Power that
stops being
a question

We are a two-van electrical firm working across the Ashfold valley. Every job gets a written scope before anyone lifts a floorboard, a booked window instead of a vague morning, and test results in your hands the day we finish.

What we cover

Jobs, and how long you lose power for


Typical visit lengths taken from our own job sheets. Anything longer than a day is staged so kitchens, bathrooms and tills keep working overnight.

Homes & flats

Fault-finding & tripping circuits

60–90 min

Circuit-by-circuit isolation to find the actual fault, not a guessed replacement. You get the cause in writing.

Consumer unit upgrade

Half day

New board with RCBO protection, a labelled circuit list, and power back on before we leave.

Full or partial rewire

3–8 days

Staged room by room with dust sheets and a daily tidy. Old rubber or fabric cable is removed, not buried.

EV charger install

3–4 hours

Load check first, so the charger and the shower can share a supply without nuisance tripping.

Garden power & outdoor lighting

Half day

Armoured cable at proper depth, weatherproof points, switched or timed from inside the house.

Inspection report (EICR)

2–4 hours

Full test schedule with plain-English notes on what must be fixed now and what can wait.

Shops, studios & workshops

Lighting layout & dimming

Survey 45 min

Levels measured on site so display, task and back-of-house lighting are not all on one dumb switch.

Three-phase supply checks

2 hours

Balance and spare capacity measured before you order machinery or a bigger oven.

Desk power & data containment

Half day

Floor boxes and trunking set out against your furniture plan, so nothing trails across a walkway.

Emergency lighting & testing

1–2 hours

Duration test run, logbook entries completed, failed fittings listed with replacement options.

Plant & kitchen equipment wiring

By scope

Isolators within reach, correct protection for motor loads, labelled clearly for your cleaning team.

Fit-out first fix

By scope

We work to the shopfitter’s programme and confirm second fix dates in writing up front.

Not sure which of these your problem is? Describe what the lights and the board are doing — that is usually enough for us to name the job.

Describe the job

Standards

What we check before we leave


A finished job is a tested job. These checks happen on every visit, whether it is one socket or a whole house.

  • Continuity and polarity on every circuit we touched, plus the ones sharing a board with it.
  • Insulation resistance recorded per circuit, so the next test has something to compare against.
  • RCD trip times measured with a tester, never assumed from the label on the front.
  • Earthing and bonding at the water and gas entry checked, and upgraded if it is undersized.
  • Board labelling rewritten properly — room names, not “spare” in faded biro.
  • Site left clean — offcuts bagged, dust sheets lifted, and a walk-round with you before the van is packed.

Paperwork you keep

  • Minor works or installation certificate with the full schedule of test results
  • A labelled circuit list for the new or existing board
  • Photographs of anything that will end up hidden behind plaster or boards
  • A short note of what we would do next, and roughly when

How it runs

From first message to certificate


Four steps, with no surprises in the middle. You know the price and the dates before any work starts.

01

Survey note

We come and look. Board age, cable type, earthing arrangement and the route a new circuit would take all get noted, along with the awkward bits you already know about.

02

Written scope and price

A fixed price against a written scope: what is included, what is excluded, and what we would leave for later. If the job is smaller than you feared, we say so.

03

Booked window and isolation plan

Dates confirmed with arrival times, plus which circuits go off when. Fridges, freezers, routers and shop tills are planned around before the first screw comes out.

04

Test, label and hand over

Everything tested and labelled, the certificate written up on site, and a walk of the job together so nothing is discovered a week later.

Is it urgent?

Switch it off now, or book it in?


Read this before deciding how quickly you need us. If you are unsure which column you are in, treat it as the first one.

Stop using the circuit

Turn the affected circuit off at the board — or the main switch, if you cannot tell which one it is.

  • A hot, browned or smoke-smelling socket, switch or light fitting
  • A breaker or RCD that trips again the moment you reset it
  • Buzzing, crackling or scorch marks at the consumer unit
  • Any shock or tingle from a tap, appliance or metal sink
  • Water that has reached a fitting, a socket or the board itself
  • Cable damaged by a nail, screw, spade or rodents

Plan it properly instead

Nothing is getting worse today, so you will get a better job by giving it a proper slot.

  • One dead socket or light while everything else behaves normally
  • Too few sockets, or extension leads that have become permanent
  • An old board you would like replaced before you redecorate
  • Outside lights, a garden supply or an EV charger
  • An inspection report for a tenancy, a sale or an insurer
  • Lighting you want redesigned as part of a bigger project

Supply, meters and capacity

The bit that changes the quote


Before you commit to a charger, a bigger oven, a workshop machine or a heat pump, the incoming supply needs checking. We measure what is actually there, then tell you whether load management solves it or whether the supply itself has to be upgraded — and who is responsible for that work.

Questions we get every week

Before you book


Will the power be off all day?

Rarely. Most work is done circuit by circuit, so the rest of the house or unit stays live. A board change needs the main switch off for roughly two to three hours, and we confirm that window the day before so you can plan around fridges, freezers and anything on a router.

Do I need a full rewire or just a new board?

It depends on the cable, not the age of the building. If the existing wiring tests well and the insulation readings are healthy, a new consumer unit with modern protection is often all that is needed. If we find rubber, fabric or heat-damaged cable, a partial rewire of those circuits is the honest answer. The survey results decide it, and we show you the numbers either way.

What paperwork do I actually get?

A certificate appropriate to the work — minor works for small jobs, an installation certificate for new circuits and boards — with the full schedule of test results, a labelled circuit list, and photographs of anything that ends up hidden. Landlords and sellers get the inspection report in a format agents and insurers accept.

Can you fit around a kitchen fitter or decorator?

Yes, and it is usually cheaper that way. First fix goes in before plastering and units, second fix afterwards. Send the other trades’ dates with your enquiry and we will slot our two visits into their programme rather than asking everyone to work around us.

Do you make good the plaster and floorboards?

We lift and refit floorboards, and we fill chases back to a flat, paintable finish. We do not skim whole walls or redecorate — the scope says exactly where we stop, so you can brief a decorator without a gap in the middle.

Is an inspection report the same as a fault-finding visit?

No. An inspection report is a scheduled test of the whole installation that produces a condition record and a list of coded observations. Fault-finding is a targeted visit to trace one specific problem. If a report turns up something that needs attention, we quote for that separately rather than rolling it into the test fee.

How far ahead should I book?

Small works and testing usually land within a fortnight. Rewires and fit-outs are booking four to five weeks out, because they are staged around other trades. Safety faults are handled ahead of planned work — describe what is happening in your message and we will tell you the same day.

Tell us what it is doing


A few lines is plenty. We reply with the likely job, a survey window, and what it would cost to come and look.

Enquiries go straight to the diary. We answer between jobs, so a reply lands the same working day or first thing the next.
