Electrical Design
Electrical design services are essential for ensuring that buildings are powered safely, efficiently, and in compliance with UK regulations. At Focus 360 Energy, we deliver expert electrical design and engineering tailored to both domestic and commercial environments. Our solutions range from basic power distribution to complex lighting, control systems, and renewable integrations. Every electrical design engineer in our team works closely with architects and contractors to ensure the electrical design integrates seamlessly with mechanical, structural, and sustainability requirements, delivering a robust and compliant system.
What are Electrical Design Services?
Electrical design services cover the full planning, calculation, and detailed specification of all electrical systems within a building. This encompasses safe and stable power distribution, efficient lighting design (including emergency systems), fire alarm systems, security systems, and renewable technology integration. Our electrical design and engineering approach ensures that all installations meet required safety and performance standards, specifically complying with Part P of Building Regulations and BS 7671 (IET Wiring Regulations). This detailed planning is crucial for long-term safety, efficiency, and regulatory approval.
What Does the Electrical Design Service Involve?
Load Assessments and Circuit Calculations: Precise calculation of maximum demand, cable sizing, and protective device specification for safe power distribution.
Lighting Design and Emergency Systems: Detailed planning of general and emergency lighting layouts to meet aesthetic, lux level, and safety standards.
Safety and Life Systems Design: Specification of fire alarms, smoke detection, security systems, and earthing/bonding requirements.
Renewable Energy Integration: Design and specification for low-carbon technologies, including solar PV systems, EV charging points, and battery storage.
Compliance Verification: Ensuring the design adheres strictly to BS 7671 (IET Wiring Regulations), Part P of Building Regulations, and other relevant safety codes.
Why Electrical Design Matters
Expert electrical design is a non-negotiable requirement for ensuring the safety and regulatory compliance of any modern construction project. Without accurate load assessments and circuit calculations, buildings risk overloaded systems, fire hazards, and immediate non-compliance with Building Control. Furthermore, professional design enables long-term efficiency, optimising the performance of lighting and renewable systems to reduce operational costs and meet sustainability goals. By integrating early, we prevent costly clashes and guarantee a future-proof, high-performing electrical backbone for the entire asset.
How Our Accredited Assessors Support You
Our electrical design engineers are highly experienced and fully up-to-date with the latest editions of BS 7671. We specialise in delivering integrated M&E solutions by working directly with our in-house mechanical design team. This coordination is key: we align power requirements for HVAC systems (like heat pumps and ventilation) with the available grid supply and renewable sources. This coordinated approach eliminates technical conflicts, ensures optimal energy efficiency across both mechanical and electrical domains, and streamlines the documentation required for technical submission and compliance checks.
