Hi, Sara, I'm an NICEIC registered electrician. I'm not pitching for the work, just offering advice. You can find a NICEIC electrician on their website by postcode. There are other registration schemes, e.g. ECA, but you must use someone who is Part 'P' qualified (Domestic Installer) which means they can carry out the work, test & certify and log the job with building control. You also get insurance-backed warranty. No reflection at all on anyone else but I have lost count of the times customers discover that their 'qualified' electrician isn't and the certificate never turns up, e.g. "you wanted to pay cash so I didn't think you needed one"! For £3-4K I would be looking at a 2-3 bed house, but then I haven't seen the job. Unmodified conduit systems are usually strightforward to re-wire; problems generally occur where alterations and additions have been carried out/botched. Why does it need rewiring? (I'm not saying it doesn't given the age). If you are upgrading the fuseboard then all circuits must be in good condition before they are re-connected. Earthing and bonding will probably not meet current standards. Certainly, if you are starting to get problems and the flat is tenanted then bite the bullet and get 10 years' peace of mind.
