Boiler installs for a HMO (House in Multiple Occupation)
Licensed and non-licensed HMOs across Harlow, Epping and Hoddesdon — a growing share of our commercial repair work. We do a steady stream of boiler installations across HMO (House in Multiple Occupation)s in West Essex and East Herts. HMO installations are usually about right-sizing the hot-water system — a single combi rarely keeps up with 5+ tenants. We spec system boilers with correctly-sized cylinders.

HMO (House in Multiple Occupation)-specific issues we see
- Extra CP12 requirements — annual for every gas appliance, plus interlinked CO alarms
- Higher hot-water demand than family homes — most single combis are undersized
- Boiler in an accessible location required by most council HMO licenses
- Frequent tenant turnover means more wear and tear on controls
Our approach for HMO (House in Multiple Occupation)s
For 5+ bed HMOs we usually recommend a system boiler with a well-sized cylinder — a combi simply can't keep up with morning shower peaks. Cheaper long-term than repeated combi replacements.
How an HMO install runs
- Peak-demand calculation done properly — not a guess
- System boiler + unvented cylinder specified where combi can't cope
- Interlinked CO alarms fitted on every gas-appliance floor
- CP12 issued same day, tenant notice managed
Typical timing
2-3 days for a full system change in a 5-6 bed HMO — cylinder swap, controls, cabling. Planned around tenant turnover where possible.

Frequently asked questions
Do HMOs need a different CP12?▾
Same certificate, but Essex and Herts councils often require every appliance to be tested and interlinked CO alarms in place. We handle both.
Can we get a landlord service contract?▾
Yes — we run rolling annual contracts for local HMO landlords with priority response and portfolio pricing.
Combi vs system boiler for a 6-bed HMO?▾
Nearly always system + cylinder. Combi peak demand can't handle three simultaneous showers.
Do you handle the HMO licence paperwork?▾
Yes — we provide the CP12, CO-alarm certificate and boiler service records the council wants.
