Serving Central, West and North West London.
Domestic Installer SchemeCertified since 2010Property-wide planning
A successful house rewire is more than replacing old cable. It is an opportunity to design an electrical installation around the way the completed property will be occupied, furnished and used.
Sockets need to work with furniture and joinery. Kitchen circuits need to match the final appliance schedule. Lighting supplies and controls need to follow the lighting design. Heating equipment, pumps, ventilation, security, data and audiovisual systems may all need power, containment or defined interfaces.
PEP brings these requirements together before installation begins. We can work directly with the homeowner or coordinate with architects, interior designers, main contractors and specialist system installers. Early decisions reduce late changes, avoid conflicts between services and produce an installation that is easier to test, document and maintain.
When to consider a rewire
Age alone does not prove that a property needs a full rewire. The decision should follow an assessment of the existing installation, its condition and whether it is suitable for the proposed use of the home.
Reasons to arrange an electrical assessment can include:
Visible warning signs should be investigated by a competent electrician. In other cases, an Electrical Installation Condition Report or a project survey may be the right starting point. The result may support a complete rewire, a partial rewire or targeted remedial work. PEP will not recommend replacing the whole installation where the evidence and agreed project scope do not justify it.
Define the right scope
The right approach depends on condition, access, proposed loads, the building programme and how retained circuits will interface with the new work. PEP defines that boundary during the survey and planning stage so the quotation is based on an agreed scope rather than assumptions.
A full house rewire replaces the fixed wiring and associated electrical infrastructure throughout the agreed property. It is commonly considered when the existing installation is unsuitable, when several generations of work have created an unclear system, or when a complete refurbishment makes a planned replacement practical.
A partial rewire is limited to specific areas, circuits or phases of a project. It may be appropriate for a kitchen, extension, loft conversion, plant area or part of a property where the remaining installation has been assessed and can be retained safely.
Plan before first fix
Early information reduces late changes and prevents conflicts between services.
PEP reviews the room layouts, loads, kitchen and bathroom information, lighting design and specialist-system requirements before circuits and routes are agreed.
What the work can include
The final specification is tailored to the property. Depending on the survey, drawings and agreed requirements, the work can bring power, lighting, distribution, specialist supplies and handover information into one organised package.
New power, lighting, kitchen, utility and dedicated equipment circuits.
Connection points planned around furniture, joinery and how each room will be used.
Consumer-unit and distribution requirements assessed as part of the overall design.
Electrical infrastructure for heating, ventilation, lighting, security, data and AV.
Requirements identified through design, inspection and the condition of the installation.
Inspection, testing, labelling, certification and information for the completed scope.
Accessories, decorative finishes, lighting equipment and specialist systems should be selected early enough to confirm compatibility, lead times and responsibility for supply, installation and commissioning.
From survey to handover
Clear decisions early, coordinated installation on site and a documented close-out.
We review the existing installation, the condition and construction of the property, access constraints and the proposed scope.
Circuits, points, equipment supplies, consumer-unit requirements and service interfaces are identified and coordinated with the wider programme.
Before concealed work begins, we agree practical cable routes, back-box positions, access requirements and the treatment of existing finishes.
Cabling, containment, back boxes and concealed infrastructure are installed while walls, floors and ceilings are accessible, sequenced with other trades.
Sockets, switches, controls, consumer units and agreed equipment connections are installed when the property and finishes are ready.
The completed installation is inspected and tested; results are recorded and the applicable certification and Building Regulations documentation are prepared.
Working in an occupied home
Some rewiring work can be organised in an occupied property, but this must be assessed rather than promised in advance.
A rewire involves isolations, restricted access, noise, dust and work behind finished surfaces. There may also be periods when particular rooms or services cannot be used. During the survey, PEP considers the extent of the work, safe access, temporary arrangements, furniture and possessions, working hours and the sequence in which rooms can be released. For a larger rewire, an empty property or temporary absence during disruptive phases may create a safer and more efficient programme.
We explain the practical constraints before the work begins so that the programme reflects the property and the people living in it.
Period homes & refurbishments
London homes can present very different construction, access and conservation challenges. Period houses, converted buildings, apartments and properties with extensive joinery or specialist finishes require careful route planning before first fix.
In a complete refurbishment, the best results usually come from coordinating the electrical design with architectural information and the programme for structure, plastering, flooring, kitchens, bathrooms and decoration. Decisions about socket positions, lighting, controls and equipment supplies should be made before surfaces are closed.
PEP’s role is to keep the electrical scope clear while coordinating the interfaces that cross into heating, plumbing, mechanical equipment, lighting controls, security and audiovisual systems. This is particularly valuable in technically demanding homes where several specialists must work from the same information.
Project cost
There is no responsible fixed price for every two-, three- or four-bedroom property. Two homes with the same number of rooms can require very different circuits, access arrangements, finishes and coordination.
PEP first establishes the project information and, where required, surveys the property, then prepares a defined scope and quotation based on the actual installation rather than a generic room count.
Project programme
The programme depends on the size and construction of the property, the amount of electrical work, access, occupancy, selected finishes and the wider refurbishment sequence. A rewire completed in an empty property with open floors and coordinated drawings is a different project from phased work in an occupied, finished home.
PEP confirms the expected sequence after the survey and review of the available information. Where other trades control access or completion dates, those dependencies are identified before work starts.
Certification & Building Regulations
PEP is registered under the NICEIC Domestic Installer Scheme for domestic electrical installation work.
Electrical work is designed, installed, inspected and tested against the standards applicable to the agreed scope at the time of the work. A full house rewire is expected to require an Electrical Installation Certificate. Where the work is notifiable under Building Regulations, the appropriate Building Regulations compliance process and certificate also apply.
Because requirements depend on the exact project and current regulations, PEP confirms the certification and notification route for the property before work begins. At handover, the client should understand what has been installed, how circuits are identified and which documents relate to the completed electrical scope.
Inspection and certification
Clear results, recorded and explained at handover.
The completed installation is inspected and tested against the requirements applicable to the agreed scope at the time of the work.
One accountable team
Electrical work rarely exists in isolation during a major residential refurbishment. Boilers, pumps, valves, underfloor-heating controls, ventilation equipment, plant-room components, kitchen appliances and specialist systems all depend on correctly planned power or control interfaces.
Power and control interfaces for boilers, pumps, valves, underfloor heating and plant equipment.
Infrastructure aligned with architectural lighting, dimming and specialist commissioning requirements.
Agreed containment and power arranged before finishes close access to the installation.
PEP provides electrical, heating and plumbing services for London residential projects. Where the scopes overlap, our team can coordinate requirements early, define responsibility and reduce the risk of one trade waiting for information from another. Specialist lighting, security, automation and audiovisual systems may still be designed or commissioned by their respective specialists; PEP can provide and coordinate the agreed electrical infrastructure they require.

Common questions
If the project is already designed, send the drawings. If it is still taking shape, bring us in early and we will help define the practical route forward.
07825 268 434The decision should be based on the condition and suitability of the existing installation. An assessment, and in some cases an Electrical Installation Condition Report, can identify defects, deterioration and limitations. The outcome may be a full rewire, a partial rewire or targeted remedial work.
A full rewire replaces the fixed wiring and associated infrastructure throughout the agreed property. A partial rewire is limited to defined areas or circuits. Retained parts of the installation must be assessed so the boundary between old and new work is safe, clear and testable.
Sometimes, but it depends on the scale of the work, required isolations, safe access and the condition of the property. PEP discusses occupancy and disruption during the survey and will explain where temporary absence may be the more practical option.
Rewiring normally requires access to concealed cable routes, back boxes and connection points. The extent depends on the construction and the routes available. PEP reviews access and the boundary for lifting, chasing and making good before the quotation is agreed.
Yes. A rewire is the right time to plan points around furniture, joinery, kitchens, lighting and future use. Decisions should be made before first fix because late changes can affect routes, cost and programme.
The consumer unit and distribution arrangement are assessed as part of the project. A new or revised unit may form part of a full rewire, but the final specification depends on the design, existing supply and agreed electrical scope.
Property size is only one factor. Circuit quantity, access, occupancy, finish protection, specialist equipment, lighting controls, consumer-unit requirements and coordination with other trades can materially change the scope. PEP prepares a quotation after the requirements have been defined.
Duration depends on the property, access, occupancy, specification and wider building programme. PEP confirms the likely sequence and project-specific timetable after survey and review of the available drawings or schedules.
A full rewire is expected to require an Electrical Installation Certificate. Where the work is notifiable, a Building Regulations Certificate of Compliance also applies. PEP confirms the document route for the agreed project before work starts.
Yes. PEP can work directly with homeowners or coordinate the electrical installation with architects, interior designers, main contractors and specialist system installers. Early coordination is particularly useful before first fix.
PEP primarily serves Central, West and North West London. For a larger project elsewhere in London, send the postcode and scope so we can confirm whether it fits our delivery area.
Start with the property and scope
If you are planning a full refurbishment, replacing an unsuitable installation or deciding between a full and partial rewire, send PEP the property postcode and any available drawings, schedules or survey information. We will review the intended scope, explain the practical next step and confirm whether a site survey is required before a quotation can be prepared.
