Domestic electrical installation

Professional electrical installations, upgrades and safety solutions that keep your home compliant, efficient and protected.

Domestic electrical installation

Architectural lighting and exterior security

Lighting is a technical discipline. We focus on circuit load calculations and voltage drop analysis, so even complex dimming systems, including leading-edge and trailing-edge LED drivers, run without flicker or interference.

  • Security: high IP-rated outdoor fixtures that resist dust and water
  • Aesthetics: recessed spotlights and coffered ceiling LEDs calculated for the right lux levels

Kitchen engineering and high-load appliances

Kitchens are the most electrically dense rooms in a home. We install dedicated radial circuits for high-amperage appliances such as induction hobs and electric ovens.

  • Isolators: local, accessible isolation for every appliance in brushed chrome finishes
  • Diversity factors: we calculate maximum demand so your supply cable can run every appliance at once without overheating

Extensions, lofts and outbuildings

Expanding a property needs an audit of the existing total connected load. We don’t just tap into a circuit; we make sure the protective devices can handle the new demand.

For outbuildings we install steel wire armoured (SWA) sub-main cabling for mechanical protection, wiring everything from the origin to a new consumer unit with a safe, legal earthing arrangement such as a new TT system.

  • All loft and extension work is dead tested (continuity, insulation resistance and polarity) before a circuit is energised

Consumer units

The consumer unit is the heart of your electrical safety. We install only 18th Edition Amendment 2 compliant boards.

  • RCBO protection: each circuit is protected individually, so one fault disconnects only that circuit
  • Surge protection (SPD): Type 2 devices protect sensitive electronics and smart home systems
  • Arc fault detection (AFDD): recommended for high-risk premises such as HMOs and care homes

Earthing, bonding and shock prevention

Earthing is your primary defence. We verify your main earthing terminal and make sure incoming metal services (gas and water) have 10 mm² equipotential bonding, so a fault triggers the protective device instantly and prevents fatal shocks.

Certification and council compliance

Significant electrical work is a legal requirement under Part P of the Building Regulations.

  • EIC or Minor Works Certificate issued on completion
  • We notify your Local Authority Building Control, giving you the evidence you need when selling or insuring your property
