Removing a split means recovering the refrigerant, disconnecting pipework and electrics, taking the indoor and outdoor units away, and making good the holes. Venting the gas to atmosphere is not a shortcut. It is an offence, and it is not a job for a general builder with a hacksaw. A 2026 illustration for a straightforward domestic removal, with recovery and basic making good, often sits in the high hundreds, and rises into the low thousands if access needs scaffold, the gas charge is awkward, or the wall needs proper reinstatement. Use an F-gas certified company for the recovery. Price the holes as well as the scrap metal.
Recover the gas before anyone cuts the pipes
The system holds fluorinated refrigerant. A certified person recovers it into a cylinder before the pipes are opened for good. That step has a time and a paperwork shape. Skipping it to save a callout is the expensive kind of saving. Recovery under the GOV.UK F-gas rules is mandatory. Do not vent the system. You cannot cut the pipes and bin the unit yourself. Electrics and making good still need competent people. Isolate the electrical supply safely. That may be a different competent person.
After recovery, the indoor unit, outdoor unit, brackets and redundant copper can go. Some of that is scrap and some is waste electrical equipment. A proper price says who takes it and where. Leaving a condenser on the path for you to deal with is an incomplete price. Ask for waste removal in writing. If you are removing because a new system is going in the same place, ask for recovery and the new install on one visit. Paying two access costs is how a cheap removal doubles. If the old system is R410A, recovery still happens. The new small split you are offered will almost certainly be R32. That is a new matched pair, not a reason to open the old pipes and walk away. Removal is included in a replacement only if the price says so, including whether the old brackets are reused or replaced.
Holes, scaffold and a dead condenser on a balcony
A ground-floor single split with a short pipe run and a van that can park is the lower illustration: often high hundreds once recovery, labour and disposal are honest. First-floor plant, a flat with a managing agent, a roof frame, or a system that has leaked and needs longer recovery work moves toward the low thousands or beyond. As a 2026 illustration, a simple domestic strip-out with recovery is often in the high hundreds. Scaffold, roofs and reinstatement move it into the low thousands.
Core holes, trunking screws and stained condensate streaks are what you live with after a careless strip-out. Making good holes, trunking scars and bracket marks is part of the job. External holes need a weatherproof fill. Internal holes need a finish you have agreed: plaster, a cover plate, or decoration left to you. Write that down. On flats and listed buildings, removal can need the same consent conversation as installation, because you are altering the outside. A dead condenser left on a balcony still hums as a management problem even when it is switched off. Planning Portal heat pump notes are about siting plant. Your lease is about whether you may touch the fabric at all.
