Higher Diploma in Renewable Energy Systems
Course Overview
The Higher Diploma in Renewable Energy Systems at the London School of Commerce and Technology (LSCT) is a 15 to 18 month Level 5 qualification taking technicians from foundation-level renewable energy into senior installer, design-engineer and small-project-management roles. Sitting in the Engineering & Science department, the diploma deepens technical design and commissioning skills while introducing project-management discipline aligned to UK Net Zero delivery.
You will lead a small project from feasibility to commissioning, present a design defence to a panel including a CIBSE-affiliated engineer, and produce a project portfolio defended in viva. Online, on-campus and distance routes are available from 2026.
Industry Context for the Higher Diploma in Renewable Energy Systems
UK renewables in 2026 sits in a period of sustained policy support and rising installer demand. The Boiler Upgrade Scheme and the continued PV pipeline have driven steady employer growth, MCS-certified installers face heavier scrutiny on design and commissioning paperwork, and CIBSE-led design standards have become the default reference for senior practitioner work. The Higher Diploma in Renewable Energy Systems is sequenced against that reality, with PVSyst design exercises, heat-pump calculations and commissioning documentation treated as core rather than supplementary. Content is reviewed each year against IET wiring guidance and live MCS standards.
Key Features
- Level 5 UK Higher Diploma with content reviewed by IET, CIBSE and ECITB-affiliated practitioners.
- Three flexible study modes with regional practical workshops and shared design software access.
- Small project lead — students take a domestic-scale install from feasibility to commissioning.
- Design module using PVSyst for PV and MCS heat-pump design tools.
- Project management strand covering CDM 2015 and APM-aligned discipline for small renewable jobs.
What You Will Learn on the Higher Diploma in Renewable Energy Systems
The diploma is structured around what a senior renewable-energy technician must do unsupervised: scope a job, design the system, manage the install, commission safely, and document for the customer and the regulator. You will graduate able to lead a domestic or small-commercial installation end to end. Assessment is portfolio-led — students submit weekly PVSyst exercises, a heat-loss survey, a written G99 application, a CDM 2015 site plan and a final commissioning dossier defended at panel review by working CIBSE-affiliated design engineers.
- Advanced PV design and PVSyst modelling
- Heat pump design for domestic and small commercial
- Battery storage and inverter selection
- Grid connection — G98, G99 and DNO liaison
- Commissioning, testing and handover documentation
- MCS certification process and standards
- CDM 2015 and small-project H&S leadership
- Project management for renewable installations
- Customer journey and post-install service
Who This Course Is For
- Renewable-energy technicians stepping into design or supervisor roles.
- Electricians and plumbers deepening renewable-installation scope.
- HVAC engineers crossing into heat-pump design.
- Career switchers with prior trade experience entering the energy transition.
Career Pathways
Graduates work across UK installers, energy consultancies, building-services firms and small renewable contractors, with consistent demand from the heat-pump rollout and the UK PV pipeline. Typical destinations include:
- Renewable Energy Technician progressing to Senior Installer
- Solar Design Engineer
- Heat Pump Design Engineer
- Commissioning Engineer
- Site Engineer (renewables)
- Energy Consultant (junior)
The Higher Diploma articulates into a BEng or BSc in Renewable Energy, Electrical Engineering or related, and supports MCS-certification pathways for installer firms. Graduates typically progress into senior installer and design-engineer roles within months of completion, with London-based renewable engineer day rates sitting in the upper band of the building-services trades market and progression accelerating once a defended project portfolio is held.
Entry Requirements
- An Advanced Diploma (Level 5), HND, Foundation Degree, or equivalent prior study in engineering, renewable energy or a related field.
- Three years' relevant work experience as an electrician, plumber, HVAC engineer or renewable-installer technician considered in lieu of academic prerequisites (mature applicants).
- English language: IELTS 6.0 overall (no band below 5.5) for non-native English speakers.
- A personal statement plus one academic or professional reference, ideally from an installer firm or senior engineer.
Why Study at LSCT
The London School of Commerce and Technology (LSCT) is a specialist higher-education provider based in central London and part of Harold International College. We teach in small cohorts so every student is visible to their tutor, run a single intake schedule that students can rely on, and partner with UK professional bodies so qualifications carry weight with employers. London puts Whitehall, the City, Silicon Roundabout, the Royal Courts of Justice, the West End and the NHS estate within a short tube ride of every classroom — and our students use that proximity in their projects, placements and graduate job hunts. Senior renewable-energy students get design reviews from working CIBSE-affiliated engineers active in the UK heat-pump rollout.
