Leinster have confirmed they will play "the majority" of their home games at Aviva Stadium again next season, with Croke Park available as required.
The province have had the same arrangement this season while regenerative works at the RDS continue.
Leinster said on Monday they expect the RDS to be completely finished for the start of the 2026/27 season. It will have a capacity of over 20,000.
"While the RDS Arena will be available to us again from August 2025, we would only be able to operate at a reduced capacity, below what we would need to accommodate our season ticket holders," explained Leinster's chief commercial officer with Matthew Dowling.
"On that basis, we have been working away in the background on different options.
"We have gone from 12,248 season ticket holders two seasons ago at the RDS Arena to now over 15,000 at the Aviva Stadium.
"It's important that we recognise that success, and what it does for the club as well as our ambitions with the RDS, but the focus has to be on getting as many of our supporters as possible to all of our games next year.
"We don’t want to upset or disenfranchise any of our season ticket holders, whether they are with us twelve years or with us twelve months, and we made the decision that we would rather a move back to a completed RDS Arena for all, rather than a move back for only some of our supporters."
