Solar Panels Leatherhead

For most Leatherhead homes, no — roof-mounted solar is normally permitted development in England. The town centre is the exception worth taking seriously: its conservation area is one of only three in Mole Valley (with Dorking and Brockham) where an Article 4 Direction places additional planning controls over parts of the area, so roof alterations in the historic core need an extra check with Mole Valley District Council before anything is fixed. The wider district holds 26 conservation areas and more than 1,000 listed buildings, and listed buildings always need listed building consent — carrying out consent-needing work without it is a criminal offence, which is exactly why the planning check comes before our quote, not after.

UK Power Networks — the distribution network operator for London, the South East and East of England, whose area includes Leatherhead. A typical home system is notified to UKPN under G98 after installation, while larger systems need G99 approval from UKPN before the work starts. A common misconception is that this paperwork goes to your energy supplier; it doesn't — the supplier only becomes relevant when you set up an export tariff for the electricity you don't use. Your installer should handle the UKPN notification as a matter of course, so it's a question to ask when comparing quotes rather than a job for you.

Yes — Solar Together Surrey. Mole Valley District Council is one of 12 Surrey councils in the group-buying scheme, run with independent group-buying experts iChoosr, where vetted installers compete in a reverse auction to offer residents competitive prices on solar panels and battery storage. The council is also putting panels up itself: solar carports covering around 20 bays went in at Leatherhead Leisure Centre's car park from January 2026, expected to generate 37,498 kWh a year. Our honest advice on the group scheme is the same as for any quote — compare it line by line against an independent price on panel output, inverter, battery and warranty, and let the numbers decide.

Yes, and we can be specific without overselling it. The Met Office's long-term climate station at Wisley, about six miles from Leatherhead, averages 1,584 hours of sunshine a year on the 1991–2020 record — above the UK average — with a relatively dry 668 mm of annual rainfall. Panels generate from daylight rather than direct sun alone, so they keep producing at reduced output on overcast days. But no town's climate makes or breaks an install: your roof's orientation, pitch and shading matter far more than the postcode, which is why we assess the actual roof rather than quoting from a regional average.

We won't put a number on it without seeing your roof and your bills, because honest payback maths is specific to the house: array size, how much of the generation you use rather than export, your tariff, and whether a battery is included all move the answer. What the local data does suggest is favourable raw material — around 39.7% of KT22 properties are detached and 35.3% have four or more bedrooms, which tends to mean larger roofs and higher household consumption, and using more of your own generation is the single biggest lever on payback. A battery often strengthens that case by shifting daytime generation into evening use, but it adds cost and has to be sized honestly. We'll set out the arithmetic for your house, assumptions included, so you can check it yourself.

The honest national anchor is the Energy Saving Trust's: a typical domestic system is around 4.5 kWp — roughly twelve panels over 20 to 30 square metres of roof — and costs around £7,600 installed (their figure, updated 27 August 2026). Residential installations carry 0% VAT until 31 March 2027, reverting to 5% after that. Your roof's size, pitch and shading move the number far more than the town does. That is why we price from a survey of your actual roof and usage rather than from a table.

We ran the European Commission's PVGIS tool for Leatherhead itself rather than quoting a generic figure: a 4 kWp array at 35° facing due south, with 14% system losses, is estimated at about 4,006 kWh a year — around 1,001 kWh per kWp — with a year-to-year variation of roughly ±141 kWh (PVGIS 5.3, SARAH3 2005–2023). East- or west-facing slopes generate less, and shading changes the answer more than the town does.
