RJW Electrical
1st & 2nd Fix Electrical Installations
RJW Electrical plans and installs first-fix and second-fix electrical systems for domestic, commercial and industrial projects across the Midlands. Qualified engineers coordinate wiring, containment, accessories and final connections to deliver installations aligned with current safety and wiring requirements.
Experienced, Accredited Electrical Installation Specialists
First-fix electrical installation establishes the concealed infrastructure: cable routes, back boxes, containment and provisions for equipment are positioned before walls and ceilings are completed. Second-fix electrical work follows, adding switches, sockets, luminaires, connection units and other accessories, then completing final connections and checks.
RJW Electrical applies this staged approach to alterations, new installations and project-specific wiring requirements. The work can be coordinated with other trades and construction phases, helping ensure that installed systems match the design, intended use and practical demands of the building.
With 20 years’ experience, RJW Electrical’s work is supported by NAPIT membership, TrustMark scheme membership and registration with the Electrical Safety Register. Fully qualified engineers work to current wiring standards, with appropriate inspection and documentation forming part of a properly controlled installation.
How the Installation Process Is Managed
A well-managed electrical installation moves from an initial enquiry to defined requirements, site preparation, installation, verification and handover. The following stages show how information, decisions and quality checks are managed from the first discussion through completion.
- 01
Initial Enquiry and Requirements
The process begins with a discussion of the proposed installation or alteration, including the building type, intended use, equipment requirements and any known constraints. This establishes the scope for a suitable quotation and identifies information needed before work is planned.
- 02
Site Assessment and Scope Definition
Relevant site conditions are reviewed before installation starts. Existing electrical systems, access, cable routes, containment requirements and coordination with other trades are considered so that the work can be defined accurately.
- 03
Installation Planning
The agreed scope is translated into a practical installation plan covering materials, wiring routes, accessories, equipment connections and the sequence of work. Preparation is coordinated with the project programme and the condition of the building.
- 04
First-Fix Installation
During first fix, concealed cables, back boxes, containment and other infrastructure are installed in the agreed positions. Routes and provisions are set out to suit the design and to allow the later connection of electrical accessories and equipment.
- 05
Second-Fix and Alterations
Once the relevant construction work allows, second-fix components such as switches, sockets, luminaires and connection units are fitted. Alterations to existing circuits or additional connections are completed as defined in the agreed scope.
- 06
Inspection, Testing and Handover
Completed work is inspected and tested in accordance with current wiring requirements. Relevant results and installation documentation are prepared, with any outstanding points identified and explained as part of the handover.
Qualified & Compliant
Fully insured, DBS-checked engineers apply current wiring regulations, with inspection records supporting safe, accountable installations for domestic and commercial clients.
Questions About 1st & 2nd Fix Electrical Installations
What preparation is needed before a first-fix electrical installation begins?
Before work starts, confirm drawings, equipment positions, access arrangements, existing circuit information and responsibilities between trades. This helps coordinate first-fix routes, second-fix accessories, testing and completion records for the site.
What happens if testing identifies an issue during an electrical installation?
If testing identifies an issue, the affected circuit or installation stage is recorded, investigated and corrected before completion. Further verification confirms the remedial work meets applicable safety requirements and documentation.
How much disruption does an electrical installation involve?
Disruption varies by installation scope and building use. Phased work can help coordinate access, protect finished areas and limit interference with occupants, while keeping each installation stage organised and documented.
What records should accompany a completed electrical installation?
Completed installations should include the appropriate electrical installation certificate, circuit schedules, test results, updated drawings where applicable, and operating information, giving owners evidence of compliance and guidance for future alterations.
How are design changes handled during an electrical installation?
Design changes should be reviewed against circuit capacity, cable routes, equipment positions, regulations and programme requirements. Approved revisions are recorded before affected work proceeds, with drawings and schedules updated accordingly.
Clear Communication and Careful Installation Standards
For installations and alterations, clear communication confirms the scope, access arrangements, programme and responsibilities before work begins. This gives clients and other trades a shared reference for decisions and site coordination.
Dependable attendance supports planned progress, while careful workmanship delivers secure connections and a tidy finish around accessories and equipment. Completed work is checked against agreed requirements before handover.
Clear Project Communication
Key decisions, requirements and site information are explained in plain terms so clients, contractors and other trades can work from the same brief.
Considered Project Sequencing
First-fix and second-fix activities are planned in relation to construction phases, helping electrical work fit logically within the wider installation.
Controlled Workmanship
Cables, connections and accessories are installed with attention to correct positioning, secure fitting and a professional finish.
Safety-led Practice
Electrical work is approached with current wiring requirements in mind, supporting responsible installation decisions from initial planning through completion.
Clear Completion Records
Inspection information and relevant installation records provide a useful reference for completed work and the project handover.
