What independent solar project management delivers
UK commercial solar projects above £250k capex have three things in common: complex scope, multiple stakeholders, and substantial financial exposure. Independent project management protects the asset owner across all three. The PM acts as the owner's representative — separating the commercial interests of the EPC contractor (whose margin grows with scope) from the project decisions (which should optimise long-term asset value).
For ground-mount projects above 1 MW or rooftop installs above 500 kW, the typical pattern: independent PM saves 5–10% of total capex through EPC tendering discipline, prevents 3–8% of scope creep through change-order management, and resolves 2–4 critical issues during commissioning that would otherwise cost £20k–£200k in retrofit. Net result: PM fee of 2–5% capex returns 8–17% capex equivalent.
The seven-stage project structure we use
We structure UK solar farm projects against the RIBA Plan of Work 2020:
- Feasibility (RIBA 0–1): Half-hourly meter data analysis, indicative sizing, financial model. Free of charge.
- Concept design (RIBA 2): System architecture, single-line diagram, indicative module and inverter specification.
- Planning and G99 submission (RIBA 3): Permitted Development or planning consent, DNO grid connection application.
- Technical design and EPC tender (RIBA 4): Issue-for-construction package, EPC tender, contractor selection.
- Construction (RIBA 5): On-site install with daily monitoring and snag tracking.
- Commissioning and handover (RIBA 6): G99 commissioning, MCS, monitoring portal.
- Operations and monitoring (RIBA 7): Ongoing remote monitoring, warranty claim management.
Stakeholder coordination
UK farm solar projects routinely involve multiple stakeholders: the asset owner (farmer or family trust), tenant farmer (where applicable), landlord agent (for tenanted estates — Crown Estate, Duchy of Cornwall, Church Commissioners, Bedford, Buccleuch, Devonshire, NFU Mutual, Wellcome Trust), DNO (NGED, SSEN, SP Energy Networks, Northern Powergrid, UK Power Networks, Electricity North West), planning authority, EPC contractor, equipment manufacturers, finance provider (asset finance / PPA / capital), and end-customer (supermarket supplier audit teams). Independent PM coordinates all of these so the asset owner doesn't have to.

How to get started
For projects above £250k capex, book a free 30-minute PM scoping call. We'll review your project brief, indicative timeline, and the stakeholder mix; you'll get a clear view of whether independent PM is right for your project and what scope of services makes sense. No commitment.
UK solar farm project management — common questions
What does a solar farm project manager actually do?
A solar farm project manager owns the delivery programme end-to-end on behalf of the asset owner — coordinating design, planning, DNO grid connection, procurement, EPC contractor selection, construction monitoring, commissioning, and handover. The PM acts as the owner-side advocate, separating the commercial interests of the EPC contractor from the project decisions. For ground-mount and large rooftop projects above £500k capex, an independent PM typically saves 5–10% of total capex through better EPC tendering, scope-creep prevention, and DNO works negotiation.
When do I need an independent solar project manager?
For any UK solar project above £250k capex (typically 250 kW+ rooftop or 1 MW+ ground-mount), an independent PM pays for itself in EPC margin saved and risk-reduction. For projects below £250k, the EPC contractor typically self-manages. The exception: projects involving multiple stakeholders (landlord plus tenant farmer plus supermarket supplier plus financier) where independent coordination is essential regardless of project size.
How is solar farm project management priced?
UK independent solar PM is typically priced as 2–5% of total project capex. For a £1m project, expect £20,000–£50,000 PM fee. Discount the PM cost against the EPC margin saved (typically 5–10%) and the value of avoided scope creep — independent PM is consistently capex-positive on projects above £500k. Some PMs offer fixed-fee structures aligned to RIBA project stages.
What's the RIBA Plan of Work for a solar project?
UK solar projects can be structured against the RIBA Plan of Work 2020: Stage 0 (Strategic Definition — feasibility), Stage 1 (Preparation and Briefing — desk study, half-hourly meter analysis), Stage 2 (Concept Design — system architecture, single-line diagram), Stage 3 (Spatial Coordination — PVSyst modelling, structural design, DNO G99 submission), Stage 4 (Technical Design — issue-for-construction package), Stage 5 (Manufacturing and Construction — install), Stage 6 (Handover — commissioning, MCS), Stage 7 (Use — O&M handover). Independent PMs typically own stages 1–7 on the owner side.
Can I project-manage my own solar install?
For projects below £150k, owner self-PM is feasible and common. Above that capex, the time cost of self-PM (typically 40–80 working hours through delivery) plus the risk of scope creep, EPC mark-up, and DNO mis-handling usually outweigh the saved fee. Family farms with strong technical and commercial capability sometimes self-PM up to £500k; corporate farm operations almost always use independent PM above £250k. We provide a free PM scoping call — talk to us about your project before deciding.
What's the timeline for a UK commercial solar project?
Indicative timelines from contract to commissioning: 250–500 kW rooftop 4–7 months; 500 kW–1 MW rooftop or ground-mount 7–12 months; 1–5 MW ground-mount 12–18 months; 5 MW+ utility-scale ground-mount 18–30 months. The binding constraint is almost always DNO G99 grid connection, particularly on capacity-constrained rural feeders. We submit G99 applications immediately after concept design completion to compress total timeline.
