Security matters. Learn how we work to keep your home and family safe.

We use trusted suppliers

Peace of mind starts with high-quality products. That's why we only work with trusted suppliers that have proven security track records.

We use Yale locks for doors

Yale is the world's leading lock brand. To ensure exceptional security, we use Yale door locks in all our residential, composite and French doors.

We use multipoint window locks

All our uPVC and aluminium casement windows feature a highly secure multipoint reverse-action inline locking system.

Why choose Yale?

Yale is one of the world's oldest – and best – lock manufacturers.


Chances are, you know Yale. There's a good reason its locks are recognised the world over – they're among the best money can buy.


At Calder Windows, we always choose superior quality – especially when your home security is at stake. That's why we use Yale door locks for all our residential, composite and French doors. 


At the heart of each Yale lock is a precision-engineered euro cylinder. This strengthened, highly secure component is effective against all common burglary methods – including snapping, bumping, picking and drilling.

3-star rated

The highest security rating available in the UK.

Secured by Design

Our Yale locks are officially recognised by the UK police force.

Anti-snap guarantee

Yale will provide £1,000 compensation if a cylinder is snapped during a break-in attempt.

Words from happy customers

The Yale £1,000 guarantee

A little extra peace of mind.


Yale knows its door locks are secure. Its products are regularly tested by independent locksmiths and security professionals to ensure exceptional strength and resilience.


In fact, it's so confident that it offers a £1,000 guarantee on all 3-star euro cylinder locks.


That's right. In the unlikely event that your cylinder is snapped during a forced break-in, Yale will give you a whopping £1,000 in compensation.
