Make the electrical plan follow the way the home will be used.
A good electrical installation begins with the finished property, not with a list of socket quantities.
Furniture, joinery, kitchen equipment, lighting, heating controls and future maintenance all influence where power is required and how circuits should be arranged. Where the electrical scope includes floor-heating supplies, thermostats or sensors, see our underfloor heating service in Chiswick.
PEP reviews that information before routes are fixed. If the project includes a new kitchen, rear extension, loft room or reorganised ground floor, we consider the retained house and the new space together.
Residential electrical work
Electrical services for Chiswick homes and refurbishment projects.
The final specification is tailored to the property and the work being undertaken, then delivered as one coordinated package.
New circuits and dedicated supplies
Power and lighting circuits for fixed appliances, heating equipment, pumps, ventilation, garden rooms and other agreed loads.
Lighting and control infrastructure
Wiring, controls and connection points for architectural lighting, with switching, dimming, drivers and access resolved before first fix.
Distribution and protection
Consumer-unit, circuit, earthing and bonding requirements assessed together with the proposed electrical load.
Inspection, testing and handover
Completed work is inspected and tested, circuits are identified and the appropriate electrical documentation is provided.
01 · Survey & planning
Chiswick property context
Connect established rooms and new spaces as one installation.
Residential projects in Chiswick can involve very different starting points.
A Bedford Park or Turnham Green house may retain decorative plasterwork, timber floors and fitted joinery. A property towards Grove Park or Old Chiswick may include later extensions, garden buildings or several generations of electrical alterations.
Flats near Chiswick High Road may sit within converted or managed buildings where access and responsibilities need to be agreed in advance.
Where an older part of the house meets a new rear extension, the new kitchen and lighting may require additional circuits while retained rooms continue to use existing wiring. The interface must be assessed rather than assumed.
We do not assume that a property needs replacing throughout because of its age or postcode. The scope follows evidence from the survey, available records and appropriate testing.
Consumer unit and distribution
Assess the consumer unit with the circuits it protects.
The consumer unit is the distribution point for the installation, but its appearance alone does not explain the condition of every connected circuit.
Before adding loads or recommending replacement, the existing circuit arrangement, protective devices, earthing, bonding and available capacity need to be understood.
Replacing a fuse box does not repair faults elsewhere in the property. Equally, an older unit does not automatically mean that the entire house needs rewiring.
If replacement is the defined scope, our dedicated page explains the assessment, changeover, testing and documentation in more detail.

02 · Distribution & protection
Choosing the scale of work
Define the scope from the installation and the planned changes.
Not every project needs a full rewire, and not every alteration can be treated as a small addition.
A defined package
An extension, kitchen, loft, plant area or selected rooms may form a clear package where retained circuits are suitable for the proposed connection.
Partial or full replacement
Wider replacement may be justified where circuits are unsuitable, extensively altered, poorly documented or incompatible with a major refurbishment.
03 · Coordinated installation
Coordination before first fix
Agree every electrical interface while the routes are still open.
Electrical work crosses almost every part of a residential refurbishment.
A kitchen designer may specify appliance loads. A lighting designer may set fitting positions and controls. Heating equipment needs defined supplies. Joinery can conceal sockets, drivers or access panels.
PEP can coordinate the electrical requirements with homeowners, architects, interior designers, main contractors and specialist installers. Each party’s responsibility is recorded so that providing a cable is not confused with designing or commissioning the connected equipment.
- Architectural and interior layouts
- Kitchen, utility and fixed-appliance schedules
- Lighting plans, fittings and switching information
- Heating, ventilation and plant requirements
- Joinery drawings and furniture positions
- Accessory finishes and procurement responsibility
- The proposed construction and decoration sequence
Occupied homes
Plan access, isolation and protection before work begins.
Electrical work in an occupied home needs a different programme from work in an empty property.
The survey establishes which rooms are available, when circuits can be isolated and whether temporary arrangements are practical. PEP explains the intended sequence and the areas requiring access before the quotation is finalised.
Electrical installation can require access behind walls, floors or ceilings. Responsibility for protection, opening up and making good must be clear rather than assumed.
Flats and managed buildings
Confirm building responsibilities outside the front door.
A converted flat can depend on access and approvals beyond the private rooms.
- Freeholder or managing-agent requirements
- Agreed working hours and common-area access
- Isolation arrangements and meter locations
- Fire-stopping and service-penetration responsibilities
- The boundary between private and communal systems
PEP defines the electrical scope it controls and identifies information required from others before installation proceeds.
From enquiry to handover
How PEP delivers a residential electrical project.
Clear decisions before installation, coordinated work on site and appropriate documentation at completion.
Understand
Send the W4 postcode, property type, proposed work and any available drawings, photographs or electrical report.
Survey
We review the accessible installation, proposed rooms, likely loads and practical routes.
Define
The quotation records inclusions, responsibilities, assumptions, exclusions and known interfaces.
Coordinate
Circuits, accessories, lighting and specialist supplies are checked against the latest project information.
Install
First-fix and second-fix work follows the agreed sequence, with site changes discussed openly.
Hand over
The finished scope is inspected and tested, circuits identified and applicable documentation provided.
The finished result
Power and lighting resolved around the rooms, not added afterwards.
The most useful installation decisions are made while layouts, routes and access can still change.
Socket positions, lighting layers, controls, joinery and fixed equipment work best when they are coordinated as parts of the same home.
Individual survey · individual quotation
What shapes the cost of electrical work in Chiswick?
A useful quotation cannot be produced from the postcode or floor area alone.
Two similar houses may require different work because the existing wiring, access, finishes, equipment and project stage are different. PEP develops the price from a defined scope.
- Property size, layout and type
- Number and purpose of new or altered circuits
- Condition and clarity of the existing installation
- Access behind walls, floors and ceilings
- Whether the home remains occupied
- Kitchen, lighting, heating and specialist requirements
- Equipment selections and project phasing
- Testing, certification and notification requirements
- Responsibility for protection, opening up and making good
For the most useful first review, send your W4 postcode, property type, project stage, drawings, photographs and any previous installation information.
Why early detail matters
Resolve the electrical decisions before finished work conceals them.
A clear scope gives the homeowner and every contractor a common reference.
When information changes, the electrical effect can be reviewed before an accessory conflicts with joinery, a driver becomes inaccessible or a new load is assigned to an unsuitable circuit.

Common project questions
Electrical work in Chiswick.
If drawings, equipment schedules or earlier certificates are available, send them with your enquiry. If the scope is still developing, we can help establish the practical next step.
07825 268 43401What residential electrical work does PEP undertake in Chiswick W4?
PEP delivers planned installations, alterations and upgrades for homes and refurbishments. The scope can include power, lighting, kitchen supplies, distribution, heating or ventilation supplies, first fix, second fix, testing and completion documents.
02Can PEP provide electrical work for a rear extension or refurbishment?
Yes. We assess how the new rooms connect to the retained house and whether the existing installation can support the proposed loads. Early involvement allows circuits and routes to be coordinated before finishes close access.
03How do you decide whether a property needs a full rewire or a partial upgrade?
The decision follows the installation’s condition, proposed changes, access and suitability of retained circuits. Property age alone is not enough. PEP explains the evidence before agreeing the scope.
04Can the consumer unit be replaced without rewiring the whole house?
It can, where assessment and testing show that the circuits are suitable and any remedial work is understood. A new consumer unit does not correct unrelated wiring defects.
05Can electrical work be completed while we remain in the house?
Some defined packages can be organised in an occupied property. The answer depends on access, affected circuits and opening-up requirements. We agree the sequence, protection and access before confirming the programme.
06Do you work in period homes, converted flats and managed buildings?
Yes, subject to survey. Period interiors may require careful routes around retained plasterwork, floors and joinery. Flats can involve managing-agent conditions, common areas and shared services.
07Can PEP coordinate electrical work with heating, plumbing and specialist systems?
Yes. PEP provides electrical, heating and plumbing services for residential projects. We can coordinate agreed supplies and containment while recording who designs, supplies, connects and commissions each item.
08What certificates and records will I receive?
Documentation depends on the completed work. New installations, additions or alterations are inspected and tested, with the appropriate certificate issued for the agreed scope. Where work is notifiable, the Building Regulations process also applies.
09How is electrical work in Chiswick priced?
PEP prices a defined scope rather than a postcode estimate. We consider the existing installation, circuits, access, equipment, finishes, programme, testing and making-good responsibilities.
