Review, Advise and Negotiate

The engineering services sector is heavily regulated which makes it a unique trading environment. Whether you are trading with the public or private commercial clients (B2B) or consumers (B2C), our guidance notes and templates are here to help.

Our expertise covers a range of issues from; PQQ and tendering issues, letters of intent, pre-construction agreements, main contracts, sub-contracts, sub-subcontracts, design/consultancy agreements, off-site/vesting certificates, materials agreements, and more.

We focus on developing guidance and templates in areas our Committee of Members and our helpdesk data, tell us are most useful/urgent – for example: payment or inflation - but if we don’t have a guidance note or template, we can create it – just reach out to the Legal & Business helpline. 

In the construction and facilities management sectors, other than in the consumer market, clients attempt to dictate the terms and conditions upon which ECA Members are engaged to carry out their works.
There are two ways in which ECA Members are commonly asked to enter into contracts with their clients, namely:

  1. Modified standard form contracts i.e. JCT or NEC
  2. In-house bespoke terms and conditions which are procured as an investment in commercial risk protection by the client in question

There are two reasons why modified standard forms or bespoke forms of contract come about:

  1. To recognise specific project risks, e.g. if the project is on a high security risk site, there may be additional contractual requirements surrounding security.
  2. Commercial risk transfer – in order to de-risk the commercial model of their own business, clients will often seek to push, either through the standard form modifications or the bespoke terms, as much commercial risk downwards within the contractual chain as possible.

The latter approach is intended to safeguard the profitability of their businesses, but it will often place unmanageable and overly onerous risk on to the party carrying out the works.

ECA has used its collective experience to assimilate a guidance document that:

a) identifies common areas of standard form contracts – which broadly represent the industry norm for what is acceptable risk allocation – and/or bespoke terms, and identify where those issues are modified to an ECA Member's detriment;

b) outlines the risk of those types of clauses;

c) suggests a risk proportionate approach and rationale for finding and negotiating a compromise which aligns the risks involved with the parties who are realistically and proportionately in a position to manage those risks.

ECA wishes to identify and inform the engineering services sector and ECA Members’ decision on what ‘fair, reasonable and good contractual practice’ looks like. ECA remains committed to fair and open competition and this document is not designed to in any way dictate what may be an appropriate risk allocation for a specific project, or act as a substitute for ECA Members obtaining project and context specific legal advice.

This resource will be updated as the law evolves and as terms and conditions revise to reflect a change in the working environment.

Collateral warranties are a common security document required by developers, funders, clients, purchasers, and tenants — and understanding them is essential for protecting your business.

If you are looking to enhance your learning and understanding, you may be interested in ECA’s Growth Hub where we have a range of courses designed specifically for ECA Members to gain a broader deeper understanding of the issues involved.

Keep your eyes peeled for more Collateral Warranties Workshops being delivered in 2026 through the Growth Hub!
