Start here

Start here if you are not sure which guide to open

Most people are trying to answer one of four things first: what to send, whether the next step still looks straightforward, whether the problem needs diagnosis first, or whether the job is really a broader service-page question.

Start with what is happening

Pick the line closest to your situation. Each one opens the guide that explains it, and every guide links the service page that fixes it.

Before booking

Quote prep, pricing and next-step notes

Start here when the main question is what to send, how the likely price shape works, or whether the job stays on the usual direct small-job path.

Before booking guides

Before booking

These explainers reduce guesswork before anything is booked.

What to send for a fast first answer
  • 2–4 clear photos Photos often give a clearer first answer than a long message.
  • Postcode The postcode confirms coverage, travel fit and how quickly the job can be checked sensibly.
  • Product links or model numbers Already chosen the fitting or device? A product link helps confirm finish, compatibility and likely parts.
  • Short description Plain English is enough: what is happening, where it is, and what changed.
Pricing signals
Compliance and registered electrical delivery
How the booking path usually works
  • Book, test and hand over The job is booked, carried out tidily, checked properly and handed over clearly.
  • Confirm scope The likely next step is confirmed before booking so you know what kind of job it is.
  • Send details Start with the basics so the job can be checked quickly and sensibly.

Existing-home electrical work

Small jobs, fittings and fault symptoms

Use these guides when the work sits on existing wiring and the main question is what has failed, what still looks like a straightforward visit, or when the next step becomes fault finding before parts are changed.

Lighting guides

Lighting and fittings

Use these when the question is a fitting, dimmer, downlight or tidy room update on the same point.

What these guides cover
  • Basic fault checks A basic fault check is the right first check for common lighting and accessory faults.
  • Dimmer checks Dimmer problems are often compatibility problems, not just a bad switch.
  • Downlight swaps Downlights often look simple from below, but size, fire rating, insulation, driver type and bathroom rating can matter.
  • Lights and pendants Like-for-like ceiling light and pendant swaps are often a straightforward small job when the current point, ceiling fixing and new fitting all suit each other.
  • Testing and handover Relevant checks on the finished lighting work, plus a clear handover on how it behaves day to day.
Common reasons to open a lighting guide
  • Buzzing dimmer A buzzing dimmer usually points to compatibility or setup issues, not something to ignore indefinitely.
  • DIY wiring doubt If something looks improvised, half-finished or confusing, stop guessing and get it checked.
  • Failed fitting A failed fitting is one of the most common reasons to book a small lighting visit.
  • Outdoor point swap Replacing an outside light on the same point is often straightforward, but weather rating, seals, cable condition and protection still need checking.
  • Room refresh Not every lighting visit starts with a fault. Sometimes the room simply needs better fittings, calmer light or tidier control.
How a lighting visit usually works
  • Confirm scope The likely scope is confirmed before booking so there is less guesswork on time, product fit and access.
  • Install and test Fit, check and hand over clearly so the lighting works properly and the outcome is easy to understand.
  • Send photos Show the existing fitting, switch position and surrounding ceiling or wall without removing any cover.

Accessory guides

Sockets, switches and small accessories

Use these when plates are loose, worn, awkward or ready for a small practical upgrade.

What these guides cover
  • Back box tidy up Secure loose or skewed plates and tidy the point where the issue stays local to the box.
  • Socket swaps Like-for-like replacement of worn, loose or damaged sockets on existing circuits.
  • Spurs and isolators For fused spurs, switched fused connection units, appliance isolators and similar local control points on home circuits.
  • Testing and handover How finished socket, switch and spur work is checked, explained and handed over clearly.
  • USB socket upgrades Replace a standard socket with a suitable USB-integrated accessory where the current point, back box and product choice all line up.
Common reasons to open an accessory guide
  • After decorating Fresh paint, plaster or tiling can leave socket and switch plates crooked, trapped or loose even when the point still works.
  • Failed isolator A dead or unreliable isolator is small on the surface, but important to diagnose correctly.
  • Loose outlets A loose socket or faceplate is often a small repair, but it is worth sorting before movement, heat or damage get worse.
  • Practical upgrades For a socket, switch or local control point that still works but could be better matched, easier to use or more practical day-to-day.
  • Sticky switches A sticky light switch or crackling wall switch is often a small accessory fault, but it should not just be forced and ignored.
How accessory jobs usually work
  • Confirm accessory scope Before booking sockets, switches, spurs or similar points, Willesden Smart Homes confirms whether the work still looks like a focused visit and what details may change the scope.
  • Replace and test This is the on-site finish of a straightforward accessory visit: carry out the agreed replacement neatly, check the worked-on points, and explain any next step if the real condition changes the scope.
  • Share job list List each socket, switch, spur or isolator so grouped accessory work can be scoped together.

Repair guides

Repairs and everyday fixes

Use these when one known point, or a small cluster of everyday faults, needs putting right without turning the job into a bigger project.

What these guides cover
  • Accessory repairs For fixed switches, sockets, pull cords, fused spurs and similar accessories on existing circuits.
  • Fans and spurs For extractor fans, fan isolators, switched fused spurs and other small spur-fed points on existing circuits.
  • Targeted fixes For one dead socket, awkward switch, fused spur or local point that still looks like a contained fault rather than a wider electrical problem.
  • Small parts For the minor components that often fail first: pull cords, lampholders, connection units, plates and similar parts.
  • Test and explain After an electrical repair, the point that was worked on should be checked properly and the result explained clearly.
Common reasons to open a repair guide
  • Failed accessory Dead socket, failed switch, hot faceplate or faulty fused spur? This is often a local repair, but signs of heat or damage should not be ignored.
  • Fan not running If a bathroom or utility extractor fan has stopped working, the fault may be the fan, the isolator or the local switching.
  • Intermittent power Power that cuts in and out at one point or small area usually needs diagnosis, not repeated resetting or random part swaps.
  • Multiple small faults Several small electrical faults can often be grouped into one focused visit, but the pattern still needs judging properly first.
  • Issue after change If something stopped working after a recent change, the first job is to check the altered point properly rather than keep trying different parts.
How repairs usually work
  • Describe issues Describe which point has failed, what changed and whether the issue is constant or intermittent.
  • Prioritise faults Work out what needs isolating now, what should be booked soon, and what can usually wait.
  • Repair and verify Once the likely fault is clear, the next step is a tidy local repair, relevant checks and a plain-English handover so you know what happens next.

Fault-finding guides

Fault finding and recurring trips

Use these when the cause is not yet clear, the trip keeps returning, or a point feels wrong and needs fault finding before parts are changed.

What fault finding includes
  • BS 7671 checks Relevant checks on the affected point or circuit help show whether the fault stays local or needs a wider next step.
  • Dead points and trips Dead socket, dead light or repeated trip? This guide helps you tell the difference between one local fault and something wider that needs diagnosis first.
  • Findings explained Fault finding is only useful if you understand what was found, what it affects, and what the sensible next step is.
  • Safe small repairs Once the fault is confirmed as local, the repair can often be handled neatly in the same visit.
  • Step testing Narrow the fault down in a safe order instead of resetting breakers or swapping parts and hoping.
Common symptoms that point to fault finding
  • Failed light switch If a light switch is not working, only works some of the time or feels wrong to use, the fault may be local to the switch - but not always.
  • Fan or fused spur issues When a bathroom fan or fused spur seems dead or intermittent, diagnosis usually comes before replacement.
  • Hot socket Heat, scorch marks or burning smell around an accessory should be checked promptly.
  • RCBO or RCD trips If the same RCBO or RCD keeps tripping, stop repeatedly resetting it.
  • Smart kit issues When a smart device starts misbehaving, the first step is to separate local power and wiring issues from app or setup problems.
How a diagnostic visit usually works
  • Diagnostic visit The visit focuses on isolating the real cause rather than throwing random parts at the problem.
  • Repair and verify Once the fault is isolated and stays local, the point can often be repaired, checked and handed over clearly.
  • Share symptoms Note the symptom, what trips or stops working, and whether the fault returns after a reset.

Practical smart-home help

Heating control, entry awareness and outside lighting

These guides suit practical upgrades where the aim is clearer control, better awareness or a more usable outside area rather than gadget overload.

Heating control guides

Easier heating control and thermostat setup

Use these when the aim is easier heating control, a thermostat replacement, cleaner app setup or a handover that makes day-to-day use simpler.

What these guides cover
  • App setup The app side should be connected, usable and clear before the job feels finished.
  • Backplate tidy up A smart thermostat install should look finished on the wall, not leave the old thermostat position looking half-finished.
  • Schedules Basic schedule setup helps the system feel useful straight away instead of being left half-finished.
  • Stat and receiver On many smart thermostat jobs, the thermostat and receiver need to suit the existing controls and pair properly.
  • User handover Plain-English handover matters just as much as the wiring if the controls are going to be used confidently.
Common reasons to open a heating guide
  • Avoid guesswork Heating controls are much easier to live with when the setup is explained clearly instead of guessed at.
  • Better control Sometimes the aim is simply making heating easier to manage day to day.
  • Pairing issues If the thermostat keeps dropping offline, loses the receiver or refuses to stay connected in the app, the first job is to work out whether the fault sits in the local controls, the hub or Wi-Fi side, or a setup that was never finished cleanly.
  • Replace old stat A dated wired thermostat is a common reason to move to a cleaner smart-heating setup.
  • Setup unfinished Sometimes the hardware is there but the install or app setup was never properly completed.
How smart-heating visits usually work
  • App handover The last step is making sure the app feels clear to use: access, schedule basics, quick changes and a simple fallback.
  • Install and pair Install, pair and confirm the device fit rather than leaving wiring and app setup as separate unfinished tasks.
  • System check Before a smart thermostat is fitted, the first step is to check the current controls and the likely fit for the chosen model.

Entry and camera guides

Doorbells, cameras, entry systems and intercoms

Use these when the question is front-door awareness, shared access, tidy power, user handover, a broader access setup or a cleaner app setup.

What these guides cover
  • Panel, power and release Best when the panel, release setup or practical power side is the part that feels unclear.
  • App and sharing App setup, shared access and alert handover should feel clear for the household, not just technically online.
  • Coverage planning Plan the useful view first so the camera sees the door, path or entrance area that matters - not just the easiest place to mount it.
  • Mounting and power The neatest result depends on the fixing point, cable path and whether suitable power already exists nearby.
  • Wi-Fi checks Smart cameras are only as good as the connection quality in the location they are actually mounted.
  • Wired doorbells Doorbell installs often depend on the transformer, chime arrangement and app expectations being checked first.
  • Handset and monitor replacement Best when the user-facing intercom point needs a tidy replacement or a clearer everyday setup.
Common reasons to open an entry or camera guide
  • Gate and front-door access Best when the real question is how people actually get in, not just whether one point still rings.
  • Family access Shared access and notifications are often just as important as the hardware itself.
  • Fewer false alerts Too many alerts from passing cars, branches or evening light can make a camera less useful, not more reassuring.
  • Front door view A clean, dependable front-door view is one of the most common reasons to book a video doorbell or camera visit.
  • Poor current setup The kit may already be there, but poor mounting, weak power, messy setup or awkward alerts can make it frustrating day to day.
  • Supplied kit Customer-supplied equipment is often fine, but the fitting approach still needs checking properly.
  • Awkward current intercom setup Sometimes the intercom is already there, but the everyday setup is awkward, unreliable or clearly unfinished.
How doorbell and camera jobs usually work
  • Site photos and user needs A few clear entrance photos plus a note on who needs access usually make the first answer much clearer.
  • Handover and tuning The app, alerts and everyday use are tuned so the finished setup is genuinely practical.
  • Install and set up Mount, power and setup are handled together so the system works properly on the day.
  • Site photos A few photos of the entrance or mounting area usually answer most of the first questions quickly.
  • Call, release and handover A good intercom job finishes with clear call behaviour, release behaviour and a handover the resident can actually use.

Outdoor lighting guides

Outdoor lighting and sensor behaviour

Use these when the issue is failed outside lights, dark paths, awkward sensor behaviour or a practical lighting update around an entrance or path.

What these guides cover
  • Existing swaps Like-for-like updates on existing outdoor points are usually the cleanest way to handle small jobs.
  • Functional testing The finished point is checked properly, including the practical behaviour that matters day to day.
  • Light aiming Placement and aiming matter if you want useful light rather than glare or wasted spill.
  • PIR setup PIR just means the motion sensor on the fitting. Good setup is about useful coverage, sensible timing and fewer pointless triggers - not just making the light switch on.
  • Tidy cable runs Outdoor work should look deliberate and neat, not like an afterthought.
Common reasons to open an outdoor-lighting guide
  • Better coverage A practical improvement visit can be about getting the right light in the right place.
  • Dark paths Sometimes the job is simply making the approach, side path or garden path easier to use after dark.
  • Failed outside lights A dead outside light may be a failed fitting, a control issue or a wider outdoor fault.
  • False triggers If the outside light keeps coming on for passing traffic, moving branches or no obvious reason, the sensor setup needs checking.
  • Practical update A modest upgrade can make outside spaces easier to use without turning the job into a major project.
How outdoor-lighting jobs usually work
  • Confirm approach This is where the job is narrowed down into the simplest sensible approach: a same-point swap, light aiming or PIR setup, or a slightly broader practical update.
  • Install and set up Fit, aim and set up the point so the result is useful in real life, not just technically on.
  • Location photos A few clear photos of the entrance, path, gate or current fitting help confirm the likely outdoor lighting next step before visiting.

Testing, reports and managed next steps

EICRs, inspection findings and consumer-unit planning

Use these when the question has moved beyond a simple fitting or accessory and you need inspection, clearer report meaning or a managed replacement path.

EICR guides

EICRs and inspection reports

Use these when you need a report before upgrades, a tenancy or sale requirement, or a clearer explanation of inspection findings and next steps.

What these guides cover
  • Codes explained The point is not just receiving codes, but understanding what they mean for the property.
  • Fix priorities If remedials are needed, the report is translated into a practical order of action.
  • Inspection and report The EICR is arranged as a proper inspection and written report rather than as an informal check.
  • One point of contact Start with Willesden Smart Homes for the first check, scope and next-step explanation, rather than working out who to contact at each stage.
  • Pre-visit prep A little prep before an EICR helps the inspection run more smoothly and cuts down surprises on the day.
When an EICR is a sensible next step
  • Before upgrades An EICR can help when you want a better picture of the installation before bigger electrical decisions.
  • Compliant report If you need a formal report for records or decision-making, the registered pathway matters.
  • Plan remedials An EICR can turn a vague list of electrical concerns into a clear order of action.
  • Repeated faults If the same fault keeps coming back, the question is whether it needs local fault finding or a wider EICR.
  • Sale or tenancy A sale does not always need an EICR, but buyers, solicitors and landlords often need a clear report pathway and the right paperwork.
How the inspection usually works
  • Inspection booking and visit The inspection is booked and completed through the proper registered pathway.
  • Report and plan Once the report is back, the findings should turn into a clear order of action, not just a page of codes.
  • Request and scope Start with the property type, postcode and reason for the report so the right next step can be confirmed.

Consumer unit guides

Consumer units and managed replacement

Use these when the board has been flagged, trips keep returning, certification matters or a broader replacement plan is being considered.

What these guides cover
  • Clear handover A clear consumer unit handover means sensible labels, a plain-English walkthrough and a clear explanation of any paperwork.
  • Downtime plan Power-off time, access and practical prep are explained before the installation day.
  • Registered electrical delivery Consumer unit replacement is planned through the correct registered electrical delivery from the start.
  • Scope review Start by checking the existing board, the age of the installation and the reason replacement is being considered.
  • Testing and verification A new board is not just fitted and switched back on. Relevant checks are part of registered electrical delivery before handover and paperwork.
Common reasons people reach this stage
  • Board flagged If a survey, EICR or electrician has already flagged the board, a proper replacement plan may be the next step.
  • Need certification Where certification and compliance matter, registered electrical delivery keeps installation, testing and handover clear.
  • Outdated board Older boards with limited protection or dated equipment often trigger a replacement conversation.
  • Renovation planned Renovation often changes the electrical scope enough that the board needs reviewing before other work is priced or booked.
  • Repeated trips If protection keeps tripping and the wider setup is poor, replacement may be more sensible than piecemeal fixes.
How managed replacement usually works
  • Compliant plan Before installation is booked, registered delivery, likely scope, downtime and handover are clarified so the next step is clear.
  • Install and certify The agreed board replacement is installed, tested and certified through registered delivery, with the scope explained clearly first.
  • Scope and photos Show the board from a safe standing position and explain why replacement is being considered; do not remove its cover.
