Replacing an oil boiler
Not every home is connected to mains gas. If yours heats with oil, a worn-out boiler can mean rising bills, breakdowns and an uncertain winter. We replace oil boilers across Yorkshire and beyond with modern, efficient condensing models, fitted by qualified engineers on a date that suits you.
Every oil installation is different, so we start with your home: the boiler you have now, where the tank sits, how the oil line and flue run, and how much hot water you use. That is why the fixed price you get online is for a boiler that suits the property, not just the cheapest option.
Once you have chosen your boiler and date, your engineer removes and disposes of the old unit, fits and commissions the new one, checks the oil supply and flue, and sorts your warranty and compliance paperwork before they leave. Prefer gas? See our new boiler installation options, or LPG boiler installation if you want to stay off the mains.
The price of a replacement oil boiler depends more on the job than on where you live. Boiler type and output, whether it is a straight swap or a conversion, the state of your tank and oil line, flue work and your choice of controls all move the final figure. Like-for-like oil boiler replacements start from £2,895 fitted. Every quote you get online is fixed, so there are no surprise extras on the day.

An oil installation is more than the boiler itself. These are the points our engineers look at on every job.
We check your tank for age, damage, stability and position. Where it is at the end of its life or poorly sited, we advise on replacement and bunding.
We inspect the oil supply line, fit a new filter and check for leaks, so the new boiler gets a clean, reliable supply.
The flue is checked or replaced to suit a modern condensing boiler, with correct clearances and, for outdoor units, weatherproof housing.
We fit a modern programmable thermostat or smart controls, and can upgrade zoning or radiator valves to match how you use the home.
Where you have a hot water cylinder, we check it and the pipework, and recommend a replacement if it is old or inefficient.
Your engineer commissions the boiler, registers the warranty and issues the commissioning certificate, and handles Building Regulations notification.
The right oil boiler depends on your home, your hot water needs and the system you already have. We recommend the one that suits you and show the fixed price online.
The traditional choice for homes with a hot water cylinder and a feed-and-expansion tank in the loft. A straightforward swap where your system already works this way.
A sealed system with a separate cylinder gives strong, even hot water for larger homes and more than one bathroom, with no loft tanks needed.
Heat water on demand without a cylinder, freeing up space. Best for smaller homes with one or two bathrooms and a good supply.
Weatherproof units that sit outside, freeing the airing cupboard or utility room and keeping the oil line short and simple.
Modern condensing oil boilers recover more heat from the flue gases, so they use less oil than an older non-condensing model for the same warmth.
An oversized boiler wastes oil, an undersized one struggles in winter. We size the output to your heat loss and hot water use.

Most like-for-like replacements take one day, and conversions or jobs that include new flue or cylinder work usually take one to two days. Your engineer confirms the plan before they start.
Not always. We check your tank for age, damage, stability and siting. If it is in good condition it can stay, but an old or leaking tank should be replaced, and we will tell you at survey.
If mains gas is available to your property, switching to gas is often possible and we can quote for it. If not, LPG is the usual alternative, and we also fit those. See our LPG boiler installation and replacement page.
