Having the best radiators – and only the best – is a smart investment that will last for years. But with so many options and specifications to navigate, it can be tricky to know which model is right for your home.
Whether you prefer a wall-mounted or floor-standing design, radiators come in various sizes, colours, and power outputs to efficiently heat your home. While panel models are sleek and modern and can be bought as a double to boost heat output, column radiators are typically more traditional and can have a deeper width for more heat.
To help, we've included some advice from industry experts, applied our own knowledge and compared radiator spec to narrow down your search to just nine options. If you specifically want a new radiator for the bathroom, check out our guide to the best bathroom radiators, too.
The quick list
Short on time? Don't worry – we've put together a handy overview of the best radiators on our shortlist for a quick checkout, along with a way to jump down the page if you want more details.
This is the perfect radiator for those who are keen to install classic-style column radiators but are not so keen on the cost that usually comes with this type of radiator. Instead of cast iron, it is made from premium-quality steel.
If sleekness and subtlety are what you’re after in a radiator design, this one is a great option. Made from 1.5 mm premium mild steel, it’s perfect for areas of the home where you want to keep as much wall space free as possible. It’s also good value for money.
Radiators don’t need to be huge to deliver excellent heat output – and the Milano Aruba is a great example of this. Despite measuring just 400mm x 413mm, it still manages to provide a heat output of 1,170 BTU, plus other sizes are available in the range if you want a cohesive look throughout.
This radiator is one to consider if you want your heat source to make something of a style statement, without it overtaking the room it is fitted in. It has a high BTU rating of between 6,500–6,900 and comes in many different colours and sizes.
This is a great all-rounder that may not compete for the most exciting design on the market, but it offers a host of other advantages worth considering. Budget-friendly and ideal for smaller spaces, it is also lightweight, making it easy to install. This model measures 600 x 400 mm and has a heat output of 1,202 BTU.
If you thought electric radiators were old-fashioned and somewhat unsightly, then this model should see you reconsider. Just one of these Wi-Fi-enabled radiators can heat a 17 m² space and features a digital thermostat. Even better, it can simply be plugged in – no plumber required.

Flat panel radiators are a great option for those living in modern homes as they're sleek, unobtrusive and come in a range of contemporary colours. With its matt grey finish, it can be paired with a range of other sizes and configurations from the same range.
It can be really difficult to know what type of radiator to opt for in kitchens, where wall space is usually at a premium – but this stylish offering from NRG is well worth considering. The matt anthracite finish is really attractive, plus it is lightweight and easy to install too.
Electric oil-filled radiators are perfect for those times when you want a quick boost of heat without turning on your central heating. This white De’Longhi model is easy to move thanks to its large handles and delivers a heat output of 500 Watts.
The best radiator overall
There are plenty of reasons why the Milano Windsor Horizontal Double Column Radiator is our number one pick. It's the perfect choice for anyone looking to replicate the look of a traditional cast iron radiator – without the weight or price tag usually associated with column models.
The 1.5mm-thick, premium-quality steel construction ensures that heat is efficiently distributed through the columns and into your room, while the white powder-coated finish complements both traditional and classic contemporary interior schemes alike.
Another bonus of this radiator is that it can be combined with other models from the range for a cohesive look – including the tall vertical design (available on Amazon), which works well in awkward spaces. We can’t really think of anything negative to say, so it gets our vote for the best radiator you can buy.
The best contemporary radiator
This stylish radiator from NRG boasts a contemporary design that fits seamlessly with modern and minimalist home interiors.
Not only is it eye-catching, but it’s extremely durable too – made from 1.5mm premium mild steel with a high-quality white finish. It’s no surprise, therefore, that this model comes with a 15-year manufacturer’s guarantee.
Given its 180 x 35.4 x 7.8cm size (with multiple size options available), you certainly get great value for money, making it a smart choice for anyone planning a renovation or conversion on a budget. Brackets and fixings are included, but valves are not.
The best small radiator
The Milano Aruba comes in a variety of sizes, but we particularly love the 400 × 415mm model, which is smart, compact, and includes a blanking plug, bleed plug, and wall fixings. Made from extra-thick, low-carbon steel, the manufacturer is so confident in its durability that it comes with a 20-year guarantee.
Despite its dinky dimensions, it generates an impressive heat output of 1,170 BTU, making it ideal for small spaces, awkwardly shaped rooms, or for fitting neatly beneath window sills.
While it might cost a little more than some other compact radiators, it offers a sleek, contemporary appearance that more than makes up for the extra expense.
The best designer radiator
As the name suggests, this vertical radiator really is an elegant way to heat a room.
It’s an ideal option for awkward spaces and would look particularly stylish in a kitchen or hallway – both rooms where wall space is often at a premium. It’s available in single or double formats.
This is another radiator with a high BTU output (6,500–6,900), making it a strong choice for medium to large-sized rooms. Do make sure to get help lifting this one, though, as it’s a little heavier than some in the line-up, and its height and width can make it tricky for one person to carry.
It comes with wall brackets, a plug, and a vent, though valves need to be purchased separately.
The best budget-friendly radiator
While this compact radiator from Milano might not make the shortlist for its eye-catching good looks, it actually has quite a lot going for it. In fact, many people will be drawn to its ability to simply sit unnoticed within an interior scheme.
This is an excellent compact radiator for small spaces, measuring just 60 x 40cm. It’s lightweight too, meaning even relatively non-substantial walls can support it easily – plus, it delivers an impressive heat output of 1,202 BTU.
In short, this is an ideal radiator for anyone on a budget, whether you’re replacing old radiators as part of a heating system upgrade or starting from scratch.
The best electric radiator
The Devola Glass Panel Heater proves that electric radiators are anything but boring. It’s available in a choice of black, white, or grey finishes, as well as with alternative heat outputs. In this case, a single 1500W heater can warm a 17-square-metre room.
As well as looking smart, it is smart. Being Wi-Fi enabled, it allows you to control it from anywhere using your smartphone. It can be operated via voice assistants such as Alexa or Google Home, or through the dedicated app.
Another benefit of this radiator is how easy it is to install – use it as a freestanding unit or simply mount it on the wall. With either option, you’ll just need to ensure there’s an electrical socket within 1.5 metres. Its splash-proof design is IP24 rated, meaning you can even install it in a bathroom, although you’ll need to call in a qualified engineer if this is your chosen location.
The best flat panel model
Crisp and modern in form, and available in a wide range of sizes and configurations, this smart flat-panel radiator comes with all the brackets and fittings needed for installation (you’ll just need to purchase the valves).
This model is compatible with all UK heating systems, including tank-fed and combi setups, and reviewers were impressed by how quickly it warms up.
On the downside, this radiator is relatively heavy compared to some of the other models here (weighing 13.8kg), despite being made from 1.5mm premium mild steel. This will, of course, depend on the size you choose – but it’s something to keep in mind if you’re planning a DIY installation.
The best kitchen radiator
If you’re looking to minimise the amount of wall space taken up by your radiator, or are working with awkward areas – such as kitchens and bathrooms – this design would be a great choice.
Super sleek and contemporary in form, the matt anthracite finish makes a striking modern statement while remaining subtle enough to blend with a range of interior styles. Made from low-carbon steel, the radiator is also praised for its ease of installation.
However, it may not be the best option for those on a tight budget.
The best oil-filled radiator
Oil-filled radiators have increased in popularity over the last couple of years, with more of us working from home and keen not to turn on central heating when just one room needs warming rather than the whole house.
Oil-filled radiators work by using electricity to heat oil via an element inside a reservoir. When the element heats up, warmth is transferred to the oil, which then circulates through the appliance, warming its metallic panels.
The De'Longhi TRNS0505M Oil-Filled Radiator is a great model to consider. It is easy to move around the house thanks to its large, sturdy handles and lightweight design. However, it's worth bearing in mind that it doesn't have any wheels.
Its light modern white finish and subtle styling make it one of the better-looking offerings on the market, and it delivers an impressive heat output (500 Watts) – plus it heats up very quickly. This model can heat a space of up to 15 cubic meters and has been praised for being quieter than other oil-filled radiators on the market.
How to choose the best radiator
There are several factors to consider when choosing radiators which go beyond just setting a budget.
1. Calculate the BTU (British Thermal Unit):
“All radiators have a specified heat output so once you know how much heat the room needs you can choose the type, size and style to suit your taste and the room,” says energy-efficiency expert Tim Pullen.
Online BTU calculators (see manufacturers’ and suppliers’ websites) will help to give an indication of the output. Factors considered include; room dimensions, size of window openings and number of external walls present. For more information, read our guide that answers what are BTUs.
2. Measure up:
The size of radiator can impact the heat output, and you'll find that some manufacturers offer different sizes in their radiator designs. If, however, you’re stuck for space or simply prefer to be without radiators, skirting board heating is a discreet, space-saving alternative.
3. Consider the location, weight and preferred eco-credentials:
Colours and materials can also vary between radiators so you'll need to consider these three things. Steel or cast iron radiators are mega heavy so consider the wall type they will be mounted on, and who will be installing a radiator.
“Aluminum options are usually the most effective in terms of efficiency and they are the ‘greenest’ in terms of their manufacture,” explains Dave Thornback, UK Sales Manager at Vasco. “Added to the fact that they can be completely recycled at the end of their life.”
4. Choose your design:
You can have a lot of fun choosing the size and shape of a rad, but just be mindful to ensure you're going to be achieving the desired heat output for the space.
5. Set a budget:
After considering all this you can narrow down you search and set a budget, or think about how much you are prepared to pay. The cost of radiators can run into the thousands-of-pounds so it would be prudent to weigh up all of the factors above with how many new radiators you need, before heading to the check out.

Design and budget are foremost factors, but in order to choose the best radiator for your room, you will need to determine the heat requirements of the space.
Room sizes, window dimensions and even the materials used in the walls will all be used to calculate the required outputs of the radiators you will need to heat the room properly.
You will notice that radiators have a 'BTU rating'. BTUs are ‘British Thermal Units’ and this is the unit in which radiator efficiency is measured.
A heating engineer or plumber should be able to work this out for you, or you could use an online BTU calculator.

Electric vs plumbed-in radiators: Which is best?
Before you begin your search, decide whether you will need electric radiators or those that are plumbed in.
Electric radiators use mains electricity. Some are designed to be plugged into a socket, while others will need to be fitted by an electrician. You might also see infrared electric radiators for sale. These are good for small spaces as they have a high heat output with a slim profile.
Plumbed-in radiators are connected to your boiler and use hot water as their heat source. They’re controlled as part of the central heating system.
What are the different radiator types?
Here are the most common types of radiator and what they do:
- Side panel radiator: These basic horizontal radiators run off the central heating and are wall mounted.
- Double panel radiator: Made up of two single panel radiators, these are also wall mounted but have a greater heat output.
- Column radiator: A great way to add some character and charm to a home, while also providing warmth. They take up more space than panel radiators, but offer good heat output.
- Vertical radiator: If you're heating a more "creative" space then a vertical radiator is an option. They can also be known as "upright radiators" which are tall and narrow, making a great design statement.
- Heated towel rails: These are designed for drying and heating towels, geared towards being located in the bathroom. They can either run off the central heating or the electrics.
