The Highway Code is useless - read the Traffic Signs Regulations and General Directions 2016.

There are two types of traffic signal, primary and secondary. The primary ones are associated with a stop line, and the secondary ones, often on the opposite side of the junction, are not. If you're past the stop line and the primary signals, you should not attempt to comply with secondary signals.

That's interesting. Though on the secondary signal I mentioned previously that doubles as a pedestrian crossing, if I see someone waiting to cross I'm always prepared to stop on red. As I presumed the pedestrian would have priority once they stepped onto the carriageway?

If a pedestrian is in the road, then of course you should stop, whether there is a red light or no light signal at all!
If there is a red light, but no stop line, then, as said, it is a secondary signal that supports the primary signal and is there for improved advance visibility but only applies to a relevant stop line.

On the side of the road where it is the primary light, there is a line. On the other side of the road where it is the secondary light, there is no line. There are crossing buttons on both sides of the road, and a small island in the middle of the road with a crossing button.
