Spend less on energy, without the guesswork.
Straight answers to the real questions. Should you get a heat pump? Will turning the thermostat down actually help? Is a smart thermostat worth it? Plus the products that genuinely cut your bills.
The questions people actually ask.
A quick verdict, the rough numbers, and a plain-English guide if you want the detail. No jargon, no sales pitch.
Great in the right home. Your insulation, radiators and tariff decide whether it beats a boiler on running cost.
Read the guide →Pays off if your schedule varies or the house sits empty in the day. Less so if you already heat carefully.
Read the guide →Down to your roof, how much you use in daylight, and today’s export rates. We show when it stacks up.
Read the guide →The energy saving alone pays back slowly. The real value is comfort, condensation and noise. We show the full picture.
Read the guide →Usually not. For most homes, heating only when you need it costs less than a constant low temperature. We show the exception.
Read the guide →For small and medium portions the air fryer usually wins on running cost. For a big batch, the oven can still make sense.
Compare them →Small changes, steady savings.
Figures are illustrative while we finish our UK running-cost research. Every number will carry its source and the date checked before it goes live, and where good sources disagree we show the range and cite them.
Everything that shapes your home energy bill.
Heat pumps, solar, batteries, EV charging, tariffs and insulation. We write about the products, the decisions and how they fit together, so you can see the whole picture in one place.
Heat pumps
Running cost by SCOP, tariff and your home’s heat loss.
Solar PV
Generation, self-use and what export is really worth now.
Home batteries
Payback with and without solar, on your tariff.
EV charging
Which tariff suits your charging pattern and mileage.
Tariffs
Time-of-use, export and bundled deals, compared like for like.
Insulation & controls
The cheaper moves that change every calculation above.
No black box. The calculation is right there.
The same inputs always give the same answer, because the maths is fixed code, not a guess. You see every assumption and can change it.
Independent by design.
Calculations you can see
Fixed formulas, editable assumptions, versioned. Nothing invented on the fly.
Dated, sourced claims
Grant and tariff figures carry the source and the date we checked them. When they change, we say what and when.
