The UK Commercial Solar Hub
The specialist commercial solar installer for UK businesses
Commercial solar panel installation is the design, supply, planning, and commissioning of rooftop or ground-mounted PV systems for UK businesses with annual electricity demand above 50,000 kWh. A typical commercial system is 30 kW to 1 MW, sits on the host's own roof, exports surplus power to the grid via a G99 connection, and earns back its capital cost through avoided import charges within four to seven years. Unlike domestic installs, commercial projects require a structural roof survey, a half-hourly meter data analysis, a Distribution Network Operator (DNO) connection application, MCS or RECC certified design and signoff, building control sign-off where required, and full compliance with G99 grid protection standards. Project values typically span £30,000 to £1m+, and most are funded outright, financed via asset finance, or delivered under a Power Purchase Agreement (PPA) where the installer retains ownership and sells the energy back at a discount. This site is the SEO Dons hub for commercial solar across every UK property type — factories, warehouses, schools, hotels, hospitals, churches, farms, data centres, and offices — with specialist sub-sites for each.
UK commercial solar adoption has accelerated sharply since 2021, driven by grid electricity costs that more than doubled and corporate net zero commitments with binding 2025–2030 milestones. For commercial property owners, the economics now strongly favour on-site solar across most viable building types.

The Process
How we deliver your project
From free desk feasibility to commissioned system — a transparent four-phase process with one accountable contract.
01
Free desk feasibility
We pull your half-hourly meter data and roof drawings, model the system in PVSyst, and return an indicative proposal. No site visit, no charge.
02
On-site survey
If the numbers work, our engineers attend a 1-day structural and electrical survey. Final design and fixed-price proposal follow within 5 working days.
03
Permits and DNO
We handle planning (where required), G99 grid connection application, structural sign-off, and any grant paperwork. One contract — we manage the rest.
04
Install and commission
2–10 weeks on site. Final commissioning, monitoring activation, MCS handover pack. 25-year output warranty starts on commissioning day.
Real Concerns, Real Answers
Pain points we hear most often
- Energy bills doubling or tripling since 2021 with no end in sight to volatility
- Investor or board pressure to publish a net-zero pathway with credible interim milestones
- Tenant expectation (under green leases or B-Corp programmes) of renewable supply
- Customer or buyer-side ESG questionnaires (CDP, EcoVadis) blocking sales without on-site renewables
- Retrofit planning permission risk and DNO grid connection delays threatening project timelines
- Capital approval cycles taking 9-18 months while energy costs continue to escalate
- Cowboy installer market — 30%+ of commercial installs fail one or more MCS audit checks per industry data
Common objections — what the data actually shows
"It's too expensive — the capital cost wipes out our payback."
Most UK commercial solar projects pay back within 4-7 years on capital purchase. PPA finance removes upfront cost entirely; you pay for the energy generated at a fixed rate below grid, and the installer owns the system. Asset finance over 5 years is typically cash-flow positive in month one — the energy savings exceed the monthly finance repayment from day one.
"We've heard the panels degrade quickly and we'll need to replace them."
Tier-1 panels (Trina, JA, Longi) are warranted to retain 87% of rated output at year 25 and 80% at year 30. Real-world UK fleet data suggests degradation runs at 0.4% per year — better than warranty. The inverters typically need replacing once at year 12-15 (£3-8k for a commercial system), and that cost is included in our 25-year proposals.
"Our roof isn't strong enough."
We commission a full structural calculation as part of every commercial proposal — covering dead load, wind uplift, and any imposed snow load per BS EN 1991. If a roof can't take the array, we tell you in writing and charge nothing for the desk feasibility. Solutions for marginal roofs include lightweight east-west systems, ballasted ground-mount on adjacent land, or solar carports over the staff car park.
"What if we sell the building?"
Most commercial solar systems are recognised as a building improvement and increase EPC rating, which lifts asset value. If you fund through PPA, the contract is novated to the new owner — at a fixed rate below grid, this is usually a benefit, not a liability. We've supported several portfolio sales where the solar contract added measurable value to the disposal.

Compliance Built In
UK commercial solar compliance — what every install must hit
Commercial solar installation is one of the most regulated areas of the construction industry — every install crosses building regulations, electrical regulations, grid code, health and safety, and frequently planning. We deliver every project against this compliance stack as the baseline, not as a stretch.

300 kW rooftop install on a Tier-1 automotive supplier in the West Midlands
Our client operates a precision-engineered components plant running double-shift 6 days a week. Annual electricity demand was 1.4 GWh against escalating £140k-plus quarterly bills. We modelled the existing 4,500 sqm composite roof from drawings, ran a structural recalculation against the original 1998 design, and proposed a 300 kW system with 92% self-consumption and a 4.8-year payback.

Common questions about commercial solar
Get straight answers to the questions UK businesses ask most often.
How much does commercial solar panel installation cost in the UK?
UK commercial solar installation costs range from £700/kW for very large (1MW+) ground-mount projects to £1,200/kW for smaller (50-100kW) rooftop installs. A typical 100 kW commercial system costs £80,000-£120,000 fully installed including DNO application, structural design, MCS sign-off, and 25-year warranty. Battery storage adds approximately £700 per kWh of storage. Most projects are funded outright via capital purchase, asset finance over 5 years, or zero-capital PPA.
How long does commercial solar panel installation take?
From signed contract to energised system typically takes 8-16 weeks for a roof-mounted commercial install. The phases are: design and DNO application (3-5 weeks), procurement and lead times (4-6 weeks), on-site install (2-4 weeks for a 100-300 kW system), and commissioning (1 week). Larger projects above 500 kW or those requiring planning permission can take 4-6 months end to end.
What is the payback period on commercial solar?
Payback periods on commercial solar in the UK range from 4 to 9 years, depending on self-consumption ratio, DNO export agreement, and capital cost route. A factory or hospital with continuous shift demand and 90%+ self-consumption typically pays back in 4-6 years. A warehouse or office with weekday-only demand and 50% self-consumption pays back in 7-9 years. Battery storage shortens payback for sites with high evening or weekend demand.
Do I need planning permission for commercial solar panels?
Most commercial roof-mounted solar installations are permitted development under Class J of the General Permitted Development Order, provided the panels do not project more than 200mm above the roof slope. Ground-mounted arrays above 50 kW require full planning permission. Listed buildings and conservation area sites require listed building consent regardless of size. We handle all planning applications as part of the standard service.
What size solar system does my business need?
We size commercial solar systems to consumption rather than to roof. A typical UK business uses around 50,000-200,000 kWh per year and needs a 50-200 kW solar system to offset 60-80% of grid imports during daylight hours. We pull your half-hourly meter data, model the system against actual demand, and recommend the size that maximises self-consumption rather than the largest system the roof can support.
What grants are available for commercial solar in the UK?
The main UK commercial solar grants are: Public Sector Decarbonisation Scheme (PSDS) for public sector estates, Industrial Energy Transformation Fund (IETF) for manufacturing, and Low Carbon Skills Fund (LCSF) for feasibility work. Annual Investment Allowance allows 100% first-year capital deduction up to £1m on solar PV as plant and machinery. Power Purchase Agreement (PPA) financing requires zero capital and is available to any creditworthy commercial site.
