Every emergency callout has the same shape. Something has failed, it is the
wrong time of night, and the first decision you make is who to let into your
home. That decision is worth more than the repair.
Do the free checks first
Almost every one of these problems has steps you can take yourself, before
anyone travels, that either fix it or make the repair cheaper.
- A burst pipe or a leak. Turn the water off, drain the system, protect the
boiler and the heating — then decide who to ring. The first five minutes are
worth thousands. See
burst pipe at 3am.
- Lights out, or a trip switch that keeps going. Check whether it is just
you or the whole street, then go and look at the consumer unit, then find the
appliance causing it. There is also a legal line on what you may not do
yourself. See
what to check before calling an electrician.
- No heating or hot water. Four free checks, in order. If you rent, the
standard your landlord must meet is stronger than most tenants think, and
there is a free entitlement almost nobody claims. See
no heating or hot water.
Checking who you are calling
This is the part that matters, and it takes about two minutes.
Gas is the exception that is not optional. Anyone working on gas in the UK
must be Gas Safe registered. That is the law, not a preference, and the register
is public and checkable in seconds. If someone is not on it, the conversation is
over.
For electrics, plumbing and water, and general trades, there are competent-person
schemes and trade registers that can be checked at the source rather than
trusted from a logo on a van. Locksmiths are the unregulated one — no
licence exists at all, which is why they get their own treatment on our
sister site, where
every guide is about the one trade with
no regulator behind it.
The registers for each trade, the universal checks that apply whatever the
trade, and what to do if it goes wrong afterwards, are in
how to check any UK tradesperson in two minutes.
Do this now, not at 3am
The single highest-value ten minutes on this whole site: find your stopcock,
find your consumer unit, and save one checked number for a plumber and one for
an electrician. All three are trivial on a Tuesday afternoon and close to
impossible while water is coming through a ceiling.
We refer to registers, not to firms
We name no trades.
Every route here points at the official register — Gas Safe, the electrical
competent-person schemes, WaterSafe, TrustMark — because a register you can
check yourself is worth more than a recommendation from a page with something to
gain.
The essential numbers are collected on
emergency numbers and essential services.
