TL;DR — Radiator Replacement Cost At A Glance
- Like-for-like labour is usually £150–£300 outside London and £200–£400 in London to swap a radiator in the same position.
- The radiator itself costs £50–£1,000+ — a single panel starts around £50, while designer and column radiators reach £150–£600+.
- All-in, a straightforward radiator replacement typically lands around £250–£1,000, depending on the radiator you choose.
- Cost drivers are the radiator type and size, whether it's a like-for-like swap or a repositioning, draining the system and your location.
- Repositioning or upsizing a radiator costs more because it means new pipework and, sometimes, rebalancing the system.
- Booking a radiator swap alongside other heating work — or at the same time as a boiler service — spreads the call-out and saves money.
- Get a fixed price to replace a radiator — check prices and book online or arrange a visit that suits you.
How Much Does Radiator Replacement Cost In 2026?
Replacing a radiator like-for-like costs £150–£300 in labour across most of the UK, rising to £200–£400 in London and the South East. Add the radiator itself — anywhere from £50 to £1,000+ — and all-in costs usually land between £250 and £1,000, depending on the type and size you choose.
A like-for-like swap in the same position is the low-cost scenario: the plumber isolates or drains the system, removes the old radiator, hangs the new one on the existing brackets and pipework, then refills and bleeds it. Costs rise when the radiator is larger (needing new brackets and, sometimes, bigger valves) or repositioned (needing new pipework run under the floor or across the wall). The state of the wider central heating system matters too — an old system may need draining and rebalancing, which adds time.
Here is what you can expect to pay to replace a radiator, by type:
| Radiator type | Rest of UK (all-in) | London & South East (all-in) |
|---|---|---|
| Single panel radiator | £120 – £240 | £150 – £300 |
| Double panel radiator | £160 – £320 | £200 – £400 |
| Towel radiator | £150 – £300 | £180 – £360 |
| Column radiator | £200 – £500 | £250 – £600 |
| Vertical radiator | £200 – £500 | £250 – £600 |
| Designer / statement radiator | £250 – £700+ | £300 – £800+ |

Radiator Replacement Cost Breakdown: The Radiator Itself
The radiator is a separate cost from the labour, and the type and style make a big difference:
| Radiator type | Typical unit price (inc VAT) |
|---|---|
| Single panel radiator | £50 – £150 |
| Double panel radiator | £80 – £250 |
| Towel radiator | £50 – £250 |
| Column radiator | £100 – £500+ |
| Vertical radiator | £100 – £400 |
| Designer / statement radiator | £150 – £600+ |
Standard single and double panel radiators are the most affordable and the most common. Towel radiators suit bathrooms; vertical and column radiators are chosen where wall space is tight or for their looks; and designer radiators sit at the top of the range. Add the unit to a like-for-like labour cost of £150–£300 (£200–£400 in London) and most homeowners spend between £250 and £1,000 in total. New valves — including thermostatic radiator valves (TRVs) — are a small extra that is often worth adding at the same time.
Check Prices & Availability
What Affects The Cost Of Replacing A Radiator?
Several factors decide where you land in the ranges above.
1. The Radiator Type And Size
A single panel radiator is the cheapest to buy and hang. Double panel, column, vertical and designer radiators cost more, and larger units are heavier and may need stronger brackets and larger valves.
2. Like-For-Like Vs Repositioning
Swapping a radiator for one of the same size on the existing pipework is the cheapest job. Moving the radiator to a different wall, or fitting a much larger one, means new pipework and more labour.
3. Draining And Refilling The System
A like-for-like swap can often be done by isolating the radiator alone. If the system has to be drained and refilled — for example, to move pipework — that adds time, and the system then needs bleeding and rebalancing.
4. New Valves
Fitting new radiator valves or TRVs is a common, worthwhile add-on. It is inexpensive but adds a little to the parts and labour.
5. Your Location
London and the South East run roughly 15–30% higher than the North of England, Wales and Scotland, reflecting higher labour costs.
6. The Condition Of The System
Old pipework, sludge in the system, or a radiator that has corroded onto its valves can all slow the job. A power flush, if the system needs one, is a separate cost.
What's Included — And What's Not
Typically included in a like-for-like radiator replacement:
- Isolating or draining as needed
- Removing and disposing of the old radiator
- Hanging the new radiator on the existing brackets and pipework
- Refilling, bleeding and testing for leaks
- Small consumables such as jointing compound and PTFE tape
Usually charged separately:
- The radiator itself, if the plumber supplies it
- New radiator valves or TRVs
- New pipework for a repositioned or upsized radiator
- Draining and rebalancing the whole system
- A power flush if the system is full of sludge
- Making good decoration behind the radiator

Can You Replace A Radiator Yourself?
A like-for-like radiator swap is one of the more approachable heating jobs for a confident DIYer: close the valves, drain the radiator, disconnect it, hang the new one on the same brackets and pipework, then reconnect, refill and bleed. The parts are inexpensive and the method is well documented.
Getting an airtight, watertight seal on the valve connections matters, and a leak here drips onto the floor for as long as it goes unnoticed. Bring in a professional for repositioning or upsizing (new pipework), when the system needs draining, rebalancing or a power flush, or when valves are seized or corroded. Any work on the boiler or gas side must be done by a Gas Safe registered engineer — replacing a radiator itself is not gas work, but it is best handled as part of properly maintained central heating.
How To Save Money On Radiator Replacement
- Keep the radiator in the same position to avoid new pipework — the biggest single saving.
- Choose a standard panel radiator unless you specifically want a designer, column or vertical style.
- Supply your own radiator once you have confirmed the size, output and pipe centres match.
- Add new TRVs at the same time so you are not paying a second call-out later.
- Bundle heating jobs — combine with other radiator swaps, or time it alongside a boiler service or thermostat replacement.
- Get 2–3 quotes and compare what each includes — valves, draining and disposal all vary.
How To Hire A Good Plumber Or Heating Engineer
Ask for recommendations, check reviews, and get a written quote that states whether the radiator and valves are supplied, and whether the system needs draining or rebalancing. Confirm the tradesperson is insured, and if any boiler or gas work is involved in the wider job, that it is carried out by a Gas Safe registered engineer.
