Installing an electric cooker in London isn’t simply a matter of connecting the appliance to electricity. The installation needs to be suitable for the cooker, safe to use and compliant with the applicable electrical and Building Regulations.
This guide answers the most common questions about electric cooker installation regulations, wiring, circuits, Part P, BS 7671, isolation switches, certificates and installation requirements in London.
Does an Electric Cooker Need to Be Installed by an Electrician?
For a fixed electrical connection, you should use a competent electrician.
The electrician can check whether your existing electrical circuit is suitable and safely connect the cooker according to the manufacturer’s instructions and applicable electrical requirements.
If new electrical work is required, additional Building Regulations requirements may apply.
What Regulations Apply to Electric Cooker Installation in London?
The main requirements to consider are:
- Part P of the Building Regulations
- BS 7671 Wiring Regulations
- Manufacturer’s installation instructions
- Appropriate electrical inspection and testing
Part P covers electrical safety in dwellings in England. BS 7671 provides the technical requirements used for electrical installations.
Does an Electric Cooker Need a Dedicated Circuit?
Many full-size electric cookers require a dedicated circuit, but not every cooker has the same electrical requirements.
The correct circuit depends on:
- Cooker power rating
- Manufacturer’s instructions
- Existing wiring
- Cable size
- Cable installation method
- Circuit length
- Protective device
- Overall installation conditions
Important
Don’t assume that every electric cooker requires a 32A circuit.
The electrician should calculate and assess the installation rather than applying the same breaker and cable size to every appliance.
Can I Connect a New Cooker to My Existing Cooker Circuit?
Possibly, yes.
If you’re replacing an existing electric cooker, the current circuit may already be suitable.
However, the electrician should check:
- Existing cable
- Circuit breaker
- Earthing
- RCD protection where applicable
- Cooker connection point
- Isolation arrangement
- New cooker’s power requirements
- Condition of the existing installation
If the circuit isn’t suitable, it may need to be upgraded or replaced.
Does an Electric Cooker Need a 13A Plug?
Not necessarily.
Some smaller ovens and cooking appliances are designed to operate from a 13A plug.
Many higher-powered electric cookers require a fixed electrical connection because their power demand is higher.
Always check the manufacturer’s installation instructions before deciding how the appliance should be connected.
Does an Electric Cooker Need a Cooker Switch?
A suitable means of isolation should be provided so the appliance can be safely disconnected from its electrical supply.
The appropriate isolation arrangement depends on the cooker and the installation.
Your electrician should determine the correct arrangement rather than relying on a generic installation rule.
What Is Part P?
Part P is the section of the Building Regulations concerned with electrical safety in dwellings in England.
It requires electrical installation work to be designed and installed so that it provides reasonable protection against danger.
Some electrical work is also notifiable.
For example, installing a new circuit for a cooker is generally notifiable work.
Is Replacing an Electric Cooker Notifiable?
Not necessarily.
There is an important difference between:
Replacing a cooker on an existing suitable circuit
and
Installing a completely new electrical circuit.
A straightforward replacement may not be notifiable in the same way as installing a new circuit.
However, any electrical work still needs to comply with the applicable safety requirements.
If you’re unsure, have a competent electrician assess the installation.
What Is BS 7671?
BS 7671 is the UK’s standard for electrical installations.
It covers areas such as:
- Protection against electric shock
- Earthing
- Cable selection
- Overcurrent protection
- RCD protection
- Isolation and switching
- Inspection
- Testing
Electric cooker installations should be designed and installed according to the applicable requirements of the current Wiring Regulations.
What Does an Electrician Check Before Installing a Cooker?
Before connecting your cooker, an electrician should consider:
- Cooker power rating
- Manufacturer’s instructions
- Existing cooker circuit
- Cable size and condition
- Circuit protection
- Earthing arrangements
- RCD protection where applicable
- Isolation
- Connection point
- Overall condition of the installation
This prevents a new cooker from being connected to an unsuitable electrical supply.
What If My Existing Wiring Is Too Old?
An old installation doesn’t automatically mean that the cooker cannot be installed.
The electrician should assess its actual condition and suitability.
They may recommend:
- Replacing damaged wiring
- Upgrading the cooker circuit
- Installing additional protection
- Replacing an unsuitable connection point
- Installing a new circuit
The correct solution depends on the condition and design of the existing installation.
Do I Need a New Circuit for an Electric Oven?
Not always.
It depends on the oven’s electrical load and the existing installation.
A lower-powered oven may have different requirements from a high-powered electric cooker.
The manufacturer’s instructions and electrical assessment should determine whether the existing circuit can be used.
What Happens If a New Cooker Circuit Is Required?
If your property doesn’t have a suitable circuit, the electrician may need to:
- Design the new circuit.
- Select appropriate cables and protective equipment.
- Install the circuit.
- Provide suitable isolation.
- Connect the cooker.
- Inspect and test the installation.
- Complete the appropriate certification.
- Complete Building Regulations notification where applicable.
A new cooker circuit is generally notifiable electrical work in England.
What Certificate Do I Get After Installation?
The certificate depends on the electrical work carried out.
Depending on the circumstances, you may receive an:
- Electrical Installation Certificate (EIC)
- Minor Electrical Installation Works Certificate (MEIWC)
Where applicable, Building Regulations compliance documentation may also be required.
Your electrician should explain which certification applies to the work performed.
Is RCD Protection Required for an Electric Cooker?
RCD requirements depend on the electrical installation and the applicable requirements of BS 7671.
The electrician should assess the circuit and determine the appropriate protection.
Don’t assume that every cooker installation requires exactly the same RCD arrangement.
Electric Cooker Installation in a London Flat
Installing an electric cooker in a flat can sometimes be more complicated than in a house.
Potential issues include:
- Older wiring
- Converted properties
- Limited access to the consumer unit
- Difficult cable routes
- Landlord requirements
- Freeholder requirements
- Managing-agent requirements
If you’re renting, check whether your landlord requires approval before electrical work is carried out.
Can a Landlord Install an Electric Cooker?
The cooker itself isn’t the main issue; the electrical installation supplying it must be safe and suitable.
Landlords should ensure electrical work is carried out by an appropriately competent person and that required inspection/testing and documentation are completed.
For rented properties, additional electrical safety obligations may apply.
What Should You Check Before Booking an Electric Cooker Installation?
Have these details available:
- Cooker make and model
- Cooker power rating
- Installation address
- Photos of the existing cooker connection
- Photos of the consumer unit if requested
- Whether you’re replacing an existing cooker
- Whether the property is a house or flat
This can help the electrician understand the job before arriving.
