Our Range of Grant Boilers
We offer a complete selection of Grant's oil-fired boilers, ensuring you can source the perfect unit for your specific project requirements.
The main types of boilers that Grant offers are:
- Combi (Combination) Boilers: These are a very popular choice as they provide both central heating and instant hot water directly from the boiler, without the need for a separate hot water cylinder or cold-water tank. This makes them a great space-saving option, particularly for smaller to medium-sized homes. Grant offers both internal and external combi boilers.
- System Boilers: For larger homes with multiple bathrooms and a high demand for hot water, a Grant system boiler is a great choice. These boilers work with an unvented hot water cylinder to ensure a constant supply of hot water to numerous outlets simultaneously. As a sealed system, they don't require a cold water tank in the loft, simplifying installation.
- Regular (Conventional or Heat-Only) Boilers: These are the traditional type of boiler often found in older heating systems. They require both a hot water cylinder and a cold water storage tank, typically located in the loft. They're suitable for homes that already have this setup and for larger properties with a high demand for hot water and multiple bathrooms.
The Key Features of Grant Boilers
- Efficiency: Grant is a pioneer in the field of high-efficiency, oil-fired condensing boilers. Their commitment to efficiency is a primary reason for their popularity.
- A-Rated Efficiency: Many of their boilers, particularly those in the Vortex and VortexBlue ranges, are A-rated for efficiency, meaning they achieve high efficiency ratings. Some models can reach up to 94.5% space heating efficiency. This is a significant improvement over older, non-condensing boilers, which can operate at efficiencies as low as 60-70%.
- Condensing Technology: Grant's boilers use a highly innovative, patented stainless steel heat exchanger to capture and reuse waste heat from the flue gases. This process, known as condensing, allows the boiler to extract more heat from the same amount of fuel, leading to reduced fuel consumption and lower energy bills.
- Low NOx Burners: Grant's VortexBlue series features advanced blue flame burners that produce ultra-low NOx emissions. This not only makes them more environmentally friendly by reducing harmful emissions but also ensures a cleaner, more efficient combustion process.
1. Ease of Installation for Engineers / Fitters
Grant boilers are designed with the installer in mind, which is a major factor in their widespread adoption.
- Installer-Friendly Design: The boilers are known for being straightforward to install and service. Features like front service access to the burner and internal components make annual maintenance easier and quicker for heating engineers.
- EZ-Fit Flue Systems: Grant offers a comprehensive range of EZ-Fit flue systems that simplify installation. These systems come in various configurations (low-level, high-level, vertical, etc.) and are compatible with all Grant boilers, giving fitters flexibility in a variety of installation scenarios.
- Simple Commissioning: The boilers are designed for a simple and effective commissioning process, ensuring that they are working at peak efficiency from the moment they are installed. This not only benefits the customer with lower running costs but also provides peace of mind to the engineer that the job is done right.
2. Range of Options and Designs
Grant offers a versatile range of oil-fired boilers to meet the specific needs of different properties.
- Combi, System, and Regular (Heat-Only): They provide a full spectrum of boiler types to cater to various hot water and heating demands. This includes combi boilers for homes that need instant hot water and have limited space, as well as system and regular boilers for larger properties with multiple bathrooms.
- Internal and External Models: Grant is well-known for its external (or outdoor) boiler models, which are perfect for homes where internal space is at a premium. These boilers are housed in a robust, weather-resistant casing and are designed to perform reliably in all weather conditions.
- Boiler House and Utility Models: The range includes designs specifically for installation in a boiler house, garage, or utility room, offering flexibility in placement.
- Wide Output Range: Their boilers come in a broad range of outputs, from 15kW up to 70kW, ensuring there is a suitable model for everything from a small flat to a large commercial property.
3. Good Warranties and Support
Grant provides strong guarantees and support, which gives customers and installers confidence in their products.
- Extended Warranties for G1 Installers: While standard warranties are available, Grant offers significantly extended warranties when the boiler is installed by a certified G1 Installer. This G1 accreditation scheme ensures that the installer has been trained by Grant, providing a higher standard of installation and service.
- Product Guarantees: Depending on the model and whether it is installed by a G1 installer, guarantees on a Grant boiler can be up to 10 years for the heat exchanger and several years for other parts. This is a testament to the durability and quality of their components.
- After-Sales Support: Grant has a reputation for excellent after-sales support, with a dedicated technical team and a network of approved installers to assist with servicing and repairs.
Selecting the Right Grant Boiler for Your Project
Choosing the correct boiler involves considering the property's size, the number of bathrooms, and the existing heating system.
- For smaller homes with one bathroom, a Grant combi boiler is often the most efficient choice. It provides hot water on demand and saves space.
- For larger properties with multiple bathrooms, a system boiler paired with an unvented cylinder will deliver the high hot water flow rate needed to meet demand.
- For homes with a traditional, open-vented heating system, a regular (heat-only) boiler is typically the most straightforward replacement.
Grant also offers a range of outputs, so it's essential to calculate the heating and hot water requirements of the property to select a boiler that is powerful enough without being oversized. Our in-branch teams are always on hand to offer expert advice if you need help choosing the right model.
How Much Do Grant Boilers Cost?
- Grant's success lies in its ability to combine award-winning efficiency with practical, installer-friendly designs and comprehensive customer support, making them a trusted name in the heating industry, particularly for off-gas properties. Yet, their competitive pricing for boilers is also a big pull for customers, especially for their oil boilers you can find at City Plumbing starting from £1600.

Who Are Grant Boilers?
Grant Engineering, often known simply as Grant, is a long-established manufacturer of heating products, with a history spanning over four decades. While they also offer renewable heating solutions like air source heat pumps and solar thermal products, they are particularly well-known and regarded for their oil-fired boilers.
Why Are Grant Boilers So Popular?
Grant boilers have built a strong reputation and are a popular choice for several reasons, particularly for homes that are not connected to the main gas grid:
- Award-Winning and Highly Efficient
- Designed for Reliability and Durability
- Innovation and Environmental Responsibility
- Variety of Models for Different Needs
- Installer and User-Friendly Design
- Strong Guarantees and Support
What Types of Boilers Does Grant Offer?
Grant primarily specialises in high-efficiency oil-fired boilers, which are a popular choice for homes not connected to the main gas grid. Their boiler range is quite extensive, offering a variety of types to suit different home sizes, layouts, and heating demands.
The main types of boilers that Grant offers are:
- Combi (Combination) Boilers: These are a very popular choice as they provide both central heating and instant hot water directly from the boiler, without the need for a separate hot water cylinder or cold water tank. This makes them a great space-saving option, particularly for smaller to medium-sized homes. Grant offers both internal and external combi boilers.
- System Boilers: Similar to a combi boiler, a system boiler heats water directly from the mains and provides central heating. However, it requires a separate unvented hot water cylinder to store the hot water. This makes them suitable for larger homes with multiple bathrooms where there is a high demand for hot water at the same time. Grant's system boilers don't need a cold water tank in the loft, as they're a sealed system.
- Regular (Conventional or Heat-Only) Boilers: These are the traditional type of boiler often found in older heating systems. They require both a hot water cylinder and a cold water storage tank, typically located in the loft. They're suitable for homes that already have this setup and for larger properties with a high demand for hot water and multiple bathrooms.
In addition to these types, Grant also offers:
- Internal and External Models: Grant provides a wide range of boilers that can be installed inside a property (e.g. in a kitchen, utility room, or boiler room) or outside. External models are a great solution for homes where internal space is at a premium.
- Renewable and Hybrid Solutions: As part of their commitment to sustainable heating, Grant also manufactures and provides renewable products like air source heat pumps and hybrid systems that combine a heat pump with an oil-fired boiler.
