What this job involves and what it costs
Garden and outdoor electrical work—from extra weatherproof sockets to garden lighting, outbuilding supplies, electric gates and EV chargepoints—typically starts at about £55–£75 for a simple extra socket (larger jobs quoted after survey). Serving Canterbury and surrounding areas including nearby villages and suburbs. All work is fully tested, certified and covered by a fixed-price guarantee agreed before work begins.
When you need it
- A socket cover cracked after rain and you can see water pooling or dripping around it.
-
Usually means the socket isn’t weatherproof and water is getting into the wiring — a safety risk that needs fixing.
-
Your garden lights trip the fuse or switch off every evening when they turn on.
-
Usually means an earth fault or overload in the circuit that needs investigation.
-
Pond pump or pond lighting works intermittently, the cable looks chewed or the plug/fittings are rusty.
-
Usually means damaged wiring or corroded connections allowing moisture in — risk of failure or shock.
-
Your seasonal or decorative lights blow a fuse or trip breakers when you plug them in.
-
Usually means the string or adapter is overloaded, damaged, or drawing more current than the circuit can safely supply.
-
You’re planning to add lighting, a socket or an outbuilding supply but you don’t know where existing buried cables run.
-
Usually means there’s a risk of hitting unknown cables and the installation needs a proper survey and safe routing.
-
You’ve been using outdoor extension leads, indoor adapters or temporary cables as a permanent outdoor supply.
-
Usually means the setup isn’t designed for long-term outdoor use and could fail or create a shock/fire hazard.
-
You want to install an EV charger, gates or other fixed outdoor equipment and aren’t sure about earthing or safety switches.
- Usually means the new equipment will need a qualified installer to check earthing, RCD protection and whether the work must be notified to building control.

What is involved on the day
On the day, we’ll survey the proposed outdoor circuit, confirm cable routes and safely isolate the relevant supply before work begins. We’ll install suitable weather-resistant equipment and protective measures in line with BS 7671 requirements. Once complete, we’ll test the installation and provide the appropriate electrical certificate.
Survey and isolation
Before any garden or outdoor electrical work begins, we’ll survey the proposed route, check the existing supply and identify any buried services, drainage runs or suitable cable entry points. This site survey confirms practical access, cable containment requirements, ground conditions and whether the consumer unit has adequate capacity and protective devices for the proposed circuit.
We’ll explain where power must be isolated and agree any temporary loss of supply before proceeding. Our isolation procedures include identifying the correct circuit, safely disconnecting it, locking off where appropriate and proving dead with suitable test equipment. We’ll also assess existing wiring, particularly in older Canterbury properties where ageing cable types or previous alterations may affect safety. If we find issues requiring attention, we’ll discuss them clearly and provide a fixed written price before any additional work is authorised.
Installation
With the route and supply confirmed, we’ll install the outdoor circuit using suitably rated cable, protective devices and weatherproof accessories appropriate to the location and intended load. We’ll protect buried cable at suitable depth, mark its route where required, and use mechanical protection where ground conditions or access demand it. Surface wiring is fixed securely, kept clear of damage risks and terminated in enclosures with an appropriate IP rating.
We’ll fit RCD protection where required and make certain outdoor sockets, switches and isolators are suitable for external use. For low voltage lighting, we’ll position transformers or drivers in accessible, protected locations and route cables to minimise disturbance to planting and paving. Connections are made in properly enclosed waterproof junctions, with glands and seals matched to the cable type. We’ll reinstate paving, soil or finishes carefully after completing the installation.
Testing
After installation, we’ll test the outdoor circuit to confirm correct polarity, continuity, insulation resistance, earth fault loop impedance and RCD operation. These tests verify that protective devices disconnect within required limits and that exposed metalwork, armouring and earth connections are safely bonded where applicable.
On the day, we’ll isolate the circuit where necessary, use calibrated test instruments and check sockets, lighting points, junction boxes and weatherproof accessories. Continuity checks confirm conductors are complete and correctly connected; insulation testing helps identify damage, moisture ingress or faults before energisation. We’ll also operate RCD protection at the consumer unit and test button function. You should expect brief interruptions to the relevant supply while testing is undertaken. For gardens with older wiring, alterations or flood exposure, periodic testing can identify deterioration early and help keep the installation safe in service.
Certificate
Once the outdoor work has passed testing, we’ll issue the appropriate electrical certificate for the installation or alteration, recording the circuit details, test results, protective measures and any observations. For new circuits, consumer unit alterations or other notifiable work, this is normally an Electrical Installation Certificate; minor additions may receive a Minor Electrical Installation Works Certificate.
We’ll explain what the document covers, including earthing, RCD protection, cable routes and equipment ratings, so you can retain clear compliance documentation for future maintenance, insurance or property records. Where Building Regulations notification applies, we’ll complete the required process through our competent-person scheme. Keep the certificate safely with your consumer unit information. Certificate validity depends on the installation remaining undamaged, suitably maintained and unaltered; later changes, garden works or flood exposure may require inspection and retesting.
Options and what we recommend
For most Canterbury gardens, we recommend a properly designed outdoor circuit rather than extending an indoor socket supply: it gives suitable protection, clear isolation and capacity for lighting, sockets, a pond pump or a future EV chargepoint.
| Option | Best use |
|---|---|
| LED lighting | Paths, patios and planting |
| Weatherproof sockets | Tools and occasional equipment |
| Irrigation timers | Controlled watering systems |
We’ll assess cable routes, buried services, loading and the condition of your consumer unit before specifying equipment. Armoured cable is often appropriate for external runs, with sturdy accessories positioned away from likely impact and standing water. Separate switching lets you isolate garden equipment without affecting the home. For Victorian terraces or older estate properties, we’ll also check for ageing cable types and capacity constraints. This approach keeps the installation practical, expandable and safer in wet conditions.
Rules and certificates
Outdoor electrical work must comply with the Building Regulations, and some garden installations may be notifiable under Part P of those Regulations. Notifiable work typically includes installing a new circuit, replacing a consumer unit, or carrying out work in a bathroom or other special locations; we assess design, earthing, protective devices and cable routing before installation.
We are NICEIC‑approved and registered for Part P, which means for qualifying notifiable work we can self‑certify and notify Building Control on your behalf; this avoids you having to arrange a separate Building Control application in those cases. If notifiable work is carried out by an installer who is not registered, you will usually need to arrange and pay for Building Control to be notified and inspected — this is the normal process, not a penalty.
We issue appropriate documentation: an Electrical Installation Certificate (EIC) for new circuits, a Minor Electrical Installation Works Certificate for certain additions to existing circuits, and an Electrical Installation Condition Report (EICR) where a formal inspection/report is required. We also maintain contractor’s liability insurance (currently £5m) for professional indemnity and third‑party reassurance.
Older homes around Canterbury
Older homes around Canterbury need particular care when we add garden electrics. Before we extend any circuit outdoors in Canterbury, we will assess the existing installation in that specific property — including earthing arrangements, the presence and rating of protective devices, the physical condition of any legacy cables and the capacity of the consumer unit serving that dwelling.
You should not assume an existing socket circuit in a Canterbury home is appropriate for garden lighting, pumps or other external equipment; for each property we will specify suitable RCD protection and weather‑resistant accessories appropriate to the local installation and exposure conditions in Canterbury.
How long it takes and whether you lose power
How long garden electrical work takes in Canterbury depends on the circuit route, ground conditions and whether the existing consumer unit can safely accommodate the addition. We’ll assess cable routes, burial depth, RCD protection and earthing before confirming the programme. Straightforward Garden lighting or a weatherproof socket installation may be completed within a day, while longer runs, trenching, multiple circuits or consumer-unit alterations can take longer.
We normally isolate only the relevant circuit while connecting and testing, so you shouldn’t lose power throughout the property. However, work inside the consumer unit may require a short whole-house shutdown for safe isolation and verification. We’ll explain this beforehand and restore supplies only after testing confirms correct operation. Remote control lighting, timers and switching are commissioned after installation, with outdoor equipment selected and fitted to suitable IP ratings.
