Are bioethanol fireplaces safe indoors?

Yes, when used correctly. A bioethanol fireplace burns clean (CO2 and water vapour), needs no chimney, and does not require planning permission. Follow the manufacturer's guidance on ventilation and never refuel while the burner is lit or hot.

Do bioethanol fireplaces need a chimney or planning permission?

No. Bioethanol fires are flueless and, unlike gas or wood fires, do not require a chimney, flue or building-regulations approval.

Are Bioethanol Fireplaces Safe? UK Safety & Regulations Guide

Q: Do I need ventilation for a bioethanol fireplace?

Yes. Because burning produces CO2, use the fire in a well-ventilated room (many manufacturers recommend a minimum of about 20 m²) and avoid small sealed spaces.

Yes — a bioethanol fireplace is safe when used correctly. It is a real flame, so it deserves respect, but with a little common sense and a well-made, certified unit there is nothing to worry about. Here is what UK owners need to know.

Do they need a chimney or planning permission?

No. This is the main reason people choose bioethanol. Unlike gas fires and wood burners, a bioethanol fire is flueless — it needs no chimney, no flue, no gas supply and no building-regulations approval. It burns a clean liquid fuel and releases only carbon dioxide and water vapour, so there is no smoke to extract.

What standard should a safe fireplace meet?

Look for units certified to the European safety standard for bioethanol fireplaces, EN 16647, with CE marking. A certified unit has been tested for stable, leak-free construction, correct burner design and spill protection. All of our fireplaces are CE-certified, powder-coated steel construction with safe, leak-free burners.

Ventilation and room size

Because combustion produces CO₂, the fire should be used in a well-ventilated room. Many manufacturers recommend a minimum room size of around 20 m², and it is sensible to avoid very small, sealed spaces. A normal living room with a trickle vent or an occasionally opened window is ideal. Open-plan spaces are perfect.

Think of a bioethanol fire like a candle, scaled up: it is perfectly safe in a normal room, but not something to burn for hours inside a closed cupboard-sized space.

Safe use — the golden rules

Only use genuine bioethanol fuel (95–96.6% purity). Never use petrol, white spirit or any other flammable liquid.
Never refuel while the burner is lit or still hot. Wait for it to cool fully before topping up.
Keep a safe distance from curtains, sofas and other flammable materials.
Keep out of reach of children and pets while alight.
Use the included snuffer/extinguisher to put the flame out — never blow it out.
Follow the supplied manual for lighting, refuelling and maintenance.

One rule that matters above all: fuel is the one thing to handle carefully. Store bioethanol upright, out of sunlight and away from ignition sources — and never fill the burner beyond its marked level.

Indoors vs outdoors

Bioethanol fireplaces are designed for indoor use in living rooms, kitchens and open-plan spaces, and many models are also ideal for covered terraces and gardens. Always check the model's rating — indoor-rated units should not be left exposed to rain.

The bottom line

Handled properly, a bioethanol fireplace is a safe, clean and low-commitment way to enjoy a real fire with no chimney. Choose a CE-certified unit, use proper fuel, give it some ventilation, and you can relax and enjoy it for years.
