Tottenham Hotspur Supporters' Trust has accused the club of pricing out fans following season ticket pricing announcements on Monday.
Spurs announced that the cheapest option for the first season in their new stadium next term will be £795, with prices rising to £1,995 in other parts of the ground.
The trust said in a statement that it has urged the club to rethink their pricing structure, adding that it is prepared to host open dialogue over supporter concerns.
"Some fans will be paying £880 more than they did at White Hart Lane if they wish to continue having a seat on the side," the statement read. "Fans watching from behind the goal will have to pay at least £200 more than they did at White Hart Lane. In any terms those are price rises.
"We remain committed to a full dialogue with the club as soon as it is ready to properly address supporter concerns. In the meantime, we will be considering other methods of encouraging change."
Tottenham provided an update on the season ticket renewal process via their website, saying: "It is natural that supporters relate the old with the new however there is no like-for-like seat comparison anywhere within the new stadium.
"All seats have uninterrupted views, comfortable modern seating, more leg room, with spectators closer to the pitch than at any other comparable ground in the UK as well as a significantly enhanced experience for every spectator on concourses."
Spurs face Swansea City on Saturday in an FA Cup quarter-final in South Wales.
