Good lighting transforms a garden after sunset. On the Lisbon coast, where summer evenings are long and warm, it is what turns a garden into a living space – and it adds safety on steps, paths and driveways all year round. Lighting is also much cheaper to install during landscaping or paving works than afterwards. Here is what garden lighting costs in Portugal in 2026.
Garden Lighting Prices at a Glance
Indicative 2026 prices per light point, supplied and installed with cabling in the Cascais, Sintra and Lisbon area, excluding VAT.
| Light type | Typical use | Price per point |
|---|---|---|
| Path / bollard light | Paths, driveway edges | €120 – €300 |
| Spike uplight | Trees, shrubs, sculptures | €100 – €250 |
| In-ground uplight | Façades, palms, walls | €200 – €450 |
| Step or wall recessed light | Stairs, retaining walls | €90 – €220 |
| Underwater pool light | Pools | €250 – €700 |
| Festoon / string lights | Terraces, pergolas | €15 – €40 per metre |
A typical villa garden of 400–800 m² with 20–30 light points usually costs €4,000 – €9,000 for a complete, well-designed scheme.
Low Voltage or Mains Voltage?
Low-voltage (12/24 V) systems use a transformer near the house and thin cables to each light. They are safer around children, pets and water, easier to adjust when plants grow, and ideal for gardens. Cables still need protection, but trenches can be shallower.
Mains-voltage (230 V) systems suit long driveways, powerful façade lights and gates. They require armoured cable or conduit at proper depth, waterproof junction boxes and residual-current protection, and must be installed by a certified electrician.
Most gardens use a combination: 230 V for the main supply and long runs, low voltage for the planting areas.
What Affects the Price?
- Number of light points – the main driver. Fewer, well-placed lights look better than many random ones.
- Fixture quality – marine-grade aluminium or brass resist salt air near the sea; cheap fittings corrode in two or three winters.
- Trenching – easy in planted beds, expensive under existing paving.
- Controls – a simple timer and dusk sensor (€80–€200) versus a smart system with zones and app control (€400–€1,500).
- Design – a professional lighting plan typically costs €300–€1,000 and avoids glare and dark spots.
Lighting Design Principles
- Light the effect, not the source – you want to see the tree, not the bulb.
- Use warm white (2,700–3,000 K) for a natural, welcoming atmosphere.
- Safety first – steps, level changes and the route from the car to the door.
- Layers – combine low path lighting, accent lighting on key features and soft ambient light on terraces.
- Respect the night sky and neighbours – aim lights downward where possible and avoid spill onto neighbouring windows. Many Sintra properties border natural areas where wildlife is sensitive to light.
Lighting Key Features
Trees and palms look best lit from below with one or two uplights placed slightly in front, so the trunk and canopy are both visible. Olive trees and palms are particularly effective.
Façades benefit from narrow-beam in-ground lights that graze the texture of stone or render. Too much light flattens the building; a few well-spaced points create depth.
Pools are often the centrepiece at night. Underwater LEDs in warm white or adjustable colour, combined with low lighting on the deck, create atmosphere without glare. All pool lighting must meet the safety requirements for wet zones.
Retaining walls and steps are ideal for recessed lights that add safety and highlight the stonework at the same time.
Driveways and entrances need enough light for safe arrival, often combined with motion sensors to save energy and add security.
Plan Lighting With Paving and Irrigation
The best moment to install garden lighting is during landscaping, before paving and turf go down. Conduits can share trenches with irrigation lines (kept at a safe separation) and sleeves can be laid under driveways and paths for almost no extra cost. Retrofitting the same scheme later often costs 30–50% more. If you are planning a new garden, see our landscaping cost guide and paving cost guide to budget everything together.
Example Budget: 600 m² Garden in Cascais
| Item | Estimated cost |
|---|---|
| Lighting design | €500 |
| 10 path lights along driveway and paths | €2,000 |
| 8 uplights on trees and palms | €1,600 |
| 2 in-ground façade lights | €700 |
| 6 step lights | €900 |
| Transformers, cabling, trenching | €1,400 |
| Smart controller with 3 zones | €600 |
| Total (before VAT) | €7,700 |
How Much Does It Cost to Run?
Modern LED garden lights use very little energy. Twenty-five lights averaging 5 W each, on for five hours a night, consume roughly 230 kWh per year – around €40–€60 at typical Portuguese tariffs. Using a dusk sensor and switching off after midnight cuts this further.
What About Solar Garden Lights?
Solar lights are cheap and need no cabling, but their output is weak, the light colour is often cold, and batteries fade after one or two years. They work for marking a path in a small garden, not for a designed scheme. For a quality result, wired LED remains the standard.
Maintenance
Clean lenses once or twice a year, re-aim spotlights as plants grow, trim vegetation that blocks light and check seals before winter. Good fixtures with replaceable LED modules last 15 years or more.
Frequently Asked Questions
Do I need an electrician for garden lighting?
For any 230 V work, yes – it must be done by a certified electrician. Low-voltage circuits after the transformer are simpler, but the supply point still needs proper protection.
Can lighting be added to an existing garden?
Yes. Cables can usually be laid through beds with minimal disturbance; crossing paving is the costly part.
How many lights does a garden need?
Fewer than most people think. A typical villa garden looks best with 15–30 carefully placed points.
Which fixtures last near the sea?
Marine-grade aluminium, 316 stainless steel or brass with IP65–IP68 protection.
