​At HSI Electrical Edinburgh we provide a comprehensive rewiring service. The rewires carried out at hsi comply to all safety and building regulation requirements.

If rescuing your wiring is not possible a full rewire may be necessary. This will be carried out with the minimum of disruption, by a company that specialises in this area. There are many ways to wire a property or shop and we will discuss what you want to achieve, before designing your new electrical installation. We understand budget is important and can offer options to suit, whilst still ensuring a fully comprehensive rewire, complete with certification. We will design your system with a fixed quote, however, we also offer a ‘price per point’ system should you wish to add an extra socket or anything else throughout the installation. 
All rewires are designed with the future in mind. We leave plenty of room in your new Consumer Unit to add additional circuits, e.g. solar system installations. Furthermore, a thorough test of your incoming supply will be carried out before any work commences. In addition, we also provide a detailed systematic plan that will allow you to follow our progress, so you can gauge when the work will be finished. On completion, plastering work, ethical recycling and rubbish removal of waste material are carried out and you will receive a 1-10 year guarantee in accordance with your chosen wiring option.

SAFETY AND SAFETY UPGRADES
If your consumer unit (fuse board) is dated and does not have RCD protection (http://en.wikipedia.org/wiki/Residual-current_device) then it is likely you are due for a rewire or upgrade, depending on the condition of your current installation. 25 years is the recommended length of time between rewiring, however, if you have a certain type of wiring that has been installed well in the first place and looked after in non corrosive condition, then it is possible we can carry out an upgrade. This involves a full test on your wiring (similar to a pre-MOT) to determine there are no current faults or degradation. The test will also flag any wiring needing attention. 

Firstly, we test your Scottish Power supply and the main Earth. Irrespective of who supplies your electricity, it is Scottish Power’s responsibility to upgrade any supplies not to standard. In new builds Scottish Power must provide an Earth, but in the past Earthing was not their responsibility and the Earth used to be tapped from the water or gas supply. In recent years, however, the water and gas supplies have been getting replaced, from metal to plastic, and homes have been losing their existing Earth. The utilities companies do post leaflets through doors, but these warnings are not always received. This is why I am happy to provide a FREE initial consultation to determine where you stand. Once the Earth issue has been resolved, the upgrade is a full days’ work and includes a Consumer Unit upgrade and hard-wired smoke alarms. These will be designed to meet the differing needs of each house and in accordance with electrical and building standards, and manufacturers’ recommendations in accordance with BS5839. An earth upgrade may be required, that links your gas and water supplies to your new RCD protected Consumer Unit. In the event of your pipe-work becoming live through a fault, the Consumer Unit RCD will trip, preventing shock to the consumer. 
​
Finally, looking at your sockets and switches, I may recommend they get changed, as faulty or old switches can cause the electricity to arc, thus becoming a fire hazard. Once we have upgraded as necessary, we will issue certification and as an approved electrician, your installation would be recognised by any authority as having been designed and installed correctly.
