Looking for an all in one solution in the UK

I am currently having to use 3 different vendors for lights/switches.

I have a TP-Link plug but their bulbs are > £30 a piece.
I have LE bulbs at £11 each but they don't do any kind of plugs.
I have a a Sonoff USB A switch. They do a plug but no bulbs via Amazon and only screw fitting ones in store.

I am wondering if there is a company that does all 3 at a reasonable price.

Cheers,
Bode.
