No — a prenup does not need to be notarised in the UK. What matters is that it is properly executed as a deed, signed by each partner in front of an independent witness.
Where the notary idea comes from
In some other countries, prenups must be signed before a notary to be valid. England & Wales does not work that way — so there is no need to find a notary public. The confusion usually comes from couples comparing systems abroad.
What is actually required
A prenup should be in writing, executed as a deed, and signed by each partner in the presence of an independent adult witness who also signs. Alongside that, the things that give it weight are full disclosure, independent legal advice and fair terms (see are prenups legally binding? and what to include).
