New Builds & Developers

Commercial and residential electrical installations delivered with a clear understanding of site programmes and build schedules.

Hartwell Electrical Contractors work closely with developers, builders and project managers to deliver reliable electrical installations from first fix through to final handover.

Electrical Contractors for New Build Projects

Hartwell Electrical Contractors work on new build and development projects across Oxfordshire, supporting both residential and commercial schemes.

We understand the demands of working to programme, coordinating with multiple trades and maintaining momentum across build stages. Our approach is practical, organised and focused on keeping electrical works aligned with the wider construction schedule.

This page outlines how we typically support development projects and what you can expect when working with us on site.

A Practical, Site-Focused Approach

We are experienced working on live construction sites and understand the importance of sequencing, access and coordination.

  • Work planned to align with build programmes
  • Clear communication with site managers and contractors
  • Electrical works integrated with other trades
  • Strong focus on safety and compliance throughout

Electrical Installation Stages

First Fix

First fix work focuses on installing the core electrical infrastructure before walls, ceilings and finishes are completed.

  • Cable routes and containment systems
  • Distribution boards and sub-mains
  • Earthing and bonding
  • Coordination with other trades

Second Fix & Completion

At second fix stage, we complete, test and commission the electrical installation in line with project requirements.

  • Socket outlets, switches and accessories
  • Lighting and control systems
  • Emergency lighting and fire alarms
  • Final testing and certification

Working on Active Construction Sites

Our electricians are comfortable working within established site rules and procedures, coordinating closely with site managers to ensure work is carried out safely and efficiently.

This approach helps avoid delays, rework and clashes with other trades, supporting smoother project delivery from start to finish.

Testing, Certification & Handover

On completion, all electrical installations are fully tested and certified in accordance with current regulations.

We ensure developers receive clear, organised certification to support smooth project completion and sign-off.
