How do oil boilers work and what are the benefits?
Oil-fired boilers are an ideal solution for properties that aren't connected to mains gas. Oil-fired boilers are particularly popular in rural areas or properties off the gas grid due to their independence and powerful heating performance.
Key benefits of oil-fired boilers:
- They work like a gas boiler but use a stored supply of oil to heat the water used for your radiators and taps.
- These boilers are efficient and economical, so you'll get a good amount of energy from every fill-up and lower energy waste.
- With an efficiency rate of up to 98%, you'll be making an eco-friendly decision while saving energy when you choose a new oil boiler.
- Suitable for a wide range of properties, from small homes to large commercial buildings.

Which Oil Boilers are available at City Plumbing?
Perfect for compact homes, an oil combi boiler provides both heating and hot water from a single unit. Water is heated on demand, meaning there’s no need for a separate storage tank - ideal for saving space.
We stock a variety of models, including:
- Oil Combi Boilers – Provide heating and hot water from a single system. A combi heats water from the mains to provide instant hot water when needed.
- Oil System Boilers – Supply heat directly to your radiators by igniting oil to warm up cold water to provide for taps, showers and radiators.
- Oil Heat Only Boilers – A open-vent system that provides heat to radiators, taps and showers by drawing water from a cylinder rather than the mains.
- Oil Boiler Packs & Accessories - We also stock oil boiler packs that include flues, controls, valves, and all the essential parts you need for a smooth installation.
We also have oil boiler packs that contain the flues, parts, spares and accessories you need.
What is the cost of a new oil boiler in the UK?
The cost of an oil boiler depends on its size, brand, and efficiency rating. Prices typically range between £1,000 and £3,500, excluding installation.
For a more accurate estimate, you’ll need to consider factors like property size, water demand, and whether you’re replacing an existing unit or installing from new.
Time for an upgrade? A modern, energy-efficient oil boiler could save you up to 30% on fuel costs compared to an older model.
