The Ultimate Property Maintenance Checklist for London Landlords in 2025
Why Every London Landlord Needs a Maintenance Plan
Owning property in London is a valuable investment, but it also comes with ongoing responsibility. From emergency repairs to planned maintenance, keeping your property in excellent condition is essential for protecting tenants, complying with regulations, and maintaining long-term value.

At QBS Property Maintenance, we work with landlords and property managers across North, South, East, and West London to provide reliable maintenance and repair services. This guide outlines a comprehensive checklist designed to keep your properties compliant, efficient, and profitable throughout 2025.
1. Plumbing and Water Systems
Regular plumbing maintenance helps prevent costly water damage and ensures your property runs efficiently.
- Inspect for leaks under sinks, around toilets, and along visible pipes.
- Service taps and showers to remove limescale, which is common in London’s hard-water areas.
- Flush radiators annually to improve heating performance.
- Check water pressure and make sure tenants know where the stopcock is located.
Professional plumbing inspections can save thousands in emergency call-outs later. QBS Property Maintenance provides full plumbing checks, repairs, and emergency services across London.
2. Electrical Safety and Appliances
Electrical safety is a legal requirement for all landlords. Faulty wiring or neglected systems can lead to serious hazards and fines.
- Arrange an Electrical Installation Condition Report (EICR) at least every five years.
- Test smoke alarms and carbon monoxide detectors regularly.
- Inspect appliances for damage, especially older or high-usage ones.
- Replace faulty plugs, sockets, or wiring immediately.
Always use a certified electrician for repairs or inspections. The QBS electrical team is fully qualified to handle landlord compliance checks and emergency call-outs.
3. Gas and Heating Systems
Safe heating systems are essential for tenant comfort and legal compliance.
- Book your annual Gas Safety Certificate (CP12) before the cold season begins.
- Schedule a full boiler service annually to maintain efficiency and reduce breakdowns.
- Check ventilation in boiler rooms and ensure flues are clear of obstructions.
QBS employs Gas Safe-registered engineers who carry out installations, servicing, and emergency heating repairs across all London boroughs.
4. Roofing and Guttering
Minor roofing issues can escalate into expensive structural repairs if ignored. Regular roof checks are one of the best long-term investments a landlord can make.
- Inspect roofs and gutters at least twice a year.
- Clear leaves, moss, and debris to prevent damp and leaks.
- Repair damaged tiles, flashing, or gutter joints promptly.
QBS Property Maintenance provides professional roofing inspections and emergency repair services throughout Greater London.
5. General Property Upkeep
Routine upkeep keeps your property attractive to tenants and helps preserve its value.
- Repaint walls, ceilings, and woodwork every few years.
- Replace flooring or carpets between tenancies if worn or damaged.
- Deep clean kitchens, bathrooms, and common areas regularly.
QBS offers end-of-tenancy cleaning, minor refurbishments, and general repair work to keep properties in prime condition year-round.
6. Seasonal and Compliance Checks
A proactive approach ensures that no critical maintenance task is missed during the year.
Spring: Inspect roofs, drains, and outdoor spaces after winter weather.
Summer: Repaint exteriors, test outdoor lighting, and service air conditioning units.
Autumn: Clean gutters, service heating systems, and check for draughts.
Winter: Inspect insulation, pipes, and heating systems to avoid breakdowns during cold spells.
7. Record Keeping and Legal Compliance
Maintaining proper records is just as important as completing the physical work. Keep all receipts, certificates, and inspection reports organised and up to date. This not only demonstrates compliance but also simplifies future property sales and insurance claims.
QBS provides landlords with detailed service documentation for every job, ensuring you remain compliant with UK property regulations.
