What are the best duvets to buy in the UK?
Our top pick for Duvets in the UK is the Silentnight All Seasons 3 in 1 Double Duvet, 4.5 + 10.5 Tog.
The Silentnight All Seasons 3 in 1 Double Duvet suits buyers who want one purchase for every season: the listing states a 4.5 tog and a 10.5 tog duvet that combine to 15 tog, Fibadown fibres and a 5-year manufacturer's guarantee.
The Silentnight All Seasons 3 in 1 Double Duvet is our top pick because its listing states a 4.5 tog and a 10.5 tog duvet that can be used separately or combined to make 15 tog, with down-like Fibadown fibres, a box-stitched design and a 5-year manufacturer's guarantee. For a summer duvet on its own, the Silentnight Anti Allergy 4.5 Tog is sold as a lightweight summer quilt; for one all-year double, the Slumberdown Anti Allergy 10.5 Tog states 200 x 200cm and machine washing at 40°C.
This guide compares five duvets from Silentnight, Slumberdown, SleepyNights and Siebenschläfer on what each listing states: tog rating, size, filling and cover, washing and guarantee. Stated tog ratings run from 4.5 (Silentnight Anti Allergy) to 13.5 (SleepyNights), or 15 when the two Silentnight 3 in 1 duvets are combined.

Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Every listing here states a tog rating, and two give full dimensions in their titles: the Slumberdown (200 x 200cm) and the SleepyNights (135 x 200cm). Washing temperatures appear on two listings, Siebenschläfer (95°C) and Slumberdown (40°C), and the SleepyNights and Siebenschläfer listings state no guarantee term. Two titles carry the words Allergy UK Approved: the Slumberdown Anti Allergy and the Silentnight Anti Allergy.
Our Take
As a default, pick the Silentnight All Seasons 3 in 1: a 4.5 tog and a 10.5 tog duvet that combine to 15 tog, and a 5-year manufacturer's guarantee, all on the listing. For summer on its own, the Silentnight Anti Allergy is 4.5 tog and sold as a lightweight summer quilt; for a single bed in winter, the SleepyNights lists 13.5 tog at 135 x 200cm.
