Chimney breast removal cost

If you’re planning a renovation, you may be considering removing a chimney breast to free up space in a room, rework a layout, or simplify a loft conversion. Chimney breast removal can be a great upgrade, but the cost varies widely because it often involves structural support, waste removal, and making good walls and ceilings afterwards.

What affects chimney breast removal cost?

1) Structural support (major factor)

Chimney breasts often support chimney masonry above. If you remove a breast on a lower floor but keep a stack or breast above, the contractor may need to install:

  • a steel beam (RSJ) or similar support
  • appropriate brackets/supports (where suitable)

The correct solution depends on your property and what you’re removing. This is why costs vary.

2) How many floors are involved

Removing a breast on one floor only is usually cheaper than removing it on multiple floors. However, removing only the lower breast can require more support for the masonry above.

3) Whether the chimney is shared (terrace/semi)

If you share a chimney with a neighbour (common in terraced and semi-detached homes), the job may involve extra considerations and coordination. That can affect cost and timelines.

4) Access and waste removal

Chimney masonry is heavy. Costs rise if the contractor has to move rubble through tight hallways, narrow side access, or multiple flights of stairs. Consider skip hire for waste removal.

5) Making good and finish level

The “finish” makes a big difference. Quotes may include:

  • basic patch plastering
  • full wall replastering
  • new skirting boards and trim
  • ceiling repairs
  • redecorating and flooring repairs (sometimes excluded)

Always check what’s included.

6) Services and flues

If the chimney breast contains services (wiring, vents) or connects to an appliance, you may need additional work to reroute or decommission safely.

What should a chimney breast removal quote include?

A good quote should state:

  • exactly which chimney breast(s) will be removed (which rooms/floors)
  • what structural support is included (beam/brackets, supply and installation)
  • how the area will be made good (plastering scope, ceiling repairs)
  • whether waste removal/skip is included
  • dust protection measures and how they’ll protect floors
  • timescale and start date estimate
  • VAT included or excluded
  • warranty/guarantee (where applicable)
  • proof of public liability insurance

If the quote is vague, ask for a written breakdown before agreeing.


Do you need Building Regulations?

Chimney breast removal can be structural. In many cases, you’ll need to consider Building Regulations compliance. Your contractor should be able to advise on what applies to your situation.

If your property is listed or in a conservation area, additional considerations may apply.


How long does chimney breast removal take?

Timescales vary, but commonly:

  • demolition and removal: a few days
  • structural support: during the main phase
  • plastering and making good: additional time
  • drying time before decorating: depends on plastering

A multi-floor project usually takes longer than a single-room removal.

Chimney breast removal cost FAQs

How much does chimney breast removal cost in the UK?

Costs vary widely. Removing a chimney breast in one room often falls in the low thousands, while removing breasts on multiple floors can cost more due to structural support and making good.

Is it cheaper to remove the chimney breast on one floor only?

It can be, but removing a lower breast while leaving masonry above often requires structural support, which can increase cost. Your quote should explain what support is included.

Does the quote include plastering and making good?

Sometimes. Always check what level of plastering, ceiling repairs and finishing is included, because it can change the total cost significantly.

Do I need Building Regulations approval?

Chimney breast removal can be structural, so Building Regulations considerations often apply. Confirm requirements for your property before starting work.

Is chimney breast removal messy?

It can be. The job involves rubble and dust. A good contractor will protect flooring, control dust as much as possible, and remove waste responsibly.
