If you’re considering switching to a low carbon heating system, an air source heat pump is one of the most efficient and future ready options available. Many homeowners are surprised by how straightforward the installation process is, and how little disruption it causes when carried out by an experienced team.
In this article, we’ll walk you through what’s involved in fitting an air source heat pump, how long it typically takes, and how Heat Charge Evolution ensures the process is smooth, professional, and fully tailored to your home. We also explain how we apply for the £9,000 Boiler Upgrade Scheme on your behalf to greatly reduce your installation cost.
What happens when you install an air source heat pump?
Installing an air source heat pump is a structured process designed to ensure efficiency, reliability and long term performance.
Below is the typical step by step approach used by Heat Charge Evolution.
1. The home survey
Every successful installation begins with a detailed home survey. During this visit, we:
• Assess your property’s insulation
• Measure heat loss room by room
• Check radiator sizes and pipework
• Review your hot water needs
• Identify suitable locations for the indoor and outdoor units
This ensures the system is designed specifically for your home, not a one size fits all setup
2. Accurate System Design
Once your survey is complete, we design a bespoke heating system that suits your property’s exact needs. This includes:
• Choosing the right size of heat pump
• Recommending radiator upgrades if needed
• Planning the best layout for efficiency
• Preparing your Boiler Upgrade Scheme application
• Providing a clear, transparent quotation
Nothing is left to guesswork, your system is engineered for precision and comfort.
3. Applying for the Boiler Upgrade Scheme
Heat Charge Evolution handles the entire BUS application for you. We:
• Confirm your eligibility
• Submit all the necessary forms
• Secure the £9,000 grant
• Deduct it directly from your installation cost
You don’t need to deal with any paperwork or government portals, we take care of it all.
4. Installing the outdoor unit
The outdoor unit is positioned in a location with good airflow, typically in the garden, on a side wall, or beside a driveway.
During installation, our engineers:
• Set the unit on a sturdy base or wall mount
• Ensure correct clearances
• Fit all insulated pipes neatly and securely
• Minimise visual impact where possible
We always aim for the quietest, most discreet placement without compromising performance.
5. Installing the indoor equipment
Inside your home, we fit:
• The hot water cylinder (if required)
• System controls and thermostats
• All connecting pipework and valves
If any radiators need upgrading, we complete this work at the same time. We maintain a clean, organised workspace throughout, keeping disruption to a minimum.
6. Commissioning and testing
Once everything is in place, we:
• Fill and pressurise the system
• Test every component
• Balance radiators for even heat distribution
• Set up your heating schedule
• Optimise the system for long term efficiency
We only sign off the installation once we are satisfied that everything is running perfectly.
7. Handover and customer training
At the end of the installation, we provide a complete handover. This includes:
• Showing you how to adjust your heating
• Ensuring you understand your controls
• Answering any questions
• Giving you documentation for future reference
You’ll know exactly how your new system works before we leave your home.
How long does the installation take?
Most air source heat pump installations take 2–4 days, depending on:
• Property size
• Radiator upgrades
• Cylinder changes
• Access and layout
Heat Charge Evolution always works efficiently and respectfully, ensuring your home is left tidy each day.
