Frequent repair bills
If an older boiler is requiring repeated repairs, it can become sensible to compare the cost of continued repairs with replacement rather than considering each fault in isolation.
Parts are becoming difficult to obtain
Availability varies by manufacturer and model. If important components are obsolete or increasingly difficult to source, future repairs may become less practical.
The boiler no longer suits the property
Extensions, extra bathrooms or changes in occupancy can alter heating and hot-water demand. A boiler that once suited the house may no longer be the best fit.
Planning replacement is better than emergency replacement
If an ageing boiler is still running but becoming unreliable, planning ahead gives more time to compare system options and installation requirements.
