When laundry is slow to dry or a room stays damp, it is tempting to buy a different appliance as soon as energy-bill headlines change. The October price-cap announcement is a useful prompt to review that routine, but its 4% figure is not a 4% increase in the cost of running every electric appliance.
What changes on 1 October
Ofgem’s announcement, published on 26 August, says its typical dual-fuel Direct Debit price-cap figure rises by 4% for 1 October to 31 December 2026. For electricity on a default tariff, it publishes an average unit rate of 26.32p per kWh and a separate 54.83p daily standing charge across England, Scotland and Wales.
Those are averages, not the rate on your bill. Your region, meter, payment method and tariff matter. A fixed-rate tariff does not follow the default-tariff cap change in the same way. Ofgem also says electricity VAT treatment changes on 1 October and warns against directly comparing the two cap periods’ costs. Check the regional and payment-method rates and your supplier’s current tariff before calculating anything.
Start with the job, not the annual headline
If the problem is one bulky weekly load, check the load size, drying space and cycle you actually need. If the problem is a persistently damp room, check where moisture comes from, where the appliance would sit, how its tank is emptied and the ongoing filter or cleaning work. A new machine adds purchase and care costs; the cap headline alone cannot tell you that it is worthwhile.
For a running-cost illustration, a hypothetical 500 W electrical appliance used for two hours consumes 1 kWh: 0.5 kW × 2 hours. At Ofgem’s published October average unit rate, 1 kWh is 26.32p of unit-rate energy. This is arithmetic, not a measurement of any dryer or dehumidifier, a whole-bill estimate, or a comparison with September. The standing charge is separate, and your actual rate and use may differ.
Use the running-cost calculator only when you have a credible wattage and runtime for the same use case; enter your own electricity unit rate. If the manufacturer provides kWh per cycle instead, multiply that figure by your own pence-per-kWh rate separately—the calculator has no kWh-per-cycle input. Do not treat peak wattage as a whole-cycle average. Repeat the check for your actual routine: occasional loads and daily use lead to different totals.
Decide whether buying helps
For a damp room, the dehumidifier shortlist separates extraction formats and the maintenance trade-offs; its exact buying actions are optional, not a recommendation to buy because of the cap. For laundry loads that need a machine, the tumble-dryer shortlist starts with load, space and installation fit before its exact retailer options.

If the existing routine works, keep it. Revisit a purchase only when the real household problem, an exact appliance specification, ongoing care and total delivered cost justify it independently of a percentage headline. No appliance was tested for this article, and neither Ofgem’s averages nor the example establish a saving, payback period or best machine for your home.
