Solar Panel Installers in London

Look for MCS certification (non-negotiable — it's required for the 0% VAT rate and Smart Export Guarantee), plus RECC and TrustMark membership for consumer protection. Beyond the badges, the differentiators in London are real local install experience (terraced-street scaffolding, conservation-area design), an in-house team rather than subcontracted labour, and aftercare you can actually phone. Sola UK is MCS, RECC and TrustMark certified with 700+ installs across North London and Hertfordshire. We're happy to put you in touch with a recent customer near you before you decide — and our best-solar-companies-in-London guide explains exactly what to compare.

A typical 4kW system for a London home costs around £7,000–£9,500 fully fitted, and a larger 5–6kW system runs £8,500–£16,500 depending on roof and battery. London prices sit roughly 10–20% above the UK average, mostly because of scaffolding and access (£800–£1,500 vs £400–£800 nationally) plus parking suspensions on terraced streets. Our quotes include scaffolding and certification — no hidden extras. Use our ROI calculator for a personalised estimate.

Usually not. Most London installs go ahead under permitted development rights, provided panels don't project significantly from the roof and aren't on a wall visible from a highway. The London exceptions are conservation areas and Article 4 directions (common in Camden, Haringey and parts of Barnet) — if your property has an Article 4 direction, you'll likely need a planning application, especially for any street-facing array. We design onto non-street-facing slopes to keep most jobs inside permitted development, and we prepare the application for you when one is genuinely needed.

Yes — and counter-intuitively, London payback (5–7 years) often beats sunnier regions. London irradiance is slightly below the southern-England best (around 1,000–1,050 kWh per kW per year), but London electricity tariffs are among the highest in the UK (roughly 27–32p per kWh in 2026), so every self-consumed unit saves more. Over a 25-year panel lifespan, a typical London system delivers strong lifetime savings, and adding a battery pushes self-consumption from ~30–50% to 70–90%.

Our core coverage is North London — Barnet, Enfield, Haringey, Camden, Islington, Hackney, Waltham Forest and Tottenham (N1–N22, EN1–EN5) — where our St Albans base gives the fastest survey and aftercare response. We also serve East, West and northern South London on a job-by-job basis, plus the Hertfordshire–London fringe. See our North London hub for borough-level detail.

Yes — Victorian and Edwardian terraces, which dominate much of North and East London, are well suited to solar. Most have a rear-facing roof slope that's ideal both for output and for conservation-area discretion. A standard mid-terrace typically takes 8–12 panels on the rear slope (around 3–5kW). We fit Aiko 485W all-black panels that sit low and look discreet on period roofs, and we plan scaffolding around tight terraced access.

Solar panels and home battery storage currently qualify for 0% VAT under the UK's energy-saving materials relief — a meaningful saving versus 20% standard VAT. As of 2026, this relief is scheduled to run until 31 March 2027, after which it's set to revert to 5% unless extended; battery storage has been included at 0% since 1 February 2024. Because tax policy changes, always confirm the current rate with us at the point of quoting rather than relying on a figure in any guide.

The Smart Export Guarantee (SEG) pays you for surplus electricity exported to the grid. Rates are set by individual suppliers and change frequently — they move month to month, so we'd point you to live tariffs rather than a fixed number here. Our SEG calculator estimates your likely export income. For most London homes the larger benefit is self-consumption, which a correctly sized battery maximises, so we design around using your own generation first and exporting the rest.
