🚗 EV Charging Design

EV Charging Design for Homes, Apartments and Car Parks

Planning EV charge points starts with the supply. We check whether your existing supply and earthing can take the extra load, then design a charging installation that works within it, whether that's one charger on a driveway or charging across a whole development or car park.

What's included

  • Supply capacity and maximum demand checks that take account of your existing load
  • Load management and load-balancing strategies, so chargers share the capacity you have
  • Charger numbers and layout for apartment blocks, workplaces and car parks
  • Cable sizing, routing, protective devices and RCD selection to BS 7671 Section 722
  • Earthing design, including PME considerations and where a separate earth electrode may be needed
  • Designs that follow the IET Code of Practice for Electric Vehicle Charging Equipment Installation
  • The technical details your installer needs for the NIE Networks pre-installation application
⚡ NIE Supply Applications

NIE Networks Supply Applications, Handled for You

Whether you're building new homes, converting a property or adding load to a business, getting the right supply from NIE Networks starts with an accurate maximum demand figure. We calculate it, prepare and submit the application with its supporting information, and liaise with NIE Networks until your connection offer arrives.

What's included

  • Maximum demand and diversity calculations to set the Maximum Import Capacity (kVA) you need
  • New supply applications for developments, conversions and commercial premises
  • Load change applications for increased supplies, including single-phase to three-phase upgrades
  • Load details, appliance schedules and supporting drawings prepared for the application
  • Meter position and incoming supply arrangements coordinated with your electrical design
  • Liaison with NIE Networks through to your connection offer, and help understanding it, including dual offers where an Independent Connection Provider is an option
🔑 Landlord & HMO Compliance

Landlord & HMO Electrical Compliance in Northern Ireland

Private landlords in Northern Ireland must now have the fixed electrical installation inspected and tested by a qualified person at least every five years, and HMOs need the right electrical and fire safety certificates to be licensed. We coordinate the inspections, review what they find and specify what needs fixing, so you know exactly where you stand.

What's included

  • EICRs arranged with a qualified inspector, then reviewed by us, with C1, C2 and FI observations explained in plain English
  • Remedial work specified to BS 7671, so your contractor can quote and fix to a clear scope
  • Fire detection and alarm compliance review against BS 5839-6 (or BS 5839-1 where applicable): grade, category, coverage and certification
  • Emergency lighting compliance review against BS 5266 where it is required
  • A documentation pack that organises reports, certificates and remedial evidence for tenants, the council and HMO licence applications
  • A schedule showing when each inspection and certificate falls due

The rules in Northern Ireland

Private tenancies: The Electrical Safety Standards for Private Tenancies Regulations (Northern Ireland) 2024, introduced under the Private Tenancies Act (Northern Ireland) 2022, have applied since 1 April 2025. Landlords must have the electrical installation inspected and tested by a qualified person at least every five years, give the report to tenants (within 28 days, or before a new tenant moves in), provide it to the council within 7 days if asked, and complete any remedial or further investigation work within 28 days or sooner if the report says so.

HMOs: Houses in multiple occupation are licensed under the Houses in Multiple Occupation Act (Northern Ireland) 2016 through the NI HMO Unit, and remain under that scheme rather than the private tenancy regulations. A licence application must include supporting documents such as a current EICR (one showing C1 or C2 faults is treated as non-compliant), fire detection and alarm certificates, emergency lighting certificates where applicable and a fire risk assessment.

General information only, not legal advice. Your duties depend on your property and tenancy. See also our compliance legislation guide.

☀️ Solar PV & Battery Storage

Solar PV and Battery Storage Design

Solar and battery systems need to fit the supply, the building and the regulations. We design the electrical side of the system for homes, apartment blocks and commercial and industrial sites, and prepare the technical details for your grid connection application, so your installer can build from a clear specification.

What's included

  • System sizing and layout for roofs, ground arrays and car ports
  • AC and DC cable sizing, protective devices and isolation
  • Inverter and battery integration, including backup and islanding arrangements where required
  • Earthing and protection design to BS 7671 (Section 712 and the battery storage requirements) in Northern Ireland, or I.S. 10101 in the Republic of Ireland
  • Maximum demand and supply capacity checks with your existing load
  • Technical details for connection applications to NIE Networks or ESB Networks
