Air Source Heat Pumps for UK Homes
MCS-accredited air source heat pump installation, paired with a fabric-first assessment, full Boiler Upgrade Scheme grant management (£7,500), and optional solar integration. We engineer the whole heating system around your property, not just the unit on the wall.
Air Source Heat Pumps
The Clean Heat
Gas boilers are being phased out. The replacement, when correctly specified and installed, is the air source heat pump. But most ASHP installations underperform because the home was never assessed before the unit went on the wall. Nexura starts differently: with the building.
We carry out a full heat loss calculation before any equipment is specified. If the fabric of the home has issues such as failing insulation, damp walls, or undersized emitters, we address these first. The result is a heat pump that delivers the warmth it was designed to, at the efficiency it was designed for.
When combined with solar and battery storage, your ASHP becomes part of a self-sustaining energy system, generating, storing, and consuming heat at near-zero cost during peak solar hours.

How Nexura Delivers Heat Pumps Differently
Solar-to-Pump Integration
We design your solar and heat pump as a single system. During peak generation hours, surplus solar output is automatically diverted to the heat pump's hot water cylinder, cutting your heating cost to near zero. You're not buying a heater; you're buying a net-zero heating system that generates its own fuel.
Fabric-First Assessment
Every ASHP installation begins with a full heat loss calculation. If your home has failing insulation, damp walls, or thermal bridges, we address the building fabric before the pump goes in. This prevents the most common heat pump complaint of insufficient warmth, ensuring the home can hold heat before we install a system designed to deliver it.
Boiler Upgrade Scheme Management
The UK government's Boiler Upgrade Scheme offers a £7,500 grant toward ASHP installation. Nexura manages the entire process: application, MCS compliance documentation, and voucher redemption. You receive the grant benefit without the administrative burden. Especially valuable for landlords managing multiple properties.
Emitter & Radiator Upgrades
Heat pumps run at lower flow temperatures than gas boilers. Existing radiators sized for 70–80°C will underperform at a heat pump's 35–55°C output. We assess every emitter in the property and upgrade undersized radiators or install underfloor heating circuits where required, one contractor, one install, no coordination between trades.
12-Month Performance Monitoring
Most heat pumps run on default settings that were never optimised for the specific property. Our 12-month monitoring service uses smart thermostats and energy tracking to continuously refine flow temperatures and schedules, lowering bills, extending equipment life, and building an audit trail that supports any future warranty claim.
