How often does a boiler need to be replaced?

A boiler is a key component of your home - if something goes wrong with it you may be left without heating and hot water, which can be a real nightmare.

Unfortunately, this always seems to happen when you least expect it, leaving you wishing you’d replaced it when it was still hanging in there. Here's some advice about how long the average boiler should last and how often you should replace the boiler in your home.

How long is a boiler supposed to last?

A good boiler should last up to 10-15 years with minimal issues, as long as you do what you should to keep it in good working condition. This starts from as soon as you receive your new boiler, which should be installed by a Gas Safe registered engineer.

A new boiler should be, at most, a once-in-a-decade investment, so you’ll want to make sure you're getting it right from day one. At ImpraGas, we offer a professional boiler installation service that ensures your boiler is installed to the highest standard. Our installations and inspections are only ever carried out by Gas Safe registered engineers who know exactly how to get the job done.

How often should I get my boiler serviced?

To make sure your boiler keeps performing well, it's vital to have your boiler serviced once a year. This annual servicing ensures that your boiler will run efficiently all year ‘round. Also, an annual service will often be a condition of your insurance policy and your boiler warranty agreement. 

 We offer a 10-year service plan with the boilers we install, which means that in the unlikely event of a breakdown, the manufacturer of your appliance will be out to assist you within 24 hours, at no extra cost! This is to ensure that your boiler lasts for its intended lifespan, if not longer.

An annual boiler service is a very important part of boiler maintenance, especially if you want your boiler to last for a long time and ultimately save you money. 

Regular boiler services also ensure the safety of your household, as any blockages or leaks could be incredibly dangerous if left unattended. 

But what actually happens during a boiler service? 

A standard boiler service involves a series of checks that are performed by a qualified engineer who should be Gas Safe registered. If you're unsure whether your appointed engineer is Gas Safe, ask to see their Gas Safe ID prior to the inspection. Once you are happy to proceed, here are the following steps which should be included in your boiler service. 

Annual boiler services typically include:

  • Overall Inspection 

Your Gas Safe registered engineer should check your boiler to assess its overall condition. This includes checking the controls, checking for leaks, and looking for any clear visual faults.

  • Boiler Casing Removal 

Your boiler casing should be removed to ensure that everything is clean and running smoothly inside your boiler. The CO and combustion ratio to ensure they are running safety and not emitting too much carbon monoxide gas.

  • Gas Pressure Test 

This check tests the pressure from your boiler and assesses whether it is at the right level. A loss in gas pressure could stop your boiler working. 

  • Flue Check 

A flue check involves checking the flue is properly fitted and it is not blocked by any obstructions. It is vital your flue is not obstructed in any way, as this could lead to carbon monoxide poisoning. 

  • Switched-On Boiler Check 

Your boiler service engineer may also check how your boiler functions when it is turned on. They may also tidy up or check your boiler for any limescale or debris during the boiler service.
