Enhanced Warranty Package: £125.00 including VAT
Considering buying an electric wheelchair, mobility scooter, electric rise and recline chair, bath lift, hoist or electric profiling beds?
As manufacturers’ warranties do not in general include callouts and labour, we highly recommend our “12 Months Enhanced Warranty Support " which covers the cost of call outs and labour to diagnose faults and fit warranty parts for up to 3 call outs in year one.
Should your product develop a fault we will always try to diagnose the problem by telephone to provide the quickest solution.
If you opt in to the enhanced warranty support we will appoint a competent person to call out and fit parts under warranty and there would be no charge incurred for the call out and labour.
If you don’t opt in to this service, we can either despatch the parts via courier for you to appoint your own fitter or we would offer to arrange a chargeable call out for an engineer to visit.
This enhanced warranty option doesn’t cover the cost of call outs and labour to repair or fit parts not covered under warranty due to damage or customer misuse. In the event of non warranty parts requirements labour and call outs are chargeable at the standard rate.

Some of our products will require installation by a qualified person such as a plumber, electrician or engineer. This includes the installation of Stairlifts, overhead track hoists, Biobidet toilet washers, level access shower trays and our range of bath tubs.
