Electric Fireplace Buying Guide (UK 2026)

By the Flicker Glow editorial team · Updated 2026 · How we test & score

Choosing an electric fireplace comes down to the type and how it's fitted, the heat you actually need, the flame effect, and getting the sizing right. This guide walks through each so you can pick the right fire for your room.

Types and fitting

There are five main types. Inset and media wall fires recess into a chimney breast or purpose-built stud wall for a flush, built-in look, and need the most planning. Wall-mounted fires hang on a bracket - no recess, but check the wall type. Electric stoves stand on the floor and simply plug in. Suites combine a fire and surround for rooms with no chimney. Fireplace TV stands build the fire into a media unit. Pick the type by how much building work you're willing to do.

Heat output and room size

Almost all domestic electric fires offer 1kW and 2kW settings. At 2kW you get roughly the same heat as any 2kW electric heater - enough to warm a small to medium, reasonably insulated room, but not a large open-plan space or a whole house. Treat it as supplementary heating. A thermostat is the most valuable feature for running cost, cycling the fire off once the room is warm instead of drawing full power continuously.

Flame effect

This is what you'll actually look at, and it varies enormously. Basic LED strips glow flatly behind a panel and look artificial up close. 3D effects layer flames within the fuel bed to give depth. Dimplex's Optimyst water-vapour system produces genuine three-dimensional mist and is the most convincing available, at the cost of refilling a tank. Warm amber tones look more natural than coloured settings. Always watch video of a model running rather than relying on photographs.

Sizing, electrics and safety

For inset fires, check the required recess WIDTH, HEIGHT and especially DEPTH before building or buying - depth is the dimension most often missed. For wall-mounted fires, check the weight against your wall type and use proper fixings on plasterboard. All types need a socket or fused spur within reach; new wiring should be done by a qualified electrician. Never cover a fire, keep it clear of curtains and furniture, and plug a 2kW fire directly into a wall socket rather than an extension lead.

Frequently asked questions

How do I choose an electric fireplace?

Start with the type and how much fitting you want: inset or media wall for a built-in look, wall-mounted for minimal work, a stove or freestanding fire for none at all, or a suite if you have no chimney. Then check the heat output suits the room as supplementary warmth, assess the flame effect on video, and confirm the sizing - especially recess depth for inset models - plus a socket within reach.

Do electric fireplaces need ventilation?

No - electric fires burn nothing, so there are no combustion gases and no flue, chimney or room ventilation is required. That's why they can go in any room, including flats. They do need clearance around the heat outlet so it isn't blocked, and inset models must not be boxed in tighter than the manufacturer specifies, but that's about heat dispersal rather than ventilation for fumes.
