Customers with older woodburners or multi-fuel stoves

If you have an old wood burner that was installed before 2010 then it is likely that it doesn't meet current building regulations and safety standards. Your appliance should have a physical connection directly from it to the top of the chimney. This is to make sure that gases and soot are fully burnt and don't gather in the chimney causing flammable areas that can  set on fire. Stoves installed after 2010 tend to have a flexible liner fitted, or are connected to clay liner blocks and are safer to use as well as burning fuel more efficiently; saving you money as improving air quality. When stoves are fitted, the installer must make sure that there is access for future sweeping to remove the soot and debris in the chimney or flue. Stoves without a liner must therefore have a sweeping hatch, usually in the register plate. 

HETAS Warning - Unsafe to Use

Please note that your log burner may not meet building regulations if....
- it does not have a flexible liner connecting the exit pipe to the chimney
- it does not have a removable baffle plate inside the stove
- it does not have a sweeping hatch in the closure/ register plate above the burner
- it needs to be physically removed in order to access the chimney and/ or closure plate
- you do not have a HETAS certificate of installation for it


In these situations we will not be able to sweep it fully and will have to declare it unsafe to use.
You will be charged £40 for the visit and will receive a certificate outlining the issues encountered.
A quote for remedial works will be provided and the £40 refunded should you choose to go ahead with the quote.

Check the time

We need to come inside to sweep your chimney. Make sure that someone will be in during the 4 hours time slot booked.

If your appliance runs your central heating system, you should book a breakfast appointment which guarantees us to arrive before 9am.

This will enable you to get the fire back on as quickly as possible.

Check the pot

It may be dark or raining when we visit so take a look at your chimney pot before we arrive and check to see if you have a cap or cowling fitted.

If you suspect yours is loose / of a push-fit design please speak with our engineer upon arrival, as this may cause us problems.

Check after we finish that it is still there, just in case it has been dislodged by the brush.

Protect Valuables

We are very careful but accidents can happen so remove any valuables or precious knick-knacks from the fireplace area.

We bring a dustsheet for the floor so should not leave behind any dust or soot but advise covering new, expensive, white, or cream coloured furniture and carpet, just to be safe.

We don't always have time for a cup of tea, so don't feel that you have to offer. Biscuits however are always welcome!

What if we can't sweep the chimney?

Standard Chimney Sweep 

Chimney flue no more than 10m tall and 45cm wide. In working order and not blocked internally ( e.g. birds nest ) or access to chimney blocked off ( e.g. boarded over/ gas fire fitted ). 

Chimney Too Tall

If your chimney is taller or wider than average, we charge a little more because it takes longer to service than a regular sized fireplace and flue. 

Birds Nest Removal

Removal of a bird’s nest may increase the cost of the service depending on how long it takes to remove. At certain times of the year we are unable to remove a birds nest due to the Wildlife & Countryside Act 1981.
If you think you may have birds nesting or are seeing a lot of twigs dropping into your fireplace please let us know before our visit, as we may need to postpone until the birds have left the nest. We recommend fitting a bird guard to prevent birds nesting in your chimney or flue.

If we find that there are birds in your chimney that have not yet fledged, you will be charged for an inspection and certifcate sent advising you not to use the fire until the birds have left the chimney. This is usually around August time.
