Anthracite grey sliding doors across Wiltshire
A few practical points decide whether anthracite grey sliding doors suit a particular room and opening:
If your Wiltshire home is listed, is a flat, or is covered by an Article 4 direction, check with the council before changing the colour of a door that faces the street.
If the windows on your Wiltshire home are already anthracite, take a photo of the colour label on a frame or the paperwork so the door can be specified to the same RAL number.
- Powder coating is cured in an oven into a continuous film, giving a hard-wearing finish that does not need repainting, only occasional washing with mild soapy water.
- Grey sits comfortably with a wide range of materials, from buff and red brick to white render, timber cladding and stone, which keeps future redecorating options open.
- Dual colour lets you keep anthracite on the outside for kerb appeal while choosing white or a soft neutral inside, so the frame suits the room you see every day.

Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about anthracite grey sliding doors in Wiltshire
Do I need building approval for anthracite grey sliding doors in Wiltshire?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
Do anthracite grey frames fade?
Good-quality polyester powder coatings are formulated to resist UV fading, so an anthracite frame should keep its colour for many years with routine cleaning. Some gradual change in sheen is normal on very exposed, sunny or coastal elevations. Washing the frames a few times a year removes salt and grime that can dull the finish over time.
How does powder coating work?
Powder coating is a dry finishing process that bonds coloured polyester powder to the aluminium with heat. The profiles are cleaned and pretreated, the powder is sprayed on with an electrostatic charge so it clings evenly, and the frame is baked until the powder melts into a smooth, hard film. It resists chipping and fading far better than wet paint.
Is anthracite grey more expensive than white?
On our aluminium doors anthracite grey is a standard colour, so a single-colour anthracite door normally costs the same as white. A dual colour frame, or a non-standard RAL shade, adds to the price. The guide price for a 2.4 m two-panel aluminium door is £4,295–£5,295, fitted, inc VAT at standard 2.1 m height.
