Frequently Asked Questions

Check the following before calling a professional:

• 1. Ensure the boiler is switched on.
• 2. Check that the thermostat is set correctly.
• 3. Make sure the pressure gauge is within the recommended range (usually 1–2 bar).

If these are fine and there’s still no hot water, give our friendly team a call and we'll do our best to help assist you!

To release trapped air and improve heating efficiency:

• 1. Turn off your heating system and allow radiators to cool.
• 2. Use a radiator key to slowly open the bleed valve at the top of the radiator.
• 3. Wait until water (not air) starts to escape, then close the valve.

If you'd like a more in depth explanation, read our blog here.

Low boiler pressure can be caused by:

• 1. A small leak in the system.
• 2. Recently bled radiators.
• 3. Water loss from the system.

You can re-pressurise the boiler using the filling loop according to the manufacturer’s instructions. If the pressure keeps dropping, call give our team a call.

Follow these steps:

• 1. Turn off all gas appliances.
• 2. Contact your gas supplier to arrange a refill.
• 3. Once the supply is restored, follow your boiler’s instructions for restarting.

Never attempt to reconnect the gas supply yourself.

This usually indicates trapped air in the radiator. Bleeding the radiator will often solve this issue. Read our blog on how to this here

Boilers should be serviced annually. Signs that a service may be needed include:

• 1. Unusual noises coming from the boiler.
• 2. Frequent pressure drops.
• 3. Slow heating of radiators or hot water.
• 4. Error codes on the boiler display.

Banging, gurgling, or whistling sounds can be caused by:

• 1. Air in the system.
• 2. Limescale build-up.
• 3. Water flow issues.

Bleeding radiators and checking the system pressure can help, but persistent noise should be checked by a professional.

Steps to handle leaking taps:

• 1. Turn off the water supply to the affected tap.
• 2. Inspect washers or cartridges for wear and replace if needed.
• 3. If unsure, call a plumber to prevent water damage.

Tips to prevent freezing pipes:

• 1. Insulate exposed pipes during winter.
• 2. Keep your home heated even when away.
• 3. Let taps drip during extreme cold.

Low water pressure can result from:

• 1. Blockages in pipes.
• 2. Leaks in the system.
• 3. Issues with the mains supply.

Check for leaks and clean faucet aerators. Persistent problems may need a plumber to inspect your system.

Yes, if your boiler is cold, you can top it up using the filling loop:

• 1. Follow your boiler’s manual carefully.
• 2. Never exceed the recommended pressure.
• 3. If unsure, contact an engineer.

Keep your system running efficiently by:

• 1. Regular servicing.
• 2. Bleeding radiators when needed.
• 3. Monitoring boiler pressure.
• 4. Checking for leaks.

Annual maintenance from a Gas Safe engineer is strongly recommended.

Refer to your boiler manual for the meaning of the code. Some codes may require a reset, but others indicate a fault needing a Gas Safe engineer’s attention.

Possible reasons include:

• 1. Air in radiators.
• 2. Low boiler pressure.
• 3. Limescale build-up.
• 4. Underperforming pump.

Bleeding radiators and checking pressure can often help, but persistent delays may need professional inspection.
