If you’re a social housing tenant, boilers and Heat-Interface Units (HIU) usually come with specific responsibilities and limits. Here’s what’s worth keeping in mind:
1. When you have a boiler inside your home
Responsibility and permissions
The landlord/ SHA is normally responsible for:
- Annual servicing
- Safety checks (gas safety certificates)
- Repairs and replacement
You should not:
- Attempt repairs yourself
- Hire your own engineer without written permission (you could be liable for damage)
Safety basics
- Know where the isolation switch / gas shut-off is.
- Keep the area around the boiler clear and ventilated.
- Never block flues or air vents.
Report immediately if you notice:
- Gas smells – further instructions given below*
- Carbon monoxide alarm sounding
- Soot, scorch marks, or unusual noises
Reporting problems
- Report faults early (no heat, no hot water, pressure loss, leaks).
- Use the landlord’s official report a repair portal, so it’s logged.
- Emergency repairs (e.g. no heat in winter) usually have faster response times.
Day-to-day use
Ask for guidance on:
- Thermostat settings
- Timer/programmer use
- Over-pressurising or constantly resetting faults can cause more damage—better to report recurring issues.
2. When you have a Heat-Interface Unit (HIU)
HIUs act as a bridge between a central boiler/heat source and your home’s radiators and taps. They provide instantaneous heating and hot water, replacing a traditional gas boiler.
Responsibility and permissions
How to use it properly
- Do not turn it off unless advised – it’s designed to run continuously.
- Use boost settings only when needed (showers, cooking).
Tenant maintenance
Keep vents unobstructed – do not cover with furniture, tape or any kind of covering.
What not to do
- Don’t tamper with internal settings.
- Don’t disconnect power to “save money” – this can cause damp and mould; poor air quality and damage to the system.
Report these issues
- Excessive noise or vibration
- Persistent condensation or mould (even when using the system)
- Unit not running or showing fault lights
Things residents often forget (but should not)
- Let contractors access your home in a timely manner for mandatory inspections – refusal can breach your tenancy terms.
- Report small issues early (drips, odd sounds) before they become major.
- Ask for clear instructions – if unsure, ask about any unfamiliar systems.
If you’re unsure
If something isn’t explained well (especially HIUs, which many tenants aren’t familiar with), you can:
- Request written guidance from your SHA or SHA contractors
- Ask whether filter cleaning is your responsibility or theirs
- If you have any questions on anything relating to boilers and HIUs, call or email to speak with an SHA officer today.
*If you smell gas in the UK – act quickly:
What to do
- Don’t use switches, flames, or phones indoors
- Open windows/doors if safe
- Turn off the gas supply at the meter
- Leave the property immediately (take others and pets)
- Call for help (from outside) – Call the : 0800 111 999 (UK National Gas Emergency Service)
- Gas smells like rotten eggs / sulfur
Only return to your home when told it’s safe.
That’s it – get out, stay out, and call.
