Renovation Lighting Guide

Key Takeaways

  • Good lighting uses three layers: ambient, task and accent.
  • Plan lighting and circuits at first fix, before plastering.
  • Dimmable, layered lighting transforms how a room feels.
  • Kitchens and bathrooms need task lighting on dedicated, compliant circuits.
  • Lighting is cheap to plan in early and expensive to add later.

Lighting is one of the most underrated parts of a renovation, yet it shapes how every room looks and feels. Planned well and early, it costs little; added late, it means tearing into finished walls. Here is how to get it right.

Light in three layers

Great lighting combines three layers, ideally all dimmable:

  • Ambient: general background light that fills the room.
  • Task: focused light where you work, such as under-cabinet lights and bathroom mirror lights.
  • Accent: decorative highlights on artwork, shelving or features.

A single ceiling light does none of this well, which is why thoughtful layering makes such a difference.

Plan it at first fix

Lighting circuits and positions are set during first fix, before plastering. Decide every fitting, switch position and dimmer at the design stage, because moving them later means chasing into finished walls. This is the single cheapest point to get lighting right. See the order of works.

Room by room

Kitchens need shadow-free task light over worktops and the island, plus ambient and accent layers. Bathrooms need fittings rated for their zone, on a compliant Part P circuit. Living rooms and bedrooms benefit most from dimmable layers for flexibility.

We design and install layered lighting as part of every renovation. To plan lighting for your project, contact us or call 07472 424 226.

FAQ

Frequently Asked Questions

What are the three layers of lighting?

The three layers are ambient (general background light, such as ceiling fixtures), task (focused light for activities, such as under-cabinet lights and mirror lights), and accent (decorative or highlight lighting, such as spots on artwork or shelf lighting). Combining all three, ideally on dimmers, gives a flexible, comfortable scheme.

When should I plan lighting in a renovation?

Plan lighting at the design stage and finalise it before first fix, when cables and circuits are run, because adding or moving lights after plastering means chasing into finished walls. Deciding light positions, switching and dimming early is one of the cheapest ways to dramatically improve a room.

How should I light a kitchen?

Light a kitchen in layers: ambient ceiling lighting, task lighting under wall units and over the island and sink, and accent lighting in glazed cabinets or plinths. Worktops need shadow-free task light, and an island often takes pendant lights that also zone the space in open-plan rooms.

What lighting is allowed in a bathroom?

Bathroom lighting must be suitable for the zone it sits in, with appropriate IP ratings near the bath and shower, and it must be installed on a compliant circuit certified under Part P. Layered lighting, including mirror and recessed ceiling lights, works well, but safety zones and ratings come first.

Are dimmers worth it?

Yes. Dimmers are inexpensive and transform how a space feels, letting one room shift from bright and practical to soft and relaxing. Fit them on the main circuits in living spaces, kitchens and bedrooms. Make sure the dimmer is compatible with LED fittings to avoid flicker.
