Solar Battery Storage in Oxford
Free, written quote after a full survey. Fully insured, MCS-certified installation across Oxford and the surrounding OX postcodes.
Oxford homes generate strong solar yields across the year, yet without a battery most of that energy is exported to the grid for very little return. A solar battery stores what your panels produce during the day so you can use it in the evening, overnight, or whenever your tariff is most expensive. We install Tesla Powerwall 3, GivEnergy, Fox ESS, and EcoFlow systems to match your usage, your roof output, and your budget.
We are based in Redditch and cover Oxford regularly via the M42 and M40. We are MCS-certified for solar installations and NAPIT-registered electricians, which matters here because Oxford's mix of listed buildings, conservation areas, and modern Headington and Cowley estates each brings different installation requirements. We handle the technical detail so you do not have to.
What's included
Every Oxford job includes.
A thorough pre-installation survey of your consumer unit, meter arrangement, and any existing solar setup, so we size the battery correctly and identify any electrical upgrades needed before we start work.
Supply and installation of your chosen battery system, whether Tesla Powerwall 3, GivEnergy, Fox ESS, or EcoFlow, with all cabling, DC isolators, and mounting hardware included in the quoted price.
Full configuration of the battery management system, including tariff-based off-peak charging schedules such as Octopus Go or Agile, so the battery imports cheap-rate electricity as well as storing solar.
Integration with your existing solar inverter or, where you are adding panels at the same time, a full hybrid inverter setup so the whole system is managed from a single point.
A complete test and commissioning run covering charge, discharge, and backup switching, so we leave knowing the system is performing exactly as specified before we sign off.
Handover walkthrough with you covering the monitoring app, how to read your export and import data, and what to do if the system raises an alert, plus all compliance certificates issued on the day.
Local knowledge
Solar Battery Storage in Oxford.
Oxford sits in the Thames Valley and receives solar irradiance broadly in line with the wider South East, making battery storage a sensible upgrade for any home that already has panels or is adding them. The city has a strong cohort of environmentally engaged households, and energy tariffs that reward off-peak charging are increasingly popular here, particularly among the high EV ownership levels in areas like Summertown, Jericho, and the Cowley Road corridor. A well-configured battery with an off-peak tariff schedule can shift a significant proportion of your energy consumption away from peak-rate periods, which is exactly the kind of outcome our installations are designed to deliver.
The building stock in Oxford is unusually varied. The historic centre and inner suburbs contain a dense concentration of Victorian and Edwardian terraces, pre-1900 stonework properties, and buildings within Oxford's numerous conservation areas. Battery storage itself does not typically require planning permission because the unit sits inside the property, usually in a garage, utility room, or airing cupboard. However, if you are combining the battery with a new solar array on a listed building or within a conservation area, permitted development rights may be restricted and listed building consent may be needed. We flag this during the survey so you are not caught out after work has started. Headington, Rose Hill, and Cowley are largely post-war and interwar estates where these constraints are far less likely to apply and installation is generally straightforward.
Cable routing in older Oxford properties deserves careful attention. Solid stone or brick walls, limited loft access in some terraced designs, and older consumer units that may need upgrading before a battery can be safely connected are all common here. Our survey covers every one of these points. Where a consumer unit replacement or additional circuit protection is needed, we quote for it clearly and upfront. There are no surprises on installation day.
Why Oxford
Why Oxford chooses us.
Oxford customers choose us because we bring MCS certification, NAPIT registration, and honest, survey-led quotes to a city where the building stock demands careful electrical work.
We are MCS-certified for solar battery installations, which is a requirement for grid-connection compliance and for unlocking smart export tariffs. Without MCS certification your DNO notification may be rejected and your tariff eligibility affected.
We are NAPIT-registered electricians, meaning every electrical aspect of the installation, from consumer unit work to final circuit testing, is carried out and certified to current BS 7671 wiring regulations with a completion certificate issued on the day.
Every quote is free, written, and itemised after a physical survey. We do not quote blind over the phone or include vague allowances that inflate once we are on site. What the quote says is what you pay.
We carry full public liability and employer's liability insurance, so your property and our engineers are covered throughout the job. You can request evidence of our insurance cover before we start if you wish.
We install across the major battery platforms, Tesla Powerwall 3, GivEnergy, Fox ESS, and EcoFlow, so we recommend what suits your property and usage rather than what we happen to have in the van.
How it works
From enquiry to job done.
- 01Postcode check
Enter your OX postcode on our site or call us on 01527 337155. We confirm that Oxford falls within our coverage area, which it does, and we note any early details about your property type, existing solar, and preferred battery brand to prepare for the survey.
- 02Free survey
We visit the property at a time that suits you. We inspect the consumer unit, meter arrangement, proposed battery location, cable routes, and any existing solar inverter. We take measurements and photos so the quote reflects the actual job, not an estimate.
- 03Written quote issued
We send a fully itemised written quote, usually within 48 hours of the survey. It covers labour, materials, the battery system, any electrical upgrade work identified, and DNO notification. No hidden costs. You can ask questions before accepting.
- 04Installation date booked
Once you accept the quote, we agree a date. We handle the DNO notification for grid-connected battery systems. You receive a confirmation with the engineer's name and an estimated arrival window so you are not waiting around.
- 05Job done, photos sent
We complete the installation, commission the system, and run through the monitoring app with you in person. Before-and-after photos are taken. All compliance certificates, including the NAPIT electrical installation certificate, are issued and sent to you digitally the same day.

Often booked together
Pairs well with.
Most Oxford battery enquiries come from homeowners adding panels at the same time. Installing both together means one scaffold visit, one DNO notification, and a hybrid inverter that manages everything from a single system.
Oxford has one of the highest EV ownership rates in the region. Pairing a battery with a smart EV charger lets you charge your vehicle overnight from stored solar or cheap off-peak grid electricity, cutting running costs further.
Older Oxford properties frequently need consumer unit upgrades before a battery can be safely connected. Combining the battery installation with the electrical upgrade saves a separate visit and keeps certification straightforward.
Worth knowing
Before you book in Oxford.
Oxford has a high proportion of Victorian and Edwardian properties with older consumer units. Before a battery can be connected safely, the consumer unit may need upgrading to a modern split-load board. We assess this at the survey stage and include any required work in your written quote so the full cost is clear before you commit.
If your property or an adjacent structure is listed, or you are in one of Oxford's conservation areas, installing solar panels alongside the battery may require listed building consent or prior approval rather than sitting within permitted development. Battery storage alone, installed internally, is generally unaffected, but we recommend checking with Oxford City Council before proceeding with a combined solar and battery project.
Oxford has a consistently high density of EV drivers, which increases household energy demand substantially. When sizing your battery, account for overnight EV charging as a core load rather than an occasional one. A system sized purely against household consumption without factoring in vehicle charging may underperform in practice. We model this during the survey.
FAQs
Oxford questions.
Do I need planning permission for solar battery storage in Oxford?
For most Oxford properties, no. A battery storage unit installed inside the building, in a garage, utility room, or cupboard, does not require planning permission. It is not an external change and does not fall under permitted development rules in the way solar panels do. The exception is if your property is listed or in a conservation area and you are simultaneously adding new external solar panels. In that case, listed building consent or a prior approval application to Oxford City Council may be needed for the panel element. We assess this at the survey and advise you clearly before any work is committed.
How long does a battery storage installation take in Oxford?
Most residential battery installations take between four and eight hours on the day, depending on the complexity of the cable routes, whether the consumer unit needs upgrading, and the size of the battery system. Properties in older parts of Oxford with solid stone walls or limited loft access can take a little longer because cable routing requires more care. We give you a realistic time estimate at the survey stage so you can plan your day. We do not leave until the system is commissioned, tested, and you have been walked through the monitoring app.
Which battery brands do you install in Oxford?
We install Tesla Powerwall 3, GivEnergy, Fox ESS, and EcoFlow systems. Each has different strengths in terms of usable capacity, backup capability, inverter integration, and monitoring software. We do not have a preferred supplier arrangement that pushes us towards one brand. During the survey we discuss your usage patterns, your existing solar setup if you have one, your EV charging habits, and your priorities around whole-home backup versus simple self-consumption. We then recommend the system that fits those requirements and include the full specification in your written quote.
Can I add a battery to existing solar panels I already have in Oxford?
Yes, and this is one of the most common enquiries we receive from Oxford homeowners. Whether you have a string inverter system or a microinverter setup, there are compatible battery options. In some cases we can AC-couple a battery to your existing inverter with minimal disruption. In others, replacing the inverter with a hybrid model gives you better performance and simpler management. We assess your existing system at the survey, confirm compatibility, and quote for whichever approach works best for your setup. You do not need to replace your panels.
Can the battery charge from the grid overnight as well as from solar?
Yes. All the battery systems we install support off-peak grid charging, and configuring this correctly is part of our commissioning process. Oxford has strong uptake of time-of-use tariffs such as Octopus Go and Agile Octopus, and a battery that charges overnight at lower rates can reduce your bills significantly, especially if you are also charging an EV. We configure the battery management system to your specific tariff schedule before we leave, and we show you how to adjust it if your tariff changes. This is included in the installation, not an optional extra.
Is a battery storage system worthwhile in Oxford if I do not have solar panels yet?
A battery alone, charged purely from the grid overnight, can still reduce your bills on a time-of-use tariff by shifting consumption away from peak rates. However, the strongest case for battery storage is when it works alongside solar panels, storing generation that would otherwise be exported for a small return. Most Oxford customers who enquire about battery-only installations end up adding solar panels at the same time or within a year, because the combined system delivers much better returns. We are happy to quote for battery-only if that suits your situation, and we design the installation so panels can be added later without replacing the battery hardware.
Our commitment
We take a limited number of battery installations each week. That is not a sales line; it reflects how long a properly surveyed, tested, and certified installation actually takes when done to a standard we are comfortable putting our name to. Rushing a battery installation to fit more jobs in is how corners get cut on cable sizing, fuse protection, and commissioning. We would rather do fewer jobs well than fill a diary with work we cannot stand behind.
