Scores of jobs are at risk at the Construction Industry Training Board (CITB).
The body, which runs the sector’s own skills levy, has announced plans to change 66 roles and cut a further 46.
It is making more of its services available online and by phone as it seeks to modernise to maximise its benefit to business.
The government has announced plans for a UK-wide skills tax, and has consulted on the possibility of scrapping the CITB levy.
The CITB said in a statement this week: “Currently not enough employers benefit from CITB funding and support and many find the organisation too slow and difficult to deal with.”
It said the next stage was “to reach many more employers through online services, improved phone support, and face-to-face services via a refocused CITB advisor role”.
Collective and individual consultation is taking place with staff affected.
CITB director of policy Steve Radley said: “Too often, our engagement with employers has focused on navigating CITB’s processes rather than looking at what they need.
“This new CITB advisor role, complemented by online chat, extended phone hours and simpler online processes, mean we will be able to support many more employers with advice and funding.
“These reforms are designed to give the industry maximum return on levy investment, and a much better service from CITB. Employers will start to see the difference in 2016 and our aim is to have many more construction firms not only engage with us, but get the funding and support they need.”
