WHY SWITCH TO A HEAT PUMP
Air Source Heat Pumps, What They Do and Why Bromley Homeowners Are Installing Them
A heat pump extracts heat from outside air and delivers it into your home. Instead of burning gas, it moves heat. That distinction matters for efficiency, for running costs and for what your home heating will look like in ten years.
3–4× More Efficient Than Gas
A well-designed heat pump delivers 3 to 4 units of heat energy for every 1 unit of electricity, a COP of 3–4. A gas , even at 92% efficiency, delivers less than 1 unit of useful heat per unit of gas burned.
Lower Carbon Emissions
Heat pumps produce zero direct carbon emissions at point of use. As the UK electricity grid decarbonises, and it is doing so at pace, a heat pump installed today becomes cleaner every year without any changes to the system.
Smart Tariff Integration
Paired with Octopus Energy’s Cosy Octopus tariff, your heat pump runs primarily on cheaper off-peak electricity. This is one of the most meaningful ways to reduce running costs, and it is only available through Octopus Energy smart tariffs.
Full Heating and Hot Water
A properly designed air source heat pump replaces your gas entirely, providing space heating through radiators or underfloor heating, and hot water through a dedicated cylinder. No hybrid required in most well-insulated properties.
BUS Grant Up to £9,000
The Boiler Upgrade Scheme provides a £7,500 grant towards qualifying air-to-water and ground source heat pump installations. From 21 July 2026, the grant increases to £9,000 for eligible off-gas-grid properties replacing an oil or LPG heating system. As an MCS certified, BUS approved Octopus accredited installer, we apply on your behalf and deduct the applicable grant directly from your invoice.
Future-Proofed Heating
UK policy is moving decisively toward low-carbon heating. Gas bans for new-build properties are already in force. Installing a heat pump now, with the grant in place, positions your property ahead of regulatory and market shifts.

THE INSTALLATION PROCESS
How an Octopus Heat Pump Installation Works, From First Call to Final Commission
Every heat pump installation we carry out follows the same disciplined process, because a heat pump that is not designed correctly will underperform for its entire service life. There are no shortcuts that do not cost you later.
1
Initial Assessment
Home Heating Survey & Heat Loss Calculations
Our engineer visits your property and carries out a full heat loss assessment to BS EN 12831, the recognised standard for heating system design. We measure room dimensions, assess insulation levels, check window specifications and evaluate your existing heating distribution system. This survey determines the correct heat pump output for your property. We do not skip this step.
2
System Design
Heat Pump System Design, Radiator Sizing, Flow Temperature & Hot Water
Based on the heat loss survey, we design the complete system, specifying the correct heat pump model and output, calculating required flow temperatures, assessing radiator adequacy and specifying the hot water cylinder. Lower flow temperatures mean higher efficiency. A well-designed system runs at 35–45°C flow temperature, not the 70°C+ typical of gas.
3
Grant & Quotation
BUS Grant Application & Written Quotation
We submit your Boiler Upgrade Scheme application, manage the required documentation and ensure compliance with the scheme rules. Your written quotation shows the total system cost, the applicable grant deduction and the net amount payable. The standard grant is £7,500, rising to £9,000 from 21 July 2026 for eligible off-gas-grid properties replacing oil or LPG heating. There are no additions after the survey unless the agreed scope changes.
4
Installation
Professional Heat Pump Installation
Our engineers install the heat pump outdoor unit, indoor components, hot water cylinder and all associated pipework, controls and electrical connections. Installations typically take two to three days depending on system complexity and whether radiator upgrades are required. We work cleanly and leave the site tidy on completion.
5
Commissioning
System Commissioning, Testing & MCS Certification
The completed installation is fully commissioned, flow temperatures set, controls calibrated, system pressurised and tested under load. MCS certification is issued on satisfactory completion. We walk you through the controls, explain how to operate the system efficiently and provide guidance on Octopus Energy smart tariff integration, including Cosy Octopus, to optimise your running costs from day one.
A heat pump that is correctly designed and commissioned will deliver COP 3–4 consistently. One that is not may deliver COP 1.5–2, barely better than direct electric heating. The survey stage is where that difference is made.
PROPERTY SUITABILITY
Is Your Bromley Property Suitable for an Octopus Heat Pump?
Most Bromley properties are suitable for a heat pump, but suitability depends on specific factors that cannot be assessed without a survey. Here is what we evaluate:
🏠
Insulation Levels
Loft insulation and cavity wall fill have the biggest impact on heat loss. Properties that are not insulated to a reasonable standard will require more heat pump output. We assess this during the survey and advise on improvements where warranted.
📈
Heat Loss Calculations
The heat loss figure for your property, calculated to BS EN 12831, determines the heat pump output required. This is the most important number in system design. We calculate it for every property we survey.
🧱
Radiator System Compatibility
Heat pumps deliver heat at lower flow temperatures than gas. Existing radiators sized for 70°C+ output may need to be upgraded to larger models that work efficiently at 45–55°C heat pump flow temperatures.
⚡
Electrical Supply
Heat pumps require a dedicated electrical supply. Most UK properties have sufficient capacity, but we verify electrical provision during the survey and identify if any upgrades to the consumer unit are needed.
📍
Outdoor Unit Location
The outdoor unit requires space, airflow clearance and a suitable mounting position. We assess the most appropriate location during the site visit, considering noise, aesthetics, planning considerations and manufacturer siting requirements.
WHY CHOOSE SUPREME HEATING
Why Bromley Homeowners Choose Supreme as Their Octopus Heat Pump Installer
Octopus accreditation is the starting point, not the selling point. Here is what sits above it.
Octopus Accreditation, Properly Earned
Octopus accreditation reflects the installation quality, system design and customer service standards expected by Octopus Energy. Our status supports the work we carry out and the service we provide, rather than acting as a stand-alone marketing badge.
Heat Loss Calculations, Every Property, Every Time
We carry out BS EN 12831 heat loss calculations for every property we survey. This is the only way to correctly specify a heat pump. An undersized system will struggle in cold weather. An oversized system will short-cycle and underperform. We get the size right, and we can show you the calculation.
BUS Grant Managed End-to-End
We handle the entire Boiler Upgrade Scheme application, eligibility check, documentation, submission and confirmation. Applications that fail or are delayed are almost always documentation or eligibility issues. Working with an experienced MCS certified installer eliminates most of these risks before submission.
Genuinely Local, 20+ Years in Bromley
We are based in Petts Wood and have installed heating systems across Bromley homes for over 20 years. We understand the local building stock, the typical heat loss characteristics of semi-detached 1930s properties, the insulation challenges of Victorian terraces, the opportunities in new-build estates across the borough.
Written Quotation, Survey First, Always
We do not provide heat pump quotes over the phone. System cost depends on property heat loss, radiator adequacy and installation complexity, none of which can be assessed remotely. We survey first. We quote after. That figure is the invoice. No scope creep, no additions, no surprises.
Cosy Octopus & Smart Tariff Setup
We configure every heat pump installation to work optimally with Octopus Energy smart tariffs from day one, including Cosy Octopus, which provides cheaper off-peak electricity periods specifically for heat pump customers. Running cost optimisation is part of our commissioning process, not an afterthought.

Customer Reviews
What Bromley Homeowners Say About Our Octopus Heat Pump Installations
Verified feedback from homeowners across the Bromley BR postcode area who switched to heat pump heating with Supreme.
"I have used Supreme Heating for over two years now. They first installed my heat pump, then I used them to extend the system to work on different circuits for newly installed underfloor heating and radiators. They also perform annual service and maintenance. Alex and his team are highly professional: everything just works. Any emerging issues (e.g. I had some water leaking from an over-pressure cylinder) are dealt with quickly. The installed system works very well. Importantly - the team are courteous and polite and have always left the premises very clean. They arrive on time and are very responsive to queries (e.g. when I had questions on how to change the configuration of my heat pump to give priority to heating). Alex's quotes are accurate and very competitive, the invoices are comprehensive and clear. Overall: reliable trade company who are easy to deal with."

Air Source Heat Pump
Trustpilot Review
"We recently had a heat pump installed by Aleks and his team, and we are absolutely delighted with the result. The installation was conducted with utmost professionalism, and their attention to detail was impressive. Aleks's expertise really shone through, especially when addressing some minor initial issues, ensuring everything was running smoothly. In addition to the seamless installation, the cost savings have been significant. Thanks to our prior investment in solar and battery technology, and the advantage of cheap overnight electricity rates, this heat pump operates at half the cost of our old gas boiler. This has not only made our home more comfortable and controllable but also more energy-efficient. And best of all, no more gas from Putin! Looking ahead, we anticipate even more benefits, especially with the advent of electric cars supporting Vehicle-to-Home (V2H) technology. This will further integrate our home's energy system, maximizing efficiency and sustainability. The foresight and quality of work by Aleks and his team have positioned us well for these future advancements. We highly recommend their services to anyone considering a heat pump installation. Truly an excellent job!"

Does Octopus Energy offer a special tariff for heat pump owners?
Yes. Octopus Energy’s Cosy Octopus tariff provides cheaper electricity during specific off-peak periods, designed for heat pump customers. Running your heat pump primarily during cheaper tariff windows can significantly reduce heating bills compared to a standard electricity tariff. We configure smart controls integration as part of our commissioning process so you benefit from the Cosy Octopus tariff from day one.
Can a heat pump replace my gas completely?
Yes, when correctly designed and installed, an air source heat pump provides all space heating and hot water previously provided by your gas . The critical factor is correct system design, heat loss calculations, radiator adequacy assessment and correct flow temperature specification. A poorly designed heat pump installation may not replace a satisfactorily. A well-designed one will, and with lower running costs.
Are heat pumps suitable for older Bromley homes?
Many older properties in Bromley are suitable, but suitability depends on insulation levels, heat loss figures and radiator system size. Some older homes require radiator upgrades or insulation improvements before a heat pump will perform efficiently. We carry out a full heating survey – including heat loss calculations to BS EN 12831 – before recommending any system. If your property is not yet suitable, we will tell you and advise on the steps that would make it suitable.
Do heat pumps work in cold UK winters?
Yes. Modern air source heat pumps from Vaillant, Samsung and Daikin maintain effective performance at temperatures as low as −15°C to −25°C outside temperature. The UK climate is significantly milder than Scandinavia and Northern Europe, where heat pumps have been the dominant home heating technology for many years. A correctly sized heat pump performs reliably in UK winter conditions.
