Can anyone identify this tap?

[Schmeebee]

My tap is dripping and it's becoming a lot worse - I think I need to replace the ceramic disc valves but i'm having trouble identifying the tap in order to find the right replacements. Anyone know what model/make this is?

Any tips on where I could look would be great

It looks like the one I have. If so, it’s a Blanco BM/4550. I bought it from Homebase or B&Q (can’t exactly remember), but I do have the Installation sheet and it has a number for after sales and spares....01923 635300

Have you tried removing a cartridge and taking it to a plumbers merchant?
Most tap cartridges are one of the standard sizes and replacement pairs can be bought locally for less than a tenner. Replacements from the manufacturers are likely to be £30-£70.
Always worth replacing both sides because the other cartridge is just as old as the failed one.
If you do this, take the tap handle too to make sure the new cartridges will fit the handle.
