Socket replacement
Compatible accessories fitted after the existing box, wiring and earthing are assessed.
Alesta · Switch and socket installation in London
Electrical points positioned, connected and tested properly.
Replacement and new switch or socket work planned around the existing circuit, accessory specification, cable route, wall construction and applicable testing.
☎ Call 020 3608 3976Circuit before accessory
A new faceplate is only one part of the electrical work.
A like-for-like replacement, conversion to a different control and installation of an entirely new point involve different wiring, load and access questions. Decorative accessories can also require deeper boxes, neutral conductors, earthing or compatible dimming loads.
We request photographs of the accessory, wider wall and consumer unit before booking. Circuit condition, cable routes, wet zones and damaged wiring can change the scope, while plastering, decoration and smart-device configuration remain separate unless listed.
Switch and control work
Suitable standard or specialist controls matched to circuit and connected load.
New point planning
Cable route, circuit capacity, wall access and protection established before installation.
Inspection and testing
Completed work checked and tested to the applicable electrical scope.
Common reasons customers call
When electrical points are damaged, outdated or poorly positioned.
A socket or switch is cracked or loose
Visible damage needs isolation and assessment rather than continued use.
A room has too few usable sockets
A permanent point may be safer and more practical than repeated extension leads.
The finish no longer suits the room
Decorative replacement depends on box depth, earthing and accessory compatibility.
A renovation changes furniture or lighting
New positions need coordination before walls and final decoration are complete.
Why Alesta for switches and sockets
A tested installation rather than a cosmetic swap.
Existing wiring is checked
Damage, conductor length, earthing and box condition are not hidden behind a new plate.
Accessories are matched
Load, dimming, USB, smart and metal finishes receive relevant compatibility checks.
Routes are agreed
Openings, surface trunking or concealed routes are discussed before new points proceed.
The circuit is tested
Applicable checks confirm the completed work rather than relying on operation alone.
A safely isolated installation
How we install switches and sockets.
Planning starts with the intended outcome. We ask whether the task is a replacement, relocation or new point and request photographs of the existing accessory, wider wall and consumer unit. Customer-supplied products need model and specification details, especially dimmers, smart controls, USB outlets and metal faceplates. Wall construction, desired position, nearby water, furniture and likely cable route help determine whether the visit is straightforward or requires a survey.
At the property, the electrician confirms the circuit and safely isolates it before opening the accessory. Existing conductors, earthing, box depth, signs of heat and mechanical condition are inspected. A cracked faceplate may conceal loose or damaged wiring, while an attractive replacement may not fit the existing box. Where circuit condition or test results indicate a broader fault, the finding is explained before the work expands.
For compatible replacements, conductors are prepared and terminated to the accessory requirements without hiding damaged insulation or overcrowding the enclosure. New points require an agreed cable route and suitable circuit design, protection and fixing. Openings, floor access, chasing or surface containment are limited to the written scope. Smart switches may require a neutral, hub, wireless connection or customer account setup that must be confirmed separately.
Before energisation, the electrician inspects and tests the completed work as applicable, then checks the accessory and connected load in normal operation. Circuit information and certification are provided where required for the scope. Customers receive an explanation of controls, any excluded decoration and any legacy concern. The objective is a point that is electrically suitable and maintainable, not merely straight on the wall.
Clear pricing
Switch and socket installation prices.
Cost depends on replacement versus new point, accessory, circuit condition, cable route, wall construction, testing and making-good requirements.
| Service scope | Price | What affects the final price |
|---|---|---|
| Like-for-like accessory replacement | Quoted from photographs | Accessory, box, wiring condition, access and testing |
| Decorative, smart or specialist control | Quoted after compatibility review | Specification, load, neutral, box depth and configuration |
| New or relocated electrical point | Site-specific quotation | Circuit capacity, cable route, protection, openings and certification |
Pricing context: Photographs and accessory details are required for an honest quote. New circuits, fault remediation, plastering, decoration and smart-home configuration are separate unless expressly included.

Switch and socket FAQ
Before the electrician arrives.
Useful answers about replacements, new points, smart controls, metal plates, decoration and pricing.
☎ Call 020 3608 3976Can any switch or socket replace the existing one?
No. Box size, wiring, earthing, load and accessory specification must be compatible. Share the product details before purchase where possible.
Can you add a new socket anywhere?
A suitable circuit and cable route are required, and wet zones, wall construction and access can restrict position. A survey may be needed.
Do smart switches require special wiring?
Some require a neutral conductor, minimum load, hub or specific lamp compatibility. The exact model and existing wiring must be checked.
Are metal faceplates suitable for every installation?
They require appropriate earthing and compatible boxes and wiring. The electrician will confirm suitability before fitting.
Will the power be switched off?
Yes, the relevant circuit must be safely isolated for the work. Expected interruption is explained at the visit.
Is plastering and decorating included?
Only when stated. New or relocated points can require openings, chasing or surface routes, with making good agreed separately.
What affects the final price?
Accessory type, circuit condition, box depth, cable route, wall material, testing, access, certification and making good affect the quote.
