PV Surveys
Alongside the core commercial electrical scope, FLD delivers independent solar PV surveys for building owners, managing agents and incoming tenants. A PV survey covers:
- Structural feasibility of the roof for a commercial rooftop solar array
- Incoming supply capacity and spare headroom against proposed generation
- DNO export-capacity view and indicative G99 Type A pathway with NGED
- Existing distribution board, switchgear and earthing assessment for solar integration
- Generation modelling from PVGIS data against the building's half-hourly consumption
- Written survey report with sized system recommendation, indicative capex and simple payback
PV surveys are delivered as a standalone commission or bundled into the full electrical design-and-install scope.
Emergency call-out
We run a responsive emergency call-out service for commercial clients across SA, CF, NP and LD postcodes, with standard attendance within four working hours.
Our process
- 1Site survey
A named FLD engineer visits your site, measures the roof or installation zone, inspects the incoming supply and verifies load, structural integrity and orientation. For commercial sites we run a full discovery including half-hourly consumption data where available.
- 2Design and proposal
We produce a scaled layout, generation model using PVGIS data, financial model with simple and post-tax payback, DNO G99 or G98 notification pack where relevant, and a fixed-price quotation. Every proposal names the exact panels, inverters and mounting system.
- 3DNO and planning
We handle NGED G99 Type A applications for commercial systems, G98 notifications for domestic, and any permitted development confirmation or full planning submissions required for listed buildings or conservation areas.
- 4Install and commission
FLD directly-employed engineers install under a single NICEIC Approved Contractor sign-off. Commissioning includes BS 7671 testing, SolarEdge monitoring portal setup, MCS certification where applicable, and handover of all documentation.
- 5Aftercare
Insurance-backed NICEIC warranty, 25-to-30-year panel performance warranty from the tier-1 manufacturer, 12-year SolarEdge inverter warranty, and ongoing O and M support including remote performance monitoring.
