- Wiring and Circuit Upgrades
- London Appointments
Rewiring Planned Around Your Property and Its Use
Electrical rewiring replaces unsuitable, damaged or outdated fixed wiring and allows the installation to be planned around the way the property is used. The required work can range from one affected circuit to a full rewire, so the property must be inspected before the scope and quotation can be confirmed.
- Initial discussion and property assessment
- Full or partial rewiring considered
- Scope agreed before work begins
Rewiring at a glance
No fixed price is shown because access, circuit requirements, property layout and the condition of the existing wiring all affect the work.
What Electrical Rewiring Involves
Rewiring is planned around the condition of the existing installation, the layout of the property and the electrical demand expected from each area.
01
Replacing Existing Wiring
Wiring and circuits that are unsuitable or in poor condition can be replaced as part of a defined rewiring plan.
02
Planning the Required Points
Socket outlets, switches, lighting points and fixed supplies are considered against the way each room will be used.
03
Testing the Completed Work
New circuits are inspected and tested after installation, with the relevant documentation prepared for the completed electrical work.
When a Rewiring Assessment Makes Sense
The age of a property alone does not confirm that it needs rewiring. The decision should be based on the condition, safety and suitability of the fixed installation.
01
Damaged or Deteriorated Wiring
Visible damage, heat marks or deterioration may indicate that part of the installation needs closer inspection.
02
Repeated Electrical Problems
Frequent tripping, intermittent faults or circuits that no longer perform as expected need proper investigation.
03
Unsuitable Earlier Alterations
Previous additions may not suit the present layout, loading or protection of the installation.
04
Renovation or Layout Changes
Major refurbishment can provide an opportunity to reposition points and replace wiring before finishes are completed.
05
Insufficient Circuits or Outlets
A property may need a better circuit arrangement where existing points no longer support normal use.
06
Findings from an Electrical Report
An inspection may identify wider deterioration or several affected circuits that need a separate rewiring review.
Confirm the Condition Before Choosing the Work
Where the condition of the installation is unclear, an Electrical Installation Condition Report can record defects and test results. A localised issue may lead to repair work, while wider findings can support a partial or full rewiring assessment.
What We Review Before Confirming the Scope
Rewiring quotations depend on the actual property. A review helps establish what can remain, what needs replacing and how the work can be carried out with realistic access.
Existing circuits
Condition and Arrangement
We consider the existing circuit layout, visible wiring condition and any known test results or previous reports.
Property use
Current Electrical Demand
The number and location of outlets, lighting points and fixed supplies should match how the rooms are actually used.
Access
Floors, Walls and Ceilings
Access routes affect how cables can be installed and which areas may need opening before the work can proceed.
Future plans
Upcoming Electrical Loads
Planned equipment and property changes should be discussed before the final circuit arrangement is agreed.
Why an assessment is required
Two similar-sized properties can need very different work. The number of circuits, access, occupancy, finish level and intended use all affect the rewiring plan.
The assessment can also identify related work that should be planned at the same stage, such as a consumer unit replacement, an EV charger supply or dedicated wiring for a fixed air-conditioning system.
How the Work Is Planned and Carried Out
The sequence depends on the property, access and agreed scope. The main stages below show how a rewiring project is usually organised.
01
Discuss the Property
We review the reason for the enquiry, known problems, planned use and any renovation work.
02
Inspect and Plan
We assess the installation, discuss access and define the circuits and electrical points required.
03
Agree the Scope
The proposed work, exclusions and practical arrangements are confirmed before the project starts.
04
Install and Test
The agreed wiring is installed, inspected and tested, with final checks completed before handover.
Prepare Access and Coordinate Other Trades
Clear planning reduces avoidable disruption and helps the electrical work fit around building, decorating or renovation schedules.
- Confirm which rooms and circuits are included
- Discuss occupied and vacant areas
- Identify furniture, flooring and access restrictions
- Coordinate plastering, joinery and decoration
- Making good, plastering and decoration
- Specialist data, alarm or control systems
- Removal or relocation of furniture and fitted units
- Work outside the agreed rewiring scope
What Can Change the Rewiring Scope
The final plan is shaped by more than the number of rooms. Access, retained wiring, new electrical loads and the required finish all need to be considered.
01
Existing Installation
The condition and arrangement of existing circuits determine what may remain and what needs replacement.
02
Access and Construction
Solid floors, finished walls, fitted furniture and restricted routes can change how the wiring is installed.
03
New and Future Loads
Additional equipment may require dedicated circuits or changes to the planned distribution of power.
04
Finishes and Making Good
The agreed responsibilities for access openings, repairs and decoration should be clear before work begins.
Partial rewire
Used where the required work is limited to defined circuits or areas.
Full rewire
Considered where the replacement needs to cover the wider fixed installation.
Related upgrades
Additional supplies and protective equipment are reviewed as part of the project plan.
Plan Wider Electrical Work Before Walls Are Closed
Where the property is being refurbished, wider electrical installations can be coordinated with the rewiring plan before finishes are completed.
Why Rewiring Needs a Property Review First
We do not publish a fixed rewiring price because the required work cannot be confirmed from the property type or bedroom count alone.
Tell Us What Is Changing
Share the property type, affected areas, known electrical issues and any renovation plans.
Review the Existing Installation
Access, circuit arrangement, consumer unit condition and the proposed electrical points are considered on site.
Confirm What Is Included
The quotation should state the agreed electrical work and identify any exclusions or separately arranged items.
Plan Access and Occupancy
The sequence depends on room access, other trades and whether the property remains occupied during the work.
A quotation can only be prepared after enough information has been gathered to understand the work. Additional defects or inaccessible wiring discovered later may need separate review before any change to the agreed scope.
Why Electrical Rewiring May Be Needed
Electrical rewiring replaces unsuitable or deteriorated wiring and allows circuits, sockets, lighting points and fixed equipment supplies to be planned around the way the property is used. The correct scope can only be confirmed after the existing installation, access and planned changes have been reviewed.
Condition and safety
Older Wiring Does Not Always Mean a Full Rewire
Older Wiring Does Not Always Mean a Full Rewire
The age of a property alone does not determine the work. The wiring, accessories, joints, earthing arrangements and protective devices need to be assessed before deciding whether individual repairs, circuit replacement or wider rewiring is appropriate.
Deteriorated cables or accessories
Heat, moisture, physical damage and previous alterations can affect cables, sockets, switches and connections.
Unsafe or unsuitable alterations
Earlier DIY work or poorly planned additions may leave circuits with unsuitable connections, loading or protection.
Local fault or wider problem
A problem affecting one circuit may need targeted investigation rather than rewiring the whole property.
Where the concern appears limited to a circuit, accessory or intermittent fault,
electrical fault finding and repair
can help establish the cause before broader work is considered.
Capacity and future use
The New Installation Should Match How the Property Will Be Used
The New Installation Should Match How the Property Will Be Used
Rewiring gives the electrical layout an opportunity to reflect current and planned use. Socket positions, lighting controls, kitchen equipment, heating, home offices and fixed electrical systems should be discussed before cable routes and circuit arrangements are agreed.
Rooms and fixed equipment
The number and position of electrical points should suit the room layout and the equipment that will be connected.
Separate circuit requirements
Higher-load equipment and specialist systems may need dedicated circuits rather than being added to an existing arrangement.
Planned changes
Extensions, loft conversions, kitchen work and future equipment can affect the design and timing of the rewire.
Tell us about planned systems at the assessment stage. Supplies for
EV charger installation,
fixed
air-conditioning equipment
and
data wiring and cabling
may need to be coordinated with the electrical work.
Access and sequencing
Rewiring Needs to Be Planned Around the Building Work
Rewiring Needs to Be Planned Around the Building Work
Cable routes may pass through walls, floors, ceilings and service areas. Access, finishes, furniture, occupancy and other trades all affect how the work can be carried out and what preparation may be needed before the installation starts.
Occupied or empty property
An occupied home requires different access and sequencing from an empty property undergoing renovation.
Decorative finishes
Existing wall, ceiling and floor finishes can affect cable routes and the level of opening or making good required.
Coordination with other trades
Electrical first-fix and second-fix work should be arranged around plastering, joinery, kitchens and other building work.

Assessment before quotation
The Scope and Cost Depend on a Property Review
The Scope and Cost Depend on a Property Review
Rewiring cannot be priced accurately from the number of bedrooms alone. The quotation depends on the condition and layout of the installation, circuit requirements, access, finishes, occupancy and the electrical points or fixed systems included in the work.
Review the existing installation
We need to understand the consumer unit, circuit arrangement, accessible wiring and any known electrical concerns.
Discuss the required layout
Socket outlets, lighting points, controls, equipment supplies and future plans should be agreed before the scope is prepared.
Confirm access and exclusions
The quotation should state the agreed electrical work, access assumptions and any making good or related work not included.
An existing
Electrical Installation Condition Report
can provide useful background, but a separate rewiring consultation and property review
are still needed to confirm the work to be quoted.
Arrange an Electrical Rewiring Assessment
Send us the property details, planned changes and any existing reports. We will review the requirements and arrange a consultation or site visit before confirming the scope and preparing a quotation.
Details We Need Before Planning Your Electrical Rewire
Electrical rewiring needs to be assessed around the existing installation, the planned layout and how the property will be used. A site visit and review are needed before we confirm the work or provide a quotation.
Property and Existing Wiring
Tell us whether the property is a flat, house, HMO or commercial premises, along with any known issues or previous electrical work. Where the condition is unclear, an EICR inspection may help establish what needs attention.
Planned Electrical Layout
Explain any proposed changes to sockets, lighting, appliances or room layouts. This allows the new circuits and electrical points to be planned around the finished property, including any future EV charger requirements.
Access, Occupancy and Finishes
Let us know whether the property is occupied, empty or being renovated, and where walls, floors or ceilings can be opened. If the concern is limited to one area, electrical fault finding may be more suitable than a wider rewire.

Assessment before scope and quotation
Rewiring should be planned around the existing installation, the property layout and the electrical points required. A site review is needed before the work, programme and quotation can be confirmed.
01 What does electrical rewiring involve?
Electrical rewiring replaces unsuitable or deteriorated cables and updates the circuits serving the property. The exact work depends on the existing installation, the planned room layout and which electrical points need to remain, move or be added.
02 How can I tell if my property may need rewiring?
Repeated faults, damaged accessories, signs of overheating, unreliable circuits or concerns raised in an electrical report may justify further assessment. If there is an active fault, arrange electrical fault finding rather than assuming that a complete rewire is required.
03 Why is a site survey needed before rewiring is quoted?
A site survey allows us to review the existing wiring, consumer unit, circuit layout, access routes and proposed electrical points. We also need to understand whether the property is occupied or being renovated. This information is needed before the work and quotation can be prepared properly.
04 How long does an electrical rewire take?
The programme depends on the size and layout of the property, the agreed scope, access and whether other building work is taking place. A partial rewire may require less time than work across the whole property. The expected schedule should be confirmed after the survey.
05 Will walls, ceilings or floors need to be opened?
Cable routes may require access behind finishes, below floors or through ceilings. The amount of opening depends on the construction of the property and the routes available. Access requirements, making good and decorative work should be clarified before the job starts.
06 Can sockets, lighting and appliance supplies be changed during a rewire?
Yes, the proposed layout should be discussed before work begins. This is the stage to confirm socket positions, lighting controls and supplies for fixed appliances. Planned EV charging or data cabling requirements should also be raised early so the electrical routes can be considered together.
07 Is rewiring the right response to sudden tripping or a burning smell?
Not necessarily. Sudden power loss, repeated tripping, sparking, heat or a burning smell should be investigated promptly. An emergency electrician or targeted fault finding may identify a local problem without committing the property to wider rewiring.
08 Does an older property always need a full rewire?
No. The age of a property alone does not confirm that every circuit must be replaced. Some installations need a full rewire, while others may only need work to particular circuits or areas. The wiring should be assessed before the scope is agreed.
09 What is the difference between a full and partial rewire?
A full rewire covers the electrical installation across the property. A partial rewire is limited to agreed circuits, rooms or sections. The right approach depends on the condition of the existing wiring and whether unaffected parts can remain safely in service.
10 How much does electrical rewiring cost?
Electrical rewiring does not have one fixed price. The cost depends on the property, number of circuits, required sockets and lighting points, access, finishes and the extent of the work. A quotation can be prepared after the installation and proposed layout have been reviewed.
11 Can rewiring be completed while the property is occupied?
This depends on the scale and layout of the work. Rewiring normally involves circuit isolation, access to several rooms and disruption to normal use. An empty property is often easier to plan, but occupied work can be discussed during the assessment.
12 Does a rewire always require a new consumer unit?
Not automatically. The existing consumer unit and protective devices need to be reviewed as part of the installation. If they are unsuitable for the proposed circuits or require replacement, a fuse box or consumer unit upgrade can be included in the planned work.
13 Do I need an EICR before arranging a rewire?
Not in every case. Where the condition of the existing installation is uncertain, an EICR can provide useful information about the fixed wiring and affected circuits. A rewiring survey is still needed to plan the new layout and confirm the actual scope.
14 What information should I provide before requesting an assessment?
Provide the postcode, property type, approximate layout, occupancy status and details of any renovation work. Mention known electrical problems, previous reports and proposed changes to sockets, lighting, appliances or rooms. This helps us prepare for the site visit.
Arrange a Review Before Planning the Rewire
Send us the property details and proposed electrical changes. We will review the requirements before confirming the scope and quotation.
