⚡Like what you see? This becomes your home.Everything above is one sample home. Connect your own meter and every figure turns into your real numbers — whether you’re overpaying, your cheapest tariff, where your energy actually goes. A few minutes to set up, from £1.50 a month while your meter is connected (£1.50 for one meter, £2.50 for gas and electricity), and nothing sold — I take nothing when you switch.
Ranked on your total cost across both fuels, on your own usage. No supplier pays to appear. Always confirm the live rate before you switch.
Your year aheadshould you fix?
It depends on the cap. Fixing is worth £196 if it rises as far as the top case, and costs £0 if it does not move.

Your year ahead — should you fix?
Your year ahead, on your usage
Likely about £2,492/yr
That’s about £32 more a year than you pay now — roughly £3 a month.
Staying on the price cap, across your gas and electricity. Likely between about £2,453 and £2,649 depending on how far the cap rises this winter.

🔒Locking a fixed rate now can shield you from these risesSee the best deal for your home just below.
Forecasters expect the cap a little higher from October; deep-winter caps are less certain. A 12-month fix locks through winter, when your usage and any rise bite hardest. These are scenarios on this home’s real usage to help you decide, not predictions.

Would solar, a heat pump or air-con pay off here?what it'd cost you, and what it'd save
☀️ Bigger moves
What a heat pump, solar or air-con would mean for youillustration
♨️Heat pump
your 11,466 kWh/year of gas becomes about 3,481 kWh/year of electricity.
→ about £230/year more to run.
If you rip the gas out entirely (no gas hob), it’s £109/year more instead — the gas standing charge is the whole difference.
To break even on running cost at your rates a heat pump needs a SCOP of 3.74. The UK government’s Electrification of Heat trial measured a median of 2.80 in real homes; installers usually quote 3.5–4.0.
This is modelled from your own gas use, not measured — nobody can measure a heat pump you haven't got. Running cost only: it leaves out the install, any grant, and the fact that a well-designed system in a well-insulated home does better than the average. It's the number to start from, not the whole answer.
☀️Solar panels
about 3,400 kWh/year generated; roughly £253/year saved using your own power; about £366/year earned exporting at 15.0p/kWh.
→ about £619/year in total. Rough payback about 10 years.
❄️Air-conditioning
about 450 kWh/year of extra summer cooling.
→ about £119/year added to your bill.
The assumptions —
Solar: a typical ~3,400 kWh/year system, of which about 45% is used in the home and the rest exported at 15.0p/kWh (SEG); install cost about £6,000.
Air-con: about 450 kWh/year of extra summer cooling, costed at your 26.4p/kWh unit rate — this ADDS to your bill.
Your own measured gas use: about 11,466 kWh a year.
Gas boiler running at about 85% seasonal efficiency, so roughly 9,746 kWh of that actually becomes heat.
Heat pump at a SCOP of 2.80 — the measured median from the UK government's Electrification of Heat trial, not an installer's headline figure.
Priced at your own rates: 26.4p/kWh electricity and 6.0p/kWh gas.
You keep a gas hob — so you keep the gas meter and its standing charge, about £121 a year at 33.3p a day. That is what most homes with a gas boiler actually do.
These are illustrative estimates on typical assumptions, not a quote or a measurement of your home. Your real figures depend on your roof, kit, usage and export deal. Solar figures are £/year benefit; air-con is £/year extra cost.
