Unit must be replaced in two years - we offer a £10 discount on your replacement - so it works out to just 10p a day!

Buying a LimeStop:

We mostly sell to our own customers direct, and to trade (plumbers and heating engineers).   However, we can sell you a LimeStop direct (by post).  Please email us from the 'Contact Us' page and we’ll send you a PURCHASE EMAIL to buy.  Thank you.

Why do we use Purchase Emails?  Because we can take better care of your payment.  If you want to cancel, for example, we can do that immediately, and refund your payment the same day.  Also, there are no outside 'payment merchants' and no fear of you mistakenly paying the wrong amount, or the parcel going to the wrong address.  YOU are always in charge of your payment, and we don't see your bank or card details.

Please note that all orders are sent FREE by Royal Mail. This is often a 2-day service (working days). However, if you require your LimeStop urgently, please let us know when you order, and we can send by overnight courier. There is a £10 charge for this overnight service.
