JDJ Commercial Services

JDJ Commercial Services provides senior-level commercial leadership to residential construction contractors across Essex, London and the surrounding areas,, without the cost of employing a full-time Commercial Director.

With over 20 years of contractor-side commercial experience, we help construction businesses protect profit, reduce risk and maintain stronger commercial control across their projects.

Our services include:

• Commercial Management
Senior-level oversight and commercial control across individual projects or wider portfolios. We support contractors with commercial strategy, financial reporting, change management, risk and communication from the early stages through to completion.

• Cost Planning and Forecasting
Clear, data-backed cost planning and forecasting that helps directors understand their financial position, identify potential issues and make better-informed decisions.

• Contract Review and Negotiation
Practical reviews of client and subcontract agreements to identify commercial risks, strengthen contractual positions and support negotiations.

• Project Audits and Commercial Recovery
Independent reviews of live, struggling or stalled projects to identify profit leakage, recover value and restore effective commercial control.

• Dispute Avoidance and Strategy
Support with documentation, communication and commercial processes to prevent issues from escalating and keep projects moving.

JDJ typically supports residential contractors turning over approximately £2m–£20m, particularly businesses managing several projects simultaneously or requiring stronger oversight of cost, contracts and risk.

Support can be provided through a focused Commercial Health Check or on an ongoing monthly retainer. This gives contractors access to experienced, independent commercial leadership as and when they need it.

Our approach is practical, straightforward and grounded in the realities of live construction projects: protect the project, strengthen the numbers and keep everyone aligned.
