Solar Installers in Kent

Kent's most-recommended network of MCS-accredited solar installers.

Why now

Why solar makes sense in Kent

Kent market notes

Demand in Kent surged after the 0% VAT change in April 2022 and again following the energy price cap rises. Installer lead times in peak months (April-August) commonly stretch to 8-10 weeks — getting on the schedule early is essential if you want commissioning before winter.

Typical property mix

Kent's housing stock is dominated by detached and semi-detached homes (around 60% of properties), with a south-facing or south-east-facing roof on roughly one home in three — ideal for solar. Coastal towns add a higher proportion of bungalows, which are exceptional candidates for full-roof arrays.

Grants, VAT & export

There are no Kent-specific solar grants for homeowners, but the UK-wide 0% VAT rate (in place until at least March 2027), the Smart Export Guarantee (typically 5-15p per kWh exported), and ECO4 funding for eligible lower-income households all apply. Some district councils also offer interest-free renewables loans — we'll flag any that you qualify for during the survey.

Solar panel costs and payback across Kent

The cost of solar panels in Kent in 2026 is driven by three things: the size of the array (kWp), whether you add battery storage, and how complex your roof access is. A typical 4 kWp system on a two-storey semi in Kent lands between £6,500 and £8,500 fully installed, MCS-certified and DNO-notified. Step up to a 6 kWp array with a 10 kWh battery — the fastest-growing spec across Kent — and most homes sit between £11,000 and £14,000. Larger 8-10 kWp systems for detached properties with an EV and a heat pump typically run £14,000-£18,000. Every quote from our vetted Kent installers is at 0% VAT under HMRC's Energy Saving Materials relief, which stays in place until at least March 2027.

Payback in Kent is amongst the fastest in the UK because the region enjoys stronger-than-average irradiance. Solar-only systems typically pay back in 7-9 years; solar plus battery in 8-11 years. Both numbers assume you self-consume 35-50% of what you generate (higher with a battery) and export the balance under the Smart Export Guarantee. Over a 25-year system life, most Kent households will see net savings of £18,000-£32,000 in today's money — closer to £45,000 once inflation on grid tariffs is factored in.

Battery storage and EV charging in Kent

More than three quarters of new solar installs across Kent in 2026 now include battery storage. The reason is simple: Kent homes generate the bulk of their solar during working hours, when nobody is home to use it. A 5-10 kWh battery captures that surplus and discharges it into the evening peak, lifting self-consumption from around 35% to 75-85%. Pair it with a time-of-use import tariff like Octopus Cosy or Intelligent Octopus Go and the battery also charges overnight at 7-9p/kWh, ready to power the morning peak. Popular batteries fitted across Kent include GivEnergy, Fox ESS, Tesla Powerwall 3 and Puredrive — every one carries a 10-year warranty and is IP65-rated for garage or utility-room installation.

A solar-aware EV charger completes the picture. Units like the Myenergi Zappi, Ohme ePod and Hypervolt Home 3 Pro monitor your solar export in real time and divert surplus power into the car — turning miles that would cost 8-10p/kWh on a smart tariff into free solar miles between April and September. Every EV charger installed by our Kent network qualifies for the OZEV EV chargepoint grant where you're eligible (flats and rental properties), and all are notified to your DNO on your behalf.

Roof types, planning and conservation areas in Kent

Kent covers a huge spread of housing stock — from Victorian and Edwardian terraces to 1930s semis, post-war estates, and brand-new developments with integrated in-roof panel options. Most Kent roofs sit between a 30° and 45° pitch, which is close to optimum for a UK south-facing array. East-west splits work well too: they flatten your daily generation curve, which pairs neatly with a battery and EV charger. Concrete tile, clay tile and natural slate all take standard MCS-compliant hook-and-rail mounting; flat roofs (typical of dormers and modern extensions in Kent) use ballasted A-frames that require no roof penetration.

Domestic solar in Kent is generally permitted development, meaning you do not need planning permission — but there are exceptions. Conservation areas, listed buildings, and flats always require consent, and in an Area of Outstanding Natural Beauty the panels must not project more than 200mm from the roof surface. Your installer will check your specific address against the local planning portal before quoting, and any required application (usually decided within 8 weeks) is priced into the quote at no extra cost to you.

DNOs, G98/G99 approval and export tariffs in Kent

Every solar install in Kent needs to be registered with the local Distribution Network Operator (DNO). Most of Kent sits under UK Power Networks or SSEN depending on the postcode, with a small number of fringe areas under National Grid Electricity Distribution. Systems up to 3.68 kW per phase are notified after commissioning under G98; anything larger — which includes almost every 4 kWp+ single-phase install — needs G99 pre-approval, typically decided in 4-8 weeks. Our vetted Kent installers handle every part of that submission, and won't quote you a system size the DNO won't approve.

Once commissioned, your system qualifies for the Smart Export Guarantee (SEG). You do not have to stay with your current import supplier to export — you can shop the SEG market independently. In 2026 the most popular tariffs amongst our Kent customers are Octopus Outgoing Fixed (15p/kWh flat), Octopus Flux (variable, peak export ~26p/kWh, designed for solar + battery households) and E.ON Next Export Exclusive (16.5p/kWh). See our Octopus Flux vs SEG tariff comparison for a full breakdown.

The install process and aftercare on every Kent job

From accepted quote to commissioned system, a standard Kent install runs 4-8 weeks. Your installer books scaffolding, submits the DNO paperwork, and files a Section 80 notification with your council (a free notification, not a planning application). Scaffolding typically goes up the day before install and stays for 5-7 working days. The on-roof work itself takes 1-2 days; battery, inverter commissioning and electrical certification (NICEIC or NAPIT) happen on day two. You'll receive your MCS certificate, Building Control notification (via the Competent Person scheme), electrical installation certificate and full product warranty pack within 5 working days of commissioning.

Every system installed via our Kent network is covered by a 25-year panel performance warranty (typically guaranteeing at least 84-87% output at year 25), a 10-12 year inverter warranty, a 10-year battery warranty, and a 12-year workmanship warranty backed by IWA insurance through RECC — so the workmanship cover survives even in the extremely unlikely event that your matched installer ceased trading. Annual remote monitoring and maintenance is included as standard, and any on-roof repairs during the workmanship period are handled at no cost to you.
