Is there a delay for your chimney sweep?

How long to wait for a chimney sweep

Don't panic if your chimney sweep can't fit you in straight away.
But do know when it's important to stop using your fire.

As the weather turns colder, chimney sweeps get very busy and you may find yourself waiting a few weeks for an appointment.

Being due for a chimney sweep doesn't automatically mean that your chimney is blocked or dangerous. However, it doesn't guarantee that it's safe to use either.

When might it be reasonable to wait for your usual appointment?

Your chimney was swept relatively recently

If your chimney has been professionally swept within the last year and you've been using the correct fuel and everything has been working normally, you may simply be able to wait for your next routine appointment.

You only use your fire occasionally

A stove that's used a handful of times throughout the year will generally accumulate less soot than one that's burning every day. However, infrequent use doesn't rule out nests, obstructions or deterioration, particularly after a long period without use.

You have a cowl fitted and the smoke is drawing quickly up the chimney

A cowl makes it unlikely that you have accumlated a chimney full of twigs needed for birds to nest in and if the room is not smokey then you can calmly spend a few weeks in the overdue status for your sweep
If your chimney that hasn't been used for a long time but was swept after it's last use. Light some kindling and see if the chimney pulls the smoke upwards and not into the room. If it does then continue to add fuel slowly but do arrange a sweep.

Remember: These are not guarantees that a chimney is safe. If your recommended sweeping interval has passed, arrange a sweep before further use rather than assuming everything is fine.

When should you NOT use your fire?

There are circumstances when you should stop using your stove or open fire until the chimney has been professionally checked.

  • Smoke entering the room: Smoke escaping into your home, or a noticeable deterioration in the chimney's draw, can indicate a blockage or ventilation problem.

  • A suspected bird's nest or obstruction: Birds, leaves and other debris can block a chimney, even if it was swept previously. Look for twigs in the fireplace and see if you can see anything when you look up with a torch.

  • A chimney fire when you last used it: The chimney must be inspected and declared suitable for use before the fire is lit again.

  • Heavy soot or tar deposits: Significant build-up increases the risk of a chimney fire, particularly where thick, shiny or sticky tar is present.

  • A carbon monoxide alarm sounding: Stop using the appliance, get everyone into fresh air and seek urgent assistance. Never ignore a CO alarm.

  • Visible damage: Cracks, leaking smoke, smoke marks on the chimney breast above the fire, damaged flue components or other signs of deterioration need professional attention before using.

  • A newly installed or altered appliance or chimney: Don't use it until the installation has been properly checked and commissioned.

How often should my chimney be swept?

Recommended frequencies depend on what you burn and how frequently you use your fire.

As a general guide:

  • Wood: At least once a year, with more frequent sweeping if you use it everyday.

  • Smokeless fuel: At least once a year.

Always follow the appliance manufacturer's recommendations and your chimney sweep's advice. Your home insurance may also specify maintenance requirements.

A little forward planning makes all the difference

If you regularly use your stove or open fire, don't wait until the first cold weekend to arrange your sweep.

Booking during spring or summer often gives you a much wider choice of appointments and helps ensure your chimney is ready before the heating season starts. If you have left it a little last minute then look for early morning, evening and Saturday appointments. Alternatively book a ate in and in the message box explain that you are able to do sooner and we will contact you if a postponement should occur and a booking becomes available.
Best thing to do is book when you are paying your invoice online. You can book a year ahead and then move the appointment to better suit you closer to the date.

Our advice: If your chimney is due for sweeping, get an appointment booked. If you have any concerns about its condition or performance, stop using the fire and seek professional advice rather than taking a chance. A few weeks without a fire is inconvenient. A chimney fire or carbon monoxide incident could be far worse.
