Buying Guide
Heat type — gas, electric or infrared
Decide whether you want LPG/propane gas, electric or infrared heaters. Gas freestanding 'mushroom' heaters give strong, immediate warmth and are portable, while electric/infarared panels are neater for balconies, have lower running noise and are often legal where open-flame devices are restricted.
Power and coverage
Check the output (kW or BTU) to understand how much area a heater will warm — under-£300 models typically range from 1.5–11kW depending on type. Match the heater to your space: a 1.5–2kW electric panel suits a small balcony, whereas a 7–11kW gas heater is better for larger patios or groups.
Size, mounting and portability
Think about where you’ll place the heater: freestanding mushroom heaters are portable but need floor space, wall- or ceiling-mounted electric/infarared models save space and suit flats. Also check whether the unit folds or has wheels if you plan to store or move it regularly.
Safety and controls
Look for safety features such as tip-over cut-outs, flame failure devices and secure regulator attachments for gas heaters, plus IP-rated weather protection for outdoor electrics. Easy-to-use controls (multiple heat settings, remote control or timer) make temperature management simpler and safer.
Build quality and running costs
Stainless-steel or powder-coated steel bodies last longer outdoors and resist rust; check warranty terms. Consider running costs — electricity is predictable and convenient, while LPG can be cheaper per hour for high-power units but requires cylinder storage and replacement.
Frequently Asked Questions
What is the best patio heater in 2026?
There’s no single 'best' heater for everyone — the top choice depends on use. For large outdoor gatherings a freestanding 7–11kW gas mushroom from reputable brands offers the most immediate warmth under £300, while for balconies or terraces a 1.5–2kW infrared wall panel gives efficient, targeted heat.
Is a patio heater worth buying in the UK?
Yes, if you regularly use your garden, patio or balcony in cooler months a patio heater can extend usable time outdoors. Consider running costs, local rules for flats and available space before buying to ensure it’s cost-effective.
Which patio heater offers the best value for money?
Value depends on how you use it: an electric infrared panel can be the best value for small, frequent use due to low maintenance, while a mid-range gas heater often gives better heat-per-pound for larger, occasional gatherings. Buy from established retailers (Argos, B&Q, Screwfix, Amazon UK) and compare warranties.
Electric vs gas patio heaters - which should I buy?
Choose electric if you need a compact, low-maintenance option for balconies or if open flames are restricted; choose gas for higher output and quicker heating of open spaces. Also weigh running costs and cylinder storage for gas against electricity tariffs.
VonHaus vs Outsunny - which should I buy?
Both brands sell budget-friendly under-£300 models: VonHaus often focuses on build quality and user-friendly features, while Outsunny provides a wide model range and competitive pricing. Compare the exact model specs — power (kW), materials (stainless steel vs painted steel), safety features and customer reviews — to pick the better fit.
Can I use a patio heater on a balcony or in a flat in the UK?
You can use some electric and low-profile infrared heaters on balconies, but freestanding gas heaters may be restricted by building rules, lease agreements or local fire safety regs. Always check your building management, landlord terms and local bylaws before installing a gas or open-flame heater.
Where can I buy reliable under-£300 patio heaters in the UK?
Major retailers such as Argos, B&Q, Screwfix, Wickes and Amazon UK stock affordable patio heaters, plus seasonal deals at Lidl or Aldi. Buy from sellers with clear return policies and check warranty and spare-part availability.
How much does it cost to run a patio heater?
Running costs vary: an electric 1.5–2kW infrared panel uses roughly £0.40–£1 per hour depending on your electricity tariff, while a gas heater running at 7–11kW burns LPG which can be cheaper per hour but requires cylinder replacement. Estimate costs based on kW output and your local energy prices to compare accurately.
