Difficult to find radiator size

[Ahearsum]

Hello.
I need to replace a radiator 2250 x 450mm. I'm finding it hard to find a new one that size. I see Radson make one that size but I have found no UK stockists. Does anyone know where I should look? Screwfix has a 2200 x 500 which would do at a pinch but I'd rather get the exact size.
Thanks

If you want a uk manufacture/supplier. You will have to buy the 2200 and use 2 x rad tail extensions
