Trading Standards officers are warning people to think twice before agreeing to a visit from these people. The work may well be unnecessary, incur an excessive cost and could invalidate any existing Dyson guarantee.
Dyson says in many cases customers are being charged more than originally quoted for the service - which is itself often carried out to a poor standard or with non-genuine parts - and then offered other products to buy. The company believes households are contacted at random in the hope they have a Dyson appliance, before being told it requires servicing.
The firm has also issued a warning to its customers that a genuine Dyson engineer will never cold-call nor visit homes unless the customer has contacted them. Furthermore, a Dyson engineer will drive a van carrying genuine parts and will also wear an easily recognisable uniform.
Anyone believing that they have received a bogus call from an engineer purporting to be from Dyson should contact Consumer Direct on 0808 156 6770.
