London Indoor Softball League is back for 2023! This uniquely British take on indoor softball is one of the best ways to stay active during the spring season, with modified, fast-paced rules and more hits than the Beatles – but don’t take our word for it - watch the video from the Pork & Pitchers team to get a feel for the game below!

Here are all the details:


The league is divided into two divisions, with Competitive (Comp) and Recreational (Rec) divisions playing on alternate weeks. All teams will have five weeks of regular season play, with as many games possible per day.

Those registering teams are welcome to request a division, but, in the interests of fairness and to balance both the Comp and Rec divisions, BSUK reserves the right to make final decisions on which division teams will be assigned to.

Please note that all venue rules must be followed, and no alcohol is allowed on site. Failure to follow these rules could jeopardise the league.


London Indoor rules are bespoke to the format, and you can find them below

League fees will be £150 per week.  You will be asked to pay the first week's £150 at the time of registration using a credit or debit card, but may choose to pay later. All payment will be completed using EZ Leagues, and you will receive an invoice upon registration. 

Please note that your team is no officially registered until the first payment is received in full.

There will not be a scratch team this year; however, individual players who wish to get involved can email Liz Knight here.


To register a team, click one of the buttons below. BSUK reserves the right to ask teams to change divisions to ensure fair competition.



Please note that by registering, you commit to playing all on all the weeks assigned to your division.

Should your team not be able to play on a given week, you will still be charged as we have venue hire costs to meet.

The deadline for registrations is 18 January at 5 PM.
