From Zooplus: Bozita canned food is popular and very economical. I
think it's about 4% calories from carbs. (Bozita also do a chunks in jelly type food, slightly higher carb, in tetrapacks). The link is here:

Bozita is also available from some independent pet stores and garden centres.
Also from Zooplus are Catz Finefoods and Grau 'grain-free'. Some of the Catz Finefoods are very low carb indeed. And Zooplus have mixed trial packs of it available at the moment, so it's a good chance to try out the different flavours.
The Grau 'grain-free' has about the same carb content as Butchers Classic, I think (about 8%), but it is a premium food with high meat content. It's pricey though, but can be quite economical in the huge 800g tins. There is a trial pack of Grau grain-free available at the moment too (but the yellow tin in the pack works out too high in carb for diabetics...)

Zooplus offer free delivery on orders of over £25. The parcel will need signing for. (Or I think there is the option of getting the parcel delivered to a post office to be collected from there).
The Happy Kitty Company also have some good foods that may be worth a try.
Some of the Mac's grain-free varieties are very low carb. It's a good quality economical food too. Ropocat is also available from the Happy Kitty Company, as is (going up in price range and quality) Granatapet. Granapet is popular with many cats, and most varieties are very low carb.
Delivery costs for orders over 5kg (equivalent of around 13 x 400g tins) is £3.95. But The Happy Kitty have some special trial offers going on too (including postage costs) which may be worth considering.

There are
lots of other good foods out there too. For specific varieties and carb values do have a look at Juliet's (AKA 'Dr Schrodinger' here at FDMB) 'Useful Food Chart For Brits'.
