Home Energy Scotland funding

No solar grant in Scotland, and you do not need one

Panels and batteries carry 0% VAT until 31 March 2027, and the Smart Export Guarantee pays you for what you send back. We size the array to your own usage first, so the savings come from the design, not a subsidy.

The problem

Solar Panel Installation in Glenrothes: Unsure Your Roof Can Pay Its Way?

“I don’t think solar panels work well in our cloudy weather.”

“Can I really get my money back with solar?”

“Our roof is flat. Can we still have solar panels?”

Those worries are fair, and the answers depend on your roof more than the weather. Pitch, shading and the power you use by day set the payback on solar panel installation in Glenrothes, and 0% VAT on panels and batteries runs until 31 March 2027.

We read your electricity use and map any shade before fixing a panel count, as our guide on how many solar panels you need in Scotland explains.

Glenrothes has flat and mono-pitch roofs beside pitched ones. Flat roofs take angled frames within 1 metre of the roof, and on Collydean’s staggered terraces a taller neighbour can shade the low end of yours.

The solution

Solar panel installation in Glenrothes on flat and pitched roofs

A flat roof takes panels on angled frames kept within a metre of the roof, and a mono-pitch or slate roof gets its own fixing method. We read your electricity use and map the shade before settling the panel count.

Roof covering checked

On a flat roof we check the covering and deck before any frame goes on.

Neighbour shade measured

On staggered terraces a taller neighbour can shade the low end of your roof, and we map it.

Heat pump in the design

If you plan a heat pump as well, one design sizes the panels and battery for its winter load.

Battery on your tariff

Before we leave, the battery follows your tariff’s cheap and expensive hours.

The Scottish solar question · answered in data

It works here. Here is a year of proof.

Scroll through the year: real generation from a 10.5 kWp array on a Scottish roof, winter trough included.

00 · The light question

Panels do not care how warm it is, only how bright. So the only honest answer is a year of output.

01 · The winter trough

December makes a tenth of June. We plot it, because you will notice it on your first winter bill.

02 · Above the line

From March to September the array makes more than a typical home uses. The spare either exports for income or charges a battery.

03 · The long days

Northern summers pay the winter back: June alone can cover two months of an average home’s use.

04 · The yearly truth

Around 9,000 kWh a year from one Scottish roof. Not a lab figure, a metered one.

Real Homes, Real Results.

From £600 a Month to £24.79: Christine’s Solar, Battery and Heat Pump Fix in Gartcosh. Christine’s home in Gartcosh, Glasgow already had an air source heat pump, never set up correctly, and some months the bill averaged around £600.

We installed a 10.5 kWp black bifacial solar PV array with 20.8 kWh of battery storage and corrected the heat pump’s flow temperatures, balancing and controls. The monthly bill dropped to £24.79, an annual saving of around £6,900.

Solar and the battery now cover 100% of the family’s daily electricity in most months. A Glenrothes or Kirkcaldy survey starts in the same place, and our heat pump and solar package covers the combined design.

“Excellent service before & after installation. We are also grateful for his knowledge and input into adjusting our heat pump and currently our bills are massively reduced.” Christine C, Gartcosh, ★★★★★

01
YOU ARE HERE · BOOK IT NOW

Step 1: Free Engineer-Led Survey & Quote

We measure the roof, note its pitch and direction, check shading from neighbouring roofs and trees, and look at the consumer unit and space for an inverter and battery.

On a flat roof that includes the covering and deck; in Kirkcaldy’s conservation area, the planning position. Your quote sets out yearly generation, the share you use at home, export income and payback.

02

Step 2: Fast & Expert Installation

Scaffolding goes up first. Then the team mounts the panels, wires in the inverter and battery, tests and commissions the system and completes the MCS registration. The survey gives you the installation dates.

03

Step 3: Enjoy Lower Bills & Comfort

Before we leave, the monitoring app is on your phone and the battery follows your tariff’s cheap and expensive hours. We help with the export tariff application too.

Costs & savings

Solar Panel Cost, Grants and Savings in Glenrothes and Kirkcaldy

Three price points cover the solar PV systems we quote across Mid Fife:

•  From around £8,000 for panels only.

•  Around £11,000 for a typical solar and battery quote.

•  Up to around £19,000 for a larger array with substantial battery storage.

Angled frames on a flat roof and extra scaffolding on a long terrace move a figure up the range. VAT on panels and batteries stays at 0% until 31 March 2027.

Home Energy Scotland has no solar PV grant and has closed its solar PV and battery loan, as our guide to solar panel funding in Scotland records, so savings come from:

•  Each unit you use at home, worth the full price your supplier charges.

•  Each unit you export, paid 12p on Outgoing Octopus as of September 2026.

•  A battery lifting self-use from 35-40% to 70-80%; a solar and battery system pays back in 8 to 12 years.

Compare the export rates in our Smart Export Guarantee guide.

Yes. On a flat roof in Glenrothes we mount the panels on angled frames within the 1 metre limit of Scotland’s permitted development rules, spaced so the rows don’t shade each other in winter. The survey checks the covering and deck first, since a worn roof is better re-covered before panels go on.

Solar panel cost in Glenrothes runs to around £11,000 for a typical solar and battery system, from around £8,000 for panels alone and up to around £19,000 for a large array with a big battery. Every option carries 0% VAT until 31 March 2027, and a flat-roof frame system costs more than a pitched-roof fit.

Yes. We install solar panels in Kirkcaldy and Dysart as well as Glenrothes, Leslie and Markinch. On sandstone houses in the Abbotshall and Central Kirkcaldy Conservation Area the array goes on the rear pitch in most cases, and our guide to fitting solar to older and listed Scottish properties covers consent. On slate roofs we fit hooks beneath the slates.

Home Energy Scotland offers no solar PV grant to Glenrothes households, and it stopped accepting new applications for its solar PV and battery loan. Your savings come from the 0% VAT rate, from buying less electricity and from export payments under the Smart Export Guarantee.

It depends on the pitch. A steep north-facing mono-pitch roof in Glenrothes loses a large share of what it would make facing south, and payback stretches too far. A shallow one loses much less. If a garage, extension or flat section faces better, we look at that instead.

In most Glenrothes houses, yes, and more so with a heat pump. The battery holds the afternoon surplus for the evening peak and fills from a cheap overnight rate in winter. Our solar battery storage page shows the EcoFlow and Fox ESS systems we fit.

Yes, though solar energy in Glenrothes runs far lower in December than in June, and on a mono-pitch or flat roof the tilt we choose sets how much low winter sun it catches. Our guide to solar panels in a Scottish winter explains the seasonal pattern.

Aventus installed an ASHP heating system for us in a 1950s house in Newton Mearns. Initially we contacted them to help us future proof our home as we were planning some retrofit works. They carried out the preparatory pipework during the build & were very good at working around our timeline and liaising with the builders. Following this we decided to see it through and had the new heat pump installed towards the end of the building works. During the installation, the team were all very polite and helpful. We had the majority of pipework replaced with copper alongside 4 new radiators & a cylinder installation which was all carried out to a high standard. The team were patient with our specific requests. We are delighted with the dark grey Panasonic unit & appreciated the fact the unit is not over specified which means that it sits neatly underneath our new windows. There were various post install issues however these were resolved with a professional attitude. So far we have found the house to be very cosy with exceptionally hot water which exceeds our expectations. Time will tell over the winter how efficient it is given the age of the house, however we feel reassured having Aventus by our side and would not hesitate to recommend them to others.

We wanted to retrofit our home to improve energy efficiency, change to an air source heat pump (ASHP) and add solar panels and a battery. Aventus Eco was recommended by a Retrofit Consultancy. Sean clearly explained and planned out the processes for our ASHP. We really felt that he was interested to make it work well for us. Installation was smooth. The team was well coordinated and communicated well during the process. They completed the work to a very high standard and minimised any disruption to our home. We were so impressed with the ASHP fitting that we quickly followed this up with Aventus Eco planning and installing our solar panels and battery. We would highly recommend Sean and the Aventus Eco team.

Changing from gas central heating to renewables isn’t simple but, having asked four companies to quote to convert our system, Sean stood out as someone who cared about getting the design right, optimising it for our house while clearly explaining how and why. He helped us understand how heat pumps, solar panels and batteries all work together and gave us confidence that the conversion would be possible and relatively simple. The Anvetus installation team were brilliant - polite and efficient with a can-do attitude to problem solving. They cared about our property, checking in with us as they worked and clearing up as much as possible each day. Everything felt planned and coordinated and a heat pump, new hot water tank and system, 10 solar panels and a battery were installed and up and running in a week, despite some unexpected challenges along the way. The whole team went out of their way to make this a smooth experience, from initial visit to final handover paperwork. We would highly recommend Sean and Aventus Eco.

Our household was going through the Home Energy Scotland grant and loan scheme as we qualified for a heat pump. Sean came recommended by an insulation company and I’m glad that I reached out. Despite being very busy, Sean was keen to get a solution for us, his knowledge and work ethic came across immediately so we were happy to have Aventus take on the work. Meeting, survey, work scheduled, and completed to a very high standard. We’re very happy with our heat pump system as well as the ongoing support from Sean.

Sean and the team at Aventus Eco did a fantastic job installing our air source heat pump. They were really friendly, proactive and efficient throughout the whole process. After trying to find a suitable air source heat pump installer for a number of years, Sean filled us with confidence from the moment we met him. He was the first person who properly reassured us about the design, the suitability of the system and the long-term cost benefits. The installation itself was carried out with real care and professionalism. The team put everything back in place afterwards and left the house as though they had never been there. Since the instal, the house now constantly feels like it is at a comfortable temperature, and the amount of energy we use on a daily basis compared to our old electric boiler has been reduced. We are looking forward to seeing how this continues in the colder months. We would happily recommend Aventus Eco and Sean to anyone considering an air source heat pump.

Sean and the team at Aventus Eco provided exceptional support when we needed it most. Our heat pump had been incorrectly installed by another company that has since gone into liquidation, leaving us with nearly three years of no heating, ongoing faults, and constant leaks. Aventus Eco truly saved the day. Sean quickly identified the issues that had caused continuous problems for years and resolved them properly. We finally have warmth in our home again, along with peace of mind and renewed hope. The service has been first class throughout, with excellent ongoing support. I cannot recommend Sean and Aventus Eco highly enough and would like to thank them for their professionalism, expertise, and commitment to doing things right.

Outstanding Service from Aventus Eco Ltd – Highly Recommended! I had been struggling with unusually high electricity consumption—around 50 kWh per day—due to my air source heat pump system. Despite reaching out to multiple companies, including the original installer, no one was willing to help or even respond. That’s when I contacted Sean from Aventus Eco Ltd, and I’m so glad I did. Sean promptly visited my home, conducted a thorough evaluation of all relevant factors, and successfully identified the root cause of the issue. He didn’t stop there—he also provided a detailed report that I could share with the installer and even offered to assist further in resolving the problem. Sean’s professionalism, technical expertise, and willingness to go the extra mile truly set him apart. He is an absolute superstar, and I can’t recommend Aventus Eco Ltd highly enough for anyone facing similar challenges.

Exactly as the process should be – right from start to finish Aventus Eco fitted solar panels, battery storage and an air-source heat pump, and the whole experience has been great. There was no hard sell from these guys, just lots of advice from people who clearly care about what they do, their business and their reputation. They took the time to get the design right for my home, including properly working out our power use and heat loss and sizing everything accordingly. The solar panels were a no brainer, but Aventus suggested right sizing the solar panels and adding battery storage. Home energy when the sun’s not shining – brilliant. It’s working flawlessly. The heat pump means I’m no longer dependent on global oil and I’ve cut my carbon footprint. Heat pumps get a lot of bad press, often due to hard-sell companies pushing numbers rather than doing the job properly. The difference here is the care Aventus put in, and the work they have done with Heat Geek and their accreditation process (check their Youtube videos). That was the deciding factor. None of the other companies I spoke to had it. It gave me real confidence everything would be set up properly — and it shows. Originally, I wanted to keep the oil boiler “just in case”. I’m glad I took the leap to ditch it and trust the Aventus design. The house is comfortable and warm throughout. Neat install, great communication, and they made the grant process easy. Aventus Eco combine technical know-how with genuine customer care, and I’d happily recommend them. Thanks. Genuinely.

Outstanding service, difficult decision to make to change to air source heat pump especially give the level of misinformation. Sean/Aventus Eco were outstanding in helping me explore and decide that this was right solution. Additionally it involved full house re-plumb because of problems with the old system, This was handled sensitively and professionally by all the members of the team with Sean setting very high expectations for everyone. I had hesitated because of the level of disruption but in fact it all went very smoothly. Thank you Sean/Aventis Eco and your team. I have no hesitation in fully recommending Sean and Aventus Eco Ltd.

Aventus Eco installed solar panels and a battery and all went like clockwork. Now running virtually all day on a few £ of off peak electricity (Octopus) and the rest is solar feeding into the battery. Very pleased with the result and the thorough job done by Aventus Eco.

After having several companies provide quotes for solar panels for my husband and me, Aventus ECO was by far the best. Their team was professional, transparent, and most importantly, there was no high-pressure sales pitch at all!

We initially had Sean over to provide a quote, and as we didn’t know much about heat pumps, he explained everything clearly and in a way we could easily understand. He emphasized the importance of proper heat loss calculations for our property, which helped us determine which existing radiators we could keep. Sean also walked us through how the system would operate once installed and shared tips on how to get the best efficiency from it. When the team came to install the system, the entire process was incredibly streamlined and completed in just three days. The guys made sure to cover all our carpets and left the place spotless. I can honestly say Sean and his team were fantastic—our heat pump is now up and running, and even on the coldest days, our energy usage is nearly half compared to gas. Although we’ve needed to tweak a few settings, Sean took the time to show us exactly how to adjust everything. I would highly recommend him and his team to anyone. In fact, we’ve already referred him to our neighbors, and he’s now working on their system too. Thanks again, Sean and team

We had an excellent experience with Sean and his team at Aventus Eco. They recently installed our air source heat pump and hot water system, and Sean was hands-on throughout the entire process. What really stood out was the additional guidance Sean provided about how we could improve our home’s insulation and reduce drafts. He explained how making these simple DIY improvements would help lower the heat loss in our home, ultimately reducing our energy bills in the long run. Sean’s approach was practical and cost-conscious, giving us great tips for upgrades that we could do ourselves to make the system even more efficient. The level of detail and care he put into both the installation and the advice was impressive. It’s clear that Aventus Eco is dedicated to not just installing systems, but making sure they perform at their best for the customer. We couldn’t be happier with the outcome and would definitely recommend Aventus Eco to anyone looking for a reliable, knowledgeable, and customer-focused company.

Aventus Eco is hands down the best company I’ve worked with in a long time. From the first phone call, I knew I was in good hands. Sean took the time to understand my needs and walked me through the entire process, from initial consultation to installation day. What really stood out to me was how well they communicated — I always knew what was happening and when. There were no surprises, and the installation was done ahead of schedule! The heat pump has been running flawlessly, and I’ve already noticed a drop in my energy bills. I highly recommend Sean and his team for their professionalism and efficiency!

I recently had an air source heat pump installed by Aventus Eco, and I couldn’t be happier with the experience. Sean was my main point of contact, and he was fantastic. He walked me through the entire process from start to finish, explaining everything clearly and making sure I understood what to expect. On the day of the installation, the team showed up on time and got straight to work. They were professional and efficient, and the whole installation went smoothly. They took the time to ensure everything was set up correctly and even cleaned up after themselves, leaving no mess behind. The heat pump itself is working great, and I’ve already noticed a difference in my home’s comfort and energy efficiency. Overall, I’m really pleased with the service from Aventus Eco and would definitely recommend them to others. Thanks again to Sean and the whole team!
