The cost of new electrical installation

If your property needs new electrical wiring or fittings, there’s no need to panic – shopping around will help you keep in budget and have things fixed to the highest standards.

Hire a professional to install new electrics

When it’s under constant pressure, electricity can be highly temperamental and cause big problems if it goes wrong. You should aim to deal with electrical problems straight away by calling in a professional engineer, who will be able to fix your electrics safely and efficiently. If, however, such breakdowns seem to be occurring on a more frequent and regular basis, your current electrical fittings may not be able to cope with the amount of work you’re trying to complete – in which case an entire refit may be your only option.

Whether you simply need extra sockets in your home, old wires and fittings in the workplace to be repaired or replaced, or more extensive re-wiring of large items of machinery, the type of electrical installation you will require will depend on a number of factors, including:

  • The power demand on the main circuit; what you will be using the electricity for and how often.
  • The type of occupancy and size of the building that needs repairs or rewiring.
  • Whereabouts in the country your property is situated and how it is affected by local and national regulations regarding new electrical installation.
  • The use of the property in terms of domestic, commercial or industrial production and how that affects the immediate environment of where the wiring and electricity must operate.

You should therefore take the time to think carefully about each of these concerns before calculating a clear budget and figure out: an estimate for the number of wires and cables that might be required; whether or not you are seeking a complete or partial refit on the property; the average temperature and humidity of the local environment where the wires will be fitted and if Government requirements or Local Authority rules will restrict or hinder any of the work or installation you need. Your final evaluation should fit neatly into one of the following three categories, whereby you can gain a rough idea of how much your electrical installation is going to cost:

  1. Household/ domestic property installation – a domestic building or typical home should have low power requirements; a dry, moderate temperature; non-corrosive and relatively safe environmental conditions and need or have little change to the overall structure (i.e. walls and ceilings) of the building on an annual basis. Electrical installation> will thus be relatively simple and can often be completed within a fortnight; the cost will depend on exactly what you want done but the rewiring of an average three-bedroom property should come in somewhere between £2,000 – £3,500, including parts and labour.
  2. Commercial/ retail property installation – a commercial or retail property may involve more refurbishment or structural changes on an annual basis and may require the use of larger and more complicated electrical appliances, such as air-conditioning or CCTV services. Depending on what the property is used for the temperature may be a little higher or cooler too, which may affect the performance of certain kinds of wiring. Once again, the cost will always vary according to the extent of the job but usually installation for a standard size retail property can come in anywhere between £3,000 and £5,000.
  3. Industrial property installation – when one thinks of industrial properties they are usually quite large and involve the use of a number of complicated electrical appliances and machinery – which might mean rather large voltage requirements. The immediate environment can also be rather temperamental, involving extreme heat, excessive wetness or a potentially explosive atmosphere. The cost of electrical rewiring or installation will depend largely here on the size of the building and what kind of insulation(thermoplastic, aluminium, steel etc.) will be required, but prices generally range from £5,000 to £12,000 for an entire overhaul.

Hiring an electrician

When hiring a contractor or a specialist firm to complete your electrical installation, make sure they are NICEIC (National Inspection Council for Electrical Installation Contracting) certified and have sufficient knowledge and experience in dealing with the particular problem you’ve got. It is a criminal offence to sell a home with faulty wiring or to hire people in a workplace where such employees may be at risk from handling electrical appliances – cutting corners here could simply leave you facing a fine of up to £5,000. To get the best deal make sure you compare at least three quotes and always check references before hiring. Once your chosen engineer gets started your newly fitted wiring and electrical outlets should enable you to live or work more efficiently and with a little extra peace of mind.
