Propane vs natural gas – which is right for you?
Most UK gas BBQs run on propane, supplied in portable cylinders. Propane heats quickly, is widely available and works well in cooler weather. It’s ideal if you want flexibility to move the BBQ around the garden or store it in a shed over winter.
Natural gas BBQs connect directly to your home gas supply. The big advantages are convenience and running cost – you never run out mid‑cook, and per‑kWh costs are usually lower than bottled gas. The downside is that the BBQ becomes a fixed installation and you’ll need a qualified engineer to install the gas line.
In short: choose propane for flexibility and rental properties; choose natural gas if you own your home, have a permanent patio setup and grill frequently.
Heat distribution and burner design explained
Good heat distribution is what separates a frustrating BBQ from one you love using. Modern gas BBQs use a combination of burner layout, heat diffusers (sometimes called flavourizer bars or flame tamers) and lid design to spread heat evenly.
Look for:
- Even burner spacing: reduces hot and cold spots across the grill.
- Quality diffusers: metal plates or bars above the burners that vaporise drippings and spread heat.
- Heavy lids and grates: better heat retention and more stable temperatures.
- Infrared zones: on models like the Napoleon Rogue XT 625, these create intense radiant heat for searing.
For most UK buyers, a well‑designed 4‑burner with decent diffusers will feel like a huge upgrade over a basic budget grill.
How to choose the best gas BBQ for your garden
- Measure your space: check patio size, clearance from fences and access routes before committing to a 6‑burner monster.
- Decide burner count: 4‑burners suit most families; 6‑burners are great for frequent entertaining.
- Pick your fuel: propane for flexibility, natural gas for heavy use and convenience.
- Check build quality: stainless steel, solid lids and sturdy wheels are worth paying for.
- Think about extras: side burners, storage, rotisserie compatibility and warming racks all add day‑to‑day usability.

FAQs – best gas BBQs UK
Are 4‑burner gas BBQs enough for a family?
Yes. A good 4‑burner gas BBQ like the Weber Genesis E‑435 or Char‑Broil Performance 440S is more than enough for most families. You can comfortably cook for 4–6 people and still have room for indirect heat zones.
Do I really need a 6‑burner gas BBQ?
A 6‑burner model such as the CosmoGrill Deluxe or Napoleon Rogue XT 625 makes sense if you regularly host larger gatherings or want multiple cooking zones. If you only grill occasionally for a small household, a 4‑burner is usually sufficient.
Is natural gas better than propane for BBQs?
Neither is strictly “better” – it depends on your situation. Natural gas is cheaper per cook and never runs out, but requires a fixed installation. Propane is portable and easier to set up, which suits most UK gardens and renters.
How long should a good gas BBQ last?
With basic maintenance and a cover, a quality gas BBQ from brands like Weber or Napoleon can last 10 years or more. Budget models may need parts replacing sooner, but regular cleaning and protection from the weather make a big difference.
Can gas BBQs give the same flavour as charcoal?
Gas BBQs won’t fully replicate charcoal flavour, but good heat diffusers and the use of smoker boxes or wood chips can get you surprisingly close. For many people, the trade‑off in convenience is worth it.
