Aluminium Venetian Blinds London: Guide
Settled on aluminium Venetian blinds. Good choice. The next job is picking the slat width. Then the finish. Then the colour. Our aluminium Venetian blinds London customers choose a 25mm slat as standard, then pick from six finishes and 74 colours. The real question isn’t whether aluminium suits your room. It’s whether these three choices together give you the look and the light control you actually want, on the window you actually have. This guide works through each choice in turn, using only what our own aluminium Venetian blinds range offers, not general industry assumptions about what an aluminium blind can do.
Aluminium blinds slat width: why 25mm is the standard
Our aluminium Venetian blinds use a 25mm slat. That’s narrower than the 35mm and 50mm slats on our wood Venetian blinds. The difference shows up once the blind is fitted. A narrower slat stacks tighter when the blind is raised, so less glass is covered at the top of the window. It also gives a finer line across the glass. This is the look most people picture when they think of a classic Venetian blind.
One slat width keeps the decision simple. You aren’t choosing between several aluminium sizes. You’re deciding whether 25mm suits your window better than a deeper wood slat. Our wood Venetian blinds page covers the wood option in full, for anyone still weighing up material rather than width. The next section puts the two side by side.
Aluminium blinds slat width against wood: 25mm compared with 35mm and 50mm
Line the three slat sizes up and the differences are easy to see. The 25mm aluminium slat gives the smallest stack and the most delicate look. The 35mm wood slat sits in the middle: warmer, but with a slightly deeper stack. The 50mm wood slat is the boldest option, better suited to a large window where a fine 25mm slat would look lost. No single width wins in every room. It comes down to the size of your window and how much you want the slats to show. On a small window, a 25mm slat tends to look proportionate where a 50mm slat can feel heavy. On a wide or tall window, the deeper wood slats hold their own and the stack height matters less.
Damp rooms raise a different question, and it has its own answer. We’ve covered it in full, weighing up real wood against faux wood and aluminium, in our guide to which Venetian material suits a bathroom or kitchen. Read that first if a steamy room is why you’re looking at aluminium.
Made to measure aluminium Venetian blinds: why exact measurements matter
Made to measure aluminium Venetian blinds are built from your own window measurements. They aren’t cut down from a standard size. With a Venetian blind, that matters more than it might with other blind types, because the slats sit at fixed intervals along the ladder tape. Force a blind to fit a window it wasn’t made for, and the spacing can end up uneven at the top or bottom of the stack. The headrail can sit slightly proud of the recess too. A blind built from your own figures avoids both problems and sits flush against the frame.
We measure your windows on a free home visit, with no obligation to buy. The blind is then made to those exact figures. Aluminium blinds made to measure through us are typically ready and fitted within 7 to 10 working days of your order. Worth knowing if you’re working to a date, such as moving in or finishing a room by a set week.
Finishes and colours in our aluminium Venetian range
Colour is where aluminium Venetian blinds give you the most room to make a window your own. Our range runs to 74 colours: silvers, contemporary stripes and brighter shades sit alongside the more familiar black and white. Underneath that colour range are six finishes. Each one changes how the slat catches the light, not just what colour it is. The table below sets them out.
| Finish | What it looks like |
|---|---|
| Plain | A flat, even colour with no pattern on the slat |
| Brushed | A soft, linear texture that softens reflections |
| Metallic | A brighter, more reflective slat surface |
| Hammered | A dimpled, textured surface that breaks up light |
| Perforated | Tiny holes through the slat for a softer, diffused effect |
| Woodline | A printed wood grain on an aluminium slat |
Choosing a colour for your aluminium Venetian blind
With 74 colours on offer, it helps to start from what the room already has rather than scrolling through every shade. A bright white or silver slat keeps a small room feeling open. It reflects more light back into the space. A darker plain colour suits a room that already gets plenty of natural light, letting the window treatment sit back rather than stand out. Stripe options land in between. They add some visual interest without committing to one strong colour across the whole blind.
The woodline finish deserves a mention here too. It’s the one aluminium finish built specifically to answer a different question: real wood, or the look of wood? With woodline you get the aluminium slat width and its lower weight, but a printed grain that reads as timber from normal viewing distance.
Choosing tilt control for your aluminium Venetian blind
How you tilt the slats matters day to day. A wand feels different to use than a cord, and which one suits you best can depend on the blind’s size and where it’s fitted. Rather than guess from a list of generic options, raise this directly with whoever measures your windows. See the mechanisms in person. Choose the one that feels right for daily use, especially if the blind is opened and closed often, or sits within reach of children. A window above a cot, a low sill in a play room, or anywhere a cord could hang within reach is worth flagging during the home visit, so the fitter can set the control at a sensible height and point you towards the right mechanism for that spot.
Aluminium Venetian blinds fitting service across London
We fit every aluminium Venetian blind we supply, as part of the same free consultation and measuring visit. Venetian blinds fitted across East London is where most of this work happens. Dagenham, Barking, Ilford, Romford, Stratford, Walthamstow, plus nearby Essex addresses, are all covered. Wherever you are in that area, the process is the same, and the full finish and colour range above is available on every order rather than a cut-down stock list.
Once your blinds are up, a little regular care keeps the finish looking sharp. We’ve covered keeping aluminium slats clean in its own guide, so we won’t repeat it here. One thing worth knowing now: a lighter, brighter finish shows dust sooner than a darker one. Worth bearing in mind if easy upkeep matters more to you than the exact shade.
