How Long Does a House Rewire Take? What Gravesend Homeowners Should Expect
A full house rewire is one of those projects that homeowners delay partly because of the cost but mostly because of the disruption. The idea of every room being pulled apart, cables running through walls and ceilings, floorboards lifted, and plaster chased out sounds like weeks of chaos that you’d rather not face. The reality is more manageable than most people expect — but only if you understand what’s involved, how long each stage takes, and how to plan around the work so your household keeps functioning throughout.
This guide sets out realistic timescales for rewiring different sized properties across Gravesend, explains what happens at each stage, and gives you practical advice on living through a rewire with as little disruption as possible.
The Short Answer
A two bedroom flat or terraced house typically takes three to five days for the electrical work. A three bedroom semi-detached house — the most common property we rewire across Gravesend — takes five to eight days. A four bedroom detached house takes seven to ten days. A five bedroom or larger property can take ten to fourteen days depending on the size and complexity.
These timescales cover the electrical first fix and second fix only — the days when the electrician is physically on site working. Between first fix and second fix, your plasterer needs to make good the chased walls, which adds time to the overall programme but isn’t electrical work. The total elapsed time from starting the rewire to having everything finished and certified is typically two to four weeks depending on how quickly the plastering is scheduled and how long it takes to dry.
Stage One: First Fix
First fix is the disruptive stage. This is where the old wiring is removed and all new cables are installed throughout the property. The electrician chases channels into walls to route cables to every socket, switch, and light fitting position. Floorboards are lifted to run cables through the floor voids. Cables are routed through the loft space to serve the upstairs lighting circuits. The new consumer unit is installed and all circuits are connected.
For a three bedroom semi in Gravesend, first fix typically takes four to six days. The electrician works room by room, completing one area before moving to the next. This methodical approach means you always have functioning power in the rooms not currently being worked on.
The amount of chasing required depends on the property’s construction. Properties with stud partition walls — common in many of Gravesend’s post-war housing across Riverview Park, Singlewell, and Northfleet — allow cables to be run inside the wall cavity without visible chasing, reducing both disruption and the amount of plastering needed afterwards. Solid brick walls — typical of the Victorian and Edwardian terraces around the town centre, Windmill Street, and Pelham Road — require more chasing because every cable route needs cutting into the brickwork. Lath and plaster walls, found in many older Gravesend properties, need particular care because the lath can crack and break away from the plaster if the chasing isn’t done carefully.
First fix is noisy and dusty. There’s no avoiding that. Chasing into walls generates fine dust that gets everywhere despite dust sheets and protection. If you have the option to vacate the room being worked on for the day, that makes things easier for both you and the electrician.
Stage Two: Plastering
Once first fix is complete, the plasterer comes in to make good every wall where cables have been chased. This typically takes one to two days for a standard three bedroom house, though it depends on the extent of the chasing and whether full walls need skimming or just the chased channels need filling and patching.
After plastering, the walls need to dry before decoration or second fix can happen. Drying time depends on the season, ventilation, and the thickness of the plaster. In warm, well-ventilated conditions, two to three days is usually sufficient for the thin skim over chased channels. In colder months or in rooms with limited airflow, five to seven days is more realistic. Rushing this stage causes problems — fitting socket faceplates onto damp plaster traps moisture behind them, and painting over damp plaster causes peeling and adhesion failure.
This drying period is dead time in terms of visible progress, but it’s a necessary part of the process. Your electrician and plasterer should coordinate their schedules so the plastering happens promptly after first fix, minimising the gap between the two electrical stages.
Stage Three: Second Fix
Second fix is the clean, fast, satisfying stage. The electrician returns once the plastering is dry and fits all the visible elements — socket faceplates, light switches, ceiling roses, light fittings, and the front cover of the consumer unit. Appliances are connected — the cooker, shower, extractor fans, and smoke detectors. Everything is wired, connected, and made ready for testing.
Second fix typically takes one to two days for a standard three bedroom house. The work is clean and quiet compared to first fix — no chasing, no dust, no lifted floorboards. The electrician works through the house fitting and connecting, and by the end of this stage your new installation is physically complete.
Stage Four: Testing and Certification
Once second fix is finished, the electrician carries out comprehensive testing of every circuit in the installation. This involves testing insulation resistance, earth fault loop impedance, continuity of protective conductors, polarity, and RCD trip times. Every circuit must pass before the installation can be certified.
Testing takes half a day to a full day depending on the size of the installation and the number of circuits. Once all tests pass, the electrician issues an Electrical Installation Certificate — the formal document confirming your new installation meets current BS 7671 standards. This certificate is important for insurance purposes, future property sales, and your own peace of mind that the work has been done properly and verified through testing.
What Affects the Timeline?
Several factors can extend or shorten the overall programme beyond the standard timescales.
Property size is the most obvious variable. More rooms mean more circuits, more cable, and more labour. But the relationship isn’t perfectly linear — a four bedroom house doesn’t take exactly twice as long as a two bedroom house because certain fixed tasks like installing the consumer unit and setting up only happen once regardless of property size.
Property age and construction matter significantly. Older properties with solid walls, lath and plaster, and non-standard construction take longer than modern plasterboard and stud construction. The Victorian and Edwardian terraces across central Gravesend and Northfleet generally take longer to rewire than the post-war housing in Riverview Park or the newer builds in Ebbsfleet because the cable routing is more labour-intensive and the making good is more involved.
Accessibility affects the pace of work. Clear, empty rooms allow the electrician to work efficiently. Rooms full of furniture that needs moving and protecting slow things down. If you can clear rooms ahead of the electrician’s schedule — emptying the room being worked on the following day — the work progresses faster and the risk of accidental damage to your belongings drops significantly.
The number of sockets, switches, and circuits you want in the finished installation affects the first fix duration. A basic like-for-like rewire replaces the existing positions. Most homeowners take the opportunity to add sockets where they’ve always wanted them, upgrade to doubles where singles currently sit, add USB charging outlets, and install dimmer switches. Each addition is individually minor but collectively they add cabling and connection time across the whole house. Planning your positions before the electrician starts means these extras are built into the programme rather than added as afterthoughts that extend the timeline.
Living Through a Rewire
Most Gravesend homeowners stay in the property during a rewire, and with some planning it’s perfectly manageable. The electrician works room by room, maintaining power to the areas you’re using while working on others. You’ll always have lighting and at least some socket availability in the evenings.
A few practical steps make the experience more comfortable. Clear each room before the electrician reaches it — move furniture to the centre and cover it with dust sheets, or ideally move it to a room that’s already been completed. Set up a temporary living area in a room that’s scheduled later in the programme so you have a clean, functioning space to retreat to during the day. Keep a kettle, microwave, and essential appliances accessible throughout.
Discuss the programme with your electrician before they start. Know which rooms are being worked on each day so you can plan accordingly. If you work from home, schedule your most important calls and meetings for days when the electrician is in a different part of the house.
The disruption is real but temporary. A week of inconvenience delivers decades of safe, reliable electrics throughout your home. Most homeowners who’ve been through it say the anticipation was worse than the reality, and the relief of having a fully certified modern installation makes the few days of disruption well worth enduring.
