Foreign Secretary William Hague said Iran should "be more realistic about what is necessary" to reach a nuclear deal with major powers.
Hague made the comments shortly after a meeting with US Secretary of State John Kerry in Vienna.
They were joined in the Austrian city by their French and German counterparts for talks about Iran's nuclear programme.
Six months ago, a deadline to reach an agreement was set for July 20.
It is too early to consider extending the talks between Iran and six world powers on Tehran's nuclear programme beyond next week's deadline, though major divisions remain between the two sides, the Foreign Secretary has said.
"It is unlikely there will be a quick breakthrough today but we [...] shall see what scope there is for making a progress before July 20," William Hague told reporters in Vienna.
Foreign Secretary William Hague is expected to give a statement on the current crisis in the Middle East and the progress of the Iran nuclear talks in Vienna.
There are still "significant gaps" between Iran and the Six Powers in its nuclear talks, US Secretary of State John Kerry has said, as foreign ministers from Britain, the US, France, Germany, Russia and China met in Vienna to discuss Tehran's nuclear programme.
Mr Kerry's sentiments were echoed by Iranian deputy foreign minister Abbas Araqchi, who was quoted by state television, saying: "Disputes over all major and important issues still remain. We have not been able to narrow the gaps on major issues and it is not clear whether we can do it."
