When you need it
- Your lights flicker or dip when you switch the kettle or other appliances on.
-
This often means the circuit is overloaded or there’s a cage-green connection that needs checking.
-
Lamps keep failing or blowing more often than they should.
-
Frequent bulb failure can point to a poor connection, wrong fitting, or voltage issue.
-
Switches feel warm or hot to the touch.
-
A warm switch usually indicates a cage-green contact or overloaded circuit that should be inspected.
-
You smell a burning or acrid odour from a light fitting or switch.
-
Burning smells can signal overheating or a failing component—don’t ignore it.
-
You see discolouration or scorching around switches, sockets or fittings.
-
Discolouration is a sign of heat damage and potential electrical fault.
-
A light buzzes, hums or makes unusual noises.
-
Buzzing often suggests a faulty fitting, incompatible bulb or cage-green wiring.
-
Water has got into an outdoor light or bathroom fitting, or fittings look corroded.
-
Water ingress or corrosion can compromise safety and means the fitting needs replacing with a suitably rated one.
-
You’re redoing a kitchen, loft, extension or renovating an older/period home and want new lighting.
-
Changes to the space usually mean wiring and fitting positions need planning and possibly upgrading.
-
Existing fittings are damaged, hanging cage-green, or not secure.
-
Damaged or insecure fittings can be dangerous and generally need replacement and proper fixing.
-
You want brighter, safer, or more energy-efficient lighting throughout the room.
-
Upgrading can improve visibility, reduce running costs and bring fittings up to current standards.
-
Your bathroom or outdoor lights don’t seem suitable anymore (steam, splash, or exposed to weather).
- Incorrect or low-IP fittings in wet areas risk water damage and won’t meet safety requirements.
If you notice any of these, don’t wait—some indicate urgent issues. We’ll inspect the circuit and fittings, then advise and carry out safe, compliant replacements or upgrades.

What is involved on the day
On the day, we survey the work area with you, isolate the relevant circuit safely and confirm the agreed installation. We then fit your lighting, test the completed work and check that all protective measures operate correctly. Where certification is required, we’ll provide the appropriate electrical certificate once the installation is complete.
Survey and isolation
Surveying the room comes first: we’ll confirm the lighting layout, check the existing wiring and circuit capacity, identify any concealed services, and agree the fitting positions with you. This survey isolation stage lets us assess access, ceiling construction, cable routes and whether the existing circuit is suitable for the proposed lighting.
Before any electrical work begins, we’ll isolate the relevant circuit at the consumer unit, apply appropriate safety protocols and prove dead using approved test equipment. We’ll also check for shared circuits, stored energy and signs of older cable types, particularly in Tonbridge’s period and post-war homes. Where conditions differ from the agreed scope, we’ll explain the implications and obtain your approval before proceeding. Our NICEIC-approved, Part P registered electricians keep the area controlled and make electrical safety the priority throughout.
Installation
Once the circuit has been safely isolated and the layout confirmed, we’ll install the agreed lighting fittings, cable routes and switches in line with current electrical regulations. Our NICEIC-approved electricians protect floors and furnishings, use suitable containment where required, and keep work areas tidy throughout.
For indoor lighting, we’ll securely fit pendants, wall lights, downlights or LED upgrades, ensuring appropriate support, fire protection and bathroom-rated equipment where applicable. Outdoors, we’ll position weatherproof fittings and cable entries to suit the environment. We can also install Smart controls, including compatible switches, dimmers and sensors, where these have been specified.
In older Tonbridge properties, we’ll work carefully around existing fabric and identify unsuitable cable types before connecting new equipment. We’ll explain any necessary variation before proceeding, so your agreed fixed price remains clear.
Testing
We’ll test the completed lighting circuit before handover, confirming polarity, earthing, insulation resistance and protective-device operation where applicable. Our electricians use calibrated test equipment and follow the relevant requirements of BS 7671, checking that the new fittings, switches and connections operate safely as intended.
Circuit testing includes verifying continuity of protective conductors, correct switching arrangements and suitable disconnection times where an RCD protects the circuit. We’ll also check dimmers, sensors, timers and bathroom or outdoor lighting controls, where fitted, to make certain they work correctly without compromising safety.
If testing identifies an issue with an existing circuit, such as deteriorated cable or an unsuitable connection, we’ll explain the finding clearly and discuss the safe options before proceeding. We won’t leave newly installed lighting energised unless it has passed the necessary checks.
Certificate
After the lighting installation has passed testing, we’ll provide the appropriate electrical certificate or Minor Electrical Installation Works Certificate, confirming the work completed and the test results recorded. This compliance paperwork identifies the circuit, protective devices, inspection details and measurements relevant to your new lighting.
We’ll explain which certificate applies and leave you with the documentation for your records. Certificate verification helps demonstrate that the installation has been inspected, tested and completed in accordance with current electrical safety requirements.
Where notifiable work is involved, we’ll make certain the required Part P process is followed. Keep the certificate with property documents, particularly if you’re a landlord, planning alterations or arranging an EICR. Our NICEIC-approved electricians complete certification carefully, so you have clear evidence of safe, professionally completed work.
Options and what we recommend
For most Tonbridge homes, we recommend LED lighting designed around how each room is used, with dimmable fittings in living areas and practical task lighting in kitchens, bathrooms and workspaces. This approach improves comfort, visibility and energy efficiency without compromising LED aesthetics.
| Area | Recommended option | Why it works |
|---|---|---|
| Lounge | Dimmable warm LEDs | Flexible, relaxed atmosphere |
| Kitchen | Under-cabinet task lights | Clear preparation lighting |
For bathrooms, we’ll specify suitably protected fittings for the location and use bright, even illumination around mirrors. Outdoors, sensor-operated lighting can improve safe access at doors, paths and driveways while limiting unnecessary running time.
Smart controls suit households wanting scheduled lighting, scene settings or app control, but we’ll recommend straightforward switches where simplicity is preferred. We’ll discuss fitting positions, glare and maintenance access before providing your fixed written price.
Rules and certificates
Lighting work that involves a new circuit, work in a bathroom or other specified location may fall under Part P and could be notifiable; replacing a consumer unit is also a type of work that can require notification. As NICEIC-approved, Part P-registered electricians, we are able to self-certify qualifying notifiable work and notify Building Control on your behalf where appropriate, but whether notification is required depends on the specific work and circumstances and it is ultimately the duty holder’s responsibility to ensure compliance.
We follow the current wiring regulations and select suitable fittings, cable protection and bathroom zone measures to help keep the installation safe. You will be supplied with the relevant paperwork where applicable: an Electrical Installation Certificate (EIC) for new circuits, a Minor Electrical Installation Works Certificate for certain additions to an existing circuit, or an Electrical Installation Condition Report (EICR) where an inspection report is appropriate.
These certificates provide evidence that the work has been carried out and tested at the time of completion and can assist with future maintenance and consumer protection; they do not guarantee future compliance if alterations are made later. We will explain which regulations and certificates are likely to apply before starting and include any certification arrangements in your written fixed price.
Older homes around Tonbridge
We will explain any remedial work relevant to your Tonbridge property clearly, give you a fixed written price before starting, and make certain the finished installation is safe, practical and sympathetic to the specific character of your home in Tonbridge or East Peckham.
Around Tonbridge the housing we see most is Georgian and Victorian houses near the castle and river, inter-war semis, riverside properties in the Environment Agency flood warning area. That shapes the work we are called to: riverside flood-warning-area electrics, Georgian and Victorian period work near the castle, EV chargers for commuters. Every job is priced in writing before we start, and the same NICEIC standards apply whether the property is a period terrace or a new-build flat.
How long it takes and whether you lose power
Most straightforward lighting installations take a few hours, while several rooms, new circuits or extensive concealed cabling may take a full day or longer. We’ll provide a clear duration estimate after evaluating access, the existing wiring and the fittings you’ve chosen.
You may need a temporary outage while we safely isolate, test and connect the relevant circuit. For a simple replacement, this is often brief; work involving consumer unit connections, new cabling or fault investigation can require longer isolation. We plan interruptions carefully, confirm them before starting and keep essential disruption to a minimum. Our NICEIC-approved, Part P registered electricians test the installation on completion and issue the appropriate certification where required. If we uncover unsafe or unsuitable wiring, we’ll explain the options and agree any necessary work before proceeding.
