Boiler Warranty vs Guarantee – What’s the difference?
A guarantee is an agreement that the manufacturer will attend to the property to repair or replace the boiler unconditionally if related to a manufacturing fault.
A warranty is a contract to only investigate the problem, but not an agreement to necessarily fix the boiler free of charge.
As a result, a guarantee is seen as the superior option, so is certainly worth bearing in mind. Keep reading to find out which brands offer a guarantee.
Conditions of Cover
Many people aren’t aware that there are conditions you need to meet to keep your boiler warranty valid for the entire coverage period.
Yet the reality is most boiler brands outline a few key requirements you need to meet to maintain your warranty, these commonly include the following:
- Installed by a registered Gas Safe Engineer
- Registration of the warranty within 30 days of installation
- Annual boiler servicing by a registered Gas Safe Engineer
In the event of a breakdown, you are typically asked to pay a deposit before an engineer attends!

Manufacturer warranty lengths
There is no one-size-fits-all when it comes to manufacturer warranties. Each boiler manufacturer set their own and this can vary between their different ranges and models.
All boiler brands typically include a standard warranty ranging from 1 to 5 years, but in today’s competitive boiler marketplace, most manufacturers offer a free extended warranty that ranges from 2 to 10 years.
| Boiler Manufacturer | Period (Years) | Guarantee or Warranty? |
| Viessmann | 5-10 years | Warranty |
| Ideal | 5-10 years | Warranty |
| Worcester Bosch | 5-10 years | Guarantee |
| Vaillant | 5-10 years | Warranty |
| BAXI | 3-10 years | Warranty |
Which boiler manufacturer offers the best warranty?
New boilers are pivotal to the smooth running of your home so finding a warranty that you’re comfortable with is certainly important and common sense says, the longer the warranty – the better.
So which brand offers the best warranty in terms of value?
Currently, the winner has got to be Worcester Bosch boilers!
Why?
They offer a guarantee (not just a standard warranty).
The length is 10 years as standard (when purchased via Heatable).
Worcester Bosch also extends the guarantee terms to their other products if installed at the same time as the boiler e.g. the Greenstar filter.
Just make sure you follow the usual protocols for keeping your warranty valid, which includes:
- Installed by Gas Safe Engineer in accordance with instructions
- Annual boiler service
- Registered within 30 days of installation
- You may be asked to pay a deposit before engineer attendance
Also make sure that if you’re paying monthly for a new boiler installation, the warranty length matches or exceeds the payment period and dodge the risk of paying for a boiler that’s broken and out of warranty.
Situation, boiler warranty registration. How to register the boiler.
Make sure the warranty is registered within 30 days or risk losing the warranty entirely.
Many heating engineers will leave the boiler warranty registration to the homeowner, so do make sure to ask!
