Many plumbing firms are part of the Chartered Institute of Plumbing and Heating Engineering, and membership director Tim Sainty said that firms can often have order books full for months ahead.
Mr Sainty said: “Needing an emergency plumber is a stressful time for any household.
“Our members work to a code of professional standards which makes it clear that the public can be confident they will be employing someone with the necessary skills and commitment to high standards.
“This ranges from being available to deliver services when required, through to ensuring that those in attendance will hold the appropriate technical skills.
“Although it’s not always possible, prevention is almost always a better approach than cure.
“Most plumbing and heating engineers are in very high demand.
“So consumers should try to schedule necessary work in advance rather than when emergency strikes.”
