The conservatory problem

Most UK conservatories have the same three problems.

Polycarbonate conservatory roofs age badly. Within 8–10 years the sheets yellow, algae grows between the twin walls, and the noise of rain becomes unbearable. In summer the room is a greenhouse; in winter it's colder than the garden. Condensation drips from the underside every morning.

Replacing the whole roof with a solid tiled one costs £6,000–£15,000, needs planning permission in most cases, and takes weeks. For most people, that's not on.

A PVC ceiling fitted underneath the existing polycarbonate does most of the same job for a fraction of the cost — waterproof, insulating, and it hides the yellowed roof completely. No planning permission, no builders, no scaffold.

Yellowed roof
PVC panels hide old polycarbonate completely — clean matte white, or wood effect for warmth.
Freezing in winter
The air gap between panels and roof acts as insulation. Add loft roll behind the panels for full thermal upgrade.
Loud rain
Panels + insulation muffle the drumming rain that ruins polycarbonate roofs during a downpour.
Fitting the panels

Four steps to a proper conservatory ceiling.

Step 1
Batten the roof bars
Screw treated 25 × 38mm battens perpendicular to the existing roof bars at ~500mm centres. Use existing bar screws where possible.
Step 2
Add insulation (optional)
Loft roll or foil-backed foam between the battens for a proper thermal upgrade. Skip for basic hide-the-roof jobs.
Step 3
Clip in the panels
Panels tongue-and-groove into each other. Staple, pin or grab-adhesive to the battens. Work from one side toward the other.
Step 4
Trim the edges
End caps or coving hide the cut ends. Silicone the perimeter for a clean, sealed finish.
Ceiling + coving = finished

Don't forget the trims.

Panels only cover the ceiling — you'll want matching PVC coving to finish the wall-to-ceiling joint, and end caps for any cut edges around vents, lights or the ridge bar.

Common questions

Conservatory ceiling FAQs.

Can I fit these straight over polycarbonate?
Yes — the standard install is battens screwed to the existing polycarbonate roof bars, then panels clipped to the battens. The polycarbonate stays in place doing its waterproofing job; the PVC ceiling sits underneath.
Will it help with the heat in summer?
Yes, substantially. The air gap between panels and roof, plus optional loft-roll insulation, blocks the greenhouse effect from direct sunlight. Customers typically report the room becoming 4–8°C cooler on hot days.
Do I need to keep some windows for airflow?
Yes — leave existing roof vents functional, or install one or two ceiling vents through the panels. Sealed conservatories need controlled airflow to prevent trapped condensation between the panels and the polycarbonate.
Does it need planning permission?
No. Because the existing roof stays in place and you're only fitting an interior finish, planning permission and building control approval don't apply — this is decoration, not a structural change. If in doubt, check with your local building control officer.
Can I do it myself?
A confident DIYer with a helper can typically complete a 3m × 4m conservatory in one day — half a day for battens, half a day for panels and trims. Panels cut with a fine-tooth saw or sharp Stanley knife. See our Install Guide.
How do I work out how many packs I need?
Each panel covers 0.65 m² (2.6m × 0.25m). Measure your conservatory ceiling area in metres, divide by 0.65, round up, and add ~10% for cutting waste. Or use our free Panel Calculator — enter the dimensions and it works out the exact packs.
Will the panels yellow like polycarbonate?
No — they're indoor-side facing, so they're not exposed to direct UV. PVC ceiling panels installed inside a conservatory (below the roof) typically look the same after 15+ years as the day they went up.
