Direct answer
If a radiator is still connected to your central heating system, it needs to be drained and disconnected from the pipework first - it isn't something a general clearance carrier can simply unbolt and carry out, because there's water inside it and in the pipes it's joined to. This is normally done by the homeowner (if confident doing so) or a plumber/heating engineer, not by the clearance team. Once a radiator has been properly drained, disconnected and is lying free of the pipework, it can be collected like any other piece of bulky household waste. Steel and cast-iron radiators sometimes have scrap metal value too, which is worth asking a carrier about directly rather than assuming a figure, since it varies by carrier and by current scrap prices.

Why radiators need draining and disconnecting first
A radiator isn't a free-standing object - it's plumbed into the central heating system.
A central heating radiator is connected to your home's heating system by pipework, usually with a valve at each end, and while it's connected it's full of water (and, in many systems, a small amount of corrosion inhibitor added to the heating circuit). That water doesn't disappear just because the radiator is being taken off the wall - the pipework on either side of it is also part of a pressurised, closed loop that runs through the rest of the property. Disconnecting a radiator without draining it properly first can mean water coming out of the pipe ends, which can cause a mess or, in the wrong spot, actual water damage to flooring or a ceiling below.
This is a genuinely practical reason for the sequence, not a legal-safety requirement in the way that, say, gas appliance work is - draining and disconnecting a radiator is a plumbing task, not a gas-safety one, and there's no equivalent of a Gas Safe registration needed to do it. Even so, it's still a job that benefits from being done properly: isolating the system, draining the radiator (and often part of the circuit near it) through a drain-off valve or by using a radiator bleed valve and a container, then disconnecting it from the pipework cleanly so the open pipe ends can be capped or blanked off if the radiator isn't being immediately replaced.
A general house clearance or junk removal carrier is set up to load, carry and dispose of bulky items - they are not plumbers, and collecting a radiator that's still full of water and attached to live pipework isn't something they're equipped or insured to do safely. In practice, this means the draining and disconnection has to happen before the radiator is ready for a clearance booking, either carried out by the homeowner if they're confident doing so, or more commonly by a plumber or heating engineer, particularly if the radiator is being removed as part of a wider boiler upgrade or heating system replacement where a professional is already on site.
If you're not sure whether a radiator counts as "fully drained", a reasonable check is whether it can be tilted and moved without any water running out of the valve connections, and whether the open pipe ends at the wall have been capped, blanked or otherwise made safe rather than left open. A radiator that's merely been turned off at the valves but not actually drained can still hold a significant amount of water inside it, so "isolated" and "drained" aren't quite the same thing - it's worth confirming with whoever carried out the work that draining specifically was completed, not just that the heating was switched off.
It's also worth bearing in mind that a radiator forms part of a shared, pressurised heating loop with the rest of the property, so draining one radiator in isolation sometimes means briefly affecting part of that wider circuit, depending on how the pipework is arranged. This is one of the reasons it tends to sit more naturally with a plumber or heating engineer's normal scope of work than with a general clearance booking - they're already familiar with isolating and draining sections of a heating system safely, whereas a clearance carrier's expertise is in moving and disposing of items that are already free of the property's services.
Steel panel radiators vs cast-iron radiators
Weight and material affect both how they're handled and what happens to them afterwards.
Most radiators fitted in London homes since the latter half of the 20th century are steel panel radiators - flat, pressed-steel panels, often with convector fins on the back, that are relatively light for their size and straightforward for one or two people to carry once they're off the wall. Older properties, particularly period conversions and houses that haven't had their heating fully modernised, sometimes still have original cast-iron radiators - the traditional column or "hospital-style" radiators with individual sections bolted together.
Cast-iron radiators are dramatically heavier than steel panel radiators of a similar size - a full-length cast-iron radiator can weigh well over 50-80 kg depending on its length and number of sections, compared with a steel panel radiator of similar dimensions that might weigh a fraction of that. This weight difference affects how many people are needed to carry it safely, how it's loaded, and sometimes whether stairs or a narrow hallway make it a two-person job rather than one.
It's also worth knowing that cast-iron radiators in good condition are sometimes reclaimed and resold rather than scrapped, particularly by architectural salvage yards or buyers renovating period properties who want an authentic period-style radiator rather than a modern reproduction. If a cast-iron radiator looks to be in reasonable condition - not badly rusted, cracked or missing sections - it may be worth checking whether a reclamation yard or salvage dealer is interested before assuming it's only fit for scrap. Not every cast-iron radiator will be wanted this way, and condition and style both matter, but it's a question worth asking rather than skipping.
There are also radiator types that sit somewhere between the two extremes. Aluminium radiators, used in some newer or more design-led installations, are typically lighter again than steel panel radiators for a comparable output, while designer or towel-rail style radiators in bathrooms can vary considerably in weight and material depending on their finish. Knowing roughly which category a radiator falls into - panel steel, cast-iron, aluminium, or a bathroom towel rail - helps a carrier judge how many people and how much space the job needs, and whether any particular handling care is needed for a decorative finish such as chrome plating.
The number of sections on a cast-iron radiator also affects both its weight and, to some extent, its resale interest - a short two or three-section radiator under a window is a very different proposition from a long run spanning most of a wall, both in terms of what it takes to carry and in terms of what a salvage buyer might offer for it. If several cast-iron radiators are coming out of the same property, it can be worth photographing each one and roughly measuring its length before contacting a reclamation yard, so they can give a more informed response than a general enquiry would get.
What it typically costs to have removed (once drained)
There's no separate "radiator" price line - it's priced as general bulky and metal waste.
houseclearance.co doesn't publish an itemised price specifically for radiators, because carriers don't generally quote that way - once a radiator has been drained and disconnected, it's collected and priced the same as other bulky metal household waste, based on the volume and weight it takes up rather than what the item is. The general indicative price by van load bands on our pricing page give a reasonable sense of where a radiator collection is likely to sit.
A single drained radiator, collected on its own, will often fit comfortably within the "Single item minimum charge" band (indicatively around £65 – £95), since it's a one-off bulky item well under the weight and volume thresholds for that tier. If several radiators are coming out together - for example during a boiler or full heating system upgrade - the job scales up with the number and size of radiators involved, and could move toward the "1/4 van load" band (indicatively around £145 – £195) or the "3/8 van load" band (indicatively around £210 – £265) depending on exactly how many are being collected and how heavy they are, particularly if any are cast-iron.
These figures are indicative only - the actual price is set by the independent carrier who quotes your specific job, not a fixed, company-wide rate. Some carriers that deal in scrap metal may also offer a partial credit for the steel or cast-iron value of old radiators, which could reduce the price you're quoted, but this isn't guaranteed or offered site-wide, and genuinely depends on the individual carrier and current scrap metal prices at the time. There's no single published scrap-value figure to quote here - it's worth asking directly when you request quotes rather than assuming a particular discount. See our scrap metal clearance service page for more on how that side of things tends to work.
When requesting a quote, it helps to describe the job as specifically as possible rather than just "radiator removal" - mention the number of radiators, roughly how large each one is, whether any are cast-iron, and whether they're already drained and sitting ready for collection or whether some are still fixed in place. A carrier working from a vague description has to price with more margin for the unknown, whereas a clearly scoped job, even a rough one, tends to get a more accurate first quote and fewer surprises once they arrive.
It's also worth remembering that the van load bands referenced above cover general bulky waste collection across the whole site, not a radiator-specific pricing table, so they're a useful point of reference rather than a guarantee. Where a job includes radiators alongside other items being cleared at the same time - old carpets, furniture being replaced, or general building waste from the same renovation - the radiators are usually just folded into the overall volume and weight of that job rather than priced separately at all.
Multiple radiators from a heating system upgrade
Batching old radiators into one collection is usually more efficient than one at a time.
If you're replacing a whole heating system - swapping out an old boiler along with most or all of the radiators it serves - it's generally far more efficient to have the old radiators drained, disconnected and set aside by your heating engineer as the installation progresses, then collected together in a single clearance booking once the job is finished, rather than arranging separate collections each time a radiator comes off the wall.
A single collection for, say, six or eight old radiators from a whole-house upgrade means one access visit, one loading trip and one quote to compare, rather than repeating that process several times over the course of the installation. It also gives the carrier a clearer, more accurate picture of the total weight and volume involved when you request your quote, which tends to produce a more reliable price than guessing based on a single radiator and multiplying it.
It's worth keeping track of where old radiators are stored between being taken down and being collected, particularly on a multi-week installation where several rooms are being worked on at different times. A corner of the garden, a garage or a covered area near the collection access point works well, so the carrier isn't searching the property for radiators left in different rooms on the day. If any radiators are still damp from draining, giving them a little time to dry out before storage helps avoid rust marks forming on flooring or other items stacked nearby.
If your heating engineer is sourcing new radiators to match the old installation points, it's also worth asking them whether they're able to recommend a disposal route for the old units as part of the overall job, since some heating contractors have existing relationships with scrap merchants or clearance firms from previous installations. Even where they don't arrange collection themselves, their view on condition - particularly for any cast-iron radiators - can be a useful second opinion before you decide whether to explore reclamation or simply book a standard clearance collection.
Access and practical considerations
Radiators are awkward rather than heavy (unless cast-iron) - length and edges matter.
Even once drained, radiators can be awkward to move through a property - they're long and relatively rigid, can have sharp or rough edges along the convector fins on the back of a steel panel radiator, and don't bend or fold to get round tight stair turns the way some furniture can be tilted or angled. Wrapping or padding a radiator before it's carried helps protect walls, doorframes and stair banisters from scrapes, particularly on a narrow staircase or through a period property with original woodwork.
It's also worth checking whether any thermostatic radiator valves (TRVs), brackets or wall-mounting brackets are still attached to a radiator that's being collected. These small fittings are easy to overlook but can catch on clothing, bags or other items during loading, and flagging to the carrier that fittings are still in place (rather than removed separately) helps them handle the item appropriately and avoid damage to the valve or bracket if you want to keep it.
Flooring along the carrying route is worth a moment's thought too - a drained radiator can still carry residual damp or a light film of corrosion inhibitor on its lower edge even after proper draining, and resting it directly on a carpet or polished floor during loading can leave a mark. Laying down an old towel, dust sheet or offcut of cardboard along the route from the room to the vehicle is a small step that avoids this, and it's a reasonable thing to have ready yourself even if the carrier brings their own protective sheeting as standard.
Lift access matters more than it might first seem for radiator collections in London flats, since a long, rigid item is harder to manoeuvre into a standard passenger lift than a piece of furniture that can be tilted on its side. If a property only has stair access, or a lift too small for a full-length radiator, it's worth mentioning this when requesting a quote so the carrier can judge whether extra time or an additional person will be needed, rather than this being discovered for the first time on the day of collection.
What to confirm before booking
A short checklist that makes a real difference to how accurate your quote is.
- That each radiator has been fully drained and disconnected from the pipework before the collection date
- Whether each radiator is a steel panel type or a heavier cast-iron type
- How many radiators are being collected in total
- Access details: stairs, narrow hallways, lift availability and distance to where a vehicle can load
- Whether any radiators are still fixed to the wall and not yet taken down, rather than already removed and waiting
- Whether you want to explore scrap value or reclamation separately before the radiators are collected as waste
None of this needs to be exact - a rough count and a note on whether the radiators are steel or cast-iron is usually enough for a carrier to give a realistic quote, and it reduces the chance of the price needing to change once they see the job in person.
Frequently asked questions
The questions that come up most often before arranging radiator removal.
Do radiators need draining before removal?
Yes - a radiator that's still connected to the central heating system holds water and is plumbed into the pipework, so it needs to be drained and disconnected from the pipework first, usually by the homeowner or a plumber/heating engineer, before a clearance carrier can collect it.
Is draining a radiator the same legal requirement as disconnecting a gas boiler?
No - draining and disconnecting a radiator is a plumbing task, not a legally restricted gas-safety task like disconnecting a gas boiler, which has to be done by a Gas Safe registered engineer. A radiator itself doesn't require a Gas Safe engineer, though it should still be drained and disconnected carefully to avoid water damage.
Do old radiators have scrap value?
Steel and cast-iron radiators can sometimes have scrap metal value, and some carriers may offer a partial credit. This varies by carrier and current scrap prices, so it's worth asking directly rather than assuming a figure.
How many radiators are typically removed in one job?
Anywhere from a single replacement radiator to a whole-house set during a heating system upgrade. Mention the approximate number when requesting a quote so the job is scoped accurately.
Are reclaimed cast-iron radiators sought after?
Yes - original cast-iron radiators in good condition are sometimes sought after by reclamation yards or buyers for period properties. It's worth checking before assuming an old cast-iron radiator is only fit for scrap.
What if water leaks during removal?
Draining it properly beforehand should prevent this, but it's sensible to have towels or a container ready just in case, and to flag to the carrier if a radiator wasn't fully drained before they arrive.
Got old radiators ready for collection?
Make sure they're drained and disconnected, then compare quotes from licensed local carriers.
