Assessment, installation, testing and certificationStandalone replacements · Planned home improvements

Domestic Installer
Scheme

We assess the starting point, specify the replacement and agree how the changeover will be managed. From the first discussion to the circuit labels and certificates, the work is organised around your property and the way you use it.

Whether this is a standalone replacement in a Brackenbury Village house or part of an apartment refurbishment near Brook Green, we help you understand what needs changing, what can remain and what the quotation covers.

01 · First, define the reason for change

Start with the outcome you need

A new consumer unit should be specified with a clear purpose. You may need a different protective arrangement, room for planned circuits or a replacement for equipment that is damaged or no longer suitable.

Sometimes the enquiry starts with a problem: a switch that keeps tripping, unclear circuit labels or concern about an old fuse box. These are reasons to investigate, not enough information to select a replacement from a photograph.

Before discussing equipment, we ask what has prompted the work. Is the home staying as it is? Is a kitchen being replaced? Will electrical alterations happen in stages?

Those answers help shape a proportionate scope. A smaller, clearly defined job may be appropriate; other installations need additional work identified before a date is booked.

02 · Assessment before a specification

Does the fuse box need replacing—or is the problem elsewhere?

Older fuse box in a timber-lined electrical cupboard before assessment — Start with what is there. Understand what needs to change.

The consumer unit distributes power to the property's circuits and houses protective devices. Its condition matters, but so does the installation connected to it.

An older fuse box or plastic enclosure is not, on its own, proof that replacement is compulsory. Its condition and suitability require assessment. Electrical Safety First's replacement guidance explains this distinction.

Likewise, a faulty appliance or damaged cable can cause tripping independently of the board. Our guide to why an RCD keeps tripping explains why finding the cause comes first.

We separate three possible outcomes:

Retain the board and address a specific fault.
Replace the consumer unit with suitable existing circuits retained.
Include repairs or wider wiring renewal where the findings justify it.

If more substantial renewal is needed, we discuss house and flat rewiring in Hammersmith as a distinct scope.

03 · Know what your quotation includes

Consumer unit replacement cost in Hammersmith

The useful question is not simply how much a new board costs. It is what it will take to complete the replacement properly in your home.

We prepare the quotation around the circuits, equipment, working position and associated work. An accessible board with suitable existing wiring presents a different scope from a relocation involving cable alterations and a fitted cupboard.

Your quotation should identify:

The consumer unit and protective devices being supplied.
Installation, inspection, testing and circuit identification.
Known repairs and any required earthing or bonding work.
New circuits or alterations included in the price.
Arrangements for isolation and any external appointments.
Included or excluded joinery, decoration and making good.
Certification, notification and the VAT position.

We discuss identified extras before you commit. If further issues emerge during the work, we explain the findings and agree the next steps, including necessary safety measures.

This makes it easier to compare quotations on their actual scope. A lower headline price is not necessarily a lower price for the same completed job.

Ask PEP to review your replacement requirements.

04 · A standalone upgrade, or part of a bigger plan

Plan the board around the work you already have in mind

A consumer unit can be replaced as a self-contained project. You do not need to be renovating the house to book the work.

However, if you are already planning alterations, that information belongs in the discussion before the board is chosen. A new kitchen layout, additional appliances or changes to heating controls may affect the circuits and protective arrangement.

We can coordinate the replacement with our wider electrical services in Hammersmith. For a kitchen project, our guide to planning kitchen electrics helps identify decisions worth making early.

Allowing sensible spare space may help accommodate future circuits. It does not increase the capacity of the electricity supply. Any additional demand still needs assessment.

The aim is to allow for known plans without selling you equipment or work that the project does not need.

05 · Access, working space and retained finishes

Working in Hammersmith houses, converted flats and managed buildings

Agree the access as well as the appointment

In a converted flat, the consumer unit may be inside the home while the meter or isolation equipment is elsewhere. Communal cupboards, restricted working hours and managing-agent procedures can affect preparation.

Tell us who controls access to those areas. If permissions or appointments are needed, they should be arranged before the installation visit.

A quotation for your flat's board does not automatically include work to communal electrical distribution or equipment belonging to another party. UK Power Networks explains the different responsibilities around supply equipment.

Check the working position and surrounding finishes

In a house or maisonette, the practical issue may be the position of the board: inside joinery, beneath the stairs or beside finishes you intend to retain.

We consider access for installation and future use. If the proposed replacement needs more space, a cupboard alteration or a different position, that becomes part of the scope discussion.

We also coordinate with your builder where electrical work forms part of a wider refurbishment. Deciding the board position before joinery is finished helps avoid an unnecessary clash between trades.

06 · More than a new enclosure

Protection selected for your installation

Completed metal consumer unit with labelled protective devices on a blue-grey wall — A considered specification. Clear circuit identification.

A consumer unit is an assembly of compatible equipment, not just an enclosure with spare slots.

RCBOs combine residual-current protection with protection against overcurrent for an individual circuit. Individual protection can reduce the number of circuits affected by certain faults, though it does not promise an interruption-free home.

RCD protection responds to certain leakage currents. An RCD alone does not provide overload protection; the complete protective arrangement matters.

Surge protective devices help limit transient overvoltages. They perform a different function from an RCD or RCBO.

Arc fault detection is considered where required or appropriate to the installation.

We explain the proposed specification in practical terms: how the circuits are arranged, what the devices do and what capacity has been allowed for agreed future work. NICEIC's consumer unit guide provides an introduction to these protective functions.

07 · Before the power goes off

Before installation day: make a practical power-off plan

Replacing a consumer unit requires a planned interruption to the supply serving the work. Inspection and testing also form part of the programme; fitting the enclosure is not the whole appointment.

We discuss the expected interruption after reviewing the installation. Before agreeing the date, tell us about anything that depends on electricity being available:

Working from home and internet access.
Refrigeration, alarms and access systems.
Heating and hot-water controls.
Any essential or medically necessary powered equipment.

Where continuity is critical, suitable arrangements need to be agreed in advance. Temporary power should never be assumed to be included.

There also needs to be clear access to the working area. You can move ordinary stored items away if safe, but leave electrical covers, seals and supply equipment untouched.

If suitable isolation is not already available, arrangements with the relevant provider may be needed. We identify this during preparation rather than treating every installation as ready for an immediate changeover.

08 · The changeover, step by step

How the replacement is carried out

Electrician aligning the metal front cover on a replacement consumer unit — The specified replacement. Fitted with care.

Confirm the agreed work
We review the scope, access and planned interruption with you. For a refurbishment, this includes confirming which associated work is happening during the same visit and what belongs to a later phase.
Complete the installation
The installation is safely isolated, the existing board is removed and the specified replacement is fitted. Agreed associated work is carried out, with attention to the cable arrangement, identification and surrounding working area.
Verify before handover
Inspection and testing are part of completing the job. If a finding prevents safe reconnection, it is explained; an unsafe circuit is not put back into service simply to meet a finish time.
Explain the result
We take you through the circuit identification, relevant user information and any outstanding recommendations. You should leave the process knowing what changed and where the records are, not just that the lights are back on.

09 · Test, record and explain

Testing, certification and Building Regulations

Electrician checking an installation with a yellow tester connected to a socket — Testing is part of completing the installation.

PEP is registered under the NICEIC Domestic Installer Scheme. The replacement work is designed, installed and verified against the applicable requirements of BS 7671.

An Electrical Installation Certificate records the completed work, supported by the relevant inspection schedules and test results. It identifies the extent of the work; it does not mean that all retained wiring has been replaced. NICEIC explains the certificate required for a new consumer unit.

Consumer unit replacement in a dwelling in England is notifiable under the Building Regulations. We arrange the relevant notification through our registration scheme. The Building Regulations compliance documentation is separate from the Electrical Installation Certificate. Approved Document P sets out the requirements.

Keep the documents together with the property's electrical records. They help establish what was done and provide useful information when future alterations are planned.

Before you book

Questions about fuseboard replacement

Can I replace the consumer unit without rewiring the property?

Yes, if the existing circuits are suitable for reconnection. Selected repairs may be enough where defects are found. We explain the distinction between replacement, repairs and rewiring; our consumer unit replacement or full rewire guide explores the decision.

How long will I be without electricity?

We give an expected power-off programme once the scope and access arrangements are understood. Testing, associated work and any faults discovered affect completion. Please tell us about essential equipment before the appointment is agreed.

Can I stay at home during the work?

Often this can be arranged, provided the working area is kept clear and the power interruption is manageable for you. Discuss home working, children, pets and any essential equipment with us beforehand so the visit can be planned sensibly.

Do I need an EICR before replacing the board?

Electrical Safety First recommends an EICR before a planned replacement. If this is declined, an appropriate pre-work survey is still required. Assessment cannot simply be skipped. The completed replacement receives an installation certificate, which serves a different purpose.

Will you reconnect everything if a fault is found?

Not where doing so would be unsafe. We explain the affected circuit, the findings and the proposed response. Any required disconnection and remedial work must be addressed as part of completing the job safely.

Can the new board go inside the existing cupboard?

Possibly. We need to check the space, access, proposed enclosure and cable arrangement. A replacement can differ in size from the existing board; cupboard alterations or relocation should be identified and priced, not assumed.

Does a plastic consumer unit automatically need changing?

No. Material alone does not decide whether an existing board needs replacement. The assessment considers its condition and the installation. Requirements applying to new work are not a blanket instruction to remove every older plastic board.

Will a larger board let me add more powerful appliances?

Not by itself. Extra space allows for additional protective devices, but the proposed circuits, demand and supply arrangements must still be suitable. Tell us about planned appliances before the replacement is specified.

Can you quote for just the fuseboard replacement?

Yes. We undertake standalone replacements as well as work coordinated with refurbishments. The quotation will identify the replacement and associated work needed for your installation, without assuming that you want a wider renovation.
