The internet and local papers are filled with plumbers offering services for everything from quick repairs to full heating system installations. But with so many options available, how do you choose the right one—especially when the comfort of your home and family depends on the quality of their work?
A few minutes spent on a trade directory or local website will yield dozens of potential candidates. But that doesn’t mean you should go with the first name you see. Taking the time to choose the right professional can save you stress, delays, and costly mistakes later down the line.
1. Understand the Difference Between a Plumber and a Plumbing Contractor
If you need something straightforward—like swapping out a radiator or fixing a minor leak—a qualified individual plumber is usually sufficient. However, for more complex jobs such as installing cast iron radiators in multiple rooms, setting up waste systems, or designing heating for an entire building, you may need a plumbing contractor or specialist firm with broader resources and experience.
Before hiring, be clear on the scale of your project and choose someone equipped to handle it properly.
2. Look for Relevant Experience
Always ask about the plumber’s experience, especially with similar work. Some plumbers focus on new-build installations; others are more suited to repairs and renovations. If you're working with traditional materials like cast iron radiators, look for someone who has worked with these systems before. They’ll understand the weight, fittings, and correct handling techniques to ensure your radiators perform and last for generations.
3. Check Credentials and Insurance
Always verify that your plumber is qualified and fully insured. For gas-related work, they must be Gas Safe registered. For general plumbing, membership in bodies like CIPHE is a positive sign. Public liability insurance is essential—especially for larger projects—so that you’re protected in the unlikely event of an accident or damage.
4. Residential or Commercial Experience?
Plumbers often specialise in either domestic or commercial systems. Commercial plumbers may carry higher costs and qualifications you don’t need for a home job—so make sure the professional is aligned with your property type and budget.
5. Ask the Right Questions
Don’t be afraid to ask practical questions like:
-
How do you handle emergencies?
-
Will you provide a written quote?
-
What warranty or guarantee do you offer?
-
Can I see examples of past work?
A good plumber will be transparent, clear in communication, and happy to provide references or photos of previous jobs.
6. Get Quotes—but Don’t Just Go for the Cheapest
For larger projects, get a few quotes so you can compare not only prices but professionalism and responsiveness. Be cautious of quotes that seem too good to be true—especially those offering a "cash deal." These often come without paperwork or a clear scope of work, which can leave you exposed if something goes wrong later.
Tip: Always insist on a written invoice detailing what was done, when, and for how much. This creates a clear paper trail for future support or guarantees.
7. Prioritise Quality Over Cost
Choosing the cheapest option can end up being the most expensive in the long run. Poor installation—especially with heavy cast iron radiators—can lead to leaks, inefficiencies, and expensive damage. High-quality workmanship ensures your radiators look and perform beautifully for decades.
