Typical ranges: cylinder: £500–£1,500. Installation: £500–£3,000+. Depends on size, brand, and system complexity.

Check the basics first: power supply, thermostat settings, pressure gauge, and whether the gas. Electric supply is on. If everything looks fine, contact a qualified heating engineer.

Common causes include low pressure, frozen condensate pipe, power cut, faulty thermostat, or internal component failure.

Low pressure usually means there’s not enough water in the system. It often needs repressurising using the filling loop.

A lockout is a safety feature that shuts the boiler down when it detects a fault, such as no flame, pressure issues, or blocked components.

You can check simple issues like pressure and power, but internal repairs should always be done by a Gas Safe registered engineer.

Banging, whistling, or gurgling may indicate air in the system, limescale build up, or low water pressure.

Boiler pressure. Thermostat settings. Electricity and gas supply. Any error codes on the display. Frozen condensate pipe (in cold weather).

Simple fixes may take under an hour. More complex faults or parts replacement can take longer if parts need ordering.
