Cycle to Work is a salary sacrifice scheme, where you can save up to 42% off a new Bike and Safety equipment. This means the cost is deducted from your salary as a non-cash benefit, so you save on tax and national insurance.
Here at Tredz, we accept Cycle to Work vouchers from all national schemes. For more information click here.
