The RFL, governing body for rugby league in the UK, has enhanced its partnership with gas and electricity provider First Utility.
Already the title sponsor of the RFL’s Super League domestic competition, First Utility has been named an official partner of the 2015 International Series.
The three-game series pits England against New Zealand and begins on Sunday.
“We’re big fans of rugby league and our first two years of sponsorship have proven to be very successful,” Ed Kamm, chief customer officer at First Utility, said. “By adding our sponsorship of the international Tests, we feel truly part of the rugby league community.”
