Most homes in Scotland with central heating run on gas rather than electricity, and gas central heating is generally cheaper to run than standard electric heating, because gas has historically cost significantly less per unit of energy than electricity. That said, ‘electric heating’ covers a wide range of options from old-fashioned storage heaters to modern electric heat pumps and the efficiency comparison changes depending on which type you’re actually comparing gas against. In our experience, most Glasgow homeowners asking this question are really deciding between sticking with a gas boiler, switching to electric storage heaters, or investing in a heat pump, so it’s worth looking at all three properly rather than treating ‘electric’ as one single option.
Is Central Heating Gas or Electric?
In the UK, central heating almost always refers to a gas-fired system: a boiler heats water, which is then pumped around the house through pipes to radiators or underfloor heating. It’s called ‘central’ because one appliance heats the whole property from a single point, rather than each room having its own separate heater. Electric heating works differently instead of one central boiler, electric systems either heat individual rooms directly (panel heaters, storage heaters) or use an electric-powered heat pump to move heat into a similar pipe-and-radiator system.
How Gas Central Heating Works in a Glasgow Home
A gas boiler burns natural gas to heat water, which circulates through radiators and, in some homes, an underfloor heating system. Most Glasgow properties, from tenement flats to modern new-builds, are set up this way because mains gas has been the standard heating fuel across Scotland for decades, and the infrastructure gas pipes to the property, a chimney or flue outlet is already in place in the vast majority of homes.
How Electric Heating Works
Storage Heaters and Panel Heaters
These heat individual rooms directly using electricity, with no boiler or central pipework involved. Storage heaters build up heat overnight on cheaper off-peak electricity tariffs and release it through the day; panel heaters simply convert electricity to heat on demand, which tends to be the most expensive way to heat a home.
Electric Heat Pumps
A heat pump is a different proposition entirely. Rather than generating heat directly from electricity, it extracts warmth from the outside air or ground and moves it indoors, similar in principle to a fridge working in reverse. Because of this, a heat pump can produce three or four units of heat for every one unit of electricity it uses, which puts its running efficiency in a completely different category to a storage heater. Our Central Heating vs Heat Pump guide covers this comparison in more depth if you’re specifically weighing up a heat pump against your existing gas boiler.
Running Costs: Gas Central Heating vs Electric Heating in Scotland (2026)
Costs shift with wholesale energy prices, so treat these as a general guide rather than a fixed number Ofgem publishes the current price cap if you want up-to-date unit rates. As a rough comparison for an average three-bedroom Scottish home:
| Heating Type | Typical Annual Running Cost (2026) |
| Gas central heating (combi boiler) | £900 – £1,400 |
| Electric storage heaters | £1,600 – £2,400 |
| Electric panel heaters | £2,200 – £3,200 |
| Air source heat pump | £800 – £1,300 |
These figures assume typical usage and a reasonably well-insulated home actual bills vary with house size, insulation, and how the system is used.
Efficiency Compared
A modern gas boiler typically converts around 92 to 94% of the gas it burns into usable heat, which is genuinely efficient very little is wasted. Panel heaters and storage heaters are close to 100% efficient at converting electricity into heat, but that figure is misleading, because electricity costs several times more per unit than gas in the UK, so the higher ‘efficiency’ doesn’t translate into a cheaper bill. Heat pumps flip this again: because they move existing heat rather than generating it from scratch, they can deliver 300% to 400% efficiency in energy terms, which is why, despite electricity being more expensive per unit than gas, a heat pump can still end up cheaper to run than a boiler in a well-insulated home. Keeping any system serviced properly also protects its efficiency and running costs over time, whichever type you choose.
Government Grants and Incentives
If you’re considering switching away from gas, several schemes exist to offset the upfront cost. The UK Government Boiler Upgrade Scheme offers a grant toward the cost of installing an air source or ground source heat pump in place of a gas boiler. The Energy Company Obligation (ECO4) scheme also supports energy efficiency upgrades for eligible households, often alongside insulation improvements that make any heating system perform better. For Scotland-specific support and guidance, Scottish Government and mygov.scot both publish current home energy schemes and eligibility criteria, since support can differ from the rest of the UK.
Which Is Right for Your Home?
- Already on mains gas with a working boiler: sticking with gas central heating is usually the most cost-effective option short to medium term
- No mains gas connection (rural or off-grid properties): a heat pump is often more competitive against electric storage heaters than against gas
- Well-insulated, newer-build home: a heat pump can be genuinely cost-competitive with gas and comes with a lower long-term carbon footprint
- Older, poorly insulated property: gas central heating typically remains cheaper to run until insulation is improved, since heat pumps perform best at lower, steadier temperatures
Glasgow-Specific Considerations
The vast majority of homes we work on across Glasgow city centre, East Kilbride, Paisley, Hamilton, Motherwell, and Rutherglen are already on mains gas, which keeps switching costs down if you’re staying with a boiler. Older tenement flats can be trickier and more expensive to convert to a heat pump system because of space constraints for external units and the need for larger radiators or underfloor heating to work efficiently at lower temperatures, so it’s worth getting a proper assessment before assuming either option is automatically cheaper.
Why Choose a Gas Safe Certified Engineer?
Whether you’re keeping gas central heating or considering a switch, any work on a gas boiler must be carried out by a Gas Safe registered engineer it’s a legal requirement, not just good practice, and it’s the only way to guarantee the appliance is installed and maintained safely. A properly registered engineer can also give you an honest, unbiased comparison for your specific home, rather than steering you toward whichever system they happen to sell.
Frequently Asked Questions
Is central heating gas or electric in the UK?
In the vast majority of UK and Scottish homes, central heating runs on gas. Electric heating systems exist too, ranging from storage heaters to electric heat pumps, but ‘central heating’ most commonly refers to a gas boiler and radiator system.
Is it cheaper to heat a house with gas or electricity in Scotland?
Gas is generally cheaper per unit of energy than standard electricity, so a gas boiler usually costs less to run than electric storage or panel heaters. Electric heat pumps are the exception, since their high efficiency can make them cost-competitive with, or cheaper than, gas.
Does central heating use gas or electricity to actually run?
A gas central heating system uses gas to heat the water but still needs a small amount of electricity to run the pump, controls, and ignition. The bulk of the running cost comes from the gas rather than the electricity.
Are heat pumps worth it in Scotland?
For a well-insulated home, especially one without a mains gas connection, a heat pump can be genuinely cost-effective and is supported by government grants. For an older, less insulated property still on mains gas, a traditional boiler often remains the more practical choice for now.
What grants are available for switching from gas to electric heating in Scotland?
The UK Government’s Boiler Upgrade Scheme offers a grant toward heat pump installation, and Scotland-specific support is available through the Scottish Government and mygov.scot, alongside the wider ECO4 energy efficiency scheme.
Can I switch from gas central heating to electric without major work?
Switching to a heat pump usually requires larger radiators or underfloor heating and sometimes better insulation to work efficiently, so it’s rarely a simple swap. A proper survey from a qualified engineer will tell you what’s realistically needed for your specific property.
