Sunday Swim

Sunday Swim discontinued indefinitely

Updated at 19:30 on 17th March 2020:
Energybase have now closed completely until further notice in response to the current situation with COVID 19 and in line with the latest government advice.

The Naturist London Sunday Swim is therefore also suspended until Energybase are in a position to reopen the pool and other facilities.

This situation is likely to persist for some considerable time but any new information that we receive will be posted here as soon as we get it.

Updated on 23rd August 2020:
The situation remains unchanged and we have no information about when it may be possible for us to resume. This is just to reassure people that the site is still being maintained, and that new information will be posted as soon as we have some.

Updated on 6th October 2020:
Energybase have announced today on Twitter that they do not now expect to be opening at all during October 2020. This is in response to the rising numbers of Covid cases. We will of course continue to post any further information as and when we receive it.

Updated on 15th February 2021:
Sadly the situation remains unchanged. This update is simply to reassure you that we continue to monitor the situation and that any news will be posted as soon as there is some. Stay safe meanwhile.

Updated on 18th March 2021:
Energybase have just announced that they will be closing permanently on 30th April 2021. Our understanding is that a new leaseholder is taking over the entire (former ULU) building. The future for the pool is not entirely clear but it looks like we may have to seek a new home for our swim.
As ever, we will post further information as and when we have some.

New Updated on 18th October 2021:
Energybase closed permanently on 30th April 2021. The entire building has transferred to Birbeck University with the loss of all the former sports facilities including the iconic 33m pool. A campaign by students and others to persuade them to reconsider has not prompted any positive changes. It is uncertain whether we well be able to find another venue in central London willing to allow naked swimming to be offered to all comers as we used to do at the former ULU.
As ever, we will post further information as and when we have some.

  • Ever been skinny dipping and wished you could do so more often?
  • Did you visit a nude beach on holiday and wish there was somewhere to go during the rest of the year?
  • Never tried but fancy giving it a go?

The regular Sunday Swim is Naturist London's core event. It is just like going to any other public swimming pool except that costumes are banished. Unlike many traditional naturist events, there is no booking, no membership and no commitment. You are welcome to just turn up whether or not you consider yourself a committed naturist.

Come and enjoy a refreshing dip before Sunday lunch. Come once or come often. Come with friends or come alone and make some new ones.

Walk in through the main Student Central entrance on Malet St, walk straight ahead and down the stairs to the "Energybase" health club. Sign in at the reception desk - be prepared to show some photo-id. If you want to use a locker, you exchange your photo-ID at the desk for a key-card; there is no charge and you get your ID back when you return the locker pass on the way out. Then go downstairs to the changing rooms. Undress first and go directly to the poolside. Pay the duty hosts before entering the water - exact money if possible please.

Please note, many other activities go on at Energybase concurrently with our swim. The changing areas are also used by those attending these and are gender-segregated. Only the pool area is naturist.

Children & Under 18s

Under 18s are welcome provided they are accompanied by their parent or guardian, who must supervise them at all times.

Parents of younger children should be aware that this is a traditional laned pool with a depth sloping from approximately 1.0m to 3.4m. Polystyrene floats are available and can be requested from the lifeguard.


The building was constructed during the 1950s and presented many challenges to adapt to meet modern standards. The pool is in the basement, down 2 flights of stairs. There are two retro-fitted lifts which allow access by wheelchairs users, however these must be operated by a trained member of staff. In addition, the water surface is not flush with the pool edges but a hoist is available to allow the lifeguards to assist if required. If you would like to join us but require assistance or have any concerns about access, please contact the Energybase reception on 020 7664 2002 / 2091.
