From urgent plumbing faults to boiler, heating and gas-related problems, we’ll help you identify the right type of engineer for the issue you’re experiencing.

Not every fault needs an immediate emergency call-out. Use the guide below to understand how quickly the problem may need attention.
Some smaller plumbing and heating issues can usually be booked for a convenient appointment rather than treated as an emergency.
Keep an eye on the problem and arrange a repair before it becomes more disruptive.
Some faults are not immediately dangerous but should be investigated quickly before they worsen or leave essential services unavailable.
Arrange an engineer visit as soon as possible so the cause can be identified and repaired.
Problems that risk flooding, significant property damage or immediate safety concerns should be dealt with as a priority.
Make the area safe where possible and seek the appropriate emergency or professional support immediately.
Tell our team what is happening and we can help you understand the appropriate next step.
A few simple precautions can help limit damage and keep the situation under control while you wait for professional help. What you should do depends on the type of problem affecting your property.
If water is escaping from pipework, turn off the water supply where it is safe and practical to do so. Move belongings away from the affected area and use containers or towels to help contain smaller amounts of water.
Avoid touching electrical sockets, appliances or wiring that may have been affected by water.
Look at the boiler display for any warning or fault code and check whether the thermostat or heating controls have changed. This information can help the engineer understand what has happened.
Do not remove the boiler casing or repeatedly reset a fault that continues to return.
Stop flushing the toilet and avoid using it until the fault has been investigated. If you know how to safely isolate its water supply, doing so may help prevent additional water entering the toilet.
Keep the surrounding area clear and contain any escaped water where possible.
If you believe there may be a gas-safety issue, do not attempt to dismantle or repair the appliance yourself. A suspected gas leak should be treated as a safety emergency rather than a normal repair.
Follow the appropriate official emergency gas-safety procedure if you suspect a leak or immediate danger.
We can ask a few questions about the problem and help you understand the safest practical next step.

If it is safe to do so, take practical steps to limit further damage, such as isolating the water supply during a major leak. Avoid dismantling boilers, gas appliances or electrical equipment yourself. Tell our team what you can see and what has changed.
Yes. Sudden boiler shutdowns can be caused by a range of faults, including pressure problems, ignition issues, controls or component failures. An engineer can investigate the cause and explain the appropriate repair.
Check whether the problem affects the whole property and whether the boiler is displaying a fault code. Loss of heating or hot water may be caused by the boiler, controls or wider heating system and should be investigated if the problem continues.
Common parts and fittings may be carried on service vehicles to help complete more repairs during the first visit. If a specific part is required, the engineer will explain what is needed and the next step.
Gas-related work should be carried out by appropriately qualified Gas Safe registered engineers. Our team can help arrange the right engineer where a boiler or gas-related fault requires professional investigation.
