What's the difference between a 3-lever and a 5-lever lock?

A 5-lever mortice lock meets BS3621 — the British Standard most home insurers require on external doors. 3-lever is fine for internal doors but won't satisfy a home-insurance check.

How long does a lock change take?

A like-for-like cylinder swap is usually 20 minutes. A new 5-lever mortice lock — including chiselling out the door if needed — is typically 60 to 90 minutes.

Do you have stock on the van?

Yes. We carry the standard insurance-rated mortice locks, euro cylinders in all common sizes, and a handful of nightlatches. Most residential jobs are done the same call.

Will you tidy up after?

Always. Old hardware bagged and disposed of, door checked for free movement, keys handed over with a quick rundown of how the new lock works.
