Can I Install Solar Panels Myself?

Posted May 16, 2025

With rising energy bills and a national push towards decarbonisation, solar panels are increasingly seen as a smart, future-proof investment. Yet many UK property owners are asking: “Can I install solar panels myself?”

Whether you’re a homeowner looking to cut costs, a landlord aiming to improve your EPC rating, or a commercial property owner seeking sustainability gains, understanding the realities of DIY solar installation is vital. This guide explores the legal, financial, and technical aspects of self-installing solar panels in the UK—and whether it’s truly worth it.

Can I Legally Install Solar Panels Myself in the UK?

In the UK, installing solar panels involves more than just screwing panels onto a roof. While there are no laws outright banning DIY solar panel installation, several key regulations and certifications must be adhered to, especially if you plan to sell energy back to the grid or improve your home’s Energy Performance Certificate (EPC).

What Are the Legal Requirements for Solar Panel Installation?

UK regulations make solar installation a controlled process. If you’re not a certified professional, you may still carry out the installation yourself, but you’ll need to notify your local council, comply with Part P of the Building Regulations, and likely arrange for an inspection—often at your own expense.

Moreover, without using an MCS-accredited installer, you won’t qualify for financial schemes like the Smart Export Guarantee (SEG), meaning you’ll miss out on potential income from selling unused electricity.

Are There Consequences of Not Following the Rules?

The short answer is: yes, and they can be serious. Besides potential fines and enforcement actions, improperly installed solar systems can affect:

Insurance coverage
Resale value
Safety compliance
Eligibility for green energy incentives

This is why even those with DIY experience often opt to at least involve a professional for system sign-off.

What Are the Pros and Cons of Installing Solar Panels Yourself?

Installing solar panels yourself can seem attractive, especially for those wanting to reduce labour costs. However, DIY solar comes with considerable trade-offs—many of which aren’t immediately obvious until after the system is installed.

What Are the Potential Benefits of DIY Solar Installation?

On paper, self-installation offers notable perks:

Labour Savings: You could cut installation costs by up to 40%.
Scheduling Freedom: Work at your own pace without waiting on an installer.
Educational Value: Gain hands-on knowledge of your own renewable energy system.

That said, these advantages may be outweighed by efficiency losses, missed incentives, or mistakes that require costly rework.

What Are the Risks and Challenges?

DIY solar installation often involves:

Roof Work Hazards: Safety is a real concern when working at heights.
Electrical Dangers: Improper wiring can be dangerous and is a fire risk.
Regulatory Non-Compliance: Uncertified systems disqualify you from SEG payments and may breach building regulations.
System Inefficiency: Without expert design, your system may underperform—delaying ROI.

Is DIY Solar Worth It for Homeowners, Landlords, or Businesses?

The value of DIY solar differs based on who you are and your energy goals. Below, we break down considerations for key groups: homeowners, landlords, and commercial property owners based in the North East of England.

Homeowners: Is It a Viable DIY Project?

For tech-savvy homeowners with some electrical experience, a DIY solar kit might look like a cost-saving shortcut. However, unless you’re a certified electrician, you’ll still need a professional to inspect and approve the system—especially if you want to connect it to the grid.

Moreover, homes with uncertified solar systems may struggle with:

Lower resale appeal
Ineligibility for government-backed incentives
Limited EPC improvements

Landlords: What Should You Consider?

For landlords, compliance isn’t optional. DIY installations could put you in violation of:

Housing Health and Safety Rating System (HHSRS)
EPC minimum ratings for lettings (Band C from 2025)

A certified system enhances property value and tenant satisfaction—two key priorities for any landlord.

To avoid project delays and maximise generation, learn the best time to install solar panels in the UK, particularly helpful for landlords planning upgrades between tenancies.

Commercial Property Owners: What Are the Stakes?

Commercial installations are typically much larger and require careful engineering and coordination with Distribution Network Operators (DNOs) for grid compliance. Attempting a DIY approach at this scale is not only impractical but potentially damaging to business continuity.

Professional installation ensures:

Compliance with G99/G100 connection standards
Access to capital allowances and energy grants
Long-term performance monitoring and maintenance

What Are the Alternatives to DIY Solar Installation?

If you’re keen to reduce costs but hesitant about full DIY, there are middle-ground options that preserve safety and compliance.

Can You Do Part of It Yourself and Still Qualify for Benefits?

Yes. Many UK homeowners opt to:

Handle panel mounting themselves
Hire a certified electrician for wiring and final approval

This hybrid method can lower costs while still enabling eligibility for SEG payments and ensuring warranty coverage remains intact.

How Much Does Professional Solar Installation Cost in the UK?

As of 2025, UK costs for solar installations are competitive:

3kW system (suitable for small homes): £5,000–£7,000
4kW–6kW system (larger homes): £6,000–£10,000

Labour typically accounts for 20–30% of this cost—money you might save with a partial DIY, though not without risks.

Are There Government Grants or Schemes for Solar in 2025?

To encourage solar uptake, the UK government continues to offer schemes that make solar more affordable—especially for lower-income households and green-conscious landlords.

What Help Is Available for Homeowners and Landlords?

ECO4 Scheme: Grants for solar panels and insulation for qualifying households
Smart Export Guarantee (SEG): Earn money for exporting surplus energy—only with MCS-certified systems
0% VAT on Solar Panels: Available on domestic installations until 2027

These incentives significantly improve solar ROI—but only if you use accredited professionals.

Commercial Grants and Incentives

Businesses can access:

First-year Capital Allowances: Write off full costs of solar installations against taxable profits
Renewable Heat Incentive (RHI): For solar thermal systems
Green Business Grants: Offered by some local councils and LEPs

What Should I Look for in a Professional Installer?

If you decide to forgo the DIY route, choosing the right installer is crucial. A professional not only handles the technical side but also ensures your system is compliant, efficient, and eligible for all available incentives.

How to Choose a Reputable Solar Company

Here’s what to look for:

MCS Certification: A non-negotiable if you want SEG payments
Customer Reviews: Check Google, Trustpilot, and Checkatrade
Clear Warranties: Look for panel and inverter guarantees of at least 10 years
Aftercare & Monitoring: Some installers offer apps or portals to monitor system performance

Still unsure who to hire? Learn how to choose a solar panel installer that meets UK standards and offers long-term reliability, such as Future Heat, for homes & commercial properties in Newcastle and the North East.

Frequently Asked Questions (FAQs)

Usually not. Most homes fall under permitted development, but listed buildings or conservation areas may require approval. Check with your local council.

Yes, but it’s more complex. You’ll need angled mounts and ballast. Professional help is advised to ensure safety and performance.

Yes, but most kits aren’t MCS-certified, so they won’t qualify for SEG payments or grid connection. Best for off-grid use only.

Insurance may not cover damage, and warranties could be void. Faulty installs can also pose fire or electrical risks.

Yes, but it depends on system compatibility. Grid-tied batteries usually require professional installation and approval.

Our Verdict

While installing solar panels yourself might initially seem like a cost-saving shortcut, the reality in the UK is more complex. Regulatory hurdles, safety concerns, and the loss of financial incentives often outweigh any upfront savings—particularly for homeowners, landlords, and commercial property owners looking for a reliable return on investment.

For most property owners, the smartest approach is to partner with a certified professional. This ensures your system is compliant with UK laws, eligible for the Smart Export Guarantee, and protected by long-term warranties.
