Historically, multipoint locks were generally used on uPVC doors due to the amount of flex and twist plastic doors were vulnerable to to. Over the years they have been introduced to wooden and metal doors for added security offered by having multiple locking points up the length of the door.
Now, with the influx of composite doors on the market which are mostly all using multipoint locks, all these multipoint locking systems are becoming more and more popular, and are slowly becoming the 'norm' for most doors being produced by door manufacturers now. This means that as time moves on, when locks need to be replaced, you'll be looking at replacing either the full multipoint locking strip, or in some cases you may be able to simply replace the central locking gearbox mechanism.
With multipoint locking solutions becoming more and more popular, the question has been raised for years about whether or not you can get a BS3621 multipoint lock. The answer has always been no, and while it technically still is the case, Yale have pioneered the PAS3621 standard, which is effectively equivalent to BS3621 but specified for multipoint locking systems. You can read all about PAS3621 here.
We list all the most popular multipoint locking brands below. These are usually quite easily identified by manufacturer markings on the metal locking strip on the door. Once you've identified the manufacturer, you can usually determine which lock you require by the type and quantity of locking points. For example, if you have a lock stamped 'GU' and you can see two hooks, two little roller-cams, and then the central latch and deadbolt, you'd want to look in the GU multipoint locks section, for a 2hook, 2roller lock configuration.
