How Long Does a House Rewire Take in Gravesend? | Local Electrician’s Guide
The question homeowners across Gravesend ask most often about rewiring is not the cost — it is how long the house will be disrupted. A rewire touches every room, involves chasing cables into walls, lifting floorboards, and temporarily disconnecting circuits that your household relies on every day. Understanding exactly what happens at each stage, how long each phase takes, and what level of disruption to expect at each point helps you plan around the work rather than being caught off guard by it.
Gravesend’s housing stock spans Victorian terraces through the town centre and along the older streets, inter-war semis across the established residential areas, post-war estates through Riverview Park, Singlewell, and Northfleet, and newer developments on the expanding edges. Each property type presents different working conditions that affect how long the rewire takes. This guide sets out realistic timescales for different property sizes and walks through every stage of the process.
Total Timescales by Property Size
The complete rewire process — from the electrician starting first fix to receiving your final certificate — includes the electrical work itself, plastering between stages, drying time, and second fix completion. Here is what to expect across Gravesend.
A two bedroom flat or terraced house takes roughly two to three weeks from start to certification. The electrical first fix takes three to four days. Plastering follows within a day or two. Drying time takes three to five days. Second fix takes one to two days. Testing and certification complete on the final day of second fix.
A three bedroom semi-detached house — the most common property type we rewire across Gravesend — takes roughly three to four weeks. First fix takes four to six days. Plastering takes one to two days. Drying takes four to seven days. Second fix takes two to three days. This is the timescale most Gravesend homeowners should plan around.
A four bedroom detached house takes roughly four to five weeks. First fix takes five to seven days. Plastering takes two to three days because there is more wall area to make good. Drying takes five to seven days. Second fix takes two to three days.
A five bedroom or larger property can take five to seven weeks depending on the size, the number of floors, and any complications the building presents.
These are total elapsed timescales — the electrician is not on site every day because the plastering and drying stages sit between first and second fix. The property is liveable throughout.
Stage 1: Assessment and Planning (One to Two Hours)
Before any physical work begins, the electrician visits to assess the existing installation and plan the new one. This involves inspecting the current consumer unit, checking cable types in the loft and behind accessible sockets, testing a sample of circuits, and assessing the earthing and bonding throughout.
The planning conversation happens during or immediately after this visit. You walk through every room with the electrician and decide where sockets, switches, and lighting will go in the new installation. This is the most important stage for getting the result you want — every decision made now costs very little to implement. The same decisions made after plastering cost significantly more.
Take your time with this stage. Think about where you charge your phone, where you plug in the lamp, where the television sits, where the desk goes in the home office, which rooms need dimmer switches, where you have always wished there was a socket but never had one. The electrician translates your requirements into a circuit design that forms the blueprint for the entire rewire.
Stage 2: First Fix (Three to Seven Days)
First fix is where the visible disruption happens. The old consumer unit is removed. Existing cables are stripped out circuit by circuit. New cables are installed throughout the property — chased into walls, run through floor voids beneath lifted floorboards, and routed through the loft space to reach first floor rooms and lighting positions.
Wall chasing is the messiest element. A mechanical chaser cuts parallel grooves into the plaster and masonry, creating channels where the cables sit before being plastered over. The dust generated is fine and persistent — it spreads despite dust sheets and protective covering. This is unavoidable and is the primary source of disruption during a rewire.
Gravesend’s different housing types affect how long chasing takes. The Victorian terraces around the town centre and through the older streets have solid brick walls that take longer to chase than modern plasterboard. The inter-war housing across Perry Street and the established residential areas typically has a mix of solid external walls and stud internal partitions. The post-war estates through Riverview Park and Singlewell have more predictable construction that is quicker to work through.
Floorboard lifting is needed to run cables between rooms and from floor to floor. The electrician lifts boards strategically along cable routes rather than taking up every board in every room. The boards are refixed after cables are installed, and any boards that are damaged during lifting are replaced.
The electrician works room by room. While one room is being rewired, the rest of the house maintains power through temporary connections. Each evening, the electrician ensures you have lighting and enough working sockets to function normally — kettles, phone chargers, the television, the fridge and freezer. You are never left without power overnight.
The first fix stage is the phase to plan around carefully. If you work from home, set up your workspace in a room scheduled for later in the programme. If you have young children, keep them away from the rooms being worked on during the day. The dust and temporary disruption are manageable with a little forward planning.
Stage 3: Plastering (One to Three Days)
Once first fix is complete, the plasterer arrives to make good every chased channel and every new back box position. The channels are filled, damaged plaster around the chasing is repaired, and any areas needing a skim coat are finished to a smooth surface ready for decoration.
The extent of plastering depends on how much chasing was needed and the condition of the existing plaster. Gravesend’s Victorian properties with original lime plaster sometimes need more extensive repair where the chasing has disturbed a wider area than the channel itself. Modern plasterboard walls typically need minimal making good because the chasing is cleaner and more contained.
The plastering stage is quick — one day for a two bedroom property, two to three days for a larger house. The disruption is modest compared to first fix because the work is quieter and generates much less dust.
Stage 4: Drying Time (Three to Seven Days)
This is the stage where nothing visible happens but the timeline cannot be compressed. Fresh plaster needs to dry before the electrician fits faceplates, switches, and light fittings against it. Fitting onto damp plaster causes staining on the faceplates, potential corrosion of metal components, and a poor bond between the fitting and the wall.
Drying time depends on the amount of plaster applied, the room temperature, ventilation, and the time of year. In summer with windows open, three to four days is often sufficient. In winter with lower temperatures and less ventilation, five to seven days is more realistic. Opening windows and maintaining reasonable heating speeds the process without forcing it.
This drying period is actually the least disruptive phase of the entire rewire. The mess of first fix is over, the plastering is finished, and the house is essentially waiting for the final stage. Many Gravesend homeowners use this period to start decorating the rooms that are fully dry while waiting for others to catch up.
Stage 5: Second Fix (Two to Three Days)
Second fix is when the rewire comes together visually. The electrician returns and installs every visible element — socket faceplates, light switches, dimmer plates, ceiling roses, light fittings, the cooker connection point, the shower unit connection, and smoke and heat detectors throughout the property.
This phase is clean, quiet, and quick compared to everything that preceded it. No chasing, no dust, no lifted floorboards. The electrician works systematically through each room, connecting faceplates, hanging fittings, and commissioning each circuit. The transformation from bare walls with cables protruding to a finished room with working sockets and new light fittings is visible and satisfying.
Second fix on a three bedroom Gravesend house typically takes two to three days. A two bedroom property completes in one to two days. Larger properties take three days.
Stage 6: Testing and Certification (Half Day)
The final stage tests every circuit comprehensively. The electrician measures continuity on every cable run, insulation resistance on every circuit, earth fault loop impedance at every point, and polarity at every socket and fitting. RCDs and RCBOs are tested to confirm they trip within the millisecond timeframes Building Regulations require.
The results are recorded on an Electrical Installation Certificate — the formal document confirming the installation meets current BS 7671 wiring regulations. This certificate is important for your records, your insurance, and future property sales. Keep it permanently with your property documents.
If the electrician is registered with a competent person scheme, they self-certify the work and notify building control on your behalf. If not, you need a separate building control inspection that adds cost and time to the programme.
Living Through Each Stage
Most Gravesend homeowners stay in the property throughout the rewire. The key to managing the disruption is understanding which stage you are in and what to expect from each.
During first fix — accept that the rooms being worked on are temporarily a construction zone. Set up a base in a room scheduled for later. Cover furniture and belongings in adjacent rooms to protect against dust migration. The electrician maintains power to non-working rooms every evening.
During plastering — the disruption drops significantly. The plasterer works through the patching and skimming quickly and the mess is minimal compared to first fix.
During drying — the house is quiet. Use this period to start decorating rooms where the plaster is dry. Open windows to improve ventilation and speed drying where practical.
During second fix — the electrician moves room by room fitting faceplates and fittings. Each room is completed and functional as they progress through the house. By the end of second fix, every room has working sockets, lighting, and switches.
How to Minimise the Total Timeline
Have the plastering scheduled before first fix finishes. The gap between the electrician completing first fix and the plasterer arriving is dead time that extends the programme unnecessarily. Book the plasterer in advance based on the electrician’s estimated first fix completion date.
Make all specification decisions before first fix starts. Changing socket positions, adding dimmers, or relocating switches after chasing has been completed means opening up finished work — adding time and cost.
Order light fittings and any special faceplates early. Non-standard items with delivery lead times can delay second fix if they arrive after the electrician is ready to install them.
Coordinate decoration promptly after second fix. The rooms are ready for painting as soon as the faceplates and fittings are installed. Completing decoration while the rewire is fresh keeps the overall improvement programme moving.
