Home Lighting GuideChoosing the Right Lighting for Every Room

Good lighting does far more than help you see — it shapes how a room feels, improves safety, reduces energy bills, and adds real value to a home. Yet lighting is one of the most underplanned aspects of any renovation or new build. This guide covers what to consider for each area of your home, from kitchens and bathrooms to gardens and driveways.

Why Professional Lighting Installation Matters

Many homeowners assume lighting is a straightforward DIY job. Replacing a like-for-like fitting often is. But running new circuits, adding downlights, installing outdoor lighting, or rewiring lighting in a bathroom or kitchen is notifiable work under Part P of the Building Regulations — meaning it must be carried out by a registered electrician or inspected by Building Control.

Beyond compliance, a qualified electrician will also ensure your circuits are correctly rated, your outdoor fittings have the right IP rating for the environment, and that bathroom fittings comply with the zone regulations that govern where different types of light can safely be installed.

Kitchen Lighting

The kitchen is the room where lighting makes the biggest practical difference. A single central pendant is rarely enough — it creates shadows across worktops and makes cooking unnecessarily difficult. A well-planned kitchen typically combines:

• Recessed LED downlights for general, even illumination across the room.
• Under-cabinet strip lights to illuminate worktops directly — essential for food preparation.
• Island pendants where applicable, for both task lighting and visual character.

LED downlights use around 80% less energy than older halogen equivalents and last significantly longer. If your kitchen still has halogens, upgrading to LEDs is one of the most cost-effective improvements you can make.

Bathroom Lighting

Bathroom lighting is governed by strict zone regulations (BS 7671) that specify what types of fittings can be installed in different areas relative to water sources. In Zone 0 (inside the bath or shower) and Zone 1 (directly above), fittings must be low voltage and carry a minimum IP65 rating. Zone 2 (within 60cm of the shower or bath) requires IP44 as a minimum.

Shaver sockets and extractor fans also need to be correctly specified and placed. A bathroom that's had DIY electrical work without proper certification may cause problems at the point of sale — or worse, present a genuine safety risk.

Living Rooms and Bedrooms

These rooms benefit from layered lighting — a combination of ambient (general), task (reading or desk lamps), and accent (feature or decorative) lighting. Smart dimmer switches work well here, allowing you to adjust the mood without needing multiple circuits. Ensure any dimmer switches fitted are LED-compatible — older dimmer switches often cause LED bulbs to flicker or fail prematurely.

Exterior and Security Lighting

Outdoor lighting serves both practical and security purposes. A well-lit exterior deters opportunistic intruders, improves safety on driveways and paths, and makes your property look welcoming. Common options include:

• PIR floodlights — triggered by movement, ideal for driveways, side gates, and rear access points.
• Always-on wall lanterns — for porches and front entrances where consistent light is preferable.
• Garden and pathway lighting — low-level LED lighting that defines paths and highlights landscaping.
• Garage and outbuilding lighting — functional strip or bulkhead lighting for workshops, garages, and storage areas.

All outdoor fittings must carry an appropriate IP rating for their installation environment. Fittings installed in exposed locations typically require IP65 or higher. Outdoor wiring must also be correctly armoured or adequately protected where it runs below ground.

For comprehensive exterior security, outdoor lighting pairs well with CCTV cameras and intruder alarm systems.

Garden Lighting

Garden lighting has come on enormously in recent years, with low-voltage LED systems making it practical and affordable to illuminate trees, borders, water features, and outdoor seating areas. A dedicated outdoor lighting circuit — run from the consumer unit and protected by an RCD — gives you flexibility and means you're not relying on extension leads or plug-in systems that are not intended for permanent outdoor use.

Switching to LED: Is It Worth It?

Yes — unambiguously. LED bulbs and fittings use a fraction of the energy of older incandescent or halogen alternatives, last far longer (typically 15,000–25,000 hours versus 1,000–2,000 hours for halogens), and produce very little heat. The upfront cost of LEDs has fallen dramatically in recent years, and most households see the investment recovered through energy savings within a relatively short period.

If your property still has recessed halogen downlights — particularly common in kitchens installed before 2015 — a direct LED replacement is usually straightforward and can be done in a single visit.
