Who are our electrical services for?
Homeowners
Whether you need a full rewire, consumer unit upgrade, additional sockets or outdoor lighting — we handle all domestic electrical work. Every job is NICEIC certified and compliant with Part P Building Regulations.
Commercial & industrial
Offices, retail units, warehouses and factories need reliable electrical infrastructure. We handle new fit-outs, distribution board upgrades, three-phase installations, emergency lighting and periodic testing for compliance.
Landlords & property managers
Electrical safety is a legal requirement for rental properties. We carry out Electrical Installation Condition Reports (EICRs), remedial work and consumer unit upgrades to keep your properties compliant and your tenants safe.
Planned electrical installation, inspection and upgrade work
Omni3 focuses on planned electrical contracting — new installations, scheduled inspections, upgrade work and electrical projects that require a qualified, accredited contractor rather than a general handyman.

How we work
Consultation & assessment
We visit your property, assess the existing electrical installation, discuss your requirements and identify any compliance issues. For EICRs, we carry out a full inspection and testing schedule.
Design & quotation
We design the electrical layout, specify materials and provide a clear, itemised quote. For larger projects, we produce circuit schedules and distribution board layouts.
Installation
All work is carried out by Omni3, an NICEIC Approved Contractor, to BS 7671 (18th Edition Wiring Regulations). We work cleanly, communicate progress and minimise disruption to your home or business.
Testing & certification
Every installation is fully tested and certified. You receive an Electrical Installation Certificate (EIC) or Minor Works Certificate as appropriate. EICRs include a detailed condition report with coding.
Handover
We walk you through the completed work, explain your consumer unit, hand over all certificates and answer any questions. Documentation is provided for your records and insurance.
What affects electrical service costs?
Scope of work
A single socket addition is straightforward. A full house rewire involves lifting floorboards, chasing walls and replacing every circuit. The scope determines labour time and material costs.
Property age & condition
Older properties often have outdated wiring, asbestos, lead pipes near cables or non-standard installations that require additional work to bring up to current standards.
Consumer unit specification
A basic consumer unit upgrade is relatively affordable. Dual RCD boards, AFDD protection and surge protection devices add cost but improve safety significantly.
Access & disruption
Easy access to cable routes keeps costs down. Properties with solid walls, concrete floors or limited loft space require more labour for cable routing and containment.
Certification requirements
All notifiable work requires Building Regulations notification and certification. EICRs require a full inspection schedule. Commercial properties may need more extensive testing.
Emergency vs planned
Planned work is more cost-effective. Emergency callouts for fault finding and urgent repairs carry a premium due to response time and out-of-hours availability.
Every property and project is different
Pricing depends on the condition of the existing installation, the scope of work and testing requirements. Contact Omni3 for a fixed, itemised quotation.
Request a QuotationCommon electrical mistakes
Using an unqualified electrician
Electrical work carried out by unqualified individuals is dangerous, non-compliant and often uninsurable. Always use an NICEIC approved contractor who can certify their work and notify Building Control.
Ignoring an old consumer unit
Old fuse boards with rewirable fuses offer no RCD protection. A fault that would trip a modern board could cause a fire or electrocution with an old one. Upgrading your consumer unit is one of the most important safety improvements you can make.
Skipping periodic testing
Electrical installations deteriorate over time. Connections loosen, insulation degrades and circuits become overloaded. Regular EICRs catch problems before they become dangerous. Landlords are legally required to test every 5 years.
Overloading circuits
Adding appliances, EV chargers or electric heating to circuits not designed for the load causes overheating and fire risk. We assess your supply capacity and upgrade circuits where needed.
