Central London Property Trust v High Trees House – 1947

In 1947, the English High Court grappled with a pivotal question in Central London Property Trust v High Trees House, shaping the landscape of contract law. The dispute, between a landlord (CLPT) and a tenant (HTH), hinged on the enforceability of an informal rent reduction during wartime hardship, illuminating the crucial principle of promissory estoppel in protecting reasonable reliance on promises.

Facts of the Case

In 1937, CLPT leased a block of flats in London to HTH for 99 years at an annual rent of £2,500. However, the outbreak of World War II in 1939 drastically reduced occupancy, leaving HTH struggling to meet the rent. In January 1940, HTH approached CLPT for a temporary rent reduction, and a new agreement was reached: £1,250 per annum until war conditions improved. HTH then consistently paid the reduced rent. By 1945, London began recovering, and the flats reached full occupancy. However, CLPT, seeking to capitalize on the improved situation, demanded the full original rent and backdated rent arrears for the entire wartime period.

Issues of the Case

The central legal question revolved around CLPT’s attempt to revoke the agreed-upon rent reduction despite its reliance by HTH:

  • Could CLPT enforce the initial lease agreement for the full rent after promising and accepting the lower rent for five years, even without a formal legal document for the reduction?
  • Did HTH’s reliance on the reduced rent and subsequent actions in managing the property create a legal defense against CLPT’s demand for the full rent and arrears?

Arguments Presented

Central London Property Trust:

  • The original lease agreement remains the legally binding document, and the temporary rent reduction was a verbal concession intended to alleviate immediate wartime hardship, not to supersede the existing contract.
  • No formal consideration (exchange of value) accompanied the rent reduction, rendering it unenforceable as a separate agreement.

High Trees House:

  • CLPT’s promise to accept the lower rent, though informal, was relied upon by HTH to manage their finances and maintain the property during a financially challenging period.
  • Denying the promised rent now would cause HTH significant hardship, as they had adjusted their financial structure in good faith based on CLPT’s assurance.

Court’s Decision and Reasoning

The High Court, in a landmark decision, found partially in favor of HTH. Their reasoning centered on:

  • The principle of promissory estoppel: CLPT’s promise, despite lacking formal consideration, created a duty not to renege on it due to HTH’s reasonable reliance and potential detriment if the promise were broken.
  • However, the estoppel only applies to the specific period during which HTH relied on the reduced rent; it does not indefinitely override the original lease agreement.

Therefore, CLPT could not claim the full rent for the period during which the reduced rent was accepted, but they were entitled to the original rent from that point forward.

Impact and Analysis

Central London Property Trust v High Trees House had a profound impact on contract law and the application of promissory estoppel:

  • Strengthened the principle of promissory estoppel as a vital defense against unfair revocation of informal promises relied upon in good faith.
  • Introduced flexibility in applying estoppel by limiting its protection to the specific period of justified reliance, preventing unintended and perpetual contract modifications.
  • Sparked ongoing debates about the balance between protecting reliance on informal promises and maintaining the sanctity of formal contracts.


Central London Property Trust v High Trees House remains a cornerstone in the development of promissory estoppel, reminding us that fairness and good faith play a crucial role in contracts beyond mere legal formalities. The case emphasizes the importance of protecting reasonable reliance on promises while maintaining a framework for upholding contractual obligations. As legal and societal landscapes evolve, this case offers invaluable insights into navigating the complexities of contractual relationships and balancing justice with the enforceability of agreements.
