Why Choose a Patio Heater Under £100 in April 2026?

UK springs are unpredictable; April evenings average 8-12°C, dropping quickly after dark. Patio heaters extend usability by 2-3 hours, ideal for BBQs or pub-style garden gatherings. Under £100, you get models with 8-13kW power, safety certifications (CE/GS), and portability. Gas patio heaters excel in open spaces with high BTU (British Thermal Units), whilst electric ones are plug-and-play for rentals. Running costs: gas ~£1-2/hour, electric ~20-50p/hour on Economy 7 tariffs. Always check hose regulations for gas and IP ratings for rain resistance.
