If you notice your radiators are hot at the top but cold at the bottom, or need to bleed your radiators more often, then you may have sludge built up in your system.
A safe level for your boiler pressure should be between 1.0 and 2.0 bar. Watch this video to learn how.

The Boiler Upgrade Scheme is a Government grant of £7,500 to support with the upfront costs of installing low carbon heating systems, such as an air source heat pump, subject to eligibility. A temporary uplift of £1,500 was also introduced in July 2026 to provide additional support for off-grid property owners.
