Overview

• Interior expert Chloe Barrow of Laura James identifies Saturday 25 October as the optimal switch date based on recent patterns.
• Her analysis notes an average 3.1°C drop from September to October over the past five years, with October 2024 averaging below 12°C.
• She advises moving to a thicker duvet when temperatures consistently reach 10°C or lower, a level more typical from late October into November over the past nine years.
• Suggested togs vary by home: 9–10.5 for well‑insulated properties, 13.5 for homes with less insulation, and 15 for households without central heating.
• Some outlets report forecasters expect an early‑October warm spell near 25°C, so households may adjust the timing based on local conditions and insulation.
