Choosing a boiler

First and foremost, regardless of the boiler type, investing in a newer model will save you £££s in the long-term. The higher the energy efficiency of your boiler, the less energy you’ll use and the more money you’ll save. Simple. Over a year you can save hundreds, and across the boiler’s lifetime, it begins to pay for itself.

Not to mention, repair fees and replacement parts for older boilers tend to be more expensive and, over time, costs can add up. Installing a new boiler with an extended warranty can often be the cheaper option.

As an added bonus, the more energy efficient your boiler, the better it is for the environment. So, you can save the pennies and reduce your carbon footprint at the same time – great!

We work with the best boiler brands to offer you the best products on the market. Although, it’s not as much about what boiler is best, but more about what boiler is the best for you.

If you have a larger home with a higher demand for hot water, a regular boiler may be the best choice. It’s also important that you’re aware of each boiler’s energy efficiency rating so you know exactly how much you’ll save in the long run.

For those with smaller homes, the more compact combi boiler could be more suitable. Whatever your circumstances, we are here to help you make the perfect decision for you.

When we talk about boiler size, we don’t mean its physical dimensions. The energy output in kilowatts (kW) determines how much energy a gas boiler produces, and different homes need different sizes.

No matter how big your home is, it’s important to get the boiler with the right output for you. If you choose the wrong boiler size, you may struggle to heat your home and run out of hot water on one hand, or waste £££ creating extra energy you don’t need.

How much energy you need to produce is determined by several things.

For instance:

  • How many radiators you have
  • How much hot water you need
  • How well insulated your home is
  • What type of fuel your home uses

All these factors, and more, play a part. But don’t worry, we’re here to ask you the right questions to make sure you feel confident in your decision.

  • What types of boilers are available? Each boiler has its benefits, but it’s important to make the right decision for your specific circumstances.
  • How big is your demand? Larger houses tend to have a larger demand for hot water and heating, while smaller properties have less. Working out how much water you use or how often you use the heating will help you make the best choice.
  • Do you have enough space? Some boilers need to be paired with cold water tanks and hot water cylinders. If you have limited room or loft space, choosing the more compact option is vital.
  • Is your chosen boiler the most energy efficient? Look out for high energy efficiency ratings – the higher it is, the less energy you’ll use when heating water, the more money you’ll save.
  • It’s very energy-efficient and cost-effective, as the water you need is heated almost instantly, rather than being stored for future use.
  • The compact size provides a clean look and a great way for you to save space.
  • It’s perfect if you have a smaller property that has little to no loft space for an additional cold water storage tank.
  • Less pipework needed in your home typically makes the installation process quicker and cheaper.

The cost to replace your boiler is impacted by a few important things.

  • The boiler’s brand and model
  • Its physical size and energy output
  • The location(s) of your old boiler and where you want your new one
  • To get started, the best thing would be to get a full quote based on your specific needs.

An average household’s boiler lasts between 10 and 15 years, depending on how well it’s looked after and if it has regular servicing.

Through the Government’s Boiler Upgrade Scheme, you could be eligible for a grant to partly cover the cost of replacing fossil fuel heating systems with a heat pump or biomass boiler. Make sure you’ve checked if you’re eligible.

Energy efficiency

Simply put, the more efficient your boiler is, the less energy you’ll waste and the more money you’ll save. Older boilers often have lower energy efficiency ratings, which means less of the energy you pay for to power your boiler is actually converted into heat for your home. It’s important to check your new boiler’s efficiency rating, and we’ll help you pick out the right option for your home.

By replacing an old gas boiler with a new A-rated condensing boiler, you could save an impressive £310* per year on your energy bills.

* This estimated figure is from the Energy Saving Trust website and is based on fuel prices as of April 2024. The figure is based on replacing an old G-Rated boiler and installing a new A-rated condensing boiler with thermostatic radiator controls (TRVs), as well as a new programmer and room thermostat. This applies to gas heated semi-detached homes in England, Scotland and Wales, but savings will vary depending on the size and thermal performance of your home.

Depending on the age of your boiler, it will have one of two possible energy efficiency ratings. For newer models made after 2015, there will be an Energy-related Products (ErP) rating. If your boiler was installed before 2015, it should have a Season Efficiency of a Domestic Boiler in the UK (SEDBUK) rating.

Both of which would be found either on the boiler itself, or in the paperwork you received after the install. Before buying your new boiler, we’ll let you know the energy rating and make sure you’re happy.

ErP Rating: The ErP rating is the current energy efficiency rating for all boilers installed after 2015. Set up by the European Union, the rating system is designed to reduce emissions by meeting certain energy-saving criteria.

The rating uses an A-G letter system to rank new boilers on their efficiency, with A+++ as the most efficient and G as the least. To give context, an A-rated boiler is at least 90% efficient, while a G-rated boiler’s efficiency is 70% or less.

SEDBUK Rating: Before 2015, boilers were judged on their energy efficiency by the SEDBUK Ratings, which is split into two types. SEDBUK 2005 uses a letter system similar to the ErP ratings – A being the most efficient and G being the least.

SEDBUK 2009 uses percentages – the higher the percentage, the more energy efficient). This will be found on older boiler models, but the system was replaced by ErP ratings in 2015.

We strive to work with boiler brands who provide boilers with market-leading energy efficiency ratings. A-rated boilers with an efficiency rating of 90% or higher will provide the best value to your home.

First and foremost, regardless of the boiler type, investing in a newer model will save you £££s in the long-term. The higher the energy efficiency of your boiler, the less energy you’ll use and the more money you’ll save. Simple.
