Jaevee Homes Ltd v Fincham [2025]

Introduction

This UK Technology and Construction Court decision addresses whether a construction contract can be formed through informal digital communications — in this case, WhatsApp. Despite subsequent issuance of formal contract documents, the contractor proceeded with the works after receiving a simple “Yes” message confirming the award. When a payment dispute later arose, the contractor relied on this informal communication as the contractual basis for its adjudication.

The Court upheld the adjudicator’s finding that the WhatsApp exchange created a binding contract under English common law. The essential elements — scope, price, and intention to create legal relations — were sufficiently established through earlier correspondence and the WhatsApp confirmation. The judgment demonstrates that even minimal digital exchanges can create enforceable contractual obligations in UK construction projects.

Key Takeaways

1. WhatsApp messages can create binding UK construction contracts
A short confirmation in a messaging app can constitute valid acceptance where essential terms are already understood.

2. Absence of formal contract documentation is not fatal
If scope and price are clear, and parties intend to be bound, English common law will enforce the agreement.

3. Statutory payment rules will fill gaps
The Construction Act implied the payment regime, enabling the contractor to rely on default payment provisions.

4. Parties’ conduct is highly influential
Work commencing and being permitted reinforced the mutual intention to enter contractual relations.

5. Businesses must manage digital communication risk
WhatsApp, SMS, and similar platforms can unintentionally formalise agreements and trigger contractual rights.

Jurisdiction Note
This ruling is grounded in English common law and the UK Construction Act. Other jurisdictions — particularly civil law systems — may reach different conclusions regarding the enforceability of informal digital communications. Parties operating internationally should seek jurisdiction-specific advice.
