Lettings apps for London agents juggling 33 councils and one rent roll.

Property management app development London letting agents and portfolio landlords can run their week on. We build the tenant app, the landlord portal and the office dashboard that hold deposits, Right to Rent checks, gas and electrical certificates, borough licences and rent collection in one place, so a lettings team covering Hackney, Wandsworth and Ealing works from a single record instead of three spreadsheets and a shared inbox.

London lettings carry more paperwork per door than almost anywhere else in England. Every borough sets its own licensing rules, many tenants hold eVisas rather than paper documents, and a large share of landlords live abroad. The app is planned around those facts from the first workshop call.

What a London lettings app needs

Built for the compliance load of letting in the capital.

A London lettings team rarely loses a tenancy because of marketing. It loses time, money and sometimes the right to collect rent because a borough licence lapsed, a deposit certificate was not served, or a Right to Rent follow up check was missed for a tenant on a time limited visa. The capabilities below are the ones London agents ask for most often, ordered roughly by how much risk they remove. Each one sits on a shared tenancy record so that when a tenant moves from Lewisham to Barnet, or a landlord adds a flat in Croydon, nothing has to be typed twice. We keep the tenant side simple enough to use on a phone on the Tube, and the office side detailed enough for a compliance manager who answers to a redress scheme and, in some boroughs, a licensing officer with powers to issue civil penalties.

Explain your project
  • Borough licence register

    Each property is tagged with its borough and ward, the licensing scheme that applies (mandatory HMO, additional or selective), the licence number, conditions and expiry. Newham, for example, runs selective licensing across most of its wards, while neighbouring boroughs draw the lines differently. The register flags homes that move into a new designation.

    No flat is let in a licensing area without a licence on file.

  • Right to Rent with share codes

    Many London applicants prove their status with a Home Office share code rather than a passport. The app records the online check, stores the result against the tenancy and schedules the follow up check for anyone with time limited permission, so the reminder reaches the right negotiator before the permission ends.

    Follow up checks happen on time, with evidence stored.

  • Deposit protection and prescribed information

    Deposits are registered with your chosen government approved scheme, the certificate and prescribed information are served through the tenant app, and the date of service is logged. At the end of the tenancy, the check out report and proposed deductions sit in the same thread the tenant can see.

    A clean evidence trail if a deposit is ever disputed.

  • Overseas landlord statements

    London has a high share of landlords living outside the UK. Statements can show tax deducted under the HMRC Non Resident Landlord Scheme where no approval is held, record approval numbers where it is, and produce the quarterly and annual figures your accounts team needs.

    Overseas owners get statements their accountants can use.

  • Certificate tracker for each flat

    Gas safety records, electrical installation condition reports, EPCs, smoke and carbon monoxide alarm checks and fire risk notes for HMOs are stored per property with expiry dates. Engineers upload directly, and tenants receive a copy through the app inside the period the rules require.

    Expired certificates show up weeks before they cause trouble.

  • Pay by bank rent collection

    Rent can be paid through Open Banking payment links or collected by Direct Debit, with card as a fallback. Receipts post to the tenant ledger automatically, arrears follow a reminder sequence you approve, and the landlord sees cleared funds rather than promises on their statement.

    Less manual reconciliation at month end.

  • Applications, referencing and holding deposits

    Applicants apply on their phone, upload ID and income evidence, and consent to referencing in one flow. Holding deposits are capped and tracked against the deadline for agreement, with automatic prompts if the deadline is close. Because asking prices can no longer be bid up, the app records the advertised rent and stops staff accepting higher offers.

    Faster offers that stay within the Tenant Fees Act and the bidding ban.

  • Repairs with access and parking notes

    Tenants report a fault with photos and choose access times. Contractors see the entry instructions, the concierge or key safe details, controlled parking zone notes and whether the van needs to meet ULEZ standards, which matters to firms sending trades from outside the zone.

    Fewer wasted visits across London traffic.

  • Block and freeholder coordination

    For buy to let flats inside managed blocks, the app records the block's managing agent, the communal repair route and who holds the buildings insurance. A leak from a communal pipe gets routed to the freeholder's agent, not your contractor.

    Communal faults reach the party who is responsible.

  • Rent review and notice workflow

    Under the Renters' Rights Act rules that began in May 2026, rent increases follow the statutory notice route, no more than once a year. The app drafts the notice from the tenancy record, logs service and tracks any challenge, so London's frequent rent reviews stay inside the law.

    Every increase is served correctly and on record.

Who this is for

Four London lettings businesses we build for.

The right first release depends on what is hurting most today. A high street agency with fifteen hundred managed doors needs different tools from a family office with forty flats in Marylebone, and a build to rent operator in Stratford has different pressure again. These are the starting points we hear about most often from London firms, and how we would shape the first version for each. Some clients come to us for tenant management app development London tenants will find easy; others want a rental property management app development London owners can see from abroad. The plan changes with the brief.

01

Multi branch agencies working across several boroughs

Branches in, say, Islington, Clapham and Ealing often run the same software in slightly different ways. We standardise the tenancy record, give each branch its own view and build a single compliance dashboard for the head of lettings. Borough licensing data is held centrally so a branch manager cannot miss a designation that changed while they were busy with renewals.

One record per tenancy, many branch views.

02

Landlords with portfolios owned from abroad

Owners based in Hong Kong, Dubai, Lagos or New York want to see rent, arrears, certificates and repair spend without phoning London. A landlord portal with clear statements, tax deductions shown line by line and document access cuts the volume of emails your accounts team handles every month.

Fewer time zone emails for your office.

03

Build to rent and single family rental operators

Operators in places such as Wembley Park or Stratford let hundreds of homes under one brand. They need fast online applications, referencing, move in scheduling and renewals at scale. We connect the lettings side to whatever resident app already exists rather than rebuilding amenity booking.

04

Agents replacing an ageing desktop system

Some London agents still run on software that has no tenant app and no open API. We plan the migration of tenancies, ledgers and documents, run old and new side by side for a period you choose, and only switch off the legacy system once the reconciliation matches.

How a London lettings app goes from first call to live.

  1. 01Discovery by video callWe map your boroughs, licensing exposure, landlord types and current software. Every decision is written up after the call so directors who missed it can catch up.
  2. 02Compliance mapDeposits, Right to Rent, certificates, licences and notices are turned into rules with owners and deadlines, checked against your redress scheme and client money protection obligations.
  3. 03Design for three audiencesTenant, landlord and staff screens are designed separately, tested with real negotiators, and kept accessible to WCAG 2.2 so tenants using screen readers can still report a repair.
  4. 04Build and integrationsWe connect payments, referencing, deposit schemes and accounting through their published interfaces, and keep a test environment where your team can try every flow before release.
  5. 05Migration and parallel runningTenancies, ledgers and documents move across in batches. Balances are reconciled before each cut over, and nothing is deleted from the old system until you sign off.
  6. 06Launch and steady improvementStaff go live first, tenants and landlords follow in waves. After launch we track support tickets and adjust the screens people struggle with.

Technology

What we build this with.

Tenant and landlord apps are built for iOS and Android from one codebase, with a web dashboard for staff. Data is hosted in a UK or EU cloud region agreed with you, with access controls and audit logs to support your UK GDPR obligations. Notifications go by push, email and SMS depending on what the tenant chooses.

Questions London agents ask before commissioning an app.

It depends mostly on how many systems you need to migrate from and connect to.

A London agent replacing spreadsheets has a shorter path than one moving years of ledgers out of an older lettings platform. Borough licensing data, deposit scheme connections and payment set up also add time. We agree a timeline once discovery has shown us your data and integrations, write it into the scope, and report progress against it at every sprint demo. If the scope changes, the timeline is updated in writing before work continues.
