Benefits of an ASHP Integration.
Air Source Heat Pumps (ASHPs) are becoming essential for energy-efficient homes, particularly with the phasing out of gas boilers. Whether you are building new, extending, or retrofitting, we help you integrate heat pump systems that work effectively, meet planning requirements, and achieve the energy performance you need.
What's Included
Every ashp integration project includes architect-led design and full technical documentation.
- Heat pump feasibility assessment
- Planning application or Permitted Development confirmation
- Positioning design for optimal performance and minimal impact
- Integration with extension or remodelling designs
- Coordination with M&E consultants and installers
Why work with us?
- Architect-led from day one
- Fixed fees, no surprises
- Planning success rate over 95%
- Direct communication throughout
Why Consider an ASHP?
Air source heat pumps are increasingly attractive:
- Future regulations - Gas boilers will be banned in new builds from 2025; existing homes will follow
- Running costs - With the right setup, ASHPs can be cheaper to run than gas, especially with solar PV
- Carbon reduction - Significantly lower emissions than fossil fuel heating
- Grant support - The Boiler Upgrade Scheme offers £7,500 towards installation
- Cooling option - Many ASHPs can provide cooling in summer
Planning and Permitted Development
ASHPs often qualify as Permitted Development, but conditions apply:
- One unit per property - Only one ASHP is permitted without planning
- Volume limit - Unit must not exceed 0.6m³
- Siting - Cannot be on a wall or roof fronting a highway, must be 1m from boundary
- Noise - Must comply with MCS 020 noise standard
- Conservation/listed - Planning permission required in sensitive areas
We assess your property and advise on the best approach.
Design Integration
Successful ASHP installation requires careful design:
- Positioning - Units need airflow, accessibility for maintenance, and distance from neighbours (noise)
- Screening - Acoustic enclosures or planting can reduce visual and noise impact
- Pipework routes - Flow and return pipes need to reach the house efficiently
- Hot water cylinder - ASHPs need a cylinder (not a combi setup), which needs space inside
- Emitter sizing - Radiators or underfloor heating must be sized for lower flow temperatures
Common Questions
How much does an ASHP installation cost?
A typical domestic ASHP installation costs £10,000-£18,000 before the £7,500 BUS grant. Costs vary based on system size, hot water cylinder, and any radiator upgrades needed.
Will an ASHP work with my existing radiators?
Possibly. ASHPs run at lower temperatures than gas boilers, so radiators may need upsizing by 50-100% to deliver the same heat output. Underfloor heating is ideal for heat pumps.
How noisy are air source heat pumps?
Modern ASHPs operate at 40-50 dB at 1 metre - similar to a fridge. Positioning away from bedroom windows and neighbour boundaries minimises disturbance. Planning conditions may impose noise limits.
Should I install an ASHP when I extend?
Often yes. Extending is a good opportunity to upgrade heating systems. The extension can be designed for underfloor heating, and the disruption of installation is absorbed into the building works.
