I am to install central heating in my house and need a single socket
for the boiler to be close to it.

Can anyone advise which is the better option -

1) To take a spur from an existing socket on a ring to this additional
socket or

2) To take a spur from a junction box intercepting the ring main. I
understand from this that I need to remove the sheathing on the cable
and strip away some casing to leave about 1/2" of the neutral and live
exposed and connect this without cutting the 2 wires. The only wire
that needs to be cut in 2 is the earth wire and then linked to the
spur.

I think the junction box would be the easier option as I could take a
feed from the cable in the ceiling as the socket is needed half way up
a wall. The socket spur would involve a wire going down from an
existing socket into the cellar, along then up the wall.

Any advice would be greatly appreciated and many thanks in advance.

You can do it either way.
My preference is to to take the spur from an existing ring socket.
Then the junction can be always examined in case of problems.
If you do use a junc box it must be kept accessible.

One advantage of a socket is that you have the capability to run the
CH system during a power blackout if you are in a rural area.

Aldi sell small petrol generators occasionally for about £75.
Can also get invertor units which run off a 12v battery.

There's no requirement to avoid cutting any of the 3 wires.
(Having said that, I do try to avoid cutting conductors that
are to be connected anyway, but it's not worth jumping through
hoops to do it.)

Do whichever is easiest.
Incidently, if you fit a socket for the boiler, it should be
an unswitched socket. Alternatively, install a switched fused
connection unit (which will be double pole switching).

Presumably then a DP switched socket would be just as good?

Hwyl!

In theory yes. In practice no, as the CORGI installer
probably won't understand why the rule is there, nor
be able to tell if the socket is DP switched.

The normal way is to use an FCU to feed the CH electrics. And it's
probably better to run the feed to this direct off the CU on the none RCD
side.
