House Rewiring in Willesden & Willesden Green
New wiring. A home planned properly around it.
A rewire changes more than the cables behind your sockets. It shapes how you light a room, run a kitchen, control the heating and maintain the home afterwards. Those decisions deserve a clear plan before floors are lifted and walls are opened.

Domestic InstallerScheme
PEP provides full and partial house rewiring in Willesden and Willesden Green, including flats and larger residential refurbishments. We establish what needs replacing, assess what can remain and coordinate the electrical work with the rest of your project.
01 · Define the right installation
Start with the right scope—not an automatic full rewire
An older property does not automatically need every cable replaced. Equally, working lights and sockets do not establish that an installation is suitable for a new kitchen, additional rooms or changed electrical demand.
We assess the existing arrangement alongside your plans, then explain which approach fits:
Partial rewiring:
replacement of defined circuits or areas, with the suitability of retained wiring and its connections checked.
New circuits or local alterations:
targeted work where the supporting installation is suitable and a wider rewire is unnecessary.
Consumer-unit replacement:
renewal of distribution and protection where appropriate. A new board does not repair defective cables elsewhere.
Our consumer unit or full rewire guide explains that distinction. For smaller installations, see our electrical services in Willesden.
02 · Your home. A clearly defined boundary.
Rewiring a flat: establish where your installation begins
In a converted house or managed building, the wiring inside a flat is only part of the picture. The electricity meter may be in a communal cupboard, the supply cable may pass through shared areas, and access may depend on a managing agent or freeholder.
Before agreeing a flat rewire in Willesden, we identify the proposed boundary of the work. That means distinguishing your consumer unit and final circuits from any communal installation, metering equipment or building supply that requires separate attention.
Where a supplier, network operator or building representative must be involved, that dependency belongs in the programme from the outset. Work on shared systems is not silently included in a quotation for one home.
This is particularly useful when buying a converted flat or coordinating work above commercial premises: you need to know which decisions you can make, which require agreement and what could affect the start date.
03 · Work with the building
Different homes need different rewiring plans
A family house being renovated
Opening several rooms together can create an opportunity to reconsider circuits, lighting and services as a whole. We plan access around the structure and finishes, rather than treating every room as an unrelated job.
A converted flat with features to retain
Original floors, cornices and fitted joinery influence the route options. We discuss what can be opened, what needs specialist care and where a proposed layout may have to change to avoid unnecessary damage.
An occupied home with a defined upgrade
Sometimes a limited scope makes more sense than a complete replacement. However, a circuit can serve rooms beyond the one being refurbished. We establish those connections before promising that the work will stay inside one room.
04 · Decisions before first fix
Decide how the home should work before first fix
A useful rewiring plan starts with everyday use. Where will furniture sit? Which appliances are being installed? Where should you switch the landing lights? Which equipment needs an accessible means of isolation?
We work through socket positions, appliance supplies, lighting groups, switching and any agreed data or specialist-system provisions. The kitchen appliance schedule matters: changing a hob, oven or utility layout can change the electrical requirements.
Lighting needs similar attention. A dimmer, driver and fitting must work together, with access to components that may eventually need replacement. Our home lighting design guide helps you consider the layout before choosing fittings.
We also establish a suitable consumer-unit arrangement and consider identified future requirements. Spare capacity or an accessible route can be useful, but it must be designed around a credible plan—not sold as a guarantee that every future addition will be possible.
05 · A connected refurbishment
One coordinated plan for wiring, heating and plumbing
During a refurbishment, electrical work rarely happens alone. A new heating system needs supplies and controls. A kitchen needs water, waste and power in compatible positions. Underfloor heating introduces zones, sensors and equipment that must remain accessible.
PEP can coordinate these connected disciplines within the agreed project scope. With underfloor heating in Willesden, we plan the electrical interfaces and floor-access sequence together. With central heating and plant rooms, we consider supplies, pumps and controls alongside the mechanical installation.
We check the specified products and control arrangements rather than assuming every thermostat or heat source is compatible. Any specialist design, programming or commissioning responsibilities are identified separately.
Where the project also includes plumbing installations, routes and first-fix positions can be agreed together. The practical benefit is fewer conflicting decisions after a wall, floor or cabinet has already been finished.
06 · Respect what is staying
Agree the opening-up work—and who puts things back
Rewiring can involve lifting floors, forming wall chases and opening ceilings. The extent depends on the existing construction, the new layout and which finishes are being retained. We discuss those implications before installation, not after the first cable route is opened.
“Making good” needs a definition. Reinstating a lifted board, filling a chase, preparing a wall for decoration and repainting the room are different tasks. The quotation should identify which are included, who completes the others and when they fit the programme.
Specialist flooring, decorative plasterwork and joinery may require their own contractor. Where work affects fire-resisting or acoustic construction, the appropriate reinstatement also needs to be planned.
For leasehold homes, listed buildings or properties affected by other restrictions, we discuss the relevant approvals and access arrangements. A postcode or conservation-area label alone does not determine the permissions for every proposed alteration.
07 · A clear sequence
From the initial brief to a tested handover
- Understand the property. We review the proposed refurbishment, existing installation, occupancy and available plans. A site assessment helps establish access, retained circuits and any supply or building-management dependencies.
- Define the installation. We agree layouts, equipment, circuit requirements and responsibilities. The written scope distinguishes the work included from exclusions, provisional items and tasks being completed by others.
- Complete first fix. Routes, cables and installation positions are coordinated with the building work. Changes to layouts or appliances are checked before the affected areas are closed.
- Complete second fix. We fit the agreed accessories, equipment and controls when the rooms are ready. Final finishes and access requirements are coordinated with the other contractors.
- Inspect, test and hand over. We carry out the required inspection and testing, check operation, identify circuits and explain the relevant equipment. The documentation records the work actually completed.
Where concealed conditions change the original assumptions, we explain the finding and agree the necessary response. A clearly managed change is better than an undocumented addition to the scope.
08 · Compare the complete brief
What affects house rewiring cost in Willesden?
Bedroom count is only a starting point. Two similarly sized properties can require very different work because of their circuit condition, layout, finishes and access. A flat with shared supply arrangements may involve dependencies that a self-contained house does not.
The main cost factors include:
- The extent of replacement and the assessment of retained circuits.
- The number and specification of points, circuits, fittings and controls.
- Consumer-unit requirements and any necessary supporting work.
- Cable routes, opening-up, occupancy and working restrictions.
- Testing, certification, notification and agreed reinstatement.
Our proposal should make the supply of accessories and fittings clear, alongside exclusions, allowances, VAT treatment and work by others. This gives you something meaningful to compare with another quotation.
Send your plans and equipment choices early where possible. If decisions are outstanding, we identify them rather than presenting an uncertain scope as a settled price.
09 · Plan for people, not just cables
How long will the rewire take—and can you stay at home?
The programme depends on the scope, access, condition of the installation and progress of the wider refurbishment. First fix and second fix may be separated by plastering, joinery or other work, so days spent installing are not necessarily the total elapsed project time.
Some projects can be organised around an occupied home. Others involve enough opening-up and interruption that moving out temporarily is more practical. We discuss working areas, power interruptions and essential household needs before agreeing the approach.
We do not promise uninterrupted power or a universal completion time before assessing the property. The useful commitment is a programme based on the actual work, with dependencies made clear.
10 · A documented finish
Testing, certification and a clear record of the work
The installation is designed and completed to the current applicable requirements of BS 7671 and relevant Building Regulations.
For a full rewire, the handover includes an Electrical Installation Certificate with the relevant inspection and test schedules. Building Regulations notification is a separate process: a full domestic rewire in England is notifiable, with the corresponding compliance documentation required. NICEIC explains the distinction between these documents.
For partial work, certification identifies the scope completed and the relevant limitations; it must not imply that every untouched part of the property has been renewed.
We also explain circuit identification and the operation of the equipment within our scope. The handover should leave you with an installation you understand, not just a folder you cannot interpret.
11 · Experience across London
Experience beyond the individual circuit
PEP is a family-run London contractor, trading since 2010, and an NICEIC-registered Domestic Installer. Our experience combines electrical installation with the plumbing, heating and control interfaces that make a refurbishment work as a complete project.
Five storeys.
Notting Hill residence
At a five-storey Notting Hill residence, PEP designed and delivered electrical infrastructure alongside plumbing and heating. We installed Lutron cabinets to the specialist design and coordinated the interfaces; Lutron design, programming and commissioning remained with the appointed specialist.
14 apartments.
London mixed-use development
Our London mixed-use development project included complete electrical installations for fourteen apartments and customer-side low-voltage infrastructure. Network-owned equipment and other identified specialist systems were delivered by separate contractors.
These are examples of our wider London work, not Willesden case studies. They show why we pay attention to responsibilities and connections between systems, whether the current project is a flat or a larger home.

Before you start
Questions before arranging your rewire
Does an older Willesden home automatically need a full rewire?
No. The decision depends on the installation’s condition, previous alterations and proposed use. Age is relevant background, but it is not a substitute for assessment and appropriate testing.
Can you rewire a flat in a converted house?
Yes. We establish the scope within the flat and identify any shared routes, supply arrangements or access permissions that affect the work. The wider building is not assumed to be included.
What if the meter is outside my property?
Tell us where it is and who controls access. We assess the implications for the project and identify any necessary involvement from the managing agent, supplier or network operator.
Can some existing wiring stay?
Yes, where it is suitable for continued use and the proposed alterations. Retained circuits need assessment; replacing the visible accessories alone does not establish that the wiring behind them is suitable.
Would a new consumer unit be enough?
Sometimes, but it depends on the connected installation. Consumer-unit replacement upgrades distribution and protection; defective or unsuitable wiring needs to be addressed separately.
Can we remain in the property?
Possibly. We consider safe working access, the extent of opening-up and planned power interruptions. For a substantial rewire, temporary alternative accommodation may be more practical than trying to occupy every room throughout.
Are plastering and decorating included?
Only where expressly included in the quotation. We separate electrical installation, opening-up, reinstatement and final decoration so you can see what PEP is providing and what needs arranging with others.
Can rewiring be combined with underfloor heating?
Yes. We can coordinate access, supplies and controls within the agreed scope. Installing UFH does not automatically mean the whole property needs rewiring; the electrical requirements are assessed for the actual system.
Can you quote from plans?
Plans help define the brief and prepare an initial proposal. Existing wiring, routes and access may still need a site assessment before the scope and price can be confirmed.
Which certificates will I receive?
A full rewire receives an Electrical Installation Certificate and the relevant Building Regulations compliance documentation. For a partial project, we explain the certification and notification applicable to the agreed work.
