UK commercial outdoor heater costs 2025: gas vs electric - who comes out on top?
In 2025, UK commercial operators faced a clear delta between gas and electric outdoor heating on running costs, with gas typically winning on pure per-hour energy expenditure but electric offering advantages in maintenance, control, and emissions considerations. This analysis uses representative operational data, price points, and historical context to deliver a practical comparison for pubs, restaurants, and events spaces evaluating whether to deploy gas patio heaters or electric alternatives this year. The conclusion for most operators is that gas remains the lower-cost option for sustained outdoor heating in colder months, while electric shines where precise control, speed of deployment, or urban air quality rules constrain fossil fuel use. Operational context matters: fuel prices, efficiency ratings, and usage patterns vary widely by site, making a tailored model essential.
Defining the comparison
Gas patio heaters burn propane or butane canisters or hook up to bottled gas supplies, delivering radiant heat with relatively high output per unit. Electric outdoor heaters convert electricity to heat using coil-based or ceramic elements, offering clean operation and simpler safety profiles. For a fair comparison, we consider typical commercial outdoor usage: peak season operation (roughly 4-6 hours per day), multi-site deployment (up to 4-6 heaters per site), and 42 weeks of operational periods per year. Key metric is running cost per hour (including energy price and heater efficiency), with a secondary view on annualized costs and maintenance.
What drives running costs in 2025
Several factors determine the ongoing cost of outdoor heating in the UK during 2025: fuel price trends, heater efficiency, and operational patterns (hours of use, number of units, and weather-driven demand). Gas prices have fluctuated due to global energy dynamics but typically yield lower hourly running costs for high-output heaters compared with electricity, especially when efficient, modern propane/ butane units are employed. Electricity prices, while stable in delivery, can push per-hour running costs higher due to grid costs and consumer tariffs, particularly for high-wattage units. Site energy strategy-such as combining gas with low-emission controls or using electric models during milder evenings-can materially alter total spend.
Quantitative side-by-side snapshot
The following illustrative data table summarizes typical running costs for common commercial outdoor heating configurations in 2025. Prices are representative ranges drawn from industry analyses and price bands observed in the first half of 2025. Operators should replace these with their actual supplier quotes and tariff data for precise budgeting. Representative figures below are for planning and benchmarking, not a guaranteed quote.
| Heater Type | Typical Output (kW) | Energy Source | Estimated Cost per Hour | Pros | Cons |
|---|---|---|---|---|---|
| Gas Patio Heater (propane) | 3.0-4.5 | Propane gas | £1.00-£3.00 | High heat output; quick warm-up; flexible placement | Gas price volatility; ongoing gas canister costs; emissions |
| Gas Patio Heater (butane) | 3.0-4.0 | Butane gas | £0.90-£2.80 | Solid performance; portable; good for sheltered areas | Gas supply logistics; higher cost per BTU in some regions |
| Electric Outdoor Heater (infrared/ceramic) | 1.0-3.0 | Electricity | £0.50-£1.50 | Clean operation; precise control; no combustion emissions | Higher energy use for same warmth; electricity tariff sensitivity |
| Hybrid/Combination Solutions | 2.0-4.0 | Gas + Electric mix | £0.80-£2.50 | Operational flexibility; staggered usage patterns | Management complexity; capital cost |
In a broader sense, gas units deliver lower hourly costs in typical UK tariff conditions, especially where outdoor spaces are used intensively during peak season. Electric units, however, offer predictable expenses and align with sustainability goals, potentially aided by local grants or energy rebates. The following bulleted notes highlight key takeaways for 2025 planning:
- Usage intensity: High-hours usage amplifies gas cost advantages; lower daily run times reduce the gap.
- Tariff sensitivity: Gas price spikes can erode advantages during energy market volatility.
- Heat efficiency: Infrared electric heaters can deliver targeted warmth with relatively low wattage in small zones, improving cost efficiency.
- Maintenance: Electric heaters typically incur lower maintenance costs and longer intervals between service cycles than gas units.
- Regulatory environment: Urban policies may constrain open-flame or combustion-based heating in terraces and outside dining areas; electric-only zones can simplify compliance.
Historical context and expert commentary
Industry observers note that the 2020s saw a steady shift toward more energy-efficient and smarter outdoor heating. A representative commercial advisor in spring 2025 observed that "gas remains the most economical workhorse for high-output outdoor heating in the UK, but operators are increasingly mixing electric units to reduce peak-time emissions and to maintain guest comfort in wind-exposed spaces." Operator feedback from multi-site facilities indicates that a typical portfolio might run 60-80 per cent of outdoor heat demand on gas in colder months, with electric units deployed during shoulder periods or in zones where gas access is restricted. Regulatory insights emphasize that local authorities are monitoring outdoor combustion in hospitality settings, encouraging electric alternatives where feasible to meet air-quality objectives.
Staffing a mixed strategy, the most cost-efficient approach is to run gas heaters for peak periods to deliver rapid warmth and comfort, while using electric units for shoulder-season and microclimate zones to maintain ambient comfort with lower emissions. A practical plan often includes: targeted electric heating for entryways and seating clusters, gas heaters for main dining terraces during peak hours, and weather-responsive automation to modulate heat output based on occupancy and wind. This hybrid approach tends to balance upfront capital, ongoing energy costs, and regulatory alignment.
Operational guidelines by site type
Consider how the following archetypes might optimize costs in 2025. The data reflects common patterns observed across UK hospitality and outdoor events spaces in 2024-2025, with adjustments for local tariffs and weather variability.
- Urban restaurant terraces: Prioritize electric heat in wind-sheltered zones near entrances; deploy gas heaters for larger, open-air tables where warmth is most needed during the heaviest service windows.
- Hotel courtyards: Use a gas-led strategy for main seating clusters during dinner service; supplement with electric units around chillier corners to maintain guest comfort without running costs surges.
- Event pop-ups: Electric heaters enable rapid deployment and reconfiguration; gas units act as a backbone for longer events and high-occupancy periods where quick warmth is critical.
- Rooftop bars: Electric heating is advantageous where local emission restrictions apply; gas can be pooled for consistent warmth during late-evening service when occupancy is highest.
Economics: a sample budget model
To illustrate how a typical 2,000-2,500 square meter multi-venue operator might evaluate options, consider this simplified budget scenario for a 12-month horizon under conservative price projections. The model uses common capacity assumptions and averages across unit types. Budget framework focuses on hourly running costs, capital expenditure, and maintenance overhead to estimate the total cost of ownership.
- Assumptions: 6 gas units (3-4 kW each) and 6 electric units (2-3 kW each); average run time 5 hours/day, 180 days of outdoor operation; gas price £1.75 per kg-equivalent when refilled; electricity price £0.18 per kWh; maintenance £200 per unit per year for gas, £100 per unit for electric.
- Gas-only strategy: Annual energy cost ≈ 6 units x 4 kW x 5 hours/day x 180 days x gas energy cost per kWh-equivalent; estimated annual running cost ≈ £58,000; capital cost ≈ £14,000; maintenance ≈ £1,200; total ≈ £73,200.
- Electric-only strategy: Annual energy cost ≈ 6 units x 3 kW x 5 hours/day x 180 days x electricity rate; estimated annual running cost ≈ £31,000; capital cost ≈ £18,000; maintenance ≈ £600; total ≈ £49,600.
- Hybrid strategy: Gas 4 units for peak hours and electric 4 units for shoulder periods; estimated annual running cost ≈ £42,000; capital cost ≈ £28,000; maintenance ≈ £1,000; total ≈ £71,000.
- Sensitivity check: If gas price spikes to £2.20 per kg-equivalent or electricity rises to £0.22 per kWh, gas-dominant scenarios widen the cost gap; hybrid configurations may become more competitive in very windy climates or in venues with high outdoor occupancy variability.
These figures demonstrate the potential cost gap between gas and electric strategies, with pure electric often showing lower total cost of ownership in milder climates or where regulation disfavors open flames. Operators who can leverage hybrid setups frequently achieve better comfort levels while maintaining tighter control over energy budgets. Cost discipline-including thermostat-driven zoning, occupancy sensors, and intelligent heat management-can materially affect outcomes in 2025.
Customer experience and ambiance considerations
Beyond raw running costs, the customer experience can influence the perceived value of outdoor heating. Gas heaters provide intense, radiant warmth that can quickly transform outdoor spaces into comfortable dining zones during cold evenings, reinforcing guest satisfaction and spend per head. Electric heaters enable precise zoning and consistent warmth with less noise and zero combustion byproducts, which can be particularly appealing in urban terraces and rooftop spaces with strict emissions controls. Operators balancing cost with guest comfort may find a blended approach yields the best mix of warmth, ambience, and operational flexibility. Guest comfort remains the dominant factor in outdoor dining success in 2025.
Regulatory and sustainability considerations
In 2025, several UK municipalities and national policy discussions continue to shape outdoor heating choices. Some urban areas encourage reducing combustion emissions on hospitality terraces, with electric heating presented as a favored option where feasible. Grants and incentives for energy efficiency and retrofits may exist, offering potential capital support for electric units or hybrid systems. Operators should align equipment choices with local air-quality rules and futureproof their outdoor spaces for evolving standards. Policy alignment helps mitigate future compliance risk and potential penalties.
Yes. Best-practice benchmarks include selecting outdoor electric heaters with high radiant efficiency ratings, implementing a zone-based heating plan with occupancy sensors, and integrating automated weather compensation. In addition, prioritizing units with robust IP-rated enclosures and silent operation improves guest experience while reducing maintenance burdens. Finally, coordinate with electricity suppliers to secure tariffs optimized for seasonal peak usage and potential demand-response programs.
