See when local sunshine is likely to cover an air conditioner, what a typical solar array can generate, and which energy schemes serve Nottingham. The forecast updates through the day. The long-term figures come from the European Commission's PVGIS dataset.
Long-term local picture
PVGIS models a south-facing system at 35 degrees with 14% system losses. It is a consistent way to compare towns, but your roof direction, shade and equipment will change the result.
Representative climate year
The PVGIS typical meteorological year has an average July daily high of 22.3°C, with 8 days reaching at least 25°C and 72 hours at or above 24°C across the representative year.
How to size the system
Local weather helps estimate running hours. It does not size an air conditioner. An installer still needs room area, glazing, orientation, insulation, occupancy and external-unit constraints before specifying equipment.
Current support
Air-to-air heat pumps joined the scheme at £2,500 from 21 July 2026. The system must provide heating, meet scheme and MCS requirements, and replace an eligible existing heating system. Cooling-only air conditioners do not qualify. The installer applies and passes the grant on as an upfront discount.
Read the scheme guide →This is delivered through local authorities and availability varies locally. Eligible owner-occupiers can receive an agreed package without paying for the approved work. Qualification does not guarantee a particular measure: the council arranges a survey and decides what is suitable and available.
Read the scheme guide →ECO4 has been extended to 31 December 2026. It is not a general air-conditioning grant and does not promise a fixed package. The supplier or delivery partner assesses the household and property, then selects eligible measures under the scheme rules.
Read the scheme guide →These are planning guides, not fixed local quotations. Roof access, cable runs, room load and equipment choice can move the installed price.

Approximation for one 0.9 kW air conditioner running when the forecast reaches 24°C, paired with a 3.5 kWp array. Solar output is modelled from sun position and cloud cover. Electricity is costed at 26.11p/kWh, the Ofgem average capped unit rate for July to September 2026. Forecast data from MET Norway ↗.
