A boiler is one of those household appliances that you don’t usually plan to buy. You know you need a boiler and you know you will need it servicing, but it’s not a subject that gives you a huge sense of excitement (unlike your oven or your dishwasher might), until something goes wrong. We’re so proud of the Sime Murelle range of boilers that we give you a free warranty with each and every one. Each Sime Murelle boiler comes with an extendable warranty to provide further reassurrance about the boiler you’ve just purchased.

For your peace of mind, our boilers come with 2, 5 or 10 year warranties*. All warranties can be extended for an additional cost. The extended warranty* must be purchased within 60 days of installation, and if your installer has not previously registered your boiler on the Sime website, proof of Gas Safe registration is required.
