Can I Install Electric Radiators Myself? Your Guide to Electric Radiator Installation

Last Updated on 6 May 2026 by Howard Klineberg

Are you looking at making the switch to electric heating and wondering whether electric radiator installation is a realistic DIY project? You are not alone. A lot of homeowners are asking the same question as they look to reduce their carbon footprint and move away from gas. While there are a number of “plug and play” products that make a DIY electric radiator installation possible, having a registered engineer is essential for a lot of electrical work.

We urge customers to always choose the best electric radiators for their home based on performance, functionality and efficiency, not just convenience.

As this is what’s going to save you money in the long run. If you want to know the different options available, read our guide on how to install an electric radiator yourself, which products can be installed without an engineer, and what the drawbacks are.

Can I Install Electric Radiators Myself as a DIY Project?

Yes, you can install some electric radiators yourself if you choose plug-and-play models that require just a standard socket and wall mounting, but this approach has significant limitations for whole-home heating and long-term efficiency.

Due to the rise in DIY electric radiators on the market, a lot of homeowners are now asking, “Can I install electric radiators myself?” To answer your question, it very much depends on the type of radiator you buy. There are certain electric radiators which just need to be plugged into a socket. They usually come with a wall mounting kit, so you can mount them yourself. These radiators can be a good short-term solution if you just need it for one room in the home. You also don’t need to have a great deal of experience to know how to install an electric radiator that just plugs in. However, there are a number of drawbacks when it comes to heating multiple rooms in the home.

Taking up plug sockets is often the first frustration. Instead of being hardwired, these DIY radiators use up power sockets around the home, so there are less for appliances and other electrical items. Wires are on display too, because without hardwiring, plug and play radiators leave unsightly wires in view. You are also limiting your efficiency. If you restrict yourself to products that allow DIY electric radiator installation, you may not be choosing the most energy-efficient model on the market. Finally, power issues can arise. If you need to deck out your whole house, hardwiring will be necessary. Too many electric heaters connected to one ring main can overload it, causing the fuse box to trip.

Why Do I Need Professional Electric Radiator Installation?

Professional electric radiator installation ensures your new heating system is hardwired safely into the wall, eliminates visible wiring, frees up your plug sockets, and allows you to choose the most efficient products on the market without compromise.

When it comes to electric radiators that require hardwiring, it’s important to have them installed by an experienced engineer. Professionals ensure that radiators are installed in a safe way, are fully functional, and are able to perform in the most energy-efficient way. The benefits of a hardwired finish are immediately clear. Electricians run any wires through the wall to reach the fused spur, meaning the finished look is clean and seamless. Your plug sockets remain free for other appliances, rather than being permanently occupied by heaters. Most importantly, having a radiator installed by a professional means that your radiators are safe and correctly integrated into your home’s electrical system. Choosing professional installation also means you are not limiting yourself to products with DIY electric radiator installation, so you can find the most environmentally-friendly options, such as radTherm radiators.

What Makes radTherm Radiators 100% Efficient?

radTherm electric radiators promise 100% efficiency by converting every single watt of electricity drawn from the wall directly into usable heat for your home, unlike gas central heating systems which can lose a significant amount of energy through pipework and the boiler itself.

Customers could save up to a third on their energy bills with modern, high-efficiency electric radiators compared to older heating systems (Energy Saving Trust). These electric radiators reach operating temperature in minutes because there is zero energy wastage. While gas central heating systems typically lose heat in the distribution process (research suggests that insulating pipes can reduce losses, but uninsulated systems are far less efficient, as noted by the Energy Saving Trust), radTherm electric radiators convert all energy into heat for the room. They also come with stress-free installation, with no pipework and no maintenance. One of the most frequently asked questions for the radTherm product is “Can I install radiators myself at home?” These radiators must be installed by a certified radTherm engineer. The good news is that we provide a complete turnkey installation that includes the removal and disposal of your old heating system, all associated electrical work and full installation. Plus, we provide an aftercare service for customers, with a 24-hour response on any faults.

How Quickly Can Electric Radiator Installation Be Completed?

In the vast majority of homes, our team can complete the full electric radiator installation in just one day, removing your old system and leaving the house clean, warm, and fully functional with no disruptive pipework changes.

We install radiators with very little disruption to your home too, and can usually get everything up and running on the same day. No mess, no muddy boots, and a clean home just as you left it once we’re all done. This speed is possible because no central heating pipework is required. Each radiator is a sealed, independent unit that simply needs fixing to the wall and connecting to a fused spur. The process is radically simpler than a gas boiler replacement.

Can I Upgrade My Hot Water System at the Same Time?

Absolutely, and combining your electric radiator installation with a modern hot water battery can dramatically reduce the overall energy you use for heating water, potentially saving up to 75% on your water heating bills annually.

At North East Heating Solutions, we can also upgrade your hot water system to a highly efficient solution like the Sunamp heat battery. This system stores heat directly and releases it instantly for hot water, sidestepping the standing losses you get with a traditional hot water cylinder. Independent research on modern heat storage for domestic hot water shows that systems moving away from constant cycling losses can achieve dramatic energy reductions (Hot Water Association). To learn why this might be the perfect time to upgrade your hot water system, read our full guide. By pairing a modern electric radiator system with an efficient water heating setup, you maximise your long-term savings and cut your carbon footprint decisively.

What Should I Consider Before Choosing an Electric Radiator?

Before you make a purchase, think carefully about what each room actually needs. A common mistake is simply matching the old gas radiator sizes. Electric radiators behave differently because they are responsive, fast, and do not rely on a central boiler cycling on and off. You need to calculate the precise heat loss for the room, considering window size, insulation levels, and ceiling height. Our team carries out this room-by-room survey as standard during the quote process to ensure your system is sized correctly. Making the right decisions at this stage is what unlocks the long-term savings and keeps your home at a consistently comfortable temperature without wasting energy.

Frequently Asked Questions

Do electric radiators require ongoing maintenance?

No, one of the major advantages of modern electric radiators is that they are virtually maintenance free. Because there is no central boiler, no pump, and no water-filled pipework to leak or corrode, the annual servicing requirement associated with gas boilers disappears entirely. An occasional wipe down to keep dust off the surface and a periodic visual check of the power cable is all that is needed.

Are electric radiators safe to leave on overnight?

Yes, modern hardwired electric radiators are extremely safe to leave on overnight, provided they have been professionally installed with an appropriate fused spur connection. They feature built-in thermostatic controls that prevent overheating, and since they do not burn fuel or emit fumes, there is zero risk of carbon monoxide poisoning compared to older fossil fuel systems.

Can I install an electric radiator in a bathroom?

You can, but you must follow strict electrical safety regulations for wet zones. Bathroom electric radiator installation requires a suitably IP-rated (Ingress Protection) radiator that is safe for use in zones where it might be exposed to water spray. Any hardwiring work in a bathroom must be carried out by a qualified electrician to comply with Part P of the Building Regulations.

How do I choose the correct size electric radiator for my room?

The correct size is determined by an accurate room heat loss calculation, not just by matching the dimensions of your old radiator. Factors like room dimensions, the number of external walls, window type, and insulation levels are all fed into a heat loss calculation to give the precise wattage required. Professional installers use this data to recommend a correctly sized radiator that warms the space efficiently without wasting electricity.

Will switching to electric radiators increase my carbon footprint?

If you are moving away from a gas boiler, your carbon footprint will decrease over time because the UK electricity grid is rapidly decarbonising. According to the National Grid ESO, zero carbon sources regularly supply the majority of the country’s electricity. Electric radiators at the point of use produce no direct emissions, making them cleaner than burning gas inside your home now and even cleaner as the grid gets greener each year.
