The Leeds-based company - one of the largest privately-owned facility management providers in the country - will also be prominent across the club’s live first-class online coverage, as well have a significant presence at Emerald Headingley, Scarborough and York.
The company will also provide cleaning and facility management services at Headingley for the next five years.
It comes 24 hours after Yorkshire announced a four-year deal with leading sportswear brand Nike to become their official kit supplier.
Andy Dawson, Yorkshire’s commercial director, said: “We are absolutely delighted and very proud that we will be wearing the NIC brand on the front of the County Championship shirts for the next three years.
“John Spencer (group chairman at NIC Services Group LTD) and his team deserve immense praise on how they have gone about creating such a great culture within a business and put the foundations in place for it to grow so big, so quickly.
“John and his family are huge supporters of Yorkshire County Cricket Club and it’s always a delight to watch a few overs of cricket with them.
“I will never forget when we showed John the County Championship trophy when we won it in 2014 for the first time in 13 years.
“He was overwhelmed with joy and excitement, therefore it seems fitting that his company name is now on the shirt that will be competing to win that trophy once again.”
John Spencer said: “We are delighted with the partnership and we are proud to sponsor this great club.
“On a personal level, I have supported the club since I was a young boy.
“My family and I have so many great memories and friends through our involvement with Yorkshire County Cricket Club, and the club has a very special place in our hearts.”
Yorkshire’s newest partner was recently named in the Financial Times’ 1,000 Fastest Growing Companies In Europe for the second year running due to its significant revenue growth.
Other accolades have included being recognised for the second year running by the London Stock Exchange as one of the ‘1000 Companies to Inspire Britain’.
