"We acknowledge receipt of the Iranian paper, and remain committed to a meaningful dialogue to address the concerns of the international community relating to Iran's nuclear programme," a Foreign and Commonwealth Office spokeswoman said in London.
"Our offer of talks on the nuclear issue (made in April 2009) still stands, and we hope that Iran will respond to this as soon as possible."
Foreign Minister Manouchehr Mottaki presented Iran's package of proposals relating to its controversial programme to the envoys of six world powers including Britain in Tehran earlier Wednesday.
Iran "is ready to discuss political, security, economic, cultural and international issues with the other parties, on the basis of respect for the sovereignty and rights of nations, and without pressure and threats," he said in a statement carried by state news agency IRNA.
Mottaki did not reveal the contents of the package.
Western governments and Israel have accused Iran of trying to develop atomic weapons under cover of its civilian programme, a charge Tehran vehemently denies.
World powers have threatened to impose a fourth set of UN sanctions if Tehran fails to hold talks by late September.
