You may need an EICR conducted if you own a property or premises that has an electrical installation - which most do. Although landlords and employers HAVE to have an EICR, we would argue everyone should have an EICR at regular intervals to keep on the safe side of BS7671, the electricity at work Act, and, of course, HSE (who carry a big hammer of the law and can swing it very hard).
The only real way of telling whether your electrics are completely safe is by having a thorough health check on the electrics (EICR) carried out by an experienced electrician. We specialise in these - please find out more here.
