What Newcastle-under-Lyme weather does to a conservatory
The grid reads like a calendar turned on its side: months down, hours across, colour for the average room temperature. Newcastle-under-Lyme's warmest month outdoors was August at 16.5°C on average, with a top of 30.1°C, yet a polycarbonate conservatory peaked at 47°C because the roof traps the midday sun.

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 Newcastle-under-Lyme that is 3,947 a year under polycarbonate and 4,900 under an insulated panel roof, roughly 953 hours handed back.
The worst hours, above 30°C, fall from 412 to 20. A glass roof manages 561.

When the heat peaks in Newcastle-under-Lyme
June is the problem month here: 35% of its waking hours top 28°C under polycarbonate, 4% under panels. Spring and early autumn matter too, when the sun is still strong but nobody expects to open the doors.

Winter in Newcastle-under-Lyme
Winter here bottoms out in January at an average of 3.2°C (coldest hour -5.5°C). Keeping 19°C while the room is in use costs about £488 a year in electricity under polycarbonate and £410 under the panel roof, 1,855 against 1,557 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.

Plan on a single day for most Newcastle-under-Lyme 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.
