It means unlimited sockets assuming the majority are only used for low power
appliances - which is true in most situations. The modern kitchen is an
exception. When the 13A socket system was designed in the 1940s, deep
fryers, dishwashers, kW+ combi microwaves, etc, weren't really taken into
account :-)

You might want to run a separate, non-RCD, circuit for the fridge while
you're at it. And put in provision for an electric cooker at the same time.
Even if you don't use it, a future owner of the house might appreciate it.
