The Chelsea Supporters Trust are carrying out research into the increased costs and times it may take to reach potential temporary stadiums while Stamford Bridge is rebuilt.
The research is part of a wider, detailed piece of work that the Trust are carrying out around future ticket pricing.
Chelsea have already agreed a deal to use Wembley Stadium as their home stadium for three years starting in 2017-18 on a deal set to cost them £20 million-per-year.
But the Supporters Trust are concerned that there is a danger that the primary focus will only be on the redeveloped stadium and not the temporary home, something they say will have a significant impact on match-going supporters.
Chelsea are looking to redevelop their SW6 home by increasing its capacity to around 60,000 and putting them on a level playing field with Europe’s elite stadia.
Plans were submitted to Hammersmith and Fulham Council at the start of December.
The planning process is expected to last beyond the end of the season, and is expected to be just one of a number of steps towards full consent for the stadium development to go ahead.
Swiss architects Jacques Herzog and Pierre de Meuron have been commissioned by Blues owner Abramovich to transform the west London ground.
Estimates have priced the expansion works at £500 million and will feature a three-tiered stack of terraces and is inspired by the design of Westminster Abbey.
The Trust are aiming to share their findings when the work is complete with both their membership and Chelsea.
