Plan the electrical scope before finishes are fixed
Electrical work is easier to control when it is planned as part of the refurbishment rather than treated as a series of late decisions after walls, ceilings, joinery and decoration are complete. Start with how each room will be used and which fixed electrical functions need to be coordinated with it.
The objective is not to design the electrical installation yourself. It is to give the responsible electrician and project team a clear brief before routes, positions and finished surfaces become difficult to change.
- Record the rooms and areas affected by the refurbishment.
- Identify intended lighting, socket, appliance, data and control requirements at a functional level.
- Flag fitted furniture, kitchens, bathrooms and external areas that create interfaces with electrical work.
- Record decisions that are still open so they are not mistaken for fixed scope.
Understand the existing installation before adding to it
A refurbishment can expose questions about an existing consumer unit, circuits, accessories or previous alterations. Age alone does not determine what must be replaced, and a new room layout does not automatically mean that the whole property needs rewiring.
Ask the electrician responsible for the work what existing information or inspection is needed to define the proposed additions safely. Where further investigation is recommended, keep that separate from assumptions about the final installation scope.
- Provide any available electrical certificates or previous inspection records.
- Identify known faults, nuisance tripping or areas that have already been altered.
- Separate observed issues from conclusions about their cause.
- Do not assume that a consumer-unit change or full rewire is required without assessment.
Confirm the compliance route and who is responsible
For ER Group London's England-based service area, electrical installation work in dwellings falls within the electrical-safety requirements of the Building Regulations. Not every item of electrical work has the same notification requirement, so the route should be confirmed from the actual scope rather than from a generic checklist.
A suitably registered installer can self-certify qualifying work through an authorised competent-person scheme. Other work may follow a Building Control or other permitted certification route. The written scope should identify who is responsible for the electrical work, testing, notification where required and the completion documents.
- Ask which person or business is responsible for the electrical installation work.
- Check the relevant competent-person registration where that route is being used.
- Confirm whether the proposed work is notifiable and who will deal with any notification.
- Ask what test and completion documentation should be provided for the agreed work.
Coordinate electrical work with carpentry, plastering and decoration
Electrical positions affect more than the electrical trade. Fitted joinery, wall panelling, kitchen units, mirrors, sanitaryware, radiators, curtains, artwork and decorative lighting can all change where accessories or services need to be considered.
Agree the interfaces before final making good. This reduces avoidable opening-up of newly repaired walls and ceilings and makes responsibility clearer where one trade provides a route or finish for another.
- Coordinate socket and switch positions with fixed furniture and joinery.
- Identify where walls or ceilings may need controlled opening and reinstatement.
- Resolve appliance, lighting and control positions before final decoration where practical.
- Keep making-good responsibility explicit in the written scope.
Treat period and listed fabric as a design constraint
In a period home, the shortest service route is not automatically the right project decision. Decorative plaster, panelling, historic joinery, retained floor finishes and other significant fabric may change how the project team approaches access and reinstatement.
If the property is listed, alterations that affect its special architectural or historic character can require Listed Building Consent. The relevant professional adviser or local planning authority should determine that boundary; an electrical contractor should not be expected to make a heritage-consent decision outside the agreed role.
- Identify fabric that the client or professional team intends to retain.
- Raise access and routing conflicts before finishes are disturbed.
- Record any architect or conservation requirements that affect the electrical scope.
- Do not assume that an internal alteration is exempt from listed-building controls.
Agree testing, certification and handover
Completion is more than fitting the final accessories. The responsible electrician should determine the appropriate inspection and testing for the work and the documentation that follows from it. The exact certificate depends on the scope and compliance route.
Keep the documents with the property records. They can help future electricians, owners and professional advisers understand what work was carried out and how it was recorded at the time.
- Ask what electrical certificate or record will follow the completed work.
- Confirm who provides any Building Regulations compliance documentation where applicable.
- Record circuit, accessory or control information that is useful for handover.
- Keep final documents with the wider refurbishment records.
Compare written scope, not a single headline figure
Two electrical quotations may describe very different responsibilities. Compare the proposed work, fixtures, access assumptions, testing, making good, exclusions, provisional items and coordination with other trades before comparing the final figure.
For an occupied or high-value home, sequencing, protection and communication can be material parts of the project even though they do not appear as electrical components.
- Check what is supplied and what is client-supplied.
- Clarify access, protection and making-good assumptions.
- Identify testing, notification and handover responsibilities.
- Agree how changes to the electrical brief will be recorded.
Information to prepare before electrical work is scoped
A clear room-by-room brief helps the electrician and wider refurbishment team identify interfaces before finishes are committed.
- Rooms and areas affected by the refurbishment
- Existing drawings and electrical certificates if available
- Known faults or previous electrical alterations
- Functional lighting, socket, appliance, data and control requirements
- Kitchen, bathroom and fitted-furniture layouts where relevant
- Sensitive walls, ceilings, floors, joinery or decorative finishes
- Any architect, designer or conservation requirements
- Occupancy, access and protection constraints
- Making-good and decoration responsibilities
FAQs
FAQs
-
No. Electrical installation work must comply with the applicable Building Regulations, but notification requirements depend on the type and location of the work and the compliance route being used. Ask the responsible electrician to confirm the position for the actual scope before work begins.
-
ER Group recommends using an appropriately competent registered electrician for domestic electrical installation work. Where a competent-person self-certification route is being used, check that the installer is registered for the relevant work.
-
That depends on the work carried out. The responsible electrician should state the inspection, testing and certificate or record that applies, together with any Building Regulations compliance document required by the chosen route.
-
As early as practical and before final joinery, plaster repairs or decoration close off the relevant interfaces. Late changes can create avoidable opening-up and making good.
Next Steps
Plan Electrical Work Within the Wider Refurbishment
If electrical work forms part of a private-home refurbishment, share the room plans, known issues, finish requirements and available property information so the scope can be coordinated with the wider programme.
