MCS Certified • Boiler Upgrade Scheme Approved • Free Property Survey
Upgrading from gas to renewable heating is the right long-term decision for most properties in Orpington, but only when the system is designed correctly. At Supreme Heating & Airconditioning, every air source heat pump installation begins with a full heat loss survey. We design to perform, not to sell.
Air Source Heat Pump Installers in BROMLEY
Air source heat pumps are the fastest-growing renewable heating system in the UK, and for good reason. They reduce carbon emissions, improve energy efficiency, raise EPC ratings and make properties eligible for government grant funding. For the right property, they are a sound long-term investment.
But performance depends entirely on design. A heat pump installed without proper heat loss calculations, correct radiator sizing and low-flow-temperature planning will be expensive to run and frustrating to live with. That is the experience many homeowners have had with poorly installed systems, and it is avoidable.
At Supreme Heating & Airconditioning, we are MCS certified air source heat pump installers based in Petts Wood, Orpington. We have installed heat pump systems across Orpington, Bromley, Chislehurst, Beckenham and the wider BR postcode area. Every installation begins with a thorough property survey, because we design systems to work, not just to be installed.
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.
Eligible homeowners can access the Boiler Upgrade Scheme grant, applied directly as a discount on your installation cost. We manage the full application.
Gas boiler phase-out regulations are tightening. Installing a heat pump now means your property is already compliant, whatever policy changes come next.
All our installations use leading brands including Daikin and Mitsubishi Electric, registered with the manufacturer directly so your warranty is valid from day one.
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 your existing heating system, insulation levels and energy requirements. For heat pump installations we carry out full heat loss calculations and confirm Boiler Upgrade Scheme eligibility.
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 Gas Safe registered and MCS certified engineers install the system in full compliance with UK building regulations and manufacturer specifications. All work is tested and signed off before we leave.
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.
Unlike a gas boiler that burns fuel, a heat pump transfers energy. That distinction is what makes it more efficient, but it also means the system must be correctly designed for your specific property to perform as intended.
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 run at lower flow temperatures than gas boilers. We measure every radiator and calculate its output at heat pump temperatures, so you receive a clear list of which radiators, if any, need to be upsized.
Electrical Capacity Check
Air source heat pumps draw more electrical load than a gas boiler. We confirm your consumer unit and electrical supply can handle the system, and plan any required electrical work as part of the installation scope.

Case by Case
The only reliable way to confirm suitability is a free property survey with full heat loss calculations. If your property is not suitable, we will tell you clearly, and explain why.
The Most Important Factor
Air source heat pump performance depends on correct sizing and flow temperature planning. An oversized system wastes money. An undersized system underperforms in cold weather. The design is what determines whether your heat pump runs at 300% efficiency, or 120%. We get this right every time.
Investment & Running Costs
Transparent pricing is not optional for us, it is how we work. Here is an honest breakdown of what to expect, including the government grant that significantly reduces the upfront cost for eligible homeowners.
Typical Installation Cost Breakdown
Air source heat pump system
£4,000 – £8,000
Installation labour & commissioning
£2,000 – £3,500
Radiator upgrades (if required)
£500 – £1,500
Hot water cylinder (if required)
£500 – £1,200
Electrical work (if required)
£300 – £800
Total before grant
£7,000 – £13,000
Boiler Upgrade Scheme grant
−£7,500 (max)
Typical net cost after grant
From £0–£5,500
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 your property, your energy usage, grant eligibility and long-term plans. We discuss this openly during consultation. For many homeowners in Orpington, the combination of the Boiler Upgrade Scheme grant and an appropriate electricity tariff makes the investment genuinely competitive over a 10–15-year horizon compared to repeated gas boiler replacements.
Yes. Hybrid systems, combining an air source heat pump with a retained gas boiler, are a viable option for certain properties. The heat pump handles the majority of the heating load efficiently, while the gas boiler provides top-up capacity during extreme cold or peak demand. We assess whether a hybrid system is appropriate for your property during the survey.
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.
Side-by-Side Comparison
We recommend solutions based on performance data, not sales pressure. Here is a straightforward comparison of both technologies.
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.

Eligible homeowners can access up to £7,500 from the government, applied directly as a discount on your installation invoice. Final costs depend on property size, insulation, radiator upgrade requirements and the system specified. We provide a full written quotation after a free survey, with no obligation.
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.
