Black Downpipe
Black downpipe suits a dark roofline, a cast iron effect scheme or modern render where white would stand out. Plastic downpipe comes in 68mm round and 66mm square at 2.5m, 4m and 5.5m, with bends, shoes, branches and clips in the same finish. If you want something less heavy against pale render, a white downpipe might be a better fit.

Frequently Asked Questions
Match the rest of the roofline rather than the wall. White suits white fascia and guttering on most housing, black disappears against a dark roofline or a cast iron effect scheme, and grey sits well with anthracite windows and modern render. Fittings and clips are stocked in the same finishes, so a run stays consistent.
68mm round is the standard partner for half round and deep flow guttering, and 66mm square goes with square and ogee profiles. Cast iron effect systems use a narrower 65mm square to keep the period proportions. The pipe has to match the outlet on the gutter, so settle the gutter profile first.
Fix a clip within 150mm of every socket joint, then at roughly 1.8m to 2m centres down the run, with an extra clip either side of an offset bend. On a narrow passage or boundary wall, flush-fitting clips let the pipe sit tight against the brickwork.
They do not have to, but a roofline reads as one line from the ground, so mismatched whites or a grey gutter on a white fascia tend to show. If you are replacing in stages, settle the colour across fascia, soffit, guttering and downpipe at the start rather than matching to what is already up.
