The control centre will deal with calls from across the region
A proposed fire control centre in Cambridge has been lying empty at a cost of £80,000 a month, it is claimed.
When up and running in 2011 the control room will deal with emergency calls from Cambridgeshire, Suffolk, Norfolk, Essex, Bedfordshire and Hertfordshire.
The Fire Brigades Union (FBU) said the new building and restructuring was a waste of money.
The government accepts the project has been delayed, but said the building is being used for training and meetings.
The plan to replace all county-based control rooms with a centralised unit in Cambridge covering the whole region, has been hit by setbacks.
The department of communities and local government said that the "go live" date for the Cambridge centre was now May 2011.
It said the restructuring is necessary to modernise the fire service nationally and equip it "for the demands of the 21st Century".
"The building at Cambridge is still being fitted out but is used for a range of services including meetings and workshops," a spokesman said.
The FBU opposes the plans on the grounds that they would "rob control room staff of vital local knowledge".
Now they claim that the empty building could cost up to £1m a year before becoming operational.
Adrian Clarke from the FBU said: "We have proved time and time again over quite a few years that this project is a waste of money.
"It may not work and it may cost lives yet the government still goes ahead with it and we are at pains to understand why."
