Fitting a new radiator is not the most difficult of tasks and any competent plumber with experience of central heating systems should be able to do this work.
But how much is the going rate for this type of job? How long does it take and will your boiler be able to cope with a new radiator added to the system?
Don’t forget: this is just of many price guides we have, so join the many thousands of other people who have saved money and go explore our full price list here.
There are several reasons why you would want to add a radiator to your system.
Here are the most common:
- to swap a single radiator for a double
- to add an extra radiator to a room
- to relocate an existing radiator
- to swap a standard radiator in the bathroom for a vertical heated towel rail
Before you proceed with installing an additional radiator, our friend Tony has some advice:
In the winter I often get phone calls from homeowners looking to replace a radiator with a larger one because their house is too cold. In many cases a quick temperature check of the existing radiators shows they are not working efficiently and this can usually be rectified by a powerflush of the system to remove any blockages. If your room is too cold, I would first suggest having your system checked by a profesisonal who can then suggest a course of action. That could be a powerflush, an additional radiator or both.
The Next Step: Choose the Best Radiator by Calculating the Heat Output
Not all radiators are the same.
Some will have a lower heat output than others.
Fortunately, there is a system in place that allows you to easily calculate the amount of heat each room in your house requires to stay comfortably warm.
All you need to do is calculate the BTU (British Thermal Unit). Don’t worry, this isn’t a difficult or time-consuming process.
In fact; it’s incredibly easy!
Because all radiators are rated in BTUs, once you have this figure, you can choose the best radiator to suit your room size.
There are many factors that need to be taken into account when calculating the BTU for your room. The size of the room, how many external walls it has, how many square metres of glazing the room has etc.
To save time and to keep things simple, we suggest you use this very handy BTU calculator to calculate the heating needs of your room and then select a radiator that matches or exceeds your requirements.
How Much Do YOU Think a Newly Installed Radiator Will Be?
This may seem a strange question, after all, you have visited our page to discover this answer.
We are however doing research into how much homeowners think certain home improvement projects will set them back.
The question below is optional and you can skip it if you wish (although we would like you to answer)
Hopefully by now you will know the BTU and thus what type of radiator that will best suit your room, it’s now time to look at prices and charges.
We will now explore the following:
- cost for a new radiator
- cost of piping and making good the walls
- extras you may want
- labour charges
With all of the above costed, you can easily see the going rate for a plumber to install a new radiator.
We can even point you in the right direction so you can get a written quote.
Typical Price to Buy and Install a Radiator
The average cost of a radiator is detailed below.
These are all typical prices and assume an average sized room:
Living room radiator – £100(budget range) £300(premium range)
Bedroom radiator – £65(budget range) £250(premium range)
Bathroom heated towel rail – £50(budget range) £120(premium range)
The cost of piping is negligible but you’ll probably want to purchase a TRV (thermostatic radiator valve) so you can adjust the heat of the radiator.
Thermostatic valves cost around £15 for a good quality one.
Below is Our Installation Price Guide
Below you can find our guide price for the purchase and installation of a new radiator.
We’ll assume the radiator costs £100 and the room is upstairs on the first floor of a house with gas central heating.
- check the output of the existing heating system and confirm that it can cope with an additional radiator
- lift carpets or floorboards and located existing pipework
- drain system
- extend pipework to the desired location
- secure radiator bracket to wall and hang the radiator, connect to pipework
- connect TRV
- refill system and fire up the heating to full power and test the heat output of each radiator in the house
- re-lay carpets/flooring and make good any minor repairs to walls with plaster (to be painted/decorated by customer)
- dispose of any waste material
|Pipe, connectors, parts etc||£25.00|
How to Save Money
As you can see from the table above, we have made an allowance for VAT and the profit margins a company would be looking to make for a job such as this.
You can, of course, make a saving by choosing a smaller business to fit your radiator for you.
There are many plumbers that are self-employed and charge enough to cover their wages, fuel and the few overheads they have.
Most smaller firms are also trading below the VAT registration threshold so you don’t need to pay this tax either. We have more info about how you can avoid paying VAT (legally) on this page.
We have created a guide to tradesperson’s day rates in the UK, it’s a great read and very insightful:
Should You Powerflush The Heating System?
Central heating systems often get clogged with scale and sludge.
This can result in cold spots on radiators which can only be compensated for by increasing the thermostat temperature and keeping the system switched on for longer.
This obviously costs you more money.
Plumbers and central heating engineers recommend powerflushing when:
- a new boiler is fitted
- any substantial work is carried out such as new radiators
- every 15 years
If you are considering having additional or larger radiators installed because your house is too cold in the winter, then we suggest you first have the temperature of the radiators checked.
You might be able to fix any issues without installing a new radiator.
How Many Extra Radiators Can I Add to My System?
This will depend on your existing boiler and pump.
Most systems, even those that a many years old, can cope with upgrading the size of a radiator or two.
But if you are adding entirely new radiators to the system, perhaps due to a loft conversion or extension, then you really should calculate the requirements of your all your radiators and check if your boiler can cope.
If it can’t and you have exceeded the maximum number of radiators, then excess pressure will be put on the system.
This can result in an inefficient central heating system and premature failure of some parts, such as the pump.
