Board already flagged
A survey, EICR or previous electrician has raised the board. The next step is to understand what was flagged and whether replacement is actually the sensible response.
Consumer unit replacement in NW London
Best when the fuse box looks dated, the board has already been flagged, trips keep recurring, or you want the first step checked before wider electrical work. Sometimes replacement is the right answer. Sometimes the better first step is fault finding or an EICR. The point is to work out the sensible next step before the scope grows.
Board scope checked early • Registered electrical delivery if needed • Clear paperwork
Board scope first
Check whether replacement is the right next step
A consumer unit quote starts with the reason the board is being reviewed. Board photos, postcode and the current symptom help separate replacement, fault finding, an EICR or wider electrical planning before the scope grows.
Repeat trips or heat
Recurring trips, heat, marks or burning smells need diagnosis first. Sometimes the board is part of the answer; sometimes a local fault or repair comes before replacement.
Planned wider electrical work
Renovation, extra circuits, EV/heat-pump discussions or wider upgrades can change the board scope, so the board is checked before other electrical work is priced or booked.
Where replacement goes ahead, it is planned through registered electrical delivery with relevant testing, certification/notification and handover explained before booking. If the job needs a Part P registered partner electrician or registered electrician, I’ll explain who handles that part and what paperwork belongs to the job.

Review highlights
What's included
A replacement is not just a box change. The work covers the first scope check, how the registered installation is handled, power-off planning, testing, labelling and a plain-English handover.
When you might need this
These are the common reasons people start asking about a new consumer unit. They do not all mean “replace it immediately”, but they are good reasons to get the scope checked properly.
Scope, installation and handover
Usually this means photos and context first, then a proper scope and quote, then planned installation, testing and certification through registered electrical delivery.
Pricing approach
Consumer unit replacement is quoted as a project once the board, existing setup and likely scope are understood. It does not sit inside standard small-job hourly pricing. If the honest first step is fault finding or an EICR instead, I’ll say so before anything is booked.
FAQs
Do all old fuse boxes need replacing?
No. Age alone does not decide it. The first check looks at the condition of the board, the protection it provides, any report comments and what other work is planned.
Do you carry out consumer unit replacement yourself?
Consumer unit replacement uses registered electrical delivery where required. I’m not personally registered with a competent person scheme, so I do not self-certify notifiable domestic work. If the job goes ahead, the Part P registered partner electrician or registered electrician involved handles that part, while you still deal with me directly for the first check, scope, quote and handover.
Will the power be off during the work?
Yes. There is a planned downtime window on the day, confirmed in advance so you can prepare anything that needs power.
Do I receive certification documents?
Yes. Any certification and related paperwork are issued through the registered electrical delivery used for the installation.
Can photos tell you whether replacement is likely?
Photos are the best first filter and often enough to sense-check the likely next step. Sometimes the honest next step is fault finding or an EICR first.
What should I send for a quote or first check?
Send your postcode, one photo of the full board, one closer photo of the labels, and a short note on any tripping, heat, report comments or planned works.
Need the board checked before you commit to replacement?
Send your postcode, board photos and the reason the board is under review. I’ll tell you whether this looks like consumer unit replacement, electrical fault finding first, or an EICR before wider work.
