Cost To Remove a Chimney – A Look at Prices

There are hundreds of thousands of homes in the UK with disused chimneys on the roof.

Many of these require ongoing maintenance to prevent roof leaks and other issues, one popular option is to reduce the height of the chimney to below the roof tiles and then cap it so it can’t be used.

Other people go further and also remove the chimney breast, perhaps to free up space in the home or as part of a major renovation.

But how much does it cost to remove a chimney and who does this type of work?

We know that outdated price guides are frustrating, that’s why we last updated our chimney removal cost guide on the .

How is a Chimney Removed?

The image below explains how a typical chimney is lowered to a point below the roof tiles:

Here is a step-by-step work schedule, it’s based on the information we received from our chosen roofing contractors:

  • Scaffold is first erected, this should meet the HSE’s guidelines for roof edge protection for workers.
  • The mortar flaunching, chimney pots and cowls are then removed and lowered to the ground.
  • The chimney stack is then dismantled brick by brick to a point below the roof tiles.
  • Roofing felt, timber and matching roofing tiles and then installed to fill the gap in the roof.
  • All waste material is sent to landfill, with any valuable items such as pots or cowls sold to a reclaim yard.
  • If the chimney stack is unusually large or tall, a small skip can be hired – see skip hire charges here

Cost to Remove a Chimney

You’ll find two price examples for the removal of a chimney stack below.

Both include the cost of scaffolding and waste removal:

Project 1

Our first example price guide is for a chimney located near the roof eaves, this is the easiest type of chimney to remove as it’s located at the side of the property and not in the centre of the roof:

LocationSmall BusinessLarger Business (5+ employees)
London Area£1250.00£1600.00
South, SW and Midlands£1200.00£1400.00
Outer Region and North£1000.00£1100.00

Project 2

Our second example is again for a medium sized chimney but this time it’s located near a gable/apex and further up the roof.

This means it will require extra scaffolding:

LocationSmall BusinessLarger Business (5+ employees)
London Area£1350.00£1750.00
South, SW and Midlands£1300.00£1600.00
Outer Region and North£1100.00£1200.00

Chimneys located on other parts of the roof will generally cost upwards of these figures.

Why Do Homeowners Remove Chimney Stacks?

Because chimneys are located in exposed locations up above the roof, they experience a significant amount of weathering, from rain and wind to snow and ice.

This often washes out the mortar joints between the bricks which in turn can lead to leaks and costly ongoing maintenance.

As the most expensive aspect of some chimney maintenance projects is erecting a scaffold, some homeowners choose to dismantle the chimney altogether if they no longer use the fireplace.

How Long Does This Work Take

The timescales below are just estimates, but they are based on answers to questions we asked our chosen roofers:

Small/medium sized chimney – will take two people between a few hours and half a day to remove a small chimney and tile over the gap in the roof.

Large chimney – it should take around a day to dismantle a larger chimney and tile over the gap.

Both of these estimates exclude the time it takes to erect/dismantle a scaffold platform.

Other Options

If you want to keep a lid on prices, there are alternatives to chimney removal:

If you want to renovate the home and this requires removing the chimney breast indoors, you can leave the external stack in place, it just needs to be supported with gallows brackets inside the loft space.

Chimney re-pointing and re-flaunching – this project involves raking out loose mortar from between the brick courses and re-pointing with a suitable sand/cement mixture (or lime if the property is old). See our price guide to chimney pointing here.

Repair or replace the lead flashing – chimneys often leak around the base of the stack, where the bricks meet the roof tiles. This area should be covered in lead to prevent leaks, this lead may split, crack or slip and is a well-known weak spot on many roofs  See this page for our leadwork price guide.

Chimney capping – instead of dismantling a disused chimney, it can be sealed off and capped. This will prevent rainwater from entering the chimney whilst allowing a small amount of airflow in which prevents condensation and mould. See this product for more information.

    This is great example of how misleading and wrong internet info can be.

    An old Chimney stack will never create leaks on its own because the mortar washes away, roofs also leak if not maintained.

    The costs will probably triple whats been mentioned here.

    A chimney breast can rarely be supported at loft level using brackets….you would need B Regs approval and calcs and most likely beams.

    The chimney stack removal may need planning permission.
