Signs Your Andover Home Needs Rewiring

Published September 2026 | Signs your home needs rewiring

If you've noticed flickering lights, sockets that feel warm to the touch, or a fuse box that keeps tripping for no obvious reason, it's natural to feel unsettled - especially if this is the first time you've had to deal with anything like it and you're not sure whether it's urgent or something that can wait. The uncertainty about what to do next is often the hardest part, and it's easy to either panic unnecessarily or put it off when you really shouldn't. This guide walks you through everything clearly: what the signs mean, what you can check yourself, how to find a reliable electrician in Andover, and exactly what to expect from start to finish.

What Is Actually Happening - The Basics Explained Simply

Electrical wiring does not last forever. A properly installed modern system can perform well for several decades, but many homes in the UK - particularly those built before the 1980s - still have wiring that was put in under very different standards, using materials that are now considered outdated and in some cases unsafe. The cables running through your walls, ceilings, and under your floors carry electrical current from your consumer unit (the box where your circuit breakers or fuses are) to every socket, switch, and light fitting in your home. Over time, the insulation around those cables becomes brittle, connections loosen, and the system as a whole begins to struggle with the demands of modern appliances - things like EV chargers, heat pump systems, dishwashers, and multiple devices running at once.

In Andover, as in much of Hampshire, there is a large stock of pre-1970s housing. Victorian and Edwardian terraces, interwar semis, and post-war estates built in the 1950s and 60s are common throughout the area, and many of these properties still have their original wiring - or wiring that was last updated 40 or 50 years ago. The clearest signs of a very old installation are rubber-insulated cables (which degrade and crack over time, exposing live conductors), round two-pin sockets, and consumer units with rewirable fuses rather than the modern circuit breakers you'd expect to see today.

A rewire means replacing all of this: the cables, the sockets, the switches, and in most cases the consumer unit itself. The aim is to bring the entire installation up to current BS 7671 wiring regulations, giving your home a system that is safe, compliant, and capable of handling the electrical demands of 21st-century living.

Is This an Emergency or Can It Wait?

One of the first questions our engineers hear from homeowners is whether they need to act today or whether they have time to do some research and book something in for next week. The answer depends entirely on what you're seeing and where.

Some signs mean you should stop using affected circuits immediately and call an electrician the same day:

• A burning smell coming from a socket, switch, or consumer unit
• Scorch marks or blackening around any electrical fitting
• Sparks when plugging something in or switching it on
• A socket or switch that feels warm or hot to the touch
• Lights flickering across multiple rooms simultaneously
• The same circuit breaker tripping repeatedly in a short space of time

If you notice a burning smell in particular, switch off the relevant circuit at your consumer unit immediately - and if you can't identify which circuit it is, switch off the main switch entirely until you've spoken to a professional. These are signs of active faults that carry a real risk of fire.

Other signs are serious but not immediately dangerous, and can be assessed at a scheduled appointment within a few days rather than hours:

• Occasional flickering in one room only
• A consumer unit with no RCD (residual current device) protection
• Sockets that are cracked or discoloured but not warm
• A home with no Electrical Installation Condition Report (EICR) in over 10 years
• Wiring you know is more than 30 years old
• Round two-pin sockets, which indicate wiring installed before 1947

These should still be treated as a genuine priority - not something to defer indefinitely - but you have time to research your options, get multiple quotes, and make a considered decision without panicking.

What You Can Safely Check Yourself (With Zero Experience)

You do not need any electrical knowledge to carry out a useful visual inspection of your home. What you're looking for is anything that looks, smells, or sounds wrong. Work through this checklist before you call anyone.

1. Look at every socket and switch. Check for cracks, yellowing, or brown and black discolouration around the edges or on the faceplate. Heat causes discolouration, and discolouration means there has been a fault at some point.
2. Count the sockets in each room. If you rely on multiple extension leads or multi-way adaptor plugs to run everyday appliances, it suggests the original installation wasn't designed for modern load levels. This is very common in older properties across Hampshire.
3. Look at your consumer unit. Open the cover carefully - this is safe to do - and look at what type it is. If you see a row of porcelain or wooden-capped rewirable fuses instead of plastic circuit breakers, the system is likely several decades old. If there are no RCD switches (usually identifiable by a small "test" button), your installation lacks a critical layer of protection that has been standard practice since the 1990s.
4. Look for round two-pin sockets. These indicate wiring that almost certainly predates 1947. If you find any, a rewire is long overdue.
5. Listen when plugging things in. Any crackling, buzzing, or humming from a socket or switch when in use is worth noting and mentioning to an engineer.
6. Check for visible surface-run cables. If you can see cables running along skirting boards or attached to walls rather than concealed inside the structure, note whether they have a grey PVC sheath (modern) or a textile or rubber sheath (old and potentially degraded).

Write down everything you find before you call anyone - which rooms, which sockets or switches, exactly what you noticed. The more specific you can be, the more accurately an electrician can advise you and estimate how long an inspection will take. If you're unsure how to describe what you're seeing, the Voltrade GoFIX diagnostic tool can help you work through it step by step and identify what type of appointment you need before you book.

How to Find a Trustworthy Engineer in Andover

There are a few clear things to check that reliably separate properly qualified electricians from those you'd want to avoid. Knowing what to look for makes the process much less daunting.

The single most important credential is scheme membership. Electricians who carry out domestic electrical work in the UK should be registered with an approved competent persons scheme - most commonly NICEIC or NAPIT. Both schemes carry out regular technical assessments of their members. You can verify any electrician's current registration on the NICEIC or NAPIT websites by searching their name or company name, free of charge. Do this before you book anyone for significant work.

Ask specifically whether they will issue an Electrical Installation Certificate (EIC) on completion of any notifiable electrical work, which includes a full rewire or consumer unit replacement. This is a legal requirement in England and Wales. If an electrician suggests the certificate is optional or unnecessary, that is a serious warning sign and you should look elsewhere.

For initial assessments, ask whether the electrician can carry out an EICR (Electrical Installation Condition Report). This is a thorough inspection of your existing installation and the appropriate starting point before any rewiring decision is made. Most reputable electricians in Andover will recommend this as the first step - it gives everyone a clear, evidence-based picture of what is actually needed rather than assuming the worst based on the age of the property alone.

Get at least three written quotes before committing. Ask each one to clearly specify: what is included and what is excluded; whether making good (repairing walls, ceilings, or floors after cable runs) is included in the price; how many days the work will take; whether the consumer unit is included; and what brand of consumer unit they plan to install. These questions separate thorough quotes from vague ones very quickly.

Local word of mouth is valuable in a town the size of Andover. Ask neighbours, check local community groups, and read reviews on platforms that verify reviewers actually used the service. Look specifically for reviews mentioning rewiring projects rather than minor jobs - rewiring is a more involved process and you want evidence the engineer has done it before.

What a Repair Visit Looks Like (So You Know What to Expect)

If you've never had an electrician in for anything more complex than changing a light fitting, the prospect of a multi-day rewire can feel overwhelming. Knowing what happens at each stage removes most of that uncertainty.

The first visit is an assessment. The engineer will inspect your consumer unit, test a selection of circuits using specialist equipment, and carry out a visual check of sockets, switches, and any accessible cabling. This takes between one and three hours depending on the size of the property. If they carry out a full EICR, they'll test every circuit in detail and produce a written report grading any faults: C1 means immediate danger requiring urgent action, C2 means potentially dangerous and requiring action, C3 means an improvement is recommended but the issue is not immediately dangerous.

If a full rewire is required, the work is split across several days. For a typical three-bedroom semi or terraced property in Andover, most engineers estimate three to five working days for the electrical work itself. The process runs in two main phases:

1. First fix: Old cabling is removed, channels (called "chases") are cut into walls, and new cable is run throughout the property. Floorboards may need to be lifted in some areas. This is the most disruptive part of the job.
2. Second fix: Once any necessary plastering is complete and dry, the engineer fits all new sockets, switches, and light fittings, connects everything at the new consumer unit, and carries out full system testing.
3. Certification: The completed installation is tested against current standards and an Electrical Installation Certificate is issued. Scheme-registered electricians notify the local building control authority automatically as part of this process.

You can typically remain in the property during the work, though you'll need flexibility about which rooms are accessible day to day. Expect some periods without power to specific circuits and some dust and minor wall damage - both are normal and temporary. Discuss the day-by-day schedule with your engineer in advance, particularly if you work from home or have children at home during the day.

Typical Costs - So You Are Not Caught off Guard

Rewiring costs vary depending on property size, the complexity of the existing installation, and what the quote includes in terms of making good and materials. The following ranges reflect typical 2026 market rates for the Hampshire area.

• EICR (inspection and condition report): typically between 150 and 300 pounds for a standard domestic property
• Consumer unit replacement only: typically between 400 and 750 pounds, including testing and certification
• Partial rewire (one or two rooms): typically between 500 and 1,500 pounds
• Full rewire, two-bedroom property: typically between 2,500 and 4,500 pounds
• Full rewire, three-bedroom property: typically between 3,500 and 6,500 pounds
• Full rewire, four-bedroom property: typically between 5,000 and 9,000 pounds

These figures typically cover all new cabling, sockets, switches, a new consumer unit, testing, and certification. Making good - filling and skimming the channels cut into walls - varies considerably between contractors. Some include basic making good; others charge separately or expect you to arrange a plasterer independently. Always confirm this in writing before any work begins, and factor in a decorator if significant walls are involved.

Always check whether VAT is included. Most electricians quote inclusive of VAT for domestic work, but some sole traders quote exclusive, which adds 20 percent to the figure you've been given.

If you're a tenant in Andover, the responsibility for rewiring sits with your landlord, not you. Landlords of rental properties are legally required to carry out an EICR every five years and to act on any C1 or C2 faults identified. If your landlord is not meeting this obligation, you can contact your local council's private sector housing team.

Questions You Should Ask Your Engineer

A good electrician will answer these questions clearly and without hesitation. If they're evasive or dismissive, that tells you something important.

1. Are you registered with NICEIC or NAPIT? Can I verify this online?
2. Will you issue an Electrical Installation Certificate when the work is complete?
3. What exactly does your quote include - specifically, does it cover making good?
4. How long will the work take, and which areas of the house will be out of use each day?
5. Do you recommend an EICR before quoting for a full rewire?
6. Will the completed work be notified to building control automatically through your scheme?
7. What brand of consumer unit do you use, and does it come with a manufacturer guarantee?
8. Is there a workmanship guarantee, and if so, what does it cover and for how long?

Write the answers down. When you're comparing three different quotes, having each engineer's answers to these questions on paper makes the comparison far easier and protects you if anything is disputed later.

First-Timer Questions

How do I know if my home actually needs a full rewire or just some repairs?

An EICR carried out by a registered electrician is the definitive way to find out. This formal inspection tests every circuit in your home and produces a written report that categorises any faults clearly. Many properties that show obvious signs of age only need targeted repairs or a consumer unit replacement rather than a full rewire. The report gives you and your electrician an objective basis for the decision rather than guesswork based purely on how old the property looks or how long ago it was last updated.

Is it safe to stay at home during a rewire?

In most cases, yes. Electricians typically work through the property room by room, which means you can continue living in the parts that aren't actively being worked on at any given time. You'll need to expect periods without power to certain circuits and some mess from wall chases and cable runs. If you have young children or anyone in the household who would find the disruption difficult, discuss the schedule with your engineer before work starts so they can sequence things around the areas you use most.

How long does rewiring a typical Andover home take?

A standard three-bedroom property in Andover typically takes between three and five working days for the electrical work itself. Larger properties or those with particularly complex existing installations can take longer. This does not include any plastering or decorating that follows - if significant making good is needed, allow additional time for plasterwork to dry fully before second fix can be completed. Your electrician should give you a clear day-by-day schedule before starting so you know what to expect each morning.

Will rewiring make a mess of my walls and decoration?

Yes, to some degree, and it's worth being prepared for that. Running new cables involves cutting channels into plasterwork and sometimes lifting floorboards, and there's no way to avoid it entirely. Most electricians include basic making good in their quotes, but the quality of finish varies between contractors. If you have recently decorated, have specific wallpaper, or have finishes you're concerned about, raise this before any work begins. Budget for some redecorating after the rewire, particularly in rooms where a significant amount of cable was run through the walls.

Does rewiring add value to my property?

A rewire doesn't typically add direct value in the way a new kitchen or loft conversion might, but it removes a significant barrier to selling and re-mortgaging. Buyers and their solicitors increasingly request an up-to-date EICR during conveyancing, and a property with outdated or poorly maintained wiring can lead to price reductions or sales falling through entirely. In Andover's current property market, having a recently rewired home with a clean EICR certificate is a meaningful advantage that makes the sale process considerably smoother for everyone involved.
