Taps

[Amadeus]

Our kitchen taps need replacing. It's a monobloc tap at the minute, mounted on a granite work surface.
Are Monobloc taps a standard dimension in terms of the hole req'd in the worktop i.e. can I chose any monobloc taps or do I need to determine the dimension of the existing tap?

thanks

Pretty standard in the UK.
