Bangor& Surrounding Area

CORGI was the old gas safety registration body in the UK, replaced by the Gas Safe Register in 2009. Any engineer still claiming to be CORGI registered is either out of date or misleading you. The Gas Safe Register is now the only legally recognised body for gas work in the UK. Always check the Gas Safe Register website to verify your engineer's credentials.

Boiler repairs in Bangor typically cost between £150 and £400, depending on the fault and the parts required. Common repairs like replacing a faulty diverter valve or fan motor sit at the lower end, while PCB (printed circuit board) replacements can push costs higher. A Gas Safe registered engineer will diagnose the fault and provide a fixed quote before starting any work.

Boiler error codes vary by manufacturer but typically indicate a specific fault — low pressure, ignition failure, fan fault, or overheating. Check your boiler manual or search for your boiler make and model plus the error code online. Some codes like low pressure (often E119 or F1) can be fixed yourself by repressurising, while others such as ignition lockout require a Gas Safe registered engineer.

A combi boiler heats water on demand and is ideal for smaller homes with one bathroom — no tank or cylinder needed. A system boiler uses a hot water cylinder and suits homes with two or more bathrooms where demand is higher. Conventional (regular) boilers have both a cylinder and header tanks and are found in older properties. Your engineer will recommend the right type based on your home's size and hot water demand.

A leaking boiler should always be taken seriously. While a small drip from a pressure relief valve may indicate a minor issue, water leaking from the boiler casing can damage internal electrics and create a safety hazard. Turn off the boiler and the water supply to it, place a container under the leak, and call a Gas Safe registered engineer. Never attempt to repair a boiler leak yourself.

If you smell gas, do not touch any electrical switches, do not light any flames, and open all windows and doors immediately. Turn off the gas supply at the meter using the emergency control valve — turn the handle so it sits across the pipe. Leave the property and call the National Gas Emergency Service on 0800 111 999 from outside. Do not re-enter until given the all-clear.
