A new insulated conservatory roof in Chester costs from £3,000 on a compact lean-to, while a typical spend is £3,000 to £7,500. With Chester's weather, replacing a 12 m² polycarbonate roof with our 75 mm panels holds on to roughly 1,008 kWh of heat a year, about £265 if you warm the room with an electric heater.
Chester has averaged 1,871 heating degree days a year since 2021. Multiply that by a roof's U-value and its area and you get the heat a conservatory roof throws away, which is where our numbers below come from.
The Chester climate, in four numbers
We took these averages for 2021 to 2025 from Open-Meteo's historical weather records for Chester. The warmest day in that spell hit 35.9°C on 19 July 2022. Inside a conservatory with a clear roof the air gets much hotter than that, so the room is too warm in July as well as too cold in January.
How much heat a new roof keeps in Chester
To get yearly heat loss we multiply three numbers: the roof's U-value, its area in square metres and the local degree days. Below are the results for an average 12 m² roof in Chester:
Worked out from Chester's 1,871 heating degree days (Open-Meteo, 2021 to 2025) and typical U-values.
| Roof type | U-value | kWh lost a year | Electric heater | Gas boiler |
|---|---|---|---|---|
| 16 mm polycarbonate | 2.3 | 1,239 kWh | £326 | £110 |
| Eco Tech 75 mm panels | 0.43 | 232 kWh | £61 | £21 |
| Difference | 1,008 kWh | £265 a year | £89 a year |
Energy costs use the Ofgem cap for 1 October to 31 December 2026. If the conservatory is never heated, the gain shows up as comfort rather than a lower bill: the room simply stays nearer to the rest of the house.

Chester questions, answered
What does a new conservatory roof cost in Chester?
Most of our Chester customers pay between £3,000 and £7,500. A medium Edwardian of around 17 m² usually comes to £4,200 to £4,950 with the old roof removed, the panels fitted and the 10 year HomePro warranty included. Your survey fixes the price in writing.
How much heat escapes through a conservatory roof in Chester?
On 1,871 degree days a year, a heated 12 m² roof in 16 mm polycarbonate loses around 1,239 kWh. Put 75 mm Eco Tech panels on the same frame and that drops to about 232 kWh.
Will I need planning permission in Chester?
Normally no, because the conservatory keeps its footprint and height. Listed homes, conservation areas and properties with permitted development rights removed should check with the council before work starts.
How quickly can Eco Tech fit a roof in Chester?
Our surveyors cover Chester as part of regular visits to North West. Most roofs go on a few weeks after the survey, and a typical roof is finished in one day.
