Commercial energy-efficient heating

Talk To Us! MCS Certified

Experts in Renewable Energy

We offer businesses and organisations a variety of low-carbon, energy-efficient solutions to heat (and cool) their buildings. These systems are ideal for social housing, schools, offices, shops, hotels, leisure/sports centres, factories and warehouses, helping save money and reduce carbon emissions. Smart, scalable options can provide a steady, comfortable temperature throughout the year. They can also integrate with other renewable energy sources (eg solar panels).

The two main options we offer for commercial properties are Air Source Heat Pumps (ASHPs) and smart underfloor heating.

Commercial Heat Pumps are an energy-efficient alternative to traditional oil, gas, LPG (‘liquid gas’), and electric heating systems. Air Source Heat Pumps extract heat from the outside air. For every 1kWh of electricity commercial heat pumps can produce up to 3kWh of heat, making them three times more efficient than a standard gas boiler.

Commercial heat pumps can provide reliable heating and hot water all year round, and – properly maintained – will last for 20-25 years. There are a variety of options available, including ductless, ducted and multi-zoned systems, but the right system depends on your property and requirements. So ensure you choose an experienced, qualified installer that can offer advice and guidance.

Smart underfloor heating can be fitted in homes and commercial properties. The systems we use are flexible and easy to install – retrofit/fit-out or new build – without changing how spaces look or function.

There are no radiators or big units to fit and the slim, lightweight panels will fit underneath almost any any type of flooring: tiles, wood, carpet or vinyl. The system is designed to be modular for zoned heating and is suitable for new build, refurb/fit-out or retrofit. The panels heat up to 25% faster than traditional systems and

The underfloor heating system is safe and low-voltage, operating at just 48V DC. It works with renewable energy sources and smart controls, but can also controlled by a standard thermostat, heating up 25% faster than traditional systems. Our smart underfloor heating is another highly efficient, long-lasting and low-maintenance option for organisations.

We will assess your property, energy usage and your carbon emission goals, and recommend the best solution and tariff that meets your requirements. We will also advise whether any Government grants or 0% VAT will apply.

How does it work?

Step 1

Contact us to discuss your requirements – we will discuss your current energy usage, systems, and tariffs, budget, timescales, and any low-carbon goals.

Step 2

We will visit your property to assess its suitability for various options – size, access, age, insulation, number of/proximity to other properties, and your existing systems will all influence our recommendation. We will also advise and assist with any relevant applications for government grant funding or to eg UK Power Networks/National Grid if required.

Step 3

Once a solution has been agreed, we will arrange an installation date and timescale at your convenience. Depending on the system you have chosen, we will advise on any preparation required – typically this is minimal.

Step 4

Once the system has been installed and tested, we will walk you through the controls and give you a thorough handover, along with all warranty documents.

Talk To Us

Great engineers, excellent attitude to the work they carried out and a great knowledge of the products they were fitting. They left my job very clean and tidy and took away all the rubbish, I would be happy to recommend this company if you’re having a car charger fitted. Thanks again to Nick and the two apprentices for a great job. Brian H

FAQs for organisations

What financial support is there available for companies that invest in renewable technologies?

The UK funding landscape has moved away from broad national grant schemes. Most funding is now delivered through a mix of targeted grants, regional programs and private finance.

The National Wealth Fund offers £27.8 billion for transformational UK projects in the form of loans, guarantees and equity for private sector and local government.

Major lenders now offer a suite of green finance products tailored to sustainability projects, from solar and battery storage to wider energy infrastructure, for example Lloyds Clean Growth Financing, Barclays Green Loans and NatWest Green Loans. These are not standard loans, they are designed to reward sustainable investment, often with lower interest rates, reduced fees and incentives linked to environmental performance:

For those looking to reduce upfront costs, the rise of funded delivery models has been a game changer. Power Purchase Agreements (PPAs) allow businesses to install renewable energy without upfront costs, with a third party taking on the investment, installation and maintenance. In return, the business purchases the electricity generated at a fixed, typically discounted rate. The result is immediate savings, reduced exposure to volatile energy prices and a clear pathway to decarbonisation, without tying up capital.

Tax reliefs and capital allowances can also significantly improve green energy project economics. By allowing businesses to offset investment costs against taxable profits, these mechanisms shorten payback periods and enhance returns.

What financial support is available for individuals that want to invest in renewable energy technologies?

At the grant level, opportunities like the Boiler Upgrade scheme can offer up to £7,500 to upgrade gas or oil boilers to more efficient and lower carbon options: Apply for the Boiler Upgrade Scheme: Overview – GOV.UK.

The Warm Homes Plan will offer free upgrades for low income households and cheap loans via banks to other households to install solar PV, batteries, insulation and heat pumps.

Residential customers can also take advantage of 0% interest Green Additional Borrowing Mortgages offered by banks like NatWest to make energy efficiency improvements to homes: Green Mortgages | Energy Efficient Homes | NatWest

Do ESOS and SECR apply to my firm?

ESOS reporting applies to UK companies and UK operations of overseas groups with 250 or more employees or a turnover over £44 million and a balance sheet over £38 million. Firms that fall into this category need to complete energy audits every four years.

SECR applies to UK companies listed on stock exchanges or those which have two of the following: 250 employees or more, a turnover of over £36 million or a balance sheet over £18 million. These firms must add energy, carbon and efficiency disclosures to their annual report, report their greenhouse gas emissions, include an energy intensity metric and describe energy efficiency actions they are taking.
