- Awkward pipework: up to about £600
- Extensive rerouting, chasing pipes into walls or system work can cost much more
We didn't find a Leicestershire-specific figure. Guides put central London 20% to 40% above the UK average, and the East Midlands generally sits around average.
What's included in a like-for-like swap
- Draining down the system, or isolating and draining the radiator
- Removing the old radiator
- Fitting new brackets and the new radiator
- New valves if needed (often recommended)
- Refilling, bleeding and checking for leaks
- Adding inhibitor to protect the system
What pushes the price up
A different size or style
If the new radiator's pipe centres don't match the old one, the pipework has to be altered. Vertical, column and designer radiators are heavier and often need different brackets and pipe positions.
Moving it
Moving a radiator to another wall means new pipe runs. With suspended timber floors this is easier. With solid floors, pipes may need chasing into walls or running in boxing.
New valves
Thermostatic radiator valves (TRVs) give better room-by-room control. Adding them to several radiators adds parts and time.
The state of your system
Sludge in the old radiators, corroded valves or a system that's never had inhibitor may lead your plumber to suggest flushing or balancing. Checkatrade notes that balancing and power flushing are common add-ons that raise the final bill.
Plastering and decorating
Moving a radiator can leave holes and marks. If pipes are chased in, you'll need a plasterer. See our plasterers page.
Gas Safe: when it matters
Swapping a radiator is wet central heating work, not gas work, so it doesn't legally need a Gas Safe engineer. But if the job involves any work on your gas boiler (for example adjusting, relocating or replacing it), that part must be done by a Gas Safe registered engineer. Many heating engineers are both. Our guide plumber or gas engineer? explains the difference.
If you ever smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999.
How long does it take?
A like-for-like radiator swap usually takes about two hours. Several radiators in one visit is more efficient, because the system only needs draining and refilling once. Moving a radiator typically takes two to five hours.
Good times to replace radiators
- During a renovation, before plastering and flooring, when pipes are easy to reach
- Before winter, rather than in a cold snap when plumbers are busiest
- Alongside a boiler change, when the system is being drained anyway (gas work by a Gas Safe engineer)
Hard water can contribute to scale in heating systems over time. Market Harborough is supplied by Severn Trent Water, and local data puts LE16 in the hard range. See hard water in Market Harborough.

Questions to ask
- Does the price include the radiator, valves and inhibitor?
- Will you drain the whole system or just isolate the radiator?
- Will the pipework need altering for the new size?
- Do you recommend flushing the system, and why?
- Are you Gas Safe registered, if any boiler work is involved?
- Is there a guarantee against leaks?

Choosing the right size radiator
A new radiator that looks right but is too small will leave a room cold. Heat output is usually given in watts or BTUs on the product page. A plumber or heating engineer can work out roughly what each room needs from its size, windows, outside walls and insulation.
A few practical tips:
- Measure the pipe centres of your existing radiator (the distance between where the two pipes come up). Matching it keeps a swap simple.
- Don't just match the old radiator. If a room was always chilly, the old one may have been undersized.
- Check the wall. Heavy cast iron or tall vertical radiators need a solid wall or proper fixings into stud work.
- Think about furniture. A radiator behind a sofa loses a lot of its heat into the back of the sofa.
- Planning a heat pump in future? Heat pumps run at lower water temperatures, so radiators often need to be larger. Mention it to your plumber so you don't buy twice.
If you're replacing several radiators, it's worth asking for the whole house to be looked at together.

Frequently asked questions
How much does it cost to replace a radiator in 2026?
Most 2026 UK guides put a like-for-like radiator replacement at roughly £150 to £450 per radiator including a standard unit, according to Rated People. Labour alone is around £150 to £300 outside London. Designer, column and vertical radiators cost more, as does any change to the pipework. Your exact price comes from a plumber's quote.
How much does it cost to move a radiator?
A simple radiator move typically costs around £150 to £350, with MyJobQuote giving an average of about £220 for two to five hours' work. Awkward pipework can take it to about £600, and extensive rerouting or chasing pipes into walls can cost more. You may also need some plastering and decorating afterwards.
Do you need a Gas Safe engineer to change a radiator?
No. Replacing a radiator is work on the wet central heating system, not gas work, so a competent plumber can do it. However, any work on the gas boiler itself, such as adjusting, moving or replacing it, must by law be done by a Gas Safe registered engineer. Many heating engineers hold both skills.
How long does it take to replace a radiator?
A straightforward like-for-like radiator swap usually takes about two hours, including draining, fitting, refilling and bleeding. Doing several radiators in one visit is more efficient, because the system only needs draining and refilling once. Moving a radiator to a new position typically takes two to five hours.
Should I replace radiator valves at the same time?
It is often worth it. Old valves can seize or weep, and replacing them while the radiator is off is cheaper than doing it later. Thermostatic radiator valves (TRVs) let you control each room's temperature, which can help comfort and running costs. Ask your plumber to price valves separately so you can decide.
