"The combined association can provide a stronger lobbying and promotional platform as well as run events that focus on their particular business and operational needs,2 said a spokesman.
Combined turnover of the NCF members together with the other BALI major contractors that will be supporting the group is worth over £1bn and they employ around 20,000 staff.
Consultant Bob Ivison said on behalf of the NCF said "We are in an ever-changing political landscape and the NCF can play a significant part in helping to shape the future for parks and green spaces management and maintenance.
"Working with BALI gives the NCF the sound base from which it can move forward and as we operate independently it will allow all sectors of the industry to feel they can link with us."
BALI chief operations officer Wayne Grills said partnering would give a powerful voice to influence the government’s industry agenda.
"The views of the companies represented by the NCF must be heard and considered by the country’s policy makers if our landscape and our industry are to weather the current damaging cuts in public and commercial spending.
"BALI has among its members large and small companies serving all markets. The lobbying power of BALI and the NCF will benefit them all regardless of their size, which is why BALI is very satisfied with the outcome of the discussions."
