We install solar panels, heat pumps and battery storage across Hampshire, Dorset, Wiltshire, Surrey and West Sussex — all within around an hour of our base in Eastleigh. Each page below covers what that town's roofs actually generate, who decides your planning application there, and which grid process applies.
Get a Free SurveyAn identical solar array produces about 15% more in Chichester than in Guildford. That is not a rounding error — it is the difference between two systems we would size and price differently. These are modelled figures for a south-facing roof at 35°; your own survey figure will differ with shading, pitch and orientation.

Ten of these eleven towns sit in SSEN's SEPD area — including Chichester, over in West Sussex. Guildford is UK Power Networks. The licence boundary cuts through Surrey rather than following the county line, and a grid application sent to the wrong operator is rejected rather than forwarded.
Hampshire's largest city, and its densest housing. Pre-1919 terraces, 20 conservation areas, and 1,080 kWh per kWp a year.
Solar & heat pumps in Southampton →The UK's most densely populated city outside London. The second-best solar yield we measure, 25 conservation areas, and widespread flood zones.
Solar & heat pumps in Portsmouth →37 conservation areas, a large listed stock, and part of the district under the South Downs National Park Authority rather than the council.
Solar & heat pumps in Winchester →Our nearest patch, and the third-best yield in the region at 1,117 kWh per kWp. 13 conservation areas and tidal flood risk on the coast.
Solar & heat pumps in Fareham →More conservation areas than any other district in Hampshire, alongside post-war estates that retrofit unusually well. Four Article 4 areas.
Solar & heat pumps in Basingstoke →Two towns in one: a Georgian conservation-area centre, and new estates at Augusta Park and Picket Twenty that are near-ideal for retrofit.
Solar & heat pumps in Andover →50.7% of households live in a flat — third-highest in England and Wales. Who owns your roof is the first question here.
Solar & heat pumps in Bournemouth →The most heritage-constrained place we work, and the villages around it are where the £9,000 off-grid heat pump grant does most work.
Solar & heat pumps in Salisbury →The best solar yield anywhere we install: 1,175 kWh per kWp. Also the most layered planning picture, with two-thirds of the district in the National Park.
Solar & heat pumps in Chichester →The one town on our patch served by UK Power Networks rather than SSEN. The lowest yield per kWp, but two-thirds of homes are detached or semi.
Solar & heat pumps in Guildford →Sandbanks, Canford Cliffs and Branksome Park are all conservation areas, so solar there usually needs planning permission.
Solar & heat pumps in Poole →
