MCS Certified • BUS Grant Support • Free Property Survey
Moving to renewable heating is a major long-term decision, and system design is critical. Every Supreme Heating & Air Conditioning air source heat pump project begins with a detailed heat-loss survey. We design systems to perform, not simply to be installed.
Air Source Heat Pump Installers in BROMLEY
Air source heat pumps provide efficient, lower-carbon heating for suitable properties. They can reduce direct emissions, improve energy performance and qualify for government grant support.
Performance depends on correct design. A system installed without accurate heat-loss calculations, radiator assessment and low-flow-temperature planning may be expensive to run and uncomfortable to live with.
Supreme Heating & Air Conditioning is an MCS certified air source heat pump installer serving Bromley, Orpington, Chislehurst, Beckenham and the wider BR postcode area. Every recommendation is based on a detailed property survey.
OUR AIR SOURCE HEAT PUMP RANGE
We install a focused selection of air source heat pump systems. The right option is chosen after a full survey and heat-loss calculation.
A high-quality air source heat pump option for efficient home heating and hot water, specified to match the property’s calculated heat demand.
A compact and efficient air source heat pump range suited to carefully designed home heating and modernisation projects.
A complete heat pump system designed for Octopus smart technology and Cosy Octopus tariff integration.
Why Homeowners Are Making the Switch
A well-designed air source heat pump delivers 3 to 4 units of heat for every unit of electricity used, making it 300–400% efficient under the right conditions.
By replacing gas combustion with renewable heat transfer, an air source heat pump significantly reduces your property's carbon footprint and reliance on fossil fuels.
Heat pump installation typically raises your EPC rating, improving mortgage eligibility, rental compliance and long-term resale value of your property.
The standard BUS grant is £7,500 for qualifying heat pump installations. From 21 July 2026, eligible off-gas-grid homes replacing oil or LPG heating can receive £9,000. We manage the application and apply the grant directly to the installation cost.
A professionally designed heat pump provides an efficient, future-ready heating solution that supports long-term energy planning.
We install Vaillant and Viessmann air source heat pump systems, alongside Octopus Cosy. The recommended system is selected after a detailed survey and heat-loss calculation, then registered with the manufacturer at handover.
Understanding the Technology
An air source heat pump does not generate heat. It moves heat that already exists in the outside air, which is why it can deliver more energy than it consumes.
1
We visit your property to assess the existing heating system, insulation levels and energy requirements. We complete full heat-loss calculations and confirm BUS grant eligibility before recommending a system.
2
You receive a detailed written quotation specifying the recommended system, scope of work, materials, timeline and total cost , before any work is agreed. No verbal estimates, no ambiguity.
3
Our MCS certified engineers install the system in line with UK building regulations and manufacturer requirements. The completed system is tested, commissioned and documented before handover.
4
On completion you receive all compliance certificates, manufacturer warranty registration and a full system handover. We remain available for annual servicing, maintenance and future upgrades.
A heat pump transfers energy rather than creating heat through combustion. That is why accurate system design, correct sizing and appropriate flow temperatures are essential.
Is Your Property Ready?
Suitability is not about the age of your property, it is about its performance. We assess what the data tells us, not what rules of thumb assume.
Many homeowners in Orpington assume their property is too old or too poorly insulated for a heat pump. In our experience, that is often not the case. Properties that have had loft insulation, double glazing, cavity wall insulation or radiator upgrades are frequently suitable, including Victorian and Edwardian terraces across the BR postcode area.
What we cannot determine from a phone call or a bedroom count is whether your specific property will run efficiently. That requires a proper heat loss survey, which is why we carry one out on every job before recommending anything.
Room by Room Heat Loss Calculations
We calculate the actual heat demand of every room in your property. This determines the system size needed and whether any radiators require upgrading to deliver adequate output at lower flow temperatures.
Insulation Assessment
Loft, walls, floors and glazing are assessed. Better insulation reduces heat demand, improves COP and reduces running costs. We advise on any upgrades that would meaningfully improve system performance before installation.
Radiator Sizing Check
Heat pumps operate at lower flow temperatures than many traditional heating systems. We measure every radiator and calculate its output at heat pump temperatures, identifying any upgrades before installation.
Electrical Capacity Check
Air source heat pumps require a suitable electrical supply. We check the consumer unit and available capacity, then include any necessary electrical work in the installation plan.

Exact costs depend on property size, system specification and scope of works. We provide a detailed written quotation following a free survey. No verbal estimates. No surprises.
Running Costs & Long-Term Financial Value
Running costs depend on multiple factors, and a quote that ignores them is not a useful quote. Here is what actually drives your energy bills after installation.
Insulation Assessment
Loft, walls, floors and glazing are assessed. Better insulation reduces heat demand, improves COP and reduces running costs. We advise on any upgrades that would meaningfully improve system performance before installation.

Addressing the Real Questions
We have carried out hundreds of surveys across Orpington and Bromley. These are the questions we hear most often, and the honest answers to each one.
Yes, when correctly sized and installed. Modern systems operate effectively down to −20°C. The issue is not the technology. It is undersized systems running at too high a flow temperature because the design work was not done. That is not a problem with heat pumps. It is a problem with how they were installed.
Modern systems operate at around 40–50 decibels, similar to a quiet conversation or a refrigerator. UK permitted development rules include noise limits for outdoor units. We plan unit positioning as part of every installation to comply with those limits and minimise any impact on your household and neighbours.
Not necessarily. We assess every radiator's output at heat pump flow temperatures. Some properties need no radiator changes. Others need a few upsized. We specify exactly what is required, and the cost, in your written quotation before any work begins. No assumptions. No surprises on the day.
This depends on the property, energy use, system design, electricity tariff and grant eligibility. We discuss the expected costs openly during the survey and provide a detailed written quotation before any commitment.
We install Vaillant and Viessmann air source heat pump systems, alongside Octopus Cosy. The best option is selected using the property's heat-loss calculation, hot-water requirements, available space and energy goals.
Many older properties in Orpington and the surrounding BR postcodes are suitable, particularly those that have been updated with loft insulation, cavity fill, double glazing or improved radiators. The honest answer is that we cannot confirm suitability without a proper survey. What we can tell you is that "older property" alone does not mean unsuitable.
Commercial Properties
We design and install air source heat pump systems for offices, retail premises, educational settings and light commercial buildings across Orpington and the BR postcode area. Commercial installations require detailed load calculations, zone planning and building regulations compliance documentation, not an adaptation of a residential template.
Energy efficiency standards for commercial properties are becoming increasingly stringent. Installing a heat pump system now lowers operational costs, improves your building's EPC and demonstrates alignment with the energy efficiency requirements that are likely to become mandatory for commercial landlords in the years ahead.

Customer Reviews
Genuine feedback from homeowners across Orpington, Bromley and the surrounding BR postcode area.
"The Supreme Heating an Air Conditioning team installed a air-to-water heat pump system approximately three years ago. The level of service is nothing short of amazing from Aleks, Angela and the rest of the team - the installation went smoothly, they were very responsive and communicative, and take pride in their work. For follow up queries and maintenence, the service continues to be excellent, with the team being very responsive in folow up checks, services and explaining the ins and outs of the system. I would recommend the business to anyone looking for any HVAC work without hesitation."

Trustpilot Review
"Supreme Heating installed our heat pump and the results have been excellent. The house is noticeably warmer, and the temperature is now much more consistent across the upper floors. Unlike before, when the boiler left the upstairs far hotter than the rest of the house. Their technical knowledge was clear throughout, and the advice on system size, radiator upgrades and placement options was very helpful. The installation required extra work with pipe routes and paving, but they guided us through it and offered useful support and contacts. Arranging visits worked great, I as I was able call with Aleks directly. Aleks was happy to confirm dates by phone and we kept each other informed about changes by phone as well. Overall, I’m very pleased with the installation and the outcome. I would recommend Supreme Heating for their experience, clear explanations, and a system that’s genuinely improved how our home feels day to day."

Yes, when correctly designed and installed. Modern systems operate effectively down to −20°C and below. The common complaint about heat pumps struggling in cold weather almost always traces back to an undersized system or one designed to run at too high a flow temperature. Our heat loss calculations and design process exist specifically to prevent this.
Not necessarily all of them. As part of our survey, we measure every radiator’s output at heat pump flow temperatures. Some properties require no changes. Others need a handful of radiators upsized. We specify exactly which ones and at what size, with the cost included in your written quotation before any work begins.
A standard installation typically takes two to four days, depending on whether radiator upgrades are required, the complexity of the existing system and any electrical work needed. The full timeline is confirmed in your written quotation before any work starts.
Many properties in Bromley and across the BR postcode area are suitable, including older homes that have had insulation improvements. Suitability depends on insulation levels, radiator sizing, available outdoor space and electrical supply. We carry out a full heat loss assessment before recommending any system. If your property is not suitable, we will tell you clearly and explain exactly why.
The BUS grant is applied as a direct discount on the installation cost. The standard grant is £7,500. From 21 July 2026, eligible off-gas-grid homes replacing oil or LPG heating can qualify for £9,000. We check eligibility, prepare the required documentation and submit the application to Ofgem.
