London Landlord Property Maintenance: Annual Calendar and Legal Obligations
A comprehensive calendar of property maintenance obligations for London landlords — what must be done legally, what is best practice, and how to manage it efficiently across a property portfolio.
London Landlord Legal Maintenance Obligations
London landlords operate under a more complex regulatory framework than many UK regions, with the GLA, London boroughs and national regulation all playing a role. Here is the full landscape of maintenance obligations:
Annual Requirements
- Gas safety inspection (CP12) — every 12 months, all gas appliances
- Smoke alarm test — at the start of each tenancy (landlord responsibility to test, not just fit)
- Carbon monoxide alarm — required in rooms with a fixed combustion appliance (boiler room, room with gas fire)
5-Year or Change-of-Tenancy Requirements
- EICR (Electrical Installation Condition Report) — every 5 years or at change of tenancy
- Legionella risk assessment — periodic review recommended, more frequent for HMOs
Ongoing Requirements
- Structural repairs (roof, walls, windows) — keep in good repair
- Heating and hot water — keep in proper working order (24/7/365)
- Plumbing (pipes, drains, sanitation) — keep in good repair
- EPC — required on marketing; currently minimum E, proposed C by 2028
An Annual Maintenance Calendar for London Landlords
September / October — annual gas safety inspection and boiler service combined visit. Best to do before winter demand peaks and engineer availability tightens.
November — check condensate pipes (vulnerable to freezing in winter). Insulate any external sections.
January / February — respond to any winter heating complaints. Emergency engineer on speed dial for coldest months.
April — EICR due? Check certificate date. Schedule testing for summer when properties may be easier to access.
June / July / August — minor works and redecoration between tenancies. Ideal window for planned plumbing upgrades.
Frequently asked questions
How much does annual property maintenance cost for a London buy-to-let property?
A rough annual maintenance budget for a typical London buy-to-let 2-bedroom flat: Gas safety inspection + boiler service £100–£180; boiler repair contingency (amortised) £80–£150; EICR (annualised over 5 years) £30–£60; minor plumbing repairs £100–£300; general maintenance (locks, appliances) £100–£200. Total: approximately £400–£800 per year for a well-maintained flat. HMOs and houses require higher budgets. London landlords should budget 1–2% of property value per year for maintenance.
Can I use one company for all compliance and maintenance at a London rental property?
Yes — using a single company for gas safety, EICR, PAT testing, boiler service and general plumbing maintenance has advantages: one relationship to manage, consolidated invoicing, engineers who know the property, and combined visit savings (one call-out for multiple services). For London landlord portfolios of 3+ properties, a preferred supplier agreement with a maintenance company typically delivers better value than using separate specialists for each certificate type.
When must a London landlord carry out repairs after a tenant reports them?
There is no single statutory timescale for all repairs in London rental properties. Emergency repairs (heating and hot water failure, serious leak, structural danger) should be addressed within 24–48 hours. Urgent but non-emergency repairs (minor leaks, faulty locks, boiler intermittently working) within 7–14 days. Non-urgent repairs (cosmetic issues, minor dripping taps) within 28 days. Local authorities can serve Improvement Notices on landlords with persistent disrepair — the notice specifies a deadline for compliance.
