Fast answer: British Gas heat pump tariff rates and who it suits
British Gas heat pump tariff rates and who it suits depends most on your electricity unit rate and standing charge for your postcode, plus when your heat pump runs. It tends to suit homes with high heat-pump electricity use (especially in colder months) and the ability to shift some demand to cheaper periods—if available—while avoiding higher peak rates.
What to look for
- Lower effective cost for the hours your heat pump runs most
- Standing charge that doesn’t wipe out any unit-rate gains
- Clear terms: contract length, exit fees (if any), and payment method
Usually suits
- Homes with a heat pump and electric-only heating costs
- Households home in the day (steady heating) or able to programme efficiently
- People prioritising supplier service bundles—if the price is still competitive
Usually not ideal
- Low electricity use (standing charge dominates)
- Inability to shift usage (if the tariff rewards off-peak use)
- Homes relying on expensive direct electric backup heating often
Important: We don’t publish specific British Gas heat pump unit rates on this page because they vary by region, meter type, payment method and change frequently. Use the quote tool to see live prices for your postcode, then compare against how (and when) your heat pump uses electricity.
Compare British Gas against the market (properly)
The only reliable way to judge whether a British Gas heat pump tariff is competitive is to compare the total annual estimated cost for your home—using your postcode and your expected electricity use (including the heat pump).
You’ll need
- Postcode (rates differ by region and network area)
- Meter type (smart meter / standard)
- Estimated annual kWh (electricity for home + heat pump)
What to compare
- Unit rates for your relevant time periods (if any)
- Standing charge
- Contract terms, fees, payment method options
If you’re moving from gas boiler to a heat pump, your electricity use can rise a lot. A tariff that looks “fine” for a typical household can be poor value once the heat pump is running through winter.
Two realistic scenarios (illustrative numbers)
These examples show how to think about tariff fit. They are not British Gas prices and not a promise of savings.
Scenario A: Good “shiftable” fit
- Home
- 3-bed semi, heat pump, decent insulation, smart controls
- Annual electricity
- ~7,500 kWh (incl. ~4,500 kWh for heating & hot water)
- Usage pattern
- Can pre-heat water and run some appliances in cheaper periods
- What matters
- A tariff that rewards off-peak use and doesn’t punish peak hours too heavily.
Scenario B: Standing charge sensitivity
- Home
- 2-bed flat, heat pump but mild setpoints, lower demand
- Annual electricity
- ~3,200 kWh
- Usage pattern
- Little ability to shift; heating is short bursts
- What matters
- A lower standing charge and consistently competitive single-rate pricing may outweigh specialist features.

How to compare a British Gas heat pump tariff (without guessing rates)
Heat pumps change the “shape” of your electricity demand. A fair comparison looks at when you use electricity, not only the headline unit rate. Use the table below as a decision aid, then confirm with live quotes.
| What you’re comparing | Why it matters for a heat pump | What to check in your home |
|---|---|---|
| Unit rates (single or multiple time periods) | Heating loads can be big; small differences in p/kWh add up across winter usage. | Do you run steady low heat, or short peak bursts? Do you have hot water schedules? |
| Standing charge | It’s paid daily regardless of use; it can dominate bills in low-consumption homes. | If your total electricity use is lower, prioritise standing charge in comparisons. |
| Meter requirements | Some tariff features may rely on smart metering for time-based pricing. | Do you have a working smart meter? Any known issues with half-hourly reads? |
| Payment method | Direct Debit, pay-on-receipt and prepayment can price differently. | Are you happy with monthly Direct Debit? Any constraints as a tenant? |
| Contract length & fees | A tariff can look good today but lock you in if your usage changes or better deals appear. | Check exit fees, end dates, and what happens at the end of the fixed term. |
Quick checklist: who it suits (and who it doesn’t)
Likely suits you if…
- Your heat pump covers most of your heating (less reliance on direct electric backup)
- You can programme steady temperatures and hot water cycles efficiently
- You’re comparing total costs using your real/estimated kWh, not headline claims
- You’ve checked standing charge + unit rate together
Think twice if…
- You can’t access/maintain smart meter readings and the tariff relies on them
- Your heat pump is frequently overridden into expensive backup heating
- You’re a low-usage household and a higher standing charge would hurt
- You might move soon and don’t want to risk exit fees
Costs, exclusions and common pitfalls to watch
Heat pump tariffs can be excellent value in the right home—but the details matter. Here are the most common ways people end up on a tariff that doesn’t match their heat pump.
1) Standing charge shock
Even with a good unit rate, a higher standing charge can negate the benefit—especially in smaller flats or milder-use homes.
2) Peak-rate exposure
If a tariff has multiple rates, using lots of electricity in “peak” hours can cost more than you expect. Heating patterns matter.
3) Smart meter assumptions
Some tariffs rely on smart meter data. If your meter isn’t communicating properly, billing or eligibility can become a headache.
Heat pump performance caveat (COP/SCOP)
Your electricity use depends on how efficiently the heat pump runs (influenced by flow temperature, emitters, insulation, and controls). A tariff can’t “fix” an inefficient setup.
Tenants and switching
Tenants can usually switch supplier if they pay the energy bills, but you should avoid breaking a landlord’s contract (e.g. included bills) and ensure you can access the meter.
Reality check: A “heat pump tariff” isn’t automatically cheaper than a strong standard tariff. The right choice depends on your total kWh and your usage pattern across the day.
FAQs
Does British Gas have a dedicated heat pump tariff?
British Gas’ available tariffs change over time, and what’s marketed as “heat pump suitable” may vary by meter type and region. Rather than rely on a name, compare live options for your postcode and check the unit rates, standing charge and any time-based pricing structure.
Will a heat pump tariff always be cheaper than a normal electricity tariff?
No. Some specialist tariffs can be great value for the right usage pattern, but others can be worse if the standing charge is higher or if much of your use falls into a more expensive time period. Always compare the estimated annual cost using your kWh and postcode.
Do I need a smart meter for heat pump tariffs?
Not always, but many time-based tariffs work best (or only) with smart metering and reliable readings. If your meter is not communicating, you may find it harder to access certain tariff features or to get accurate bills. Check meter requirements before switching.
Can I switch to British Gas if I have a heat pump and solar panels or a battery?
Usually yes, but the best tariff depends on how your solar/battery changes when you import electricity from the grid. If you export power too, you may need to consider export payments separately. Compare tariffs based on your expected import profile and check any export arrangements you rely on.
What should I check before switching a heat pump home to a new tariff?
Check your current contract end date and any exit fees, confirm your meter type, and review how your heat pump is controlled (timers, weather compensation, hot water schedule). Then compare total annual cost using your estimated kWh and look closely at standing charges and any time-based rates.
How do I estimate my heat pump electricity use for comparisons?
If you’ve had the heat pump for a season, use actual meter readings or your in-home display/app to find kWh used. If it’s new, use installer estimates as a starting point and treat results as provisional—weather and settings make a big difference. When in doubt, compare a range (e.g. “lower” and “higher” kWh) to see sensitivity.
Are heat pump tariffs available across the whole of the UK?
Availability can vary by supplier, region, and meter type, and can change quickly. Use your postcode to confirm what’s currently available where you live, then read the tariff terms before you switch.
Is it worth switching electricity supplier if I’m on the Ofgem price cap?
The price cap limits what suppliers can charge on standard variable tariffs, not on fixed deals. Some fixed deals can be above or below the cap depending on the market. For a heat pump home, it can still be worth comparing, because small changes in unit rates can have a bigger impact on annual cost.
