A 13.5 tog duvet is the standard British winter weight — warm enough for unheated bedrooms and cold sleepers without the bulk of a 15 tog. This is the tog most UK households choose for November to March. Hollowfibre fill, machine washable, all four sizes.
Who is a 13.5 tog winter duvet for?
Bedrooms with heating off overnight, cold sleepers, homes managing energy bills (a warmer duvet costs nothing per night to run — unlike heating), and anyone whose 10.5 stops feeling warm by December.
Is a thicker duvet always warmer?
Tog measures trapped warmth, not thickness — a well-filled 13.5 outperforms a lofty but loosely filled duvet. If you want maximum warmth, see our 15 tog.

FAQs
What tog is a winter duvet? 13.5 tog is the standard UK winter weight; 15 tog suits the coldest rooms.
Is 13.5 tog warm enough without heating? For most bedrooms yes — it's designed exactly for heating-off-overnight homes. Very cold rooms may prefer 15.
Can I use 13.5 tog all year? It will be too warm for most people from late spring — pair it with a 4.5 for summer.
13.5 or 15 tog — which should I buy? 13.5 for typical UK winters; 15 if your bedroom is genuinely cold (single-glazed, no heating, north-facing).

Buying direct, and talking to a person
Posh Tag is a family-run bedding business on Fieldhouse Industrial Estate in Rochdale, with more than fifteen years in textiles. Orders are picked, checked and packed by our own team rather than passed to a third party, so if something is not right we deal with it ourselves. Email support@poshtag.co.uk or call +44 7414 441213, Monday to Friday 9am to 5pm.
Warmth under you matters too
Most of the cold in an unheated bedroom comes up through the mattress, not down from the air. A thick mattress topper under you does more for a cold bed than another tog over you, and costs nothing to run. Add an extra deep 40cm fitted sheet to fit over both, and a pair of hotel pillows. Orders over £50 ship free, so bundling saves on delivery.
