Remove the Capital Barrier to Solar
The most common objection we hear is not about solar technology — it is about cash flow. Most UK businesses cannot justify a large capital outlay, even when the payback is compelling. That is why Bee Solar offers multiple pathways to go solar with minimal or zero upfront cost.
Whether you want to preserve capital through a PPA, spread the cost via hire purchase, or access low-rate green loans, we guide you to the option that aligns with your financial strategy.
Four Ways to Fund Your Solar Project
Each option suits a different financial profile. Compare them below or speak to our team for a personalised recommendation.
Power Purchase Agreement (PPA)
Zero upfront cost. Immediate savings.
Best for: Businesses with strong credit and long-term site occupancy
How It Works
- 1A specialist investor funds and owns the solar system on your roof.
- 2You purchase the electricity generated at a fixed rate 20–40% below grid prices.
- 3No upfront capital cost, no ongoing maintenance responsibility.
- 4At contract end (typically 15–25 years), you can buy the system for fair market value or extend the agreement.
Real-World Example
Pros
- £0 capital expenditure
- Immediate electricity bill reduction
- No maintenance or performance risk
- Fixed, predictable energy costs
- No asset depreciation on your balance sheet
Considerations
- Long-term contract commitment (15–25 years)
- Investor retains tax benefits
- Site lease may be required
- Buy-out cost at end of term

Grants, Tariffs & Tax Reliefs
On top of financing, several UK government programmes can reduce your net cost or generate ongoing income from your solar installation.
Annual Investment Allowance (AIA)
Up to £1M per year
Claim 100% of your solar system cost against taxable profits in the year of purchase. For most commercial solar systems, this means the full installation cost is deductible immediately.
Smart Export Guarantee (SEG)
1p – 20p per kWh
Sell surplus solar electricity back to the grid through your energy supplier. Major suppliers including Octopus, E.ON, and British Gas offer competitive SEG tariffs.
Full Expensing (Capital Allowances)
100% first-year deduction
From April 2023, businesses can deduct the full cost of qualifying plant and machinery — including solar panels — from profits before tax in the year of purchase.
Rural England Prosperity Fund
Up to £100,000
Rural businesses in eligible Local Authority areas can apply for capital grants covering up to 40% of solar installation costs. Managed through your local council.
Salix Finance (Public Sector)
Up to £multi-million
Public sector organisations including NHS, schools, and local authorities can access interest-free government loans for energy efficiency and renewable projects.
Low Carbon Workspaces (Regional)
Up to £5,000–£50,000
Several Local Enterprise Partnerships (LEPs) offer capital grants for SMEs investing in low-carbon technologies. Availability varies by region.
Financing for Hospitality & Heritage Properties
Hotels, pubs, and holiday parks face unique funding challenges: listed building constraints, seasonal cash flow, and the need to preserve character. These are the structures we use most.
Heritage-Friendly PPA
Zero upfront. Zero visual impact. Full planning support included.
Best for: Grade II listed hotels, country inns, and spas with conservation officer requirements
How It Works
- 1Investor funds and owns the system on rear roofs or outbuildings only.
- 2Full heritage impact assessment and conservation officer liaison included.
- 3All-black panels on dark frames with sympathetic materials.
- 4No visible panels from public approach or guest viewpoints.
- 515–20 year term with buy-out at fair market value.
Real-World Example
Pros
- £0 capital cost
- Full planning and heritage support included
- No maintenance or performance risk
- Fixed electricity rates 25–35% below grid
- Preserves building character and listing status
Heritage properties cannot risk capital on unproven technology. A PPA transfers all performance and planning risk to the investor while the hotel enjoys immediate bill savings and preserved character.
Grants and Reliefs for Listed & Rural Hospitality
On top of standard business financing, these programmes specifically support solar on listed buildings and rural hospitality businesses.
Historic England offers capital grants for energy efficiency improvements to listed buildings, including discrete renewable energy installations that preserve architectural character.
Grade I, II*, and II listed buildings in England
Rolling — apply via your regional Historic England office
Some local authorities waive or reduce listed building consent application fees for renewable energy proposals that demonstrate clear carbon reduction benefits. Bee Solar prepares the full application to qualify.
All listed building solar applications
Varies by local authority
Rural pubs, hotels, and restaurants in designated areas can access capital grants for building improvements that reduce operating costs and support year-round viability — solar qualifies when framed as cost reduction.
Rural hospitality businesses in designated revitalisation zones
Check your local council for current windows
Solar panels installed on any commercial building — including listed properties with consent — qualify for full expensing. For a £120k system, this means £33,600 in effective tax relief at current corporation tax rates.
All UK companies with qualifying plant and machinery
Permanent from April 2023
