Why you should avoid buying budget brand boilers!

#Saving money

When your boiler breaks is unpredictable but you decide it’s time for a replacement. You get a quote for a boiler replacement but it’s not what you expected. It can be so high you can’t believe it or so low it’s too good to be true.

When you first start searching you will come across lots of boilers at low low prices. Whilst these appear to be attractive and save you money in the short term, in the long term they can create more cons than pros. A big issue is that your boiler might be much more susceptible to needing repairs due to the low quality of budget brands. Further to this, the parts required can take weeks to locate as they aren’t in as high demand as others which definitely suggests a quick fix inevitably means more long term costs a longer period without heating.

Condensing vs Non Condensing boilers

All condensing boilers fitted after the 1st April 2005 have to have an efficiency rating of either A or B, which is particularly important for both the customer and installers. The new boiler plus regulations mean they have to fit these by law, as a result all customers are getting much more efficient boilers.


The main difference is that condensing boilers are up to 99% efficient while a non-condensing boiler is only up to 78% efficient. This means that condensing boilers help you save on average up to £310 per year on gas bills while also reducing your household emissions.

What types of boilers are there?

A combination boiler, commonly known as a combi boiler, heats water as you need it and eliminates the need for a storage tank.

A heat-only boiler, sometimes known as a conventional or standard boiler, means you will have a hot water tank or cylinder where hot water can be stored for later use.
A system boiler is just like a heat-only boiler, but more components are built in. This can make system boilers easier to install than conventional ones, they tend to also take up less space.

What to consider when deciding the size of the boiler you might need?

The heating & hot water capabilities of the boiler. An insufficiently sized boiler means that not all of your radiators will be warm enough, leaving you with cold rooms. Oversized boilers will cause unnecessary strain on your system, driving up maintenance and repair costs.

Tip: When speaking to an engineer about sizing it is important to know: how many radiators you have, how many baths and how many showers are in your home.

The physical size of your boiler and whether it will fit in the space you have it destined for e.g. the airing cupboard, loft or kitchen.

Warranty and lifespan

Whether the boiler you choose is low or high quality/cost is a direct reflection of the length of warranty you get. Manufacturers give longer warranties to higher build quality as they believe they will last longer before failing.


A lower quality boiler may only come with a warranty of 2 or 3 years. Lower quality boilers are unpredictable when it comes to knowing the potential lifespan. They may even not get much further than the low warranty period offered on them. A premium boiler brand such as Worcester, Vaillant or Baxi may have a 10 year warranty due to better components. If well maintained the lifespan could last up to 20 years.

Lower efficiency boilers

Any brand of boiler that’s more efficient can be expensive but will have a much better energy rating. In the long-run you’ll save more than the high initial costs of the model and installation. You must keep this in mind when selecting the best model for you.

One of the most significant disadvantages of budget boiler brands comes with the new regulations for the boiler plus scheme. Boilers must meet a certain efficiency rating as a result of the changes. This will result in higher energy bills with a low-energy rated boilers. Also, the boiler itself will become a lot less inefficient quicker too. A higher quality boiler is a long term solution to reduce energy consumption and a reduced cost to run.

How do you find out how efficient your boiler is?

On all boilers you will see a energy label which displays the efficiency grade for heating and for combi boilers hot water production. You will also find ErP information for energy products through the manufacturers websites. This will give you the efficiency score as well as A to G rating enabling an easy comparison of boilers. This is particularly useful when making the decision to replace an old boiler.


When your boiler breaks is unpredictable but making the right choice when it comes to your boiler isn’t. Making an initially high investment on a new boiler definitely outweighs the short term benefits of a low upfront cost. Choosing a new Worcester Bosch boiler is not only more efficient, it is also more reliable and will save you money in the long term.
