As a last resort, is there a stop-cock outside the house? (on the pavement, for example).
In my experience, if that doesn't stop the water, nothing will.

If it is a traditional system it will have a cold water "rising main" which normally feeds the kitchen cold tap (potable water) and a header tank in the attic, or high up in the top floor. The header tank feeds everything else and until it is fully drained (Normally about 10-15 gallons in old money) the system will still have water in it. Read the instructions carefully before fitting your new tap.

There is a reasonably good DIY guide here: http://www.diyfixit.co.uk/plumbing/

For replacing taps under the rim of a bath or sink you may find you need a specialist tool called a shetack wrench. Quite cheap from a plumbing supplier or DIY shop.Take your time and have fun!

No tanks, it's a combi boiler, and it was a hot water tap.

The new stop cock is about 18" from the kitchen taps, and they were still going strong after about five minutes.
ou can turn the valve off under the boiler for the hot water

cold should turn off from the stop valve, are you turning it clockwise?

good post but unlikely to have a cold water cistern if they have a combi boiler, normally all direct feed

My house doesn't have a stop cock, just a series of service valves. Some people shouldn't be allowed to do DIY as they just do something that kind of does the job (scotch block connector for mains electric anyone?)

I always try to do something that anyone else following me will look at and think "ah, right, that's helpful"

(please note, the stop cock and service valves issue in my house is not a result of my work.)

are you sure you have no stop valve? service valves are good for local isolation but not sufficient for a full isolation
