Solar panel grants for Plastics & rubber processing

Extruders, injection moulders run high heat process load — combine PV with process electrification IETF case.

Grant stack for Plastics & rubber processing

Plastics & rubber processing businesses typically combine multiple funding routes for commercial solar projects:

• Tax relief: 100% Full Expensing (limited companies) or AIA (partnerships, sole traders)
• Export income: Smart Export Guarantee — 3p-15p/kWh on exported electricity
• Sector grants: See parent factories sector guide for the primary grant routes
• REGO sales (systems above 50kWp): additional 0.8-2p/kWh equivalent revenue
• Regional schemes: Growth hub grants, devolved nation funding — see locations hub

Plastics & rubber processing energy profile

FAQs

Plastics & rubber processing solar · FAQs

What solar grants apply to plastics and rubber processing in 2026?

Plastics & rubber processing businesses typically access the parent factories sector grant stack — see the factories sector guide for full details — plus sub-vertical-specific considerations covered below. The headline route depends on business structure (limited company, partnership, sole trader) and energy spend.

What size solar system suits plastics and rubber processing?

System sizing depends on annual electricity consumption and roof area. Plastics & rubber processing businesses typically operate at scales requiring 50-500kWp commercial PV. The cost & payback page covers each system size band.

What's the typical payback for plastics and rubber processing solar?

After 100% Full Expensing for limited companies, typical post-tax payback is 4-6 years for this sub-vertical. Strong self-consumption profiles compress payback further; export-led economics extend it.
