* The referral to a recognised SUNFLEX distributer is only by way of introduction and, whilst we do hope that you choose to use their services, you are under no obligation to do so. Our distributers are experienced in fitting SUNFLEX door systems but they are an independent third party that operates completely seperately from SUNFLEX UK and the terms and conditions of sale will be directly between you and this company. This company will provide you the guarantee and be responsible for any servicing work required. SUNFLEX UK therefore cannot be liable for any losses, costs, charges or expenses caused by any aspect of the contract.
