Green energy grants for tradespeople in the UK: what is available in 2026

The UK government is spending billions to make homes more energy efficient and reduce carbon emissions. For tradespeople, this translates into real work opportunities. But the market of grants, vouchers, and incentive schemes changes regularly, and it can be hard to keep track of what is available and what it means for your trade.

Here is what is currently available in 2026, who qualifies, and how tradespeople can position themselves to benefit.

Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme offers grants to homeowners in England and Wales to replace fossil fuel heating systems with low-carbon alternatives. The scheme runs until 2028.

Grant amounts:

• £7,500 for an air source heat pump
• £7,500 for a ground source heat pump
• £5,000 for a biomass boiler (in rural properties off the gas grid only)

The grant goes directly to the installer, who deducts it from the customer's bill. So if a heat pump installation costs £12,000 and the customer has a £7,500 BUS grant, they pay £4,500.

What this means for tradespeople

If you are a heating engineer, this is a significant growth area. To install heat pumps under BUS, you need MCS (Microgeneration Certification Scheme) certification. Getting MCS certified takes time and investment, but the demand for qualified installers far outstrips supply.

MCS certification typically costs £1,500 to £3,000 and requires you to demonstrate competence through training and supervised installations. Most training providers offer courses lasting 1 to 2 weeks.

ECO4 (Energy Company Obligation)

ECO4 requires large energy suppliers to fund energy efficiency improvements in low-income and vulnerable households. The scheme runs until March 2026, with ECO+ extending some elements further.

Eligible measures include:

• Loft insulation
• Cavity wall insulation
• Solid wall insulation (internal and external)
• Flat roof insulation
• Room-in-roof insulation
• Heating system replacements
• Solar panels (in some cases)

What this means for tradespeople

Insulation installers, heating engineers, and general builders can all benefit from ECO4 work. You typically work through an ECO4-approved installer or managing agent, who handles the customer eligibility checks and funding applications.

The work is steady and well-paid, though there is paperwork involved. Each job needs to be surveyed, documented, and signed off to PAS 2035 standards.

Great British Insulation Scheme (GBIS)

Launched in 2023 and running through 2026, GBIS targets homes with an EPC rating of D or below in council tax bands A to D. Unlike ECO4, it is not means-tested, so any homeowner in an eligible property can apply.

Covered measures:

• Cavity wall insulation
• Loft insulation
• Flat roof insulation
• Room-in-roof insulation
• Solid wall insulation
• Park home insulation

For tradespeople, GBIS work comes through the same channels as ECO4. Register with approved installers or managing agents in your area.

Home Upgrade Grant (HUG2)

HUG2 provides funding for energy efficiency improvements and low-carbon heating in low-income households living in the worst-performing homes (EPC D, E, F, or G) that are off the gas grid.

Grants of up to £25,000 per property are available for measures including heat pumps, insulation, solar panels, and battery storage.

This is administered by local authorities, so availability varies by area. Check your local council's website for details.

Solar panel incentives

While the Feed-in Tariff closed to new applicants in 2019, homeowners can still benefit from the Smart Export Guarantee (SEG), which pays them for surplus electricity exported to the grid. This keeps demand for solar installations strong.

Solar panel installation is a growing market, with typical domestic installations costing £6,000 to £10,000. You need MCS certification to install solar panels and qualify customers for SEG payments.

How to position your trade business

Get certified

MCS certification is the gateway to most green energy work. Without it, you cannot install heat pumps, solar panels, or battery storage under government schemes. The investment pays back quickly given the volume of work available.

Partner with managing agents

For ECO4 and GBIS work, register with managing agents who coordinate installations in your area. They handle customer acquisition and paperwork while you focus on the installation work.

Upskill in insulation

Insulation work requires less specialist certification than heat pump or solar installation, making it an accessible entry point. Training in cavity wall, loft, and solid wall insulation can open up a steady stream of ECO4 and GBIS work.

Market your green credentials

Homeowners are increasingly looking for tradespeople who understand energy efficiency. Mention your certifications and experience with grant-funded work on your website and Google Business Profile.

Tax implications

Income from green energy installations is taxed like any other trade income. You can claim allowable expenses for training, certification fees, specialist tools, and travel.

If you are investing in MCS certification or training courses, these costs are usually tax-deductible as professional development expenses. Keep all receipts and records.

Use proper invoicing software to track your green energy work separately, which makes it easier to report to managing agents and manage your tax return.

The outlook

The UK has legally committed to net zero by 2050. That means the demand for energy-efficient building work is not going to slow down. Tradespeople who invest in green energy skills now are building a business that will stay relevant for decades.

The grants and schemes will continue to evolve, but the underlying trend is clear: the government will keep funding energy efficiency work, and qualified tradespeople will keep being in demand.

Navigating the Schemes

As a tradesperson, keeping up with the available schemes can be challenging. It is advised to regularly check government websites and trade publications for updates. Joining trade associations can also be beneficial, as they often provide updates and support for navigating these schemes.

It is also worth developing a network with other tradespeople and businesses in your area. Sharing information can help everyone stay informed about new opportunities and requirements. Some local councils also organise workshops and seminars about energy efficiency schemes, which can be a great resource for learning and networking.

Investment in Training

Investing in training is essential to take full advantage of the green energy market. Look for accredited training centres that offer courses relevant to the schemes you're interested in. Many training centres offer flexible learning options, which can be beneficial if you are balancing work and training. Online courses are also available for some certifications, providing greater flexibility.

While the upfront cost of training can be significant, the return on investment is usually quick given the high demand for skilled tradespeople. Additionally, some local councils and trade associations offer subsidies or grants for training in green energy technologies, which can offset some of the costs.

Customer Education

Educating your customers about the benefits of green energy and available grants can also drive more business. Many homeowners are not fully aware of the schemes available to them. By providing this information, you can position yourself as a knowledgeable and trusted advisor, which can lead to more referrals and repeat business.

Consider including information about the benefits of energy-efficient upgrades and available government incentives in your marketing materials. This approach not only educates your customers but also differentiates your services from competitors who may not provide such comprehensive information.

Case Studies and Success Stories

Sharing case studies and success stories of past projects can be a powerful marketing tool. Highlighting the savings and improvements achieved can help potential customers see the tangible benefits of energy efficiency upgrades. Ensure these stories are prominently displayed on your website and social media platforms.

Consider asking satisfied customers for testimonials or to provide a review of your services online. Positive reviews can significantly boost your credibility and attract new business. Incorporating video testimonials can be particularly effective, as they provide a more personal and engaging way to showcase your work.

Final Thoughts

The shift towards green energy is not just a trend, it is a necessary transition that will continue to grow. As a tradesperson, adapting to this change by acquiring the necessary skills and knowledge will not only ensure the sustainability of your business but also contribute positively to the environment.

By staying informed, investing in training, and effectively marketing your green credentials, you can position your business to thrive in the evolving energy market. The opportunities are vast, and those who are proactive will find themselves leading the way in the transition to a greener future.
