You can't hard wire into an existing socket. The sockets in the Kitchen are wired in 2.5mm twin and earth cable and protected by a 32amp circuit breaker in the Electric box. The ALDI extension uses a 1.25mm. cable and should be protected by a 13amp fuse.. You cant change cable sizes without another fuse to protect the smaller cable. Just use the RCD plug in so no one gets hurt.

If you have cable exposed on the outside wall then you leave a small "U" bend in the cable so the drips fall off before entering the wall. Drill straight into the wall using a mortar joint between bricks. Use a smaller than required masonry drill bit and open up the hole from both sides to the required size. Avoids excess damage to the interior plaster.

Or do what the pro's do and buy a tube of invisible/clear waterproof silicone seal. The remainder of the tube will have a hundred uses around the home.

Just remember that when you drill external holes that you angle the drill bit so as you drill at a slight angle UP into the house, this along with gravity will prevent water entering your house.

My bad, I thought you were referring to hard wiring the supplied RCD.

As comment above, taking a spur off the ring main, or radial, is not an option.

Wouldn't a in-line outside plug be better? You could hard wire it into the kitchen ring main? Via an existing kitchen socket.

Like I said, you'll need a sparky if wiring DIRECTLY, i.e. without the RCD plug, like MannyFresh suggests.

So basically spur of an existing kitchen socket

Got one of these last year, excellent and simple. Drilled hole through garage, plugged into the socket in there and screwed on the wall outside the garage.

You'll likely need a sparky to sign it off if hard wiring it in directly.

Comes with a hard wired RCD, reason it isn't already fitted, apart from the money saving aspect from the retailer, is so the cable can be fed through window frames etc, then wired.

Just so folks are clear, it's either the extension box or the walk socket for the price, not both!

They tend to be plug in but I would check before purchase, it may be inline but I doubt it.
Looks very similar to homebase BG socket and RCD.

Didn't realise it had a plug in RCD with it

1.25mm cable?

When wiring this socket I suggest putting a plug on the end of it and plugging it in, don't hard wire it in to a circuit.

Looks like a good deal, heat
