Isolated is where the water running through the piping has been turned off. Not practical to do so in this case? It doesn't look like a complicated job but I guess it will cost £200 - £300. And if the system is old they may find other faults.
It's a job for a gas safe engineer. It is not as bad as it looks. Find yourself a local heating engineer and get a quote. If you are in no rush, get a few quotes. Has the leak been isolated.

It is recommended to replace a gas boiler after 15 years & I guess check and deal with any other issues with radiators etc.
So 40 years is getting on a bit!
My boiler is about 25 years old. At the last service the engineer told me that it is fine.
Checkatrade all promises for next week! phoned local asian hardwares, ali + 2 asians plumbers arrive within hour & job done in 1.5hrs for £250 cash - happy happy me ;)
