How Long Does a House Rewire Take?

If you are planning a house rewire, one of the first practical questions you will need answered is how long it is going to take. The duration affects everything — whether you stay in the property during the work, how you plan childcare or work-from-home arrangements, and how you sequence any decoration or renovation that follows. The honest answer is that it depends on your property, but there are reliable benchmarks that will help you plan with confidence.

This guide covers typical rewire timescales for different property sizes, the specific factors that affect duration in Cheshire’s older housing stock, and what to expect on a day-to-day basis during the work. For a full guide to rewire costs, see our house rewire cost guide for Cheshire .

How Long Does a House Rewire Take by Property Size?

For a standard property with modern cavity wall construction, accessible wiring routes and a straightforward layout, the following timescales are a reliable guide.

• 1-bedroom flat or studio: 2 to 3 days
• 2-bedroom house or flat: 3 to 5 days
• 3-bedroom house: 5 to 7 days
• 4-bedroom house: 7 to 10 days
• 5+ bedrooms or large property: 10 to 14 days or more

These are working days. A 3-bedroom rewire taking five to seven days means one to one and a half weeks of work on site. Period properties, solid-walled buildings, and properties with complex layouts will take longer — sometimes significantly so.

Why Period Properties in Cheshire Take Longer

Cheshire has an exceptional stock of period properties — Victorian and Edwardian terraces in Crewe, Macclesfield and Congleton, Georgian townhouses in Nantwich and Knutsford, and older cottages throughout the rural villages. If your property falls into this category, expect the rewire to take longer than the standard guide times, for two main reasons.

Access is harder. Modern properties with cavity walls and timber-framed partitions allow cables to be routed relatively quickly. Period properties with solid brick or stone walls require channels to be chased into the masonry — a slower process that demands more care to avoid unnecessary damage to original fabric. Lath and plaster ceilings cannot be drilled through carelessly. Solid concrete floors in older properties prevent under-floor cable routing entirely, requiring surface runs or significant additional chasing.

The existing wiring is in worse condition. In a period property that has not been rewired for decades, removing the old wiring safely takes longer than in a more recent installation. Cables that have degraded, connections that have corroded, and wiring routed through unexpected paths all add time to the strip-out phase before new wiring can be installed.

A 3-bedroom Victorian terrace in Crewe or Macclesfield that would take five to seven days in modern construction might take eight to twelve days. A Georgian townhouse in Nantwich with solid walls and lath and plaster throughout could take longer still. We always survey the property before quoting and provide a realistic programme as part of the fixed-price quotation.

What Happens Each Day During a Rewire?

Understanding the daily pattern of a rewire helps you plan your own arrangements around it.

Day 1 — Isolation and first fix begins. The supply is isolated, the existing consumer unit is removed and first fix wiring begins. First fix means routing all the new cables through the building — behind walls, under floors, through ceiling voids — before any sockets, switches or fittings are connected. Power will be off for most of the first day and may be partially restored in the evening depending on progress.

Middle days — First fix continues, room by room. The team works systematically through the property, routing cables for all circuits. Floors are lifted and replaced as each room is completed. Walls are chased where necessary. Partial power is typically restored each evening to key circuits such as the kitchen and at least one lighting circuit.

Final days — Second fix and testing. Second fix means fitting all the sockets, switches, light fittings and the new consumer unit, and connecting all the cables routed during first fix. The installation is then tested circuit by circuit — a requirement of BS 7671 that cannot be rushed. The Electrical Installation Certificate is issued on completion and the installation is live.

Will You Be Without Power During the Rewire?

The supply to the property is isolated during working hours but in most cases a temporary supply can be arranged to key circuits in the evening so you have lighting, refrigeration and phone charging overnight. Full power is restored on completion of the rewire.

The practicality of staying in the property during a rewire depends on its size and layout. For a 2-bedroom property taking three to five days, many homeowners stay put — it is inconvenient but manageable. For a larger property or one where all rooms are being worked in simultaneously, most homeowners find it easier to stay elsewhere for the duration. We discuss this at the survey stage and advise on what is realistic for your specific circumstances.

What Causes a Rewire to Take Longer Than Expected?

Even with a thorough survey, some factors can extend a rewire beyond the initial programme. Being aware of these helps you build a sensible contingency.

Unexpected wiring condition. In older properties, the full condition of original wiring is not always visible until walls are opened or floors lifted. Where cables are in worse condition than anticipated, the strip-out takes longer. A reputable electrician will discuss any changes to programme promptly rather than letting them emerge as a surprise at the end.

Access complications. Cables expected to run through a ceiling void but encountering unexpected obstructions, floors that cannot be lifted without structural complications, or service routes that turn out to be blocked are not uncommon in older buildings and can add time.

Additional work identified during the job. A rewire sometimes reveals related issues — inadequate earthing to plumbing, damaged accessories that need replacement, or additional circuits not apparent at survey stage. We discuss any such findings with you immediately and agree the approach before proceeding.

How Does a Rewire Fit With Renovation Work?

If you are rewiring as part of a broader renovation — a kitchen replacement, an extension, a full redecoration — the sequencing matters. The rewire should be completed before plastering and decoration begins, as it will require chasing into walls and lifting floors that will need to be made good. The correct sequence is: rewire first, then plastering and making good, then decoration.

If you are installing an EV charger or solar panels at the same time as a rewire, this is the ideal moment to include those circuits in the rewire scope. The marginal cost of adding an EV charger circuit or solar panel connection while walls are already open is significantly lower than returning to do it later.
