House rewiring in Willesden, NW10

Whole-house and partial rewiring, with a written scope and agreed work stages.

Plan a whole-house or partial rewire with a written electrical scope.

Whole-house and partial rewiring • Written scope • Testing and handover

Decide what needs rewiring before choosing the fittings

A rewire starts with the wiring already in the home, the changes you are planning and the parts of the installation that can remain. The condition and arrangement of the circuits matter as well as the number of rooms.

Whole-house rewiring

Plan the electrical installation across the home as one project. The scope sets out the circuits to replace, socket and lighting positions, appliance supplies, controls and any consumer-unit work, with the installation and handover considered together.

It is useful to agree the room layouts and priorities before cable routes are covered and finishes are completed.

Partial rewiring

Replace an agreed part of the installation while retaining suitable existing wiring. The assessment needs to establish which circuits are affected, how the new work connects to what stays and whether that changes the wider scope.

A circuit can serve more than one room, so a room boundary does not necessarily define the electrical work.

Assessing the existing installation

Share any existing electrical report, known alterations and the proposed layout. Where a site assessment is needed, we agree its purpose, timing and any charge before the visit. The assessment informs what can stay, the circuit plan, cable access and whether the consumer unit needs attention .

Photos help with the first conversation but do not establish the condition of concealed wiring. You can send an existing EICR or inspection report if you have one.

Plan each room and the circuits that connect it

A useful plan shows how the home will be used: furniture positions, work areas, appliances, lighting and the controls you want to reach. Bring priorities as well as drawings, so essentials and optional additions can be distinguished in the quotation.

Power and appliance positions

Mark sockets, desk and TV positions, kitchen and utility appliances, and any equipment needing its own supply. Share product details when available so requirements can be checked against the proposed installation.

Lighting and switching

Consider everyday lighting, task lighting and separate zones, then decide where switches and dimmers should be reached. Agree fitting choices and compatibility before the finished positions are fixed.

Data and smart controls

Discuss data points, Wi-Fi equipment positions and useful control wiring while routes are accessible. Smart controls can be considered alongside ordinary switches, with compatibility and everyday manual operation part of the plan.

Explore lighting installation and controls or smart-home planning for more detail. These choices form part of the agreed scope; they are not automatically included in every rewire.

Agree the work stages around your refurbishment

The programme depends on the electrical scope, access and other work at the property. First and second fix are planned together so that decisions about the finished installation are made before walls and floors are closed.

  1. Confirm the design and access

    Agree the room and circuit plan, accessory choices, cable routes and any work on the consumer unit. Record access, opening-up, power interruptions and responsibilities in the quotation.

  2. First fix: prepare the wiring

    Install the agreed wiring and prepare accessory positions while the relevant routes are accessible. The sequence needs to fit the builder's work before plastering, fitted furniture or other finishes cover those areas.

  3. Second fix: fit the finished points

    Fit the agreed sockets, switches, lighting and controls when the rooms are ready. Confirm changes to products or positions before they affect the installation and quotation.

  4. Testing, certification and handover

    Electricians working for WSH carry out the electrical work, testing and certification. We confirm the electrical scope and any required specialist responsibilities before work starts, including the records to be provided and handover of the agreed controls.

If you will be living in the home

Tell us which rooms and essential services need to remain in use. Occupied-property arrangements are agreed in the quotation after the work and access have been considered.

  • Which rooms can be cleared and when floors or walls can be accessed
  • Furniture, possessions and shared access routes that affect the working areas
  • Necessary power interruptions and any equipment you depend on
  • The builder's programme and who is arranging the other trades

Do not assume every room or circuit will remain usable throughout the work. The quotation records the arrangements for occupation, access and coordination with your builder.

Opening-up and making good

Cable access can affect floors, walls and existing finishes. Responsibility for opening-up, making good, plastering and decoration is agreed in the quotation; those items are not automatically included in the electrical price.

A written quotation for the actual rewire

Whole-house and partial rewiring are quoted as projects. Small-job hourly rates do not price a house rewire, and a bedroom count alone does not describe the work.

What affects the quotation

  • The circuits being replaced and the condition of the retained installation
  • Socket, lighting and appliance quantities, positions and product choices
  • Cable routes, wall and floor access, and consumer-unit requirements
  • Occupied areas, work stages and coordination with other trades
  • Data, controls and any agreed provisions for later additions

What to agree in writing

  • The electrical work and materials included, with clear exclusions
  • Any assumptions about wiring, access or products still to be confirmed
  • Who supplies fittings and who handles opening-up and making good
  • The work stages, testing, certification and handover responsibilities
  • How changes or newly discovered work will be discussed and agreed

Read the project quotation guidance , then send the outline of your rewire. If a site assessment is needed, its purpose, timing and any charge are agreed before arranging it.

House rewiring questions

Do you offer both whole-house and partial rewiring?

Yes. WSH offers whole-house and partial rewiring. The existing installation and proposed changes are assessed to define which circuits are replaced, what can remain and how the work is set out in the quotation.

Can you tell whether my house needs a full rewire from photos?

Photos and an existing report can help with the first conversation, but they do not establish the condition of concealed wiring. Where a site assessment is needed, we agree its purpose, timing and any charge before arranging it.

Can we stay in the house while it is rewired?

Occupied-property arrangements are agreed in the quotation for your project. Tell us which rooms and essential services need to stay in use, along with access constraints. Do not assume every room or circuit can remain usable throughout the work.

Can you work alongside our builder?

Coordination with your builder and the electrical work stages are agreed in the quotation. Share the programme and contact arrangements so first fix, second fix and the responsibilities of other trades can be considered together.

Does a rewire quote include plastering and decoration?

Opening-up, making good, plastering and decoration are not automatically included in the electrical price. The quotation records the agreed inclusions, exclusions and who is responsible for each part.

Can lighting, data and smart controls be planned with the rewire?

Yes, these can be considered as part of the electrical brief while cable routes and room layouts are being planned. The agreed scope identifies the fittings, data points and controls included, with compatibility and everyday manual operation considered before products are chosen.

Who carries out testing and certification?

Electricians working for WSH carry out the electrical work, testing and certification. We confirm the electrical scope and any required specialist responsibilities before work starts, including the records to be provided at handover.

How much does house rewiring cost, and how long does it take?

The quotation and programme depend on the circuits, installation condition, point quantities, fittings, access, occupation and other work at the property. Whole-house and partial rewires use a written project quotation; small-job hourly rates do not price the rewire. Scope and work stages are agreed for the property before work starts.

Start with the home and the changes you have in mind

Discuss your rewiring project

Send your postcode, the areas you want to change and whether the home will be occupied. Plans, an existing report and safe photos are useful if available; you do not need a finished electrical design to enquire.

For a contained replacement or repair, use small electrical jobs . For a property outside Willesden/NW10, check the coverage guidance and share the address so we can confirm availability.
