UK: Main Contractor Insolvency – Contract Quick Guide

Last Updated: 17 January 2018
Article by Michael Hiscock and Caroline Benfield

In light of the recent Carillion demise, this guide provides a starting point on common forms of contract for both employers and subcontractors looking at how insolvency affects the supply chain from both directions. The table below is a quick reference for the processes in the main contract and subcontracts for the scenario where the main building contractor has gone bust.

Of course every contract is different, whether it is bespoke amendments to a JCT format, or a PFI pass down agreement, or something else, so you must always check the contract to see what it actually says.

Also, people often forget to check the notice provisions in a contract – so if you have to serve a notice, check if there is a particular procedure that you must follow to achieve valid service.

There are also issues surrounding redundancies, corporate insolvency processes, cancelling goods purchase and hire contracts, refinancing, corporate restructuring etc, all of which Wright Hassall is able to cover.

If you are a subcontractor, check the collateral warranties to see if you can persuade a bank or purchaser to step in and pay you to finish the job.

If you are an employer operating under an unamended JCT format, retentions should be held on trust in a separate bank account, so don't assume you can automatically claim that money.

And finally, don't forget that a liquidator will appoint claims consultants / QS firms to maximise recovery for shareholders, so final account claims can still be tested in the normal way.

  • instruct the contract to assign the benefit of subcontracts

use any equipment that remains on site and release it when no longer required

The amount due is:

  • a deduction of the forecast of the additional cost to the employer of completing the whole of the works.

NEC3 Engineering and Construction Subcontract

The subcontractor may only terminate for a specific reason. If the subcontractor terminates for contractor insolvency, the subcontractor leaves site, removes its equipment, and claims (i) amounts due assessed as per the relevant Option plus (ii) defined cost of plant and materials, plus retentions, plus the direct fee percentage applied to the difference between the price for work done to dates and the total price for the subcontract works.

As soon as reasonably practicable after termination, the Engineer must value the part of the works complete prior to termination and assess all sums due to the contractor at the date of termination.

If the cost to complete exceeds the termination value, the difference is recoverable.
