☀️ We’re hiring: Solar PV & Battery Technical Supervisor
📍 Chorley, Lancashire – Hybrid / Office-based
💷 £45,000–£55,000 basic salary
🕒 35 hours per week | Monday–Friday
📄 Permanent, full-time
🏢 Contact Solar, part of EDF
We’re looking for an experienced and appropriately qualified solar electrical professional to join our Completions team as a Solar PV & Battery Technical Supervisor.
This is an ideal opportunity for someone looking to move into an off-the-tools technical role, while still staying closely involved in live domestic solar PV and battery installations.
⚡ The role
You’ll be responsible for specific domestic solar PV and battery installations under the redeveloped MCS Installer Scheme.
You’ll assess the level of supervision required, monitor technical evidence while installations are taking place, and complete the final technical review before sign-off.
This is not simply a paperwork or administration role.
You’ll be expected to make clear technical decisions, challenge work that doesn’t meet the required standards, and refuse sign-off where an installation or its supporting evidence isn’t satisfactory.
Most supervision will be completed remotely through our job-management and installation-evidence systems. However, some installations may require closer supervision, direct contact with installation teams or an on-site technical inspection.
🔍 What you’ll be responsible for
- Act as an assigned Technical Supervisor for solar PV and battery installations, taking responsibility for safety, technical standards, quality and compliance.
- Determine and record the appropriate level of supervision for each installation, considering the work involved and the installation team’s competence and performance.
- Monitor live installation evidence and complete remote technical checks using photographs, documentation, telephone calls and video reviews.
- Require further evidence or corrective action where concerns are identified, escalating installations requiring closer supervision or a site inspection.
- Review electrical certification, test results, commissioning records, designs, DNO documentation and customer handover evidence.
- Confirm compliance with MCS Installation Standards, BS 7671, Building Regulations, manufacturer instructions and Contact Solar requirements.
- Approve installations for completion or refuse technical sign-off, raising clear non-conformances and remedial requirements where necessary.
- Review completed remedial work and formally close technical non-conformances once compliance has been demonstrated.
- Maintain accurate and auditable records of supervision decisions, technical involvement, installation reviews and sign-offs.
- Support MCS and Certification Body audits, identify recurring quality issues and provide technical feedback to installation partners and internal teams.
- Assist with technical queries, difficult installations and customer escalations, working closely with Completions, Installer Operations, Operational Compliance, Technical, Health & Safety and Customer Service.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
