Professional installation costs 3 to 5 times more than a DIY garden solar lights install
Installing garden solar lights yourself is significantly cheaper than hiring a professional. The difference in upfront cost is the most important factor for most homeowners considering this project.
DIY garden solar lights cost £80-£200, compared to £400-£800 for professional installation. You save 60-70% by eliminating labour costs, but DIY lights output 80-150 lumens and last 2-4 years versus 300-600 lumens and 8-15 years for professional systems.

- The direct answer DIY garden solar lights are cost-effective for low-output decorative lighting, but not for security or task lighting
Professional installation of a basic garden solar lighting system with 6 to 10 lights costs between £400 and £800 including labour and materials, based on 2026 MCS-registered installer quotes (MCS installer database, 2026). A comparable DIY garden solar lights system costs £80 to £200 from a UK retailer such as B&Q, Wickes or Screwfix, based on 2026 catalogue prices. Labour accounts for 60 to 70 per cent of the professional cost, and DIY eliminates this entirely (DESNZ solar lighting cost breakdown, 2026).
The price difference is straightforward. For basic decorative lighting around flowerbeds, paths or patios, the DIY route saves hundreds of pounds upfront.
DIY garden solar lights produce 80–150 lumens per unit, while professional systems reach 300–600 lumens
Light output is measured in lumens. A lumen is a unit of visible light emitted by a source. The higher the lumen number, the brighter the light.
Standard DIY solar path lights output 80 to 150 lumens per unit, using LED warm white bulbs powered by a 0.5 to 2 watt solar panel per light (Energy Saving Trust solar lighting fact sheet, 2026). Professional-grade low-voltage solar landscape lights, typically 12V DC systems, output 300 to 600 lumens from 10 to 30 watt panels. Professional systems use photovoltaic panels with 5 to 10 times the surface area of DIY units (MCS product performance register, 2026).
If you need bright light for security or for reading, a DIY system will not meet your needs. For subtle garden accent lighting, 80 to 150 lumens is sufficient.
DIY garden solar lights last 2–4 years; professional systems last 8–15 years
Battery lifespan is the main reason for the difference in longevity between these two options. DIY units use integrated rechargeable batteries, either nickel-metal hydride (NiMH) or lithium-ion (Li-ion), rated for 500 to 1,000 charge cycles. This equates to 2 to 4 UK winters (EST battery performance data, 2026).
Professional systems have separate battery banks, typically lead-acid or lithium iron phosphate (LiFePO4), with 3,000 to 5,000 cycle lifespans. Most DIY lights have sealed units, so the batteries cannot be replaced. Professional systems allow battery swaps, extending the overall system life. MCS installer warranty terms average 5 years for DIY-grade components and 10 years for professional-grade systems (MCS installer warranty terms, 2026).
If you want lights that last a decade or more, professional installation is the better choice. For occasional decorative use, the shorter lifespan of DIY lights may be acceptable.
Quick numbers cost, output, and lifespan comparison
| Metric | DIY garden solar lights | Professional-installed system |
|---|---|---|
| Typical upfront cost (6–10 lights) | £80–£200 | £400–£800 |
| Lumens per light | 80–150 | 300–600 |
| Panel wattage per light | 0.5–2W | 10–30W |
| Battery lifespan (charge cycles) | 500–1,000 | 3,000–5,000 |
| Warranty period | 1–2 years typically | 5–10 years |

DIY garden solar lights meet UK building regulations only if they are low-voltage and ground-mounted
UK Building Regulations Part P covers electrical safety for mains-voltage lighting. DIY solar lights are typically 12V or less and are therefore exempt from Part P requirements (Building Regulations Approved Document P, 2026).
Ground-mounted solar lights that use stakes or spikes do not require planning permission under Permitted Development rights (GOV.UK Planning Portal, 2026). Wall-mounted solar lights that are over 3 metres high or within 2 metres of a boundary may need planning permission. Most garden solar lights sold in UK retailers are designed to be ground-mounted and comply with these rules.
If you plan to attach solar lights to a wall, check your local planning authority guidance before installing.
MCS certification is required for professional installers but not for DIY garden solar lights
MCS stands for Microgeneration Certification Scheme. It is mandatory for professional solar installers who want their customers to claim payments under the Smart Export Guarantee (SEG) (Ofgem SEG guidance, 2026).
DIY garden solar lights do not feed electricity into the grid, so MCS certification is irrelevant for the homeowner doing a DIY install. To verify a professional installer, check the MCS register at mcs-certified.com or TrustMark for general electrical work (MCS website, 2026). What is MCS certification and do I need it
If you decide to hire a professional installer for a larger system, always verify their MCS certification before agreeing to any work.
The direct answer DIY garden solar lights are cost-effective for low-output decorative lighting, but not for security or task lighting
DIY garden solar lights are suitable for path edging, accent illumination, and decorative garden features where 80 to 150 lumens suffice. For security lighting requiring 300 lumens or more with motion sensors, or for task lighting on patios and steps, professional-installed low-voltage systems are required (EST lighting guidance, 2026).
The break-even point is around 10 lights. If you need more than 10 lights, or lights that operate reliably through the UK winter from October to March, professional installation becomes more cost-effective per lumen-hour (MCS case studies on winter performance, 2026).
For most UK homeowners with a small to medium garden who want subtle, decorative lighting, a DIY garden solar lights install is the sensible choice. For anyone needing bright, reliable, long-lasting lighting, professional installation is the better investment. Solar panel grants and funding for homeowners 2026
