Well, if there was a shutoff valve (usually on the wall below the tap) you could have closed that.
Was there?

You can shut off the stop valve under the sink.
or you can shut off the valve on the water heater
or you can shut off the valve next to the PRV
or you can shut off the valve to the entire house (at the meter)
If you don't have stop valves, this is a great time to go ahead and install them now.

Amis say "faucet". Brits say "taps." Many Brit homes feature domestic hot water schemes (gravity tanks, point of use pumps, etc) that Amis know nothing about.

Ensure that you fit an isolating valve when the water is off. New installations have required them for years, but ancient ones might still be without.
Be careful if installing a valve on the output from the tank. It sounds like you have an old style gravity system. This depends on having an open to the air vent from the top of the tank. If you put a valve on there, it may explode. The valve must come after the air vent has separated off. If in doubt, just put ones near the taps.
