Fuse box upgrades · Ealing W5 & W13
Modern protection. A clear scope. A carefully managed changeover.
PEP replaces consumer units and older fuse boxes in Ealing homes and flats. We assess the existing installation, specify suitable protection and plan the work around the property you live in — from the first checks to testing, certification and handover.
NICEIC-registered Domestic Installer · Planned residential electrical work
Domestic Installer01 · The reason comes first
Your consumer unit is where the circuits serving your home are distributed and protected. Replacing it should begin with a reason: unsuitable protection, damaged equipment, an installation that has been altered over time or electrical work that the existing arrangement cannot properly accommodate.
You might be preparing a kitchen renovation in Northfields, reviewing a flat in West Ealing or planning the next stage of a family home refurbishment. The question is not simply which new board will fit. It is whether the existing circuits are suitable to reconnect and what the completed installation needs to support.
Repeated tripping needs investigation, not an automatic sales pitch for a replacement. A faulty appliance or wiring problem can remain after a new board is fitted. Our guide to an RCD that keeps tripping explains that distinction.
Equally, age or a plastic enclosure alone does not establish that an installation is unsafe. The recommendation should follow its condition and suitability, not appearance alone.
02 · Know what is included
A useful quotation tells you what happens to the installation, not just the price of the enclosure. Two jobs with the same number of circuits can need different preparation, access arrangements and remedial work.
We establish the scope before confirming the price. Your quotation should make clear:
Moving the board, extending cables, improving earthing or bonding, adding circuits and arranging access to supply equipment can change the cost. These should not disappear inside a vague promise to “upgrade the fuse box”.
Where further work is identified, we explain the finding and the proposed scope before proceeding with additional work, while keeping the installation safe. You can then compare quotations on a like-for-like basis rather than choosing between incomplete headline prices.
03 · Different work. Different scope.
A board replacement changes the distribution and protection equipment. It does not renew all the wiring concealed behind your walls, beneath floors or above ceilings.
Where existing circuits are suitable, they may be retained. Where a particular circuit needs repair or renewal, that can be defined separately. If the property needs extensive new wiring, a different layout or major electrical changes, it may be more sensible to plan a wider installation.
We separate those decisions clearly. Explore our full and partial rewiring service in Ealing, or read the detailed comparison of consumer unit replacement and a full rewire.
04 · Protection with a purpose
The specification should suit the installation and current requirements, rather than start with a standard package selected before the circuits have been assessed.
An RCBO combines residual-current and overcurrent protection for an individual circuit. An appropriately designed arrangement can reduce the disruption caused when a fault on one circuit trips protection shared with others. It does not remove the need to find and correct the fault itself.
Surge protective devices help limit transient overvoltages affecting the installation and connected equipment. Their provision is considered against the applicable requirements, not treated automatically as an optional luxury.
AFDD requirements depend on the installation and circumstances. We establish the appropriate provision rather than claiming every home needs the same configuration. Devices, enclosure and assembly must also be compatible; a spare physical slot is not the only consideration.
For a homeowner-friendly explanation of the different devices, see NICEIC’s consumer unit guidance.
05 · Designed around the property
A kitchen extension, loft conversion and heating upgrade may have been completed years apart. We look at how the existing circuits are arranged, what the labels actually identify and what your next project will need. This helps turn separate additions into an agreed electrical plan.
In a converted property or apartment building, your consumer unit may be separate from the meter and equipment in a communal cupboard. Before booking the changeover, we establish access, isolation arrangements and whether another party needs to be involved. Work to shared or supply equipment is not silently included in a domestic board replacement.
A board inside joinery, beneath a staircase or beside recently decorated walls needs practical consideration. We discuss working space, accessibility, cable routes and any agreed making-good. Moving the unit is a separate decision, not something to improvise once the power is off.
06 · Assess. Install. Verify.
We begin with your reason for replacing the board, the property layout and any planned additions. Photographs can help that conversation, but they cannot establish the condition of hidden wiring or replace inspection and testing.
Electrical Safety First recommends an Electrical Installation Condition Report before a planned replacement. If a full EICR is declined, a pre-work survey is still necessary; the replacement should not proceed without the appropriate assessment. See its consumer unit replacement guidance.
Once the findings and scope are understood, we agree the specification, preparation and changeover arrangements. Installation is followed by the required inspection, testing, circuit identification and handover.
If a circuit cannot safely be reconnected, we explain the defect and next steps. It must be made safe, which may mean leaving it disconnected pending remedial work.
07 · Plan the interruption
A consumer unit replacement interrupts the electrical supply while the work is carried out. We discuss the expected working period after assessing the installation, including testing and any agreed associated work.
Tell us about working from home, refrigeration, heating controls, alarms and equipment that must remain available. If anyone depends on electrically powered medical equipment, suitable arrangements must be in place before the planned interruption. A date in the diary is not a continuity plan.
We also agree access to the board, relevant rooms and any communal cupboards. Keeping the working area available matters as much as choosing a convenient start time.
You receive a realistic plan for your property. We do not promise every installation will take the same number of hours or that an unsafe circuit will be reconnected simply to meet a schedule.
08 · A documented handover
The replacement work is inspected and tested, with an Electrical Installation Certificate and the relevant schedules provided. Circuit descriptions should make the finished board understandable, not leave you guessing which switch serves which part of the home.
An EIC records the installation work covered by the certificate. It should not be confused with a full condition report on the entire property.
Consumer unit replacement is notifiable work in England. We handle the applicable notification through our registration arrangements, alongside the electrical certification. These are related but distinct parts of the handover. Approved Document P explains the Building Regulations framework.
Our work is specified against the current BS 7671 requirements and applicable amendments. That does not turn every difference in an older installation into an automatic requirement for a complete rewire.
09 · Think beyond the enclosure
If you are planning a new kitchen, extension or heating installation, tell us before the consumer unit is specified. Agreeing likely circuits and equipment early can avoid an upgrade that overlooks work already on the horizon.
Capacity means more than spare ways in the enclosure. The existing supply, circuit requirements and protective arrangements also need consideration. A larger consumer unit does not increase the capacity of the incoming electricity supply by itself.
We can coordinate the agreed electrical scope with kitchen electrical planning, central heating installations in Ealing and heating controls, where those form part of your project.
10 · A clear scope, from start to finish
PEP is a NICEIC-registered Domestic Installer with an approach built around planned residential work. Our wider electrical, plumbing and heating services let us consider the board alongside the equipment and alterations it will serve.
We explain what needs replacing, what can remain and what must be addressed separately. The aim is a properly scoped installation, with decisions made before the changeover and a clear record of the completed work.

Before you book
Yes, where the existing circuits are suitable to retain. Assessment may identify repairs or individual circuits needing renewal, but a consumer unit replacement does not automatically mean a full rewire.
The specification, circuit count, condition, location and associated work determine the quotation. We establish what is included and identify additional requirements rather than offer one price for every Ealing property.
We estimate the interruption after assessing the work. Access, testing and remedial requirements affect the programme. Tell us about essential equipment before the appointment so the arrangements reflect your household’s needs.
Not solely because it is plastic. Its condition, location, protection and suitability for the installation need assessment. A recommendation should explain the reason for change, not rely on the enclosure’s material alone.
Not necessarily. A problem in an appliance or circuit can remain. Diagnosis comes first; replacement is appropriate only where the findings justify it.
No. The design must reflect the circuits, equipment and applicable requirements. We explain the chosen protection and avoid treating every home as an identical package.
Potentially, subject to assessment. Relocation can involve cable alterations, different access arrangements and making-good. It should be specified and priced separately from a straightforward replacement in the existing position.
We can assess the proposed work. Access to shared equipment, building-management requirements and responsibilities must be established before the installation date.
The electrical installation certificate and relevant schedules, together with the applicable Building Regulations compliance documentation. We explain the scope covered and any outstanding recommendations at handover.
Your postcode, property type, reason for the upgrade and details of planned electrical work. A photograph taken safely from outside the enclosure can help; do not remove covers or expose wiring.
