About Commercial Solar Cost UK
This site exists to answer one question properly: what does commercial solar actually cost in the UK right now?
Why a site about cost, specifically
Most commercial solar websites treat price as a secret to be revealed after a sales visit. The result is predictable: facilities managers and finance directors spend weeks collecting incomparable quotes, each built on different scopes, different assumptions and different omissions. We publish the 2026 pricing curve openly — £650 to £1,100 per kWp depending on size and site — along with the nine factors that place any given project within it. If you arrive at a supplier conversation already knowing the band, the conversation gets honest much faster.
Where our numbers come from
The figures on this site are maintained against live UK project pricing: installer tender returns, component trade pricing, DNO application outcomes and published scheme rules. We update the bands when the market moves, not on a marketing calendar. Where a figure is directional rather than precise — regional energy rates, for instance — we say so in the text rather than dressing an estimate as a promise.
What happens when you request a quote
The quote form asks for your property type, rough roof or energy-spend figures and a postcode — about two minutes of effort. From that, plus half-hourly meter data if you can share it, a desk feasibility is built: modelled system size, yield, self-consumption, indicative price band and funding comparison. No site visit is needed for that first pass, and no one telephones you out of the blue — everything starts in writing, by email.
If the indicative numbers work for you, the project moves to a structural and electrical survey by an MCS-certified installation team, which converts the band into a fixed price with a written scope. If the numbers don't work — roof too shaded, supply too constrained, consumption too low — you get told that plainly. A solar system sold to an unsuitable site fails everyone, including us.
Accreditation and delivery standards
All installation work arranged through this site is delivered by MCS-certified commercial teams, with NICEIC-registered electrical contractors, RECC-aligned sales practice and insurance-backed workmanship warranties. Design work follows the conventions lenders expect: PVSyst (or equivalent) yield modelling shared in full, G99 grid applications handled and witnessed, and structural sign-off on every roof before a single rail goes up.
What we don't do
No urgency theatre — solar prices are not "ending Friday". No phone-number harvesting; the process is form-first and written. No payback claims invented from national averages when your half-hourly data is what actually decides the answer. And no pretending VAT, DNO reinforcement or inverter replacement doesn't exist: the costs that surprise people on other sites are documented here in the FAQs.
