What Bridgwater 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. Bridgwater's warmest month outdoors was August at 17.9°C on average, with a top of 31°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 Bridgwater that is 3,716 a year under polycarbonate and 4,811 under an insulated panel roof, roughly 1,095 hours handed back.
The worst hours, above 30°C, fall from 623 to 25. A glass roof manages 791.

When the heat peaks in Bridgwater
July is the problem month here: 51% of its waking hours top 28°C under polycarbonate, 6% under panels. Spring and early autumn matter too, when the sun is still strong but nobody expects to open the doors.

Winter in Bridgwater
Winter here bottoms out in January at an average of 5.1°C (coldest hour -4.2°C). Keeping 19°C while the room is in use costs about £364 a year in electricity under polycarbonate and £321 under the panel roof, 1,383 against 1,221 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 Bridgwater 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.
