What Is a Right to Light?
Easement entitling building owner to sufficient daylight through defined apertures for ordinary comfortable use. Colls v Home and Colonial Stores [1904] AC 179 HL: not a right to all light — sufficient for comfortable use as dwelling or business. Benefits specific windows, not the building generally. Expert daylight surveyors quantify using Waldram methodology and BRE Digest guidelines.
How Rights to Light Are Acquired
Express grant by deed; implied grant (Wheeldon v Burrows [1879]; LPA 1925 s.62) on sale/lease of part; prescriptive right under Prescription Act 1832 s.3 — 20 years' actual enjoyment through defined apertures, uninterrupted, without consent, gives absolute indefeasible right. Registered land does not prevent prescription for rights to light.
What Constitutes Infringement
New structure reduces light below level needed for ordinary comfortable use of the protected room. Expert daylight survey required. Planning permission irrelevant: Heaney v Leeds City Council [2020] EWCA Civ 1610 — grant of planning permission does not authorise infringement of a private right to light. Risk of injunction requiring demolition even of completed structures.
Remedies — Injunction or Damages
Primary remedy: injunction (interlocutory or mandatory — can require demolition). Damages in lieu (SCA 1981 s.50): court weighs Shelfer criteria — injury small; measurable in money; small payment sufficient; oppressive to grant injunction. Midtown v City of London Real Property [2005]: damages in lieu increasingly awarded for completed development. Release payment: developer negotiates lump sum with benefiting owner pre-works.
Prevention — Notional Obstruction and Indemnity Insurance
Rights of Light Act 1959: register 'light obstruction notice' as local land charge — legal effect of actual physical obstruction; interrupts prescriptive period without any physical works. Indemnity insurance: covers injunction or damages award risk; premium varies with strength of right. Deed of release: definitively extinguishes right; negotiated with benefiting owner; most secure solution.
