Commercial Solar Panel Installation Across the UK

Commercial solar is what we do, end-to-end, across the UK. We design and deliver complete commercial solar projects for businesses from 25 kW SME installs through to 1 MW+ industrial campuses and ground-mount arrays. Every project is modelled against your half-hourly meter data, designed against PVSyst yield runs, financed against your specific tax position, and delivered with proper project management — not a postcode-and-a-guess quote followed by a series of expensive change orders. This page covers what we deliver, the sub-verticals we specialise in, our geographic coverage, the four-step delivery process, and the trust signals that matter when picking a commercial PV partner.

What we deliver — end-to-end, not just install

A complete commercial solar project covers far more than the kit on the roof. We deliver six tightly-integrated workstreams on every project. Design: full PVSyst yield modelling, structural and electrical engineering, DNO connection design, layout optimisation against your roof geometry and shading, and 25-year DCF financial modelling. Supply: tier-1 panel, inverter, mounting and switchgear procurement direct from manufacturers, with serial-number traceability and full warranty registration on every component. Installation: MCS-certified install teams, principal contractor obligations under CDM 2015, full RAMS, scaffolding and access, and structured commissioning to BS EN 62446. Commissioning: witness testing with the DNO where required for G99 above 50 kW per phase, full electrical testing per BS 7671, structural sign-off from a chartered engineer, monitoring activation and customer training. Monitoring: 24/7 remote monitoring stack with automated alerts, customer portal access, and integration with your energy management systems if you have one. Maintenance: ongoing O&M contracts covering performance monitoring, annual inspection, warranty management, fault rectification and quarterly performance reporting. Every workstream is in-house or with carefully vetted long-term partners — never sub-contracted to whichever installer turns up cheapest on the day.

Sub-vertical breadth — where we specialise

Our project book over the past three years covers eight distinct commercial sub-verticals, each with their own load profile, financial-position pattern and operational sensitivities. Warehouses and distribution centres: large roof footprints, continuous lighting and MHE charging load, often 24/7 operation. Typical projects 250 kW–1 MW. Factories and manufacturing: single or multi-shift operations, CNC and processing load matched well to solar generation, frequent IETF eligibility on industrial decarbonisation. Typical projects 100 kW–750 kW. Hotels and hospitality: year-round demand, evening kitchen and laundry load creating battery storage opportunities, brand-level ESG drivers. Typical projects 50 kW–250 kW. Schools and academies: extended-day operation, ICT and catering load, Salix Finance funding eligibility, governor approval cycles requiring careful project management. Typical projects 50 kW–500 kW. Care homes and hospitals: 24/7 baseload, laundry and kitchen load, NHS Trust ESG mandates, infection-control sensitivity around install activity. Typical projects 50 kW–500 kW. Retail and supermarkets: continuous chiller load, lighting, public-facing premises requiring careful install scheduling. Typical projects 50 kW–500 kW. Light industrial and trade: single-shift operation, mid-size roof footprint, AIA-driven economics. Typical projects 50 kW–250 kW. Data centre support buildings: small relative to upstream centre but useful for building-side load and ESG reporting. Typical projects 100 kW–500 kW. See our sectors page for sub-vertical-specific guidance, case studies and load-profile details.

Geographic coverage

We operate UK-wide. Project teams are based in 12 regional centres so site response is fast, with engineers within 90 minutes of every commercial centre in England, Wales and Lowland Scotland. Concentration of recent project delivery: London and the South East (heavy commercial density), the Midlands (manufacturing and logistics), the North West (mixed industrial), Yorkshire and Humber (logistics, food processing), the South West (hospitality and rural), and Lowland Scotland (mixed). Northern Ireland projects we deliver through established install partners with whom we've worked for over five years. Cross-border DNO process for sites in Wales and Scotland is handled by the relevant licence area's DNO (Western Power Distribution, SP Energy Networks, Scottish Power Distribution) and we manage the application end-to-end. See our locations page for regional case studies and city-specific guidance covering Manchester, Birmingham, Bristol, Leeds, Sheffield, Liverpool, Newcastle and 23 other UK cities.

The four-step delivery process

Every project follows a consistent four-step process. Step 1: desk-based feasibility (5 working days). Send us your half-hourly meter data — usually a DCP228 export from your supplier portal. We pull a year of consumption, run a satellite roof model, check DNO heat-map for grid feasibility, run a draft PVSyst yield model and produce a feasibility report covering modelled yield, financial returns at three project sizes, grid connection feasibility, and headline assumptions. No charge, no obligation. Step 2: on-site survey (10 working days). If the desk feasibility numbers look worth pursuing, we visit. Survey covers structural assessment, electrical infrastructure mapping, asbestos register check, roof condition inspection, shading audit using Solmetric SunEye or drone-based 3D modelling, and discussions with site facilities teams. Half-day visit for sub-100 kW, full day for larger projects. Step 3: fixed-price proposal (7 working days after survey). Final proposal includes full PVSyst yield model, 25-year DCF financial model with sensitivity analysis, DNO connection feasibility narrative, full itemised pricing with no hidden contingencies, finance options compared (cash-with-AIA, asset finance, operating lease, PPA), and project programme. We share the underlying models — not just a marketing summary. Step 4: delivery. On contract signature, we file the DNO application within two weeks, run procurement and detailed design in parallel, and time site delivery to land immediately after offer acceptance. Single project manager, weekly progress updates, transparent issue log, structured handover. From contract to commissioning typically runs 8–24 weeks at sub-100 kW and 6–18 months at larger scales due to G99 timescales.

Trust signals — credentials that matter

Picking a commercial solar partner is a long-term decision. The asset will sit on your roof for 25 years and the relationships matter as much as the kit list. Five credentials we hold and renew on schedule. MCS: Microgeneration Certification Scheme certification for solar PV — required for G98/G99 grid connection and SEG export tariff eligibility. We hold full MCS PV certification and have done since the scheme's inception. NICEIC: registered electrical contractor under the National Inspection Council for Electrical Installation Contracting — covers all electrical work to BS 7671 standard. IWA: Institute of Workplace Advisors affiliation for renewables and energy efficiency advisory work. CHAS: Contractors Health and Safety Assessment Scheme accreditation — principal-contractor obligation under CDM 2015. SafeContractor: third-party H&S verification widely required by larger commercial clients and FM contractors. All certifications, renewal dates and accreditation numbers on our about page. We carry £10m public liability and £5m professional indemnity insurance. Independent auditing of our quality systems takes place annually.

Pricing transparency — what 2026 commercial solar actually costs

Three pricing bands cover all commercial solar in 2026. Sub-100 kW: £900–£1,200 per kW. So a 50 kW office or small retail unit at £45,000–£60,000 turnkey, a 75 kW factory unit at £67,500–£90,000. 100 kW–500 kW: £750–£950 per kW. So a 250 kW industrial unit at £190,000–£240,000, a 400 kW warehouse at £300,000–£380,000. Above 500 kW: £700–£850 per kW. So a 750 kW logistics campus at £530,000–£640,000, a 1 MW industrial park at £700,000–£850,000. AIA tax relief at 25% net main-rate corporation tax knocks the effective cost down by a quarter for any profitable limited company within the £1m AIA cap. Full pricing detail and per-sub-vertical ranges on the cost page. Grant funding (IETF for industrial, Salix for public sector, OZEV for paired EV charging) on the grants and funding page.

Typical questions before any project

Most enquiries come in with a similar set of questions and our FAQs page works through them in detail. Common ones: how much will my specific site save (modelled from your meter data, not estimated from a postcode); will my roof structurally support the install (chartered engineer survey); how long will the DNO take (varies — we check the heat-map up front); what happens during install on a working site (project planning, RAMS, day-by-day programme); how does the system perform in winter (UK winter generation runs 25–30% of summer peak; year-round economics still strong); what happens if a panel fails (warranty management included in O&M contract); can I monitor performance myself (24/7 portal access on every install); what if I sell the building (asset transfers cleanly with the property; PPA contracts have novation provisions). If your question isn't on the FAQs page, send an email — we respond within one working day on every enquiry.

Specific service offerings — system size, technology and finance

Within the broad commercial-solar category we run dedicated service pages covering the specific decision points clients face. System size guidance: 50 kW for offices, small retail and light industrial; 100 kW for hotels, schools and mid-format retail; 250 kW for warehouses, factories and large schools; 500 kW+ for industrial campuses, multi-building sites and ground-mount. Each page covers panel count, roof footprint, pricing, modelled savings, payback and grid-connection considerations specific to that scale. Technology add-ons: commercial battery storage for sites with strong evening or 24/7 baseload, and solar-integrated workplace EV charging for OZEV-grant-funded employee or public charging infrastructure. Finance routes: finance options comparison covering cash with AIA, asset finance, operating lease and PPA; dedicated PPA page for zero-capex routes; AIA page for the dominant tax relief on cash purchases. Ongoing service: commercial solar O&M contracts covering monitoring, annual inspection, warranty management and performance reporting through the asset's 25-year life.

What it costs to engage with us — and what we don't charge for

Five things we don't charge for: initial enquiry response (always within one working day), desk-based feasibility against your meter data (free, no obligation, returns within five working days on standard projects), on-site survey for projects we believe are worth pursuing (we don't charge for surveys; if the desk feasibility shows weak IRR we tell you up front rather than visit), fixed-price proposal preparation including PVSyst yield model and 25-year DCF (free, with the underlying models shared), and finance route comparison covering all four standard structures. We charge for delivery — install, project management, commissioning and ongoing O&M. The proposal pricing is fixed and locked at signature; we don't make money from change orders. Where genuinely unforeseen site conditions emerge during install (asbestos that wasn't on the management survey, structural issues hidden behind cladding, DNO reinforcement charges that didn't appear in the heat-map check), we agree the variation transparently with full evidence — never just push through change orders without consultation.
