Q: Do you offer full electrical installs for new builds?

Yes – we manage the full process: design, first and second fix, testing, and certification. We ensure every install meets BS 7671 standards.

If you’re running high-demand equipment like EV chargers, commercial kitchens or heavy machinery – most likely, yes. We’ll assess your load, apply to your DNO, and install safely.
