Wiring that behaves the same on the worst day of the year

Fault finding, consumer units, rewires, lighting and charge points across the North Quarter and the boroughs around it. Booked windows, diagnosis before parts, and written notes you can hand to the next trade.

  • Part P notifiable work
  • Two-hour arrival windows
  • Written test results

01 — 04 · The call-out sequence

How a job actually runs

Most hesitation about booking an electrician is about what happens after the van arrives. This is the order we work in, on every job, from a dead socket to a full board change.

  1. 01

    Describe the fault

    Tell us what trips, when it trips, and what was switched on at the time. That detail usually narrows a fault to one or two circuits before we set off.

  2. 02

    A booked window

    You get a two-hour arrival window and a note of what we expect to do in it. If the work needs the supply off, we agree that beforehand.

  3. 03

    Diagnosis before parts

    We test first and quote second. Nothing is replaced on a guess, and if a part has to be ordered you hear the reason and the wait on the day.

  4. 04

    Certificate and notes

    Notifiable work is registered and you receive the certificate plus plain-language notes on anything we flagged but did not touch.

Service index

Six lanes of work

Pick the lane that matches your situation. Visit lengths are the usual case for an average domestic property, not a promise — access, board condition and cable routes move them.

  • Lane 01

    Fault finding & call-outs

    Tripping RCDs, dead circuits, intermittent lighting and burning smells. We isolate the circuit, test it properly and make it safe before anything is rebuilt.

    • Insulation resistance test
    • Circuit isolation
    • Temporary make-safe

    Typical visit
    2–4 hours

  • Lane 02

    Consumer unit upgrades

    Replacing rewireable fuse boxes and older split-load boards with RCBO protection, so one fault takes out one circuit instead of the whole house.

    • Pre-change circuit test
    • RCBO per circuit
    • Main bonding check

    Typical visit
    One day

  • Lane 03

    Rewires & part rewires

    Full or room-by-room rewiring, phased so the property stays liveable. Old rubber and early PVC cable, undersized earths and buried junction boxes are the usual reasons.

    • Phased circuit plan
    • Chase & make good
    • New circuit schedule

    Typical visit
    3–8 days

  • Lane 04

    Lighting design & installation

    Layered lighting for kitchens, stairs and workrooms: switching plan first, fittings second. Dimming is specified against the driver, not guessed at the wall.

    • Switching plan
    • Driver-matched dimmers
    • Outdoor & garden runs

    Typical visit
    1–2 days

  • Lane 05

    EV charge point installation

    Load assessment first: we check what the incoming supply and main fuse can carry, then install with the earthing arrangement the site actually needs.

    • Supply load assessment
    • Dedicated circuit
    • Earthing arrangement

    Typical visit
    Half day

  • Lane 06

    Landlord & pre-sale inspections

    Condition reports for rented and selling properties, with coded observations explained in order of urgency rather than handed over as a list of codes.

    • Condition report
    • Coded observations
    • Remedial priority list

    Typical visit
    3–5 hours

Inspection coverage

What we check, and why it matters

A condition report is not a formality. Here is what gets tested on an inspection visit and what a failure on each line usually means for the property.

Domestic condition report — standard coverage
What we checkWhy it matters
Earthing & main bondingThe path a fault current takes to clear safely. Missing bonding to gas and water is the single most common serious finding in older properties.
RCD / RCBO protectionDisconnection speed on an earth fault. Boards without it rely on a fuse that may not clear quickly enough for someone holding the appliance.
Circuit loadingKitchens and home offices often sit on a ring designed decades before the appliances on it. Overloaded circuits run warm and age fast.
Cable condition & typeRubber, lead and early PVC insulation becomes brittle. Once it cracks at the back of a fitting, a fault is a matter of time rather than chance.
Consumer unit conditionEnclosure material, labelling and whether the circuit schedule matches reality. An unlabelled board makes every later repair slower and riskier.
Accessories & socketsScorching, loose terminals and painted-over faceplates. Heat marks around a socket are always investigated, never simply replaced.
Outdoor & garden circuitsBuried cable depth, gland condition and the rating of outdoor enclosures. Garden runs added informally are a frequent source of nuisance tripping.

Field notes

Five things a board tells you before it fails

None of these mean you need a full rewire. They do mean the installation is asking to be tested rather than ignored.

  • It trips only when the shower runs

    A fault that appears under load usually points at one circuit with degraded insulation or a heating element on its way out — not at the board itself.

  • A faceplate is warm to the touch

    Warmth at a socket or switch means resistance where there should be none, normally a loose terminal. It is a small fix now and a burnt back-box later.

  • The board hums or buzzes

    A steady buzz from an older board often comes from a loose busbar connection. It is worth investigating on the same visit as anything else.

  • Lights dip when an appliance starts

    Brief dimming as a motor kicks in can be normal; repeated, visible dipping across the property suggests a supply or connection issue worth measuring.

  • There is no test button on the board

    If nothing on the board has a test button, the installation has no residual current protection at all. That alone justifies an inspection.

Working method

Plan the switching, then buy the fittings

Most disappointing lighting is not a bad fitting; it is a good fitting on the wrong switch line. We mark up where light is needed for tasks, where it is needed for movement, and where it is only ever needed at night. The circuit follows that map.

The same order applies to charge points and boards: measure the supply, agree the layout, then specify hardware. It is slower on paper and considerably faster on site.

Questions we get weekly

Before you book

Do I actually need a full rewire?

Usually not. A rewire is justified by cable condition and earthing, not by the age of the house. If the circuits test well and only the board is outdated, a consumer unit upgrade with remedial work does the same job for a fraction of the disruption. We will say so when that is the case.

What certificate do I get at the end?

New circuits and board changes come with an Electrical Installation Certificate; alterations to an existing circuit get a Minor Works Certificate; an inspection produces a condition report. Each one is issued with the test results attached, not just a signature page.

Can you work around occupied rooms?

Yes — phased work is the normal way we handle occupied properties. We agree which circuits go dead on which day, keep at least one working socket circuit and the kitchen live wherever possible, and sheet up before chasing walls.

What happens if the fault needs a part you do not carry?

We make the circuit safe, tell you the part, the reason and the expected wait before we leave, and book the return visit then. You are not charged a second call-out for a return on the same fault.

Can a charge point go on an older supply?

Often, but it depends on the main fuse rating, the earthing arrangement and what else draws heavily in the property. We measure before quoting; if load management or a supply upgrade is needed, that is established at the survey rather than discovered on installation day.

How long is a consumer unit upgrade, and is the power off all day?

Plan for a full day. The supply is off for most of it, with power returned circuit by circuit as testing completes. If the pre-change tests find a circuit with a fault, we will not energise it — we explain the options before the board goes back on.

Enquiry

Request a booking window

Tell us what the installation is doing. The more specific the symptom, the more likely the right parts are on the van the first time.

  • Reply: same working day for enquiries before 16:00
  • Survey: free for rewires, boards and charge points
  • Windows: two-hour arrival slots, morning or afternoon
Helpful detail: what trips, when it started, what was switched on, and whether the board has test buttons.

If the situation involves smoke, scorching or a burning smell, switch the circuit off at the board first.
