My circuit board is about 10 years old. Does it need replacing? Been told by a electrician it needs updating is this true to bring it up to date with new regulations?
Depending on the condition, but it is better to replace
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
It's your choice to update it, as for your own safety its ideal you should update it, you not doing anything illegal but technology is changed and adding new gadgets everyday in your house may put strain on your old CU.
Not necessarily, if it has RCDs covering all circuits and is in good condition it is fine technically. However if you need electrical work carried out the electrician will need to confirm on the certificate that the box is compliant with fire safety this can be achieved by putting a metal enclosure over it but this may be more expensive than changing the box.
