It secured tenders in three new areas, Craven, Hambleton and Richmondshire, and renewed deals in Harrogate and Selby.
The success follows offering an award-winning service in Harrogate since 1989 and Selby since 2001.
In the last five years these services have benefited over 32,000 residents.
Yorkshire Housing’s deputy head of home improvement agencies Kate Haley said:
“We’re delighted to be able help more vulnerable residents remain independent in their own homes.
“We have a great team who are committed to going the extra mile for our customers.
“It is this enthusiasm which shone through and helped us secure the contract.
“We are always looking at ways we can develop and improve the service.
“For example, earlier in the year we launched a paid-for service HandyTec. This has broadened access to HIA so customers who do not qualify for funding can still benefit.”
Coun Clare Wood, North Yorkshire County Council’s executive member for Health and Adult Services, said:
“Providing the support and care to allow people to live full and independent lives in their own homes is a key part of the council’s vision for older people.
“We welcome the added assurance provided by these new contracts from Yorkshire Housing’s Home Improvement Agency.”
HIA helps older people and other vulnerable customers continue to live independently by adapting their home.
This ranges from fitting grab rails to providing a level-access shower.
The Handyperson service offers assistance with odd jobs such as assembling furniture or fitting light bulbs.
HIA also provides a free, independent advice service to prevent accidents at home and help with accessing benefits, grants and winter fuel payments.
Last year Harrogate-based Needs, Advice and Support officer Maggie Partridge was highly commended in at the Foundation Awards for raising over £82,500 in charitable and benevolent funding for customers.
