More UK homeowners than ever are asking the same question: rather than waiting for energy bills to come down, what can I actually install at home to generate my own power?
It's a good question — and the answer is more accessible than most people expect. Several technologies can help your home generate clean energy, cut bills, and reduce its environmental footprint. But they don't all suit every property, and they work best when you understand what each one does — and where its limits are — before choosing where to start.
This guide covers all the main types of renewable energy available for UK homes: what each one does, which properties it suits, what you should watch out for, and what you need to know before making a decision. If you want to understand full costs and returns for each upgrade, our separate guide to home energy-efficient improvements covers that in detail.
What Counts as Renewable Energy for a Home?
Renewable energy comes from natural sources that replenish themselves — sunlight, wind, heat from the ground — rather than from fossil fuels like gas or coal that are finite and polluting. For homeowners, it means generating some or all of your own energy on site, reducing what you buy from the grid. For a full explanation of what renewable energy actually means and how it differs from fossil fuels, see our dedicated guide.
What Are the Main Types of Renewable Energy Available for UK Homes?
There are seven main types of renewable energy that UK homeowners can install: solar PV panels (electricity from daylight), solar thermal panels (hot water from sunlight), solar battery storage (stores surplus solar for later use), heat pumps (heating and hot water from ambient air or ground heat), biomass boilers (heat from organic fuel), small-scale wind turbines (electricity from wind), and micro-hydro systems (electricity from flowing water).
For most UK homeowners, solar panels and heat pumps are the most practical and accessible starting points — they suit a wide range of properties and have well-established installation routes. Solar thermal is a smart, lower-cost option for homes with high hot water demand. Biomass, wind, and micro-hydro have specific requirements that make them suitable for a smaller number of properties — mainly rural or large-site homes.
Later in this guide, we also cover emerging technologies — including plug-in balcony solar and next-generation heat pumps — that are likely to become mainstream options over the next few years.
Solar PV Panels
Solar PV (photovoltaic) panels convert daylight into electricity that your home uses directly. Any surplus is either stored in a battery or exported to the grid — and you can get paid for that export through the Smart Export Guarantee (SEG).
Best suited to: Homes with a roof that faces south, south-west, or south-east with minimal shading. East/west-facing roofs can still generate useful amounts, though output will be lower.
When it may not make sense: If your roof is heavily shaded by trees, neighbouring buildings, or chimneys, solar output can be significantly reduced. In those cases, a heat pump or solar thermal may be a better first step. Solar is also less suitable for listed buildings or properties in conservation areas, where planning restrictions may apply.
What you give up: Solar panels generate electricity only when there's daylight. Without a battery, you'll still buy grid electricity in the evenings. Output also drops in winter and on overcast days — though panels do still generate, just less. Over time, panels degrade slightly (typically around 0.5% per year), and inverters usually need replacing after 10–15 years at additional cost.
Switch Together organises group solar installations through local councils — giving you access to vetted installers and group pricing that's hard to match going it alone. For everything you need to know, see our full solar panels guide.
Solar Thermal Panels
Solar thermal panels look similar to solar PV panels, but they do something quite different. Instead of generating electricity, they capture heat from sunlight and use it to warm water — typically covering a significant share of a household's annual hot water needs, particularly in summer.
It's an important distinction: if your goal is to cut electricity bills, solar PV is the right choice. Solar thermal is specifically a hot water solution.
Best suited to: Homes with high hot water demand — larger families, homes without a heat pump — where it can reduce reliance on gas or electric immersion heating. It works alongside an existing boiler or heat pump, which covers the remainder of the hot water demand when solar input is lower.
When it may not make sense: If your home already has a heat pump, it handles hot water needs too, making solar thermal largely redundant. Installations have declined significantly in recent years as most home energy strategies now focus on solar PV and heat pumps together. For many homes, solar PV is simply the more versatile investment.
What you give up: Solar thermal only heats water — it won't reduce your electricity bills. Output drops substantially in winter, so you'll still rely on your boiler or heat pump for much of the year.
For a full picture of how solar thermal works, see our guide: Is Solar Thermal Still a Smart Choice for UK Homes?
Solar Battery Storage
Solar panels generate electricity when the sun shines. Without a battery, any power your home doesn't use in that moment goes straight to the grid — and you buy expensive electricity back in the evening when the panels aren't generating.
A home battery changes that equation. It stores your surplus solar energy during the day and makes it available overnight and during peak evening hours when grid electricity costs most.
Best suited to: Homes that already have (or are installing) solar panels, particularly households that use a lot of electricity in the evenings. Battery storage also works well for people on time-of-use tariffs, where charging overnight on cheap-rate electricity can deliver additional savings.
When it may not make sense: If your solar system is modest in size and your household uses most of that electricity during the day, you may not generate enough surplus to make battery storage cost-effective. It's worth modelling your usage before committing.
What you give up: Batteries add a meaningful upfront cost to a solar installation. They also have a finite lifespan — most home batteries are rated for 10–15 years before capacity degrades noticeably. The financial case depends heavily on your usage patterns, tariff, and how much solar surplus your system generates.
Learn more on our battery storage page, or see the financial breakdown.
Heat Pumps
A heat pump replaces your gas boiler as the primary source of heating and hot water. Instead of burning fuel, it extracts ambient heat from the air or ground outside and transfers it into your home.
The two main types are air-source heat pumps (ASHP), which extract heat from outdoor air and suit most UK homes, and ground-source heat pumps (GSHP), which draw heat from pipes buried in the ground — slightly more efficient, but requiring more land and higher upfront investment.
Heat pumps are significantly more efficient than gas boilers. For every unit of electricity they consume, they typically produce 2.5 to 4 units of heat.
Best suited to: Well-insulated homes with modern radiators or underfloor heating. Properties that are already off the gas grid, or where the boiler is approaching the end of its life, are often a natural fit.
When it may not make sense: This is important: a heat pump in a poorly insulated home will have to work harder to maintain temperature, which reduces efficiency and can mean bills don't fall as much as expected. If your home has significant heat loss through draughty walls, single glazing, or poor loft insulation, tackling insulation first will make a heat pump work far better — and make every other upgrade work better too.
Heat pumps also deliver heat at a lower temperature than gas boilers, which means some older homes may need radiator upgrades to compensate. This is worth factoring into your budget.
What you give up: Heat pumps have higher upfront costs than boilers, though grants (see below) help significantly. They run on electricity, so their running costs are sensitive to electricity prices — pairing them with solar panels helps offset this. They also require outdoor space for the unit.
Biomass Boilers
A biomass boiler works similarly to a conventional boiler, but instead of burning gas, it burns organic matter — typically wood pellets, wood chips, or logs — to generate heat and hot water.
Best suited to: Rural properties, homes that are off the gas grid, or large homes with significant heating demand and outdoor storage space. It can work well alongside solar and other renewables.
When it may not make sense: For most suburban and urban homeowners, a heat pump is a more practical, low-carbon alternative. You'll need space to store fuel, a regular delivery arrangement, and more hands-on maintenance than a gas boiler or heat pump demands.
What you give up: Biomass requires ongoing fuel purchasing and storage — it's not a set-and-forget solution. It also produces particulate emissions (though modern systems are significantly cleaner than older ones) and requires ash removal.
Fuel quality matters a great deal — damp or inconsistent fuel leads to poor combustion and more maintenance. Systems need annual servicing, and fuel supply logistics need careful planning, particularly in rural areas.
Small-Scale Wind Turbines and Micro-Hydro
Small-scale wind turbines can generate electricity for homes in genuinely exposed, rural locations — open farmland, coastal properties, or hillside sites with consistent wind speeds.
When it may not make sense: Domestic wind turbines are not practical for most suburban or urban homes. Planning restrictions, noise requirements, and typically insufficient wind speeds make payback very slow compared to solar. If you're in an exposed rural location, it's worth exploring — otherwise, solar will almost certainly be the better option.
Wind speed is often overestimated at the planning stage. Turbines require more maintenance than solar panels, with moving parts subject to wear. Noise and visual impact can also create friction with neighbours or planners.
Micro-hydro systems generate electricity from the flow of water — a stream or river running through or adjacent to your property. They can generate power continuously, day and night, regardless of weather, which makes them exceptionally valuable where feasible. The geography requirement is specific, but if you have a suitable watercourse, it's worth investigating seriously.
What's Coming Next: Emerging Home Renewable Technologies
Renewable energy technology doesn't stand still. Here are six developments that are actively in development, trial, or early rollout — and that are likely to become mainstream options for UK homeowners over the next few years.
1. Plug-in (balcony) solar: Small plug-in solar panels that connect directly to a household socket — no roof, no installer, no planning permission required. Already mainstream in Germany and the Netherlands. The UK government and Ofgem are actively developing regulations to allow the same here. Particularly exciting for renters and flat owners who currently have no solar option at all.
2. Solar-integrated building materials: Solar roof tiles generate electricity while replacing conventional building materials. Currently more expensive than conventional solar PV, but the cost gap is closing. Best suited to new builds or homes undergoing major roof replacement.
3. Smarter batteries and virtual power plants: Next-generation home batteries that automatically charge when electricity is cheap, or the grid is running on clean energy, then discharge when prices rise. Some systems now allow homeowners to sell stored energy back to the grid. Virtual power plant (VPP) schemes are already live with several UK suppliers.
4. Advanced small wind systems: Quieter vertical-axis turbines designed for rooftop installation in more urban settings. Still niche, but more viable for suburban homes than conventional turbines. Worth watching, particularly for homes where solar is less effective due to shading or orientation.
5. Next-generation heat pumps: Newer models perform more efficiently in colder weather, are smaller and quieter, and increasingly use AI to optimise operation based on weather forecasts and tariff pricing. Current models are already very effective, and the BUS grant is available now.
6. Deep geothermal (regional pilots only): Large-scale projects tapping into geothermal heat several kilometres underground are underway in parts of the UK — notably in Cornwall and some northern regions. Not available for individual homes yet, but part of the longer-term UK energy picture.
Which Type of Renewable Energy Is Right for Your Home?
The honest answer: it depends on your property. Here's a practical framework to help you work it out.
Start with your roof. Solar PV suits most homes with a south, south-west, or south-east facing roof — and even east/west-facing roofs generate useful amounts. If your roof is heavily shaded or unsuitable, solar thermal or a heat pump may be a better first step.
Think about insulation first. Before investing in any heating upgrade, it's worth understanding how well your home retains heat. Good insulation makes every renewable technology work better — and makes heat pumps in particular significantly more effective. If your insulation needs work, tackling that first pays dividends for everything that follows.
Think about your heating situation. Is your boiler approaching the end of its life? That's the natural moment to consider a heat pump instead of a like-for-like replacement. A heat loss survey will tell you whether your home is ready, and what — if anything — needs doing first.
Think about your tenure. If you own your home, all of the technologies in this guide are open to you. If you rent, plug-in balcony solar and negotiating with your landlord about upgrades are the most realistic near-term options.
Think in combinations, not single upgrades — but go at your own pace. Many homes move toward a combination like solar, battery, and a heat pump over time. But the right starting point depends on your home, budget, and priorities. Each step reduces your bills and sets up the next one — you don't need to do it all at once.
For a detailed breakdown of what each upgrade costs and what it saves, see our home energy-efficient improvements guide. And to see what a fully renewable home looks like at the end of the journey, see our net zero energy homes guide.
Government Support for Home Renewable Energy
You don't have to fund the whole journey yourself. Three key schemes are worth knowing about.
The government's Boiler Upgrade Scheme currently offers a grant toward an air source heat pump — one of the biggest single grants currently available for home decarbonisation. ECO4 provides government-funded insulation and energy upgrades for eligible lower-income households, which can include renewable-linked improvements.
How Switch Together Can Help You Go Renewable
Taking the first step toward renewable energy is easier when you don't have to figure it out alone.
Switch Together works with local councils to organise group installations of solar panels, battery storage, and heat pumps — giving you access to vetted, experienced installers and group pricing you couldn't access individually. Our schemes are backed by council partnerships, which means many come with additional local support on top of national grants.
Thousands of UK households have already made the switch through Switch Together schemes. Yours could be next.

Frequently Asked Questions
What is the most popular type of renewable energy for UK homes? Solar panels are by far the most common renewable energy installation in UK homes, with over a million domestic systems now installed. They suit most property types, have relatively accessible installation costs, and begin generating returns from day one — through reduced electricity bills and Smart Export Guarantee payments for surplus energy exported to the grid.
Can I use more than one type of renewable energy in the same home? Yes — and combination systems are increasingly common. The most popular pairing is solar panels with battery storage, which significantly increases the share of solar energy you actually use. Adding a heat pump on top creates a home that generates its own electricity and uses it to heat the house efficiently. This combination forms the backbone of a near net-zero home — though the right order and timing depends on your property and budget.
Do I need planning permission to install renewable energy at home? Most residential solar installations qualify as permitted development in England, Scotland, and Wales — no planning permission needed. Exceptions include listed buildings, conservation areas, and some flat roofs. Air source heat pumps also generally qualify as permitted development, with similar exceptions. Ground source heat pumps require ground works, but usually no formal planning permission. Always check with your local authority if you're unsure.
