Bespoke in-house training that helps every trade understand how their work affects building performance

Trade-Specific Training for Construction Site Teams

Good building performance depends on getting the details right, and every trade has a part to play. Trade-specific training is bespoke, in-house construction training that teaches each trade (groundworkers, insulation installers, airtightness specialists, and others) exactly how their day-to-day decisions affect a building's energy performance and quality. Coaction delivers trade-specific training to Tier 1 contractors and their supply chains across the UK, helping teams working towards Passivhaus, EnerPHit, AECB, and other performance standards understand what good delivery looks like in practice.
Why does trade-specific training matter for site teams?
Many building performance issues trace back to small, specific details on site: a gap in insulation, an incorrectly installed membrane, or a poorly coordinated interface between trades. These are rarely failures of intent, they're failures of understanding.
General training gives site teams useful oversight. But different trades face different risks,so a general session can only go so deep. For example, groundworkers don't need a detailed understanding of airtightness or commissioning — but they do need to know exactly how to lay below-ground insulation efficiently and where extracare prevents failure later. A targeted, trade-specific course allows time to go into that level of detail; a general session doesn't.
What does a Coaction trade-specific training session cover?
Because every organisation and project is different, Coaction delivers all trade-specific training in-house, tailored to the client. A typical session has three parts:
<ol>
<li>Understanding building performance (context-setting)</li>
</ol>
<ul>
<li>Why buildings often fail to perform as intended</li>
<li>The common causes of performance gaps</li>
<li>What can be done to improve outcomes</li>
<li>An introduction to the client's chosen energy or performance standard (e.g. Passivhaus, EnerPHit, AECB)</li>
</ul>
<ol start="2">
<li>What it means for the site team</li>
</ol>
<ul>
<li>Changes to site processes and sequencing</li>
<li>Different construction approaches and expectations</li>
<li>The importance of coordination between trades</li>
<li>Site culture and quality-focused working practices</li>
</ul>
This section draws on Coaction's library of project case studies to show both good practice and real lessons learned, illustrating what success looks like on site
<ol start="3">
<li>Trade-specific guidance - Training then focuses on the client's selected trade and its specific challenges:</li>
</ol>
<ul>
<li>How performance requirements impact that trade's work</li>
<li>Why certain details need to be approached differently</li>
<li>Common on-site risks and mistakes for that trade</li>
<li>Examples of successful delivery from previous projects</li>
<li>Practical tips and proven solutions</li>
</ul>
Is a project review session included?
For projects needing a more tailored approach, Coaction can add an optional project review session covering:
<ul>
<li>The specified materials and processes, including sequencing options and their likelihood of success</li>
<li>Higher-risk areas: what skills are needed, whether better product options exist, and what benchmarking or auditing is worthwhile</li>
<li>Challenging interfaces between trades, and how responsibilities can be clarified</li>
</ul>
This session applies the training directly to a live project, so teams start on site already confident in what's expected of them and how to deliver it — including the cost and programme impact of different choices.
Which performance standards does this training support?
Coaction's trade-specific training supports teams working towards Passivhaus, EnerPHit, AECB, and other energy or quality performance standards, and is built around each organisation's own projects and challenges rather than delivered as a generic course.
<hr>
Frequently Asked Questions
What is trade-specific construction training? It's in-house training built around one trade (e.g. groundworks, insulation, airtightness) that explains how that trade's specific site decisions affect a building's overall energy performance and quality, rather than general oversight training for the whole team.
Who is trade-specific training for? Site teams and individual trades working on projects targeting higher energy or quality standards, such as Passivhaus, EnerPHit, or AECB.
How is it different from general site training? General training explains why performance matters across a project. Trade-specific training goes further, focusing on the exact risks, mistakes, and techniques relevant to one trade's own work.
Is the training delivered in-house? Yes! All of Coaction's trade-specific training is delivered in-house and tailored to the client's organisation, projects, and chosen performance standard.

Introduction to Fabric First Construction - High Wycombe

It was much more than I could have hoped for and I now feel much better equipped to carry on as a sole trading architect.

I would to say that the course was excellent, and very well presented by the team of tutors.

I thank the trainers for sharing their practical experience with us, sometimes that helps more than theory. – Gaia D’Abrosca (Allies and Morrison Architects)
