So, you’ve finally decided to bite the bullet and invest in your new boiler. It may be that your old boiler has broken down and is now beyond repair, or it may be that you are looking to get a new energy efficient one to reduce your gas bills.
Either way, this means it’s time to wave goodbye to your old faulty boiler and replace it with a brand new A-Rated model. In this article, we’ve provided you with some tips and advice to help you successfully choose your new boiler.
So, if you:

There are some key factors you have to take into account while researching the different types and boiler brands.
ErP stands for Energy-Related Product Directive and signifies how much energy a product consumes throughout its lifetime. In the UK, it replaced a well-known SEDBUK (Seasonal Efficiency of Domestic Boilers UK) rating system. The ErP rating classifies the energy efficiency level from the lowest (labelled with the letter G) to A+++, which is the highest level of energy efficiency.
Your boiler efficiency is determined by how much fuel it uses and converts into energy and how much power is wasted in this process. From April 2018, new legislation requires all boilers in the UK to have at least a 92% energy efficiency rating in their fuel use, but you should look for models as close to 100% as possible.
The quieter the boiler, the more likely you can install it anywhere without worrying that it will wake you up. Your best bet is to get a boiler that has a noise level of 50dB or less. That way, even on the echoey attic it will not make a lot of sounds.
This measures how much energy your boiler can use to heat water for your home. For a small apartment you won’t need a big boiler, therefore give your preference to a smaller boiler model. Three or four-bedroom homes will need a boiler with a heat load of 24 to 30 kW, while larger homes may require 35kW or more.
Nitrogen oxides (NOx) refer to increasing emissions of nitric oxide (NO) and nitrogen dioxide (NO2) caused by combustion of fossil fuels. Domestic gas boilers are responsible for 14% of the environmentally harmful emissions in the UK, hence the government has decided to undertake certain measures to reduce the level of polluting emissions.
Therefore, from September 2018, it is mandatory not to exceed the level of NOx emissions of 56mg/kWh for gas and LPG boilers. For oil boilers, the maximum that is allowed is 120 mg/kWh. However, if you would like to contribute to the environmental well-being, choose a boiler with a NOx emissions level of up to 30mg/kWh.
The size of the boiler system varies depending on your property’s size and the number of radiators you have. If you do not have a lot of space for a hot water tank, then you may give your preference to a combi boiler or an electric one.
From old back boilers and a sealed system to gravity and combination boilers, the type of boiler suitable for your property will depend on several factors. To help you make the right decision, we have included the main types of boilers with their advantages and disadvantages:
Because of the generally low installation price, compact size, and high efficiency, this kind of boiler became one of the most preferred types of boilers among UK households. Instead of having a water cylinder to store hot water, they are directly connected to the main water supply. When you turn on a tap, the boiler is triggered and it heats the water instantly.
When searching for a combi boiler, you might stumble on the following types:
Regular boilers, also known as “traditional” or “conventional” are ideal for homes with an already working traditional heating system and a hot water cylinder. These boilers also need to be connected to cold water tanks in the loft area to supply the hot water cylinder with water.
A regular boiler is an excellent choice to replace your old unit with if you already have an older radiator system. The reason for this is that system and combi boilers deliver water in higher pressure and this may cause problems for your radiators.
They require a hot water cylinder but the main heating elements are built into the boiler. The system boiler doesn’t require water tanks in the loft which makes it a good idea for properties where free space is an issue. These boilers are compatible with solar heating systems.
They take their water supply directly from the mains, like a combi, then heat it and store it in a hot water cylinder, like a conventional boiler.
For most people, the budget dictates their choices. Therefore, it is essential to be clear about how much you are ready to spend on a new boiler. The price of a new boiler will depend on several factors:
The price of a new combi boiler varies between £700 and £2000, depending on the boiler power that is required for your property;
Conventional boilers that are available on the market have a price of £650 and go up to £1800 for a unit;
The prices of system boilers range between £700 and £2200 depending on a model and a brand.
Ask your energy supplier if there are any offers in your area that can help you. There are various programs and schemes intended to help people with low income or those who wish to save money. Pay a visit to the Energy Saving Trust website to see whether you are eligible for any type of discount or grant.
To learn more about the ECO scheme, and if landlords and pensioners qualify for a free grant, read this helpful boiler grant guide.
When choosing a new boiler, it is equally important to choose a proper installer. A poorly installed boiler can be insufficient and highly dangerous. Professionals will ensure that your new boiler complies with the current building regulations and provide you with documented evidence, which is needed if you want to sell or rent a property.
It’s always good to get a quote for your new boiler. For the gas and LPG boilers, the plumbing company must be Gas Safe registered. If you plan to install an oil boiler, it is recommended to check if the installer is OFTEC registered. Make sure that your company has carried out all the proper checks and covers any potential damage connected with installation.
