Who we are

Who we are and how we think

Harvey W James are London Rental Analysts. We track the rental market continuously — three years of Rightmove and Zoopla listing-and-enquiry data, cross-referenced against our own portfolio of recent lettings across London — and we use that evidence to price, market, and manage properties with a precision generic agents cannot match. Where most agencies open with “trust us, we know the market”, we open by showing you the data. Headlines and intros on this site read like an analyst’s report because that is what they are.

We restructured our operating model, our fee architecture, our tenancy agreements, our rent-review process and our possession-handling protocol against the Renters’ Rights Act 2025 before it came into force on 1 May 2026. The 85-section Essential Terms and Charges document (v2.1.5, 7 May 2026) that underwrites every page on this site is fully RRA-aligned. For landlords, the practical implication is that the marketing price you set on day one is now, in functional terms, the price for the life of the tenancy — and that single decision matters more than any other operational choice you will make. Our job is to make sure that decision is the right one.

We are also new-build specialists. Our experience managing a diverse range of new-build units across London has furnished us with operational insights generic letting agents do not have, and that landlords with new-build portfolios actually need: communal heating and prepayment meters, snagging coordination, developer handover, first-let pricing in thin-comparable environments, block-level marketing competition. We work with new-build landlords through our new-build specialists service.

What we do differently

The five things we do differently

Five things separate our operating model from a generic letting agency. None of them are marketing lines; each is a defensible, evidenced position drawn from documents we publish and maintain.

We are analysts, not agents.

Our valuations are built on three years of Rightmove and Zoopla listing-and-enquiry data, supplemented by our own portfolio evidence. We track days-on-market, enquiry-to-listing ratios, monthly demand cycles, and day-of-week launch performance. When we tell a landlord their property should be marketed at a given price with launch on a Monday in the third week of August, we can show them the analysis behind every component of that recommendation.

Three years of Rightmove & Zoopla data

We specialise in new-builds.

Our experience managing a diverse range of new-build units across London has furnished us with insights generic letting agents do not have — and that landlords with new-build portfolios actually need. New-build lettings have commercial differences (block-level marketing competition, thin comparable evidence on first-let), operational differences (developer handover and snagging, communal heating and prepayment meters), and portfolio differences (service charges, ground rent, Section 20 consultation, NHBC defect coordination).

Our timing intelligence is data-backed.

We do not say “spring is busy”. We say August has the highest enquiries-to-listings ratio of any month in our dataset, the third and fourth weeks of a month draw 5–10% more enquiries than the first two, Monday morning is the optimal advert-launch slot, and the Four Week Rule — advertising more than four weeks before the available date destroys a listing’s prime position — is the single biggest pricing-adjacent mistake we see landlords make.

We engineer the post-RRA letting cycle.

Other agents will tell you fixed terms are gone under the RRA, so there is nothing you can do about timing. That is the wrong answer. Fixed terms are gone, but the August demand peak is not. Our Assisted Tenancy Replacement Process (ETC §68.1) is built to land re-lets on the demand peak even under the periodic regime — by sequencing tenant communications, valuation refreshes, marketing launches, and viewing windows around the months when enquiry volume is highest. The cycle is the asset; the fixed term was the scaffolding.

We have been RRA-ready since day one.

The Renters’ Rights Act 2025 is not a thing we are preparing for. It is the thing we have already absorbed, structured around, and engineered against. Essential Terms and Charges v2.1.5 (7 May 2026) is fully RRA-aligned. Our possession-handling protocols, our rent-review templates (Section 13 and Form 4A), and our compliance tracking for the PRS Database, the PRS Ombudsman, and Awaab’s Law are documented and operational. We are forward-looking on Awaab’s Law (expected in the PRS from 2027) and the Decent Homes Standard (PRS from 2035) as well.

If you are a landlord, the landlord page sets out our service tiers, our 10% fee architecture with early-exit catch-up, and our Renters’ Rights Act 2025 operational pitch in detail. If you are a tenant or applicant, the tenants page explains your rights and how the application and tenancy lifecycle works under the Act. The Renters’ Rights Act 2025 hub is the legal-and-operational reference that underpins both.
