We guide you through every step — from your first property assessment through to installation — with no pressure, no jargon, and no surprises on cost.
Sailax Global is a UK sustainability company specialising in coordinating air source heat pump upgrades for homeowners. We don't just sell systems — we take ownership of the whole process, from your first enquiry through to a fully commissioned installation.
We work exclusively with MCS-certified installation partners, so every job meets the standard required for Boiler Upgrade Scheme grant eligibility. That means the grant is applied directly to your quote — you never have to chase it yourself.
Our approach is simple: give you honest, clear information, confirm what you're eligible for, and only move forward when you're ready. No obligation until you choose to proceed.
Every installation is carried out by an accredited MCS partner — a requirement for BUS grant eligibility.
Your installer applies for the Boiler Upgrade Scheme grant on your behalf. It's deducted from your quote upfront.
We work exclusively with homeowners across England and Wales. Not commercial. Not overseas. Just UK homes.
What we quote is what you pay. The BUS grant is already applied. No hidden costs at installation.
A heat pump doesn't burn fuel — it moves heat. It extracts warmth already present in the outside air and upgrades it to a useful temperature using a refrigerant and compressor, then circulates it through your home.
The outdoor unit draws in outside air — even at temperatures as low as −15°C — and extracts the heat energy held within it using a refrigerant.
The refrigerant is compressed, which significantly raises its temperature — the same principle as how a bicycle pump heats up when you pump it fast.
The heat passes through a heat exchanger into the water in your home's central heating circuit, raising it to your required flow temperature.
Heated water flows through your radiators or underfloor heating, and is stored in a hot water cylinder for taps and showers throughout the home.
What's installed
Every installation covers the full system from the outdoor unit to hot water at your taps. Nothing is left half-done.
Check eligibility in under two minutes. No obligation — just clear, honest information about your property.
