Oil boiler installation costs vary from home to home, so there’s no single figure that applies to everyone. What you pay depends on the size of boiler you need, whether a new oil tank is required, how much work is involved in removing your old system, and the model you choose. At AN Heating, every installation starts with a proper survey so your quote reflects your actual home, not a generic estimate.
What’s Included in an Oil Boiler Installation?
A full oil boiler installation with us typically covers:
- A survey of your existing system, fuel tank condition and installation options
- Safe removal of your old boiler and associated pipework
- Installation of the new boiler, controls and flue system
- An oil tank, concrete base and fuel line, if a new or relocated tank is needed
- Full commissioning, system testing and balancing of your radiators
- Registration, certification and after-care advice
What Affects the Cost of an Oil Boiler Installation?
Several factors shape the final price of your installation:
- The size and output of boiler your home needs, based on your heating and hot water demand
- Whether you need a new oil tank, or whether your existing tank and location can be reused
- How much pipework, flue work or repositioning is required
- Access to your property and where the boiler and tank need to be sited
- The brand and model of boiler you choose
Do You Need a New Oil Tank?
Not always. If your existing tank is in good condition, correctly located and meets current regulations, it can often be reused. If it needs replacing or your current setup doesn’t meet regulations, we’ll include a new tank, concrete base and fuel line as part of the installation.
Does Boiler Size Affect the Price?
Yes. A boiler sized correctly for your home’s heating and hot water demand will cost more than a smaller unit, but getting the size right matters more than choosing the cheapest option, an undersized boiler will struggle to keep up and cost you more in the long run.
Are There Ongoing Savings That Offset Installation Cost?
Often, yes. A modern A-rated condensing oil boiler can improve efficiency to over 90%, and replacing an older, less efficient boiler can reduce your existing heating costs by up to 30%. It’s worth weighing the installation cost against what you’ll likely save on fuel over the following years, especially if your current boiler is old or inefficient.
How to Get an Accurate Price for Your Installation
The only way to get a genuinely accurate price is a home visit. One of our engineers will assess your property, current system and requirements, then give you a clear, no-obligation quote before any work is agreed.
Common Questions About Oil Boiler Installation Costs
Can I get an installation cost without a home visit?
Not an accurate one. Oil boiler pricing depends too much on your existing tank, pipework and access for us to give a reliable figure without seeing the property.
Are oil boilers a good option if I’m not on the mains gas network?
Yes, oil boilers are a reliable, cost-effective heating option for homes off the mains gas network, and we can install an onsite oil supply where needed.
Do you remove and dispose of my old boiler as part of the price?
Yes, safe removal of your old boiler and associated pipework is included as standard in our installation service.
