Plan how you will use the home, not just socket numbers
Start with a furniture plan and appliance list. Locate the kitchen, desk, beds, router, washing machine, water heater and air conditioner. Equipment with special requirements needs a specific model or technical data. This lets the electrician design for actual use rather than mechanically placing sockets around the perimeter.
The owner describes the need; the specialist determines the design, protection, cables, load distribution and checks. Do not copy a circuit arrangement from someone else’s apartment: the incoming supply, existing wiring and equipment may differ. If permitted supply capacity must change, establish the distribution operator’s procedure separately.
A requirements table for the electrician
| Area | Information to give | Questions to resolve |
|---|---|---|
| Kitchen | Hob, oven, dishwasher and refrigerator models | Connection requirements, point locations and access |
| Bathroom | Water heater, washing machine, lighting and ventilation | Permitted positioning and protection for the actual conditions |
| Workspace | Computer, monitor and network equipment | Normal and backup operating scenarios |
| Bedrooms and circulation | Furniture, light controls and device charging | Usability after furniture installation |
| Backup power | Required devices, runtime and whether interruption is acceptable | System type, integration, location and limitations |
Add a diagram of existing points, a photograph of the consumer unit without dismantling it, and available documents. Do not open or test electrical equipment to prepare this list; inspection belongs to the specialist.
Decide what is essential during an outage
Separate essential loads, desirable loads and those that can wait. One household may only need connectivity and a workspace; another needs a refrigerator or special equipment. A powerful heating appliance is not equivalent to phone charging: it changes system requirements and cost.
State the expected runtime and whether interruptions are acceptable. Ask the specialist to assess appliances’ running and starting power, the system’s usable stored energy, losses and the ability to recharge in time. Power in watts (W) and stored energy in watt-hours (Wh) or kilowatt-hours (kWh) are different measures. The first helps assess which appliances the system can power; the second helps estimate runtime, taking load and losses into account. One number on a box does not guarantee the required runtime.
Compare three complete options, not equipment alone
| Option | Costs to establish |
|---|---|
| Power for individual devices | Compatible equipment, required approved accessories, location and operating conditions |
| Preparation for a future fixed system | Design, preparatory work now and exactly what remains to purchase |
| A complete fixed system | Equipment, associated materials, installation, configuration, checks, documents and maintenance |
DTEK’s commercial Energy Box description includes installation and commissioning alongside equipment supply. This is a useful scope check for any proposal: a seller quoting only an inverter and battery has not yet established the cost of a ready-to-use system. A brand name alone does not demonstrate suitability for your brief.
What belongs in an electrical estimate?
- Survey, design decisions and an agreed work schedule.
- Cables, routes, preparation and reinstatement, with clear responsibility.
- A consumer unit and protective devices specified in detail, rather than an undefined “controls” line.
- Boxes, mechanisms, frames, lights and connections: what labour includes and what you buy.
- Backup power and auxiliary equipment, if included in this stage.
- Checks, tests, labelling, as-built records and handover.
Ask what “one point” includes: preparation, cable, box, fitting, connection and checking? Different definitions make rate comparisons meaningless. Establish who makes good chases and finishes: the electrician, main crew or another contractor.
When changes are still easier to make
- Before concealed work: agree furniture, appliances and the backup scenario.
- Before routes are covered: obtain the agreed checks, photographs and drawings.
- Before buying final fittings: confirm compatible product ranges and quantities.
- Before fitting furniture: check access to connection points and equipment.
- At handover: obtain clear labels, instructions and maintenance arrangements.
“We will add it after painting” can mean paying again for removal, preparation and finishing. If you will buy equipment later, agree the limits of preparation now and explicitly record what remains unresolved.
Avoid counting costs twice
Use separate groups for labour, installation materials, final fittings and the backup system. Each cable or connection should belong to one agreement only. If the owner supplies equipment, remove its supply cost from the contractor’s price while retaining the agreed installation.
In Reno Pro, link these items to the electrical stage and keep models and approvals in notes. A supplier invoice, a recorded payment and completed work are separate events. Keep documents and check the result with the responsible specialist before closing the stage.
