Stop Heating the Whole Flat — Warm the Sofa Instead
Personal heat on the sofa is often cheaper and cosier than nudging the thermostat for one evening on the couch.
Quick answer
For UK flat sofa nights, keep central heating at a sensible background setting and use a heated throw to warm the people on the sofa instead of heating every room. Pick coverage for one vs two seats, check wash care and safety auto-off, and compare sofa-focused picks in our best heated throw for sofa UK guide (with the broader best heated throws UK roundup for bed/lounge overlap).
Best heated throw for sofa UKUK flats lose heat through single-glazed leftovers, shared walls and under-door gaps. Turning the whole thermostat up so two people can watch TV warm is a blunt instrument: you heat empty bedrooms, the hall, and air that escapes under doors. A better winter habit for lounge nights is personal heat — a heated throw sized for the sofa — while the flat stays at a sensible background temperature.
That is not anti-heating advice. It is zone thinking: keep pipes and people safe with a reasonable baseline, then put watts where bodies are. Draught-proof the worst gaps first if the lounge leaks into a freezing hall (draught hallway fix), then choose a throw with enough coverage for one or two on the sofa.
Why heat the person, not the whole flat?
Thermostats control air temperature in zones you may not be using. A heated throw puts low continuous warmth on your lap and shoulders while you sit still — typically a few hundred watts at peak, used for an evening, versus raising the boiler setpoint for the entire dwelling. Exact bill savings depend on your tariff, insulation and habits; we do not invent £/hour guarantees.
The comfort win is immediate: you feel warm where you sit without waiting for radiators to catch a leaky lounge. Pair with sealing under-door draughts so you are not fighting a cold river across the floor.
What size heated throw do you need for a UK sofa?
One person curled up can manage a smaller throw; two adults sharing a sofa usually want generous coverage (think large / XXL dimensions in our roundups) so edges are not fighting for fabric. Softness and controller reach to the socket matter as much as peak heat settings.

Safety basics before you plug in
Follow the manufacturer: do not fold tightly while on, keep controls dry, use the timer/auto-off, and never combine with damaged wiring. Electric throws are everyday UK kit when used as directed — treat them with the same respect as any heated appliance. Safety notes on the money pages expand this.
