Air Source Heat Pump Installers
Considering replacing an oil or gas boiler, or planning lower-carbon heating for an older home? We assess the property, size the air source heat pump correctly and explain the installation. Call Alderminster to arrange a survey.
The practical benefits of a correctly installed heat pump
An air source heat pump works best when the heating system suits lower flow temperatures. That can mean reviewing radiators, pipework, controls and insulation alongside the outdoor unit, rather than treating the pump as a like-for-like boiler swap.
We identify changes that matter for comfort and running costs, then set out the work and quotation clearly before installation begins. You can decide with a complete picture of the property, disruption and likely electricity use.
Suitable for older homes
Older, solid-wall or off-gas-grid properties need careful planning, so we assess the existing heating system before recommending a heat pump.
Heating matched to the property
The right heat pump size depends on the rooms, insulation and heat loss, so we calculate the requirement rather than rely on the boiler size.
Controls that work with the system
Lower-temperature heating needs different control settings, so we configure the system to deliver steady warmth without constant manual adjustment.
Electrical work included
A heat pump adds electrical demand, so our in-house electricians can assess the supply and complete related electrical work alongside the installation.
A clear installation plan
You see the proposed equipment, property changes, disruption and quotation before work starts, so the decision does not depend on guesswork.
Grant-ready installation
MCS certification means we can make a Boiler Upgrade Scheme grant application on your behalf where the property and installation meet the requirements.
Qualified renewable installers
Your heat pump is installed by MCS-certified engineers, giving you the certification needed for an eligible renewable heating installation.
Air Source Heat Pump Installation: Your Questions Answered
Can an air source heat pump work with my existing radiators?
If access is limited, we agree equipment position, access needs and electrical changes. Clear the installation route and tell us about planning restrictions or asbestos concerns, so we can plan safely.
How long does air source heat pump installation take?
Installation time depends on the property, access and any radiator, pipework or electrical changes. After surveying, we explain the sequence clearly, including preparation, outdoor unit fitting, commissioning and handover.
Will an air source heat pump work in an older home?
Older homes can work well with a heat pump. We assess heat loss, fabric, outdoor-unit position and electrical capacity, then identify practical changes before recommending equipment for the individual home.
How disruptive is air source heat pump installation?
Most disruption comes from changing pipework, radiators or electrics, rather than fitting the outdoor unit. We protect floors, agree isolation points beforehand and leave rooms clean after commissioning is complete.
What maintenance does an air source heat pump need?
Maintenance is straightforward: we check filters, sensors, outdoor-unit airflow, electrical connections and system pressure, then test operation. Keep leaves clear throughout and report unusual noise, smells or performance changes promptly.
MCS-certified installers with long-standing engineering experience

Clear advice and careful heat pump installation
An older property can make cable routes, condensate and outdoor-unit placement less straightforward. We work through those details before equipment arrives, including access, wall penetrations and protection for surfaces. That reduces changes during the installation.
On installation day, the heating and electrical work is coordinated by our team. We protect floors and access routes, keep you informed if a detail changes, and test the system under operating conditions before leaving. Any making-good is completed neatly.
Once the system is running, questions do not disappear with the tools. We retain the installation information, so the engineer supporting a later fault or adjustment can start with the details. We support heat pump customers across Warwickshire, Oxfordshire, Gloucestershire and the North Cotswolds.
