Grants, tax relief, and export tariffs in the UK, Sweden, and Scandinavia can fund 15–40% of a wind turbine installation. Eligibility varies by country, property type, income, and energy consumption. The best approach is a combination: secure a grant, claim tax relief if you are a business, and lock in a long-term export tariff.
Energy Company Obligation (ECO)
The ECO is the UK's main funding scheme for renewable installations on residential and commercial properties. Eligible homeowners, tenants, and small businesses can receive grants of £5,000–£15,000 towards the cost of a wind turbine, solar installation, or battery storage. Eligibility is means-tested in some cases.
Visit Energy Company Obligation on GOV.UK to check if you qualify. Most applications are fast-tracked — expect a decision within 4–8 weeks.
Local authority grants
Many local authorities offer top-up funding for renewables on top of ECO. Search your local council website for "renewable energy grants" or contact your planning department. Funding varies (£1,000–£10,000) and may require you to demonstrate energy efficiency first (insulation, heating upgrades).
Business investment allowances
If you are a registered business, renewable energy equipment qualifies for capital allowances under UK tax law. You can claim the full installation cost as a business expense, offsetting it against taxable profits. This is not a grant but a deduction that reduces your tax bill.
Consult your accountant or a tax adviser to claim this. The saving is substantial (19–25% of cost) if your business is profitable.
Enhanced Capital Allowance
Renewable energy installations may qualify for Enhanced Capital Allowance (ECA), allowing 100% first-year depreciation for tax purposes. This is available to businesses that claim Corporation Tax or Income Tax. Again, consult your tax adviser to confirm eligibility.
Feed-in Tariff (FIT) — legacy scheme
The Government's Feed-in Tariff scheme (closed to new applicants in March 2019) guaranteed payment for renewable electricity for 20 years. Existing FIT holders continue to receive payments. If you installed before the closure, check your tariff — it may be higher than current market rates.
Smart Export Guarantee (SEG)
All UK electricity suppliers must offer a tariff for renewable electricity exported to the grid. Rates typically range 15–25 p/kWh, depending on supplier and contract length. The tariff is not a grant but a long-term revenue stream. A WindWhisperer 100 Max exporting 50 MWh per year at 20 p/kWh generates £10,000 annual revenue.

Renewable Energy Certificates (REC) System
Sweden and Norway operate a joint REC system. Renewable generators receive Tradeable Green Certificates for every megawatt-hour produced. The certificates are sold on the market at a floating price (typically €20–50/MWh). Revenue from certificates supplements the grid export price.
For a Swedish wind turbine, REC income is significant. A WindWhisperer 100 Max generating 230 MWh annually at €30/certificate earns roughly €6,900 annually from RECs alone.
Regional and municipal grants
Some Swedish regions (Västra Götaland, Öland, and others) offer grants for small-scale wind installations, particularly on farms or in rural areas. These are typically €2,000–€5,000. Contact your regional energy agency or municipality for details.
Tax deductions
Businesses can deduct renewable equipment costs from taxable income. Self-employed farm owners can often claim accelerated depreciation. Consult your accountant or a Swedish tax adviser for site-specific guidance.
Electricity tax rebate
If you are a business or farm with a wind installation, you may qualify for a rebate on grid electricity purchases. The rebate reduces your overall electricity costs even if you export surplus power. Details vary by region — contact your local tax office.
Denmark — Net-metering and support schemes
Small-scale wind turbines in Denmark can be net-metered (run backwards on the grid if you produce more than you consume). Denmark does not have a direct grant scheme, but the net-metering rule provides a de facto subsidy by allowing you to "bank" surplus generation against future consumption.
Norway — Renewable energy agreements
Norway offers renewable energy certificates and support schemes for small hydropower, but wind turbines are less common. Some municipalities offer grants. Check with your local energy authority.
Finland — Investment support
Finland's Business Finland programme offers investment support for renewable energy projects on farms and businesses. Grants typically cover 30–40% of project cost for eligible rural sites.
1. Apply early — Many schemes have annual budgets that deplete quickly. Submit applications in January–February for the best chance of funding.
2. Get quotes first — Grants are usually paid after installation is complete and verified. Some (like ECO) may provide advance payments. You need a formal quote from an installer to trigger most applications.
3. Combine schemes — You can stack an ECO grant, a local council top-up, tax relief, and a SEG tariff. Each addresses a different cost component. Work with your installer or a renewable energy adviser to identify all applicable schemes.
4. Document everything — Keep invoices, quotations, grant approval letters, and installation photographs. You may need to provide evidence to claim tax relief or for future grant applications.
5. Update your energy performance certificate (EPC) — After installation, update your property's EPC. This unlocks some grants and improves property value.
