Radiator Cover Measurement Guide

Welcome to our Radiator Cover Measurement Guide. Please read all instructions carefully before placing your order to ensure a perfect fit.


📏 Standard Radiator Covers
(No shelving or side storage)

To ensure your radiator has enough space to breathe and for proper ventilation, you must add at least 5cm to your radiator measurements on all sides (width, height, and depth).

  • The 5cm allowance allows airflow and ensures the cover fits over the radiator.
  • Top shelf includes a 1.5cm overhang on each side.
  • If your radiator is in an alcove, near a door frame, or under a window sill, please contact us before ordering.

All measurements are external. We use 18mm MDF, which is already included within the 5cm allowance. Do NOT add extra for MDF thickness.

When selecting your size from the options, please ensure you have already added the ventilation allowance to your radiator measurements.


🪵 Skirting Board Cut-Out

Measure the height and depth of your skirting board (in CM) to allow the radiator cover to sit flush against the wall.

If you do not require a skirting board cut-out, please do not select this option.


🗄 Radiator Covers With Drawers Above

  • Add 5cm allowance to width and depth as standard.
  • Add 20cm to the radiator height to allow for drawers above.
  • The 20cm allowance already includes the 5cm ventilation gap.
  • Top shelf includes a 1.5cm overhang on each side.

📚 Radiator Covers With Bookcase or Overhead Media Shelving

  • Add 5cm allowance to width and depth.
  • The height entered should be the overall total height including the shelving or bookcase.
  • Please add your internal radiator measurements in the notes section.
  • Top shelf includes a 1.5cm overhang on each side.

🧺 Radiator Covers With Side Shelves or Side Shoe Storage

  • Add 5cm allowance to height and depth.
  • The width entered must be the total width including side storage.
  • Please include internal radiator measurements in the notes section.
  • Top shelf includes a 1.5cm overhang on each side.
