Conservatories are notoriously difficult spaces to use comfortably without effective blinds. In summer, an unshaded polycarbonate or glass roof turns the space into an oven; in winter, single-glazed panels bleed heat. Well-chosen blinds significantly extend the usable season of a conservatory without the cost of a full orangery conversion. This guide sets out the main blind types, realistic 2026 costs, and what to prioritise when choosing.
The Problem Conservatory Blinds Solve
A standard polycarbonate-roofed conservatory can reach 35–40°C in summer on a south-facing elevation — well above comfortable working or relaxing temperature. Glass roof conservatories have similar solar gain issues. On the other side, at night and in winter, the large glazed area loses heat rapidly.
Blinds address both problems:
- Solar control: reflective or opaque fabrics block direct sunlight and reduce solar gain by 60–85%, depending on fabric openness and reflectivity.
- Thermal retention: honeycomb (cellular) fabrics trap a layer of insulating air next to the glass, reducing nighttime heat loss.
No blind fully replaces proper insulated glazing, but in a polycarbonate conservatory they are the most cost-effective improvement available.
Types of Conservatory Blind
Pleated Blinds
The most common conservatory blind type for roof panels and awkward angles. A pleated fabric is concertina-folded and runs on side channels, allowing it to be pitched at any angle. Works well on lean-to roofs, Victorian ridged roofs, and non-rectangular panels. Available in many fabric types from sheer to blackout.
Pinoleum Blinds
Made from thin wooden slats woven with polyester, pinoleum gives a warm, natural aesthetic and effective diffusion of harsh sunlight without complete blockout. Very popular for Victorian-style conservatories. Not suitable for areas with high humidity as the wooden slats can warp.
Perfect-Fit Blinds
A frame clips directly onto the inner edge of the window beading, and the blind operates within the frame — no cords trailing and no drilling into the UPVC. Available in pleated, cellular, and venetian styles. Particularly good for side and gable panels.
Roller Blinds (Conservatory-Spec)
Standard roller mechanism adapted for conservatory use. Suitable for vertical side panels only — not roof slopes. Simpler than pleated and usually cheaper, but limited to vertical applications.
Venetian Blinds
Timber or aluminium slats on a standard venetian mechanism. Good for side panels and gables. Not suitable for roof pitches. Timber venetians are not appropriate for humid conservatories.
Electric/Motorised Blinds
Any of the above types can be motorised. Roof blinds in particular benefit from motorisation — operating multiple interconnected roof panels manually is awkward. Electric systems typically add £100–£200 per blind. Smart controls (app, voice, or timer) add a further premium. Electric systems require a 240V supply run to the conservatory roof — if this is not present, allow for an electrician.
Cost Guide
Prices below are for supply and professional installation. DIY kits are available (typically 25–35% cheaper) but fitting roof blinds to a Victorian ridged roof is physically awkward.
| Blind Type | Roof Panel (each) | Side/Gable Panel (each) |
|---|---|---|
| Pleated — standard fabric | £150–£280 | £80–£160 |
| Pleated — solar reflective | £200–£350 | £100–£200 |
| Pinoleum | £180–£320 | £90–£180 |
| Perfect-fit cellular | £130–£250 | £80–£160 |
| Roller — standard | Not applicable | £70–£140 |
| Venetian (aluminium) | Not applicable | £80–£160 |
| Motorised uplift (per blind) | +£120–£220 | +£100–£180 |
Typical full conservatory (8 roof panels, 6 side panels, 1 gable): £3,000–£6,500 professionally installed, depending on blind type and motorisation.
What Makes a Good Conservatory Blind?
UV resistance. Conservatory fabrics are exposed to intense UV year-round. A blind not rated for UV exposure will fade and degrade within 2–3 years. Look for fabrics with 5+ year UV warranty.
Moisture tolerance. A conservatory can be a humid space. Avoid real wood slats and untreated cotton or linen fabrics in poorly ventilated conservatories.
Solar performance data. Reputable suppliers provide an openness factor (0–10%) and a solar reflectance figure for each fabric. Higher reflectance = more solar gain blocked. For a hot south-facing conservatory, prioritise fabrics with >60% solar reflectance.
Thermal performance. Cellular (honeycomb) fabrics have a measurably better U-value when deployed next to glass. If winter heat retention is important, prioritise cellular over pleated or pinoleum.
Child safety. All blinds supplied in the UK should comply with the Child Safety from Risks Posed by Corded Internal Window Coverings Regulations 2014. Ensure any cords are fitted with a breakaway safety device or are out of reach.
Measuring for Conservatory Blinds
Each panel must be measured individually — conservatories are often not perfectly uniform, and panels that appear identical frequently differ by 5–20 mm. Measure the width at three points (top, middle, bottom) and use the smallest dimension. For roof panels, measure along the slope, not the horizontal run.
Most professional conservatory blind companies offer a free measurement and quotation visit. If you are using an online supplier, their measure-it-yourself templates are usually accurate provided you follow the instructions carefully.
Installation Notes
Roof blinds are fitted to the roof bars (purlins) of the conservatory frame, not to the glass. The supplier should confirm compatibility with your frame type before ordering. Installation typically takes a half day for a small lean-to and a full day for a large Victorian-style conservatory.
Electric blinds require either a pre-existing 240V circuit in the roof space (some conservatories have a junction box from the original installation) or a new circuit run from the consumer unit. An electrician charge for running a new circuit to the conservatory roof is typically £200–£400.
Are Conservatory Blinds Worth It?
For polycarbonate or single-glazed conservatories, yes — the improvement in thermal comfort is significant and the cost compares very favourably to replacing the roof structure with solid insulated panels (typically £8,000–£18,000). Well-maintained conservatory blinds last 8–15 years with normal use.
If your conservatory has an existing self-cleaning glass roof with an integral solar control coating, the case for blinds is less strong — check the U-value and solar transmittance of your glass first.
