Looking at ones available online they have a 3120 watt rating which works out at 13 amps and that is the fuse rating.
You can buy them for about £10 so messing about putting new cable on may be false economy.

Have you considered a master/slave extension socket? You plug the television into the master and peripherals into the slave sockets. TV on, all the rest fire up. TV off, they all go to sleep. Fairy magic.

Is that off at the TV or off at the socket?

Plug the extension lead into the wall socket. Plug the TV into the 'master' socket, and all the peripherals, e.g. Sky, DVD player, etc. into the 'slave' sockets. When you turn the TV off with the control zapper thingy all the other bits 'n' bobs follow suit, and vice versa. I use a setup similar to this one to power my saw and associated dust extractor. Speak nicely to a certified sparky and they'll soon put a longer supply lead on for you.

That isn;t very helpful if you have a tuner/recorder that you use in the quiet hours.

In which case you use the sockets that are permanently on, not the turny onny/offy ones.

Most cable in the UK is sold on the wire size.
13 amp fused plugs normally attach to 3x 1.5mm cable.
As the old man Ex Bay has suggested 3x 2.5mm will do the job quite comfortably.

Don't get muddled up between 'cable' and 'flex'. Cable is the stuff that connects up your ring main whereas flex is the bit that runs from the socket to the appliance. Too small, and it'll get hot/very hot. Too big, and you won't get it through grommets and fixings on the extension lead and 13 amp plug, etc. If you're not 100% sure, you must let a qualified leckie do it. Pedants hat off.
Flex is available in a range of sizes. Check the table to see the size you need for different appliance ratings.
Appliance rating Flex size
700W 0.5mm2
1.4kW 0.75mm2
2.3kW 1.0mm2
3kW 1.25/1.5mm2

That's what I was trying to get at. I've noticed that flex comes in different types

Yes, for indoor applications you'll just need the regular plastic sheathed stuff. Incidentally you can get it in different colours to suit your decor. At 'Fuse Mansions I've used some 'antique gold' which blends in nicely with the colour of the carpet.

Look for the technical data label on each appliance. It'll give you voltage, frequency, and wattage. Ball park figures, TV 150W, Sky box 45W, Soundbar+woofer 80W+160W, etc. Add up the wattages. I don't think you'll get anywhere near the top end of 3000W (3kW) for 1.5mm2 flex.
If you do go for my suggestion of the Master/Slave extension, you'll need to plug the Sky box into one of 'on all the time' sockets as Sky sends out software updates usually at 2 am.
