ClubSpark Club Management Software tools are provided to the LTA registered venues. All players and members of those venues are required to access the ClubSpark club tools, i.e. for court booking or course registration.
Having an LTA account does have benefits and there are a range of different levels of accounts, some are free and some have costs. Please see this link: https://www.lta.org.uk/advantage/compare/
There is also a quick quiz to go through and work out which plan best suits you: https://www.lta.org.uk/advantage-home/
If your venue uses ClubSpark for collecting club Membership then you will automatically be eligible for the ADVANTAGE PLAY + , you can also register and opt in if you meet this criteria.
I would recommend taking the time to visit the LTA website for more information on the benefits on this and choose the best account that meets your needs as a player or fan.
