Liverpool waterfront is ranked with the Taj Mahal
If they join the United Nations list, the sites will rank alongside such places as the Great Wall of China, the Grand Canyon and the Taj Mahal.
Chris Smith, the Secretary of State for Culture, Media and Sport, announced the final list of British nominations, which will be considered by the United Nations Educational, Scientific and Cultural Organisation (Unesco) over the next five to 10 years.
Two of the 25 sites will be formally nominated this year - the Blaenavon Industrial landscape in South Wales, and the town of St George in Bermuda. The Dorset and East Devon Coast and New Lanark, south Lanarkshire, will be nominated in 2000.
Mr Smith said last August that Britain's industrial, cultural and scientific influence on the world was inadequately represented, and it is hoped that the final list of proposals will rectify that gap. The Cornish Mining Industry, the Forth Rail Bridge and the Chatham Naval Base in Kent are also on the list.
The World Heritage Convention was adopted by Unesco in 1972, and has been ratified by 147 states.
The first UK list was submitted in 1986 and there are now 17 British sites accorded heritage status, including Stonehenge, the City of Bath, Durham Cathedral and Castle, and Hadrian's Wall.
World Heritage status means the Government is answerable to the international community for ensuring that the sites are maintained to high standards.
Maria Glot, the publicity officer for the 19th-century village of Saltaire, near Bradford, which is also on the list, said she was delighted. "We have worked so hard for this and it is really deserved," she said.
Saltaire, on the banks of the River Aire and distinguished by cobbled streets, almshouses and period-piece public buildings, was established by the mill owner Sir Titus Salt in 1853. It receives nearly a million visitors a year.
But a spokesman for British Waterways, which had hoped that the 200-year- old canal system would be nominated, said it was disappointed by the decision: "Half the population of Britain lives within five miles of our historic canal network and, of all heritage structures, few have had - or continue to have - such a huge impact in shaping a country's landscapes and communities.
"We hope it is only a matter of time before Britain's canals are given the international recognition they deserve."
Mr Smith said that places which had not made the final list may be nominated when the list was up for review in five years' time.
