Electrical Contracting Northern Ireland

Electrical Contracting — Installation, Testing & Maintenance

Advanced Overwatch provides a full range of electrical contracting services for domestic, commercial and industrial clients across Northern Ireland. All work is carried out by City & Guilds 18th Edition qualified electricians and inspected by City & Guilds 2391 certified personnel, ensuring every installation meets the latest BS 7671 wiring regulations.

From routine testing and inspection through to complete electrical design and fit-out of commercial premises, we deliver reliable, compliant solutions backed by 24/7 emergency call-out support.

PAT Testing (Portable Appliance Testing)

Employers have a legal duty under the Electricity at Work Regulations 1989 and the Health and Safety at Work Act 1974 to ensure that electrical equipment used by employees is safe. PAT testing is the recognised method of demonstrating compliance:

  • What is tested — All portable and transportable electrical appliances, including computers, kettles, power tools, extension leads and phone chargers.
  • Testing frequency — Depends on the environment and equipment type. Offices typically require annual testing; construction sites and industrial settings require more frequent checks (3–6 months).
  • Certification — Each item tested receives a pass/fail label and a unique reference number. We provide a full register of all tested equipment along with formal certificates for your records and insurance purposes.
  • Failed items — Any equipment that fails testing is immediately labelled as unsafe and removed from service, with a written report detailing the fault.

Fixed Wire Testing (EICR)

An Electrical Installation Condition Report (EICR) is an inspection and test of the fixed electrical wiring in a building. It is a legal requirement in many circumstances:

  • Frequency — Commercial premises should be inspected at least every 5 years. Some sectors (e.g. swimming pools, petrol stations, construction sites) require more frequent testing.
  • Landlord obligations — Landlords in Northern Ireland have a duty to ensure electrical installations are safe for tenants. An up-to-date EICR provides evidence of compliance.
  • What is inspected — Consumer units, distribution boards, wiring, earthing, bonding, circuit protection devices and socket outlets. The inspection identifies any deterioration, damage, defects or non-compliance with current regulations.
  • Classification codes — Any defects found are categorised using codes C1 (danger present), C2 (potentially dangerous) and C3 (improvement recommended). We provide clear guidance on remedial action required.

Generator Installation & Maintenance

An uninterrupted power supply is critical for many businesses. Advanced Overwatch designs, installs and maintains standby generator systems to ensure your operations continue during mains power failure:

  • Standby generators — Diesel and gas-powered generators with automatic transfer switches (ATS) that activate within seconds of a mains failure.
  • UPS systems — Uninterruptible Power Supply units that provide instant battery backup for critical IT infrastructure, CCTV systems and access control, bridging the gap until the generator starts.
  • Planned maintenance — Regular servicing, load-bank testing and fuel management to ensure your generator starts reliably when needed.

EV Charging Point Installation

As electric vehicles become increasingly common, businesses and homeowners need reliable charging infrastructure. Advanced Overwatch installs EV charging points for commercial car parks, fleet depots, hotels, retail premises and residential properties. We handle the full process from electrical survey and load assessment through to installation, commissioning and OZEV grant applications where applicable.

Commercial Electrical Design & Fit-Out

We provide complete electrical design and installation services for new builds, refurbishments and commercial fit-outs. Our scope includes lighting design, power distribution, data cabling, security lighting, external and car park lighting, and integration with building management systems. We work with architects, contractors and project managers to deliver on time and within budget.
