Rehabilitation and physiotherapy provider Metis is to launch a national network of treatment centres.
Chairman Ronnie Truss said the company, which currently has two treatment centres in London, was "a long way down the road" in negotiations to open two City centres within the next few months.
The company also planned to open centres in Birmingham and Manchester before the end of the year, and had identified several potential sites, according to Truss.
"Once the City offices are open we will be able to go to the insurance companies, as we will have a mass of clinics within this area, and start to work with insurers directly," said Truss.
Truss said he had contacted a number of insurers who responded positively to the idea. At present, 60% of the cases seen by Metis are covered by insurance. Truss said he expected that number to rise to 70% once the company began dealing directly with insurers.
The company had a turnover of £1.5m at the end of 2004, but Truss said he expected this to rise to £4m by the end of 2005, when the new centres were open.
