There are approximately 60,000 thatched properties in the UK, of which 50-80 suffer a serious fire each year, most of which are completely destroyed. 90% of the homes struck by thatch fire have a combination of a wood burning stove either a flexible chimney liner or no liner at all.
Chimneys should be checked to ensure the brick or stonework is in good condition. Old or poorly maintained chimneys with loose or missing bricks & mortar and not lined, could allow hot gases and smoke to escape into upper rooms, the loft space or directly onto the thatch. If re-thatching works are taking place and the thatch around the chimney stack is removed, the thatcher will be able to advise on its condition.
Ensure chimneys are regularly swept by an experienced and qualified chimney sweep. This normally needs to be done at least twice a year, however if the chimney is used frequently during the winter period then additional sweeping may be required. Your sweep will be able to offer you further advice. Many chimney engineers and other specialist companies offer a CCTV survey, this is recommended to check the internal condition of the flue. Again check with your property insurer because some of them have a list of approved companies.
A number of thatch fires occur as a result of old or inappropriate flue liners, therefore chimneys serving either an open fire or multi-fuel appliance should be suitably lined. Contact an appropriate professional body such as HETAS so a registered chimney engineer can review the liner (if already installed) to ensure it is fit for purpose for the type of appliance or fire in use.
An engineer will also be able to advise on the condition of the liner and recommend on how often it should be checked. If you are considering installing a wood-burner or similar, again contact HETAS who will advise on the most suitable appliance and liner for the property.
Good advice for your thatched property.
During recent times we have seen an increase in the number of calls from people who are in the process of purchasing a thatched property and are looking for more detailed advice; covering areas such as chimneys, electrical systems, insurance providers, and much more to include the names of local thatchers.
In light of the increased requirement in the industry for more advice, we have updated our safety advice leaflet. The new leaflet gives guidance on areas such as chimneys, wood burning stoves, electrical systems, detectors & alarms and fire barriers.
Over the coming weeks we will be supplying thatcher’s with copies of the leaflets so that if required, they can hand out these to home owners.
Our system was chosen to be included in the Listed Heritage Shopping section of The Listed Property Owners Club Magazine.
Listed Heritage Magazine is a high quality magazine which is distributed to 19,000 listed property club members.
The Thatch Alert Chimney Monitor System has been specifically designed to monitor the temperature of the chimney brickwork at the point where it meets the thatch. The system acts as an early warning device to inform the home owner of potential high temperatures.

Fires & Fireplaces November 2013 Issue
Chimneys in thatched properties.
Thatching Advisory Services collaborated with Hetas on an Editorial in The Technical column of Fires & fireplaces November 2013 Issue; to offer guidance on how to ensure chimneys installed in thatch comply with building regulations.
Rob Norcott, Director of Thatching Advisory Services, recently gave a joint presentation with HETAS to Cheshire Fire and Rescue Service about the importance of fire safety for thatch roofs.
The presentation, attended by representatives from Cheshire Fire and Rescue Service and the North West regional office of the NFU Mutual, focussed on the common causes of thatch roof fires and the preventative measures and products available.
The attendees were made aware of the issues and contributing factors for thatch fires and the solutions, products and preventative measures available to help reduce the risk in the event of a fire.
The presentation included the use of comprehensive Thatch Fire Protection Systems which are a mix of either TAS100 Thatch Fireboards or Thatch Firewall with our non-combustible Thatchbatt® product.
Rob was also able to explain how the fire retardant spray ‘Thatchsayf’ works by foaming (intumesce) and forming a carbonised char, which binds the thatch stems together, cutting off the supply of oxygen to the fire, delaying the spread of flame and lowering the radiated heat output.
HETAS are the official body recognised by Government to approve biomass and solid fuel domestic heating appliances, fuels and services.
Rob Norcott of Thatching Advisory Services was invited to write an article for the International Fire Fighter magazine.
The IFF magazine reports world wide to professionals in municipal and industrial fire and rescue services. The magazine is subscribed to across the globe in 36 countries.
The 5 page piece was centered around the importance of separation in construction on thatched roofs. The article also takes you through common causes of thatch fires and the various systems and preventive measures available.

Dramatic and devestating blaze consumes thatched roof in minutes……
Pictures from the Oxford Mail show the devastation fire can wreak on properties with thatched roofs. Seven fire crews tackled the blaze in East Hagbourne overnight on Saturday.
“The main causes of fires are chimneys being too short, which allow embers to escape on to roofs, and heat transfer from chimneys,” said Rob Norcott, director of Thatching Advisory Services. “Prevention is the best cure.”
Firefighter Paul Webster, who was the incident commander at Hagbourne this weekend, said: “The speed at which the fire spread throughout the whole roof shows how little time people will have to think in a fire situation.
Five thatches have been destroyed by fire in Oxfordshire so far this year – in Hagbourne, Besselsleigh, two neighbouring houses at Barford St Michael in June and a home in Swalcliffe in March – compared to one in all of 2012.
Thatching Advisory Services has added an informative new page to its website.
HETAS are the official body recognised by Government to approve biomass and solid fuel domestic heating appliances, fuels and services including the registration of competent installers and servicing businesses.
Although HETAS have a comprehensive website, we have listed a number of areas that thatched property owners are most likely to be interested in. http://www.thatchingadvisoryservices.co.uk/Hetas.asp
