Or
I could install a 2-way light switch between the feed to the old timer and
cbus, and the feed to the boiler. So when switched one way, CBUS controls
feed. When the boiler man arrives, flick the switch and the old timer
module now controls the feed.
Sounds plausable...

That works!
What I have done is put a relay from the Timer output to the boiler
Then I run the timer to always be on
The relay the says when it is off via in my case HomeVision
The advantage of this is I then have a test mode where the relay is
always on
So if any one comes to fix the boiler
Put it into test mode and as far as they are concerned it is a normal
control system they are used to
I have a 12v 2 mains relay in the boiler
That way nothing control wise leaves the enclosure
Far better that running mains from the boiler to the C-bus relay and
back again
If that isn't clear give me a bell or mail
