Which was why I qualified the advice..

Either short trips, where you know you can get back home to a charger, or longer trips where you have very carefully planned where you can definitely get a recharge.

Making a cuttings deflector, for the back of the tractor. It discharges, blown via a duct, from the deck, then out the back into a large hopper - as designed. Except, due to the amount of moisture in UK grass, it frequently chokes in the duct, and needs the hopper removed to clear it. Without...

Two heads are always better than one :-)

I remember those, they balanced rather awkwardly, hanging from the lampholder.

Yep, almost certainly it will be a failure of the 2-port actuator. My system uses a 3-port, and I keep a spare, new actuator head to hand, ready to swap in just in case of a failure.

No, it only opens the valve. With timer and cylinder thermostat, both set for demanding heat, the valve actuator should run to open position. If not, chances are - that the valve actuator has failed. Often that failure will be the actuator motor. It's pointless just making assumptions, though...

Because there is no exposed metalwork, which might pose a risk, if it became live.

It could. The valve has to signal to the boiler, that it has opened, before the boiler will fire to heat the water. The sequence is time-clock > cylinder stat > valve > boiler.

Your florescent hopefully does/did have an earth connect, it is a requirement. A straightforward lamp holder and incandescent lamp, will not need an earth, so just ignore the earth terminal. Your diagram for the florescent, is just to explain the operation of such a fitting, it ignores the need...

You will need to ease that C shaped clamp off first, then open up the the crimped up flat strip under it. You will then need to source a jubilee clip, with which to replace it.

No, from my memory - let the gas guys confirm it first!

My understanding was that if any appliance is greater than 70Kw, then it becomes a commercial installation.

Nope!

Yes!
