Central heating isn't always the right answer. Perhaps you're converting a garage into a home office, adding warmth to a conservatory, heating a spare bedroom or replacing an old storage heater. In situations like these, an electric wall heater can be a simple and relatively affordable solution.

You might be here because:

• You want to heat one room without extending your central heating

• You're renovating a room that doesn't currently have a radiator

• You're comparing electric wall heaters with other electric heating options

• You want to understand the installation costs before choosing a heater

This guide explains how much electric wall heater installation costs, what affects the price, how much they cost to run and when it's worth hiring a qualified electrician.

How much does electric wall heater installation cost?

The total cost depends on whether you're supplying the heater yourself or paying for supply and installation together.

As a guide, professional installation costs around £150 on average, while a basic electric wall heater supplied and installed typically costs around £150.

Choosing a smart or programmable model increases the average supply and installation cost to around £400, although prices vary depending on the electrical work required and the heater you choose.

Budget reality check

Electric wall heaters are generally one of the more affordable fixed heating systems to install because they don't require pipework or changes to your central heating system.

However, if your chosen location needs a new electrical circuit, additional wiring or consumer unit upgrades, installation costs can rise.

Electric wall heater installation costs by type

Not every electric wall heater is designed for the same job. Some are intended as an affordable way to warm an occasionally used room, while others offer smart controls that make them better suited to everyday living spaces.

Basic electric wall heater

A basic electric wall heater is the most affordable option, with supply and installation typically costing £150–£550, averaging around £150.

Basic electric wall heaters are often a good choice for:

• Spare bedrooms

• Utility rooms

• Home offices

• Occasional top-up heating where you don't want to extend your central heating

Smart or programmable electric wall heater

Smart electric wall heaters cost more to buy but offer greater control over when and how your room is heated.

Expect to pay £250–£750 supplied and installed, with an average cost of around £400.

Smart or programmable electric heaters are particularly well suited to:

• Garden rooms

• Home offices used every day

• Kitchen extensions

• Living spaces where maintaining a comfortable temperature throughout the day is important

What affects electric wall heater installation costs?

Two installations can look very similar on paper but end up costing quite different amounts.

The heater itself is only one part of the project. Where it's being fitted and what electrical work is needed often has just as much influence on the final price.

• Type of heater: Basic wall heaters are generally quicker to install than smart models with advanced controls

• Electrical work required: If suitable wiring already exists nearby, installation is usually straightforward. Creating a new circuit or upgrading your consumer unit will increase labour costs

• Number of heaters: Installing several wall heaters during the same visit may reduce the average installation cost per unit

• Location: Installing a heater on a simple internal wall is generally quicker than fitting one in a more challenging location or where cable routes are difficult

• Labour rates: Electricians' hourly rates vary across the UK, with prices generally being higher in London and the South East

Additional costs to budget for

Installing an electric wall heater can sometimes uncover extra work that wasn't obvious at the start. Factoring these items into your budget early can help avoid surprises once work begins.

Depending on your home, you may also need to budget for:

• A new electrical circuit

• Consumer unit upgrades

• Additional wiring

• Making good walls after installation

• Decorating

• Smart controls or thermostats

Not every installation will require these, but they're worth discussing before work starts so you have a realistic picture of your overall project cost.

What should be included in a quote?

When comparing quotes, don't just look at the bottom line. A detailed quote makes it much easier to understand exactly what you're paying for and compare quotations fairly.

A clear quote should outline:

• Supply of the heater (if included)

• Installation labour

• Electrical testing

• Minor wiring and fittings

• Removal of packaging or old equipment (where agreed)

• VAT, where applicable

How long does electric wall heater installation take?

If the necessary wiring is already in place, many electric wall heaters can be installed within a couple of hours.

More complex installations involving new circuits, consumer unit upgrades or multiple heaters will naturally take longer.

A qualified electrician will be able to provide a more accurate timescale after assessing your property.

DIY vs professional electric wall heater installation

Portable plug-in wall heaters don't usually need professional installation. However, if your heater is hardwired into your home's electrical system, it's safest to use a qualified electrician.

Professional installation helps ensure your heater is correctly connected, safely tested and complies with current electrical regulations.

How to install an electric wall heater

The exact installation process will depend on the heater you've chosen, but it generally involves:

• Isolating the electrical supply

• Fixing the mounting bracket securely to the wall

• Connecting the electrical wiring in accordance with the manufacturer's instructions

• Mounting the heater

• Testing the heater to make sure it's operating safely and correctly

These steps are intended as a general overview only. Any hardwired electrical work should be carried out by a qualified electrician.

Are electric wall heaters expensive to run?

Electric wall heaters convert almost all the electricity they use into heat. However, because electricity is generally more expensive than mains gas, they're usually best suited to heating individual rooms rather than serving as the main heating system for an entire house.

Smart and programmable models can help reduce wasted energy by heating rooms only when you need them, making them a good option for home offices, spare bedrooms and other spaces that aren't used all day.

If you're comparing different electric heating systems, our guides to electric heating options and low-cost energy-efficient heaters explain how wall heaters compare with alternatives such as electric radiators, storage heaters and infrared heating.

Are electric wall heaters worth it?

If you're looking for an affordable way to heat a single room, an electric wall heater is often a good option.

Electric wall heaters are particularly useful where extending your central heating would be expensive or impractical, such as:

• Home offices

• Garden rooms

• Conservatories

• Loft conversions

• Spare bedrooms

They're generally less suitable as the primary heating system for a whole house, where central heating or other electric heating solutions may be more effective.

Electric wall heater installation checklist

• Decide which type of wall heater best suits the room

• Check whether your existing wiring is suitable

• Consider whether you want smart controls or programmable heating

• Ask if any additional electrical work is likely to be needed

• Compare a selection of itemised quotes from qualified electricians

• Confirm how long the installation is expected to take

When should you speak to an electrician?

It's worth speaking to an electrician before buying your wall heater if you're unsure whether your home's wiring is suitable or you're planning to heat a room that doesn't currently have fixed heating.

Getting advice early can help you choose the right heater, understand whether any additional electrical work is needed and budget more accurately before any work begins.

FAQs

How much does it cost to install an electric wall heater?

Professional installation typically costs £80–£400, with an average installation cost of around £150.

For both supply and installation together, expect to pay around £150 for a basic wall heater or £400 for a smart model on average.

Do electric wall heaters need their own circuit?

In many cases, electric wall heaters need their own circuit. Hardwired electric wall heaters usually require their own dedicated electrical circuit to ensure they operate safely. A qualified electrician can confirm what's needed for your chosen heater.

How much does an electric wall heater cost to run?

Running costs depend on the heater's wattage, how long it's used and your electricity tariff. Smart controls and programmable timers can help reduce energy use by heating a room only when needed.

Can I install an electric wall heater myself?

Portable plug-in models don't normally need professional installation. However, hardwired electric wall heaters should be installed by a qualified electrician to ensure they comply with current electrical regulations and are safe to use.

Are electric wall heaters worth it?

Electric wall heaters can be an excellent solution for heating individual rooms, particularly home offices, garden rooms and spare bedrooms. If you're heating an entire property, however, another heating system may be more suitable.

What's the difference between an electric wall heater and an electric radiator?

Electric wall heaters generally provide quick, direct heat and are often used as room-specific heating.

Electric radiators are designed to provide more consistent background heating and commonly include advanced controls that make them suitable for everyday use.
