Sentinel X700 Biocide provides protection for underfloor central heating systems against bacterial and fungal contamination. Such contamination can cause blockages in the system, unpleasant smells, and corrosion within the system, disrupting the smooth and efficient operation of the underfloor heating system.

Our main depot is in Kingsfold, near Horsham on the Surrey and Sussex border. The postcode is RH12 3SD. We operate a local delivery service from this single depot. Our catchment range for local deliveries is an average of 25 miles.
If a product has a ‘Local Delivery’ tick we are able to deliver this with our own lorries most of the time. Sometimes we will use external hauliers.
Deliveries will be made to kerbside only to the nearest safest point to the delivery address and off loaded onto firm ground. If the driver is requested to leave the highway and enter the property or site, any damage which may be caused to yours or the local authority's property (such as footpaths and manhole covers), will be your or your agents' responsibility, together with the cost of any repairs or replacement items. Entering properties or crane off loading over walls, hedges and fences will be made at our drivers discretion unless previously arranged with the transport office.
We will endeavour to deliver on the day specified, but cannot be held responsible should delays occur due to circumstances beyond our control. Please try and avoid arranging for tradesmen to begin work before the materials have arrived as D W Nye Ltd will not be held liable for any costs incurred as a result of not meeting a delivery date.
Many of our products can be sent anywhere in the country, either by post or by a haulier. This means the product will either come from ourselves or it will come from a 3rd party stockist. With most haulier deliveries this will be either in a van or in a box lorry with a pump truck. They will not be able to deliver with a crane offload lorry. If you have any special delivery requirements please let us know.
Collection from Store:
These items are expected to be in stock most of the time (sometimes lead times do get extended and we are unable to have a 100% stock holding 100% of the time). You will need your order number and the card you used to pay online.
We have a range of machinery on site to load your materials onto your vehicle whether it be loose or bulk bagged aggregates, part or full pallets of bricks or blocks and if you are in a hurry please ring in advance and we can prepare your order to save you time when collecting.
Some items in construction and landscaping are not always easy to handle and need either assistance or a crane to load/unload the materials. We have tried to make sure this is clear when ordering.
