How Long Does It Take to Rewire a House?

How Long Does It Take to Rewire a House in Milton Keynes?


A full house rewire is the most comprehensive electrical upgrade you can carry out on a property, and the question most Milton Keynes homeowners ask before anything else is how long it’s going to take. Not the cost — that comes second. The first concern is always the disruption. How many days will the electrician be in the house? How long will rooms be out of action? When will the plastering happen? And critically, how long from start to finish before everything is back to normal?

The honest answer is that it depends on the size of your property, the type of construction, the number of circuits you need, and how quickly the plastering is arranged between the two electrical stages. But unlike a renovation where timescales can drift unpredictably, a rewire follows a structured sequence that’s predictable once you understand the stages involved. This guide sets out realistic timescales for different property sizes across Milton Keynes, explains what happens at each stage, and helps you plan around the work so your household keeps functioning throughout.

Timescales by Property Size

Milton Keynes has a distinctive housing mix compared to many UK towns. Much of the housing stock dates from the 1970s onwards — the original new town estates in Bradwell, Stony Stratford, Wolverton, and Bletchley, through to the later developments in Emerson Valley, Kingsmead, Oxley Park, and Brooklands. There’s also older housing in the established towns that predated the new city — Victorian and Edwardian properties in Wolverton and Stony Stratford, inter-war housing in Bletchley and Fenny Stratford. Each construction type affects how long the electrical work takes.

A two bedroom flat or terraced house typically takes three to five days for the electrical work. Properties of this size need six to eight circuits, and the cable runs are shorter and more straightforward than in larger homes. Many of Milton Keynes’s original new town properties — the compact terraces in Netherfield, Coffee Hall, and Beanhill — fall into this bracket.

A three bedroom semi-detached or terraced house takes five to eight days. This is the most common property size we rewire across Milton Keynes, covering the housing across Bradwell, Two Mile Ash, Oldbrook, Fishermead, and dozens of similar estates. These properties typically need eight to ten circuits and the work is predictable because the construction methods across the new town estates are consistent and familiar.

A four bedroom detached house takes seven to ten days. The additional rooms, longer cable runs, and typically more complex circuit requirements — multiple bathroom circuits, dedicated supplies for home offices, electric vehicle charger circuits — all add to the programme. The larger detached properties in areas like Shenley Brook End, Loughton, Great Linford, and Middleton sit in this range.

A five bedroom or larger property takes ten to fourteen days depending on the size, the number of bathrooms, the length of cable runs, and any additional requirements like outbuilding supplies or extensive outdoor lighting. The largest properties in areas like Woburn Sands, Newport Pagnell, and the villages surrounding Milton Keynes may need two full weeks of electrical work.

These timescales cover the electrician’s time on site only. The total elapsed time from starting to completion — including plastering and drying between the two electrical stages — is typically two to four weeks depending on how quickly the plastering is scheduled.

Stage One: Planning and Preparation

Before the electrician arrives, there’s a planning phase that most homeowners underestimate in its importance. This is where you discuss and agree the positions of every socket, switch, and light fitting in the finished installation. Where do you want double sockets? Where do you need USB charging points? Which lights should be on dimmer circuits? Do you want sockets in places the original installation didn’t cover — inside wardrobes for charging, behind TV positions for media equipment, in the kitchen island for appliances?

These decisions are cheapest and easiest to implement during the rewire. Adding a socket after the plastering is done means cutting into a freshly finished wall, which wastes time and money. Spend an hour walking through the house with your electrician before work starts, discussing every room and agreeing the final positions. This planning session costs nothing but saves significant hassle during the build.

Allow a day or two before the electrician starts to prepare each room — moving furniture to the centre or into completed rooms, taking down curtains and pictures, and clearing access to the walls and floors the electrician needs to reach.

Stage Two: First Fix

First fix is where the real work happens and where the disruption is concentrated. The electrician removes the old wiring, installs the new consumer unit, and runs new cables throughout the property to every socket, switch, and fitting position.

This involves chasing channels into walls to route cables, lifting floorboards to run cables through floor voids, and routing cables through the loft space. The consumer unit is installed and all circuits are connected at the board. Cables are left protruding at every socket and switch position, ready for the faceplates to be fitted during second fix.

The construction type of your Milton Keynes property significantly affects how long first fix takes and how much disruption it generates. The timber-framed construction used in many of the original new town estates allows cables to be run inside wall cavities without extensive chasing, which is faster and less messy than routing through solid masonry. The brick-built properties in Wolverton, Stony Stratford, and Bletchley require more chasing because cables need cutting into solid walls. Newer properties with plasterboard on stud walls are somewhere in between — cables can often be fished through the cavity without chasing, but additional work is needed where fire barriers and insulation restrict access.

First fix is noisy and dusty regardless of construction type. Chasing generates fine dust that spreads despite protection measures. If possible, close internal doors to contain dust to the room being worked on and keep windows open for ventilation. The electrician works room by room, completing one area before moving to the next, so the disruption moves through the house progressively rather than affecting everywhere simultaneously.

Stage Three: Plastering

Once first fix is complete, the plasterer makes good every surface where cables have been chased. For a standard three bedroom house, plastering takes one to two days depending on the extent of the chasing. Properties with solid walls that required more chasing need more plastering than timber-framed properties where cables were routed through cavities.

After plastering, the walls must dry before second fix can proceed. Drying time varies with the season and ventilation — two to three days in warm, well-ventilated conditions during summer, up to five to seven days in colder months with limited airflow. This is dead time in terms of visible progress but it’s essential. Fitting faceplates onto damp plaster traps moisture and causes problems. Painting over damp plaster leads to peeling and adhesion failure.

Coordinating the plasterer promptly after first fix completion minimises the gap between the two electrical stages. Your electrician should give you advance notice of when first fix will finish so the plasterer can be booked to start the following day or within a day or two, keeping the overall programme as tight as possible.

Stage Four: Second Fix

Second fix is the clean, satisfying stage where the house starts looking finished. The electrician returns and fits all the visible elements — socket faceplates, light switches, ceiling roses, light fittings, the consumer unit cover, and any accessories like shaver sockets, cooker switches, and fused spurs. Appliances are connected — the cooker, shower, extractor fans, and smoke and heat detectors.

Second fix typically takes one to two days for a three bedroom house. The work is clean and quiet — no chasing, no dust, no lifted floorboards. By the end of this stage your new installation is physically complete and ready for testing.

Stage Five: Testing and Certification

Once everything is connected, the electrician carries out comprehensive testing of every circuit. This involves measuring insulation resistance, earth fault loop impedance, continuity of protective conductors, polarity checks, and RCD trip time verification. Every circuit must pass before the installation can be certified.

Testing takes half a day to a full day depending on the number of circuits. Once all tests pass, the electrician issues an Electrical Installation Certificate — the formal document confirming your installation meets current BS 7671 standards. This certificate is essential for insurance purposes, future property sales, and evidence that the work has been properly completed and independently verified through testing.

What Can Extend the Timeline?

Several factors push the programme beyond standard timescales.

Discovery of unexpected issues during first fix — asbestos in unexpected locations, structural problems revealed when floorboards are lifted, previous electrical work done in non-standard ways that needs untangling — can add time. Experienced electricians working across Milton Keynes’s housing stock anticipate common issues with specific construction types, but genuinely unexpected discoveries do occur.

Late decisions about socket and switch positions cause delays if the electrician has to revisit completed rooms to add or move outlets. Finalising every position before first fix starts eliminates this entirely.

Plastering delays are the most common cause of extended programmes. If the plasterer isn’t booked promptly or cancels at short notice, the gap between first and second fix stretches. Your electrician should coordinate closely with the plasterer to prevent this, but it’s worth confirming the plastering schedule before the rewire starts.

Decoration after second fix isn’t part of the electrical programme but affects when the house feels fully finished. Chased and plastered walls need repainting, and some homeowners choose to redecorate entire rooms while the furniture is already moved and the walls are freshly plastered. Building this into your overall timeline prevents the rewire feeling like it’s dragging on when the electrical work is actually complete.

Living Through the Rewire

The vast majority of Milton Keynes homeowners stay in their property during a rewire. The electrician maintains power to rooms not being worked on, so you always have lighting and socket availability in the evenings. Setting up a temporary base in a room scheduled later in the programme gives you a clean, functional retreat during the day. Keeping a kettle, microwave, and phone chargers accessible maintains a basic level of domestic normality throughout.

Discuss the room-by-room programme with your electrician before they start. Knowing which rooms are affected each day lets you plan meals, work-from-home arrangements, and family routines around the work. The disruption is real but predictable, and most homeowners who’ve been through it say the anticipation was worse than the reality.
