Flat plates (sometimes called slimline plates) sit almost flush against the wall, giving a more minimal look than standard raised plates — but they need a little extra checking before you order.
What's the Difference Between Flat and Standard Plates?
Standard plates have a visible depth or “step” between the plate and the wall. Flat plates are designed to sit close to the wall surface for a cleaner, more contemporary appearance.
Why Does Wall Depth Matter With Flat Plates?
Because flat plates sit closer to the wall, there's less room behind them for wiring and the back box than with a standard plate. Older or shallower back boxes may not leave enough room for the cabling once a flat plate is fitted.
What Should I Check Before Ordering?
The depth of your existing back boxes
Whether the flat plate range is designed to fit standard UK back boxes, or requires a specific box
How much cable and how many conductors need to fit behind the plate
Our Advice
If you're renovating and fitting new back boxes, flat plates are straightforward to plan for. If you're replacing existing plates on old back boxes, it's worth checking the depth first, or asking your electrician to confirm compatibility before you order.
