III · STANDARDS

How we work, and why it matters.

Twenty-five minute response.

We work from St James's Street. The clock starts when you call. We do not subcontract emergency calls to drivers in unrelated postcodes.

Non-destructive entry, where possible.

Most lockouts are resolved without damage to the cylinder. Where a lock must be drilled, we explain it on the doorstep, before any tool touches the door.

DBS-checked engineers.

Every engineer carries identification and a DBS check. You will be told the engineer's name before they arrive.

Work guaranteed in writing.

Parts and workmanship covered for twelve months. A clear written invoice, every time.

IV · REVIEWS

What clients have said.

Snapped key in the front door at eleven on a Tuesday night. The engineer was on the doorstep in twenty minutes, opened the cylinder without a scratch, and replaced it the same hour.
H. Whitford, St James's
We needed a restricted-key system across three doors of a listed townhouse. Avelios specified, sourced and fitted everything in a single afternoon, with no fuss and a clean, written quote afterwards.
A. Mehta, Belgravia
Burglary on a Sunday morning. They boarded the door within the hour and returned the following day to fit a full new lock specification. Considered, professional, and discreet throughout.
