What Does Rewiring a House Involve?

When rewiring a house, electricians must methodically access walls, floors, attics, and ceilings to install new:

• Electrical cabling
• Fuse boxes
• Light switches
• Power sockets
• Light fittings and pendant lights

Once the infrastructure is replaced, they thoroughly test and certify that the new system meets all legal requirements.

A full house rewire is carried out in two main stages:

1. New wiring, protective devices, circuits, and components are strategically installed throughout the entire property.
2. New faceplates, switches, socket outlets, and light fixtures are securely fixed to the renewed electrics.

Rewiring a house is an intrusive process as electricians must channel out brickwork and plaster to embed cables and back boxes. Professional electricians work flexibly around homeowners by scheduling work in phases rather than occupying the whole home simultaneously.

Why House Rewiring is Crucial for Safety

There are five compelling reasons to rewire a aging or damaged electrical system:

1. Reduce fire risk – Outdated, degraded, or overloaded electrics pose serious fire hazards. Replacing wiring eliminates points of failure before they turn catastrophic.
2. Boost property value – Modern, certified electrics reassure buyers and can increase house prices by thousands.
3. Gain peace of mind – Rigorous testing and certification proves the electrical system is completely safe for residents.
4. Customise electrical layouts – Additional sockets, switches, or fuse spurs can be added wherever needed around the property.
5. Enable smart tech – Smart lighting, heating, security, and home cinema relies on up-to-date wiring.

Ultimately, rewiring is an essential upgrade to keep homes and families safe now and for years to come. Prioritising electrical safety brings invaluable security and comfort.

How Often Should You Rewire a House in the UK?

There are no rigid timescales for rewiring houses in the UK set in regulations. As a general guide, homeowners should consider electrical upgrades if:

• The existing electrics are over 25 years old
• The internal wiring shows any signs of deterioration or damage
• Fuses frequently trip or electrics spark, crackle or buzz
• Lights dim or appliances lose power when other devices turn on

To legally comply with safety standards, landlords must test their rental properties every:

• 5 years if tenants are living in-situ
• 10 years for vacant rental properties

Carrying out periodic electrical testing and inspections highlights if remedial work or full rewiring is required to satisfy electrical safety regulations.

Contact a qualified electrician like DH Electrical if your North West property shows any concerning signs or exceeds wiring age thresholds. Catching electrical issues early vastly reduces the risk of dangerous faults developing.

When Does a House Need Complete Rewiring?

Warning signs to look out for which indicate rewiring is needed include:

• Severe visible damage to insulation or cabling
• Regular electrical faults or appliance failures
• Frequent tripping electrics or blown fuses
• Discoloured, warm, or buzzing switch plates/sockets
• Burning smells from outlets or appliances
• Flickering lights across multiple rooms

If you notice any of these hazards, you must contact a certified electrician immediately. Leaving damaged electrics in-situ risks catastrophic fires and lethal electric shocks.

Can You Rewire a House Yourself?

Given the complexity, attempting DIY electrical rewires can:

• Breach building regulations if work is not registered
• Invalidate home insurance if dangerous faults manifest
• Risk the lives of occupants through improper installation

By law, only government-approved electricians registered under Competent Person schemes can certify domestic rewires in the UK.

Without adequate qualifications, rewiring a property yourself risks:

• Failed safety inspections and costly remedial work
• Legal prosecutions for non-compliance
• Endangering your household if wiring is substandard

Rewiring requires vast technical knowledge and experience. Even qualified electricians should prove suitable rewiring credentials, including:

• Up-to-date training on the latest wiring regulations
• Membership in the NICEIC and Registered Competent Person schemes
• Strong references and examples of past complete rewires
• Guarantees that workmanship meets industry standards

DH Electrical Services offer homeowners in the North West:

• NICEIC-approved electricians
• Professional certifications upon completion
• 6 year workmanship guarantees
• Support with building control notifications
• Competitive pricing with reliable timescales
• Priority emergency callouts if faults ever occur

With so much at stake, rely on a trusted industry authority for your vital electrical rewiring project.

Who Can Legally Certify Rewiring Work?

UK electrical safety laws enforce stringent requirements on who can verify and certify rewiring work.

To legally sign-off rewires, electricians must:

• Hold industry-recognized qualifications confirming competency
• Remain accountable to an authorised governing body
• Follow the latest editions of the IET Wiring Regulations
• Test installations thoroughly before completion
• Issue certification to clients proving compliance

Upon completing a rewire, you should always receive an Electrical Installation Certificate from your electrician. This details the full scope of works, confirms safety testing results, and bears the electrician’s licence details as proof of credibility.

If possible, directly verify an electrician’s credentials with the issuing body, such as NICEIC or Registered Competent Person. This validation gives assurance they satisfy industry standards for electrical services.

Choosing a reputable firm like our electricians in Liverpool gives confidence that your rewiring adheres to UK legislation. Our Competent Person registered team keeps qualifications current through regular training and assessment.

How Long Does Rewiring a House Take?

Industry experts estimate that rewiring a typical 3-bedroom semi-detached house takes approximately three days on average.

The duration of rewiring projects depends on factors like:

• Overall property size
• The extent of rewiring needed
• Any extra connections being added
• Whether the building remains occupied

Larger houses, dated wiring requiring significant replacement, or complex smart home integration understandably extend project timelines.

Is It Possible to Live at Home During Rewiring?

While possible to inhabit your property during a rewire, residents should prepare for substantial upheaval:

• Significant dust and debris
• Limited access to rooms
• Disruption from noisy installation work
• Redecorating once engineers finish

If circumstances allow, temporarily vacating your home until the rewiring completes avoids daily disturbances.

However, operatives take meticulous care to contain mess through dust sheets and floor coverings. They also work in phases, room-by-room to maintain household function.
