How to Choose the Right Duvet Tog for Every Season (UK Guide)

Choosing the right duvet tog makes a bigger difference to sleep quality than most people realise. The tog rating affects warmth, breathability and comfort throughout the year, and the ideal choice changes with the seasons, your home’s insulation and even your personal sleep temperature. This guide explains everything you need to know to pick the perfect duvet for every month in the UK climate.

🌡️ What “tog” actually means

A tog rating measures thermal insulation—how well a duvet traps heat. Higher tog = warmer. Lower tog = cooler.

The filling type (feather, down, microfibre, hollowfibre) affects weight and feel, but the tog rating determines warmth.

❄️ Winter duvet togs (cold months: November–February)

Recommended: 13.5 tog or 15 tog Best for:

• Cold sleepers
• Older homes with draughts
• Rooms that drop below 16°C at night

A high‑tog duvet provides maximum insulation and is ideal for the coldest part of the UK winter.

🍂 Autumn & early spring duvet togs (mild months: March–April, September–October)

Recommended: 10.5 tog Best for:

• Most UK households
• Couples with different sleep temperatures
• Homes with moderate heating

A 10.5 tog duvet is the most versatile and popular choice for year‑round comfort.

☀️ Summer duvet togs (warm months: May–August)

Recommended: 4.5 tog or 7.5 tog Best for:

• Warm sleepers
• Well‑insulated homes
• Bedrooms that stay above 20°C

A lightweight duvet prevents overheating and improves airflow during warmer nights.

🌦️ All‑season duvets (best of both worlds)

Recommended: 3‑in‑1 or “all seasons” duvets These combine two duvets—typically 4.5 tog + 9 tog—that can be used separately or clipped together to create a 13.5 tog winter option.

Perfect for:

• People who want one purchase for the whole year
• Guest rooms
• Homes with fluctuating temperatures

🛏️ Tog recommendations by sleeper type

Cold sleepers: 13.5–15 tog Hot sleepers: 4.5–7.5 tog Couples: 10.5 tog or an all‑season set Children: 4.5–7.5 tog (never high‑tog for safety) Older adults: 10.5–13.5 tog depending on home temperature

🧵 How filling affects warmth and feel

• Excellent insulation
• Soft and lofty

• Hypoallergenic
• Easy‑care and washable
• Slightly heavier feel

Cotton-filled duvets:
