For lost international orders we will endeavour to claim compensation directly from The Royal Mail, they not deem an item to be lost until 25 days have passed. Replacement items will only be sent once we have received compensation from The Royal Mail which may take as long as two months. Refunds are not available for lost orders outside the UK. Please note lost orders are rare, only two international orders have been lost in the post in the last three years.  

Some of our larger items are not held in stock (electric window kits, designer central locking kits etc) and are sent out directly from a holding warehouse. Items sent from our warehouse are sent via couriers which unfortunately charge different rates for some parts of the UK. Delivery charge to the Scottish Isles, Northern Ireland, Isle of Man, Isles of Scilly and Channel Islands will be charged a flat rate of £25, if in doubt please contact the office.

We want you to be delighted with the products you purchase from us. If you receive goods that are unwanted, you the consumer has a 7 working day cancellation period. This 7 day period starts the DAY ON receipt of the goods.

Please note that there is a 20% or £5 handling charge which ever is the greater plus the cost of postage. The exception to the above statement are remote controls and touchkeys which cannot be returned, if in doubt please call our sales number before ordering. Please return the original receipt (not a photo copy), without this we will not be able to process a refund. If the returned goods have been used or part fitted or damaged, missing components/packaging or incomplete in any way we reserve the right to refuse a refund. The exception to the above is for orders outside the UK for remote fobs. Meta fobs supplied by Abacus are designed to work with UK/Ireland supplied Meta Alarm systems and as such may not work with equivalent devices supplied to other parts of the World, as such we offer no guarantee that they will work with these products. This remote fob will not work with Meta devices supplied to either Belgium or Holland as these countries use a different frequency for controlling the alarm system. We offer no refund should the remote fobs not function correctly with non UK/Ireland supplied alarm systems - you buy at your own risk. You the customer are responsible for the costs of any returned items. 

Only the person who bought the item can make a warranty claim & must supply the original or a copy of the original receipt with the faulty item(s). Abacus car alarms are not responsible for the postage costs to us but will cover the return postage cost of the item(s).

Please make sure you understand the product and the vehicle instructions before fitting or get the help from somebody who does.
On certain goods which are sealed in polythene packaging (the factory replacement electric window kits) it is imperative that what you have ordered is exactly the same as the mechanisms in your vehicle. This can be done by taking out the original window mechanisms from your vehicle and comparing them through the packaging of the replacements. Once the packaging has been broken on the electric window kits there will be a 50% handling charge removed from your account if you send the items back. If the window kits are faulty we will replace or repair them as soon as possible.   

Also the Thatcham products supplied by Autowatch are all sealed in plastic bags, once these bags have been opened there will be a 50% handling charge added should you return these goods.
