New and Additional Radiator Installation

If one room is colder than the rest of your property, you may need an additional radiator installation or a better-positioned heat source.

We install new radiators where there is no existing radiator and can add a new radiator to an existing central heating system.

This is useful when extending your home, converting unused space, changing a room layout or improving heating in a room that has never had a radiator.

We also carry out radiator replacement when an existing radiator is damaged, corroded, underperforming or no longer suitable for the room.

Depending on the property, the existing pipework may be suitable to reuse, or it may need to be extended or altered for the new radiator.

Before starting the radiator installation, we check the existing heating system and pipework so the new radiator is installed properly and works as it should. If you need a new radiator fitted or want to add a new radiator to your home.

 Trustindex verifies that the original source of the review is Google. Rapid response from Armand to a Google Local Services request. Good comms via WhatsApp. Same day attendance. I live in a tricky area for parking but Armand managed that without complaint. Quickly diagnosed and resolved the problem with my heating system, made efficiency improvements, and taught me a few things along the way for future reference. The following morning I had a worsening situation due to air and pressure changes settling in the system overnight (unavoidable) but Armand was responding to my messages from 6:51am and helping me to relay instructions to my tenant in real time to apply a final fix. The heating system is now working incredibly effectively and efficiently. I'm burning hardly any gas to keep the property warm. Gas bill reducing substantially now. As with everything these days, skilled people don't come cheap; you get what you pay for and I would recommend Armand to others.

 Trustindex verifies that the original source of the review is Yell. Armand arrived the same morning as I called, keeping me informed as to his expected arrival time. He was very efficient at sorting the problem, which was stopped a leaking pipe. He wore a medical mask and gloves , and was very aware of social distancing and of not touching surfaces unnecessarily, enabling my lodger to remain safely at work in the same room whilst he was there. He is very polite and friendly and gives a clear explanation of what needs doing. He is my go-to person whenever I need a plumber, having been here three times now, and I highly recommend him .

Adding a Radiator to an Existing Heating System

Adding another radiator is often possible without replacing the whole heating system. However, the existing installation needs to be checked first to make sure the new radiator can be supplied properly.

When you want to add a new radiator, we will check:

This is particularly important in older properties, where pipework may not have been installed with future radiator additions in mind.

Simply fitting a larger radiator in a cold room will not fix the problem if the existing pipework cannot supply enough heat.

Likewise, adding another radiator to a system that is already struggling can reduce heating performance elsewhere in the property.

We check the system first, work out what is required and then carry out the additional radiator installation properly.

If you need another radiator installed, contact us and we can assess the existing system and advise on the right installation.

Our Radiator Installation Service

Every radiator installation is slightly different, depending on the property, heating system and where the new radiator needs to go. We check what is already there first, then carry out the work needed to get the new radiator installed and working properly.

Depending on the job, we can:

Check the radiator position
Check existing pipework
Assess the heating system
Size the new radiator
Extend or alter pipework
Install the radiator and valves
Refill and pressurise the system
Check for leaks
Test the radiator and heating system

If you are replacing an existing radiator and the pipework and connections are suitable, the job can be relatively straightforward. If you want to add a new radiator, the work may involve extending the heating circuit and running pipework to the new position.

We handle the installation from the initial assessment through to testing, so you have a radiator that is properly connected and heating the room as it should.

Call us now.

Radiators for Extensions, Renovations and Cold Rooms

A new radiator installation is often needed when a property has been extended, renovated or the way a room is used has changed.

You may need to add a new radiator to a new extension, loft conversion or home office, or replace an existing radiator that is too small to heat the room properly.

If a renovation has changed the layout, installing a radiator in a new position may also be the better option.

Whatever the reason, the new radiator needs to work properly with the existing heating system.

We check the available pipework, radiator position and required heat output before starting the installation.

This is especially important in older London properties, where extending existing pipework can be more involved than expected.

We assess what is already there, determine what needs changing and carry out the radiator installation accordingly.

Give us a call now for a proper radiator installation.

FAQ:

How much does it cost to have a radiator installed?

The cost of radiator installation depends on several factors, including the type and size of the radiator, whether new pipework is required, the location of the installation, the condition of your existing heating system, and whether you’re replacing an old radiator or installing a new radiator in a completely new position.

Every property is different, so the cost can vary significantly depending on the complexity of the work. If you’re looking for professional radiator installation London services, give our team a call. We’ll discuss your requirements and arrange a suitable appointment to assess the work needed.

Can I install new radiators myself?

Although it may seem like a manageable DIY project, installing new radiators is a specialist job that requires experience and the correct tools. The heating system needs to be safely isolated, pipework must be accurately measured and connected, the radiator securely mounted, and the entire system refilled, pressurised, balanced, and tested for leaks.

Incorrect installation can result in water damage, poor heating performance, pressure issues, corrosion, or expensive repairs to your central heating system. If you’re planning to install a new radiator, it’s always best to leave the work to a qualified heating engineer. Call our team to ensure the installation is completed safely, efficiently, and to the highest standard.

How do you install a radiator?

A professional new radiator installation begins by selecting the correct radiator size for the room and ensuring the existing heating system can support it. The installer will isolate and drain the system if necessary, fit or adjust the pipework, securely mount the radiator, connect the valves, refill the system, bleed the radiator, balance the heating system, and carry out comprehensive leak and performance checks.

Every installation should be completed carefully to ensure maximum heating efficiency and long-term reliability. If you’re planning a radiator installation, call our experienced engineers to arrange a professional installation carried out with minimal disruption.

How do you install a home radiator?

Installing a home radiator involves much more than simply fixing it to the wall. The correct location, radiator output, pipework layout, valve selection, and heating system balance all need to be considered to ensure the radiator performs efficiently and heats the room properly.

Whether you’re upgrading an old unit or installing a new radiator as part of a renovation, professional installation helps prevent future leaks, uneven heating, and unnecessary strain on your boiler. If you’re considering a radiator installation London service, give us a call to arrange an appointment with one of our experienced heating engineers.

Do I need a plumber to install my radiator?

No. Hiring a plumber for a job of a heating engineer is not recommended, especially for a radiator installation.

It needs good knowledge of central heating systems, how radiators work, and a Gas Safe Certificate, which a plumber simly doesn’t have.

As Gas Safe engineers in London we will ensure the radiator is correctly positioned, securely connected, properly balanced, and thoroughly tested before the heating system is returned to service.

Professional installation also helps protect your boiler and central heating system while ensuring your new radiator performs efficiently for years to come. If you need to install a new radiator, call our team to arrange a reliable and professional installation.

Where can I find a reliable radiator installer near me?

Choosing an experienced heating engineer is the best way to ensure your radiator is installed safely and performs efficiently. When searching for a radiator installer near me or radiator installation near me, look for a company with proven experience, excellent customer reviews, and expertise in all types of domestic heating systems.

Our engineers carry out professional radiator installation London services, whether you’re replacing a single radiator or installing new radiators throughout your property. We can also help if your existing radiator valves need attention before installation checkour Radiator Valve Repair service if the valve can be repaired, or our Radiator Valve Replacement page if a new valve is required. Call our team to book an appointment and we’ll ensure your installation is completed to the highest standard
