The Championships was to be London's first major event at the £500m Olympic Stadium following the London 2012 Games.
, yet their plans include making changes to parts of the venue that had been earmarked for the Championship.
The International Association of Athletics Federations (IAAF) is due to decide on the 2015 host city on 20 November - four months before the final decision on the Stadium’s new tenant is expected to be made - leaving the UKA no other option than to postpone its bid.
Chairman of UKA, Ed Warner, said: "Obviously we are disappointed not to be pursuing our 2015 bid especially after securing the support of both the government and the Mayor of London. However, we need to present the IAAF with a bid that is free of any uncertainties.
"That is not something we can commit to until the process regarding the future of the Stadium which we fully support, is concluded. Our bid is, in my option, an excellent one and one that can deliver an outstanding championships for the IAAF. That fact remains."
The UKA says it now plans to focus its attentions on a 2017 bid.
