I note City and Guilds have recently introduced two new qualifications into their electrical installation portfolio. Small Solar PV Systems (2922) and Small Electrical Energy Storage Systems (2923). The qualifications were developed with TESP (under their Electrician Plus scheme) and others and intended for qualified and experienced electricians. On successful completion, they can apply to have the qualifications added to their ECS card.
The training centre I work for on a part-time basis has fielded many enquiries from interest contractors wishing to embrace work in this area. Unfortunately, the centre has had to turn many prospective candidates away as they did not fulfil the entry requirements. Candidates must have achieved a recognised electrical installation NVQ Level 3 qualification no more than five years prior to starting either of the two new qualifications.
The centre was prepared to make substantial investment to erect training rigs etc but they are shelving that for the moment.
I guess I understand the rationale to limit entry to qualified and experienced electricians but it might result in fewer centres offering the qualification.
