Individual payments of up to £750 will be made to around 1,800 individuals, amounting to almost half its employees.
The move to offer one-off payments to lower-earning staff follows similar payments by house builders Barratt and Taylor Wimpey, as well as a handful of specialist subcontractors.
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.”
The move comes in addition to paying employees in line with the real living wage, and, earlier this year, investing in a significant overall pay rise for staff.
In addition, as part of its Be Well programme, Galliford Try has ramped up its series of training sessions, tools and resources for financial planning and wellbeing, recognising the important part it plays on overall mental health.
