O’Brien v Robinson: when does a landlord have notice of disrepair?

Quick answer

O’Brien v Robinson is the leading authority behind an important rule in housing disrepair cases: where a defect is inside the part of the property occupied by the tenant, a landlord will not ordinarily be liable for failing to repair it before the landlord has the necessary notice or knowledge. Lord Diplock explained that the landlord may have sufficient information about a defect to be put on inquiry as to whether repair works are needed. The Court of Appeal later restated the rule as asking whether the information would put a reasonable landlord on inquiry, followed by a failure to carry out the necessary works with reasonable expedition.

What happened?

The tenants occupied part of a house owned by their landlord.

In November 1968, the bedroom ceiling collapsed and injured them. The ceiling must have been defective immediately before it fell, and the landlord was subject to a statutory repairing obligation covering the structure of the dwelling.

The difficulty was that the landlord had not been told that the ceiling was defective and did not otherwise know of the problem before the collapse.

The tenants argued, in effect, that the repairing covenant should make the landlord responsible because the property had objectively fallen out of repair.

The dispute therefore reached the House of Lords on a fundamental question: does a landlord breach an obligation to keep premises in repair as soon as disrepair exists, or only after the landlord knows enough about the problem and has had an opportunity to deal with it?

The House of Lords dismissed the tenants’ appeal.

What did the court decide?

The House of Lords held that, for this kind of defect within the tenant’s dwelling, the landlord’s repairing obligation was not an absolute guarantee that the property could never fall out of repair.

The landlord first had to have the necessary knowledge of the defect.

That knowledge does not have to come from a perfectly drafted written repair notice.

Lord Diplock explained that the landlord may have information about the existence of a defect such as would put him on inquiry as to whether works of repair to it were needed.

The Court of Appeal later restated that line of authority in British Telecommunications plc v Sun Life Assurance Society plc [1996] Ch 69. Nourse LJ put it as two things together: information about the defect such as would put a reasonable landlord on inquiry as to whether works of repair were needed, and a failure to carry out the necessary works with reasonable expedition thereafter.

That later case did not create the notice rule. It describes itself as summarising the authorities culminating in O’Brien v Robinson, and the “reasonable landlord” wording belongs to that restatement rather than to Lord Diplock’s own words.

Once the landlord has the necessary notice or knowledge, it must then be allowed the period reasonably required to investigate and carry out the necessary work.

This is why two distinct questions arise in many Section 11 disputes.

  • When did the landlord know enough about the problem?
  • After that point, did it act within a reasonable time?

The second question does not arise properly until the first has been answered.

What rule does this case establish?

The practical rule from O’Brien v Robinson is that a landlord is not ordinarily liable under a repairing covenant for a defect inside the tenant’s dwelling before the landlord has notice or knowledge sufficient to put it on inquiry.

That is narrower than saying: “The tenant must identify exactly what is broken.”

A tenant may report a symptom rather than its technical cause.

For example, repeated reports that water is entering a bedroom may put the landlord on inquiry even if the tenant cannot say whether the cause is defective flashing, a roof covering, masonry or a leaking pipe.

The case therefore concerns knowledge of the need for investigation and repair, not the tenant’s ability to diagnose building pathology.

It should also not be turned into a universal rule for every part of a building. Different questions can arise where the defect is in a part retained or controlled by the landlord rather than hidden within the tenant’s own demise. That distinction is dealt with elsewhere in the modern authorities.

Why does this matter to tenants?

It explains why evidence of reporting repairs is so important.

An email, repair-portal entry, text message, call log, complaint, contractor visit or inspection record can help establish when the landlord knew enough about the condition of the property. Our guide to what counts as notice covers how that evidence is built.

It also explains why a landlord cannot necessarily defeat a claim by saying: “You never told us what was causing the damp.”

A tenant is not normally expected to diagnose whether water penetration comes from the roof, pointing, guttering or another building defect. What matters is whether the information available to the landlord should reasonably have caused it to investigate.

At the same time, the case is a warning against assuming that the existence of disrepair automatically proves a historic breach.

If nobody had reported a hidden defect, the landlord had not discovered it and there was nothing else putting the landlord on inquiry, the date when liability arose may be later than the date when the physical defect first existed.

That is why RemedyBridge treats notice and reasonable time as separate parts of the repair chronology.

Primary source

O’Brien (A.P.) and Another (A.P.) v Robinson, House of Lords, 1973; commonly reported as O’Brien v Robinson [1973] AC 912.

The available judgment text confirms that the case concerned the landlord’s statutory obligation to keep the structure in repair and whether liability arose without notice of the defect.

The official Find Case Law service does not hold this judgment, and no free primary text has been located. The Appeal Cases report is the citation of record.

Supporting authority

British Telecommunications plc v Sun Life Assurance Society plc [1996] Ch 69 (CA) is the source of the developed “reasonable landlord on inquiry” formulation, coupled with reasonable expedition once the landlord is on inquiry. It is cited here by its law report; no free primary text has been located, and none is invented for the sake of uniformity.

Edwards v Kumarasamy [2016] UKSC 40 is the later Supreme Court authority confirming the O’Brien notice rule and its limits — in particular the distinction between premises in the tenant’s possession and parts retained by the landlord. It is a Supreme Court decision, not the Court of Appeal restatement.
