Why Thatcham Is an Excellent Location
for Solar Panels
Thatcham enjoys some of the highest sunshine levels in the UK. Located in the Kennet Valley in West Berkshire – part of southern England’s sunniest belt – the town benefits from annual sunshine totals well above the national average. Southern England typically receives between 1,600 and 1,750 hours of bright sunshine per year, compared to a UK average of approximately 1,400 hours. That translates into solar irradiance of approximately 1,050-1,150 kWh/m² per year, making Thatcham one of the most favourable locations in the country for solar energy generation.
July is typically the sunniest month, but solar panels do not need blazing sunshine to work; they generate electricity from daylight (irradiance), so they produce meaningful output even on overcast days. With Thatcham’s southern England location and above-average sunshine, solar panels here deliver a strong return on investment and a faster route to energy independence than in many other parts of the country.
Peak solar production in Thatcham runs from April to September, aligning well with longer daylight hours and warmer temperatures. Combined with a well-designed battery storage system, this means you can generate, store, and use your own electricity for a significant portion of the year – dramatically reducing what you pay to the grid.
Thatcham’s Climate Emergency and What It Means for Homeowners
Thatcham Town Council declared a climate emergency on 24 June 2019, unanimously resolving to explore how the council can support a wider programme of activities to help the town become more sustainable, with the ambition of achieving carbon neutrality by 2030. It was one of a number of councils across West Berkshire to take this step.
West Berkshire Council followed shortly after, declaring its own climate emergency on 2 July 2019 and publishing a comprehensive Environment Strategy in 2020. The council set a target of achieving net zero carbon for the district by 2030 – twenty years ahead of the national government target. In 2020, West Berkshire became the first council in the UK to launch a public green investment, which has since won a Public Finance Award and been featured on the inaugural Net Zero 50 list.
The council has invested in solar panels on its own buildings and schools, and the planned Grazeley solar farm – a 75-acre site with 45,000 panels – would generate enough electricity to power approximately 4,400 homes. A local cycling and walking infrastructure plan covering Newbury, Thatcham, Pangbourne, Calcot, and Theale has also been approved as part of the district’s active travel strategy.
For homeowners, installing solar panels is one of the most impactful steps you can take to support Thatcham’s and West Berkshire’s climate goals while also saving money on your electricity bills. Every kilowatt of solar energy your home generates is one less kilowatt drawn from the grid – and one less kilowatt produced from fossil fuels.
How Much Do Solar Panels Cost in Thatcham?
The cost of solar panels depends on several factors, including the system size, your roof’s orientation and condition, the panels and inverter chosen, and whether you include battery storage.
Every property is different, which is why we always recommend a free, no-obligation quote tailored to your specific home and energy usage.
However, to give you a general idea: in 2026, a typical 4 kW residential solar PV system – suitable for most three- or four-bedroom homes – costs approximately £5,500 to £8,000 fully installed. Adding a 5 kWh battery takes the total to approximately £9,000 to £12,000.
Importantly, there is currently 0% VAT on residential solar panel and battery storage installations in the UK. This has been in place since 2022 and has been extended to at least 31 March 2027. This alone saves homeowners a significant amount compared to the standard 20% VAT rate.
We offer flexible finance options, allowing you to spread the cost with affordable monthly payments. Subject to status.
Solar Panel ROI – Why Solar Beats a Savings Account
If you are weighing up whether to invest in solar panels, consider this: how does the return compare with simply putting the same money in a bank?
As of early 2026, the best easy-access savings accounts in the UK pay around 4.5%, with many high-street banks offering just 2-3%. Put £9,000 into a top-paying account at 4.5% and you would earn roughly £405 in interest over the first year – before tax, and before inflation erodes the real value of your money. With the Bank of England base rate at 3.75% and further cuts expected, savings rates are likely to fall further still.
Now consider investing that same £9,000 in a solar panel and battery storage system for your Thatcham home. Based on a south-facing 4.95 kWp installation paired with a 10 kWh battery, a typical household here could expect bill savings of around £1,070 in the first year, plus approximately £144 in Smart Export Guarantee payments for surplus energy sold back to the grid. That is a total first-year gain of roughly £1,214 – an effective return on investment of 13.5%, or around three times the best savings rate on the market.
Unlike bank interest, solar savings are completely tax-free – there is no personal savings allowance to worry about. And while savings rates are expected to fall, your solar returns are underpinned by the electricity you no longer need to buy from the grid. That 13.5% ROI translates into an 88% reduction in household electricity costs from day one, largely because the battery stores surplus daytime generation for evening use – lifting self-consumption from around 35% to over 75%. For Thatcham homeowners planning to stay in their property, the financial case is clear: solar and battery storage comfortably outperforms any savings product currently available in the UK.
Grants and Financial Incentives for Solar Panels in Thatcham
Several financial incentives are available to Thatcham homeowners considering solar panels:
- 0% VAT – residential solar panel and battery storage installations are zero-rated for VAT until at least 31 March 2027. This saves approximately 20% compared to the standard rate.
- Smart Export Guarantee (SEG) – all large energy suppliers are required to offer export tariffs, paying you for surplus electricity you send back to the grid. Your installation must be MCS-certified to be eligible – which all Infinity installations are.
- ECO4 scheme – if you are on a low income or live in an energy-inefficient property (EPC rating E, F, or G), you may be eligible for fully or partly funded solar through the Energy Company Obligation scheme.
- Finance options – we offer affordable finance to spread the cost of your installation. Subject to status.
The Centre for Sustainable Energy also provides free, impartial advice to Berkshire residents on reducing energy bills and accessing available grants. West Berkshire Council has partnered with Lendology, a social enterprise lender, to offer low-cost loans for energy efficiency improvements and renewable energy installations – including solar panels. Lendology loans are offered at a fixed interest rate of 4% (Representative 4.2% APR), with flexible terms and no early repayment charges. This is available to homeowners in the West Berkshire Council area, which includes Thatcham.
The Benefits of Solar Panels in Thatcham
Solar panels generate free electricity from daylight. They produce no carbon emissions, require minimal maintenance, and last for decades. Here are the key benefits of installing solar panels on your Thatcham home:
- Save on electricity bills from day one – generate your own free power and reduce what you buy from the grid.
- 0% VAT – the UK government has cut VAT on residential solar panels and battery storage installations to zero.
- Earn money via the Smart Export Guarantee (SEG) – get paid for surplus electricity you export back to the grid.
- 25-40 year solar panel warranties – the panels we install are built to last, with long-term manufacturer guarantees.
- Increase your home’s value – research from Solar Energy UK confirms that solar is seen as a desirable property upgrade.
- Reduce your carbon footprint – a typical 4 kWp system saves approximately one tonne of CO2 per year.
- Finance available – pay upfront or spread the cost with affordable monthly payments.

Add Battery Storage to Make Even Greater Savings
Most solar panel systems generate surplus electricity during the day – particularly during spring and summer – that would otherwise be exported to the grid. While you do get paid for that electricity via the Smart Export Guarantee, you make far greater savings by using it yourself.
That is where battery storage comes in. A solar battery captures your excess solar energy and stores it for use later in the day – for example, in the evenings or at night – instead of pulling expensive electricity from the grid.
You can also install battery storage without solar panels. This allows you to charge your battery with cheap, off-peak electricity overnight and discharge it during expensive peak hours, reducing your bills significantly.
We install all makes and models in Thatcham, including Tesla Powerwall 3, Sigenergy SigenStor, Fox, SolarEdge, GivEnergy, SolaX, Enphase, Pylontech and more.
Call 0800 909 8882
Battery storage allows you to:
- Store and use more of your solar electricity
- Save even more money every month
- Import less electricity from the grid
- Have emergency backup power in a power cut (certain models)
- Store cheap, off-peak electricity at night and use it during the day
- Become much more energy independent, especially in summer
Planning Permission for Solar Panels in Thatcham
In most cases, solar panels are permitted development and do not require planning permission. This applies to the vast majority of residential properties in Thatcham.
Under permitted development rules, solar panels can be installed on your roof provided they do not protrude more than 200 mm from the roof surface, do not exceed the highest part of the roof (excluding the chimney), and are not installed on a wall facing a highway in a conservation area.
However, there are some important exceptions that Thatcham homeowners should be aware of:
Conservation Areas in Thatcham
Thatcham has a designated conservation area, originally designated in June 1980, which covers the historic core of the town. If your property is in the conservation area, there are additional considerations – but solar is still very much possible.
In December 2023, the government amended permitted development rights to allow solar panels on roof slopes facing a highway in conservation areas and designated landscapes. This was an important change – it means that roof-mounted solar installations are generally permitted in conservation areas, provided they comply with the standard conditions. However, solar panels cannot be installed on a wall facing a highway in a conservation area without planning permission.
Listed Buildings in Thatcham
If your property is a listed building, you will almost certainly need Listed Building Consent before installing solar panels. Thatcham is home to over 50 listed buildings, including the Grade I listed Old Bluecoat School (formerly the Chapel of St Thomas the Martyr, founded in 1304), the Grade II* Church of St Mary, Thatcham House, The Grange, and The Prancing Horse public house. The installation must be reversible and must not alter the building’s character or appearance. We would recommend speaking to West Berkshire Council’s planning department for specific advice on your property.
Our advice: We will assess your specific property and advise on any planning considerations during our initial survey. For detailed guidance, see our comprehensive guide: Do You Need Planning Permission for Solar Panels?
Commercial Solar Panel Installation in Thatcham
Solar panels are not just for homes. We deliver commercial solar projects for businesses, farms, schools, and public sector organisations across Thatcham and Berkshire.
Thatcham is home to a diverse mix of businesses, from the Colthrop Business Park – which includes Thatcham Research, the motor insurers’ automotive research centre – to the town’s retail, distribution, and light industrial sectors. The town’s proximity to Newbury’s business parks and excellent transport links via the A4 and nearby M4 Junction 13 make it a well-connected commercial hub. With electricity costs continuing to rise, businesses across Thatcham and West Berkshire are turning to solar to cut overheads, meet sustainability targets, and future-proof their energy supply.
West Berkshire Council’s climate emergency declaration – with its net zero 2030 target – is also driving increased interest from commercial landlords and organisations wanting to demonstrate their environmental credentials.
Key benefits for Thatcham businesses:
- Dramatically reduce electricity overheads – a well-designed commercial system can cut electricity costs by 50% or more.
- Capital allowances – use the Annual Investment Allowance to offset the cost of your solar installation against taxable profits.
- VAT – commercial installations are subject to 20% VAT, but this is fully reclaimable for VAT-registered businesses.
- Meet sustainability targets and enhance your corporate environmental credentials.

Frequently Asked Questions
How much do solar panels cost in Thatcham?
The cost depends on several factors, including the system size, your roof’s orientation and condition, the panels and inverter chosen, and whether you include battery storage. As a general guide, a typical 4 kW system for a three- or four-bedroom house costs approximately £5,500 to £8,000 fully installed in 2026. Adding a 5 kWh battery takes the total to approximately £9,000 to £12,000. Residential installations currently benefit from 0% VAT. Every property is different, so contact us for a free, no-obligation quote tailored to your specific home.
Do I need planning permission for solar panels in Thatcham?
In most cases, no. Solar panels are typically permitted development and do not require planning permission. However, if your property is a listed building, you will almost certainly need Listed Building Consent – and Thatcham has over 50 listed buildings, so this is worth checking. If you are in Thatcham’s conservation area, solar panels on roof slopes are generally permitted following a December 2023 amendment to permitted development rights, but panels on a wall facing a highway still require permission. We will advise you on all of this during our initial survey.
How many solar panels do I need for a 3-bedroom house?
A typical three-bedroom house in Thatcham would need approximately 8-12 solar panels, depending on the panel wattage, your roof space, and your electricity consumption. This usually equates to a system size of around 3.5 to 4.5 kW. We design every system individually based on your property and usage, so the exact number will be confirmed during our survey and system design process.
Are solar panels worth it in Thatcham?
Yes. Thatcham’s location in southern England, the current 0% VAT on residential installations, and high electricity prices mean solar panels can deliver strong returns for most homeowners. As of early 2026, top easy-access savings accounts pay around 4.5%, but a typical Thatcham solar-and-battery system can generate an effective return of about 13.5% in year one – roughly three times as much – through bill savings and Smart Export Guarantee payments. Unlike bank interest, those savings are tax-free, and your returns are underpinned by electricity you no longer need to buy from the grid. After the system effectively pays for itself, you continue to benefit from free or heavily reduced electricity for the remaining life of the panels, typically 25 years or more.
Can I get a grant for solar panels in Thatcham?
There is currently no blanket government grant for solar panels, but several financial incentives are available. Residential installations benefit from 0% VAT until at least 31 March 2027. The Smart Export Guarantee pays you for surplus electricity you export to the grid. If you are on a low income or live in an energy-inefficient property, you may be eligible for support through the ECO4 scheme. West Berkshire Council has also partnered with Lendology to offer low-cost loans (4% fixed interest rate) for energy efficiency improvements and renewable energy installations – available to homeowners in the Thatcham area. We also offer flexible finance options to help spread the cost.
How long do solar panels last?
Modern solar panels are built to last 25 to 30 years or more. Most manufacturers offer performance warranties of 25 to 40 years, guaranteeing that the panels will still produce at least 80-90% of their original rated output at the end of the warranty period. With proper care, solar panels can continue generating electricity well beyond their warranty period.
Do solar panels work on cloudy days?
Yes. Solar panels generate electricity from daylight (irradiance), not just direct sunshine. While output is highest on bright, sunny days, they still produce meaningful energy on overcast days. Thatcham’s position in southern England – one of the sunniest regions of the UK – means your system will generate more electricity over the year than systems in many other parts of the country.
What is battery storage and do I need it?
Battery storage allows you to store surplus solar electricity generated during the day and use it in the evenings or at night, rather than exporting it to the grid and buying more expensive electricity back later. Adding a battery significantly increases the proportion of solar electricity you use yourself – typically from around 30-50% without a battery to 70-90% with one. You can also charge a battery from the grid using cheap overnight tariffs, even without solar panels. Whether you need a battery depends on your usage patterns, but for most homeowners it is a worthwhile addition that substantially improves the overall return on your solar investment.
What accreditations should a solar installer have?
At a minimum, your solar installer should be MCS-certified. MCS (Microgeneration Certification Scheme) certification is the industry standard in the UK and is a legal requirement for your installation to be eligible for Smart Export Guarantee payments. Look also for RECC membership (consumer protection), NICEIC or NAPIT certification (electrical safety and competence), and TrustMark registration (government-endorsed quality scheme with financial protections). Infinity Energy Services holds all of these accreditations, plus CHAS for health and safety.
How long does solar panel installation take?
Most residential solar panel installations are completed in just 1-2 days. If battery storage is included, this may extend slightly. Commercial installations take longer, typically from a few days to several weeks, depending on the size and complexity of the system. We will confirm the expected timeline during the survey and system design stage.
