Shouldn't be an issue, a boiler needs an electrical supply and the programmer is just an on/off switch.
Unless they have some obscure internal controls, which can be linked out, any programmer will work.
The only issue is if you buy a single or twin channel, as a combi only needs a programmer for heating, you only want a single channel, and a permanent supply for the hot water to work.
