Treework
Do you charge to look at our trees?
No, we offer a free, no obligation site visit to inspect the trees and discuss your specific requirements. This allows us to provide you with an accurate quote for the works discussed.
Can you give me an estimate over the phone/email?
Unfortunately not, as every tree is different and each job needs individually assessing in order to provide an accurate and competitive quote. We do offer free, no obligation site visit and quote to your specific requirements.
Will you get rid of the waste?
Yes, we will remove all arisings from the job (if required) which will be upcycled as much as possible in line with our ethical and sustainability policies.
Do you cut hedges?
Yes, we can prune, reduce or remove any kind of hedge, although many hedges cannot be worked on during bird nesting season (April – August/September).
Are you insured?
Yes, we hold £5million public liability insurance.
Yes, all our members of staff hold the appropriate NPTC/Lantra approved tree work qualifications for the roles they occupy, as well as HSE approved treework specific emergency first aid training.
Are you properly qualified?
Do we need to get permission from the council to cut our trees down?
Only if your trees are covered by a Tree Preservation Order or your property lies within a conservation area. In either case we will, as part of our service, liaise with the council to submit the relevant applications and gain consent to the works on your behalf.
Biomass
How much woodfuel do I need?
The volume of fuel required for storage will depend on the daily heating energy required by the biomass boiler, the number of days storage required and the calorific value of woodfuel used. Storage volume should be at least twice the delivery volume. Consideration should be given to the size of delivery vehicles that can access the site and any limitations imposed on the frequency of deliveries.
How much does woodchip cost?
Typically woodchip costs in the region of 2.5 to 3 pence per kWh. However, there are a number of factors that affect price including method of delivery and fuel store design, which can amount to one third of the cost of the fuel. It is crucial this aspect is given careful consideration during the installation process as poor design will result in a potentially expensive delivery/storage solution for the life of the boiler i.e. 25 years. A long term fuel supply contract will ensure continuity of supply, reliability and price stability.
When do I need to think about ordering woodchip?
For many dry fuel boilers (less than 35% moisture content) consumers need to be thinking about their fuel up to six months in advance longer if it is a large boiler (>1MW). Timber needs at least one drying season to reach less than 35% moisture content. The larger the fuel demand the more notice required to source suitable fuel. Don’t leave it too late! A long term fuel supply contract will ensure continuity, security of supply and price stability.
How should woodchip be stored?
Woodchip is delivered to site in bulk transport. The unloading process is usually by gravity from a tipper or chain bedded truck. The fuel store is therefore usually at ground level or below ground. Good fuel store design and planning how the delivery will be received are very important; one third of the fuel cost can be from a poorly designed fuel store and delivery method.
Why is moisture content critical?
Many boilers are designed to burn woodchip or logs with a maximum moisture content of 35%. The ideal moisture content is 20-25% – any less than this and the woodfuel will burn too fast. Although this can be achieved by air-drying wood, freshly cut ‘green’ timber and tree surgery wastes will be of much higher moisture content – typically 50-60% – which will cause many boilers to shut down. The simplest method of ensuring good quality, consistent supply is to find a reliable supplier.
Is woodchip size important?
The size and shape of woodchips is important to ensure the smooth running of the boiler. It is important that specialist woodfuel chippers are used, as general purpose wood chippers can produce long slivers which can lead to blockages in fuel-feed systems.
Is woodfuel clean?
Woodfuel presents no risk if accidentally released into the environment and there are no harmful by-products. The flue gas is smoke free and the ash content of between 0.5% and 1.5% by volume is minimal.
Why is wood a carbon neutral fuel?
As it burns, wood produces carbon dioxide – one of the main greenhouse gases responsible for climate change. But this CO2 is absorbed by new growth. This means that no extra carbon is put into the atmosphere – which is why wood fuel is carbon neutral. Although, during processing more CO2 is released to the atmosphere, this is insignificant in comparison to other fuel types the ’embedded’ energy in woodchip is negligible, much less than wood pellets.
Woodland in the UK is a renewable resource and therefore as trees are felled new trees are planted or re-grow as coppice. During the process of photosynthesis carbon is stored in the growing tree and the woodland soil. In the UK woodlands are managed in line with the UK Forest Standards and all felling is controlled by the Forestry Commission. The standards ensure that woodland is managed sustainably and to the best environmental standards.
Does using woodfuel for boilers damage woodland?
On the contrary, a demand for logs and woodchip creates a market for timber and wood residues that would otherwise go to landfill. It can help provide financial support to woodland management and can have a positive impact on flora and fauna, if managed correctly. Every woodland has a sustainable yield, which can be harvested indefinitely without depleting supplies.
Can woodfuel benefit the local economy?
A growing wood energy industry benefits the local economy because it generates income for owners, contractors, processors and suppliers. The increased forest management improves future productivity and asset value. Wood energy crops also have the potential to offer an important diversification opportunity for farmers.
