Introduction
Most UK homes have multiple toilets, with the average household featuring at least three facilities across main bathrooms, en-suites, and downstairs cloakrooms. With such essential fixtures in regular use, it's inevitable that toilet issues will eventually arise. When problems occur, homeowners face an important decision: repair the existing toilet or invest in a complete replacement?
This comprehensive guide will help you identify when a simple repair will suffice and when replacement becomes the more practical and cost-effective solution.
When to Choose Toilet Repair
Faulty Flushing Mechanisms
Signs to Look For:
- Multiple flushes required to clear the bowl
- Weak or incomplete flushing
- Flushing stops midway through the cycle
Common Causes:
- Low water level in the cistern
- Prematurely closing flapper valve
- Partial blockage in the trap or drain
- Malfunctioning flush valve
Typical UK Cost Range:
£80-£150 for most flushing mechanism repairs, including parts and labour.
Refill Problems
Signs to Look For:
- Cistern doesn't refill after flushing
- Water continuously runs into the bowl
- Refill is extremely slow or stops before completion
Common Causes:
- Damaged or malfunctioning fill valve
- Issues with the float mechanism
- Leaking flapper valve
- Damaged overflow tube
Typical UK Cost Range:
£70-£120 for cistern component replacement.
Minor Leaks at the Base
Signs to Look For:
- Small amounts of water around the toilet base
- Dampness when mopping near the toilet
- Slight odour near the fixture
Common Causes:
- Worn wax ring seal
- Loose mounting bolts
- Hairline crack in the porcelain (if minor)
Typical UK Cost Range:
£90-£180 for resealing and securing, depending on accessibility.
When to Invest in Toilet Replacement
Persistent Clogging Issues
Signs to Look For:
- Frequent blockages despite proper use
- Plunging required multiple times per week
- Professional drain cleaning provides only temporary relief
Typical UK Cost Range:
£250-£600 for a new toilet installation, including removal of the old unit (excluding the cost of premium fixtures).
Structural Instability
Signs to Look For:
- Toilet rocks or shifts when in use
- Tightening mounting bolts doesn't resolve wobbling
- Visible cracks in the porcelain base
Typical UK Cost Range:
£300-£700, potentially more if subfloor repairs are needed.
Age and Inefficiency
Signs to Look For:
- Toilet is over 15-20 years old
- Excessive water usage (older models use 9-13 litres per flush)
- Frequent repairs needed
Typical UK Cost Range:
£280-£650 for standard efficient models; £600-£1,200 for premium water-saving or smart toilets.
Extensive Cracking
Signs to Look For:
- Visible cracks in the bowl or tank
- Small leaks that worsen over time
- Rough surfaces that are difficult to clean
Typical UK Cost Range:
£250-£550 for standard replacement models.
Making the Right Decision: Repair or Replace?
Cost Analysis
- If repair costs exceed 50% of a new toilet's price, replacement is usually more economical in the long run.
- Factor in potential water savings from newer, more efficient models.
Age Consideration
- Toilets older than 15-20 years are prime candidates for replacement, even if the current issue could be repaired.
- Newer fixtures (less than 5 years old) typically warrant repair unless structural damage has occurred.
Environmental Impact
- Replacing an old, inefficient toilet with a modern low-flush model can save thousands of litres of water annually.
- Many water companies offer rebates for upgrading to water-efficient models.
