What Wokingham weather does to a conservatory
We ran Wokingham's hourly weather for 2024 and 2025 through the same room three times, once per roof. The squares are hour by hour averages. The garden never beat 31.7°C and July averaged 18.5°C, but the polycarbonate room touched 48°C, against 35°C with panels.

The hours you get back
A heater can rescue a chilly hour. Nothing cheap rescues a 31°C one. So the useful measure is how many waking hours stay at or under 25°C: in Wokingham that is 3,656 a year under polycarbonate and 4,685 under an insulated panel roof, roughly 1,029 hours handed back.
The worst hours, above 30°C, fall from 683 to 72. A glass roof manages 851.

When the heat peaks in Wokingham
June is the problem month here: 52% of its waking hours top 28°C under polycarbonate, 11% under panels. Spring and early autumn matter too, when the sun is still strong but nobody expects to open the doors.

Winter in Wokingham
Winter here bottoms out in January at an average of 4.3°C (coldest hour -4.9°C). Keeping 19°C while the room is in use costs about £393 a year in electricity under polycarbonate and £339 under the panel roof, 1,494 against 1,288 kWh.
We would not sell the roof on that difference alone. The glass walls keep losing heat either way; what changes most is that the room stops cooking in summer and a smaller heater copes in winter.

Fitting day
Plan on a single day for most Wokingham roofs, usually a second for a P-shape. We take the old roof away the same day and leave the room swept. The fitting day walks through it hour by hour.
