The net zero economy is no longer a niche — it is one of the fastest-growing parts of the UK economy, and the installer trades sit at the centre of it. That growth brings record demand, but also rising scrutiny from certification bodies, the HSE and insurers. Specialist cover is now a competitive necessity, not an afterthought.
One pillar, every green-tech trade — pick your specialism
Renewables firms rarely stay in one lane. A solar installer adds battery storage; a heating engineer moves into heat pumps; an electrician starts fitting EV chargers. Each technology carries its own underwriting profile, and each must be declared explicitly. Below are the trade-specific routes — start with yours, or get a single schedule covering all your activities.
☀️ Solar Panel Installers
MCS & RECC-compliant cover, working-at-height scope, faulty workmanship and BESS lithium battery scope for solar PV contractors.
🔥 Heat Pump Installers
F-Gas / refrigerant liability, MCS heat pump design and sizing, escape-of-water and electrical works cover for ASHP & GSHP installers.
🔌 EV Charge Point Installers
Electrical isolation and product liability, OZEV grant documentation, Part P and load-assessment design cover for EV charger installers.
🔋 Battery Storage (BESS) Installers
Lithium fire and thermal-runaway scope, BS 7671 Section 712 compliance, environmental impairment and battery-sizing PI for storage specialists.
MCS certification — the framework that shapes your insurance
The Microgeneration Certification Scheme (MCS) is the UK quality-assurance standard covering solar PV, battery storage, heat pumps, biomass and wind. It is the gateway to the Boiler Upgrade Scheme and the Smart Export Guarantee — which means, for most customers, it is the gateway to getting hired. Several MCS requirements feed directly into how your policy is underwritten.
Public Liability £2m+ (£5m for some certification bodies)
The headline insurance requirement. Underwriters now expect MCS minimums at proposal across every renewable technology.
Professional Indemnity
Required by most certification bodies — covers design errors, sizing and heat-loss miscalculations, and yield or consumption disputes.
Nominated Technical Person & technology training
A named person must hold the relevant MCS-approved training for each technology. Changes affect underwriting and disclosure.
Consumer Code membership (RECC, HIES or GGF)
A CTSI-approved code is mandatory, and the requirement to issue insurance-backed guarantees interacts with your PI and Contract Works cover.
Quality Management System (QMS)
Documented installation processes. Underwriters frequently ask for QMS evidence at proposal for MCS firms.
Technology-specific competence
Part P for electrical works, F-Gas for refrigerants, BS 7671 Section 712 for storage — each affects scope and pricing.
The core exposures across the renewable trades
Whatever you install, four exposures dominate the claims experience — and they are exactly the areas generic tradesman cover handles worst.
Working at height
Roof-mounted solar and many heat pump and battery installs put operatives at elevation. Falls are the highest-severity EL exposure, with strict duties under the Work at Height Regulations 2005.
Fire & thermal runaway
Lithium battery storage and EV charger faults carry fire and thermal-runaway risk. Many policies exclude or sub-limit lithium work unless it is explicitly declared and underwritten.
Faulty workmanship
Roof leaks after solar fixing, escape of water on heat pump wet systems, inverter and connection failures — the most common customer complaints, and routinely excluded from generic PL.
Design & advice liability
Sizing errors, over-optimistic yield or heat-loss estimates, and grant application mistakes trigger Professional Indemnity claims even when the physical install is faultless.
What renewable energy installer insurance covers
A modular package, built around the actual exposures of the green-tech trades. The right structure depends on which technologies you install and at what scale.
Public Liability £2m–£10m
MCS minimum £2m (some bodies £5m); £5m–£10m for commercial and grid-tied work. Customer property damage scope is critical.
Employers' Liability £10m
Legally required for staff, apprentices and labour-only subcontractors. Falls-from-height occupational scope is essential.
Professional Indemnity
£250k–£2m+ for design errors, sizing and heat-loss miscalculations, yield disputes and grant-scheme application errors.
Faulty Workmanship
Damage arising from your installation work — roof leaks, escape of water, inverter failures, wiring fire risk.
BESS Lithium Battery Scope
Specialist cover for storage installation — lithium fire, thermal runaway and BS 7671 Section 712 compliance.
F-Gas / Refrigerant Liability
Heat pump refrigerant handling exposure, F-Gas competence and associated environmental scope.
Contract Works (CAR)
Installation works in progress — panels, inverters, batteries and heat pump stock at the customer's property.
Tools, Plant & Vehicles
Vans, scaffolding, MEWPs, harnesses, inverters, test and diagnostic equipment at full replacement value.
Legal Expenses (HSE scope)
HSE investigation defence, MCS and consumer-code dispute resolution, RECC complaints, contract disputes.

Real World Example
A multi-trade renewables firm approached Miller & Partner after expanding from solar PV into battery storage without updating their schedule. When a lithium battery installation was alleged to have caused a fire and property damage, their original solar-only policy did not contemplate BESS work. We reviewed the exposure, placed a corrected schedule with explicit lithium and thermal-runaway scope through a specialist renewables market, and worked with insurers to manage the position — restoring the cover the business needed to keep trading and bid for storage contracts with confidence.
Our expertise in this field
At Miller & Partner, we arrange tailored insurance for the businesses building the UK's net zero transition — solar PV, heat pump, EV charging and battery storage installers, from sole traders to multi-trade regional firms. We understand the exposures that define these trades: working at height, lithium fire, refrigerant handling, design liability and the MCS and consumer-code framework that underpins them. With access to leading UK insurers and the Lloyd's market, and a hands-on, no-pressure approach, we make sure the right cover is in place from proposal through to claim.
