About Regal Renewables

Choosing a new heating system is a significant investment. At Regal Renewables, we help homeowners and businesses move to efficient, low-carbon heating without the guesswork. We start by understanding your property, your existing heating system and your requirements so that every install is designed around your property and how you actually use energy, so the system works in the real world, not just on paper.

Our professional assessment includes the information needed to understand your property's heating requirements, including room-by-room heat-loss calculations where required, allowing us to design a system around your home.

Air Source Heat Pumps

A highly efficient, low-carbon alternative to gas or oil boilers. Takes heat from outside air to warm your home and hot water , even in cold weather.

Why people choose ASHPs

  • High Efficiency: They generate 3 to 4 times the amount of heat energy they consume in electricity.
  • Reliability in the UK: Modern systems are specifically designed to work in temperatures as low as -25°C, making them perfect for UK winters.
  • Boiler Upgrade Scheme (BUS): Provides £7,500 upfront for homeowners in England and Wales to replace fossil fuel systems.

Ground Source Heat Pumps

A low-carbon heating system that draws stored heat from the ground beneath your property to warm your home and hot water, whatever the weather above.

Why people choose ground source heat pumps

  • High Energy Efficiency: They achieve 300% to 400% efficiency, producing 3 to 4 units of heat for every 1 unit of electricity they consume.
  • Year-Round Consistency: Unlike outside air temperatures that fluctuate wildly in winter, underground temperatures remain stable (typically 8°C to 13°C), ensuring optimal performance during the coldest months.
  • Lower Energy Bills: Because they extract free natural heat from the earth, switching from traditional or older systems can significantly reduce your annual heating costs.
  • Reduced Carbon Emissions: They rely largely on renewable geothermal energy, cutting household CO2 output compared to gas, oil, or direct electric heating.

A straightforward path to a better system.

  1. 01

    Start with a free consultation

    Tell us about your property and what you're looking to achieve.

    Get in touch and tell us about your project. Tell us about your property, the existing heating system, requirements and what you're looking to achieve so that we can understand whether Regal Renewables is the right fit for your project. We will then be in touch with next steps. No obligation and no charge.

  2. 02

    Assessment, design & tailored proposal

    We assess your property before recommending your system.

    We'll carry out a professional Renewable Heating Assessment, including the information needed for room-by-room heat-loss calculations, system sizing and installation planning. We'll then provide you with a tailored proposal based on your property and requirements.

    Assessment: from £199, fully credited against your installation if you proceed with us.

  3. 03

    Installation & handover

    We install, commission and hand over your new system.

    Once you're happy with the proposal, we'll agree the installation arrangements, install your system and commission everything properly. We'll then walk you through your new heating system so you know how to use it confidently.

  4. 04

    Aftercare & support

    We're here beyond installation.

Professional assessment

Your Home. Your Heating. Properly Assessed.

Professional Renewable Heating Assessment, starting from £199

Every home is different, which is why we don't believe in recommending a heating system based on a quick conversation or a generic estimate. At Regal Renewables, we take the time to understand your property, your existing heating system and what you want to achieve before recommending a renewable heating solution.

What's included?

A thorough assessment covers the details that actually shape the right system for your home:

  • Your property's existing heating system
  • Your heating and hot-water requirements
  • Existing radiators and/or underfloor heating
  • Potential air or ground source heat pump options
  • Suitable locations for equipment
  • Hot-water cylinder requirements
  • Room-by-room heat-loss calculations
  • Sunamp Thermino integration where appropriate
  • Pipework and installation routes
  • Electrical and practical installation considerations
  • Access requirements
  • Any other relevant factors

Your £199* isn't lost if you choose us

If you decide to go ahead with your installation, the full assessment fee is deducted from your final installation price. It isn't an extra cost, it simply becomes part of your project.

Why do we charge for the assessment?

An assessment lets us properly understand your property before we recommend anything. That means a more informed, individual quotation built around your home, rather than a rough estimate from a quick conversation.

Not ready to book an assessment?

That's no problem at all. Start with a free initial consultation instead, and we'll talk through your options and whether an assessment is the right next step for you.
