Perfect Fit
Aluminium
Venetian Blinds
Clips into the window bead with no drilling, no brackets, and no damage to your frames. Clean lines, precise light control, and a finish that looks built-in.
Clips straight into your bead.
Snaps in. No screws. No mess.
A perfect fit blind uses a slim outer frame that clips directly into the internal bead of your uPVC window. There's nothing screwed into the wall or the frame — the bead grips the bracket, and the whole blind sits flush inside the glass area. Open the window normally, and the blind moves with it.
The venetian mechanism sits inside the headrail. Ladder tapes run down either side, holding each aluminium slat in a horizontal row. Rotate the tilt wand to angle the slats — anywhere from fully open to fully closed — to dial in exactly how much light comes through.
Angle the slats to filter or block light without raising the blind. Useful in rooms where you want daylight but not direct sun or street views.
We offer cord-free perfect fit venetians with a safe wand tilt only. No exposed cord loops — fully compliant with current UK child safety regulations.
Because the blind is attached to the window sash — not the wall — it stays in position when you open or tilt the window. No tangling, no catching.
What makes aluminium venetians different
Six things that set perfect fit aluminium venetians apart from other options for uPVC windows.
Each slat sits in a calibrated ladder tape, so they all tilt in unison and hold their position. There's no sagging or unevenness — the slats stay exactly where you put them.
The clip-in system needs no screws, no rawl plugs, no brackets bolted to the wall. Important if you rent, or if you simply don't want unnecessary holes in a new window frame.
Unlike fabric or wooden blinds, aluminium slats won't warp, swell, or discolour in humid conditions. They're a good practical choice for kitchens and bathrooms where condensation builds up.
A damp cloth or microfibre duster is all you need. The slats don't absorb dust or grease the way fabric does. Close them flat to wipe across all slats at once in a single pass.
Choose 16mm slats for a refined, high-frequency look, or 25mm for a broader, more contemporary style. Both work within the same slim perfect fit frame, so the look from outside is identical.
The outer frame matches standard uPVC window colours — white, cream, grey, or anthracite — so the blind sits flush with the profile and looks like part of the window rather than something hung in front of it.
16mm or 25mm — which is right for you?
Both sizes work within the same perfect fit frame and give the same level of light control. The difference is purely visual — it comes down to the scale of your window and the look you want.
More slats visible across the same window area, giving a finer, more detailed look. Works especially well on smaller windows — casements, fanlights, and door sidelights — where wide slats would look heavy.

Fewer, broader slats give a bolder, more modern look. A popular choice on standard casements and larger panes. The wider slat is easier to wipe clean and feels more substantial when you tilt it.

Slat colours to suit your space
Aluminium slats come in a range of lacquered and metallic finishes. All are hardwearing and easy to wipe clean.
A brushed mid-silver finish that sits neutrally against most uPVC window colours. Works well in modern kitchens and home offices.
A clean white with a subtle sheen that blends with white uPVC frames. A straightforward choice if you want the blind to disappear into the window.
A deep anthracite grey that adds contrast against white frames. Popular in contemporary schemes and pairs well with grey or anthracite window profiles.
A softer, warmer grey tone that bridges silver and charcoal. Sits comfortably in living rooms and bedrooms where a harder metallic might feel out of place.
The outer frame matches your window profile
We measure and match the frame colour to your window at the survey. Standard options cover almost all uPVC profiles in use across the North East and North West.
Where perfect fit aluminium venetians work best
Rooms and window types where the combination of clip-in fitting, tilt control, and wipe-clean aluminium slats really earns its place.
Aluminium won't absorb cooking smells or steam, and it's quick to wipe down. The tilt control is useful over a sink where you want light from above but privacy from outside.
Unlike fabric or wood, aluminium slats won't warp or discolour in a steamy bathroom. The perfect fit frame seals neatly into the window bead, reducing gap around the blind.
Tilt the slats to cut glare from a screen without losing all the daylight. Because there's no pelmet or track above the window, you keep a clean visual line that doesn't distract.
Most conservatory windows have the internal uPVC bead that perfect fit needs. Aluminium slats hold up better than fabric in the fluctuating temperatures of a conservatory.
No drilling means no damage to the frames — nothing that a landlord or letting agent could raise at the end of a tenancy. Clips off cleanly when you move out.
The 16mm slat option is particularly suited to narrow sidelights beside front or back doors where a wide slat would look out of proportion. Keeps the view managed without blocking light entirely.
Other blinds in the perfect fit range
Wipe-clean aluminium slats with tilt control. 16mm or 25mm. Best for kitchens, bathrooms, and offices.
Real wood slats with a warmer, more natural look. Suited to living rooms and bedrooms in dry conditions.
Fabric pleats in a slim clip-in frame. Good for softening a window without the structure of a venetian.
Clean fabric roll in a clip-in frame. Available in blackout, filtering, and thermal options.
What customers say
"Had these fitted in the kitchen and bathroom on the same day. The surveyor was spot on with the measurements — they clipped in cleanly and the 25mm slats look much more modern than the old fabric ones we had. Really easy to wipe down around the cooker."
"I was worried about my tilt-and-turn windows — the surveyor said they were perfect for these. The blind sits flush with the frame and opens with the window exactly as described. I've had blinds fall off standard brackets before, so this was a revelation."
"Renting, so couldn't drill anything. These were recommended and I'm glad I went for them. The charcoal 16mm slats on the door sidelights look really sharp. Landlord hasn't said a word — you'd never know they weren't fitted with the windows."
Common questions about perfect fit aluminium venetians
Can't find what you're looking for? Call us or book a free survey — we'll answer any question at the visit.
Will perfect fit blinds work on my windows?
They work on internally-beaded uPVC and composite windows — which covers most double-glazed windows fitted since the mid-1990s. The blind clips into the plastic bead on the inside edge of the frame. They won't work on traditional timber windows because those don't have the same bead profile. We check the compatibility of every window at the free survey before anything is ordered.
Can I open the window with the blind fitted?
Yes — that's one of the main reasons people choose them. The blind attaches to the sash or opening panel, so it moves with the window when you open it. Side-hung casements, top-hung fanlights, and tilt-and-turn windows all work normally with the blind in place.
What is the difference between 16mm and 25mm slats?
Both sizes give the same light control and sit in the same perfect fit frame. The difference is visual: 16mm slats are narrower, so you see more of them across the window — a finer, denser look. 25mm slats are broader, giving a bolder, more contemporary appearance. We bring samples to every survey so you can see both in your actual window before choosing.
Are they child-safe?
We offer cord-free versions of our perfect fit aluminium venetians, controlled by a tilt wand only. These have no exposed cord loops and are fully compliant with current UK child safety regulations. We recommend the cord-free option as standard for homes with young children.
How do I clean aluminium venetian slats?
Close the slats flat and wipe across them with a damp microfibre cloth or a soft duster. Because aluminium doesn't absorb grease or moisture, a quick wipe is usually all that's needed. For a thorough clean, you can remove the blind from its clip-in frame, take it outside, and rinse it down — it clips straight back in when dry.
Are aluminium venetians suitable for bathrooms?
Yes — they're one of the better choices for bathrooms. Aluminium slats don't warp, swell, or discolour in humid conditions the way timber or some fabrics do. Just avoid soaking the headrail or bottom rail directly, and wipe them down rather than rinsing in place.
How much do perfect fit aluminium venetians cost?
Price depends on the size of each window, the slat width you choose, and the number of blinds. We quote a fixed price at the free home survey — that's the price you pay on the day of fitting with no hidden extras. There's no obligation to go ahead after the survey.
Do you supply and fit, or just supply?
We measure, make, and fit everything ourselves — there's no third-party installer. The same team that surveys your windows fits the blinds, so any adjustments can be handled on the spot. We cover the North East and North West of England.
