The Best Inset Electric Fires (UK 2026)

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

An inset electric fire sits flush within the wall or chimney breast for a clean, built-in look. Here's what to look for, the sizing traps, and our top inset fire picks.

Quick answer

Inset fires are recessed into an opening - either an existing chimney breast or a purpose-built stud wall. KAMINIO, Dimplex, M.C.Haus and FLAMME cover the range from compact 23-inch units to wide media wall models. The essential step is checking the required recess dimensions, particularly the depth, against the opening you have or plan to build. Get that right and fitting is straightforward.

What to look for

Measure your existing opening, or design your new one, around the fire's stated recess requirements - width, height and depth. Check whether the trim is flush-fitting or has a visible frame, as that changes the finished look considerably. Slim-depth models suit shallow stud walls. Confirm the electrical supply: a socket or fused spur positioned within the recess or nearby, fitted by a qualified electrician if new wiring is needed.

How we pick

We rate inset fires on flame realism, fitting requirements and frame finish, controls and value. Every pick is a genuine inset or recessed electric fire.

Frequently asked questions

What size inset electric fire do I need?

Measure your opening first, then find a fire whose stated recess requirements fit within it - checking depth as carefully as width and height, since depth is the dimension most often overlooked. If you're building a new stud or media wall, do the opposite: choose the fire first and build the opening to its specification. Never assume a standard size, as recess requirements vary widely between models.

Can you fit an inset electric fire in an existing fireplace?

Often yes, provided the opening is large enough in all three dimensions and you can get power to it. Existing chimney breast openings are a natural home for an inset fire, though older fireplaces may need the opening squaring up or lining. Measure the actual usable recess carefully, and have a qualified electrician provide a socket or fused spur if there isn't one.
