zones you have but, apparently the zone or, the valve that shuts off the heat to the upstairs is not, shutting the valve. Therefore, if it's that much of a problem really, then you'll have to get someone or a plumber to take care of the situation.

cos the water in the boiler warms up the water in the radiators?

the heat will rise to the upstairs radiators regardless of the pump being turned on or not

residual heat rises in the pipes to the highest level.
