New Oil Boiler Replacement: Prices & Installation Costs

Buildings with an oil boiler may use it for either hot water or heating or both. In this sense, they must be regarded as a critical component of the home; nevertheless, few building owners are aware of what to do when they have problems with their boilers, or whether or not it is the appropriate equipment for their demands.

A new oil boiler will assist to improve your home’s efficiency, safety, and overall comfort. New oil boiler prices start about £1,000 for the unit, with installation costing an additional £500 to £1,000. In this article, we’ll walk you through all you need to know about oil boiler prices.


Before moving forward it’s better to understand what is an oil boiler? 

An oil boiler uses oil to provide central heating and domestic hot water to a home. The boiler’s oil is stored on the premises in a storage tank. This is in contrast to natural gas, the most prevalent boiler type in the UK, which is provided through the main supply as and when it is required. Oil is a fantastic choice for properties that aren’t linked to the generating station since it can be stored on-site.

Oil boilers are offered in three types: combi, system, and standard. And each of these oil boiler types has its own set of advantages and disadvantages that make them appropriate for certain property kinds.

While there are several different types of boilers available for residential homes, the way they work is similar.

A boiler has a heating component — either gas flame or oil — that creates the heat. Water pipes run through the boiler and a heat exchanger. The heat exchanger component allows the heat source to warm up the water without direct contact. Circulator pumps then push water from the boiler into the central heating system, to a water storage tank, or directly to your hot taps depending on your particular type of boiler.


Your boiler will come to a point when it will no longer be able to work as effectively as it previously did. This might be in the form of efficiency, dependability, or overall performance.

If you’re not sure whether it’s time to replace your oil boiler, here are several indicators that it is:

  1. Your existing boiler was installed over a decade ago.
  2. It’s less effective than it used to be, which has resulted in higher heating expenditures.
  3. You’ve heard some strange noises coming from the boiler or heating system.
  4. Constantly encountering problems
  5. Heating engineers have a difficult time locating new components.
  6. Your house isn’t as warm and comforting as it once was.


The kind of boiler installed, the work necessary to complete the installation, and whether or not it runs as a hot water heater or as a part of the heating system all have an influence on the cost of an oil boiler installation.

The overall cost of a new replacement oil boiler in the UK, including installation, may range between £2,500 and £4,500.

If you’re installing a completely new system, the cost of replacing the central heating system, including the redirection of the radiators and water pipes, may well approach £3000.

The cost of an oil boiler installation for each of these boilers will vary from technician to technician; therefore we strongly advise checking multiple estimates to ensure you get the best deal.

On average, you may anticipate paying between £500 and £2,000 for labor and installation of your new boiler, with the amount depending on a variety of factors.

  1. Labor cost
  2. Moving boiler to a new location
  3. Shifting to different boiler form
  4. Replacing oil storage tank


When considering the usage of a hot water heater for household supplies and as a core element of a heating system (even though this function is not provided during the summer months), it is an energy-efficient approach to heat a home.

  1. Replacing a boiler is a separate procedure, and it is usually preferable to examine garage repairs before going to a workshop for a replacement item. The typical cost of replacing an oil boiler is roughly $4,000, whereas greater efficiency choices cost around $7,000.
  2. The project also necessitates the installation of an oil tank, the cost of which will vary depending on size, locality, and any particular needs.
  3. Can the fuel type of a boiler be changed? Yes, in a summary. The question is whether it is a cost-effective choice. Gas furnaces are significantly cheaper to operate, but oil is much simpler to get. However, this involves the use of an oil tank, which must be properly constructed and can cost anywhere from $500 to more than $3,000 depending on the complexities of the tank and its placement.
  4. Before any oil burner can be used, the chimney must be thoroughly cleaned.
