01 · Service overview

What Electrical Appliance Installation Can Include

The correct installation depends on the appliance rating, connection method, available circuit, local isolation and the manufacturer’s electrical requirements.

01

New Fixed Appliance Installation

A new fixed appliance can be connected after the existing supply, protective device, cable and isolation have been checked for the proposed load.

02

Kitchen Appliance Electrical Installation

Ovens, hobs, cookers and other fixed kitchen appliances need a connection method and electrical supply that match the appliance instructions.

03

Existing Supply Assessment

Where an existing circuit is being reused, its condition, capacity, isolation and protection should be checked before the appliance is connected.

A new appliance should not be connected simply because the existing outlet appears to fit. The appliance rating, circuit capacity, connection point and local isolation should be checked first. If the existing supply shows tripping, heat damage or another electrical fault, arrange electrical fault finding before appliance installation.
02 · Appliance types and connection requirements

Fixed Appliances That Need the Right Electrical Connection

The installation method varies with the appliance, its electrical rating and the existing supply. The connection is confirmed after the manufacturer requirements, circuit and isolation have been checked.

01

Built-In Electric Ovens

Built-in ovens may use an existing suitable connection point or require circuit alterations where the new appliance has different electrical requirements.

02

Electric and Induction Hobs

Electric and induction hobs can place a significant load on the circuit, so the appliance rating and existing supply need to be checked before connection.

03

Electric Cookers

Cooker installation should match the manufacturer’s connection method, circuit capacity, protective device and accessible local isolation.

04

Cooker Hoods and Fixed Extractors

Fixed cooker hoods and extractors need a suitable electrical connection point and isolation arrangement within the agreed installation scope.

05

Integrated Electrical Appliances

Integrated appliances need the electrical connection and isolation to remain suitable and accessible once the appliance is fitted into the finished kitchen layout.

06

Other Fixed Electrical Equipment

Other fixed electrical equipment can be assessed where the appliance rating, connection method and existing electrical installation are suitable for the proposed work.

The appliance model is only one part of the decision

Rating and Supply Matter More Than the Connection Point Alone

The assessment considers the appliance rating, connection method, existing cable, protective device and local isolation. A higher-load appliance may require a consumer unit assessment, a dedicated circuit through our electrical contractor service, or wiring improvements before the appliance is connected.

03 · Electrical supply and installation safety

How the Appliance and Electrical Supply Are Matched

A fixed appliance should be connected only after its electrical requirements have been compared with the existing circuit, protective device, cable and isolation arrangement.

Rating

Match the Appliance Rating to the Supply

The appliance rating and manufacturer data are checked against the available electrical supply before the final connection method is confirmed.

Circuit

Confirm Circuit Capacity

The existing cable and protective device need to suit the appliance load and the way the circuit is installed.

Isolation

Provide Suitable Local Isolation

The connection should include an appropriate and accessible means of isolation where required by the appliance and installation arrangement.

Instructions

Follow the Manufacturer Requirements

The appliance instructions help determine the connection method, electrical rating, isolation and any specific installation requirements.

Electrical design note

The appliance rating does not by itself confirm that an existing circuit is suitable. The manufacturer’s electrical data, cable, protective device, connection method and local installation conditions must all be checked.

Electrical work in dwellings may fall within Approved Document P, while the certificate provided after qualifying work depends on the electrical installation work completed.
04 · From appliance details to handover

How Electrical Appliance Installation Is Planned

The process starts with the appliance details and existing electrical connection, then finishes with the required electrical checks and a clear handover.

  1. 01

    Appliance Details and Site Check

    We confirm the appliance type, make and model where available, electrical rating, proposed position and the existing connection point.

  2. 02

    Electrical Supply Assessment

    The circuit, cable, protective device, isolation and manufacturer connection requirements are reviewed before installation.

  3. 03

    Installation and Connection

    The agreed electrical work is completed and the appliance is connected using the confirmed connection and isolation arrangement.

  4. 04

    Testing and Handover

    The completed electrical work is checked and tested as required, and the appliance connection and isolation are confirmed before handover.

Before the appointment

Prepare the Details That Affect the Installation

Basic appliance and connection details help identify what needs to be checked before the final installation scope is confirmed.

  • Provide the appliance make, model and electrical rating
  • Send a photo of the existing connection point or outlet
  • Show the consumer unit and any local appliance isolator
  • Mention access limits, known faults or recent circuit changes
Existing electrical issues should be identified before a new appliance is connected. Repeated tripping may need fault diagnosis, limited consumer-unit capacity may require a fuse box or consumer unit review, and larger projects can be coordinated through our electrical contractor service.
Work Not Included Unless Agreed
  • Internal appliance diagnosis or component repair
  • Cabinet, worktop, decorating or making-good work
  • Gas, water or waste connections
  • Electrical work outside the agreed quotation

07 · Electrical safety, suitability and handover

Why Correct Electrical Appliance Installation Matters

Fixed appliances can place a sustained load on an electrical circuit. Checking the appliance requirements, circuit capacity, isolation and connection method before installation helps avoid unsuitable connections and unnecessary remedial work later.

A fixed or higher-load appliance should not be connected to an unsuitable circuit simply because a connection point is already present. Hot cables, burning smells, repeated tripping, damaged outlets or overheated isolators should be checked promptly by an emergency electrician in London.

Appliance rating and existing supply The Existing Connection Must Suit the New Appliance

A replacement or newly installed appliance may have different electrical requirements from the equipment it replaces. The existing connection should be checked rather than assumed suitable.

Appliance rating

The appliance data provides the starting point for checking the supply, connection method and protective arrangement.

Existing circuit

The existing cable and protective device should be appropriate for the load and installation conditions.

Connection point

The outlet, fused connection unit or fixed connection should match the appliance and remain suitable after installation.

Electrical work in dwellings may need to follow Approved Document P, with the electrical work and certification route determined by the actual installation scope.

Isolation and connection method The Connection Method Must Match the Appliance

Fixed appliances may use different connection methods and isolation arrangements. The correct approach depends on the appliance instructions and the electrical supply already available.

Suitable local isolation

The appliance should have an appropriate means of isolation where required by the installation arrangement.

Accessible connection

The connection point should remain appropriate and accessible for safe isolation, testing or future replacement.

Manufacturer requirements

The connection method, terminals and supply requirements should follow the appliance manufacturer’s instructions.

Older or restricted circuits may need investigation before the appliance is connected, while limited protection may require a consumer unit assessment.

Cable loading and circuit protection The Circuit Must Be Checked Against the Appliance Data

Cable suitability, breaker or RCBO rating, isolation, earthing and fault protection are checked against the manufacturer’s electrical data and the existing installation. A familiar connection point does not prove that the circuit is suitable for a new appliance.

Dedicated supply where required

A dedicated or suitable fixed circuit avoids relying on an unsuitable socket or improvised connection for permanent equipment.

Correct protection and isolation

The protective device and local isolator must suit the equipment, cable and disconnection requirements.

Inspection, testing and certification

Completed electrical work should be tested and the appropriate certificate or building-control route provided.

Electrical work in dwellings must follow Approved Document P. NICEIC is one recognised competent-person route, while other authorised schemes and building-control routes may also apply.

Testing, certification and appliance instructions The Installation Should Be Checked Before Handover

Connecting the appliance is only part of the job. The completed electrical work should be checked as required, with the appropriate certification provided where the installation scope calls for it.

Electrical checks

The electrical connection and any new or altered circuit work should be checked before the appliance is handed over.

Appropriate certification

The certificate or record provided depends on whether the work involved a new circuit, an alteration or a straightforward connection.

Manufacturer instructions

The appliance should be installed and connected in line with the manufacturer’s stated electrical requirements.

Where qualifying electrical work is completed, the relevant electrical installation certification should reflect the work actually carried out.
