How much does a new boiler cost?

There are various factors that influence the cost of a brand new boiler. The size of your home, the type of system you need or which brand you’d prefer. All have costs associated with them, and we want to help alleviate the confusion.

Combi Boiler

£1,600 - £3,000

  • Ideal for smaller homes
  • No hot water cylinder required - freeing up valuable cupboard space
  • No cold-water storage tank required - freeing up valuable loft space
  • Less pipework needed

System Boiler

£2,300 - £3,200

  • Ideal for homes with 1 or more bathrooms
  • Constant supply of hot water
  • No cold-water storage tank required - freeing up valuable loft space
  • Requires a hot water cylinder

Regular Boiler

£2,200 - £3,000

  • Ideal for houses with 2 or more bathrooms
  • Good option for areas with lower water pressure
  • Requires a hot water cylinder
  • Requires a cold-water storage tank

Combi Boiler

Combination boilers are often smaller than other central heating systems, as they combine two household functions into one appliance – hence the nickname, “Combi”.

This type heats water directly from the mains when a tap is turned on; so, there’s no need for a hot water storage cylinder, or a cold-water storage tank. They are the most popular for small to medium sized homes; due to taking up a small amount of space and having the ability to heat a small amount of water incredibly fast. 

We’d recommend this type for a 1-2-bedroom house with 1 bathroom.

System Boiler

A system boiler is very similar to a combi, as water is supplied from the mains and the heating components are built into the unit itself; the only difference is that a system requires a hot water cylinder to store the freshly heated water. 

Systems don’t need a cold-water tank, but they do require a hot water cylinder to be installed in the home which takes up valuable space. If you already have a system unit, they’re relatively quick to install. 

We’d recommend this type for a 3-4 bedroom house with 2 bathrooms.

Regular Boiler

A regular boiler creates the heated water for a central heating system and stores the rest into a hot water cylinder; If there’s enough hot water stored it can run multiple hot taps simultaneously.

This type requires a cold-water storage tank (often found in the loft) so they’re ideally suited for a larger home with more available space. If you have older radiators, we’d advise a regular boiler as a system or combi could potentially damage them due to high water pressure. 

We’d recommend this type for those with a 4-5-bedroom house, with 2+ bathrooms. 

How can I fund my boiler

The cost of a new boiler will always differ depending on how you choose to pay for it, below is a variety of affordable payment plans we offer to make getting a new energy-efficient boiler incredibly affordable. 


One off cash payment

A one off cash price will always be the cheapest option, as you're not having to pay for any added interest - but it does require a large amount of money suddenly.


Flexible monthly payment

We recognise most people won’t have a lump sum readily available, which is why we offer our Flexible Monthly plan. With a low 5.9% APR, no deposit options and up to 120-month contracts it's no wonder why it's our most popular finance plan. 


Buy now pay later

Our Buy Now Pay Later plan allows you to purchase a boiler now and pay for it 12 months later - with absolutely no deposit needed. 


Interest free credit

We also offer Interest Free credit, but that's only available for any package over £2,500. We would also require a deposit or either 30% if you want to pay back over 12 months, or 40% if you want to pay back over 24 months - but you won't have to pay a single penny in interest. 


Ultimately, this is down to personal choice; either pay a lump sum in one go with the best price or start a payment plan and potentially pay more over a set course of time.


Just remember, if you do apply for a finance plan you’ll be subject to a credit check, so if you have bad credit you’ll likely be rejected and it will affect your credit rating – so only go for this option if you know you’ll be accepted.


Payment plans


The price of a new boiler plus installation will range anywhere from £1,700 – £3,500; depending on how much work is required. We’d recommended you book a free home survey to get a Gas Safe engineer to come to your home and inspect how much work is required. When they’ve completed surveying your home, they’ll offer a no obligations quote that’s valid for 28 days, so you have time to research what’s best for you.

We hope that’s cleared up some confusion, and whatever your heating needs are, just know we're here to help on your journey to a warmer home.
