Quick Checks (60 Seconds)

Before calling an engineer, these basic checks solve many “no heat” situations:

1. Check your fuse box: a tripped breaker can look like a boiler failure.
2. Check thermostat and timer: settings can reset after power cuts; replace batteries in wireless controls.
3. Check system pressure (if applicable): if the gauge shows low pressure, follow our pressure guide before calling.
4. Reset once only: if it locks out again after resetting, stop and call us.

The Reality About Hoval Boilers

Hoval is a Swiss manufacturer specialising in commercial and industrial heating systems. Their products are designed for larger buildings – offices, schools, apartment blocks, and industrial premises – rather than typical domestic homes.

If you have a Hoval boiler in a residential property, it was likely installed because:

• The property is larger than average with high heating or hot water demands
• The building was converted from commercial use
• It was specified by a commercial contractor during construction

This creates some practical challenges:

• Specialist knowledge required: Hoval systems need engineers familiar with commercial-grade equipment and controls.
• Parts sourcing: as a Swiss manufacturer with limited UK domestic presence, parts can be difficult and expensive to obtain.
• Repair economics: commercial components cost significantly more than domestic equivalents.
• Right-sizing opportunity: many properties with oversized commercial boilers could run more efficiently on a properly specified domestic system.

Our honest view: if your Hoval has failed and you’re facing expensive repairs, replacement with a correctly sized modern boiler is usually the smarter long-term investment.

What Happens When You Call Us

Here’s our approach to Hoval boiler enquiries:

1. We understand the problem: what symptoms are you experiencing (no heat, no hot water, error codes, leaking, unusual noises)?
2. We identify your setup: Hoval model, age, and how it’s being used in your property.
3. We give you a straight answer: whether repair is feasible or likely to be uneconomic given parts availability and costs.
4. If replacement makes sense: we assess whether a domestic boiler would suit your property or if you need a commercial-grade replacement.
5. You decide: no pressure, just honest guidance to help you make the right choice.

Why Hoval Units End Up in London Homes

We occasionally encounter Hoval boilers in London domestic properties. Common scenarios:

• Warehouse and office conversions: commercial heating was already installed and left in place.
• Large period properties: specified when the heating demand seemed to require commercial equipment.
• New builds with commercial contractors: the installer used familiar commercial brands.
• Mixed-use buildings: shared heating systems serving residential and commercial spaces.

In many cases, modern domestic boilers can now handle these properties more efficiently and economically.

Repair vs Replace: The Numbers

Commercial-grade boiler repairs can be expensive, and the economics rarely favour repair on aging equipment.

Example repair scenario (illustration only): Diagnosis, parts sourcing, and repair on a commercial Hoval unit could easily reach £600-800+ depending on the fault.

• Parts may need to be imported or sourced from specialist suppliers.
• Labour rates for commercial equipment are typically higher.
• Another component could fail within months on an aging system.
• No meaningful warranty on old equipment.

Compare that to replacement: A new domestic boiler installation from £1,899 (or a tailored quote for larger properties) gives you warranty-backed reliability and straightforward ongoing maintenance.

Landlords: Commercial Boilers Create Extra Headaches

If you’re a landlord with a Hoval or other commercial boiler in a rental property, replacement usually makes sound business sense:

• Tenant complaints: commercial systems can be temperamental, leading to more call-outs and unhappy tenants.
• Repair costs: emergency repairs on commercial equipment are rarely cheap.
• Finding engineers: not every Gas Safe engineer is comfortable working on commercial systems.
• Compliance simplicity: mainstream domestic boilers are easier to service and certify.

We support landlords across London with Gas Safety Certificates (CP12) and practical heating upgrades. See our London landlord checklist.
