Which Boiler Brand Offers the Best Warranty?
Purchasing a new boiler is a real investment into both your home and your family’s comfort and health. Making the right choice for your home will come down to several factors such as efficiency, size and price, but something else that should be high on your list to compare is the manufacturer’s warranty.
Generally speaking, a warranty means that in the event that your boiler develops a fault or breaks down, the manufacturer will send an engineer to fix or replace your boiler at no extra cost. As a general rule, the longer the warranty the higher the quality of the boiler. Of course, this usually means a higher cost too. However, in times of emergency, a comprehensive warranty can be invaluable!
Manufacturers rarely offer a blanket warranty across all their products. They will usually vary range by range. A typical boiler warranty will cover between 1 – 10 years. So which manufacturers offer the best warranties and will give you real peace of mind?

What is a boiler warranty?
A boiler warranty (sometimes called a guarantee) is an agreement between the homeowner and the manufacturer of the boiler. In the event that your boiler develops a fault, the manufacturer will send an engineer to repair the problem or replace the boiler. This agreement lasts for as long as the stated warranty period which is usually anything from 1 – 10 years. In theory, the longer the warranty the more confidence the manufacturer has that their boiler will stand the test of time.
When it comes to boilers most will include a 1 year warranty as standard. However, many manufacturers give you the opportunity to extend this period considerably by either paying extra or simply by meeting certain installation and maintenance standards. Note: Even purchased warranties may be invalidated if these standards aren’t met.
Terms and Conditions
Each and every manufacturer warranty will be dependant on you meeting certain terms and conditions. In order to keep the warranty valid for the full period it’s important you get to grips with what’s expected of you as the homeowner and what is protected by the warranty, right down to the smallest fineprint. For example, some warranties only apply to certain parts of the boiler like the heat exchanger and may or may not include labour costs.
Common terms and conditions include:
- The boiler needs to be installed by a Gas Safe registered engineer.
- The boiler must be registered with the manufacturer within 30 days of installation. It’s best if this is done by your engineer. This is a really important but often overlooked detail. However, don’t assume the engineer has taken care of it; it’s always worth checking a couple of weeks later to make sure it has been done.
- Manufacturers may also specify that your existing heating system is flushed through to clear any debris or dirt left so your new boiler is starting with a “clean slate”.
- Annual servicing is also a common requirement and they can stipulate that this must be carried out by one of their engineers or an accredited partner installer. Keep hold of all your service records for this reason.
- All repairs must be carried out using only manufacturer approved parts.
A quick word about boiler insurance…
Boiler insurance, or emergency boiler cover, may be suggested to you as an essential purchase. When you take out insurance on your boiler or heating system, you pay a monthly premium as you would with home or car insurance and, in the event your boiler breaks down, an engineer will fix it at no extra cost.
While this sounds like a sensible plan, the reality is that two thirds of homeowners who take out this cover never actually make a claim*. Those who do usually end up paying more in monthly premiums than they would to find and hire their own engineer to fix the problem. In addition, as most boilers include a manufacturer’s warranty, the insurance can be a completely unnecessary expense.
