ABOUT 50 jobs could be lost at the New Linx Housing Trust.
Its parent company, Waterloo Homes, which is based in the Birmingham area, plans to centralise its "back office" services in the West Midlands.
There are about 50 personnel at risk in finance and human resources services out of the 220 staff working for New Linx in Louth and Skegness.
Employees have received letters telling them of the changes due to come into effect in May.
Tenants in the 6,000 homes looked after by New Linx throughout Lincolnshire will also receive letters informing them of the impact of changes to housing benefits and the new structure.
The centralisation could mean a significant number of job losses at the partnership, which is based at Keily House, in Stewton Lane, Louth.
Waterloo Housing Group chief executive David Pickering told the Grimsby Telegraph: "We anticipate that nearly 150 of our 'front-line' – or customer-facing – staff will continue to have a base in our local office in Lincolnshire and, or, be home-based."
New Linx provides a mix of flats, bungalows and houses for rent in an area stretching from Holton-le-Clay in the north down to Wainfleet.
The trust also built the £4.5 million Elizabeth Court sheltered accommodation complex in Church Street, Louth, pictured below, as well as more accommodation for elderly people throughout East Lindsey.
Mr Pickering said: "The group needs to be ready for changes such as welfare reform, which will have a significant impact on associations such as ours and many of our customers from April 2013.
"We have gone a long way in achieving greater consistency in service delivery for customers. We feel now is the right time to bring our back office functions together in one location."
The new centre is in Solihull and is expected to be operational by December.
"We are in the process of a detailed consultation about our plans with staff over the next few weeks."
He said 311 new homes will be built in Lincolnshire by 2015, with plans for a further 300 after that.
The housing provider was established nearly 15 years ago following the sale of the council housing stock by East Lindsey District Council.
One member of staff who has been with the housing association from the start said: "Everyone is very worried. Many of us have mortgages and if we lose our jobs many of us will be putting For Sale signs outside our homes."
Another staff member, who did not wish to be named, said: "If you are in an admin job in Louth earning around £15,000, you are not going to relocate to the West Midlands. It is an anxious time."
