London property apps built for leasehold flats, fast lettings and buyers abroad.

Property app development London, for estate agents, letting agents and new homes sales teams working across the capital's boroughs. We build apps where applicants search by Tube line and commute, see leasehold and building safety details before they book, and make offers or rental applications that your team can verify. Behind them sit a negotiator app and an admin dashboard that keep listings, viewings and compliance checks in one place for every branch.

A London listing has more to explain than most. Lease length, service charge, ground rent, cladding status and the borough's licensing rules can all change a buyer's or tenant's decision, and an app that hides them only creates fall throughs later. We build the app so those facts are part of every listing from day one.

Capabilities

What London agents ask a property app to handle.

London buyers and renters move quickly and compare a lot. A flat in Canary Wharf competes with one in Stratford or Battersea on commute, lease terms and building, not just price per room. Overseas buyers want video viewings and clear paperwork, while renters in a busy market want to apply before someone else does. The features below come from that reality. We usually start with search, listing quality and viewings, then add offers, identity checks and new homes tools, but a prime agency and a high volume lettings agency will order them differently. Everything connects to your agency CRM and your portal feed, so the details a renter sees in the app match what appears on the portals and in your branch window.

Explain your project
  • Commute and transport search

    Applicants draw an area or set a maximum travel time to an office in the City, Canary Wharf or King's Cross, by Tube, Elizabeth line, Overground or bus. Results update as they change the limit, and saved searches notify them the moment a match is listed. Step free access filters help buyers with mobility needs.

    Search that matches how Londoners actually decide where to live.

  • Leasehold details up front

    For leasehold flats the listing shows lease length remaining, service charge, ground rent and any review terms alongside the other material information, so buyers judge the true running cost before they book a viewing. Share of freehold and commonhold are labelled clearly as well. A lease extension in progress can be noted too.

    Fewer sales collapsing when the lease pack arrives.

  • Building safety information

    Many London homes are in taller blocks. The listing record holds building safety notes such as cladding status, EWS1 forms where relevant and fire safety information supplied by the freeholder or managing agent, shown to applicants in plain terms. Higher risk buildings registered with the Building Safety Regulator can be marked as such.

    Buyers and lenders see building safety facts early.

  • Borough licensing records

    Licensing schemes differ from one borough to the next. Each rental carries its borough, any selective, additional or HMO licence number and expiry, and the dashboard warns before a licence lapses. Gas, electrical and EPC certificates sit in the same record. Each record shows who last checked it and when.

    Lettings compliance tracked borough by borough.

  • Video viewings and virtual tours

    Live video viewings booked like any other appointment, plus recorded tours and floor plans, so relocating professionals and overseas buyers can shortlist without flying in. Negotiators can run a live viewing from the flat while the buyer joins from another time zone. Recordings stay private to registered applicants.

    Serious buyers from abroad reach a second viewing faster.

  • Rental applications at fixed rents

    Tenants apply to the advertised rent only, as the Renters' Rights Act requires, with referencing, Right to Rent checks through GOV.UK share codes or certified digital identity, and a holding deposit taken in the app. Landlords approve tenants from their own login. Applicants see a clear list of permitted payments.

    Fast, fair applications in a competitive rental market.

  • Buyer verification and AML

    Identity checks, source of funds and source of wealth questions for buyers and sellers, including those funding a purchase from overseas, with documents stored securely against the transaction for your HMRC supervised AML records. Company and trust buyers get extra steps for beneficial ownership. Solicitors receive a verified summary.

    Cleaner files for compliance and for solicitors.

  • Off plan launch tools

    For new developments in areas such as Nine Elms, Wembley Park or the Royal Docks, the app shows availability by floor and aspect, holds reservations, and sends each buyer their documents and build updates until completion. Investor buyers can track several units in one account.

    A launch team that can sell a block, not one flat at a time.

  • Multilingual listing pages

    Listing summaries and key information in the languages your buyers use, with English as the binding version, so international clients understand tenure, costs and timelines without relying on a third party. Translations are prepared for key fields, such as service charge and lease terms, where misunderstanding is most costly, and reviewed before they go live.

    Clearer conversations with buyers who are not native English speakers.

  • Branch and negotiator dashboard

    Managers see enquiries, viewings, offers and applications by branch and negotiator across London, with response times and stalled sales flagged for follow up. Agencies with outer London and inner London branches can compare them side by side. Lettings and sales pipelines can be viewed separately or together.

    Directors see the whole London pipeline in one view.

Who we build for

Where London property apps make the biggest difference.

The London market rewards speed and punishes surprises. An app is worth building when it shortens the time between a listing going live and a verified offer or application, and when it removes the late surprises about leases, buildings and licences that cause deals to fail. These four kinds of business get the most from it. Smaller teams can start with one part and grow from there. For each of them, we describe the first release we usually recommend and why.

01

High volume lettings agencies

If your branches let hundreds of flats a year across several boroughs, every hour between enquiry and application matters. We build apps where renters book viewings, apply at the advertised rent, upload references and complete Right to Rent checks in one session, while your team sees licences, certificates and deposit status per property. Tenants also see where their application stands, which cuts the calls your lettings desk takes every afternoon. Each step is time stamped so you can show a fair process if an applicant asks.

Speed with a clean compliance file.

02

Prime and international sales teams

Buyers of prime homes in Kensington, Marylebone or Hampstead often live elsewhere for part of the year. They want private listings, video viewings, secure document exchange and clear AML steps. We build discreet apps with invitation only listings and a direct line to their named agent. Family offices and buying agents can be given their own access with the same controls. Sensitive details, such as the seller's identity, stay hidden until the agent releases them. Viewings can be arranged at short notice.

Discretion matters as much as features.

03

Developers and new homes agents

London schemes are often sold off plan over long periods, to owner occupiers and investors in the UK and abroad. We build reservation, document and construction update tools so buyers stay informed until handover and your sales team knows exactly which units remain. Handover snagging and completion notices can sit in the same account, so buyers have one place for every document. Investors buying several units can manage them together in one login. Sales progress for each plot shows in the dashboard.

Built around phases and releases.

04

Independent agents competing with the big brands

A strong independent in Walthamstow, Brixton or Ealing knows its streets better than any national chain. An app with sharp local search, quick viewing booking and honest listings lets that local knowledge show, and keeps registered applicants loyal instead of drifting back to the portals. We keep the build focused so it suits the budget of a one or two branch agency. Branch staff can add listings from a phone straight after a valuation. Vendors get viewing feedback on the same day.

Our six stage process for London property apps.

  1. 01Remote discoveryVideo calls with directors, lettings and sales managers to map your boroughs, your CRM, your portal feed and where deals currently stall or fall through. We also review your current app or website analytics.
  2. 02Data and compliance designWe model leasehold terms, building safety notes, licences, AML status and material information as structured fields, so every listing is checked before it goes live. Your compliance lead approves each rule.
  3. 03Interface designSearch, listing, viewing and application screens designed for quick decisions on a phone during a commute, with accessible layouts that meet WCAG 2.2. Screens are tested with real London listings.
  4. 04Development and integrationApps for iOS and Android plus the negotiator and admin tools, integrated with your CRM, identity provider, referencing partner and payment provider. Each integration is tested against sandbox accounts first.
  5. 05Pilot branchOne London branch uses the app on real listings first. We tune search, notifications and compliance prompts from what that team finds before wider release. Applicants in that branch's patch are invited to try it.
  6. 06Rollout and supportBranch by branch rollout, store publishing, data migration and ongoing releases, with fixes and improvements planned in agreed cycles. Reporting tells you which features London applicants use most. New branches join in agreed waves.

Technology

What we build this with.

We choose the stack around your CRM, your referencing and identity partners and the team who will maintain the app, and we build to UK GDPR with ICO guidance in mind for applicant data. Push notifications, maps and video are chosen for reliability on busy London mobile networks and underground Wi-Fi.

Questions London agencies ask before building.

Applicant app, negotiator app and admin dashboard, linked to your CRM.

The applicant app covers search, saved alerts, listings with full material information, viewings, offers and rental applications. Negotiators get a mobile view of their diary, keys and applicants. The dashboard handles listings, compliance records, branches and reporting. For London we almost always add leasehold and building safety fields, because those are the details that most often derail sales here. Vendor and landlord views, where owners follow feedback and offers on their own homes, are a common second release.
