The UK solar market is entering one of its fastest‑growing periods ever, driven by rising energy prices, strengthened government incentives, and rapid advances in solar and battery technology. For homeowners across Wales and the wider UK, 2026 is an ideal time to invest in Solar PV paired with EcoFlow PowerOcean battery storage — a modern, scalable, and high‑performance home energy system.

This article explains why demand is increasing, how the financial benefits have improved, and why Limegreen’s MCS‑aligned installations make the transition to renewable energy simple, reliable, and cost‑effective.

1. Solar PV Adoption in the UK Is Growing Faster Than Ever

Solar installations across the UK continue to rise at record pace. As of early 2024, the UK had 1,468,652 solar installations, totalling 15.8 GW of capacity, representing a 5.9% increase year‑on‑year.

Several factors are driving this growth:

• Installation costs have fallen by 70% since 2010, making Solar PV much more affordable for homeowners.
• Over one million UK homes now generate their own solar electricity.
• Modern solar hardware is far more efficient, with today’s panels achieving up to 22% conversion efficiency.

With more installations happening each year, confidence and public awareness continue to strengthen.

2. Battery Storage Has Become Essential in 2026 — and More Affordable

Battery storage is now considered a core part of a modern solar energy system. In Great Britain, annual battery revenues for typical 2‑hour systems are forecasted to rise from £96/kW in 2025 to £108/kW in 2026, which improves the financial case for storing excess solar energy rather than exporting it.

At the same time, battery systems have become significantly more affordable due to reduced manufacturing costs, better supply chain efficiency, and increased large‑scale production. While global manufacturing trends don’t directly represent UK retail prices, they do help reduce the installed costs UK homeowners now enjoy.

Pairing Solar PV with EcoFlow PowerOcean provides:

• Reliable storage of surplus solar for evening use
• Reduced reliance on expensive peak‑rate electricity
• Greater energy independence during outages or winter months
• Higher Smart Export Guarantee (SEG) revenues
• A more stable, predictable energy bill every month

3. Strong Government Incentives Make Solar + Storage More Valuable

Government policy continues to make renewable energy financially attractive for homeowners.

Smart Export Guarantee (SEG)

Homeowners receive payments for exporting unused solar electricity back to the grid.

Increased solar subsidies (from 2024 onwards)

Residential solar support increased by 60% in February 2024, lowering the barrier to entry for many households.

Solar’s growing national contribution

Solar now provides 25% of the UK’s renewable energy, with renewables representing 43% of total energy generation nationally.

Combined, these incentives help shorten payback periods and increase long‑term savings.

4. Solar Energy Savings Matter More Than Ever

With energy costs remaining high and unpredictable, UK households are turning to solar to gain long‑term financial stability:

• The average UK residential solar installation costs around £6,500.
• Typical payback periods are now around eight years, significantly faster than a decade ago.
• 65% of UK residents say they would be more likely to buy a home that already has solar installed.
• Rising electricity prices and concerns about future supply continue to push adoption higher.

When paired with EcoFlow PowerOcean, those savings are amplified by reducing reliance on peak‑rate grid electricity.

5. 2026 Technology Improvements Make Solar Systems More Powerful

Technological innovation is accelerating across the solar industry:

• Oxford PV achieved a world‑record 28.6% efficiency using next‑generation perovskite‑on‑silicon solar cells.
• EU‑wide improvements in grid integration and battery‑supported systems continue to enhance performance and reliability.
• Modern systems include VPP‑ready architecture and smarter battery monitoring.
• EcoFlow PowerOcean benefits directly from these improvements, offering:
  • Long‑life LFP battery chemistry
  • Modular expansion options
  • High power output suitable for EV chargers and heat pumps
  • Smart energy management with automatic backup switching

  The result is a stable, future‑proof energy system tailored for modern UK homes.

6. Why Limegreen Installs EcoFlow PowerOcean

Limegreen offers EcoFlow PowerOcean as its primary battery storage solution — chosen for its reliability, safety, and long‑term performance.

Key benefits of EcoFlow PowerOcean:

• Modular LFP battery modules for longevity and safety

What would you do if your boiler breaks down? Who would you call? A heating engineer or a plumber?

We get phone calls all the time from worried customers form across south Wales with faulty boilers who are unsure whether they have called the right person. It’s fair to say that the lines between a heating engineer and a plumber can be blurred and when the pressure is on to stop a leak from a boiler or restore heat to you house, knowing which one to call can make all the difference.

Your boiler uses a lot of water pipes and is plumbed into the mains, so should you call a plumber to repair your boiler? The answer to this question is …. No.

Here’s the difference between the two.

Heating Engineer

The clue is in the name! A heating engineer will work solely on heating in domestic and commercial properties rather than working across the broader industry, making them specialists in heating and gas work. They carry out a wide range of jobs from maintaining and installing heating pipework to fixing appliances when they break down. For this reason, you may prefer to contact a heating engineer rather than a plumber, as they may be more familiar with your issue.

You should still ensure that your heating engineer is Gas Safe registered before allowing them to work on your boiler.

Plumbers

We feel the confusion has come from plumbers, as their trade can cover a multitude of tasks when it comes to bathrooms, kitchens, wet pipes, dry pipes, boiler maintenance or servicing and heating systems.

While many plumbers do possess a number of plumbing skills and qualifications, they are not essential in order for them to trade as a plumber, meaning that anyone can refer to themselves as a plumber without any formal certifications. Although they may be experts in their field and highly recommended, they may not be Gas Safe registered and therefore can not work on your boiler.

Some plumbers are also Gas Safe registered, however this should not be expected as standard. If you find a plumber who is also offering gas central heating services, check the Gas Safe register to make sure that they are legally permitted to work with gas.

Gas Safe Register

A boiler repair or service involves working with gas, so only a Gas Safe registered engineer can legally work on a gas boiler. The gas industry is highly regulated to ensure that relevant services are provided to the highest safety standards, so if your repair is to a boiler or other gas appliance, you must make sure that you contact a Gas Safe engineer.

Luckily Limgreen has everything you need right here, with just one phone call and a few simple questions we can have the right person on the job.

Boiler Check list.

• Check your gas supply – are your other appliances working? Is the emergency control valve open? If none of your appliances are working, then call your gas supplier as it is likely to be a problem at the mains.
• Press your reset button – it might have tripped due to a safety precaution. You should find it on the front of your boiler but otherwise check manufacturer’s instructions. You should NOT have to remove a panel to locate the reset button.
• Is your boiler pilot light? Older models with a pilot light might require reignition. Follow your boiler manufacturer’s instructions. If it’s a newer model, then you could try pressing the deblocking button to reignite the burner.
• Check your power supply – check to see whether one of the fuses hasn’t tripped on your fuse box. Sometimes the obvious is overlooked! And can be fixed with a simple reset.
• Heating controls – check the times on your thermostat / programmer. Get the manual out and make sure you’ve got them set up correctly. Check your timer. Your thermostat will lose accuracy as it gets older and might need replacing.
• Check your boiler pressure – low system pressure in boilers can cause them to run at a lower capacity or cause them to stop working completely. It’s especially common in combi boilers. The pressure gauge should be at 1 bar when your system is cold. If your boiler has a flexible filling top, you’re able to fill up (charge) your system with water yourself. If you’re at all unsure as to how to do this then please call us and we’ll set out one of our Gas Safe Register engineers to service your boiler.
• Radiator valves – these might be a problem. Fiddle around with them to see if you can get them warming up. For a standard lock shield valve, you’ll need to remove the plastic cover and use the appropriate tool (can be from DIY shop) to adjust the setting, whereas a thermostatic valve can just be turned to the desired setting.

Is it worth buying boiler cover to ensure you stay warm whatever the weather?

Boiler cover will give you access to engineers who can repair your heating in an emergency. This usually includes an annual service too, but how do you know the problem isn’t going to come back.

Or on the flip side, do you consider investing in a new boiler?

The first thing to ask yourself is how old is your boiler? If your boiler is old, getting insurance doesn’t really make sense, you will probably struggle to get a policy that is cost-effective and may not even get cover at all. Providers tend to cap the age of boilers they will insure at 15 years, sometimes even lower.

In most instances the average cover would cost around £20 a month which will give you peace of mind, but is this cover worth it?

The answer is No. Most of those who opt for cover will never have to claim, they end up spending more on the cover than getting a brand NEW boiler fitted would cost and a new one means you’re automatically covered by the new warranty or guarantee. Not only will you save on the cost of repairs and insurance with a warranty but modern boilers are far more energy-efficient. Upgrading from a G-rated to an A-rated boiler will save around £340 a year!

What’s more, Limegreen are a Worcester Bosch Accredited installer which means we can offer the full 10 years guarantee on all parts and labour should anything go wrong with your boiler. This is effectively what you get with your boiler insurance, but with the added bonus of having an A-rated energy efficient new boiler, giving you even more savings a year.

The days are getting longer and the traditional deep chill that sweeps the country seems to be lifting. That doesn’t mean it’s plain sailing from here through to Spring. February is the month that we experience more boiler call outs than any other month of the year.

Figures reported by insurer Direct Line for Business state that boiler repair claims during February are 163% higher than the monthly average, with last winter showing a 27% increase in broken down boiler claims compared to the previous year.

Despite having a moderately warm winter our boilers have been under a large amount of stress over the winter period. While we all hunker down and cwtch up in our living rooms and blast the heating first thing in the morning to help the transition from your warm bed to the kitchen, it is easy to get complacent with our boilers. So if you have been lucky enough to have a problem free season so far, it is not uncommon for small problems to start appearing in your heating systems now.

Boiler breakdowns can happen at any time and it is not always the cold weather that causes these problems. Taking the proper precautions can prevent these problems from surfacing and regular maintenance will ensure that your boiler runs smoothly,  so you don’t get caught out with a chilly house next winter.

1 Fill In Those Gaps

Make sure that all your doors are free from drafts and there’s no sneaky cold air vents feeding into your home, you would be …‘blown away’ by the number of draughts that can be found in the average home.

Make sure you put a hat on, loft insulation is the best way to keep the warmth in.  The savings to be made with cavity wall insulation vary greatly dependent upon what kind of house you live in (between £90 and £275), but let’s face it savings are savings no matter how big your wallet is and the warmer your house stays the less you’ll use your heating.

2 Change the temperatures in each room

Not the easiest thing to remember or even do, setting radiators at different temperatures is useful.

Let’s say, like most of us, you’re ‘chilling’ out in the living room in the evening, but you’ll want a bit of heat in the bedroom for when you decide to hit the hay.

You should keep the heating on at a low temperature upstairs because this will save you money on your heating and help you to not freeze in bed.

Also see our Smart thermostats post on ways to heat different rooms.

3 Unplug Electricals

Turn electricals off when not being used or put them on stand by mode.  The amount of appliance wastage we have in our homes now has tripled over the last 15 years.  This again will save you money on your energy bills.

4 Free Up Your Radiators

By this we don’t mean unscrew your rads from the wall so they can make a dash for it when our bad is turned. We simply mean, as we have said many times before – keep stuff away from your radiators.

Ensuring that furniture and clothes horses and other obstructions have been moved will allow heat to circulate more freely around your room.

You wouldn’t try and get a better picture on your TV by moving the cupboard in front of it? Give it room to spread the heat.

5 Get Your Boiler Serviced

Regular servicing not only protects the life of your boiler and keeps it running efficiently, it also protects your family’s safety.

A neglected boiler can be a source of leaks and carbon monoxide poisoning which kills one person in the UK every week and leaves four more seriously ill.

6 Swap To LED Lights

Are you putting Christmas lights up this year?  Well, it wouldn’t be Christmas without lights would it?  However, how much of a strain does this put on your electricity bill the next month?  Alot!  If you switch to LED lights, not only will you be using batteries, you won’t be using your electricity supply.  Another great way to save money during this time of year is take them down when Christmas is over.

The post Save Money This Winter With Our Energy Saving tips first appeared on Limegreen.

There are five common problems that require immediate attention if your home is to stay warm and inviting during the festive season through the New Year, and a well maintained boiler not only keeps you cosy and warm but also money.

No Pilot light. 

This could mean you have a significant problem with your system that requires an expert right away. Pilot lights can go out as a fail safe to prevent an explosion from a build up of gas! If you smell gas you should leave the property and contact us immediately!

My boilers knocking and clunking 

This is an easy symptom to notice as the clunking and clanging is keeping you awake at night! This is probably caused by a build-up of air in the system. Leaking  or loose pipes, taps or connections can draw in air, and the same problem can be caused by low pressure. Not a serious problem but it is something you’ll need to call one of our engineers to resolve.

The lights are on but no one is home?

Everything seems to be working but your radiators are FREEZING! This is the most common fault with boilers and can happen with the new type of ‘condensation boiler’ that has a pipe at the back that funnels condensation away from the unit. Because it’s filled with water it can freeze during winter, causing the whole boiler to stall. This is something you can easily fix yourself  simply by defrosting the pipe with some warm (not boiling!) water. Simply pour it over the length of the pipe until it has thawed.

Working but not warm enough

You may be sat at home with the heating on but it just isn’t pumping out enough heat, what do you do? Well there are a number of causes for this problem,  but perhaps the most common is your thermostat is inaccurate. As a highly sensitive piece of equipment it can only take a slight knock to throw the thermostat out. It needs to be placed with a high degree of accuracy, and over time its delicate electronic components can wear out.  So before calling us to quote you for a new boiler it might be worthwhile checking the thermostat is up full or getting us to check out that old thermostat,  as that might be the main suspect.

The dreaded limescale 

In the same way it can effect your kettle, taps or shower, limescale and hard water are problems that Limegreen residents have had to deal with for years. The white residue from hard water can be visible in most appliance, but can go undetected in your boiler.  If this builds up it can significantly reduce your boilers efficiency and puts stress on the system. If this is the case you need to have it professionally removed using a specialist cleaning product.
