MCS-certified eco installers in South East England
The South East has the UK's highest concentration of MCS-certified eco installers, led by London and supported by large, affluent towns in Hampshire, Berkshire, Kent and beyond. Good solar irradiance across the region, high electricity prices and strong property values make solar plus battery storage among the most financially compelling eco investments in the UK. Access to all national grants applies across the South East.

Solar potential and returns in the South East
The South East benefits from above-average solar irradiance — particularly along the Hampshire and Kent coasts. A south-facing 4kWp system in Southampton or Reading generates roughly 3,400–3,800 kWh/year. London's higher electricity prices and property values make solar investment particularly attractive, and the large number of installers in the capital gives homeowners strong competitive choice. Battery storage maximises the value of solar generation in the busy commuter-belt lifestyle.
London's unique considerations
London has the UK's densest concentration of MCS-certified eco installers — but also the most complex installation landscape. Conservation area restrictions, shared roofs in mansion blocks, and planning considerations for some London boroughs mean specialist knowledge matters. Labour costs in London run 10–20% above the national average, making it especially important to compare multiple installer quotes. The £350 OZEV EV charger grant for renters and flat owners is particularly relevant in London's high-renter housing market.
Common questions
Can I get solar panels in London?
Yes. Many London properties — particularly Victorian and Edwardian terraces in suburbs, and detached or semi-detached properties — are well-suited to solar PV. Conservation areas and listed buildings may restrict panel placement, but most properties are not affected. MCS-certified London installers are experienced with conservation area constraints.
What eco grants are available in the South East?
All national grants apply: Boiler Upgrade Scheme (£7,500 for heat pumps), ECO4 (free upgrades for eligible low-income households), GBIS (subsidised insulation for band A–D homes with EPC D or below), and the OZEV EV charger grant (£350 for renters and flat owners). Additionally, some London boroughs run local retrofit grant schemes — check with your installer.
Are heat pumps suitable for semi-detached houses in the South East?
Yes — modern semi-detached properties (particularly post-1930) are generally well-suited to air-source heat pumps, particularly when loft and cavity wall insulation are in good condition. An installer survey will calculate your home's heat loss and confirm suitability. The Boiler Upgrade Scheme's £7,500 grant significantly reduces the upfront cost.
