Removing or Moving a Radiator: Decorating, Capping Off or Relocating

Whether you want a radiator off the wall for decorating, gone for good or moved to another wall, the cost depends almost entirely on the pipework. Taking a radiator off the wall for decorating is a short job, removing it for good and capping the pipes takes longer, and moving it to a different wall costs the most because new pipe has to be run under the floor.

Three Different Jobs, Three Different Prices

People searching for radiator removal usually mean one of three jobs: taking a radiator off temporarily, removing it permanently, or moving it somewhere else in the room. Each involves more pipework than the last, and the price follows the pipework.

• Temporary removal for plastering, wallpapering or new flooring. The valves are closed, the radiator is lifted off and refitted later.
• Permanent removal where the radiator is no longer wanted. The pipes are cut back and capped, ideally below floor level, and the system is refilled and treated.
• Relocation to another wall. New flow and return pipes are run to the new position, the old tails are removed, and the floor is made good.

For comparison, a like-for-like radiator replacement on existing pipework is typically in the £100 to £300 range, as set out in our guide to radiator replacement costs. Moving a radiator involves that same draining and refitting plus new pipework, which is why it usually costs more than a straight swap.

Taking a Radiator Off to Decorate

A temporary removal is the cheapest of the three because the pipework stays as it is. The valves at both ends are closed, the radiator is drained into a tray and lifted off its brackets, and the valves stay shut until it goes back. Our step-by-step guide on how to drain a radiator shows what is involved.

The catch is old valves. Valves that have not been turned in years can seize or start weeping when disturbed, and a lockshield valve closed without counting the turns loses its balance setting. If the valves are old, it is often worth replacing them while the radiator is off, since the wall is being redecorated anyway. When the radiator is refitted, it needs bleeding, and a sealed system may need its pressure topping up.

Removing a Radiator for Good

Permanently removing a radiator means cutting the pipes back and capping them properly, not just leaving the valves shut. That usually involves draining at least part of the system, lifting a floorboard, and refilling with fresh inhibitor afterwards.

Pipes left in place with closed valves create a dead leg: a length of pipe full of still water that corrodes and collects sludge, and a valve that may one day leak behind new furniture. Cutting the pipes back to where they branch off, or at least below floor level, avoids both. On a solid concrete floor with pipes buried in the screed, capping at the wall may be the only practical option, and that should be agreed before the work starts.

Before removing a radiator, check the room will still be warm enough. A room with no heat source can become cold and damp, with condensation and mould on outside walls. If the aim is to free up wall space, a taller, narrower radiator elsewhere in the room is often a better answer than no radiator at all.

Moving a Radiator to Another Wall

Moving a radiator costs more than removing one because new flow and return pipes have to be run to the new position. On a suspended timber floor that means lifting boards along the route; on a solid floor it can mean chasing the screed or running pipe along the wall.

The main things that set the price are:

• Floor type. Timber floorboards are far quicker to work under than concrete or screed.
• Distance. Moving a radiator along the same wall is simpler than moving it across the room.
• Floor coverings. Fitted carpet, laminate or tiles have to be lifted and relaid, and tiles rarely come up cleanly.
• Pipe type. Narrow microbore pipe may need upgrading if the new radiator is larger.
• Making good. Filling and redecorating around old pipe holes is often extra.

A move is also a good moment to check the radiator suits its new wall. A radiator under a window heats the cold air falling off the glass, while one on an inside wall behaves differently. Our guide to radiator sizing and BTU explains how to check the output is right for the room.

Is It Cheaper to Move the Radiator or Buy a New One?

If the existing radiator is sound and the right size, moving it is usually the cheaper choice. If it is old, rusty at the bottom or too small for the room, fitting a new radiator in the new position costs little more in labour and gives you a better result.

The labour for draining, running pipe and refilling is the same either way. The difference is the radiator itself, so the decision comes down to whether the old one is worth keeping. A radiator that has been cold at the bottom for years is full of sludge and will carry it into its new position unless it is flushed first.

What Happens to the Rest of the System

Removing or moving a radiator changes how water flows around the whole system, so the remaining radiators may need rebalancing afterwards. Draining also lets air in, and the system should be refilled, bled and dosed with inhibitor.

A good engineer includes the refill, bleeding and inhibitor in the quote, checks the boiler pressure on a sealed system, and confirms every radiator heats properly before leaving. If any of that is missing from a quote, ask about it before comparing prices.
