Getting the right warranty for your boiler

The right warranty could be the deciding factor between one boiler and another.

The longer the manufacturer is prepared to give a warranty for, the more confidence they have in their boiler that it will not break and need repaired, otherwise they will have to foot the bill.

A boiler is essential to keep your home warm and provide hot water but it’s a big investment. A guarantee gives you peace of mind that your investment is protected for longer.

At Add Heat we offer a 12-year guarantee to protect your Worcester Bosch boilers for longer, saving you money and inconvenience.

When you rely so heavily upon your heating system it is best to get the longest possible warranty or guarantee to protect you from any potential problems.

It gives you peace of mind that in the unlikely event it does happen to break, you won’t be out of pocket or without heating for long.

Why get a new boiler?

Maybe you’ve noticed you’re heating isn’t as efficient as it once was, or maybe your boiler is heading towards a milestone birthday.

There are lots of reasons you might be considering a new boiler.

Your home takes longer to heat up

If your radiators are taking longer than usual to warm, then there could be a blockage. You can try bleeding your radiators first or call an engineer if this doesn’t work.

Different smell or noises

If there is any kind of smell coming from your boiler, you need to get this checked immediately.

The same goes for any noises that are not usual for your boiler.


If your heating bill seems to keep rising even when the heat in your house isn’t, then your heating is not energy efficient. Newer boilers will be energy efficient which are better for the planet and for your pocket.


If your boiler is ten years of age or more, it might be time for a replacement. The older your boiler, the less efficient it will be. It may also be difficult to get parts to repair it, making it more expensive to maintain.

What’s the difference between a warranty and a guarantee?

The Worcester Bosch is unlike most other manufacturers as they offer a guarantee, not a warranty.

Boilerguide report Worcester Bosch has one of the best boiler guarantees among boiler manufacturers.

A guarantee and a warranty have one difference. A guarantee is a promise to repair your boiler no matter what the cause.

A warranty will only cover repairs if it is a manufacturing fault.

Why do you need a guarantee or warranty?

The most obvious reason for a guarantee is to save you money when your boiler breaks down.

If your boiler is under guarantee, then the manufacturer will fix this for you without any inconvenience or cost for you.

If your boiler breaks suddenly you don’t want to be stuck in the middle of winter with no heating and a long waiting list for an engineer.

A guarantee gives you peace of mind that you won’t have that problem.

Home insurance more than likely won’t cover any issues with your boiler unless you have this added to your insurance.

Worcester boiler warranty

For most boilers there is a one-year standard warranty. Worcester boilers have a standard of between 2 to 10 years.

Worcester 12-year warranty offer on Worcester Lifestyle boilers

What does a guarantee cover?

It covers any fault your boiler may have for up to 12 years.

It is a legal promise that Worcester Bosch will replace or repair your boiler issues within a certain timeframe.

There’s no waiting to find an available engineer or having to deal with a repair that drags on for weeks.

What voids a boiler guarantee?

If you do not service, your boiler on a yearly basis then your warranty or guarantee will not be valid.

If the boiler is not correctly installed it can lead to your guarantee being invalid which is why you should use an accredited engineer.

You must register your boiler within 30 days from it is installed.

How to get the most from your boiler

Inspect your boiler

You don’t have to be an engineer to check your boiler. Have a look at your boiler every now and again to check if seals are intact and check there are no icons on your display.

Check there are no leaks or signs of leaking from your overflow pipe and that the flame is blue, not yellow or any other colour.

Keep your boiler ventilated

Your boiler will usually be situated in a storage area of your home. Make sure you don’t pile up coats, towels, or anything else against it.

Which leads us to our next point.

Check your carbon monoxide alarm

Carbon monoxide poisoning can be fatal, so ensure you have a working carbon monoxide alarm.

These alarms can last for years and should have the date on the alarm for you to see.

Press the button on your alarm every so often (even if it is still in date) to check it is working. It could save the life of your family and yourself.

Service your boiler

Just like servicing your car, a boiler service keeps your boiler running at its best.

It reduces the likelihood of it breaking suddenly and leaving you without heat or hot water.

It also maintains your boiler, so it has a longer life, which saves you money on repairs and having to buy a new boiler.

Check your pressure

With a Worcester Bosch boiler you shouldn’t need to check your pressure as their boilers have innovative technology to keep your pressure maintained.

A boiler needs to be at a certain pressure to enable it to send hot water around your home.

The pressure gauge on your boiler should indicate the level it should be sitting at.

Check your radiators

You will soon notice if your house takes longer to heat up or doesn’t seem to be as warm as usual.

The first thing to check is your radiators. When your heating is on, carefully check each of your radiators to see if there is any cold areas.

If there is then simply use a radiator key to adjust the knob on each radiator.

Make sure to put an old towel or rag under the knob to catch any water that leaks out. The last thing you want is to damage your flooring.

Include an engineer’s number on your boiler

In the event of your boiler breaking, it is best to have an emergency number on your boiler, making it quick and convenient to get the problem sorted.

At Add Heat our numbers are:

Wilmslow: 01625 464 235

Cheadle: 0161 667 1490

You should also have a note of when your boiler was last serviced on your boiler along with the manufacturers phone number for your convenience.

A boiler is essential for your comfort in your home but it’s a big investment. Make sure to get the longest guarantee you can to keep your money where it’s supposed to be, in your pocket.
