Galliford Try is to make a one-off cost-of-living payment of £750 to around half its workforce.
Around 1,800 employees will receive the payments, which are in addition to a pay rise for staff earlier this year.
The company has also intensified its series of financial planning training sessions, tools and resources. It is delivering these through its Be Well programme.
The company said it recognised the important part financial wellbeing plays on overall mental health.
Bill Hocking, chief executive of Galliford Try, said: “We recognise that the rising cost of living is challenging many households across the UK and, as a people-orientated, values-driven organisation we are committed to supporting our people through a variety of means. This is just the latest step of many, offering added support where we can make a difference.”
