Reactive Work
Each trade below covers three kinds of work
Emergency
Compliance
Planned
Electrical
Faults, repairs, alterations and compliance work, in homes, offices and commercial premises.
Gas
Boiler faults, servicing and gas safety work, always attended by a Gas Safe registered engineer.
Plumbing
Leaks, blockages and general plumbing repairs, in domestic and commercial settings.
Drainage
Blocked or damaged drains, attended and resolved as a callout.
General repairs
Day-to-day maintenance and small jobs that don't need a full project.
Planned & compliance: landlord and managing agent obligations
These are legal obligations rather than optional repairs, planned to a statutory timetable rather than triggered by a fault, so they sit in their own clearly labelled section rather than inside each trade above. Managing a portfolio, or a single high-value address? Get in touch to discuss a scheduled compliance arrangement across multiple properties.
Gas Safety Certificate (CP12)
Landlords with a gas appliance in a tenanted property are legally required to renew this certificate every 12 months, issued by a Gas Safe registered engineer. A copy must go to the tenant, and non-compliance carries significant fines.
Enquire
Electrical Installation Condition Report (EICR)
Landlords in England must have an EICR carried out at least every five years, or at each change of tenancy. C1 means danger is present and must be addressed before a satisfactory certificate can be issued; C2 means a fault is potentially dangerous and needs urgent remedial work; C3 is a recommendation for improvement and doesn't block a satisfactory certificate; FI means further investigation is needed.
Enquire
PAT testing
Portable appliance testing confirms electrical appliances remain safe for continued use. It's required annually for furnished rental properties and commercial premises.
