One window or the whole wall
Updated
The first opening is the expensive one because the visit, the van and the design are in it. The second and third on the same elevation are often better value on the same day.
The number
Do not invent extra windows to chase a discount if they face north and you do not care about them.
Fitted illustration for One window or the whole wall in Wolverhampton: £3,215 at September 2026 prices, for this 3.2 by 1.2 m opening with a wired motor. The figure allows a front-mounted aluminium curtain and ordinary fixing. It does not include scaffold, a rebuilt soffit, planning drawings, or a new window. A second opening on the same visit usually costs less than the first, because the van is already there. Compare two quotes only when the slat, the box and the drive match.
- wired motor on a 3.2 by 1.2 m opening
- Colour as a RAL or foil reference, not a dusk photo
- Scaffold, electrics and making good listed or excluded
- Lanterns and side lights named or left out
What the watts are doing
The worked opening for One window or the whole wall is 3.2 m wide by 1.2 m high, 3.84 square metres of glass. This figure puts 595 watts per square metre on the pane and uses a g-value of 0.7, about 1599 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 85 percent of that gain while it is fully down, leaves about 240 watts and keeps about 1359 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For One window or the whole wall, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
Night-time, priced as comfort
Winter figure for One window or the whole wall: glass at 1.4 W/m2K, 3.84 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.52 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.39 kWh and saves about 0.12 kWh a night, only while it is down. Open it when you want winter sun.
Lines that should be extra
Stop One window or the whole wall if the solar panel would sit in a soffit with no sky, and the quote has no wired alternative. A photograph is not a manufacturing size.
How to use the figure
The 3.2 by 1.2 metre opening inside One window or the whole wall is there so a quote has something to disagree with. If the tape gives a different size, the tape wins.
The example drive is a wired motor, and the illustration is £3,215. A belt, a wired motor and a solar motor can share a curtain and still be different jobs. Compare those lines, not a single bold total.
What the survey still has to write down
For One window or the whole wall, ask where the box lands, what colour reference will be ordered, and how the curtain opens when the motor is dead. Those three answers move the job more than a rounded price.
Leave the lantern, the side light and the next elevation off the order unless they are drawn. One window or the whole wall covers one kind of opening. The house may have three.
When I would not order yet
One window or the whole wall should wait if the opening is an escape door with no way to raise a dead motor, or if the front is the elevation a conservation area was drawn to protect.
A photograph is not a manufacturing size. Two quotes for One window or the whole wall only compare when the slat, the box and the drive are the same kind of thing.
Questions worth asking the fitter
Is the price on this page a quote?
No. £3,215 illustrates One window or the whole wall for a 3.2 by 1.2 metre opening with a wired motor, at September 2026 rates. Your survey replaces it.
Does the shutter cover every pane?
It covers the opening it is built for. Here that example is 3.84 square metres. A roof lantern, a side light or the next elevation is another line.
What if planning is unclear?
Do not pay the factory for One window or the whole wall until a listed building, a conservation front, a flat or a shopfront has a written answer. Ordinary rear walls on houses are sometimes simpler.
What should two quotes share?
The same openings, the same slat type, and the same drive. One window or the whole wall uses a wired motor in the example so you can see how much the motor choice moves £3,215.
