    Turned the hall way light on this morning and it blew the main fuse and the fuse the lights are on. Switched them back on but none of the lights in the house will come on.
    Any ideas?

    The timer that controls the heating and hot water has stopped working. It's stuck on the time when the lights blew this morning.

    I take that when you say fuses you mean an RCD trip? In which case maybe you've missed one that still needs to be reset. One all I've seen up is on rather than down.

    Have you removed the blown bulb?

    Circuits these days are split usually. IE you have two banks of switches. You then have a master switch on the two banks. Individual switches can trip, but take the master switch with it.

    Sounds like that has happened.

    The white box I have switched back/reset but the old looking black one I have never seen before.
    The bulb that blew has been removed.

    On the black one, the white one on the left is a circuit breaker, the rest of wired fuses. Not sure why you have two - is the new one an extension?

    Pull the wired ones out and check the wires are intact. A bulb blowing can often cause a fuse to break.

    Turn off the main black switch first though.

    Be aware that you may need some fuse wire to replace the broken one - or replace with a circuit breaker - make sure it is the same wattage as the fuse. If replacing with a circuit breaker, take the old one with you to get the same type. Make sure you don't turn off freezers though.

    If it's wired up correctly it should be:

    5 amp, White: Lighting / small plug circuits

    15 amp, Blue: Immersion/storage heaters

    30 amp, Red: Ring circuits (sockets), cookers, showers, radial circuits

    If you pull them out and there are cartridge fuses, the following applies:

    5 amp,White: Lighting / small plug circuits
    15 amp, Blue: Immersion/storage heaters
    20 amp, Yellow: Smaller radial circuits / water heaters
    30 amp, Red: Ring circuits (sockets), cookers, showers, radial circuits
    45 amp, Green: Cookers/showers

    As Blue Max said, the black box is an old style physical fuse box which would normally be replaced by the white consumer unit, so I don't know why you have both either. The physical fuse blocks can be replaced with RCD breakers which is what has happened with the one on the left. That should be in the up position, same as the switches on the white box.

    If that is up then turn off the switch on the black box (in this case off is up!) & pull the blocks out one at a time. You should be able to see the fuse wire running between the terminals. It will be obvious if it's broken.

    If you locate the lighting circuit on your consumer unit, try switching the mcb on and off a few times. It can be a common occurrence that the mechanical switch can stick if they are not tested regularly.
