What if a pilot light blows out? Is the householder allowed to relight it? Since this involves removing the cover, but if you know how, its no more involved than turning on a gas fire . . .
there is the small matter of a connected filling loop contravening the water regs, but it doesnt contravene the gas regs,

There are quite a few combi's nowadays where the filling loop is integral to the boiler. How does this then contravene the water regs when they are built this way by the manufacturer? After all these ones are permanently connected.
Just had a quick look at the combi in my house and the filling loop is integral. Gloworm 30CXi. Must be as you say and have a one way valve fitted somewhere.
Just watched Cowboy Builders
If the loop was on conical trampoline capillary system.....This would not only be dangerous, but would seriously compromise the efficiency, and safety, of the entire Flux Capacitor......
