If you are considering an electric vehicle, one of the first practical questions is: how long does EV charger installation take?
For most Redhill and Surrey homes, a straightforward domestic installation takes approximately three to four hours on site. However, the complete process can take longer if your property needs an upgraded consumer unit, additional earthing or bonding work, a long cable route, or changes to the electricity supply.
The good news is that careful planning makes the process predictable. This guide explains what is involved in EV charger installation in Surrey, from the initial survey through to testing and certification.
At a glance: typical EV charger installation times
| Stage | Typical timescale |
|---|---|
| Initial enquiry and information gathering | Same day to a few days |
| Remote or on-site survey | Approximately 30–90 minutes |
| Quote and installation planning | Often within 24 hours |
| Standard installation visit | Around 3–4 hours |
| More complex installation | Half a day to a full day |
| Supply upgrade or 3-phase work | Potentially several weeks, depending on other parties |
| Testing, certification and handover | Included at the end of the installation visit |
These are typical ranges rather than guarantees. Every property is different, particularly in established parts of Redhill, Reigate, Merstham, Nutfield and surrounding Surrey areas.
Why Surrey homes can have different installation requirements
Many Surrey properties have private driveways, garages or side access, which can make charger positioning relatively straightforward. Others have detached garages, parking areas at the front of the property, shared driveways or limited off-street parking. These differences affect the length and complexity of the cable route.
The age and layout of the home also matter. Some older houses in and around Redhill may still have:
- An older fuse board with limited space for new circuits
- Outdated protective devices
- Long distances between the consumer unit and driveway
- External walls that require careful drilling and sealing
- Restricted access behind plasterboard, cabinets or fitted furniture
- Main bonding that needs upgrading before the charger can be energised
A qualified electrician must assess these issues before installation. An EV charger is a high-load electrical appliance, so it should have a properly designed and protected dedicated circuit rather than simply being connected to an existing socket circuit.
Step 1: Initial enquiry and pre-installation survey
The process usually begins when you provide details about your home, vehicle, charger preference and parking arrangement. Photographs can often help an electrician make an initial assessment, although some properties require a physical site survey.
The survey normally considers:
- The location of the main consumer unit
- The condition and available space in the consumer unit
- The incoming electricity supply and whether it is single-phase or 3-phase
- The proposed charger position
- The likely cable route
- The distance between the charger and the consumer unit
- Wall construction and access requirements
- Main earthing and bonding
- Whether load management or other protective measures may be required
A remote assessment may take only 15 to 30 minutes, while an on-site survey may take between 30 and 90 minutes depending on the property.
This is also the ideal time to discuss practical details such as whether the charger should be positioned near the front or rear of the driveway, how visible the cable will be, and whether conduit or trunking is appropriate.
Step 2: Quote and installation planning
Once the survey information is available, the electrician can prepare a clear quotation. This should identify the planned charger location, cable route, protective equipment and any additional work that may be necessary.
ADS Electrical aims to provide free quotes within 24 hours, wherever sufficient information is available. If the installation involves several trades or building work, we can also help coordinate the project so that the electrical work fits smoothly with the wider schedule.
For example, if a driveway is being resurfaced, it may be sensible to coordinate cable installation before the final surface is completed. Similarly, if a garage is being converted or rendered, cable routes can sometimes be concealed more neatly by planning the work alongside the other trades.
Step 3: Preparing the property
Before installation day, homeowners can help prevent delays by:
- Confirming the preferred charger location.
- Ensuring the driveway, garage and consumer unit are accessible.
- Moving stored items away from the proposed cable route.
- Making sure the home’s Wi-Fi reaches the charger location if app connectivity is required.
- Providing details of any planned building, driveway or renovation work.
- Checking that parking arrangements allow the vehicle to be positioned near the charger during testing.
If an older consumer unit is unsuitable or has no available space, the electrician may recommend an upgrade or a separate small consumer unit for the EV circuit. This can add time to the installation and may mean the work takes most of a day rather than just a few hours.
An upgrade is not automatically required in every older property. The decision depends on the condition, capacity and protective arrangements of the existing installation.
Step 4: What happens on installation day?
1. Confirming the final position
The electrician will normally walk through the installation with you before starting. They will confirm the charger position, cable route, access points and any visible conduit or trunking.
This final check is important because small changes to the charger location can have a significant effect on the cable length and installation method.
2. Safely isolating the electrical supply
Power will be isolated while work is carried out at the consumer unit. The electrician will take appropriate precautions before installing or modifying the dedicated circuit.
A short power interruption is normal. Your electrician should explain when the power needs to be switched off and how long this is expected to last.
3. Installing the dedicated circuit
The charger will usually be supplied by a dedicated circuit from the consumer unit. Suitable protective devices, such as an RCBO or other equipment specified for the installation, are selected according to the charger, property and applicable wiring requirements.
Work at a modern consumer unit with a spare way may take around 30 to 40 minutes. If the board is full, difficult to access or needs replacing, additional time will be required.
4. Running the cable
Cable installation is often the biggest variable in the schedule.
A short internal route from a nearby consumer unit to a garage wall may take less than an hour. A longer route around the outside of a house, through multiple walls or along a detached garage may take two hours or more.
The electrician will aim to keep the route neat, secure and protected. Depending on the property, the cable may be:
- Routed internally
- Installed externally in suitable conduit
- Run through a loft, garage or utility area
- Buried or protected where it crosses an appropriate external route
- Installed alongside existing building or landscaping work
Any holes should be drilled carefully and sealed appropriately to help protect the building from moisture and draughts.
5. Checking earthing and bonding
The electrician will check the earthing arrangement and main bonding, including bonding to relevant metallic services such as gas and water pipes.
If bonding is missing, undersized or inaccessible, remedial work may be required before the charger can be safely commissioned. This may add approximately 20 to 60 minutes, although the time depends on where the relevant services are located.
The installation may also require specific protective measures appropriate to the charger and the property’s earthing arrangement. These checks are an important part of a safe, compliant installation and should not be skipped to save time.
6. Mounting and connecting the charger
The charger is fixed securely to the wall or its mounting surface. The supply cable is then connected according to the manufacturer’s instructions, with cable entries, glands and terminations completed carefully.
The charger should be positioned at a practical height, protected from avoidable impact and located where the charging cable can reach the vehicle without creating an unnecessary trip hazard.
Step 5: Testing, commissioning and handover
After the physical installation is complete, the electrician carries out electrical and functional tests. These may include checks of:
- Cable continuity
- Insulation resistance
- Earth fault loop impedance
- Protective device operation
- RCD or equivalent protection
- Correct polarity and connections
- Charger operation and communication
- Load management equipment, where installed
The charger will normally be powered up and tested. Where possible, the electrician may carry out a test charge or demonstrate the unit’s operating sequence.
If the charger uses an app or Wi-Fi connection, the electrician can usually help with initial configuration. It is helpful to have your phone available and to know the Wi-Fi password.
The final handover should include an explanation of how to start and stop charging, understand the charger’s indicator lights and use any basic controls. You should also receive the relevant electrical certification and information about warranty and support. Where applicable, the installer can complete the appropriate notification process for the work.
What can speed up or delay an installation?
Factors that may speed things up
- A modern consumer unit with spare capacity
- A short, accessible cable route
- A charger positioned close to the main electrical intake
- Good access to the driveway, garage and consumer unit
- Clear agreement on the charger position before installation
- Strong Wi-Fi at the proposed charger location
- No remedial earthing or bonding work required
Factors that may cause delays
- An old or unsuitable fuse board
- A consumer unit with no available space
- Long external cable runs
- Difficult drilling through thick walls
- A detached garage or distant parking space
- Hidden obstructions or restricted access
- Inadequate main bonding
- The need for a DNO application
- A 3-phase supply upgrade
- Waiting for an energy supplier to alter or replace a smart meter
A smart meter is not automatically needed for every home EV charger installation. However, it may form part of a wider electricity supply or load-management arrangement. If a property needs a new 3-phase connection, the DNO and energy supplier’s timescales are separate from the electrician’s installation time and can extend the overall project by several weeks.
Common Redhill homeowner questions
Can a charger be installed in one day?
Often, yes. A standard installation can usually be completed in around three to four hours. More involved installations may take the majority of a day.
Does the charger have to be installed on the front of the house?
No. The best position depends on the parking location, cable route, wall construction and how the charger can be protected. Your electrician should discuss practical and visual considerations during the survey.
Will my old consumer unit need replacing?
Not necessarily. It will need to be inspected to confirm that it can safely accommodate the new circuit and protective equipment. If it is in poor condition, lacks capacity or does not provide suitable protection, an upgrade may be recommended.
Can installation take place while other work is being done?
Yes, and coordination can often make the project more efficient. If you are renovating a garage, replacing a driveway or carrying out other electrical work, tell your electrician at the planning stage.
