Fit a blind to a roof window

Fit a blackout or pleated blind to a roof window safely, using the correct brackets for your exact window model.

RB-01Match the blind to your window modelRoof window blinds are made to fit one specific brand and size, not a generic gap. Check the model code on a sticker inside the window frame (common on Velux, Fakro and Roto windows) and compare it to the blind packaging before you start. Fitting the wrong kit means the brackets simply won't line up.

RB-02Set up safe access to the windowRoof windows are usually set into a sloped ceiling, so you'll be working above head height. Use a proper step ladder on flat, solid ground, never a chair or the windowsill itself, and keep three points of contact as you reach up. If the window is over a stairwell or landing, get someone to steady the ladder or hold the parts for you.

RB-03Unpack and lay out the partsOpen the kit on a flat surface and check you have the top bracket, bottom bracket or guide rails, the blind unit itself, and a small bag of screws. Read the instruction sheet once fully before touching a screwdriver, since bracket order varies between models. This fixing goes into the window frame itself, not the surrounding wall or ceiling, so you don't need a stud detector or cable detector for this job.

RB-04Fit the top bracketMost roof window blinds clip straight onto a pivot bar already fitted at the top of the window, no drilling needed. If your kit is screw-fixed, the frame usually has small pre-marked dimples showing exactly where to drill; use a 2mm bit and only go as deep as the screw length, since drilling further can hit the glazing seal. Wear eye protection, as you'll be working above your head.

RB-05Fit the bottom bracket or guide railsRepeat the same process at the bottom of the window, using the marked points or clip-on fixings supplied. Check the bracket sits square using a small spirit level before tightening any screws fully. If your blind uses side guide rails instead of cords, fit these down each side now, keeping them parallel.

RB-06Attach the blind unit to the bracketsOffer the blind up and clip or slot it into the top bracket first, then swing the bottom into place. Most designs click firmly home, you shouldn't need to force anything. If it doesn't seat properly, check the top and bottom brackets are aligned and at the correct spacing for the blind length.

RB-07Fit and tension the side cordsIf your blind uses cords rather than rigid guide rails, thread these through the small eyelets or hooks on each side of the frame. Pull each cord until it's taut but not overly tight, since it needs to run smoothly without slack or excessive strain.

RB-08Test the blind fullyRaise and lower the blind several times, checking it runs smoothly without catching or sticking on one side. If it snags, loosen the affected bracket screw slightly, nudge it square, and retighten. Check the blind sits flat against the glass when fully closed.

RB-09Tidy upFold down the ladder and put it away safely. Gather packaging and offcuts for recycling, and wipe down the window and frame with a dry cloth to remove any dust or fingerprints from fitting.
