If your boiler completely breaks down, you’ll know about it – and fast because you won’t have access to hot water or heating. But before it stops working entirely, there are some tell-tale signs you can look out for that might indicate you need a new boiler.
General guidance suggests that boilers over 10 years old should be replaced. Boiler technology evolves, making older models less efficient, less effective, and potentially not as safe as newer boilers.
If you’re constantly calling out a boiler engineer to check what’s wrong with your heating or hot water, your boiler might be at the point it needs replacing. Paying for replacement parts and call out charges for quick fixes mounts up; invest in a new boiler instead.
However, unlike most plumbing companies, Metro Plumb do not charge a call-out fee.
With pressurised heating systems, small leaks in the system will cause the system pressure to drop. Pressure relief safety valves can also release water from the system. But if neither of these are the cause of pressure drops, you’ll need to have your boiler assessed.
Any banging, gurgling, and kettling noises from your boiler or radiators indicate something is wrong. Call an engineer to see if it can be rectified, but if not, and your boiler is very old it may be time to purchase a new one.
One of the reasons older boilers should be replaced is their energy credentials. Boilers are rated A to G, with A-rated systems the most energy-efficient. Less efficient boilers will cost you extra money in heating bills, so replacing your inefficient boiler with a newer A-rated version could save you between £45 and £300 a year on your heating bill.

A healthy boiler flame should be bright blue. If it’s burning yellow, it’s a sign that the combustion of the gasses is incorrect which could cause a carbon monoxide problem. Carbon monoxide is dangerous – it’s colourless and odourless and could be fatal to the people in your home if exposure levels are high; symptoms of carbon monoxide poisoning include fatigue, nausea, headache, and dizziness.
If your boiler needs replacements, but it’s difficult to find the parts, it’s a sign the boiler is no longer fit for purpose. Rather than paying out over the odds for hard-to-find parts, it would pay dividends to invest in a new boiler.
If your house never feels warm enough, if the heating takes ages to reach the selected temperature, or you’re always running out of hot water, it could be time to replace your boiler. Call out your heating engineer and have them diagnose what your next steps should be.
