Diagnose your problem
How to Choose a Winter Duvet
Four quick questions to find the right one.
Problem
How cold is your bedroom at night?
Think about a normal winter night with the heating off or turned down low.
Recommendation
Chilly but not freezing: a 13.5 tog like the Silentnight Deep Sleep. Very cold, or you always feel the cold: the Slumberdown Chilly Nights 15 tog.
Products
Problem
Do you have allergies or asthma?
Dust mites or feathers make you sneeze, or you wake up stuffy.
Recommendation
Pick a synthetic duvet you can wash at home. The Slumberdown Anti Allergy says it is approved by Allergy UK. Avoid feather and down if feathers bother you.
Products
Problem
Do you only want to buy one duvet for the whole year?
You do not have room to store a summer duvet, or you hate swapping them.
Recommendation
The Slumberdown All Seasons is two duvets that clip together. Use 4.5 tog in summer, 9 tog in spring and autumn, and both together for 13.5 tog in winter.
Products
Problem
Do you want a natural filling?
You like the light, squashy feel of a hotel duvet and do not mind paying more.
Recommendation
The Homescapes Goose Feather and Down 13.5 tog has a cotton cover and baffle box stitching. It costs a lot more than the synthetic picks.

Not for Babies, and Take Care with Electric Blankets
Adult duvets are not for babies. The NHS says to keep a baby’s cot clear of duvets, pillows and loose blankets, and that babies should never sleep with an electric blanket or hot water bottle. If you use an electric blanket under your duvet, follow the blanket maker’s instructions on settings and switching it off, and check it for damage before each winter.
Research Methodology
How We Chose These Products
We have not tested these ourselves. This is desk research, so we have not slept under these duvets or measured how warm they are.
We read Amazon UK listings for 13.5 and 15 tog duvets, the Amazon UK best seller list for duvets, and verified UK buyer reviews about warmth, sweating, clumping and washing. We compared tog, filling, cover, washing advice and where each is made. Prices and ratings are for the double size on the day we checked. We never make up prices or test results.

Frequently Asked Questions
Common questions about winter duvets in the UK
For most people, we pick the Silentnight Deep Sleep 13.5 Tog Duvet. It is warm enough for a UK winter, made in the UK and machine washable. For a very cold bedroom, the Slumberdown Chilly Nights 15 Tog is warmer. For allergies, choose the Slumberdown Anti Allergy, and for one set all year, the Slumberdown All Seasons.
Most UK bedding brands sell 13.5 tog as their winter weight, and the Silentnight listing calls 13.5 tog ideal for winter. If your bedroom is very cold or you always feel the cold, a 15 tog is warmer. If you get hot at night or the heating is on, a 10.5 tog may be enough.
Pick 13.5 tog for a normal UK bedroom that gets chilly at night. Pick 15 tog if the room is unheated, you live in an older or colder home, or you always feel cold in bed. If you share a bed and one of you runs hot, 13.5 tog is the safer choice.
Tog is a measure of how well a duvet keeps your body heat in. The higher the number, the warmer the duvet. It is not a measure of weight, so a feather and down duvet can feel lighter than a synthetic one with the same tog.
It can be in a warm room or for people who overheat. If you wake up sweaty, try a lower tog or a 3-in-1 set like the Slumberdown All Seasons, where you can use just the 9 tog layer.
Both can be warm. Synthetic (hollowfibre or microfibre) duvets are cheaper, easier to wash at home and a better choice for most allergy sufferers. Feather and down duvets feel lighter for the same warmth, but cost more and are not suitable if feathers trigger allergies.
All five picks are sold as machine washable, and the Slumberdown listings say 40°C. A thick double or king duvet needs a large drum, so check your machine first or use a launderette. Dry it fully before putting it back on the bed, as damp filling can smell and clump.
A duvet costs nothing to run, so keeping warm in bed can let you keep the heating lower at night. The Energy Saving Trust says turning the thermostat down by 1°C, from 22°C to 21°C, could save around £120 a year in Great Britain. Your own saving depends on your home and tariff.
Many people do. An electric underblanket goes on the mattress under your sheet, and the duvet goes on top. Follow the blanket maker’s instructions on heat settings and when to switch it off. Our electric blankets guide compares single, double and dual control blankets.
No. The NHS advises keeping a baby’s cot clear of duvets, pillows and loose blankets, and says babies should never sleep with an electric blanket or hot water bottle. Use lightweight blankets or a baby sleeping bag and follow NHS safer sleep advice instead.
