Good to know

Common questions

General guidance about plumbers in the UK, not specific to any one business.

Do I need to turn off my water if there's a leak?

Yes. Locate the stopcock, usually under the sink or in a cabinet near the front door, and turn it clockwise to stop water flow. This prevents damage while waiting for help and limits water waste and costs.

How often should a boiler be serviced?

An annual service is recommended to maintain efficiency, safety and performance. Regular servicing identifies wear and corrosion early, extends boiler life, and helps spot issues before they cause breakdowns in winter.

What causes blocked drains?

Hair, soap scum, grease and food debris build up inside pipes over time. Wet wipes and sanitary products don't dissolve and cause blockages. Tree roots can penetrate old pipes. Regular flushing with hot water helps prevent accumulation.

Why is my radiator cold at the bottom?

Sludge and corrosion debris settles in the bottom of radiators, stopping hot water from circulating. The radiator needs bleeding or flushing to remove trapped air or sludge. A full system flush clears debris from all radiators and pipes.

Can I fix a leaking tap myself?

Simple cartridge or washers can be replaced by householders with basic tools. However, identifying the fault type correctly takes experience. If unsure, a tradesperson diagnoses the cause and fits the right replacement part correctly.

What's the difference between a plumber and a heating engineer?

A plumber handles water supply, drainage and general pipework. A heating engineer specializes in boilers and central heating systems. Many tradespeople do both. Gas boiler work legally requires Gas Safe registration in the UK.
