GO Mammoth Avis 

I attend the Chelsea 5-aside league, and it is great fun. The matches start on time, the players and teams are all respectful, and the matches are fun. We play at the Chelsea Academy pitch, and it's a lovely, well-kept pitch.

Being with go mammoth volley for several years. It's fun made it simple for everyone

It’s so much fun! It’s well organised and everyone I met was kind and fun to play with. Hopefully I’ll just keep playing!

Joining GO Mammoth has been great for both my physical and mental health. Playing sports with a team again is so much fun and GO Mammoth takes away the stress of organising it

A great league, with really nice teams, knowledgeable and kind umpires and really well run. Able to access everything needed via the website. Happy to be a part of GoMammoth!

Fantastic website and organisation, matches are organised for you, equipment provided, pitches booked and all information is well communicated. You can simply enjoy the sport you love and socialise with people! Only positive opinion from me, many thanks to everyone who makes Go Mammoth possible! 😃

I paid 100£ to book 10 sessions of basketball at a venue of interest at mid of August 2025. The sessions would begin in the second half of September.

2 days before the start date of the booked session, I was emailed that there were not enough people booking this venue so they won't proceed with it, but that they automatically found a different venue for me and that if I didn't want to do that I could let them know and they'd offer me a refund.

It would take me aboout 5-6x more time to get to the new venue, it was way too far so I asked for a refund.
I got not reply.

It's been a week now and I've emailed them about 4 times for support and also tried reaching their phone number, to no avail.

At the same time, the team I was assigned to has one lacking player.

I don't think they will ever reply to me, repair the team's lost member or even repay me.

Worst experience I've ever witnessed.

I like that there are multiple sites for the sport I play (netball) across London and have been for about 3 years now. I like that they send availability emails each week as well as having a dashboard where you can see upcoming matches, league position etc

However, they are terrible at providing updates to league situations such as match time and/or match location changes for leagues. We've also played at 2 schools now and both times when the floodlights break on one side they aren't fixed for months. Also if any team settings need to be amended such as re-adding old players after the league has started, adding new players externally to the GM waiting list, or getting refunds for certain situations, the head office seems very disjointed and unorganised and it is such a slog to try and solve anything.

We love GoMammoth netball leagues! We've been playing for 2 years now and it's always been really fun and social. Our umpire is the best, would recommend!

Having so much fun playing with Gomammoth netball league. The sign-up process was easy. There is a positive, sociable atmosphere at games. The refs have been very friendly and welcoming, having a laugh with us while being fair.

The office team respond quickly to my calls/emails and have been really accommodating - helping to find additional players as we didn't have enough for a full team. Would definitely recommend Gomammoth to anyone wanting to start/get back into netball :)

Great easy experience and enjoying the league

The league is great fun and the gomammoth staff, from the umpires to the table are making everything runs swiftly. I can't recommend them enough

I've had an overall great experience with the go mammoth netball leagues. They are well co-ordinated with great umpires and like-minded, netballers. There are sometimes a few issues with logistics, but a minor issue. Overall would recommend. School 21 netball on Saturdays.

Well organised, great umpires, I really do have fun playing even though my team never wins, the other teams are very gracious. My only con is the lighting on the court, it needs replacing especially going in to autumn.

The netball league with GoMammoth is great. Their website info could be better - I'd have signed up earlier if I'd realised I wouldn't individually have to find a sub for any time I was on holiday. But I'm really pleased I joined and it's a great way to get a bit of fun exercise with nice, like-minded people. And if you phone up, the people who organise it are helpful.

Well run, any issue has been resolved swiftly, great way to make new friends.

The league is great. We've really enjoyed playing. The pitch is great, refs are great and love the quick score updates online

We compete in multiple leagues as a team, doing multi-sport in the winter and then rounders in the summer for the last few years. I love it! I love the opportunity to experience different things and there is such a great balance between competitive and friendly fun. Would recommend.
