Extended Christmas returns 

Any machine purchases made online on dyson.co.uk or in store at a Dyson Demo Store or mall Demo Zone (on floorcare, hair care and lighting) between 30 October and 24 December 2026 can be returned up until 31 January 2027.

This extended returns policy does not apply to individual accessories and spare parts sold separately and not purchased together with a machine, for which our standard 35-day returns policy applies. If you purchased any additional accessories bespoke to your model together with your machine within the same order, you may also return these together with the machine and get a refund. If you are returning a machine purchase that included bundled or complimentary accessories, these must also be returned at the same time to qualify for the refund.  

For purchases of any Dyson products from third party retailers the seller’s returns policy applies.  

For purchases made from 25 December 2026 onwards, our normal returns policy of 35 days will apply. Please click here to use our self service return portal.  

Please note we offer a 14-day returns policy, in case you change your mind (on purifiers, fans, heaters, cosmetic products and cleaning solutions). You may cancel up to 14 days after receiving your machine.

Oral Care

We offer a 35-day returns policy for sealed products.  

• Products may only be returned if the hygiene seal remains intact.  

• The hygiene seal is considered intact where the product box has not been opened and at least one tamper seal remains unbroken.  

• Once the hygiene seal has been broken, the product is no longer eligible for return due to hygiene considerations.  

Toothpaste and mouth rinse

We offer a 14-day returns policy on our oral care formulations:  

• Only unopened products can be returned.  

• The return shipment costs will be at your expense. These will be deducted from your refund.
