Lovely social netball league with really friendly teams and a good standard of netball played across teams. I really enjoy being part of this league. 4 stars due to the umpiring which can sometimes be hit and miss although I think that is usually when they are training more umpires to make sure we have enough for all matches.

I am very satisfied. I returned to basketball after a long period. It is the best relaxation after all the work and stress and a complete discharge of energy. Good refereeing and environment.
I am 45 years old. If you are wondering about age, it is never too late to start again.
I recommend it to everyone.

Well organised and run 5-a-side football competition. Nice to get out after qork for a bit of competitive football. Would recommend highly!

I've been playing 5-a-side with GM for 5 years now. The pitch we use (Angel) has no facilities - no changing rooms, no water, no toilet, no 1st Aid, and the balls are often flat and falling apart, and the nets in a state of disrepair. Despite this, they continue to squeeze what profit they can from us, raising the cost frequently (it's already the most expensive of leagues) and reducing the time allowed for half-time, and in between games. There have been many instances of them telling us the game has been cancelled due to double bookings, of the pitch (Somers town), or some other reason, 5 minutes before the game was meant to start, after we'd all travelled there. Despite me asking again and again to take me off their email list, they continue to send me emails to invite me to new leagues, even though I've made it clear (about 6 times) that I'm already in 2, and aren't looking for more. We'd have sacked them off a long time ago, but sadly they seem to have the monopoly for mixed leagues. If another provider comes along, we'd switch in an instant, and most of the teams in our league feel the same.

Paid over £100 to join a football casual league ran by go mammoth. Arrived for first game and it kicked off 20 mins late as the first game had still not finished. We were provided with bibs which smelled absolutely terrible and like they had not been washed for weeks. At the beginning of the second half the ball was kicked over the fence into the garden. Turns out the referee had only brought 1 good football with them. We then stood about in the rain for another 15 minutes while they tried to find another ball as the ref brought no spare or a ball pump. We ended up using an old waterlogged flat football for the second half that belonged to the school. The ball was so bad that the referee asked if we wanted to abandon the second half but we had already travelled there so we continued. We ended up finishing nearly 40 minutes after were supposed to. Absolutely shocking product for the price. I asked for the price of the first game to be refunded and they argued that we still played a full game. A game played with a flat water logged football in unhygienic kit that finished nearly 40 mins late. Some service...

Very little customer service, they will constantly email you to try to grab your money for other leagues, but for the league you have paid for, you are on your own with no updates provided or very last minute communications about whether your games are going ahead or not. Paid £90 for a league of 8 full matches in September, have received one 15 minute friendly and no replies to emails to return my money. For signing up as a single participant, we have been put into teams with insufficient players so obviously nearly every game needs to be forfeit. Wouldn't recommend at all. Wish there was another option.

Unfortunate that they have a monopoly on this type of structure.

Been playing for 4 seasons now, and the issues just keep growing. As mentioned in other reviews, the refereeing is very bad and usually accounts for lost games (this is consistent throughout London as I have been told many times). Since I've started, multiple people in the league have been injured multiple times due to illegal screens, people grabbing you from the neck and shoulders during a layup, elbows flaring head and ribcage height, and the moment you mention it to the referee they ignore you. Same aggressive players will continue to play as such for the rest of the season, injuring more people with no repercussions.

Many teams will also make the play-offs, and will then reach out to friends of theirs who are clearly at much higher level of the sport and ask them to play the play-offs and finals (these same people have never played on the league previously).

Played a whole season with no basketball nets, and when people had reached out to request to push the venue to have them fixed, they were told it will happen but never did. The only time the nets got fixed was when players bought the nets themselves and had it fixed. Multiple games were also cancelled back to back in the recreational and intermediate leagues.

Customer service also lies to you and when you call them out for lying, they get defensive and make up stories. Unsure whether phone calls are recorded, however they should be moving forward for the sake of accountability.

The only people that seem to really enjoy the leagues, are people who aren't too interested in having good quality games, but just want to show up and play. You would find that many players within the leagues would also have 1-star opinions, but don't bother to speak up.

Incredibly frustrating company to deal with, midway through a season and we have not had any games since 09/09/25. I have asked for a refund for the remaining games multiple times to just be given a copy of their terms and conditions. Terms and conditions don't negate consumer rights.

Have been enjoying the GoMammoth league in various locations around London.
Staff and refs have been very helpful and accommodating.

Always great fun and have made some life long friends at Go Mammoth

I signed to a basketball league up as an individual and wehave now just completed our sixth season together! Each one has been organised well, with a mixture of teams, some of which we have built up a friendly rivalry. Each league has been friendly. well referee'd and accessible. It's great to see stats, table and fixtures easily on the website. Would definitely recommend for someone wanting to try out a new sport.

Very friendly team and they made the game extremely fun and enjoyable!

Great way to keep fit and socialise as an adult

Only recently discovered Go Mammoth through a friend and it’s such a great concept! Great way to get active in a fun way and meet a new bunch of lovely people. Everyone is super friendly and so supportive so 100% worth it. All the contact re: games is early and straightforward!

Terrible for basketball.
Disorganised, lack of communication, and the only referee the assign to the games seems to be a random guy who's just looking forward to finish the night and get some extra money. You end up paying a lot for a 30 min game, where they don't even bother to stop the time.
London deserves so much better than this.

Great Experience

GoMammoth is a social sports organisation that uses contract refs and helps place teams in leagues and people in teams. Things will not always go right 100% of the time - that is the nature of social, recreational things!

People run late, bad weather happens and people have last minute life encounters.

If you have an open mind, and take it for what it is, GoMammoth is absolutely wonderful at creating times and spaces for people to play social, competitive sports, with rules and guidelines to keep everyone safe.

I have had a fantastic experience, met great people and played lots of netball with them. Some days, things have not gone to plan. People showed up late, or an umpire forgot her whistle - but these things happen!

I am both a player and an umpire with GM and recommend 10/10.

I had really wanted to join a netball league and I decided to try out Go Mammoth. I thoroughly enjoyed my first session. The team were all incredibly welcoming and supportive. The umpire was great too. I’m already looking forward to my next session.

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
