Frequently asked questions

Choosing the right system can be confusing. So, if you're not sure or have burning questions that need answering, take a look at our FAQ's below.

On average, a new boiler should last around 10-15 years. This all depends on how well the boiler is looked after - a boiler that is serviced annually and repaired quickly when issues arise, will last a lot longer.

We’re always asked what the best boiler is, but the answer isn’t quite as simple as you’d think.

The best type is one that’s most efficient for your home – so you’ll be using less energy to provide the best heating performance and save more money on your gas bills. Often this is a Combi Boiler, but that doesn't mean a combi will be perfect for you, it all depends entirely on your heating needs.

Same with boiler brands, as every brand has pros & cons associated with them. Most of the time it comes down to personal favourites, so check out our boiler brands and make your own mind up.  

This depends on what work you're having done when installing your new boiler. For the quickest installation possible, when you purchase a boiler swap online we can have it installed within 48 hoursˆ.

Here's our full guide on how long it takes to fit a new boiler.

Yes, we are still installing new boilers during the COVID-19 pandemic - taking every precaution we can. Click the link to and find out exactly what we're doing to keep you safe. 

Yes, absolutely. Just give us a call on 0800 61 22 302 and one of our helpful staff will be able to answer any boiler question you may have. 

“If you replace your old model with an A-rated system and heating controls, you could save about £340 (£28.33 per month) and 1,500kg of carbon monoxide a year” - The Energy Saving Trust.

So, for every £100 you spend on gas, you could be wasting over £40 just on running an inefficient system.

When the time comes to replace your central heating, you may be surprised at how much you have to consider. Research is key if you want to know what central heating system is right for your home.

You'll have to think about what is the right type of system for your home, where you want to install the new boiler and how you can fund the price of a new central heating installation. 

Price breakdown for types of central heating systems:

  • Combi Boiler : £1,549 - £3,000
  • System Boiler : £2,300 - £3,200
  • Regular Boiler : £2,200 - £3,000

A combi boiler (short for combination boiler) is a combination (the clue is in the name!) of a water heater and central heating boiler together in one compact unit.

Here we look at how powerful your combi boiler has to be to work efficiently for the size of your home:

Number of bedrooms Number of bathrooms Combi Boiler Power (kW)
1 bed Flat 1 bathroom 24-28kW
2 bedroom flat/house 1 bathroom 25-30kW
3 bedroom house 2 bathrooms 30-35kW
4 bedroom house 2-3 bathrooms 35-40kW
5 bedroom house 3+ bathrooms 40kW+
  • Applicant must be 18 years or older on application date
  • In permanent UK residence for a minimum of 3 years

Fulfil one of the following employment criteria:

  • In regular, permanent employment (for a minimum of 16 hours a week)
  • Retired from regular employment
    Not working through disability
  • Self employed

The approval of your application depends on your financial circumstances and borrowing history.

Your boiler installation questions answered

What is the cost of a new boiler?

There are various factors that influence the cost of a brand new boiler. The size of your home, the type of central heating system you need or which brand you’d prefer - there's also costs associated with moving your boiler to a different location.

Price breakdown for types of central heating systems:

  • Combi Boiler : £1,549 - £3,000
  • System Boiler : £2,300 - £3,200
  • Regular Boiler : £2,200 - £3,000

Price breakdown for boiler brands we offer:

For any new boiler installation, no matter the central heating choice, you'll be looking to spend around £1,549 - £3,200. 

Why should you get a new combi boiler?

  • Save money on your energy bills - Instead of spending money on repairing your old inefficient boiler, why not buy a new A-rated boiler and save on your energy bills. 
  • Reduce carbon emissions - Boilers are responsible for 60% of domestic carbon dioxide emissions. So, while replacing an old boiler can be pricey, doing so will shave a significant chunk off your carbon footprint - especially if you choose to upgrade to a condensing system.
  • Heat your home efficiently -  Always running out of hot water? or feel like you're using too much energy to heat your home? Your old system may be inefficient for your needs, if so it's definitely time to think about replacing with an updated central heating system that keeps you warm when you need it most. 
  • Efficient new technology - Every year manufacturers are constantly looking at new ways to produce more efficient systems, so choosing to upgrade will help make your heating top of the charts.

When to get a new boiler?

  • Costs too much to repair – The lifespan can vary between 10-15 years, depending on the model and how well it's been looked after. In general, it will cost less to repair a newer system than an older one, as parts for an older system are harder to come by – which means finding and buying them can cost a lot more.
  • Current system isn't heating your home well – Times change and your needs have to be met, if your current boiler can't keep up then it's time to think about upgrading to a more powerful and efficient system.
  • Planning on selling/renting your home? - an old or broken boiler will always be picked up when viewing properties, so if you want offers from potential buyers or tenants you need to upgrade your central heating system - feel free to put the cost of the install back into the price of your home.
  • Save space - Got an old boiler stuck in an odd location? When you buy a new boiler you can choose where to install it, so not only are you getting a more energy-efficient upgrade you also get to move the boiler to a better location. Win-win.
