Maintenance contracts for businesses.Planned maintenance, one report, priority line.
Annual maintenance contracts for site managements, offices, shops and small businesses: a pre-season maintenance calendar for boilers, air conditioners, water heaters and pipework, fixed price, appliance inventory, one report and priority service when something fails.
FOR BUSINESSES
Instead of calling forty flats one by one: one calendar, one contact, one report.
Forty boilers in a residential site, twelve air conditioners on an office floor, three VRF indoor units in a shop… Managing their maintenance call by call is expensive and untraceable. A maintenance contract puts every appliance in one inventory, ties pre-season maintenance to a calendar and gives you a single contact all year.
What the contract covers
- Appliance inventory — brand, model, serial number, location and service history of every unit
- Pre-season planned maintenance — boilers in September–October, air conditioners in April–May; dates and time windows planned with the management
- Fixed annual fee — by appliance count; budgetable, no surprises
- One report — per-appliance report after each round: work done, readings, recommended replacements
- Priority fault line — priority scheduling and discounted labour for contract customers
- Parts policy — genuine parts, written guarantee; replacements only after approval
Who it is for
- Site managements — individual boilers or central plant; we coordinate appointments with residents
- Offices and towers — split, multi-split and VRF maintenance, filter and coil cleaning
- Shops and chains — one contract for all branches, a standard maintenance form
- Schools, nurseries, clinics — maintenance planned into holiday periods
How we start
- On-site survey — appliance count, current condition, at-risk units
- Quote — annual fee per appliance, scope and calendar
- Contract — one year, scope and price in writing
- First maintenance round and inventory report
- Fault calls through the year, priority call-out, end-of-term review

FAQ
About maintenance contracts.
Is there a minimum number of appliances?
No fixed minimum — from an office's 5 air conditioners to a site's 60 boilers. The price scales with appliance count.
Does the contract cover repairs?
The standard contract covers planned maintenance; faults get priority call-out and discounted labour, parts priced separately. A 'parts included' scope can be quoted on request.
Who arranges appointments with residents?
We do. We take the flat list from the management, build a block-by-block calendar and notify every flat in advance; a follow-up round is planned for flats missed.
Do you maintain central plant boilers?
Central plant and boiler-room maintenance can be included after a survey; we inspect on site before quoting.
How is the service fee set?
After diagnosis, the work and any part cost are quoted clearly before we start. Nothing is done without your approval.
