They also handle routine maintenance and repairs including radiator servicing, leak detection and resolution, plus appliance connections for dishwashers and washing machines.

What distinguishes John Clay Plumbing & Heating is the owner's extensive qualifications and professional credentials. John holds dual qualifications as both a qualified plumber and engineer, carries OFTEC registration (C4419) for oil boiler work, holds certification for unvented cylinder installation, and is an accredited heat pump installer. This rare combination of certifications means the business can legitimately handle everything from conventional heating systems to cutting-edge heat pump technology in one place.

The business emphasises flexibility and a customer-focused approach, building long-standing relationships through reliable service and technical expertise.
