How Much Does a Plumber Charge to Change a Radiator?

If you're considering replacing a radiator in your home, you might be wondering how much a plumber will charge for the job. The cost can vary depending on several factors, such as the size of the radiator, the complexity of the installation, and your location.

In this guide, we'll break down the costs involved, what affects the price, and whether you should attempt the job yourself or hire a professional.

Average Cost to Replace a Radiator

In the UK, the cost to change a radiator typically falls between £175 and £450, including labour. However, this is just a general estimate, and the final price can be influenced by various factors.

Here's a breakdown of typical costs:

• Labour cost – A plumber usually charges between £50 and £110 per hour. A straightforward swap of an old radiator for a new one takes around 1-2 hours, depending on accessibility and pipework adjustments.

• Cost of the radiator – Standard radiators range from £50 to £200, while designer or vertical radiators can cost upwards of £400.

• Additional materials – New valves, brackets, or pipe extensions may add £20 to £60 to the total cost.

Our Prices

At Kesselmann, our pricing is as follows:

• A like-for-like standard convector radiator replacement typically takes 1-2 hours, costing £80-£160 for labour.

• If the job entails changing the radiator style (e.g., replacing a conventional radiator with a column radiator), it could take 2-4 hours due to required pipework alterations, costing £160-£320 for labour.

• If a drain down of the heating system is necessary, an inhibitor will be required, adding to the cost.

• For larger, heavier radiators, two people may be required to lift and install it, which can further influence the final price.

Factors That Affect the Cost

1. Size and Type of Radiator

Larger and more complex radiators take longer to install and may require additional work, such as reinforcing the wall or adjusting pipework. Standard panel radiators are more affordable to replace than designer or cast-iron models.

2. Pipework Adjustments

If your new radiator is a different size than your old one, the plumber may need to extend or reroute the pipework. This can increase the time and cost of the job.

3. Condition of Your Heating System

If your system is old or has been poorly maintained, the plumber might need to flush the system or replace additional components, such as radiator valves. A power flush can add an extra £500 to £800 to the cost.

4. Location

Plumbers in London and the South East tend to charge higher rates than those in other parts of the UK. If you live in a remote area, you might also have to pay extra for travel costs.

5. Number of Radiators

If you're replacing multiple radiators at once, you might be able to negotiate a lower price per unit, as the plumber can complete the job more efficiently.

How Long Does It Take to Change a Radiator?

A simple like-for-like radiator swap usually takes between 2-4 hours. If pipework adjustments are needed, the job can take 4-6 hours or more. If additional work is required, such as a system flush or upgrading valves, the job could extend to a full day.

Can You Change a Radiator Yourself?

If you're confident with DIY plumbing, you might be able to change a radiator yourself, saving on labour costs. However, you should be aware of potential risks:

• Water Leaks – If the radiator isn’t fitted correctly, you could end up with leaks that cause damage to your home.

• Bleeding and Balancing – You'll need to correctly bleed and balance the system to ensure even heat distribution.

• Complex Pipework Adjustments – If the pipework needs altering, it’s best left to a professional.

• Warranty Issues – If something goes wrong, you won’t have the reassurance of a qualified plumber’s guarantee.

For a simple like-for-like swap, a confident DIYer might be able to complete the job in a few hours. However, for more complex installations, hiring a professional is the safest option.

Additional Costs to Consider

1. Upgrading to Thermostatic Radiator Valves (TRVs)

TRVs allow you to control the temperature of individual radiators, improving efficiency. Upgrading to TRVs can add £12 to £30 per valve, plus labour.

2. Wall Reinforcement

If you're installing a heavier radiator, you may need additional brackets or wall reinforcement, which could cost £50 to £100.

3. Power Flushing the System

If your heating system has sludge buildup, a power flush may be necessary. This can add £500 to £800 but helps improve heating efficiency.

4. Removing and Disposing of the Old Radiator

Some plumbers include this in their price, but others may charge an additional £20 to £50 for disposal.

How to Find a Reliable Plumber

When hiring a plumber, it’s important to choose a qualified and reputable professional. Here are some tips:

• Check Reviews – Look at online reviews on Google, Trustpilot, or Checkatrade.

• Get Multiple Quotes – Always compare at least three quotes to get a fair price.

• Ensure They Are Gas Safe Registered – If any boiler or central heating work is involved, the plumber must be Gas Safe registered.

• Ask About Guarantees – A good plumber will offer a guarantee on their work.

Conclusion

The cost to change a radiator in the UK typically ranges from £175 to £400, depending on factors like radiator size, pipework adjustments, and location. While DIY replacement is possible for experienced homeowners, hiring a professional plumber ensures the job is done correctly and safely.

If you're looking to replace a radiator, it's best to get multiple quotes, check credentials, and factor in any additional costs such as valve upgrades or system flushing. Investing in a professional installation can save you from potential headaches and costly repairs down the line.
