It's not a bathroom, based on your description.
The Wiring Regulations (BS7671, currently 18th Edition) define Special Zones ( Zones 0, 1, and 2) in and around Baths and Showers, but that does not seem to apply here.
There is no zone around a basin, basin taps or toilets.
While BS 7671 doesn’t have regulations for kitchens or utility rooms, the 'On Site Guide' does include *advice* in section 5.2.2 'Location of accessories in kitchens' and there are recommended restrictions on the siting of electrical accessories in a kitchen such as near sinks, ovens or hobs. Basically, the advice is that sockets should not be closer than 300mm to a sink, but in your situation, they are on the opposite wall so that doesn't apply.
Basically, you're good to go.
