Buying Guide
Type and fuel
Decide between electric (infrared/panel/halogen) and gas (LPG) heaters — electric models are usually cleaner, quieter and easier to install, while gas units deliver higher output for open spaces. For a budget under £300 you’ll most commonly find electric freestanding or wall‑mounted infrared heaters that are suitable for balconies and small patios.
Heat output and coverage
Check the rated power (kW) and the manufacturer’s suggested coverage area — a 1.5–2kW electric infrared heater is typically enough for a small seating area, while larger spaces need higher output or multiple units. Keep in mind that infrared heaters are directional, so positioning matters more than raw kW.
Installation and portability
Decide whether you want freestanding, wheeled, wall or ceiling‑mounted units; fixed wall or ceiling models save space and are tidier, whereas freestanding heaters are portable and need no installation. If you live in a flat, check balcony rules and whether drilling is permitted before choosing a fixed mount.
Running costs and fuel availability
Factor in ongoing costs: electric infrared heaters have predictable running costs per kWh and no refills, while gas heaters need LPG cylinders that can be more expensive but give stronger warmth outdoors. Compare typical power ratings and your electricity tariff or the local cost of LPG to estimate hourly running costs.
Safety and weatherproofing
Look for an IP rating (IP44 or higher for outdoor use), tip‑over and overheat cut‑outs, and sturdy bases or secure mounting options. For covered patios choose appropriate splash protection; avoid leaving devices exposed to driving rain unless they’re rated for it.
Frequently Asked Questions
What is the best patio heater in 2026?
There isn’t a single best model for everyone — in 2026 the best choice under £300 will usually be an electric infrared wall or freestanding heater with around 1.5–2kW power, an IP44 rating and useful extras like a remote and timer. Look for reputable retailers (Argos, B&Q, Screwfix, Amazon UK) and favourable reviews that confirm coverage and build quality for your space.
Is a patio heater worth buying in the UK?
Yes for many people: a patio heater can extend the usable season for patios and balconies, especially during cool spring and autumn evenings. Consider the running cost, local restrictions (flat blocks may ban certain heaters) and whether a directional infrared unit or a gas heater better suits your outdoor layout.
Which patio heater offers the best value for money under £300?
Electric infrared heaters with 1.5–2kW output, an IP44 rating, adjustable tilt and a remote usually offer the best value under £300 — they’re cheap to buy, simple to install and economical to run for small areas. Avoid cheap halogen units with poor protections; check warranty length and customer reviews.
Electric vs gas patio heaters — which should I buy?
Choose electric if you want ease of use, lower running fuss and indoor‑safe options for covered terraces; pick gas if you need higher, area‑filling heat and mobility away from sockets. For a budget under £300, electric infrared is often the most practical and widely available option in the UK.
Are patio heaters legal to use on balconies or in flats?
There’s no single UK law forbidding patio heaters, but many flats and leasehold buildings have management rules that restrict or ban gas heaters or open‑flame appliances on balconies for fire safety. Always check your building regulations, lease or landlord guidance before installing or using a heater.
How much does it cost to run an electric patio heater in the UK?
Running cost depends on power and your electricity tariff; a 1.5–2kW electric heater on a typical UK electricity rate might cost roughly £0.15–£0.60 per hour (estimate varies with tariff and efficiency). Using timers, lower power settings and directing heat efficiently will reduce running costs.
Where can I buy reliable patio heaters under £300 in the UK?
Major UK retailers such as B&Q, Argos, Screwfix, Wickes and Amazon UK stock a wide range of heaters under £300. Compare specs (kW, IP rating, mounting options), warranties and customer reviews, and check return policies in case the unit doesn’t warm your space as expected.
Can I leave my patio heater outside in the rain?
Only if the heater has an appropriate outdoor IP rating (IP44 minimum for splash protection); many indoor or cheaply made models aren’t weatherproof and should not be left exposed. Even weatherproof units benefit from a cover or sheltered position to extend lifespan.
