What makes Which? deals different?
Retailers sometimes use misleading ‘was’ and ‘before’ prices to claim their deals are good. Media sites and artificial intelligence (AI) promote deals from retailers – but do they always check them first? We don’t just take retailers’ word for it, we track actual market prices over six months. We share cheapest and average calculations and evaluate products against strict performance benchmarks. So you get good quality at honest prices.
*References to ‘average price' and 'cheapest price' are based on Which? market knowledge and information supplied by our partners. Prices are checked for the six calendar months prior to publication. Not all retailers are included in our checks.

Best Dyson headphone deals
Dyson OnTrac
Average price in the past six months: £449
Cheapest price in the past six months: £178*
Available from Amazon (£200) or compare prices at other retailers below:
- Over-ear
- Noise cancelling (not adaptive)
- Weighs 449g
We like: Excellent build quality
We don't like: App layout confusing
The Dyson OnTrac are wireless over-ear Bluetooth headphones with noise cancellation. They're battery-powered but, unlike some other models, they don’t come with an audio cable which you can plug in whenever this runs out to continue listening.
They look and feel impressive but they’re heavy, weighing in at a hefty 449g. The controls on the headphones allow you to play and pause music, adjust the volume, skip to the next/previous track, answer/end phone calls or turn the noise cancellation on/off.

Best Dyson vacuum deals
Dyson V16 Piston Animal
Average price in the past six months: £700
Cheapest price in the past six months: £587*
- Bagless and cordless stick vacuum cleaner
- 0.4 litre dust capacity
- Weighs 3.5kg
We like: Peace-of-mind allergen retention
We don't like: Small dust container capacity
This flagship cordless stick vacuum cleaner from Dyson uses sensors to detect how much dust is being picked up, and adapts the power accordingly. Dyson’s new ‘All Floor’ floorhead can be used on carpets and hard floors, and its conical brush bars are designed to automatically detangle any long hairs it collects.
It comes with a wall dock, mini turbo brush, combi dusting and upholstery brush and a crevice tool. You can increase the attachments to nine by adding a three-nozzle detail kit. And you can also add Dyson’s Submarine floorhead (sold separately) that mops the floor. Just bear in mind that none of the V16 Piston range’s accessories are compatible with other Dyson vacs.
To find out if this vac is worth the extra spend, read our full Dyson V16 Piston Animal review.
Where can I find Dyson deals?
While Dyson occasionally offers deals directly from their online store, you'll likely find better ones from third-party retailers.
Another thing to consider is buying refurbished Dyson products – it's a great way to save money and shop in a more eco-friendly way.
You can even buy refurbished items with a warranty directly from Dyson. It sells models on the Dyson online store, usually offering £80 to £100 off, and they come with accessories.

How often do Dyson products go on sale?
It's not uncommon to see Dyson's vacuum cleaners go on sale every month, however, it's not so often for hairdryers or hot brushes.
We typically see big discounts around over the holidays, but sometimes you'll find the odd deal here and there, too, such as during Dyson's summer event. We'll keep this page updated with any good deals that we spot.
