Exactly. Treat this chat as a smart estimate only, not as professional financial guidance. Always check important details with official sources or a qualified expert before making any big decisions.

Yeah, really good, thanks. Glad to be back. And I think today's one people genuinely need right now, because we're still very much in the thick of winter and bills are — well. They're not exactly cheerful reading, are they.

Completely realistic. And that's the thing — most people assume you need to spend money to save money on energy. New boiler, heat pump, solar panels, whatever. And those things can help, don't get me wrong, but small changes to habits and settings? They deliver real results for nothing. Genuinely zero cost.

Yeah, exactly. Most of what we're covering today, a renter can do just as easily as a homeowner. So — shall we just get into it?

So under the Ofgem price cap — and this covers the first of January to the thirty-first of March 2026 — a typical dual-fuel household paying by direct debit is looking at around one thousand seven hundred and fifty-eight pounds a year. That works out at roughly twenty-eight pence per kilowatt-hour for electricity and six pence for gas, plus daily standing charges on top of that.

They really do. And there is some good news on the horizon — measures from the November 2025 Budget are expected to take around a hundred and fifty pounds off typical bills from April 2026. But even so, energy is still one of the biggest household costs. So. Let's talk about what you can actually do right now, today.

Yeah, heating is the single biggest contributor to winter energy bills. So it makes sense to start there. And the first thing — honestly, the simplest thing — is just turn your thermostat down by one degree.

Just one degree. That alone can cut heating use by around ten percent. Which for a typical home at current prices is roughly ninety pounds a year. From one degree. Which is kind of... wild, when you think about it.

Most people don't. And then on top of that, if your thermostat or boiler has a timer — actually use it. Set the heating to drop while you're out and warm up just before you get home. Don't be heating an empty house.

Very common. And two more quick ones — bleed your radiators if you haven't recently, because trapped air causes cold spots and makes the whole system work harder. And close the doors to rooms you're not using, turn those TRVs — the little valves on individual radiators — down to a low setting. Something like two.

Yeah, really important. UK Health Security Agency guidance is to keep living rooms at around eighteen degrees — especially for older people, young children, anyone with a health condition. And very cold, unventilated rooms can actually encourage damp and mould as well. So — don't sacrifice your health chasing the savings. That's not the point.

—right, and that's a fair assumption for loft insulation or cavity wall insulation, yeah. But we're talking about the free stuff here. And honestly, just identifying and blocking draughts in your home can save around forty to sixty pounds a year on heating.

So — hold a damp hand near gaps around windows, doors, letterboxes, loft hatches, plug sockets on external walls. Or you can use the smoke from a lit incense stick and watch where it moves. The guide does say avoid using a candle near curtains or blinds, which — [laughs] yeah, obvious when you think about it, but worth saying.

And for blocking them — rolled-up towels or old blankets at the bottom of doors, that's completely free. There's also self-adhesive foam strip for gaps around windows, which is only a few pounds from a DIY shop. And — oh, one big one. An unused chimney is one of the biggest sources of heat loss in a home. Blocking it is often the single most effective draught-proofing fix you can do.

It's a huge one. And curtains — open them during the day to let sunlight warm the room, close them at dusk to trap the heat. And tuck long curtains behind the radiator rather than draping them over it, because if they're hanging over the front you're basically just heating the curtain.

It's a smaller one, to be fair. Um — keeping windows clean, rearranging furniture so light flows freely into the room, using lighter-coloured walls and furnishings to reflect daylight. The savings are roughly ten to twenty pounds a year — more if you still have older halogen or incandescent bulbs rather than LEDs.

Exactly. It's not going to transform your bill on its own. But it's a free bonus, and — honestly — natural light just lifts your mood. So not a bad thing regardless.

Massively. The phrase I always come back to is — you can't cut what you can't see. If you have a smart meter, use the in-home display or your supplier's app to see your usage in near real time. You can actually spot when your consumption spikes and — and do something about it.

Free to request from your supplier, yeah. And even without a smart meter, just keeping a record of your bills, looking for patterns — that alone can save around thirty to fifty pounds a year. But the bigger benefit, I think, is that monitoring makes every other tip in this list easier to measure. You can actually see if something's working. Does that make sense?
