Boiler broken down? What to do right now
A few steps can keep you safe and help the engineer fix the fault faster.
Smell gas? Leave, ventilate, and call the National Gas Emergency line first
If you smell gas, this comes before everything else. Leave the property, open windows on your way out if it is safe, do not use switches or naked flames, and call the National Gas Emergency Service on 0800 111 999. Only arrange a repair once the supply has been made safe.
Leaking boiler — turn off the boiler and water supply
If your boiler is leaking water, switch it off at its controls and turn off the water supply to it. Place a container under the leak and keep the area clear. A leaking boiler should be looked at by a Gas Safe engineer.
No heating or hot water — quick checks
Check the boiler’s pressure gauge; if it has dropped below around 1 bar, low pressure may be the cause. Check the thermostat is calling for heat and the programmer is set correctly. If your boiler has a reset button and is showing a fault, one reset is fine, but do not keep resetting it repeatedly.
Note your fault or lockout code to speed up the repair
Most modern boilers show a fault or lockout code on the display when something goes wrong. Note it down and give it to the engineer when you request a callback. It often helps them arrive with the right part.
How fast can an emergency boiler engineer reach me?
Where a Gas Safe engineer is available locally, call-outs can be as fast as 30 to 60 minutes. Response times depend on your location, the time of day and how many engineers are free nearby, so it varies, but our network is built for speed.
Because we cover 24/7, 365 days a year, you can request a callback at any hour, including overnight, at weekends and on bank holidays. In cold snaps, breakdowns affecting vulnerable occupants are treated as priority, and the engineers who respond will give you a realistic arrival time with their fee.
Emergency boiler repair costs — clear and upfront
No one wants a vague figure on the phone and a bigger bill on the doorstep. With us, you see the call-out fee before you commit and compare it across engineers.
What a call-out or diagnostic fee covers (parts on top)
An emergency call-out usually covers the engineer reaching you and diagnosing the fault. Any parts and further labour are quoted on top, and a good engineer confirms the parts cost before fitting them. Emergency boiler repair call-out and diagnostic fees in the UK typically start from around £80 to £150, with out-of-hours rates usually higher.
Repair vs replace — when a new boiler is the better call
Repair is usually the quickest, cheapest fix on a boiler under roughly 8 to 10 years old. If yours is older, breaks down repeatedly, or the repair cost approaches the price of a new unit, replacement often works out cheaper over time. Before you decide, see our new boiler cost guide to compare prices, or use our plumbing and heating hub for a service or planned replacement.
