Any ideas what this is please, just above (downstream of) the stop cock on the incoming cold water mains? I was thinking an old stop tap with lever removed(?), or maybe an old style pressure reducing/regulating valve(?) There is some padding between the body of it to cushion it against the incoming hot water pipe.

Many thanks

A bleed valve to drain the system down I think. Should be a nozzle on it that you can stick a hose pipe on. Well, I have one on my heating system. Something like this.

Thanks chaps, it didn't cross my mind there would be a drain point on the mains water. I've only ever seen them on central heating systems.

Maybe because your stopcock is soldered into the system instead of having a compression joint to release any water in the system?

Cheers. I'm looking to install a Pressure Reducing Valve, so may have to do away with the drain point. I wouldn't fancy using it as it looks very old. I also wouldn't mind replacing the stop cock as I avoid using this too due to age and potential leaks. I just shut the water off at the water meter outside my front door.

If you have a means of turning your water off in the street, it will be fairly easy to replace the stop cock (or maybe just the middle part of it) in the house. Always better to be able to isolate the supply easily in case of an emergency.

Water regs require a drain off there, although it would be much better if it was accessible

As suggested, shut it all off and replace it with a high quality full bore lever valve, at the same time you can re position everything so it is all accessible.
