Description:

Noticed this small dark spider sitting on the plughole filter of our shower. Its body and head are about 6-7mm. Could it be a False Widow Spider? A few days ago we returned from Tenerife - could it have crept into our luggage and got out? If it is this species, should I kill it as an invasive species, or let it go as there appear to be many in the UK now?

Steatoda nobilis

This spider has probably been enjoying the house while you were away and just couldn't get out of the shower. S.nobilis does have a significant bite but if you do not provoke it it should not harm you. If you wish to let it go, it would like a shed or outbuilding of some sort.

Steatoda nobilis is well established around London, so I wouldn't worry about it !

As Dennis says - they aren't much to worry about, being docile and only tend to bite if accidentally trapped against the skin.
