Rights to light are private property rights that benefit both residential and commercial buildings. They can be acquired by express written grant from one neighbouring landowner to another, by virtue of archaic law or by prescription if light has come through a window (or aperture) for 20 uninterrupted years.
Why is reform necessary?
Typically, disputes arise when a developer proposes to erect a building that may impact a neighbour's right to light. These often cause severe delays to development projects and uncertainty invariably operates as a blight in relation to neighbouring properties. Delays average 27 months with a mean cost of GBP 6.86m (according to the responses to the British Property Federation survey).
The lack of certainty in the law is largely responsible for this. The case of HKRUK II (CHC) Ltd v Heaney  increased the uncertainty surrounding the question of when an injunction or damages should be awarded, after the High Court ordered the demolition of two floors of a new building that had already been let.
The Law Commission Report
The Law Commission published a report on 4 December 2014 proposing to reform the current law on rights to light. The aim is to simplify the law in a way that strikes a fair balance between the interest of landowners and the need not to impede property development.
The Law Commission did not adopt its previous recommendation that prescriptive rights to light should be abolished, instead choosing to make prescription operate more straightforwardly.
What are the recommendations?
Replacing the acquisition of rights to light by prescription with one straightforward statutory scheme. Updating the current regime that allows landowners to block prescription by the registration of a local land charge. A new statutory test based on proportionality to clarify when Courts may order damages rather than an injunction. The Court will not grant an injunction to restrain the infringement of a right to light if doing so would be a disproportionate means...
