PLANNED RESIDENTIAL ELECTRICAL WORK
Residential Electrical Services in London
Planned rewiring, consumer-unit upgrades, new circuits, sockets, lighting and electrical installations for London homes and residential renovation projects.
Planned residential projects only. Growchance does not provide emergency or 24-hour electrical callouts.
RESIDENTIAL ELECTRICAL WORK
Electrical work planned around your home.
Growchance undertakes planned electrical installations, alterations and upgrades for London homes. The electrical scope can form a standalone defined project or support a wider renovation.
The appropriate solution depends on the condition of the existing installation, the proposed layout, required circuits, product specifications and the work needed to access and reinstate finished surfaces.
A DEFINED PROJECT SCOPE
Installation, alteration and finishing must be considered together.
Cable routes, circuit requirements, access, testing, certification and making good are reviewed as connected parts of the proposed electrical work.
Rewiring and circuit work
Full or partial rewiring, new circuits and alterations to existing circuits can be assessed around the property’s condition and the proposed use of each room.
Consumer-unit upgrades
Consumer-unit work is considered alongside the existing installation, proposed circuit changes, testing requirements and any related access or finishing work.
Power and lighting
New or relocated sockets, switches, lighting points and fixed electrical supplies can be planned around furniture, appliances, room layouts and how the property will be used.
Renovation electrical work
Electrical work for kitchens, bathrooms and wider residential renovations can be coordinated with the building work, preparation, installation sequence and final finishes.
Growchance does not provide emergency or 24-hour electrical callouts, commercial electrical contracting, EICRs or standalone landlord electrical inspections. Send the proposed scope, property location and any available plans or photographs so the work can be reviewed properly.
FULL AND PARTIAL REWIRING
Match the rewiring scope to the property.
A complete rewire and a targeted circuit alteration are different projects. The correct scope should follow an assessment of the existing installation, the proposed layout and the electrical demand expected from the renovated home.
Rewiring also affects access and finishes. Routes through walls, ceilings and floors must be coordinated with the wider programme, especially where rooms are occupied or completed surfaces are being retained.
Full house rewiring
A full rewire may be appropriate where the installation requires comprehensive renewal or where a major renovation changes the property’s layout and electrical requirements throughout.
- Review of the proposed room layouts and electrical requirements
- Planning of circuits, socket positions and lighting points
- Cable routes coordinated with floors, walls and ceilings
- First-fix and second-fix work sequenced around other trades
- Testing and certification appropriate to the completed work
Partial rewiring and alterations
A partial rewire may suit a defined area or planned change where the retained installation can continue to support the proposed work, subject to proper assessment and testing.
- Electrical alterations for one room or a defined project area
- New circuits where the proposed installation requires them
- Relocation or addition of sockets, switches and lighting
- Integration with kitchen, bathroom or renovation work
- Clear separation between retained and newly installed work
Existing installation
Consider the visible condition, existing circuits and available information about previous electrical work.
Required layout
Confirm appliances, lighting, socket positions, fixed equipment and how each room will be used.
Routes and access
Plan cable routes and access alongside structural work, plumbing, plastering, flooring and decoration.
Test and finish
Complete the agreed installation, appropriate testing, certification and associated making good.
An older home does not automatically require a complete rewire, and newer finishes do not prove that the concealed installation is suitable. The proposed work and existing electrical installation must be considered before the final scope is agreed.
CONSUMER UNITS AND CIRCUITS
Electrical upgrades need a complete view of the installation.
Replacing a consumer unit or adding a new circuit is not simply a product swap. The existing installation, earthing arrangements, proposed electrical demand and the work connected to each circuit must be considered together.
Where an upgrade supports a renovation, Growchance can coordinate the electrical work with access, first-fix activities, plastering, joinery, kitchen or bathroom installation and the final decorative finish.
The final scope is confirmed after the relevant inspection and assessment by the appropriately qualified electrician.
Existing installation
The visible condition, available circuit information, earthing and the relationship between retained and proposed work are reviewed before the upgrade scope is agreed.
Proposed demand
New appliances, electric heating, lighting, power requirements and room-layout changes can affect the circuits and protective arrangements required.
New circuit requirements
New circuits may be required for particular equipment or areas. Their routes, access requirements and relationship with other work should be planned before finishes are completed.
Testing and certification
Appropriate inspection, testing and certification form part of the completed electrical scope. The documents required depend on the type of work undertaken.
SOCKETS, SWITCHES, LIGHTING AND POWER
Plan electrical positions before finishes begin.
Electrical layouts work best when they respond to the room, furniture, appliances and everyday use of the property—not simply the positions inherited from the previous layout.
Agreeing the main positions early helps coordinate cable routes, first-fix work, wall preparation, joinery and final decoration while reducing avoidable changes later in the programme.
Sockets and fixed power
Socket positions can be planned around furniture, home-working arrangements, televisions, fixed equipment and charging needs. Proposed additions must be considered alongside the existing circuit and the wider electrical scope.
Switch positions
Switches should support practical movement through the room, door openings and the intended lighting arrangement. Their location is best agreed before plastering and decoration.
General and task lighting
Ceiling lights, wall lights and focused task lighting can be planned around room use, cabinetry, mirrors, worktops and architectural features rather than treated as isolated fittings.
Appliances and specialist supplies
Fixed appliances and equipment may require dedicated supplies, isolation or manufacturer-specific arrangements. Product information should be available before the relevant installation work is agreed.
Small layout decisions can affect the complete installation.
Furniture, beds, desks, televisions and circulation routes.
Cabinet positions, worktops, appliances and concealed equipment.
General, task and feature lighting with the preferred controls.
Manufacturer information for appliances and fixed electrical items.
KITCHEN ELECTRICAL INSTALLATIONS
Coordinate the electrics with the kitchen design.
Kitchen electrical work should be planned from the final layout—not added after cabinetry, worktops and appliances have already been ordered.
Appliance information, cabinet drawings, lighting positions and ventilation requirements help establish the proposed supplies, controls, isolation and cable routes before first-fix work begins.

-
04
First-fix and installation sequence
Complete the required concealed work before plastering, decoration and kitchen installation, followed by the agreed second-fix work.
Late changes to appliances, cabinet dimensions or lighting can alter electrical positions and create avoidable work after surfaces have been prepared or finished.
BATHROOM ELECTRICAL INSTALLATIONS
Plan bathroom electrics around safety and layout.
Bathrooms require careful coordination between the electrical installation, water sources, ventilation, heating, lighting, waterproofing and the final room layout.
Product positions and specifications should be confirmed before concealed work begins so that the installation can be assessed and completed appropriately for the proposed location.
BATHROOM COORDINATION
Electrical positions cannot be separated from the bathroom design.
The bath, shower, basin, ventilation route, heating, mirrors, cabinetry and lighting arrangement all influence the electrical scope and suitable product positions.
Lighting
Ceiling, wall, mirror and task lighting should be selected and positioned with the bathroom layout and suitability for the proposed location in mind.
Ventilation
Extractor-fan selection, control, electrical supply and the ventilation route should be coordinated before ceilings and walls are closed or finished.
Heating and fixed products
Electric underfloor heating, towel rails, mirrors and other fixed electrical products require confirmed specifications and suitable supplies, controls and locations.
Testing and certification
The completed electrical work is inspected, tested and certified as appropriate to the installation by the relevant qualified electrician.
OUTDOOR LIGHTING AND POWER
Extend safe, practical power beyond the house.
Outdoor electrical work may support entrances, gardens, terraces, sheds, outbuildings or external equipment. The design must respond to the intended use, route, environment and existing installation.
Positions and cable routes should be planned alongside landscaping, drainage, paving, external finishes and future access so that the completed installation remains practical to use and maintain.
EXTERNAL INSTALLATION
Product suitability is only one part of the design.
The supply, circuit protection, cable route, connection points, controls and installation environment must also be considered by the appropriate electrician.
Entrance and security lighting
External lighting can be planned around entrances, paths, access points and the way the property is approached after dark.
Garden and terrace lighting
Lighting positions, controls and routes should be coordinated with planting, paving, boundaries and the intended use of each outdoor area.
External power
Outdoor sockets and fixed supplies can be considered for defined residential uses, subject to the existing installation and the requirements of the proposed equipment.
Sheds and outbuildings
Proposed lighting or power for an outbuilding requires assessment of the route, distance, intended demand, structure and suitable installation approach.
This service covers planned residential outdoor lighting and power within Growchance’s verified scope. Specialist EV charging, photovoltaic and battery-storage installations are not currently offered through this page.
DOMESTIC ALARM INSTALLATION
Plan detection around the property and its use.
Smoke, heat and carbon-monoxide alarms should form a coordinated system suited to the home’s layout, fuel-burning appliances, circulation routes and the wider project.
The required alarm types, locations, power arrangement and interconnection should be confirmed for the particular property rather than selected from a generic room count.
CONNECTED SAFETY PLANNING
Detection requirements can change when the layout changes.
Extensions, loft conversions, additional bathrooms, altered escape routes and HMO conversions can affect the wider fire-safety and detection strategy.
Smoke alarms
Smoke detection may be required across circulation areas and relevant rooms, with the final arrangement determined by the property and applicable project requirements.
Location and system type must be confirmedHeat alarms
Heat detection may be suitable in locations where normal cooking activity or environmental conditions could make smoke detection inappropriate.
Coordinate with kitchens and altered layoutsCarbon-monoxide alarms
Carbon-monoxide detection should be considered where relevant fuel-burning appliances and associated requirements apply to the property.
Confirm appliance and property requirementsHMO fire-safety, alarm and emergency-lighting requirements form part of a wider property, licensing and compliance strategy. Use the dedicated HMO service page for complete conversion and renovation enquiries.
ACCESS AND MAKING GOOD
Electrical work affects more than the visible fittings.
New wiring and altered circuits may require access through walls, ceilings, floors, joinery or existing service routes. The amount of disruption depends on the property, the installation method and which finishes are being retained.
Growchance can coordinate the electrical installation with the associated opening-up, protection, local repairs, plastering and agreed decorative making good.
Protect the property
Agree working routes and protect relevant floors, furniture and retained finishes before opening-up or installation work begins.
Create suitable access
Cable routes may require controlled access through plaster, boards, floors, ceilings or joinery according to the agreed installation approach.
Complete electrical work
First-fix and second-fix activities are sequenced around other trades, products, testing requirements and the wider renovation programme.
Make good and finish
Agreed local repairs, plastering and decoration can follow after the concealed work and necessary checks have been completed.
Complete concealed work before closing and finishing surfaces.
Chases, access openings and cable routes should be completed before final plastering and decoration.
Access below floor finishes must be considered before flooring is installed or retained finishes are disturbed.
Concealed supplies and outlet positions should follow confirmed drawings before units or fitted joinery are installed.
Required checks should be completed before relevant access points are permanently closed or concealed by finishes.
Local filling, plaster repairs and full decorative reinstatement are different scopes. The quotation should state which surfaces will be opened, what level of repair is included and whether final decoration forms part of the agreed work.
TESTING, CERTIFICATION AND PART P
Complete the electrical work with the right checks and documents.
Domestic electrical installation work must be designed and completed safely. The inspection, testing, certification and Building Regulations route depend on the type and extent of work undertaken.
Growchance coordinates relevant electrical work through the appropriately qualified electrician. The required documents should be identified as part of the agreed project scope.
PROJECT COMPLETION
Certification should reflect the work actually completed.
A minor alteration, a new circuit, a consumer-unit change and a full rewire do not necessarily follow the same documentation or notification route.
Inspection
Relevant parts of the installation are inspected during and after the work so that concealed items and completed connections can be considered appropriately.
Testing
The completed electrical work is tested as appropriate to verify the installation covered by the agreed project scope.
Certification
The certificate provided depends on the electrical work completed. The relevant electrician confirms the appropriate documentation for that installation.
Building Regulations
Where electrical work is notifiable, the compliance route should be established before work begins and completed through the appropriate competent-person or Building Control process.
Approved Document P provides statutory guidance for electrical safety in dwellings. Electrical Safety First also explains the homeowner’s responsibilities and the role of registered electricians.

ASSESSMENT AND DELIVERY
A defined process from the first enquiry to handover.
Electrical work should be planned around the property, the intended use of each space and any connected renovation work. We establish the practical scope before installation begins and coordinate the programme with the appropriate qualified electrician.
Initial enquiry
Tell us about the property, the electrical work required and whether it forms part of a kitchen, bathroom or wider renovation programme.
Information review
We review the available drawings, photographs, existing installation details and access information before deciding whether a site visit is required.
Electrical scope
The proposed circuits, outlets, lighting positions, equipment and certification requirements are considered with the appropriate qualified electrician.
Written quotation
The quotation identifies the agreed work, principal inclusions, exclusions and any assumptions that could affect the final programme or price.
Coordinated installation
First-fix and second-fix work is programmed around access, other trades, decorating and the wider renovation sequence where these activities are connected.
Testing and handover
Relevant completed work is tested, the appropriate documentation is provided, and any agreed making good is completed as part of the defined project scope.
QUOTATION AND PROGRAMME
What affects the scope, price and timescale?
Electrical projects are priced against the work actually required — not from one standard rate. The existing installation, access, specification and relationship with other trades all influence the quotation and programme.
Existing installation
The age and condition of the consumer unit, circuits, cabling and previous alterations can affect the work needed to complete a safe, compliant installation.
Project extent
A complete rewire, new circuit or coordinated renovation package requires a different programme from adding a limited number of sockets, switches or lighting points.
Access and cable routes
Floor construction, ceiling access, wall finishes, fitted joinery and occupied rooms influence how cables can be routed and how much protection or making good is required.
Fixtures and specification
The number and type of accessories, decorative fittings, lighting controls, appliances and specialist products affect installation time, testing and material costs.
Other trades
Kitchen fitting, bathroom work, plastering, decorating and structural alterations may determine when first-fix, inspection and second-fix electrical work can take place.
Testing and certification
The type of work, existing circuit condition and applicable notification or certification requirements are considered when the scope is prepared.
A clear scope supports a more reliable quotation.
Provide drawings, photographs, an electrical schedule or the proposed room layout where available. The quotation will identify the principal inclusions and assumptions. Detailed electrical cost guidance will remain on the separate Electrical Cost Guide rather than duplicating pricing across this service page.
