FLAMME Knighton Platinum Review UK 2026
Quick verdict
Score: 7.8/10
Best for: A built-in focal point in a media wall or chimney breast
Not for: Heating a large or poorly insulated room - electric fires are supplementary heat
Bottom line: A practical electric fireplace (inset / media wall fire, 71in wide) for a cosy focal point.
The FLAMME Knighton Platinum is a 71-inch (180cm) slim-frame media wall inset electric fireplace designed for inset installations in a media wall. This flamme knighton platinum review UK focuses on fitment, as the 71-inch inset format suits wide media panels, and the model is positioned as an electric fire option with app and smart control. The product title does not state viewing-side layout, power details, or fuel-bed specifics beyond "deep", so it is only a strong match if those missing details align with the requirements.

Style and Installation
Style and installation are driven by the fact that this electric fireplace is an inset media-wall electric fireplace designed to sit flush in a built-in opening, so the wall design and cut-out size planning matter from the start. The unit is 71 in (180 cm) wide, so framing needs to match that width and allow for safe installation space around the aperture. This is a slim-frame media wall inset fire that suits modern wall builds. As it is 1-2-3 sided view compatible, positioning should be planned around the intended sightlines to ensure the edges are concealed cleanly. Smart control is supported, so wiring routes should be mapped early in the installation.
Heat Output and Room Size
With the FLAMME, the unit is 71 in wide (about 180 cm), which gives broad coverage across the wall, but the room comfort level still depends on how much energy is delivered. In a smaller or better-insulated room, the heat may feel more noticeable at moderate settings, while a larger or less well-insulated space may require higher output. For best results, the installer should consider the room dimensions first and then check comfort after installation.
Flame Effect and Realism
The Flame Effect on the Flame Effect and Realism-focused Flame/Fire media wall setup is built around visual layering rather than a physical fuel effect. With a deeper fuel bed look, the design aims to reduce the flat appearance often associated with inset electric displays, helping the flames read more naturally across the front of the installation. The 71-inch (180cm) width also suits a wider viewing view across a media wall, provided the flames remain clearly visible in the room's line of sight. Realism is still influenced by viewing angle and ambient light, since brighter conditions can lower perceived contrast. With no stated flame animation specifications available, performance is best described as a visual effect design, not a measured flame system.
Controls and Features
Beyond the visual flame layering, the electric fireplace's day-to-day usability centres on its smart control options, described as app and smart control in the product information, with Alexa compatibility also listed. These controls let the fireplace be adjusted from a phone and used through smart-home routines, which can fit naturally with everyday schedules. In practical setup, the app would typically be configured first, followed by Alexa linkage to enable voice commands, provided the home network supports it. The unit is described as a 71in inset media wall unit, so control access and placement need to suit an inset media-wall installation.
Who Is This For?
The FLAMME is a strong match for people planning an inset media wall electric fireplace, particularly if a 71 in (180 cm) wide opening is available, as it is described as a slim-frame inset media wall unit for that type of installation. It suits buyers who want a 1-2-3 sided view display for more flexible layout options, and those looking for smart control features, including Alexa compatibility. It is less suitable if the installation requires a different inset width, or if a media wall setup is not being used, because the inset fitting style is central.
Where to Buy in the UK
Homeowners in the UK shopping for the electric fireplace (180cm) Knighton Platinum smart inset media wall electric fireplace typically begin with major UK retailers, checking their online product listings for the correct 71-inch (180cm) inset or media wall fit and any stated support for 1-2-3 sided view use. They compare product-page details to confirm the inset opening requirements for a 71-inch (180cm) installation, then review smart-control information to ensure the control options listed are included, since missing controls can reduce everyday convenience. Delivery terms and returns policies matter at this stage, because a mismatch between the stated opening or fit guidance and the available recess can prevent a straightforward installation. Some retailers may carry closely related models, but substitution risk increases if dimensional fit or sided-view support differs.
Frequently Asked Questions
Is the FLAMME Knighton Platinum worth it?
As a focal point built into a media wall or chimney breast, the FLAMME (inset / media wall fire) does the job. Electric fires are chosen mainly for the look and the instant, flue-free warmth. Check the current Amazon UK price, as fireplaces are discounted heavily outside the autumn peak.
How is the electric fireplace installed?
The FLAMME is an inset / media wall fire, designed to be recessed into a stud wall, media wall or chimney breast. You'll need a correctly sized recess (check the required depth as well as the width and height) and a nearby socket or a spur fitted by a qualified electrician. Plan the opening before you build the wall - retrofitting a recess is far harder.
What size is the electric fireplace?
This electric fireplace measures 71in wide. For inset and media wall fires, the width is the headline figure but the required recess DEPTH is what most often catches people out - always check it against your wall build-up before ordering. For freestanding and wall-mounted models, check the width suits the wall or alcove you have in mind.
What features does the FLAMME have?
The FLAMME Knighton Platinum offers app / smart control. Match the features to how you'll actually use it.
Are electric fireplaces expensive to run?
Running cost depends on the heat setting and your electricity tariff. At full output most electric fires draw around 2kW, so an hour at full heat costs roughly the same as running any 2kW heater - use the lower setting or a thermostat to cut that considerably. Crucially, the flame effect alone uses very little (it's just LEDs), so leaving the flames on without heat costs pennies.
