The electrical work we take on
Pro-Detect covers the full range of domestic and small commercial electrical work: full and partial rewires, consumer unit replacements, additional circuits, socket and lighting installations, fault finding, earthing and bonding upgrades, inspection and testing, and remedial work following a report.
Sixteen-plus years on site, much of it subcontracting for other firms, means most faults are recognised rather than guessed at. That matters commercially: diagnosis time is the expensive part of any electrical call-out, and experience shortens it.
The other half of the job is communication. You should know what is wrong, what has to be done now, what can wait, and what it will cost before work starts. Nothing gets opened up, discovered and re-priced mid-job without a conversation first.
Who it is for
- Homeowners with an ageing installation, a fuse board that keeps tripping or lighting that flickers.
- Buyers and sellers who need an installation inspected and reported on.
- Landlords needing periodic inspection and remedial work.
- Small commercial premises, workshops and units needing reactive and planned electrical work.
When it is needed
- Breakers tripping, sockets scorching, lights dimming or buzzing.
- A rewireable fuse board, no RCD protection, or a board over 20 years old.
- An extension, loft conversion, kitchen or bathroom needing new circuits.
- An inspection report listing coded faults that need correcting.

What happens when electrical faults are left alone
Electrical faults do not stabilise. A loose connection generates heat, heat degrades insulation, degraded insulation increases leakage, and leakage eventually causes either a nuisance trip or a fire. The sequence is slow enough that people learn to live with the early symptoms.
The warning signs are consistent: warm or discoloured accessories, a smell of hot plastic, breakers that trip when it rains, lights that dim when the kettle boils. Each of those is a measurable fault with a cause, not a quirk of an old house.
There is a financial dimension too. An installation with no RCD protection, no main bonding or an unsatisfactory inspection report can complicate insurance claims and delay a house sale. Fixing it after a buyer's survey, under time pressure, always costs more than fixing it on your own schedule.
Mistakes we see most often
- Resetting a tripping breaker repeatedly instead of finding the fault.
- Adding sockets or a garden supply on an existing circuit with no load calculation.
- Using a general builder or handyman for notifiable work in a kitchen or bathroom.
- Replacing a consumer unit without upgrading inadequate earthing and bonding.
- Ignoring C1 and C2 codes on an inspection report because the lights still work.
How the work runs, step by step
The same sequence every time, so you always know what happens next and who is doing it.
Attend and inspect
We look at the installation itself: board, earthing, bonding, cable condition and the circuit that is actually causing the problem.
Diagnose and explain
Testing establishes the cause, and you get a plain explanation of what is wrong, what is urgent and what is optional.
Agree the work in writing
Scope and price are confirmed before work starts. Larger jobs get a written quote within 7 days of the free survey.
Carry out the work
Installed to BS 7671, with dust control, safe isolation and the property left tidy at the end of each day.
Test, certify and hand over
Circuits are tested, results recorded, certification issued for the work carried out and the outcome explained before we leave.
What you get out of it
Faster diagnosis
Sixteen-plus years of fault finding means less time billed working out what a previous installer did.
Available 24/7
Genuine round-the-clock availability, 365 days a year, for urgent electrical problems.
Tested and certified
Work is tested and certificated, so you have documentation for insurers, buyers and tenants.
No mid-job surprises
Scope and cost are agreed before tools come out; changes are discussed, not assumed.
Tidy on site
Dust control, protected floors and a clean finish, a point our customers raise in their reviews.
One point of contact
You deal with Llewys throughout, from first call to final certificate.
Electrician in detail
Consumer units and circuit protection
A modern board provides RCD or RCBO protection per circuit, surge protection where appropriate, and a metal enclosure. The advantage of RCBOs over a split-load board is isolation of faults: one circuit trips, the rest of the house keeps running, and diagnosis is immediate rather than a process of elimination in the dark.
A board change is never only a board change. Earthing arrangement, main protective bonding to gas and water, the condition of existing circuit cabling and the incoming supply all have to be verified first, because a new board on an unsound installation simply reveals faults that were previously being masked.
Rewires, partial rewires and new circuits
A full rewire replaces circuit cabling throughout and is the right answer for properties with rubber or fabric-insulated cable, no earth on lighting circuits, or decades of undocumented additions. It is disruptive, and it is planned room by room so you keep power and heat where possible while it happens.
Many houses need less than that. A partial rewire replaces the circuits that are actually at end of life (often the lighting or an old kitchen ring) and leaves sound circuits alone. The survey is what separates the two, and it is free.
New circuits for kitchens, bathrooms, extensions, garden offices, workshops and outbuildings are designed around load, cable route, protection and the capacity of the existing supply, not simply spurred off whatever is nearest.
Inspection, testing and reports
An Electrical Installation Condition Report records the state of a fixed installation and codes faults by severity: C1 for danger present, C2 for potentially dangerous, C3 for improvement recommended, and FI where further investigation is needed. Rented property is inspected on a defined cycle; owner-occupied property is usually assessed periodically or at sale.
We carry out inspections and we also put right coded faults from other people's reports. Where a report is vague, we will test to establish what the code actually relates to before quoting remedial work; nobody should be paying to fix an undefined item.
Lighting, sockets and outdoor electrics
Interior lighting design covers circuit layout, switching arrangement, dimming compatibility and the reality that LED loads behave differently from the filament loads older circuits were designed around. Retrofitting LEDs onto old dimmers is a common cause of flicker and buzz with a straightforward fix.
Outdoor work (garden lighting, garage and outbuilding supplies, hot tub circuits, external sockets) needs correctly rated equipment, buried armoured cable at proper depth, RCD protection and weatherproof terminations. It is the area where DIY and general-trade work most often falls short and where wet Welsh winters find every weakness.
Domestic versus commercial
Domestic work is single-phase, load-modest and scheduled around a household. Small commercial sites bring three-phase supplies, distribution boards, machinery loads, emergency lighting and downtime cost into the picture.
For commercial customers the real currency is uptime. Because Pro-Detect operates 24/7, isolation and switching work can be done overnight or at weekends so trading is not interrupted.
Electrician: your questions answered
How much does an electrician cost in Caldicot?
Small works are priced per job once we know what is involved; larger works are quoted in writing within 7 days of a free survey. You will always know the price before work starts.
Do you attend emergencies?
Yes. Pro-Detect is available 24 hours a day, 7 days a week, 365 days a year.
How long does a rewire take?
It depends on property size, occupancy and whether it is full or partial. The programme is set out in your quote so you can plan around it.
Do I need a new consumer unit?
If your board is rewireable, has no RCD protection or is over twenty years old, it is usually due. We inspect the earthing, bonding and circuits first rather than assuming a replacement.
Will I get certification for the work?
Yes. Work is tested and certificated, and the results are explained before we leave.
Can you fix faults from an inspection report?
Yes. We carry out remedial work on reports from any inspector, and we will test first where a coded item is not clearly described.
Why does my breaker keep tripping?
Usually a faulty appliance, moisture ingress, a damaged cable or accumulated earth leakage across several circuits. Testing separates the causes quickly instead of guessing.
Do you work for landlords?
Yes: inspections, remedial work and reactive repairs across Monmouthshire, Newport and Bristol.
Can you do electrical work alongside solar or security work?
Yes, and it usually saves money. Combining a board upgrade with a solar, EV charger or alarm installation avoids paying twice for access and set-up.
Which areas do you cover?
Caldicot, Rogiet, Magor with Undy, Chepstow, Devauden and Catbrook, Monmouth, Abergavenny, Usk, Newport and Bristol.
