Every October, UK renters feel a particular kind of dread. The heating clicks on for the first time, the radiators clunk awake — and a week later the smart meter display starts climbing like it has somewhere to be.
This winter stings a little more. On 1 October 2026 the Ofgem energy price cap rose again, taking the illustrative annual figure for a typical household on Direct Debit from £1,663 to £1,723. Same radiators, higher bills.
Here is the unfair part: almost every “save on energy bills” guide assumes you own your home. New boiler. Loft insulation. Wall upgrades. As a renter you cannot touch any of that — it is your landlord’s property. But you are not powerless. Heating and hot water make up more than half of a typical home’s energy use, according to the Energy Saving Trust, and that is the part you fully control. This is the renter’s playbook: everything you can do without landlord permission, without risking your deposit, with honest realistic savings.
Quick answer: how do renters cut energy bills this winter?
Turn your thermostat down by 1°C (roughly £100 a year, per Energy Saving Trust estimates), use the TRV dials on your radiators room by room, draught-proof doors and windows with removable strips, cut showers to four minutes, wash at 30°C, and claim the £150 Warm Home Discount if eligible. If your name is on the bill, you have the legal right to switch supplier — no landlord permission needed.
1. The thermostat: your single biggest lever
Turning your thermostat down by just 1°C can cut heating costs by roughly £100 a year, according to Energy Saving Trust estimates. Actual savings vary with your home and tariff, but the direction is never wrong.
The Energy Saving Trust suggests 18–21°C for most people. What nobody tells you: 19°C feels identical to 21°C after twenty minutes in the room. Your body adjusts — what it notices is stepping from a cold hallway into a warm living room, not one degree on the dial.
Two thermostat truths that save real money. First, cranking it to 25 does not heat the house faster. The boiler runs at the same speed whatever the target; a higher setting just keeps it running longer until you are opening windows. Set the temperature you actually want. Second, use the timer properly. Heat the house for the hour before you get up and the evening you are home — not the eight hours you are at work. An empty flat does not care if it is 14°C.
2. Radiators: the dials most renters never touch
Those little numbered dials on the side of your radiators — thermostatic radiator valves — are free room-by-room heating control. Most tenants never touch them, leaving every radiator at 5, blasting heat into the spare bedroom nobody has entered since September.
Turn down, don’t turn off, unused rooms. Set spare-room radiators to 2 or the frost setting (usually a snowflake symbol). Switching them fully off in a cold snap risks damp and frozen pipes — and damp in a rented flat becomes your problem at checkout.
Bleed them once. Cold at the top, hot at the bottom means trapped air is stopping the radiator working. A radiator key costs about a pound, and the job takes five minutes per radiator.
Slide reflector panels behind radiators on outside walls. Foil strips that bounce heat back into the room instead of warming the bricks. A few pounds, seconds to install, around £18 a year saved per the Energy Saving Trust — and they leave no mark when you move out.
3. Draught-proofing a rented home (no damage, no drama)
Draughts are the silent bill-killer. You can hold the thermostat at a sensible 19°C and still feel cold because October air is flowing under the front door. The fixes are cheap and completely reversible.
Self-adhesive foam strips around window and door frames — peel, stick, done, and they come off cleanly when you leave. Estimated saving: around £55 a year. A draught excluder under the front door plus a brush cover over the letterbox makes an immediately noticeable difference — in one draughty flat I rented, the hallway finally stopped feeling like a fridge.
Close curtains at dusk. Heavy curtains are insulation you already own: open them on sunny days for free heat, close them the moment it gets dark. And keep furniture and curtains away from radiators — a sofa parked against one is an expensive way to warm the back of a sofa.
One caution: never block deliberate ventilation. Extractor fans, air bricks and trickle vents stop damp and mould. Seal the accidental gaps (doors, windows, letterboxes), not the designed ones.
4. Hot water, showers, and the kitchen
After heating, hot water is the next biggest slice of the bill — and renters control it entirely.
Take four-minute showers. That alone can save a typical household around £95 a year on energy bills. One song, then out. Swapping even one bath a week for a four-minute shower saves roughly £20 a year.
Only boil what you need. The kettle is one of the most-used appliances in any British kitchen, and boiling a full kettle for one cup is pure waste — about £10 a year saved for zero effort.
Wash at 30°C, full loads, eco setting. Modern detergents are built for cooler washes. Dry clothes on a rack in a ventilated room rather than the tumble dryer — ditching the dryer can save around £50 a year, and in a rented flat a heated airer uses a fraction of the electricity in deep winter.
On water itself: if your rented flat is an older building with an old cold-water tank and the tap water tastes stale, that is worth understanding separately from the bill. Our friends at Clearove.com cover clean-water basics for homes like these.
5. The money you are already entitled to
Do not skip this section. This is free money, and renters qualify exactly like homeowners.
Warm Home Discount — £150. For winter 2026/27, eligible households get £150 off their electricity bill. In England and Wales you usually qualify automatically if you receive a means-tested benefit and your name is on the electricity bill — but check with your supplier, because “usually automatic” still misses people every year.
Cold Weather Payments — £25 a time. On certain benefits, every seven-day spell of freezing weather in your area triggers £25, paid automatically. No application, no landlord involvement.
Your right to switch supplier. The one renters do not know: if your name is on the energy bill, Ofgem rules let you switch whenever you like. Your landlord cannot forbid it — some tenancy agreements ask you to inform them or switch back at the end, which is fair, but they cannot stop you. If your landlord pays the bill and recharges you, ask what tariff you are on. Clarity is leverage.
Before switching or staying, get your real numbers straight. Plug your actual kWh usage into a calculator at Earnrove.com and see what each change in this guide is genuinely worth to your household — guessing your usage is how people end up on the wrong tariff.
One October-specific job: submit meter readings when rates change. When the cap moved on 1 October, anyone without a smart meter who skipped a reading risked pre-change usage being billed at the new higher rate. Set a reminder for the next change.
6. What to (politely) ask your landlord
Some things are the landlord’s job, and asking costs nothing — frame it as protecting their property, not doing you a favour. The annual boiler service is a legal requirement for gas appliances; an unserviced boiler runs inefficiently, so ask in writing when the last one was. Dead radiators that stay cold at the top after bleeding, or rooms that never warm up, are a system issue — email the agent with photos. And check the EPC rating: since April 2020, rented homes in England and Wales need a rating of E or above, so an F or G rated flat may mean the landlord owes you improvements by law.
5 mistakes that spike renter energy bills
1. Heating the whole flat for one room. Working from home in the living room all day? The bedroom does not need to be 21°C. That is what the TRV dials are for.
2. The portable heater trap. Cheap to buy, brutal to run — electricity costs far more per unit of heat than gas central heating. A heated throw for one person in one room is genuinely cheap; a 2kW fan heater all evening is not.
3. Drying clothes on radiators. It blocks heat from reaching the room, forces the boiler to work harder, and pumps moisture into the air — inviting the damp and mould rented flats are already prone to. Rack, ventilated room, door closed, window cracked.
4. Ignoring the meter. No smart meter? Submit readings monthly. Estimated bills are how suppliers quietly overcharge you all winter.
5. Leaving everything on standby. TVs, consoles, chargers — individually trivial, collectively a real line on the bill. Switched off at the wall costs nothing.
Frequently asked questions
Can renters switch energy supplier in the UK?
Yes — if your name is on the energy bill, Ofgem rules give you the right to switch supplier whenever you like, and your landlord cannot forbid it. Some tenancy agreements ask you to tell the landlord or switch back when you leave, which is reasonable. If your landlord pays the bill and recharges you, you cannot switch — but you can ask what tariff you are on.
What is the Warm Home Discount and do I qualify as a renter?
The Warm Home Discount is £150 off your electricity bill for winter 2026/27. Renters qualify exactly like homeowners: in England and Wales it is usually automatic if you receive a means-tested benefit and your name is on the electricity bill on the qualifying date. Check with your supplier rather than assuming it arrived.
What temperature should I set my thermostat to save money?
The Energy Saving Trust suggests 18–21°C for most people. Dropping from 21°C to 20°C or 19°C saves roughly £100 a year per degree and most people stop noticing within twenty minutes. Do not go below 18°C if anyone in the home is elderly, very young, or has a health condition — comfort and safety come first.
Does turning radiators down in unused rooms actually save money?
Yes, as long as you turn them down rather than fully off. Setting spare-room TRVs to 2 or the frost setting stops the boiler heating space nobody uses. Switching radiators completely off in a cold snap risks damp and frozen pipes, which costs far more than the saving.
Are portable electric heaters cheaper than central heating?
Almost never. Electricity costs far more per unit of heat than gas, so a plug-in fan heater running all evening is one of the most expensive ways to stay warm. The exception is heating one person in one room for a short spell — a heated throw or electric blanket for that is genuinely cheap.
Final thoughts
Renting does not mean surrendering to winter bills. The thermostat, the radiator dials, the draught strips, the shower timer, the £150 discount, the right to switch — none of it needs your landlord’s permission, none of it risks your deposit, and it all adds up. Nobody saves hundreds with one trick; people save hundreds by stacking small ones.
Start tonight: walk through your flat, feel for draughts around every door and window, and turn the thermostat down one degree. Two minutes, pays you back all winter. And while you are in money-saving mode, our guides to saving for Christmas on a tight budget, building an emergency fund on a low income, and the weekly money reset routine will keep the rest of your budget just as warm.
