to be honest in my experience so long as it has all dried out and no water is trapped any where it can usually be alright.

Good old visual check dosent do any harm

Just be wary if the installation was energised for any length of time whilst wet - it plays merry hell with terminations (particularly if no RCD's present) and substantial leakage currents have been swirling around via the wet stuff.

You'll almost certainly want to be quoting for accessory changes even if the cables bell out OK

Sounds like the leak is mains water so generally thing dry out and are ok, accessories may need changing and if the insurance is already involved probably best if they are changed.
We have had a few floods in recent years which involved river water and what I have learned is that the cable companies will not confirm that the cables will be ok once submerged in river water as they cant confirm the materials deposited within the silt.
This is a good one for us honest but looking for some work sparks as when you tell the insureance Co & client that the cable manufacturers wont confirm the cables are ok, even if they test out ok its a nice strip out and rewire. all above board of course!!

Hi Goldenboy,

Big leaks, when the insurance company is involved can really show some changes in personality.

You may find that your client is asking you to condemn everything so that they may have their old wiring brought up to date by the insurance company. How you advise is your decision but have a care that you will be paid direct by the client and not be forced to wait 90 days for the insurers to pay you ( they may also make you jump through the hoops of risk assessment and so on).

I've done three of these, all of them where the client drilled through a pipe. I continue to ask myself why they were all using the mother of all drill bits and why they all let the water flow and didn't put the drill bit straight back in the hole. I'm a tad suspicious.

However, wise by then, I let the third one dry out and then ran a full I&T. Apart from having to change the DB( purely because I had reservations about leaving it in service and the wall had to be plastered anyway) and a few accessories, nothing else had to be done. They had already chosen their new down lights...

When a client spills tea or coffee into their electrics though; If they take sugar then a change will be the order of the day but if they don't then as GB says, it may dry out ok. Release the pressure on the socket fronts and let the air get in for a few days.

Kind of depends how busy you are

In a previous life I was involved with a large specialist insurance contractor and attended a couple of factory fire aftermaths . The fires weren't always the primary causes for concern for the owners but the damage and mayhem left by the fire fighters and their hoses.
Isolate the damaged fire bits, loosen all electrical face plates, covers, doors and lids, hire some blow heaters and dehumidifiers get an IR test on the mains and you will be amazed how quickly the IR rises above 1meg. From devastation to lights on in a couple of days.

Or not the options as the $pecialist are endless (milk it)

Good luck buddy
