Overview
- On his BBC Radio 5 podcast, Martin Lewis says lowering a combi boiler’s flow temperature can trim gas costs by over 9%.
- He advises turning off radiators in unused rooms and fitting reflective panels behind radiators on external walls to reduce heat loss.
- Foil-backed radiator reflectors are cited as a budget option, with a 4m roll listed at £6.38 at Screwfix in recent reports.
- He warns tumble dryers can cost about £1 per load and recommends dehumidifiers as a lower‑wattage alternative for indoor drying.
- He also highlights a clothes‑drying gadget reported to run at roughly 3p per hour, far cheaper than using a tumble dryer.
