Verify the essentials
Check the current official installer list rather than relying only on a logo displayed on a supplier website.
- Current OZEV installer authorisation
- Relevant electrical registration and insurance
- Experience with comparable commercial sites
- Use of chargepoint models eligible under the scheme
- Written warranty and certification commitments
Ask for comparable quotations
Give each installer the same structured brief. Request an itemised response covering survey assumptions, hardware, installation, civils, load management, software, warranty, lead time, VAT and grant treatment.
Look beyond the installation day
Ask who supports faults, how software and connectivity are charged, what happens if the site expands and whether the proposed system can balance load. Ongoing costs are normally separate from eligible WCS installation expenditure.
Keep the shortlist small
Two or three well-matched quotations are usually easier to evaluate than a broad list of generic contacts. Relevant coverage, project size and capacity should shape the shortlist.
