Rights of Light and Commercial Development

Rights of light can stop or shrink a development, or cost a lot to buy off. Any commercial landlord thinking about building or extending needs to understand them.

What a right of light is

A right of light is a right for a building to receive a certain amount of natural light through defined windows, which can be acquired over time. If your development would reduce a neighbour's light below the protected level, they may have a claim, potentially including an injunction to stop or cut back the scheme, or substantial damages.

Why it matters for development

Rights of light are one of the biggest risks in urban development. A neighbour with a right of light can hold real leverage, so schemes are often designed, insured or negotiated around them. Discovering a problem late can be very expensive.

Managing the risk

• Assess early: a rights of light survey identifies affected neighbours and the extent of any infringement.
• Negotiate: reach agreement with affected owners, often for a payment.
• Insurance: rights of light insurance can cover the risk in some cases.
• Design: adjust the scheme to reduce or avoid the infringement.

Part of the development picture

Rights of light sit alongside planning, easements and the development appraisal as things to resolve before committing to a scheme. Take specialist surveying and legal advice early, because the downside is an injunction.

Can rights of light stop my development?

Yes. If your scheme reduces a neighbour's protected light, they may have a claim, potentially including an injunction to stop or cut back the scheme.

How do I manage rights of light risk?

Assess it early with a survey, negotiate with affected owners, consider insurance, and design the scheme to reduce any infringement.
