The Project Debut Carbon with Ortofon 2M RED cartridge is a pretty decent system, but no PHONO built-in. These built-in Phono stages are rare in better turntables.

The next step up is the Project Carbon Esprit for £499 with the same cartridge -
Superfi - PROJECT DEBUT CARBON ESPRIT TURNTABLE
There is one decent turntable that has a built-in Pre-Amp as well as USB, that is the Audio Technica ATLP120USBC USB for £279 MINUS the cartridge, there are several cartridges available in the roughly £50 to £100 range.

I am reluctant to go any farther DOWN the scale than that.
Moving up the scale, the Project Xpression III with the same 2M RED cartridge is about £450 -

But NO Phono stage. Also with the Project Carbon/Esprit the Ortofon 2M Red is about the correct grade cartridge, but for the Xpression III, I would recommend the 2M BLUE. The 2M RED is about £85, the 2M BLUE is about £169. Though that's purely a matter of choice; the 2M RED is highly regarded in its price range.
Moving up Higher, the Project Xperience (no Cartridge) is about £679 with this very likely you want the 2M BLUE rasing the price to (£679 + £169 = ) £848.
I'm using Project as an example, many very much prefer the REGA turntables from the modest Rega RP1 -

But NO PHONO Pre-Amp in any of them.
I used Superfi links only for convenience, these are all common products available from a wide variety of sources at similar or perhaps better prices. A simple Google-UK shopping search will help you find locations near you and the best prices.
The only turntable that truly meets your requirements while meeting my minimum standard of quality is the Audio Technica. This is a quality turntable for the money, it does come with a VERY basic Audio Technica AT95E cartridge. Though I suspect, you will eventually need a cartridge upgrade. The AT95E cartridge is worth only about £40.
