Practical installation services

Electrical Work Shaped Around Each Room and Each Load

Electrical installation is not a one-size-fits-all service. A bedside socket, an induction hob and a garden office all place different demands on the installation. We review the load, environment, route and protection before agreeing how the work should be completed.

01

Sockets, Switches & Power Points

Additional outlets and replacement accessories are positioned around furniture, equipment and everyday use.

02

Lighting & Controls

Ceiling lights, wall lights, LED systems, dimmers, sensors and outdoor lighting are installed to the agreed layout.

03

Dedicated Appliance Circuits

Cookers, hobs, showers, heating equipment and other fixed loads receive circuits designed for their requirements.

04

Extensions & Refurbishments

First fix and second fix are coordinated with builders, kitchen fitters, plasterers and decorators.

05

Outdoor & Outbuilding Power

Garden lighting, garages, workshops and offices are planned around cable routes, environmental conditions and isolation.

06

Commercial & Landlord Installations

Shops, offices, HMOs and managed properties are planned around access, operating hours and the building’s practical use.

The right approach for the project

From Small Additions to Full Electrical Fit-Outs

Some installations can be completed as a focused addition. Others need room-by-room design, new distribution and careful coordination with several trades. We define the scope early so you know what is being installed, what the existing system must support and where separate work may be needed.

HOME

Residential Additions

New sockets, lighting, appliance supplies and practical upgrades for occupied homes, landlords and rental properties.

BUILD

Renovations & Extensions

First-fix and second-fix installation coordinated with structural work, kitchens, bathrooms, lofts and wider refurbishment.

PRO

Commercial & Managed Sites

Electrical fit-outs and alterations planned around business use, shutdowns, access, equipment and ongoing maintenance.

If the existing distribution board cannot safely support the planned work, related consumer unit upgrades can be reviewed as part of the wider project.

Clear service boundaries

What Is Not Automatically Included in an Electrical Installation?

Your quotation lists the circuits, accessories, fittings and testing included in the agreed work. Building, specialist systems and decorative finishes remain separate unless they are clearly shown in the proposal.

  • Plastering, painting, wallpapering or full decorative making good
  • Premium or decorative light fittings unless listed in the specification
  • Data, CCTV, smart-home, fire-alarm or audio systems unless agreed
  • Meter, service head or network equipment owned by the supplier or DNO
  • Asbestos surveys, sampling, removal or specialist environmental work
  • Scaffolding, builders’ work or difficult-access equipment unless included
What to expect

A Clear Four-Stage Electrical Installation Process

We agree the layout and equipment before work starts, keep cable routes organised and coordinate the installation with the wider project. If site conditions affect the original plan, we explain the options before the scope changes.

  1. 01

    Survey & Design

    We review the property, electrical demand, outlet positions, access and the existing supply.

  2. 02

    First Fix & Cable Routes

    Cables, containment and back boxes are installed before surfaces and finishes are completed.

  3. 03

    Second Fix & Connections

    Sockets, switches, lighting controls, protective devices and agreed equipment are connected.

  4. 04

    Test, Certify & Handover

    The work is inspected, tested, labelled and handed over with the appropriate records.

Before work begins

How to Prepare for Electrical Installation Work

A few clear decisions before the appointment can prevent delays and avoid moving outlets later.

  • Confirm socket, switch, lighting and fixed-equipment positions
  • Provide appliance specifications and manufacturer requirements
  • Clear access to rooms, cupboards, lofts and proposed cable routes
  • Tell us about alarms, servers, medical equipment or essential supplies
  • Coordinate builders, kitchen fitters, plasterers and decorators around first fix
  • Share available plans, certificates and information about previous electrical work
Evidence behind the finished work

Inspection, Testing, Certification and Building Regulations Records

New electrical work must do more than switch on. The circuit needs to be inspected and tested, the protective measures must be verified and the results must be recorded. The certificate provided depends on whether the work introduces a new circuit or is a smaller addition or alteration.

EIC

Electrical Installation Certificate

Used for new installations, new circuits and work requiring full design, construction and test records.

MW

Minor Works Certificate

May be used for suitable additions or alterations that do not introduce a new circuit.

P

Part P Notification

Domestic work is notified where the installation falls within the notifiable categories in England.

MAP

Labels & Circuit Information

New circuits and protective devices are identified to support safe use and future maintenance.

When the existing installation needs attention

What Happens if the Existing Electrics Cannot Support the New Work?

A new circuit must connect to a suitable installation. If testing reveals poor earthing, damaged wiring, inadequate protection or insufficient capacity, we explain how it affects the proposed work and agree the safest next step before carrying out anything outside the quotation.

01

Identify the Issue

We establish which part of the existing installation affects the planned work.

SAFE

Keep the Work Safe

The new circuit is not energised where the required protective conditions are not met.

INFO

Explain the Impact

We show why the issue matters and which options are available.

CHECK

Recommend Further Assessment

Where the wider condition is unclear, a separate inspection may be the sensible next step.

£

Quote Separate Work

Repairs, upgrades or additional investigation are priced before they begin.

✓

Complete and Retest

Approved work is completed, tested and reflected in the final certification.

Where the existing cables are unsuitable across a wider area, electrical rewiring may be more reliable than continuing to add isolated repairs and extensions.

Clear pricing built around the actual scope

How Electrical Installation Prices Are Calculated

Electrical installation covers a wide range of work, so a realistic price needs more than a point count. Cable routes, circuit length, wall construction, access, equipment load, protective devices, finish specification and testing all shape the quotation. We price the agreed job rather than forcing every project into the same package.

Why Qualified Electrical Installation Matters

Why Electrical Installation Work Should Be Left to a Skilled, Qualified Electrician

Electrical work can look straightforward from the outside, but the safety of the finished installation depends on decisions hidden behind the walls. Cable size, circuit design, earthing, protective devices, connection quality and testing all need to work together. Benjamin Services approaches each installation carefully, so the result is safe to use, properly documented and built around the real demands of the property.

A circuit can appear to work and still be unsafe: undersized cables, loose terminals, reversed polarity, poor earthing, missing protection or an unsuitable cable route may remain hidden until someone receives an electric shock, equipment fails or heat develops into a fire.

Design, load and circuit protection The Installation Must Be Designed Before It Is Connected

A skilled electrician does not choose cable or protective devices by guesswork. We consider the connected load, cable length, installation method, environmental conditions, voltage drop, fault protection and how the circuit may be used in the future.

  • Correct cable sizing helps prevent overheating. A cable that is too small for the load or its installation method can become dangerously hot even when the equipment appears to work.
  • Suitable protective devices limit fault damage. MCBs, RCBOs, RCDs and other protection must match the circuit and disconnect safely when the required fault conditions occur.
  • Available capacity is checked before new demand is added. Where the existing board cannot support the planned installation, related consumer unit upgrades can be assessed before the circuit is connected.
Electric shock, burns and arcing Safe Isolation, Earthing and Connections Protect People

Electrical installation work exposes conductors, terminals and protective paths that must be handled correctly. Safe isolation, reliable earthing and secure connections are essential because one poor decision can leave accessible metalwork or equipment live.

  • Safe isolation reduces contact with live parts. The supply is identified, isolated, locked off where appropriate and proved dead before conductors are handled.
  • Earthing and bonding provide a controlled fault path. They help protective devices disconnect quickly instead of allowing dangerous touch voltage to remain on exposed metalwork.
  • Secure terminations help prevent heat and arcing. Loose, damaged or poorly prepared connections can create resistance, local overheating, burning and electrical fire.
Materials, routes and the surrounding environment The Right Equipment Must Be Installed in the Right Place

A dry bedroom, a bathroom, a garden office and a commercial kitchen do not present the same risks. A qualified electrician selects accessories, containment, cable routes and protection around moisture, heat, mechanical damage, accessibility and the way the space is used.

  • Suitable equipment helps prevent water ingress and failure. Outdoor and damp-location accessories need the correct construction, positioning and environmental protection.
  • Protected cable routes reduce accidental damage. Cables are positioned and supported to lower the risk from screws, nails, sharp edges, heat sources and normal building use.
  • The new work must be compatible with the existing wiring. If the surrounding circuits are damaged or unsuitable, electrical rewiring may be safer than adding new work to an unreliable installation.
Inspection, testing and certification Testing Finds Problems That a Visual Check Cannot See

The job is not complete because a light turns on or a socket powers an appliance. We inspect and test the finished work to verify continuity, insulation, polarity, earthing, fault protection and the operation of relevant protective devices before handover.

  • Testing can uncover hidden connection and polarity faults. These defects may not be visible during normal use but can make accessories, equipment or exposed metalwork unsafe.
  • Measured results confirm that protection can operate correctly. Test values help show whether the fault path and disconnection arrangements meet the requirements for the completed circuit.
  • The correct certificate creates a clear safety record. An EIC or Minor Works Certificate is issued as appropriate, while a separate EICR may be recommended where the wider installation needs assessment.

Electrical Installation Questions, Answered Clearly

Practical answers about new circuits, sockets, lighting, fixed equipment, Part P, testing, certification, disruption and electrical installation quotations across London.

New electrical work must suit the installation it connects to

Connected load, cable routes, earthing, protective devices, supply capacity and the condition of the existing system should all be reviewed before a new circuit or accessory is installed.

01 What is included in an electrical installation service?

Electrical installation can include new circuits, sockets, switches, lighting points, controls, fixed appliances, outdoor power and supplies for extensions or outbuildings. The exact scope depends on the property and the equipment being connected. We agree the layout, cable routes, protective devices, accessories, testing and certification before the work begins.

02 What types of electrical installation work do you carry out?

Benjamin Services installs additional sockets, indoor and outdoor lighting, cooker and hob circuits, shower supplies, heating controls, garden power, garage and outbuilding circuits, and electrical systems for renovations, extensions, shops and offices. We can complete focused additions or coordinate first fix and second fix as part of a wider building project.

03 Why should electrical installation work be completed by a qualified electrician?

A circuit may appear to work while still containing hidden safety problems. Cable size, connected load, earthing, polarity, protective devices and fault-disconnection times all need to be considered. A qualified electrician designs, installs and tests the work properly, helping reduce the risk of electric shock, overheating, arcing, fire, damaged equipment and unreliable tripping.

04 Can a new socket or appliance be connected to an existing circuit?

Sometimes, but the existing circuit must be suitable for the additional load and proposed connection. We review the circuit condition, protective device, cable capacity, earthing and test results before extending it. If a new circuit is required, the cable route, isolation and consumer-unit capacity are assessed as part of the design.

05 Do I need a new circuit for a cooker, shower or other high-load equipment?

Many higher-load appliances need a dedicated circuit, but the final design depends on the manufacturer's instructions, connected load, cable route and supply arrangement. Cookers, hobs, electric showers, heating equipment and similar fixed loads should not be connected by assumption. We calculate the requirements and select suitable cable and circuit protection for the installation.

06 Is electrical installation work notifiable under Part P in England?

Some domestic electrical work is notifiable under Part P, including new circuits, consumer-unit replacement and certain work in special locations. Other smaller additions may not require notification. The notification route is separate from the electrical certificate. We explain what applies to the agreed work and arrange the relevant process where required.

07 What is the difference between an EIC and a Minor Works Certificate?

An Electrical Installation Certificate is generally used for a new installation, a new circuit or work requiring full design, construction, inspection and testing records. A Minor Electrical Installation Works Certificate may be suitable for certain additions or alterations that do not introduce a new circuit. The certificate should match the work completed, not simply the size of the job.

08 Should I arrange an EICR before adding new electrical work?

An EICR can be useful when the condition of the wider installation is uncertain, especially in an older property or where previous alterations are poorly documented. It is not automatically required before every small installation, but new work must connect to a suitable electrical system. We may recommend further inspection where initial checks raise concerns.

09 What if the existing consumer unit cannot support the new installation?

We check available ways, protective devices, earthing, supply arrangements and the condition of the existing board. If it cannot safely support the proposed circuit, related consumer unit upgrades may be recommended. This is explained and quoted separately before the scope is expanded.

10 What if the existing wiring is damaged or unsuitable?

New electrical work should not be added to wiring that cannot be verified as safe and suitable. We identify the affected area and explain whether repair, further testing or electrical rewiring is the better option. Any additional work is agreed before it begins, and the completed installation is retested.

11 What do first fix and second fix mean?

First fix is the stage when cables, containment and back boxes are installed before walls, floors and ceilings are closed. Second fix takes place after the main finishes are ready and includes sockets, switches, lighting controls, protective devices and equipment connections. Coordinating both stages with builders, kitchen fitters, plasterers and decorators helps avoid delays and repeated work.

12 How disruptive is electrical installation work?

The level of disruption depends on the cable route, wall and floor construction, access and whether the installation is surface-mounted or concealed. Small additions may be completed with limited disturbance, while renovation work can require access beneath floors or inside walls. Plastering, decoration and making good are included only when they are clearly listed in the quotation.

13 How much does electrical installation cost in London?

The price depends on the number of points, circuit length, cable route, connected load, protective devices, access, fittings and the amount of testing required. A single socket addition and a new shower circuit are very different jobs. Benjamin Services provides a written quotation after reviewing the work, so the price reflects the actual installation rather than a misleading fixed package.

14 What information do you need to prepare an electrical installation quote?

Send the postcode, property type, a short description of the work and photographs of the proposed installation area. Include appliance specifications, preferred socket or lighting positions, floor plans where available and details of any renovation timetable. Mention restricted access, outdoor routes, essential equipment, commercial use or work that needs to be coordinated with other trades.
