TL;DR
- Hive is the Centrica-owned smart heating brand. British Gas customers can bundle Hive Active Heating with an energy tariff, with the hardware spread over 12 months on the bill rather than paid upfront.
- Hive savings depend entirely on whether the household actually uses the schedule and geofencing features. Energy Saving Trust data suggests 5 to 10% on heating costs for engaged users; closer to zero for set-and-forget users.
- Hive Mini (a basic thermostat) is around £120 retail. Hive Active Heating (full kit including hub and receiver) is around £229. The bundle spreads the cost on a fixed monthly add-on.
- British Gas's accompanying energy tariff is typically the supplier's standard variable or a 12-month fix. The Hive add-on does not include a discounted unit rate.
- Hive devices work with most combi and conventional boilers but not with all heat pumps. Heat pump owners should check controller compatibility before buying.

The Hive bundle is a Centrica cross-sell. British Gas supplies the energy. Hive Home, a Centrica subsidiary, supplies the smart thermostat. The bundle lets a customer buy the hardware on instalments through the energy bill rather than paying for it upfront at a retailer. That convenience is the main customer-facing feature. The energy supply itself is unchanged from buying the same British Gas tariff without Hive.
What the bundle does not do is discount the energy unit rate. The Hive layer is hardware-financing, not a cheaper tariff.
What Hive actually does to a heating bill
Hive Active Heating turns a conventional thermostat into a programmable, smartphone-controllable one. The headline features are: scheduling by time of day and day of week, geofencing that turns heating off when no household member is home, holiday mode that drops the temperature for a set period, and a weather-compensation overlay for compatible boilers.
The Energy Saving Trust published a smart thermostat impact assessment in October 2024 with a headline saving of 5 to 10% on heating costs for engaged users. Engaged is the key word. Users who set a schedule and use geofencing capture most of the saving. Users who install the device and never adjust the default schedule see saving in the 0 to 3% range.
Hive's marketing claim of up to 31% saving in some scenarios comes from the comparison of optimised use against a household with no thermostat control at all. That is a marketing-grade comparison; the realistic figure for most households is below 10%.
For a household with a typical gas bill of £1,000 a year, 5% saving is £50. Set against the Hive hardware cost of £229, payback is around four to five years. Geofencing extends the saving further for households where members are routinely out during the day.
The bundle structure
British Gas offers Hive as a bolt-on to most domestic energy tariffs. The hardware cost is spread over 12 months on the energy bill at no interest. The monthly add-on is £19 (Hive Active Heating) or £10 (Hive Mini). After 12 months the hardware is paid off and the monthly add-on stops.
The energy tariff side of the bundle is one of British Gas's standard products: HomeEnergy Standard (the standard variable, cap-priced), HomeEnergy Fixed (12-month fix), or HomeEnergy Bonus (cap-priced with bill credit perks). The Hive add-on does not change the energy unit rates.
Below is a sample bundle cost breakdown for a medium-consumption household, Q1 2026 rates, Eastern region.
| Component | Standalone | British Gas Hive bundle |
|---|---|---|
| Energy (annual, cap-priced) | £2,166 | £2,166 |
| Hive Active Heating hardware | £229 retail | £19 x 12 = £228 |
| Boiler service (optional add-on) | £85 retail | £85 if added |
| Smart Plug, additional bulbs | £15-30 retail each | Add to bundle ad hoc |
The bundle math says the hardware costs the same either way. The benefit is the cash-flow split: paying £19 a month on the bill is easier than £229 upfront, especially for households already budgeting energy spend monthly.
Installation and the practical setup
British Gas arranges a Hive installation alongside the energy account setup. The engineer fits the receiver next to the boiler, pairs the thermostat to the hub, and tests the system. The fitting takes around 90 minutes. There is no charge for the install when bundled.
For DIY installation (where the customer buys Hive at retail and fits it themselves), the receiver must wire to the boiler's existing thermostat terminals. Most modern combi boilers have a clearly marked thermostat connection. Older or unusual systems may require an electrician.
The catch is heat pumps. Hive Active Heating was designed for gas combi and conventional boilers. Heat pumps with their own weather-compensation controllers (Vaillant aroTHERM, Mitsubishi Ecodan, Daikin Altherma) generally do not benefit from a Hive overlay; the manufacturer's own controller manages flow temperature more effectively than a simple on-off thermostat.
British Gas does not currently bundle Hive with its heat pump installations. Customers fitting a new heat pump should plan to use the manufacturer's smart control, not Hive.
Hive's other devices and the wider ecosystem
The Hive range extends beyond the thermostat. Hive View is an indoor security camera. Hive Active Lights are smart bulbs. Hive Smart Plugs are mains plug controllers. Hive Motion Sensors and Window/Door Sensors integrate into the heating ecosystem.
The wider ecosystem can deliver additional savings when zoned properly. A motion sensor in a rarely-used room can trigger zone-off behaviour; a window sensor can pause heating when a window is open. These features require Hive's premium subscription tier (£3.99 per month for Hive Plus), which is separate from the energy bundle.
Most customers do not need the full ecosystem. The thermostat alone delivers most of the energy saving.
Hive vs Nest, Tado, and Honeywell evohome
Hive is one of several smart thermostat options in the UK market. Nest (Google) and Tado are the main competitors at the consumer end; Honeywell evohome targets multi-zone whole-house control.
Nest costs around £220 retail and integrates well with Google Home. Tado is £200 to £280 depending on package and has the strongest zoned-control feature set, particularly with TRV (thermostatic radiator valve) integration. Honeywell evohome is the premium option at £500 to £800 for a multi-zone install, aimed at larger homes where individual room control delivers significant savings.
Where Hive wins is the bundle availability through British Gas. Customers who do not want to source hardware separately, and who prefer monthly billing to upfront cost, benefit from the integrated supply-and-thermostat offer. The hardware itself is functional rather than market-leading.
Where Hive loses is feature depth. Tado's zoned TRV control and Honeywell's whole-house programming are stronger for larger or more complex homes.
When the bundle is the wrong move
The Hive bundle is the wrong move for households that already have a smart thermostat installed, for renters whose landlord controls the heating system, for households where heating is purely electric storage (Hive does not control storage heaters), and for properties already on a heat pump with a manufacturer's smart controller.
It is also a poor fit for tariff-shoppers who want the cheapest energy unit rate. British Gas's bundle keeps the customer on a standard variable or fix; cheaper tariffs are available elsewhere. A customer who values the lowest annual bill should buy Hive at retail (if wanted at all) and switch to the cheapest energy supplier separately.
For households committed to British Gas anyway and looking at a smart thermostat purchase, the bundle is a reasonable cash-flow option. The hardware cost is no cheaper than buying at retail, but the monthly spread eases the upfront hit.
Where Hive sits inside the Centrica ecosystem
Centrica owns British Gas (the supplier), Hive Home (smart heating), and Centrica Business Solutions (commercial energy services). The group also operates a heat pump installation business (British Gas Heat Pumps), a boiler installation business, and home services contracts under the HomeCare brand.
For the customer, this matters because the cross-sell paths are real. A British Gas energy customer is offered Hive Active Heating when contacting customer service about a boiler issue. A HomeCare customer is offered Hive as part of a wider home services bundle. A new heat pump install through British Gas Heat Pumps will be offered an integrated smart heating layer.
Hive's standalone position in the smart thermostat market has been gradually eroded by Nest and Tado, both of which offer stronger feature sets at similar price points. Centrica's strategy has shifted toward integrating Hive deeply with its services rather than competing on standalone features. The bundle pricing through British Gas is the visible expression of that strategy.
For customers shopping smart thermostats in 2026, the Centrica ecosystem advantage matters most when the customer is already buying multiple Centrica services. A customer taking energy, HomeCare, and a smart thermostat in one bundle gets a coordinated experience that piecing-together products from different suppliers does not deliver. The trade-off is that the individual components are mid-market rather than best-in-class.
One thing the bundle does well that competitors miss
The single most useful operational feature of the British Gas Hive bundle is the unified customer service. A customer with an energy billing question, a thermostat connectivity issue, and a boiler service appointment can address all three in one phone call or chat session. Suppliers that source thermostats from third parties cannot match this; the customer ends up calling the supplier for energy, the thermostat manufacturer for hardware, and the boiler engineer for service.
For households that value time saved on service admin, this convenience can matter more than the unit-rate cost of the underlying energy. The bundle pricing on energy is not market-leading, but the consolidated service experience reduces a category of household friction that many customers do not realise they are spending time on.

FAQ
Does adding Hive to a tariff save money on energy?
Only if you actively use the schedule and geofencing features. Energy Saving Trust data suggests 5 to 10% saving on heating for engaged users.
Is a customer-owned Hive thermostat compatible with a British Gas tariff?
Yes. A customer who already owns Hive hardware can take a British Gas tariff without the bundle. The hardware works regardless of supplier.
Does Hive work with heat pumps?
Often not as the primary controller. Heat pumps usually have their own weather-compensation controller that outperforms a simple on-off thermostat. Check compatibility with the manufacturer before adding Hive.
Is the bundle cheaper than buying Hive separately?
No. The hardware cost is the same. The bundle spreads payment over 12 months at no interest, which is the cash-flow benefit.
What happens to Hive hardware after switching supplier?
The hardware continues to work with any supplier; it is not locked to British Gas. The outstanding bundle balance is settled in the final bill.
Does Hive continue to work after switching away from British Gas?
Yes. Hive hardware is not locked to British Gas. The thermostat continues to work with any supplier; any outstanding bundle balance is settled on final bill.
