Why Preston businesses are installing solar in 2026
Commercial electricity prices for Preston businesses have risen 35-50% since 2022 with no sign of returning to pre-2021 levels. For a typical Preston SME with £30,000-£60,000 annual electricity spend, that translates to £10,000-£20,000 per year of preventable cost — money that could be sitting on the balance sheet instead.
We install commercial solar PV across Preston and the wider Lancashire area: rooftop systems on warehouses, factories, offices, and retail; ground-mounted arrays where space allows; solar carports over staff parking. 160++ local installs completed, MCS commercial certified, with direct relationships with Lancashire planning departments for any Conservation Area or listed-building heritage work.
The financial case is now compounded: 100% Annual Investment Allowance (AIA) gives full corporation tax relief in year 1 on capital costs up to £1m. Smart Export Guarantee (SEG) earns £400-£900 per year on a typical 100 kWp install. Power Purchase Agreements (PPAs) offer £0 upfront with 20-25% energy savings from day one. Payback runs 6-8 years self-funded, dropping to 4.5-6 years after AIA tax relief.

Three ways to fund commercial solar in Preston
Option 1 · Self-Funded + AIA
100% Annual Investment Allowance
Buy outright. Claim 100% AIA in year 1 — full corporation tax relief on the capital cost up to £1 million. On a £100,000 install at 25% corporation tax, that's £25,000 back in year 1.
Effective payback: 4.5-6 years
Option 2 · Asset Finance
Solar Asset Finance
Spread the cost over 5-10 years against the AIA tax shield. Monthly payments lower than your energy savings from day one — solar pays for itself while the loan amortises. Available from £30k upwards.
Cashflow positive from month 1
Option 3 · PPA
Power Purchase Agreement
£0 upfront. We install, own, and maintain the system; you buy the solar electricity at a fixed rate ~25% below your grid tariff. 20-25 year term, no escalation. Available for sites with £15k+ annual electricity spend.
Day-1 energy savings, zero capital outlay
