Electrical Engineering Services
Comprehensive electrical building services design — compliant, coordinated and buildable — from incoming supply and LV infrastructure through to life-safety and specialist systems.
Get in touchElectrical design that works on site, not just on paper
JBSE Consulting Engineers provides full electrical building services design across commercial, residential, industrial and public-sector projects. That covers the incoming supply and LV distribution strategy, small power and lighting, life-safety and specialist systems, and the calculations, drawings and specifications that turn the design intent into information a contractor can price and install.
What shapes the output is a time-served, practical electrical background gained before moving into consultancy. Having installed, tested and commissioned these systems, the design is developed with containment routes, switchroom access, terminations and installation sequence already in mind — so potential site issues are identified at design stage rather than raised as RFIs mid-programme.
The result is a coordinated electrical package: compliant with BS 7671 and the relevant standards, coordinated with the mechanical, public health and structural design, and buildable within the programme and budget the project is working to.
Complete electrical engineering capabilities
Every element of the electrical package, from the distribution strategy through to construction-stage support — grouped by the stage of the project each belongs to.
Design & infrastructure
Electrical building services design
Full electrical design from concept through technical design, coordinated with the architecture, structure and other building services.
LV distribution & infrastructure design
Incoming supply arrangements, switchgear, sub-mains and final circuit distribution sized on assessed load and diversity.
Lighting & emergency lighting design
Internal and external lighting schemes designed to the relevant guidance, with emergency lighting coverage and duration to suit the escape strategy.
Life-safety & specialist systems
Fire alarm & life-safety systems
Detection and alarm category selection, zoning and interfaces with ventilation, access control and other life-safety plant.
Data, security, access control & communications
Structured cabling, containment, CCTV, access control and communications infrastructure designed alongside the electrical distribution.
Earthing, bonding & lightning protection
Earthing arrangements, main and supplementary bonding, and lightning protection assessed against the risk and the site conditions.
Analysis & delivery
Calculations, protection coordination & cable sizing
Load assessments, cable sizing, voltage drop, fault level, protective device selection and discrimination — recorded and traceable.
Surveys, condition assessments & technical reports
Site surveys of existing installations, condition appraisals and technical reports to establish what is there before design decisions are made.
Specifications, tender documentation & design reviews
Drawings, schedules and specifications written to be priced accurately, plus independent review of contractor and specialist design submissions.
Site inspections, testing reviews & construction support
Progress inspections, review of test results and certification, technical queries and installation support through to commissioning and handover.
Designed to the codes your installation is certified against
Electrical designs are developed to BS 7671 and the relevant BS EN standards, with CIBSE guidance and the Building Regulations applied where they govern lighting, energy performance and life-safety provision. Distribution network operator and manufacturer requirements are coordinated alongside, and the electrical design is developed in step with the mechanical, public health and structural packages so plant loads, service routes and builder's work are agreed rather than assumed.
