Electrical guides & practical advice
67 plain-English guides on faults, costs, certificates, systems and home projects — written from real domestic jobs across Buckinghamshire, Oxfordshire and Surrey.
Faults & symptoms
What common household electrical symptoms usually mean, what you can safely check yourself, and when to stop and call an electrician.
- Why Your Fuse Box Keeps TrippingA consumer unit that trips is doing its job — the question is what it keeps objecting to.
- Flickering Lights: Causes and FixesFlicker is a symptom with a short list of causes — and one of them is genuinely worth acting on quickly.
- Burning Smell From a Socket or SwitchThis is the one symptom on this site where our advice is to stop using the circuit today.
- RCD Will Not Reset: How to Find the CircuitAn RCD that will not stay in is holding back a live earth-leakage fault somewhere on its side of the board.
- Sockets Not Working on One WallDead outlets in a group almost always mean one broken connection, not several failed sockets.
- Half the House Has No PowerA house split neatly in two is a board-level symptom, not a coincidence.
- Outdoor Sockets and Garden Lighting That TripGarden electrics live outdoors, and outdoors is where every weakness in an installation eventually shows.
- Electric Shower Tripping the ElectricsShowers combine the highest load in most houses with the wettest environment — so faults show up early.
- Buzzing Switches, Dimmers and FittingsSome buzz is harmless electronics; some buzz is a connection you should not ignore.
- Bathroom Extractor Fan ProblemsA fan that does not clear steam is a damp problem waiting to become a decorating problem.
- Why Does My RCD Keep TrippingAn RCD trips because it detected earth leakage. It is doing its job.
- How Electricians Actually Find Electrical FaultsFault finding is a process of elimination, and the more information you can give at the start, the fewer steps it takes.
- Intermittent Electrical Faults and How to Pin Them DownAn intermittent fault is not a mystery, it is a fault with a condition attached. Finding the condition is the job.
- The Board Trips When I Plug Something InIf it trips the moment you plug something in, you have already narrowed the search enormously.
Cost, process & paperwork
How domestic electrical jobs are priced, how long they take, what happens on the day, and which certificates you should end up holding.
- What Affects the Cost of a Consumer Unit UpgradeTwo identical-looking boards can be very different jobs once the cover comes off.
- What Drives the Cost of a House RewireA rewire is priced on access and disruption far more than on cable.
- How Long a Rewire Actually TakesThe electrical work is only part of the calendar — plaster drying is often the longest single item.
- What Happens During an EICRAn EICR is a structured assessment, not a look around — and knowing the routine makes the day easier.
- EICR Codes C1, C2, C3 and FI ExplainedFour codes decide whether your report is satisfactory and what you must do next.
- Electrical Certificates: Which One You Should GetThe right certificate depends on whether work was new, altered or merely inspected.
- How to Choose a Domestic ElectricianThe cheapest quote and the clearest quote are rarely the same document.
- Adding Sockets Instead of Living With Extension LeadsExtension leads are a symptom: the room has fewer outlets than the way you live in it.
- What Electrical Work Needs Building Control Sign OffSome electrical work has to be notified to building control. Plenty does not.
- Part P Explained for HomeownersPart P is about electrical safety in dwellings. It is shorter and simpler than most people expect.
- How Much Does It Cost to Wire an ExtensionExtension electrics are priced by scope and access, not by floor area alone.
- What a Home EV Charger Installation CostsThe unit is a fixed price. Everything around it is where quotes diverge.
- Partial Rewire or Full Rewire: How to DecideA partial rewire is the right answer more often than people think, and the wrong one more often than they hope.
- What an EICR Costs and What You Get for ItThe cheapest report is rarely the one you want, because a proper EICR is priced by how long testing genuinely takes.
- How Electricians Price Domestic WorkTwo quotes for the same job are usually pricing two different jobs. The trick is spotting where they diverge.
- What It Costs to Add a Socket or TwoThe socket costs a few pounds. Everything else is about how hard it is to get a cable there.
Systems & comparisons
Plain-English comparisons of the parts and systems that go into a modern domestic installation, so you can choose with your eyes open.
- RCD vs RCBO: What the Difference Means at HomeThe difference is not protection quality — it is how much of your house goes dark when something leaks.
- Metal and Plastic Consumer Units ComparedThe move to non-combustible enclosures was a response to real failures, not a fashion.
- Surge Protection Devices in a Domestic BoardAn SPD protects connected equipment from transient voltage spikes — not from every electrical mishap.
- Arc Fault Detection Devices (AFDDs) at HomeAFDDs target a failure mode that other protective devices genuinely do not see.
- LED Downlights, Spotlights and Retrofit LampsThe right choice depends on whether you are replacing lamps or replacing a ceiling's worth of old transformers.
- Getting LED Dimming RightMost LED dimming complaints are a compatibility problem, not a faulty lamp.
- Smart Lighting: Wired, Wireless and HybridThe most important smart lighting decision is where the intelligence lives.
- Ring and Radial Socket CircuitsBoth designs are valid; the choice affects cable, protection and how faults present.
- USB Sockets Versus Plug-In ChargersBuilt-in USB is about tidiness and permanence rather than raw charging speed.
- Planning Outdoor and Garden LightingGood exterior lighting is mostly about restraint, direction and IP ratings.
- Do I Need a New Consumer Unit for an ExtensionSometimes yes, often no. Testing answers it rather than guesswork.
- Planning Lighting for an Open Plan Kitchen ExtensionOpen plan rooms do three jobs at once, so the lighting has to as well.
- EV Charger Installation at Home: How It Actually WorksMost of the job happens before anyone drills a hole: the survey decides whether the installation is simple or awkward.
- Planning the Wiring for a Smart HomeThe cheapest time to future proof a house is while the walls are open. The second cheapest is never.
- Smart Switches and Dimmers: What Actually WorksThree products solve the same problem in different places, and choosing the wrong one is why smart lighting annoys people.
- Downlight Spacing and Layout That Actually WorksMost bad downlight schemes are not too dim. They are evenly spaced in the wrong places.
- Under Cabinet Kitchen Lighting Done ProperlyWorktop lighting is the single upgrade that makes a kitchen feel finished, and it is usually done as an afterthought.
- Solar and Battery Storage: The Electrical SideThe panels are the visible part. The connection into your existing installation is where the practical decisions are made.
- Do I Actually Need a Consumer Unit Upgrade?An old board is not automatically a dangerous board, but some of them genuinely are.
Property types & projects
Electrical planning notes for particular property types, renovation projects and household situations across Buckinghamshire and beyond.
- Landlord Electrical Duties and the Five-Year EICRRented property has a defined inspection cycle and a defined deadline for remedial work.
- Electrical Checks Before You Buy a HouseA homebuyer survey will note the electrics; it will not test them.
- Rewiring Period and Character PropertiesIn a period property the wiring is the easy part; getting to it without damage is the job.
- Electrics for a Kitchen RefitThe kitchen carries more electrical load than any other room, and gets the least planning time.
- Electrics for a Loft ConversionA loft conversion adds rooms, load and — importantly — fire detection requirements.
- Wiring a Home ExtensionAn extension's electrics are only as good as the installation they connect to.
- Powering a Garden Office or OutbuildingA garden office is a small installation in its own right, not a long extension lead.
- Electrics for Working From HomeMost home offices were bedrooms, and bedrooms were wired for a lamp and an alarm clock.
- Electrical Work in Flats and MaisonettesIn a flat, the boundary between your installation and the building's is the first thing to establish.
- Bathroom Electrics and ZonesBathrooms are a special location, and the rules are about water and distance rather than paperwork for its own sake.
- When Does a House Need RewiringAge is a clue. Condition and test results are the evidence.
- Electrics for a Kitchen Extension, Start to FinishA kitchen extension is the most electrically dense room most homes will ever gain.
- Rewiring During a Renovation, How to Sequence ItA renovation is the cheapest time a house will ever be rewired.
- EV Charging for Flats and Shared DrivewaysThe electrical problem is usually simple. The ownership and metering questions are the hard part.
- Garden Lighting Installation: A Practical GuideA garden lit well uses fewer fittings, aimed lower, than most people expect.
- Security Lighting and Sensors That Do Not Annoy YouA floodlight that comes on forty times a night stops being security and becomes background noise.
- Rewiring a House You Are Still Living InIt is entirely possible to live through a rewire. It is much easier if the phasing is agreed before anyone lifts a floorboard.
- Moving, Raising and Replacing SocketsThe best time to move a socket is the week before you decorate, not the week after.
