Legal contracts in property investment can be a minefield, and getting them wrong can cost investors thousands. That’s why understanding JCT contracts (Joint Contracts Tribunal) - the most commonly used construction contracts in the UK - is crucial for property investors and developers.
To shed light on this complex subject, we invited Tony Power, an academic lawyer, property investor, and contract specialist, to share his expertise. Tony is a lecturer at Canterbury Christ Church University with deep knowledge of contract, employment, and property law. He has worked as a police officer, legal trainer, and advocate in county courts, helping property entrepreneurs navigate legal challenges.
In this session, Tony breaks down JCT contracts, explaining their purpose, the different types, and how to avoid common legal pitfalls.
“The more precise you are, the more protected you are.”
JCT contracts vary depending on the size and complexity of the project. The five main types include:
Minor works building contract – Ideal for small refurbishments and extensions.
JCT intermediate contract – Best suited for medium-sized projects with some complexity.
JCT standard building contract – Used in large-scale developments requiring detailed administration.
JCT design and build contract – A single contract where the contractor handles both design and construction.
JCT measured term contract – Used for long-term maintenance agreements across multiple projects.
Choosing the right JCT contract depends on the size, risk, and complexity of the project. Consulting a quantity surveyor, legal professional, or experienced project manager can help ensure you pick the right one.
Many investors make critical mistakes when signing contracts, leading to legal disputes and financial loss. Here are some key pitfalls to avoid:
One common mistake is undefined payment terms. Without clear terms, cash flow issues and unexpected delays can arise. It’s crucial to negotiate stage payments that align with your financing and project timeline.
Another issue is the inadequate scope of work definitions. Vague contracts can lead to extra costs and disputes. A detailed schedule of works should outline every material, finish, and workmanship standard.
Delay protection is often overlooked. JCT contracts don’t automatically include penalties for missed deadlines. Adding a liquidated damages clause can protect you from financial losses due to delays.
Risk allocation must be clearly defined. Many investors fail to specify who is responsible for unforeseen issues like asbestos, foundation problems, or structural defects. A well-drafted force majeure clause helps mitigate unexpected liabilities.
Lastly, many contracts have weak termination clauses, locking investors into agreements even if a contractor underperforms. A strong termination clause ensures you can exit the contract without financial penalties.
“Don’t assume the contract is perfect—read it thoroughly and amend it to fit your project.”
To maximise the benefits of JCT contracts, property investors should focus on a few essential strategies.
First, customise payment terms to match project milestones rather than arbitrary timeframes. Holding back 5–10% of each payment as retention ensures work is completed to a high standard before final payments are made.
Second, strengthen delay protection. Adding penalties for missed deadlines and limiting contractors’ ability to claim extra time for minor issues helps maintain efficiency.
Next, be precise about quality standards. Using a detailed schedule of works, specifying acceptable substitutes for unavailable materials, and defining workmanship expectations prevent misunderstandings.
Additionally, clarify risk allocation early on. Defining responsibility for unexpected issues like asbestos removal ensures investors aren’t hit with surprise costs.
Finally, contractor warranties are essential. At least a 12-month warranty should cover defects after project completion, protecting investors from additional expenses.
JCT contracts provide a structured legal framework for property investors and developers, helping to mitigate risks, avoid disputes, and streamline construction projects. However, they are not foolproof—understanding and customising these contracts is essential.
By following the guidance shared by Tony Power, investors can ensure their contracts are legally sound, financially secure, and fit for purpose. Seeking professional advice can save you thousands in the long run.
