The team will be joining other BIBA broker offices in the region to raise vital funds for the charity which needs £4.4m a year to keep both its helicopters in the air.
Staff will be counting their miles throughout September and making a contribution depending on how many miles they clock up.
With more than 200 BIBA offices in the region, the ‘Walk Around the World’ challenge is on to raise a total of 5,000 miles for the charity.
Lexelle managing director Sharon West said: “We’re delighted to be helping out such an important cause and will be doing all we can to raise as much money as possible.”
A total of £1,485 has already been raised at BIBA’s Yorkshire and Northern Annual Dinner in April and the office which raises the most money will be given a VIP tour of the YAA headquarters.
