Quality Assurance definition

What does Quality Assurance mean? Quality assurance (QA) describes the documented systems and oversight by which a party (for example, a developer, contractor or manufacturer) ensures that goods, works or services meet agreed specifications, regulatory requirements and industry standards throughout design, manufacture and delivery. It is a descriptive term rather than a defined legal concept. Contracts in England and Wales, Scotland, Northern Ireland and Ireland commonly specify QA by reference to recognised standards (such as ISO 9001), regulatory regimes (for example, Good Manufacturing Practice for medicines and medical devices) or the employer’s requirements/technical specifications. Typical legal features include QA plans, audit and inspection rights, acceptance testing, record‑keeping,...

Combined Heat and Power Quality Assurance (CHPQA) in the UK: certification, self-assessment, monitoring and audit requirements and links to subsidy eligibility

Published by a LexisNexis Energy expert

Practice notes

What is the ?

The chpQA is a programme operated on behalf of the Department for Energy Security and Net Zero (DESNZ), in collaboration with the Scottish Executive, the Welsh Parliament, and the Northern Ireland Department of Enterprise, Trade and Investment. DESNZ was formed on 7 February 2023 and has assumed the energy portfolio and duties of the former Department for Business, Energy and industrial strategy (beis), which no longer exists, including its roles in respect of the CHPQA. The scheme’s objective is to systematically assess, track and raise the overall quality of combined heat and power (CHP) in the UK. CHP is a key component of the UK’s low‑carbon aims, as it captures waste energy from electricity generation to supply heat directly to domestic and non‑domestic premises across the UK (typically as hot water and steam moved through a network of pipes; it is therefore a notably efficient mode of generation and is sometimes also termed ‘co‑generation’). For further information on CHP projects generally, see Practice Note: An introduction to Combined Heat and Power (CHP) Projects.

What are the benefits of the CHPQA?

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
