Free solar carport UK: scam or real offer 2026?

“Free solar carport funded by government grant!” “Solar panels for £1 with ECO4!” “Self-funding install, you pay nothing!” These messages, omnipresent on Facebook, Instagram and TikTok since 2023, attract thousands of UK homeowners each week. The majority end up with hidden debt, owning an installation of dubious quality, sometimes with no valid insurance in case of failure.

Trading Standards UK received over 5,400 complaints in the solar PV sector in 2025, a third with losses above £10,000. This article — with no sponsored content — explains what is actually behind “free” solar carport offers, identifies the 7 most common pitfalls, and details the real grants and incentives that can deliver a near-zero net investment over the long term.

The economic truth: a solar carport CAN NOT be free

A solar carport for 2 cars with 16 panels of 400 Wp (6.4 kWp) costs at real material + manufacturing + installation:

Bespoke metal structure to BS EN 1991: £5,800 - £9,800 ex VAT
16 modern solar panels 400 Wp: £3,400 - £4,700 ex VAT
Hybrid inverter + protection: £1,100 - £2,500 ex VAT
Cabling, consumer unit, DNO connection: £1,400 - £2,300 ex VAT
MCS-certified installer labour: £1,900 - £4,200 ex VAT
Target total: £13,600 - £23,500 ex VAT

No company can give this sum away. „Free” offers always hide an economic counterpart.

The 7 pitfalls of „free” offers

Pitfall 1 — Hidden consumer credit

Dominant scam in 2026. The script:

Cold call or doorstep visit. „£0 thanks to ECO4 grant + 0% VAT”. You sign a „reservation document”. Days later, a consumer credit agreement over 20 years at 7-9% APR is presented, hiding a total cost of £28,000-£45,000 for a real £14,000 installation.

How to spot it: any mention of „monthly payment”, „finance partner”, „APR”, „credit” → not free.

Pitfall 2 — Inflated ECO4 funding

ECO4 (Energy Company Obligation 4) is a real UK scheme but does not directly fund solar PV for most households. It funds insulation and heating for low-income or vulnerable households (LIHC criterion). Some bundles include PV but only for very specific eligibility (typically households on certain benefits with low EPC ratings).

Reality 2026:

ECO4 PV is rare and tightly means-tested
Average grant if eligible: £2,000-£8,000 for combined measures
Not £15,000 for solar alone as some scammers claim

How to spot it: ask for the official ECO4 funding letter from the obligated supplier. Verify on Ofgem ECO scheme page.

Pitfall 3 — The rent-a-roof deception

Rent-a-roof scheme: a company installs panels on your roof/carport, you remain owner of the structure, the company collects feed-in revenue or SEG payments for 20 years. At end, you own the panels.

Legal but with traps:

Lease must be registered at HM Land Registry (legal charge)
You give up 20 years of energy income
Maintenance and insurance often shifted to you
If the company goes bust (common post-2022 after FiT ended), you own aging panels with no maintenance contract

How to evaluate: insist on registered lease, independent insurance-backed buyback guarantee, financial check (Companies House filing history showing > 5 years filed accounts with positive equity).

Pitfall 4 — Bogus „government grant” claims

Some sellers invent „government solar grant of £6,000” to justify free claims. No general UK solar grant exists for homeowners in 2026. Real schemes:

0% VAT on installation (April 2022 — now permanent): meaningful saving (~£2,500 on £15,000 install), not a „grant”
Smart Export Guarantee (SEG): small income for exported electricity (1-15p/kWh depending on supplier), not a grant
ECO4: only for eligible low-income households (above)
Home Upgrade Grant (HUG): rural off-gas low-income only, very narrow

No „£6,000 universal solar grant” exists in the UK.

How to spot it: ask for the scheme reference and government source URL. Check gov.uk for any cited scheme.

Pitfall 5 — Non-MCS-certified installer

For SEG export tariffs and 0% VAT relief, the installer must hold MCS certification (Microgeneration Certification Scheme). Without it:

No SEG eligibility (lose £100-£300/year over 20 years)
20% VAT applies instead of 0% (~£2,500 extra cost)
Buildings insurance can refuse claims

How to spot it: ask for MCS installer certificate. Verify on mcscertified.com.

Pitfall 6 — Hollow „25-year warranty”

„25-year warranty” is heavily used. But who guarantees what?

Performance warranty (panels): 80% output at 25 years (manufacturer standard)
Product warranty (panels): 12 years typical, 20-25 years premium
Workmanship warranty (installer): 6 years under MCS, 2 years RECC scheme
Structure warranty (carport): variable, often only 2 years from „free installers”

A „25-year warranty” without specifying what and by whom is legally hollow. The company may be gone in 5 years.

Pitfall 7 — Shell company carousel

You sign with „Solar Eco UK Ltd”. Three months later „Eco Solar Pro Ltd” installs. Six months later, „Energy Solar 2026 Ltd” services it — with no contractual link to your file. „Free solar” companies cycle shell entities to avoid long-term obligations and litigation.

How to spot it: check Companies House that the contracting company exists > 5 years, has positive net assets > £100,000, and an identifiable director with no pattern of dissolved companies.

The real grants and incentives that can deliver net £0

Over 20-25 years, a well-designed PV installation can self-fund through:

1. 0% VAT on installation

Since April 2022 (permanent since 2024 Spring Budget): zero VAT on qualifying energy-saving materials including solar PV and the supporting structure. Saves ~£2,500-£4,000 on a typical install.

2. Smart Export Guarantee (SEG)

Real export tariff from licensed suppliers. Best 2026 rates:

Octopus Outgoing Fixed: 15p/kWh (one of highest)
E.ON Next Export: 16.5p/kWh
British Gas Export & Earn Plus: 15p/kWh
Octopus Outgoing Agile: variable, average 12-25p/kWh

For 6 kWp with 30% export: ~£200-£400/year SEG income.

3. Self-consumption savings

UK electricity tariff ~28-32p/kWh (2026 average). With 70% self-consumption on 6 kWp producing 5,500 kWh/year (UK average): £1,080-£1,230/year saved = £21,600-£24,600 over 20 years.

4. Battery storage incentives

EV/Battery tariff bundles (Octopus Intelligent, EDF GoElectric) can save additional £200-£500/year on top of standard self-consumption.

Real economic balance

For a Sunrak solar carport 2 cars 6 kWp in Manchester:

Item	Amount
Initial investment (structure + panels + install)	-£14,500
0% VAT saving (vs 20%)	+£2,900
SEG income 20 years	+£6,000
Self-consumption savings 20 years	+£23,000
Maintenance (10 cleanings)	-£600
Net balance 20 years	+£16,800

Conclusion: net positive balance over 20 years, without fictitious grants. The structure (aluminium 40+ years, panels 25-30 years) continues producing pure margin beyond year 20.

FAQ — Free solar carport UK scams and real incentives

Do £1 solar panels really exist in the UK?

Not for typical homeowners. £1 solar offers usually mask consumer credit or rent-a-roof schemes that surrender 20-25 years of energy savings. Any cold-called „£1 solar" offer is a scam vehicle.

Can my installation really net £0?

Over 20-25 years, yes, thanks to 0% VAT + SEG + self-consumption savings. But with a real initial investment of £10,000-£20,000. Instant zero cost does not exist legitimately.

Real grants available in 2026?

Mainly 0% VAT (universal) and SEG (paid by your electricity supplier). ECO4 is means-tested for low-income households. HUG is off-gas rural low-income. No universal solar grant exists for the average UK homeowner.

What if I'm a solar scam victim?

Three steps: (1) Report to Trading Standards via 0808 223 1133 (Citizens Advice consumer helpline), (2) Report to RECC (Renewable Energy Consumer Code) for MCS-related complaints, (3) Solicitor for breach of contract or misrepresentation. Consumer Rights Act 2015 protects you.

Is rent-a-roof viable?

Theoretically yes, with caution: registered lease, financial checks on the operator, weigh 20-year revenue loss. For homeowners, self-consumption is generally more rewarding than rent-a-roof.

Does ECO4 cover solar PV?

Rarely. ECO4 primarily funds insulation and heating for low-income (LIHC) households. Solar PV is occasionally part of bundles but tightly means-tested. „Free solar via ECO4" is misleading marketing in 95% of cases.

Does Sunrak offer „free carports"?

No. We sell bespoke BS EN 1991-engineered structures at transparent prices. No cold calling, no „miracle offers". Our promise: a structure that lasts 40 years, sold at fair price with full structural calculation included.

What is the cooling-off period?

14 calendar days for distance and doorstep sales (Consumer Contracts Regulations 2013). For in-store sales: no statutory cooling-off. Read the contract carefully before signing.
