Certified Electrician – Inspection & Testing Qualified

Electrical Installation Design – Houses, Flats, Commercial Premises

Designing an electrical installation is a key element in the construction or renovation of any building. This applies to single-family houses and flats, as well as commercial or office spaces. A professionally prepared design ensures safety, compliance with regulations, and everyday comfort of use. Thanks to it, the electrical system will be efficient, functional, and ready for technical inspection without unpleasant surprises. I also offer audits and modernisation of existing electrical systems to bring them up to modern standards and user requirements.

Scope of Electrical Design Services

The service includes a comprehensive design of the electrical system in the building – from the main supply connection, through consumer units and wiring, to the final outlets (sockets, lighting, appliances). The design covers the layout of all components, division into circuits, and the selection of appropriate protection devices suited to the expected loads.

1. Houses – full energy demand planning, special installations, three-phase connection.
2. Flats – ergonomic layout of outlets, often modernisation of old wiring systems.
3. Commercial premises – tailored design considering the specifics of the business, H&S and fire safety requirements.

Cooperation with the Client

The key to a successful project is close cooperation with the client. We start with a detailed consultation to understand the client’s needs and expectations. We analyse the architectural documentation of the building, and during the design phase we maintain regular contact, presenting concepts and agreeing on details.

Legal and Regulatory Compliance

Every project must comply with current legislation, electrical standards, and local connection requirements. The design documentation must be prepared by a qualified professional holding electrical engineering certification.

Technical Documentation

Technical documentation is the final product of the design process, essential for installation work and for the acceptance of the system.

1. Technical description – system parameters, design assumptions.
2. Engineering calculations – load, cable cross-sections, protective measures.
3. Diagrams and plans – layout of electrical points, cable routes, consumer units.
4. Material list – cables, fittings, protective devices.

Stages of Electrical Design and Installation

1. Needs analysis – consultation with the client, review of architectural documentation.
2. Concept design – preliminary layout of system elements.
3. Final design – full technical documentation.
4. Installation – physical execution of the electrical system.
5. Testing and certification – measurements, test protocols, final acceptance.

Safety and Reliability

Safety is a top priority at every stage. The design includes protective devices: RCDs, circuit breakers, surge protectors, proper earthing, and equipotential bonding. Compliance with standards guarantees safe use of the system.

System Certification

Final certification is carried out by a licensed electrician based on tests and measurements. Official reports confirm proper operation and compliance with regulations. A positive certification allows the legal use of the system.

Audits and Modernisation of Existing Installations

Modernisation improves safety and comfort, especially in older buildings. The process begins with a technical audit and an analysis of the user’s needs.

1. Modernisation project – new technical documentation.
2. Dismantling of the old system – removal of outdated elements.
3. Installation of new components – new wiring, consumer unit, fittings.
4. Testing and certification – control measurements and official acceptance.

Modernisation is an investment in safety, comfort, and property value.
