This sets how much roof there is to work with.

2 of 4How many bedrooms?

A quick guide to how much electricity the house uses.

3 of 4What is the roof like?

Flat roofs get tilted frames held down with weight, so nothing is drilled.

4 of 4Add battery storage?

A battery stores the afternoon for the evening, which is when cooling and cooking happen.

    Solar panels give the house a supply of electricity of its own, alongside the grid.

    Solar questions

    How much do solar panels cost in London?

    A typical London three-bedroom house takes about eleven panels, a 5.1kWp system. Our 2026 quotation for eleven panels and two batteries was £9,774, and our quotations for eight to eleven panels with two batteries came to £9,347 to £9,940, all with 0 percent VAT. Panels on their own cost less: our five-panel quotation, with no battery, was £3,798. Our largest, 28 panels with a Tesla Powerwall 3, came to £16,500.

    Scaffolding is the item that varies most in London, because a three-storey terrace with no rear access costs considerably more to scaffold than a suburban semi. Where a roof needs it, it is its own line on the quotation.

    Is my roof any good for solar in London?

    South facing is best, but east and west facing roofs in London produce about 80 to 85 percent of a south facing roof and are usually still worth doing. A north facing roof alone is not.

    What actually kills a London roof for solar is shading: a neighbour's chimney, a large tree or a taller building next door. Shading on one panel drags down a whole string unless the system is designed with optimisers, which is why we look at the roof before quoting rather than after.

    Do solar panels need planning permission?

    Usually no. Roof-mounted panels on a house are normally permitted development provided they do not project more than 200mm from the roof plane, do not sit above the highest part of the roof, and are removed when no longer needed.

    In a conservation area they must not be on a wall or roof slope facing a highway. On a listed building you need listed building consent regardless. Flat roof and ground mounted arrays have their own conditions.

    How much of my electricity will solar provide?

    A 4kWp London system generates roughly 3,400 to 3,800 kWh a year. Without a battery you will typically use about 40 to 50 percent of that yourself and export the rest.

    With a battery, the share you use yourself rises to around 70 to 85 percent. What that is worth depends on your tariff and how you use electricity, so we work it through with you at the survey rather than promise a figure.

    Do I get paid for the electricity I export?

    Yes, through the Smart Export Guarantee. Every large energy supplier must offer an export tariff, and rates vary a lot between them, so it is worth shopping for the export tariff rather than accepting whatever your current supplier offers.

    You need an export meter, which for most homes means a smart meter, and an MCS certificate for the installation. We issue the MCS certificate as part of the job.
