FAQs
What qualifies as a “complex” electrical installation, and do you handle both residential and commercial projects in Duff?
A complex installation typically involves advanced system design, high-capacity service panels, multiple sub-panels, integrated smart-control networks, backup generators, renewable-energy tie-ins, or specialised industrial machinery. We service both residential and commercial/industrial locations in Duff. Our NIC-EIC certified electricians create detailed load calculations, single-line diagrams, and phased work plans to ensure every component—from heavy-duty busbars to low-voltage control wiring—meets safety, performance, and future-expansion requirements.
Are your electricians licensed and insured to work in Duff?
Yes. Every field technician holds a current state electrical licence and is registered with the local authority serving Duff. We carry £5 million in public liability insurance, £10 million in employers’ liability, and professional indemnity cover. Copies of licences, insurance certificates, and risk assessments are provided before work commences to give clients full peace of mind.
How do you troubleshoot electrical faults without shutting down my entire facility?
We employ live-testing methodologies such as thermal imaging, power-quality analysers, and selective isolation so only the affected circuits are de-energised. Our portable load banks allow us to simulate real-world demand, while circuit identifiers and harmonic analysers pinpoint intermittent faults. This targeted approach keeps critical operations running while we locate and remedy the problem safely.
Which codes and standards do you follow for installations and repairs in Duff?
All work complies with the current edition of BS 7671 (IET Wiring Regulations), Part P of the Building Regulations, and Electricity at Work Regulations 1989. For commercial clients, we also align with IEC 60364, EN 50110, and manufacturer-specific standards for switchgear and control panels. Upon completion, you receive an Electrical Installation Certificate (EIC) or Minor Works Certificate plus test results for earth loop impedance, RCD trip times, insulation resistance, and functional verification.
Do you offer 24/7 emergency repair services, and how quickly can you respond in Duff?
Yes. Our emergency response team is on call 24 hours a day, 365 days a year. For addresses within Duff and surrounding villages we target a 60-minute arrival window; in rural areas we aim for 90 minutes. Vans are stocked with common breakers, RCDs, cable types, glands, and portable distribution boards so most faults can be rectified on the first visit.
How are complex installations or major repairs priced, and what warranties do you provide?
We begin with a free site survey to assess scope, compliance requirements, and any access constraints. You receive a fixed-price quotation broken down by labour, materials, specialist plant, and certification fees. For projects over £10,000 we offer staged payments linked to milestones. All workmanship is guaranteed for 5 years, and supplied components carry the manufacturer’s warranty—typically 12 to 25 years for switchgear and PV equipment. Annual maintenance packages are available to extend coverage and maximise system lifespan.
