Customer First
Verified testimonials from homeowners, facilities managers, and project directors — published with client permission and reflecting the complete project experience from first survey through to the final handover certificate and post-installation check.
Reviews in this channel are collected at handover or submitted unsolicited — not curated from a platform at the moment of payment. Where clients have described specific aspects of delivery such as programme adherence, documentation quality, site behaviour, or responsiveness, those details are retained in the published text rather than averaged into a rating score.
Feedback spans residential EV installations and domestic rewires through to multi-phase commercial fit-outs and industrial commissioning programmes. The range reflects Nexgen's cross-sector capability — and the consistency of that feedback across very different project types and client profiles is the authentic measure of our operating standards.
Residential reviews covering rewires, EV charging, consumer unit upgrades, and smart home integration across all property types.
Facilities managers and project directors on Cat B fit-outs, retail refurbishments, and multi-site programme delivery.
Feedback covering the whole service — survey, installation, programme, documentation, and post-handover support.
