About House Rewiring
Full and partial rewiring for older homes, renovations, extensions and properties where the existing wiring is unsuitable for the intended use. A rewire should be based on actual condition, design requirements and test findings. Age alone does not prove that every cable needs replacing, while heavy alterations or poor previous work can make a younger installation unsuitable.

Price guidance
Rewiring is survey-priced rather than sold from a single website figure because property size, occupancy, finishes, circuit design, accessory count, access and making-good requirements change the scope significantly. AVAG confirms a quotation after understanding the installation and proposed layout.
Planning and assessment
Testing is not an optional finishing touch. Polarity, continuity, insulation resistance and other measurements or functional checks are selected to suit the work and installation so that the result is verified rather than assumed. The relevant circuit protection has to suit the circuit and the work being carried out. RCD or RCBO protection, protective-device ratings and disconnection arrangements cannot be selected by appearance alone. Existing installations do not automatically have to be rebuilt simply because they were installed to an earlier standard. The important question is whether the relevant existing equipment and protective arrangements are safe and adequate for the current circumstances and any new work. Cable routes and conductor sizes need to match the design conditions. Concealed cables, thermal insulation, grouped circuits, long runs and the expected load can all influence what is suitable. Earthing and protective bonding are part of the safety picture. New or altered work may depend on existing arrangements being adequate, so an electrician cannot responsibly ignore them where they are relevant to the proposed work.
A typical house rewiring enquiry in London starts with the postcode, property type and a short description of what you need. Photographs can be useful for an initial discussion, but they do not replace inspection or testing where the condition of the installation matters. AVAG then confirms whether the next step should be a quotation visit, a diagnostic attendance or a defined piece of work. Before starting, the scope and likely price are agreed. During the work, anything materially different from what was expected is explained before additional work is undertaken. On completion, the installation or alteration is checked and a completed rewire requires inspection and testing and normally an electrical installation certificate. building regulations notification requirements are separate and depend on the work.

House rewiring: practical considerations
A professional house rewiring quotation should make the scope understandable. The customer should know whether inspection, testing, standard materials, certification and making-safe work are included, and which items are subject to further assessment. That is particularly important when existing wiring is concealed and its condition cannot be established from photographs.
Electrical work should be designed around current use and foreseeable demand. Kitchens, heating equipment, home offices, extensions, garden buildings and vehicle charging can materially change how a property uses electricity. Even when only one job is being carried out, considering future requirements can avoid unnecessary rework.
Standards change over time. An existing installation is not automatically dangerous because it was installed to an earlier edition, and a new-looking accessory is not proof that the circuit behind it is satisfactory. Inspection, testing and the circumstances of the proposed work are what allow a competent electrician to make a reasoned assessment.
Customers should keep electrical certificates and reports with the property records. They help future electricians understand alterations, provide evidence of work carried out and reduce uncertainty when the property is sold, let or renovated later.
Where a job uncovers an unexpected defect, the correct response is to explain the finding and agree the safe next step. Concealed damage, borrowed neutrals, poor previous alterations and inaccessible junctions are examples of conditions that may not be visible until testing or access begins.
