Grant are an award-winning and innovative heating company with over 40 years of heritage. For many years Grant specialised in oil-fired condensing boilers but more recently the company has added innovative renewable technologies like air source heat pumps, biomass boilers, solar thermal and hybrid systems to their range.
For properties that aren’t connected to the gas network, an oil boiler is a great alternative to a gas boiler as oil is a fuel that can be stored onsite. Grant oil boilers are available as combi and regular units so there’s a suitable heating system for small and larger properties. When looking for a suitable oil boiler, you will need to take into account the output rating, efficiency, warranty and potential cost of each unit.
- Output rating: Your replacement boiler needs to have an output rating that suits the central heating and hot water demands of your home. Otherwise your new boiler will be unable to meet demand or your energy bills could begin to rise.
- Efficiency: Oil boilers burn oil to provide central heating and hot water but as a fossil fuel some waste gases are produced as it’s burned. This means that not all of the oil will be converted into usable energy. The higher the efficiency of a boiler, the more fuel it’s capable of using, making it more likely that it will help to lower your energy bills.
- Warranty: All boilers come with a warranty, which means that you’re protected by the manufacturer in the unlikely event of a fault. Depending on the manufacturer and boiler model, the length of the warranty and what it covers will vary. Grant oil boilers are covered by a 2 year warranty as standard.
- Price: Grant oil boilers aren’t the most budget-friendly with prices ranging from around £1,200 up to £3,100.
To find the most suitable oil boiler for your home, it’s well worth taking the time to compare boilers. Our Boiler Comparison Tool allows you to compare the output rating, efficiency, warranty period and potential cost of up to 4 different boilers. Hit the ‘add boiler’ symbol to add a boiler into your comparison and don’t forget to include your existing boiler.
Compare Grant oil-fired combi boilers
Grant oil combi boilers provide central heating and hot water on demand as and when needed by heating up water directly from the mains. Grant manufacture a range of different combi boilers with output ratings ranging from 21 kW up to 36 kW and you can take your pick between a unit designed for internal or external installation.
Compare Grant regular boilers
Regular boilers are best installed as part of a heating system which already includes a regular boiler. So if your home doesn’t already have a regular boiler, a heating engineer is likely to recommend a combi or system boiler instead. With output ratings of 16 kW right up to 70 kW, a Grant regular oil boiler can be installed in properties of varying sizes.

Benefits of Grant combi boilers
Energy efficiency is a top priority for Grant Boilers and their popular Vortex Pro combi boiler is no exception.
Winner of Which? Best Buy in 2008, this range is still proving a great choice in UK homes. Quick and simple to install as well as compact and unobtrusive, choosing the Grant Vortex combi makes sense for lots of reasons.
Combi boilers are one of the most popular choices for homeowners, not least because they deliver hot water for taps or radiators on demand.
The other big benefit is that there is no need for a bulky hot water tank or a large hot water cylinder to be installed either.
Many modern homes don’t have a traditional ‘airing cupboard’ or sometimes even a loft – which means that a compact combi boiler really is the only effective choice in these cases.
- Approved by the Energy Saving Trust
- 2-year boiler warranty and 5-year heat exchanger warranty
- High energy efficiency rating
- Available in a range of outputs
- Ideal for smaller off-grid homes
When you’re working to a specific budget for your new boiler, and you’re keeping an eye on the ongoing running costs for heating your home in the colder months, it pays to take time to do the sums and work out the best deal for you.
When considering the cost of a new Grant combination or ‘combi’ boiler, take into account the purchase price, the installation cost (using a qualified and regulated heating engineer) and the overall running costs for fuel, servicing and maintenance.
Once you have the complete picture, it’s much easier to manage. And you will hopefully be pleasantly surprised at how much more energy efficient and therefore cheaper to run a new boiler proves to be. Get quotes for a new Grant boiler.
Grant regular boilers
A regular boiler system comprises three things – the boiler itself, a hot water cylinder, and a cold water storage tank – which is the part that usually goes in the loft.
Regular boilers are common in older properties, although modern versions are now sleeker and more energy efficient.
So you might think you just want a simple, like-for-like replacement for your regular boiler, however there are still some decisions to be made about exactly what system would be best for your home.
Grant Boilers have various options in their regular range so one of the big considerations is where the boiler needs to go.
With a choice of floor standing for utility rooms, wall-mounted for kitchens and even an external boiler, there’s plenty to think about.
You’ll also need to take into account the size of your property and the number of radiators and bathrooms the boiler will be serving.
Grant’s regular range offers a choice of options.
Benefits of a Grant regular boiler
- Benefit from much greater energy efficiency by replacing an old boiler
- You may be able to utilise existing pipework if you’re simply replacing an older regular boiler
- Varying output options to meet differ levels of demand
- Standard warranty automatically included for extra peace of mind
- Easy-to-use controls
You’ll probably already be aware that a new boiler is a significant outlay so it’s important to take the time to shop around to ensure you get exactly the right system for your needs – and of course make sure you aren’t paying over the odds.
A good tip is that it’s always a good idea to get multiple quotes for your new boiler installation. Contacting three reputable heating engineers for a quote is good practice as individual rates can vary quite a lot. Get quotes for a new Grant boiler.

Grant Boiler Warranty
Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame. Some warranties include both parts and labour while others may only cover parts. The most important thing to remember is to get your boiler serviced by an OFTEC registered engineer every year as failing to do so is likely to invalidate your warranty. For more detail about this brand’s warranty (including the small print) take a look at Grant Boiler Warranty.
Grant Boiler Repair Advice

The product range in includes the Aerona3 air source heat pumps, Spira and Vecta biomass boilers, Sahara solar thermal collectors and VortexAir hybrid systems which combine an oil boiler with an air source heat pump.
Grant Error Codes
Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of error codes for all Grant Boilers to help you understand what’s wrong before you contact an engineer.
