London property, held for the long term

We acquire and hold residential properties for long-term letting, manage homes for landlords, and provide specialist business consulting.

Acquiring residential properties across London and the wider UK.

What we do

Buy-to-let investment

We acquire residential properties across London and the wider UK for long-term holding and letting. Our business model is built on generating stable rental income over many years rather than short-term resale, and that principle guides every decision we make—from the types of properties we purchase to the structure of the tenancies we offer.

How we work

We hold what we buy

Primekey is a special purpose vehicle registered under SIC code 68209, letting and operating our own property. We are not developers and we are not traders. That is a deliberate choice and it is visible on the public record.

Void months cost more than repairs

A good tenant who stays is worth more than a rent rise that pushes them out. We fix things quickly because it is cheaper than re-letting.

Compliance is not paperwork

Gas safety, electrical condition reports, energy performance, deposit protection, right to rent. Each one has a penalty attached and a date it falls due. We track them so landlords do not have to.

You should know what your property is doing

Statements you can read without a phone call, and a named person who answers when you ring.

Who we work with

Landlords with one or two properties who have run out of patience with self-managing.

Portfolio landlords bringing management under one roof.

Owners living abroad who need someone in the country.

Investors weighing up whether to hold personally or through a company.
