Buying a new-build home in Redhill, Reigate or the surrounding Surrey area often means benefiting from modern insulation, efficient heating and a brand-new electrical installation. It may also mean your home should already be prepared for electric vehicle charging.
In England, Building Regulations Part S sets requirements for electric vehicle charging infrastructure in new residential properties. If your new home has an associated driveway, garage or allocated parking space, the developer will generally need to provide a compliant charge point or suitable infrastructure for one.
This guide explains what Redhill homeowners should expect, what to check before moving in and what to consider if you want to replace or upgrade the charger later.
What is Building Regulations Part S?
Approved Document S provides technical guidance for electric vehicle charging infrastructure in England.
Part S applies primarily to:
- New residential buildings
- New non-residential buildings
- Buildings converted into dwellings
- Certain major renovations
- Mixed-use developments
For new homes, the requirements usually apply where there is an associated parking space. This can include:
- A private driveway
- An integral or attached garage
- An allocated parking bay
- Certain communal or visitor parking spaces within the development
The rules are designed to ensure that EV charging can be provided without expensive and disruptive work after the development has been completed.
For most new houses with a private driveway or garage, the expectation is that the developer will install at least one EV charge point. In some developments, particularly those with shared or more complex parking arrangements, some spaces may instead be provided with cable routes and connection points for future installation.
Part S is the developer’s responsibility during construction. As a homeowner, you should not normally have to arrange initial compliance yourself. However, it is important to establish exactly what has been installed before you complete your purchase.
What does a Part S-compliant charge point look like?
A charge point installed to meet the requirements of Part S is more than an outdoor socket. It should be designed specifically for EV charging and installed as part of a suitable electrical circuit.
Typical requirements include:
- A minimum rated output of 7kW
- Smart functionality
- A suitable Mode 3 charging arrangement
- A Type 2 socket or suitable charging connection
- A charging status indicator
- Installation in accordance with relevant electrical safety standards
- Appropriate protection against earth and PEN conductor faults
A typical home charging point in Surrey will provide around 7.2kW from a single-phase domestic supply. The actual charging speed will also depend on the vehicle, battery capacity and the car’s onboard charger.
A basic 3.6kW unit may be suitable in some circumstances, but it would not normally meet the minimum Part S specification where a charge point is required for a new dwelling.
Tethered or untethered?
Part S generally favours an untethered Type 2 socket, allowing the vehicle owner to use their own compatible charging cable. This offers flexibility if you change vehicles in the future.
A tethered charger, with a permanently attached cable, can be convenient and may be appropriate in some situations. However, homeowners should check whether the particular installation was intended to satisfy Part S and whether the equipment matches the developer’s compliance documentation.
Smart charging requirements
The Electric Vehicles (Smart Charge Points) Regulations 2021 apply to private charge points sold for domestic or workplace use in Great Britain.
Smart functionality helps manage demand on the electricity network. It can allow a charge point to delay or adjust charging, for example when electricity demand is lower or when the owner has selected an off-peak schedule.
A compliant smart charger will generally include features such as:
- Pre-set off-peak charging hours
- The ability to schedule charging
- A randomised delay to prevent multiple chargers starting at exactly the same time
- Electricity usage measurement
- Continued charging functionality if the communications network goes down
- Security and data protection features
- The ability to respond to demand-side signals
This does not mean that you must always charge your car overnight or use a particular electricity supplier. It means the charge point should provide the functionality needed to manage charging intelligently.
Before moving into a new home, ask the developer for the charger manufacturer, model number and user instructions. You can then check the charger’s features, app requirements, warranty and compatibility with your vehicle.
What infrastructure might already be installed?
New homes around Redhill, Reigate, Merstham, Salfords, Earlswood and Nutfield commonly have modern consumer units and electrical installations designed around current construction standards.
Depending on the development, you may find:
- A dedicated EV circuit already connected to the consumer unit
- An installed 7kW wall-mounted charger
- Ducting or conduit running from the consumer unit towards the parking space
- A labelled spare way or provision within the consumer unit
- Load management equipment
- A future connection point near a communal parking bay
Some homes may appear to be “EV ready” because a conduit has been installed, but this does not necessarily mean that a charger can be connected immediately. A future cable route should be safe, unobstructed and suitable for pulling in the required cabling later.
It is also important to distinguish between:
- A live charge point, which is ready to charge a vehicle; and
- Passive infrastructure, such as ducting or a cable route, which makes a future installation easier.
If the developer has installed only the infrastructure, you may still need an electrician to install the charge point, protection devices and final connections.
What should you check before moving in?
Before completion or shortly after receiving the keys, ask the developer or site electrician for the following information:
1. Is a charge point installed?
Check whether there is a visible wall-mounted unit, pedestal or other charge point at the associated parking space. If there is no charger, ask whether the property has a cable route instead and where it terminates.
2. What is the charger’s rating?
Confirm that the unit is rated at least 7kW if it was installed to meet Part S. The charger should have a model number and manufacturer’s information.
3. Is it smart-enabled?
Ask for details of the app, Wi-Fi or mobile connectivity requirements, scheduling functions and any account you need to create.
4. Where is the dedicated circuit?
The EV supply should generally be on a dedicated circuit from the consumer unit. Ask for the circuit identification and whether load balancing has been installed.
5. What protection has been provided?
Domestic EV installations require suitable overcurrent protection, RCD protection and measures for the particular earthing arrangement. For many UK homes, the installer must also consider protection against an open-PEN fault on a PME or TN-C-S supply.
This may be provided through integrated PEN fault detection in the charger or through another compliant design, such as a suitable TT earthing arrangement. The correct solution depends on the property and equipment, so it should be confirmed by a qualified electrician rather than assumed.
6. Have you received the paperwork?
Request the electrical installation certificate, commissioning information, operating instructions and warranty details. Where applicable, you should also receive evidence that the work has been notified under Part P.
What if you want a different charger later?
You are not necessarily tied to the brand or model installed by the developer.
You may want a different charger because:
- Your new vehicle has different charging requirements
- You prefer a tethered or untethered design
- You want solar integration
- The original charger has limited app functionality
- You need better load management
- You want the charger positioned more conveniently
A replacement is not simply a case of disconnecting one box and connecting another. The electrician should check the existing circuit, cable size, protective devices, earthing arrangement, charger compatibility and manufacturer’s installation requirements.
If the original installation is sound, it may be possible to reuse some of the cabling and protection. If the new charger has different requirements, modifications may be needed. Any new circuit or alteration must be completed and certified appropriately.
Benefits and possible challenges for new-build owners
A Part S installation can provide several benefits:
- Less disruption than retrofitting a charger later
- No need to route cables through finished rooms or landscaping
- A convenient home charging point from the day you move in
- Better preparation for future electric vehicle ownership
- Potential access to smart charging and off-peak tariffs
There can also be practical limitations. A standard new-build installation may not be positioned exactly where you would prefer. Wi-Fi signal strength can affect app-based features, and a 7kW charger may place a significant additional load on the home’s electrical supply.
If you have solar panels, a heat pump or other high-demand equipment, ask whether the charger includes dynamic load management. This can help reduce the risk of the property exceeding its available electrical capacity, although it does not replace proper electrical design.

FAQs
Does every new-build home in Surrey need an EV charger?
Part S applies in England, including Surrey, where a new residential building has an associated parking space. In most typical new houses with a driveway or garage, at least one charge point is required. Specific requirements can vary for communal parking, covered spaces and developments where connection costs affect the number of active charge points that can be installed.
Is a cable route the same as an EV charger?
No. A cable route is infrastructure that allows cabling to be installed in the future. It does not necessarily include the charger, protective devices or a live electrical connection.
Does a Part S charger have to be 7kW?
A charge point installed to meet the standard Part S provision for a new dwelling is generally required to have a minimum rated output of 7kW. Always check the model and the developer’s compliance information.
Do new-build EV chargers need to be smart?
Private charge points sold for use in Great Britain are covered by the Electric Vehicles (Smart Charge Points) Regulations. A new domestic charger should therefore provide the required smart functionality, including scheduling and demand management features.
Can I replace the developer’s charger?
Usually, yes, but the replacement must be assessed and installed correctly. An electrician should check the existing circuit, earthing, RCD and PEN fault protection before installing a different charger.
Conclusion
For Redhill homeowners moving into a new-build property, Part S should make EV ownership more straightforward by ensuring that suitable charging infrastructure is considered during construction.
However, “EV ready” can mean either a fully installed 7kW smart charge point or simply a future cable route. Check what your developer has provided, request the electrical and compliance paperwork, and do not assume that a standard outdoor socket is suitable for regular vehicle charging.
