Circuit installation and alteration enquiries

Situations That May Need a New Circuit or Electrical Alteration

The correct scope depends on what is being added or changed and how the existing installation can support it. A circuit alteration should be planned around the actual requirement rather than treated as a general electrical installation service.

01

New Equipment Needs a Circuit

A new electrical load needs a suitable circuit rather than simply connecting it to an existing point without assessing the installation.

02

An Existing Circuit Needs Extending

The current circuit needs a planned extension to reach an agreed location while keeping the alteration within the supported electrical scope.

03

A Renovation Changes the Electrical Layout

Room or layout changes require electrical connections to be moved, added or altered to suit the new arrangement.

04

The Cable Route Needs to Change

An existing circuit needs rerouting because of an agreed property alteration, access change or revised position of the electrical load.

05

The Job Goes Beyond One Accessory

The requirement is not simply replacing a socket, switch or light fitting and instead involves the circuit supplying the new or altered point.

06

You Are Unsure Whether a New Circuit Is Needed

If it is not yet clear whether the existing circuit can support the proposed change, the installation and intended load need assessment before the scope is confirmed.

Planning the alteration

How New Circuits and Electrical Alterations Are Scoped

The work starts with the intended use and existing installation, then considers the load, route, protective device and testing needed for the agreed circuit work.

Define the Electrical Requirement

Explain what is being added or changed, where it will be located and what equipment or electrical load the circuit needs to serve.

Assess the Existing Installation

The relevant existing circuit, consumer unit position, available access and electrical arrangement are considered before deciding how the work should be carried out.

Plan the Circuit and Cable Route

The proposed circuit or alteration is scoped around the intended load, cable route and protective device requirements for the agreed installation.

Complete, Test and Record

The agreed work is completed and tested, with installation records or documentation provided as appropriate to the electrical work carried out.

Choose the right scope

Circuit Alteration or Electrical Rewiring?

These services solve different requirements. Circuit alterations add or change defined circuits, while rewiring focuses on replacing existing wiring across all or part of the property.

Use Circuit Alterations for Defined Additions or Changes

This service fits when the main requirement is a new circuit, an extension to an existing circuit or a defined alteration associated with a supported electrical addition.

Use Rewiring When Existing Wiring Needs Replacement

Rewiring is the better fit where existing cables need wider replacement across rooms, circuits or the property rather than a single planned addition or alteration.

If the job is already known to be a socket, switch or lighting fitting rather than circuit-level work, use the relevant named electrical service. This page should not become a second broad electrical installation hub.
Before you book

Information That Helps Scope a New Circuit or Alteration

Details about the proposed electrical load, location and existing installation help establish what needs to change and whether the job belongs within this service.

Tell Us What You Want to Add or Change

  • What equipment, connection or property change the new or altered circuit needs to support.
  • Where the new electrical point or load will be located and any known route or access restrictions.
  • Any available information about the existing circuit or consumer unit that may be relevant to the proposed work.

What Can Affect the Scope

  • The electrical load involved and whether a new circuit or alteration to an existing circuit is appropriate.
  • The cable route, access and distance between the supply point and the location of the proposed addition.
  • Whether assessment identifies wider wiring, consumer unit or other electrical work outside the original alteration.
EV chargers and solar PV: these are not confirmed service scopes for this page. A general circuit alteration service should not be presented as EV charger installation, solar PV connection or another specialist system without separate confirmation.
Choose the right electrical service

Does the Enquiry Need a Different Electrical Service?

Use the page that matches the main job once it is clear whether the requirement is circuit-level work, a known accessory, lighting or wider wiring replacement.

If the known job is an accessory

Sockets & Switches

For known socket and switch replacement or supported additions where the main job does not require a separate circuit alteration scope.

 If the main job is lighting

Indoor & Outdoor Lighting

For lighting fittings and suitable lighting work where lighting itself is the main requirement.

 If existing wiring needs replacement

Electrical Rewiring

For full or partial domestic rewiring where the existing wiring needs wider replacement rather than a defined circuit addition or alteration.
A new circuit may be considered when new equipment or a property change needs a separate electrical supply rather than a simple accessory replacement. The intended load and existing installation need to be assessed before the correct circuit scope is confirmed.

Need a New Circuit or Electrical Alteration?

Tell us what you want to add or change, where it will be located and any available information about the electrical load or existing installation so the work can be scoped correctly.
