Insulate all exposed pipes in your loft, garage and exterior walls with foam lagging — available for under £10 from any DIY shop. Keep your heating on a low background temperature (at least 12°C) even when you are out, and open loft hatches occasionally to let warm air circulate. If you are leaving the property empty in winter, consider draining the system or asking a neighbour to check daily.

Stop flushing immediately and turn off the water supply to the toilet — there is usually an isolation valve on the pipe behind or beneath the cistern. If water is flooding the floor, lay down towels and open windows for ventilation. Avoid using chemical drain cleaners as they can damage your pipes and are hazardous. Call an emergency plumber if the blockage does not clear with a plunger.

Yes, leaking radiators are a common plumbing repair. The leak is usually from the valve, the bleed point or a corroded joint. A plumber can typically fix a leaking radiator valve in under an hour for £60 to £120. If the radiator body itself is corroded through, it will need replacing — expect £150 to £350 including the cost of a new radiator.

Repairing a burst pipe in Cardiff generally costs between £150 and £400, depending on where the pipe is located and how accessible it is. If the burst has caused water damage to walls or flooring, the overall cost will increase. Turn off your stopcock immediately to limit damage while you wait for the plumber to arrive.

Check that the plumber holds relevant trade qualifications such as NVQ Level 2 or 3 in Plumbing. If they are working on gas appliances, they must by law be Gas Safe registered — ask for their registration number and verify it on the Gas Safe website. Membership of trade bodies like the Chartered Institute of Plumbing and Heating Engineering (CIPHE) is a further mark of competence.

Drain unblocking in Cardiff typically costs £80 to £200 for a standard blockage. More stubborn blockages requiring high-pressure jetting may cost £150 to £300. If a CCTV survey is needed to locate the problem, expect an additional £100 to £250.
