Kastel — Prime Lettings

Twelve years finding London's finest addresses.

Kastel is a private lettings practice built on nearly twelve years placing tenants across London's most established neighbourhoods — from Hampstead to Kensington and beyond — for a smaller number of properties done right.

One point of contact. Selected properties. More attention.

Matching what a landlord needs from a tenant, and what a tenant needs from a home.

I've done this long enough to know what actually protects a landlord's property and income — and long enough to know what doesn't. Kastel is the version built on that.

Twelve years, two boroughs, and a deliberately small number of properties at any time — so nothing is ever rushed.

Independent by design

No corporate quota, no branch targets. Every instruction is handled by me, personally.

Selective portfolio

A deliberately limited number of properties, so nothing is ever rushed.

Discreet by default

Off-market matching for landlords who'd rather not be on every portal.

Currently let by Kastel

A small, current selection. Full portfolio on the listings page.

Two ways to let, done properly

A standard tenancy, or a short and mid-term strategy — both run personally.

Private Lettings

Fully managed tenancies — valuation through to renewal, handled by one person, start to finish.

FULLY MANAGED

Short & Mid-Term

Guest and short-let management, run personally rather than through a volume platform.

What landlords say

Real words from real instructions — added as tenancies complete, not written in advance.

Kastel is still building its record of managed tenancies. The first testimonials will appear here directly from landlords once instructions have run their course — nothing's added before then.

Straight answers, written down

Practical guidance for landlords — not portal filler.
