Condition or recurring concerns
Previous findings, deterioration, damaged accessories or repeated electrical issues can all change what should be investigated before a wider renewal is agreed.
Inspection & testing →JSR ELECTRICAL · REWIRING
Rewire around what the property needs next.
A rewire is disruptive enough. The scope should be planned around the installation, the way the property will be used and the work happening around it — not around a generic package.

START WITH WHY
Age alone does not decide the scope.
The reason for the enquiry matters. JSR starts with what is changing, what is known about the installation and what the property needs to support next.
Renovation or a new layout
Moving rooms, kitchens, lighting, sockets or fixed equipment is the point to plan the electrical layout around how the finished property will actually work.
Future electrical demand
Planned circuits, charging, controls and other future electrical requirements should be considered before walls and finishes are closed back up.
PLAN BEFORE DISTURBING FINISHES
The cable route is only one part of the job. Access, occupation and the finished layout matter too.
WHAT HELPS US PLAN
Tell us how the property has to work during and after the rewire.
Rewiring can affect walls, ceilings, floors and occupied spaces. The earlier JSR understands the property and the wider programme, the clearer the electrical scope can become.
- Whether the property is occupied, vacant or part of an active renovation.
- Which rooms or circuits are in scope and what other trades or works are happening.
- Where sockets, lighting, controls and significant electrical loads need to serve the finished space.
- Any reports, drawings, previous test information or known limitations that help establish the starting point.
SCOPE BEFORE DISRUPTION
Renew what needs renewing. Design what needs changing.
The right answer may be a broader rewire or a more targeted electrical renewal. The agreed scope follows the condition, the planned changes and the circuits involved.
Existing installation
Known defects, testing information, earthing and bonding, circuit condition and existing protection help establish what can remain and what needs attention.
New electrical layout
Socket positions, lighting points, controls and new circuit requirements are considered as part of the finished property rather than added as an afterthought.
Access & making good
Access routes, interaction with finishes and any making-good responsibilities need to be clear in the agreed scope so the customer knows where the electrical work starts and stops.
HOW IT MOVES FORWARD
Assess. Design. Install and test.
A rewire should move from evidence and requirements into an agreed plan before disruptive work begins.
- 01 · ASSESSUnderstand the property.
Share what is prompting the enquiry, what is changing and any information already available. JSR establishes what needs checking before the scope is agreed.
- 02 · DESIGN & AGREESet the electrical scope.
The circuits, points, protection, access requirements and relevant coordination are agreed around the intended use of the property.
- 03 · INSTALL & TESTComplete and hand over.
The agreed work is installed, inspected and tested as required, with certification and next steps provided through the appropriate route.
REWIRING ENQUIRY
Tell us what is changing in the property before we talk about cable.
Electrical work is assessed against the requirements applicable to the installation and the work at the time. In England, installation of a new circuit is notifiable building work under Part P, so rewiring that includes new circuits follows the appropriate certification and notification route. Official Part P guidance ↗ Specific access, making-good responsibilities, availability, price and scope are confirmed as part of the agreed job.
