The short version
Anthracite grey (RAL 7016) is a deep, warm charcoal. Jet black (RAL 9005) is a true, high-contrast black. Anthracite is the safer, softer choice that flatters almost any property; black is the bolder, sharper statement that shines on the right house and can overpower the wrong one.
Anthracite grey: the all-rounder
Anthracite has a hint of warmth that stops it looking cold or stark. It blends with red brick, render and stone, and it hides road dust and rain marks well. It's the colour we spray most across South Wales, and the reason it's become the default upgrade on premium new-builds. If you want a modern look you won't second-guess, choose anthracite.
Jet black: the statement
Black gives the crispest contrast against light render and pale brick, which is why it works so well on terraces and contemporary new-builds. It's striking and architectural. The caution: on a house that's already dark, or heavily shaded, black frames can disappear or feel heavy. In strong sun, a true black also shows surface dust a little more than grey.
Which suits your property?
- Red or warm brick: anthracite usually wins; it complements rather than competes.
- Cream or white render: both work; black gives maximum contrast, anthracite a softer line.
- Period property: anthracite is the more sympathetic of the two; for real heritage, consider sage or Chartwell green instead. See our guide to the best colours for UPVC windows.
- Modern new-build: either; black on a pale rendered box looks superb.
Finish matters as much as colour
We spray both in a 5% matt by default, which keeps them contemporary and low-maintenance. A matt black reads as deliberate and modern rather than glossy and dated. Whichever you pick, the finish and preparation decide how long it lasts, see how long a UPVC respray lasts.
