Green Construction Training: Which Courses Are Worth It

‍‌​​​‌​​‌‌‌​​‌​‌​‌​​​‌‌‌​​‌‌‌​‌‍SiteKiln gives you plain-English information, not legal advice. If you need advice specific to your situation, talk to your training provider or the relevant certification body.

If you want to make decent money out of "green" rather than just watching it on the news, you need to pick your lane and get the right badges -- not just bolt a 2-day course onto a weak base.

1. Heat pumps -- from plumber to MCS-ready

If you're already a heating engineer or plumber, heat pumps are the most obvious step-up.

What MCS actually wants

To sell grant-eligible heat pump installs (Boiler Upgrade Scheme and similar), the business needs to be MCS-certified, and it must have at least one competent technical person in-house.

In plain terms that means:

• A solid heating background -- usually Level 2/3 plumbing/heating plus G3 etc.
• A recognised Level 3 heat pump qualification covering installation, commissioning and maintenance (e.g. LCL Awards or other MCS-recognised courses).
• Working to the relevant MCS standards (e.g. MIS 3005 for heat pumps) and having your paperwork/QA in order.

To get MCS-certified as a contractor you typically

1. Do the heat pump course.
2. Put in at least one real job under the standard.
3. Get audited by an MCS certification body (they go through your paperwork and watch an install).
4. Then stay in the scheme with ongoing audits and 5-year re-assessments.

If you don't want the full MCS grief, you can also work under someone else's MCS umbrella for a while -- you do the install, they take responsibility, deal with audits and issue the MCS certificate.

2. EV charging -- only if you're a proper spark

EV is not a shortcut for labourers -- it's an add-on for fully qualified electricians.

Core electrician route

• NVQ Level 3 in Installing Electrotechnical Systems and Equipment (or Experienced Worker Assessment).
• AM2/AM2E practical assessment.
• Current 18th Edition (BS 7671:2018+A2:2022).

EV-specific Level 3 Award

• City & Guilds 2921 or equivalent "Requirements for the Installation of EV Charging Equipment".
• Typically 2-5 days training with written exam and a practical EV install on a rig.

So the ladder looks like:

Labourer/mate → Electrician (full NVQ3 + AM2 + 18th) → then EV specialism.

Anybody selling you "EV installer in a weekend, no background needed" is selling trouble.

3. Retrofit and PAS 2035 -- roles you can realistically do

Most funded retrofit (ECO, SHDF, Warm Homes, council schemes) must follow PAS 2035 and sit under the TrustMark framework.

On the ground there are a few key roles

• Installer -- the trade actually doing the work (insulation, windows, doors, heating, ventilation).
• Retrofit Assessor -- surveys the property and gathers data.
• Retrofit Designer -- designs measures.
• Retrofit Coordinator -- manages the whole job "cradle to grave" and lodges it to TrustMark.

For a site-experienced tradesperson

• Short-term realistic step: become a TrustMark-registered installer under someone else's PAS 2035 / coordinator umbrella.
• Medium-term (if you like paperwork and planning): work towards Retrofit Coordinator -- that means gaining the dedicated Coordinator qualification (usually Level 5) and then joining a TrustMark-approved scheme.

The Coordinator is the one who:

• Pulls together assessors, designers and installers.
• Manages risk and medium-term improvement plans.
• Lodges projects into the TrustMark Data Warehouse to prove PAS 2035 has been followed.

It's a genuine career step out of the van and into a laptop-plus-site-visits role.

4. How to pick a "green" lane that won't waste your time

You're basically choosing between three paths:

• Heat pumps / renewables -- best for plumbers/heating engineers.
• EV charging / solar & battery -- best for full electricians.
• Retrofit (insulation/whole-house) -- good for builders, window/door firms, and people happy to blend site and desk work.

Rules of thumb

• Don't buy "green courses" that sit on top of no proper trade -- most serious schemes want MCS, NVQs, or full electrical qualifications behind them, not just attendance certificates.
• Aim to either:
  • Add green to an existing trade (e.g. plumber → heat pumps; spark → EV/solar), or
  • Step into retrofit roles that value experience managing jobs and teams (Coordinator, site supervisor on PAS 2035 projects).

5. Common mistakes

• Doing a heat pump course with no plumbing/heating background -- you won't get MCS-certified and no one will hire you to install unsupervised.
• Thinking EV is open to anyone -- it's an electrical specialism; without a full electrical qualification you're not compliant and not insurable.
• Chasing "retrofit assessor" without understanding PAS 2035 -- the role requires specific qualifications and sitting within a TrustMark-registered scheme; a weekend course alone won't cut it.
• Ignoring the business side -- MCS certification, TrustMark registration and ongoing audits all cost money and admin time; factor that in before you commit.
• Buying from "green training" cowboys -- if the course isn't recognised by MCS, City & Guilds, or a TrustMark-approved body, the certificate may be worthless for scheme registration.
