A new boiler is a big investment which if maintained, will give you and your family years of hot water and central heating comfort. But if they go wrong, you could face some hefty repair bills, which is why a boiler warranty is an essential consideration.
An effective warranty offers you peace of mind as should your boiler develop a fault, or even break down, the manufacturer will cover the cost of the repair as long as it is within the warranty period. And as these can run from one to 10 year warranty, choosing a comprehensive policy can be invaluable in keeping your home warm and happy.
Most manufacturers offer different warranties for different models in their range, plus the option for you to extend the term. So, if you are looking to replace your old boiler, it is important to shop around to get the best boiler warranty for your budget and needs.
To help you get started in your search, we take a look at the top five Combi boiler brands with the best warranties so you can see who offers the best warranty and what protection you can expect for your money.
|Worcester Bosch||2-12 years|
Viessmann offer a standard guarantee on all their boilers, including the Vitodens 050 w and their Glow Worm range, that they will fix or replace any material or manufacturing defects free of charge, within two years of delivery. They also offer a comprehensive three or five-year parts and labour warranty on most of their boilers, which can be extended to up to 10 years on selected ranges, although the boiler must be fitted by a Viessmann-trained engineer. Other standard conditions, including annual servicing also apply.
Worcester Bosch Warranty
Worcester Bosch is one of the boiler manufacturers that have moved over to offering a guarantee, starting with a guarantee of two years on all their boilers as standard. This means they are guaranteed against any material or manufacturing faults during the guarantee period. This guarantee period can be extended, depending on the boiler range and model, with their Lifestyle range offering an industry best of 12 years. Conditions for guarantee extension include using a Worcester Bosch Accredited Installer.
Ideal also offer an impressive 12-year warranty, buy but this does mean you need to extend the full 10-year warranty by two years and is only applicable to their Ideal Max combination boiler range, which must be installed by a Max accredited engineer. For the rest of the Ideal boilers range, including the Ideal Logic and Ideal Vogue, the warranties range from two to seven years, which can all be extended by 12 months at an additional cost. If you don’t register your new boiler within 30 days of installation, you will default to just 12 months’ warranty cover.
Standard Vaillant Warranty
A stalwart of the UK boiler market, Vaillant offer two-to-five-year labour and parts warranties as standard, but it does depend on the model you choose. You can also opt to extend your warranty to up to 10 years, but it does depend on you only using a Vaillant Advance installer. Other requirements include an annual service (which is not included in the warranty) and all repairs must also be carried out by a Vaillant engineer.
All BAXI boilers come with a warranty to cover the costs of mechanical and material faults and breakdowns, with the standard cover ranging from two to seven years. However, the company will offer limited time offers of 10 year warranties on selected new boilers so it’s worth keeping your eye out for these special offers. All BAXI warranties only relate to the boiler and integrated controls and if you don’t register your new boiler or you don’t adhere to the conditions, the warranty will be limited to 12 months from the date of installation.
What is a Boiler Warranty?
A boiler warranty aims to give you peace of mind when it comes to your new boiler, as you know it will be covered should it break down or develop a fault. This means that should your boiler become faulty or breakdown during the warranty period, repairs or part replacement will be covered by the manufacturer. Labour costs, however, may not be included.
A warranty can last anywhere from one year to the best 10 year warranty boilers, with most new boilers including a one-year warranty as standard. Different boiler manufacturers will offer a long warranty on different boiler models as well as offer purchasers the option to pay to extend their warranty period.
All warranties only remain valid if you adhere to the terms and conditions, which can differ depending on the manufacturer, so it is important to always read the T&Cs small print. However, typical warranty conditions include only using a Gas Safe registered engineer to install the boiler, annual servicing and only using manufacturer-approved parts.
Failure to abide by a boiler manufacturer’s terms and conditions may result in the invalidation of the warranty.
What Does the Warranty Cover?
Different manufacturers will offer different levels of cover with their warranty, so do read the warranty for your boiler, so you are clear as to what it will, and will not, cover. However, as a guide, most boiler warranties will cover against faults or breakdown involving manufacturing or material defects, during the warranty period. This means they will fix or replace the faulty parts in your boiler, as long as you have followed their terms and conditions.
What is the Difference between a Guarantee and a Warranty?
While all new boilers come with a manufacturer warranty, they can also come with a guarantee as standard, and while the intention of a warranty and a guarantee are largely the same, there is a subtle difference. And that is, with a guarantee, the manufacturer promises to repair a boiler, whatever the cause of the fault or breakdown, for a set period of time after purchase. This differs to a warranty, which will have certain conditions as to what has caused the fault and terms you need to have adhered to.
Worcester Bosch was the first boiler manufacturer to switch over to a boiler guarantee, and others are now following. It is down to consumer choice as to which policy offers them the best protection and value, so always read the terms and conditions, whether it is a warranty or a guarantee, to get the right boiler package.
How to Keep my Warranty Valid
To ensure your warranty is valid and you can access its support should your boiler develop a fault, it’s important to follow all its conditions. As a guide, you will need to:
- Ensure your boiler is registered with the manufacturer within 30 days of its installation. Check whether your installer is going this, or if it is your responsibility.
- Only use a registered and authorised Gas Safe engineer when it comes to your boiler installation.
- Complete all the necessary paperwork and keep it safe.
- Have your boiler serviced annually by a Gas Safe registered engineer and obtain a certificate to file with your other boiler documentation.
- Use your boiler within the manufacturer’s instruction manual and don’t adapt any of its systems.
- Do not attempt any repairs yourself – always use an authorised and regulated Gas Safe registered engineer as any damage caused by self-repairs can actually invalidate your warranty.
- Extend your warranty if relevant, to keep your boiler covered.
Working within the terms of your warranty will not only ensure you have a working boiler and heating system but can also save you money, time and hassle in the long run.
