Heatable Solar Review 2026: Costs, Reviews, Batteries, Warranties and How It Compares

Heatable is one of the UK’s best-known online-first home energy installers, offering solar panels, battery storage and other energy-saving upgrades through a fixed-price digital quote process.

The company has built a strong reputation for convenience, fast quoting and customer service.

On Trustpilot, Heatable currently has more than 14,000 reviews and a 4.8/5 TrustScore, with the company also stating that it has served more than 40,000 customers. Trustpilot lists Heatable in the “Solar Energy Company” category as well as heating-related categories.

But is Heatable the right solar installer for your home?

This review looks at Heatable’s solar panel and battery storage service, including pricing, customer reviews, accreditations, installation process, warranties, technology options and how it compares with larger UK energy companies such as Octopus Energy, British Gas and EDF.

Quick verdict: is Heatable solar worth considering?

Heatable is worth considering if you want a fast online quote, clear pricing, solar panel and battery storage options, and a company with a strong customer review profile.

Its main advantage is convenience. Rather than relying on a lengthy sales process, Heatable’s model is built around online pricing, remote assessment and installation through a managed network of engineers and installers.

However, Heatable may not be the best fit for every household. If your roof is unusually complex, you want a highly bespoke system design, or you want to bundle solar with an energy tariff from your supplier, you should compare Heatable with at least two other MCS-certified installers before committing.

🔑 Key takeaways:

• Best for – Homeowners wanting fast quotes, clear pricing and solar-plus-battery installation
• Main strength – Digital-first quote process and strong customer feedback
• Main limitation – Less tariff bundling than large energy suppliers
• Trustpilot score – 4.8/5 from more than 14,000 reviews
• Warranty – 12-month workmanship protection plus manufacturer warranties
• Good for batteries? – Yes, especially for homeowners wanting solar and storage together
• Should you get other quotes? – Yes. Compare Heatable with a local MCS installer and one national provider

Who Is Heatable?

Heatable started as an online heating installation company before expanding into broader home energy upgrades, including solar panels and battery storage.

Its core proposition is simple: homeowners answer questions online, receive a fixed quote, and then have the installation handled by Heatable’s network. This is different from the traditional solar sales process, where customers often need several calls, home visits and manual quote revisions before seeing a firm price.

Heatable says its benefits include instant online prices, customer service, finance options and 12 months of workmanship protection. Its Trustpilot profile also states that it is a Which? Trusted Trader and has more than 40,000 customers.

For homeowners who dislike pushy sales calls, that online-first process is a major selling point.

Heatable solar panels and battery storage

Heatable offers domestic solar panel systems and battery storage installations. Battery storage is especially relevant for UK households because much of a solar system’s generation happens during the day, when many people are out or using less electricity.

A battery allows you to store excess solar electricity and use it later, reducing the amount you import from the grid. Batteries can also help households make better use of time-of-use tariffs, depending on the system and supplier.

Battery prices have fallen significantly over the past decade, although they are still a major part of the upfront cost. Recent UK reporting cites average installed home battery costs of around £5,500 for a 4kWh battery, while some suppliers advertise smaller batteries from lower price points.

For many homes, the strongest case is not solar panels alone. It is solar panels plus battery storage, especially where the household has high daytime or evening electricity use, an EV, a heat pump, or access to a good export/import tariff.

Heatable pricing and value for money

Heatable’s main pricing advantage is transparency. Its online quote journey is designed to give homeowners a clearer idea of cost before committing to a survey or sales conversation.

That matters because solar pricing can be difficult to compare. Two quotes may differ because of:

• Number and wattage of panels
• Inverter type
• Battery size
• Scaffolding costs
• Roof complexity
• Bird protection
• Monitoring hardware
• Warranty length
• Finance charges
• DNO/grid application requirements

Large suppliers such as Octopus Energy, British Gas and EDF may offer strong packages, but their quotes can be harder to compare if they include tariff incentives, finance, partner installers or bundled energy services.

The most sensible approach is to collect three comparable quotes:

1. Heatable
2. A local MCS-certified solar installer
3. A large national provider

Then compare the actual system specification, not just the headline price.

A cheaper quote is not always better if it uses lower-output panels, a smaller battery, weaker monitoring, less useful warranties or a less suitable inverter setup.

How much can solar panels save?

Solar panel savings vary widely. Any article that gives a single saving figure without context is oversimplifying.

Your savings depend on:

• System size
• Roof direction and pitch
• Shading
• Electricity usage
• Daytime consumption
• Battery storage
• Export tariff
• Import tariff
• Installation cost
• Whether you pay upfront or use finance

Solar panels can reduce bills by generating electricity for use at home. Any excess electricity can potentially be sold back to the grid through the Smart Export Guarantee, depending on eligibility and tariff. The best export rates often come with conditions, such as needing to use the same company for supply and export or having a battery.

Installation process

Heatable’s process is built around speed and simplicity.

A typical journey looks like this:

1. The homeowner completes an online quote form.
2. Heatable provides an estimated or fixed system price.
3. The property and roof are assessed.
4. A final design is confirmed.
5. Scaffolding, installation and electrical work are scheduled.
6. The system is commissioned and documentation is supplied.
7. The homeowner receives aftercare and warranty information.

The major advantage is convenience. The possible drawback is that remote-first quoting may not capture every roof complication at the start. For example, shading, roof condition, unusual electrics, access problems or DNO constraints may affect the final recommendation.

That does not make the model bad. It just means homeowners should confirm what is included before paying a deposit.

Before accepting a quote, ask:

• Is scaffolding included?
• Is bird protection included?
• What panel and inverter brands are being used?
• What battery size is included?
• Is monitoring included?
• Who handles the DNO application?
• Is the installer MCS certified?
• What workmanship warranty applies?
• Are there any likely extras?

Accreditations and trust signals

For UK solar, accreditations matter. Homeowners should usually look for an MCS-certified installation, especially if they want to access export payments through the Smart Export Guarantee or need recognised installation documentation.

Heatable states that it is a Which? Trusted Trader and provides 12 months of workmanship protection. Its Trustpilot profile also highlights upfront fixed pricing, customer service and solar/battery services.

When comparing installers, do not rely on brand name alone. Check:

• MCS certification
• Insurance-backed guarantees
• Workmanship warranty
• Product warranties
• Public reviews
• Complaints handling
• Who actually installs the system
• Whether subcontractors are used
• Whether documentation is supplied promptly after installation

This is especially important with large national brands, where the company selling the system and the company installing it may not always be the same.

Warranty and aftercare

Heatable states that customers receive 12 months of workmanship protection after installation. Product warranties will depend on the panels, inverter and battery selected.

Typical solar warranties may include:

Component	Typical warranty range
Solar panels	Often 15–25+ years product/performance cover
Inverter	Often 5–12 years, sometimes extendable
Battery	Often 10 years, depending on brand and cycles
Workmanship	Varies by installer

The key point is that a long panel warranty does not automatically mean the whole system is covered for the same period. Panels, inverters, batteries and workmanship are usually covered separately.

Before choosing Heatable or any installer, ask for the warranty terms in writing.

Customer reviews

Heatable’s customer review profile is one of its strongest selling points. Trustpilot currently shows more than 14,000 reviews, a 4.8/5 TrustScore, and a high proportion of 5-star reviews.

Trustpilot’s review summary says customers frequently praise the company’s service, staff, product quality, price and user experience, while some negative feedback mentions issues such as delays or assessment problems.

That said, review platforms should be interpreted carefully. Trustpilot itself notes that it does not fact-check individual review claims, though it uses automated screening and moderation systems.

The practical takeaway: Heatable has strong public customer sentiment, but you should still inspect the quote, warranty, installer credentials and system specification before committing.

Heatable vs Octopus Energy, British Gas and EDF

Category	Heatable	Large energy suppliers
Quote process	Fast, online-first, fixed-price focused	Often more survey-led or package-led
Pricing clarity	Strong upfront visibility	Can be harder to compare because of bundles and finance
Installer model	Managed installer network	Often partner or regional installer networks
Solar + battery	Core part of the offer	Available, but varies by supplier
Tariff integration	More limited	Stronger, especially with supplier-owned tariffs
Brand familiarity	Growing challenger brand	Higher mainstream recognition
Customer reviews	Strong Trustpilot profile	Mixed depending on supplier and installation partner
Best for	Fast quote and straightforward installation	Tariff bundling, energy account integration, national scale

Heatable’s biggest advantage is simplicity. Large suppliers’ biggest advantage is ecosystem: energy tariffs, export tariffs, finance, billing and smart-home integrations may all sit under one roof.

For many homeowners, the right answer is not obvious until the quotes are compared side by side.

Pros and cons of Heatable solar

Pros

• Strong Trustpilot score and large review base
• Solar and battery storage available
• Fixed-price positioning
• 12-month workmanship protection
• Useful option for homeowners who dislike sales-heavy quote processes
• Which? Trusted Trader status stated on Trustpilot profile

Is Heatable right for you?

Heatable is likely to be a good fit if you want a simple online quote, a solar panel and battery storage package, and a company with strong customer feedback.

It may be especially suitable if:

• You want a quick price without a long sales process
• You are considering solar panels and battery storage together
• You value online convenience
• You want a nationally recognised installer rather than a very small local firm
• You want clear communication and documented aftercare

You may want to compare more carefully if:

• Your roof has heavy shading
• You need a complex battery setup
• You want a specific panel, inverter or battery brand
• You want to optimise around a particular energy tariff
• You prefer an in-depth in-person technical survey before receiving a quote

Final verdict

Heatable is a strong contender in the UK residential solar market because it combines online pricing, solar and battery installation, strong customer reviews and a straightforward buying process.

Its biggest strength is convenience. Its biggest weakness is that it may not offer the same level of bespoke system design or tariff integration as some specialist installers or major energy suppliers.

For most homeowners, the best next step is to get a Heatable quote and compare it against a local MCS-certified installer and one national supplier. Look beyond the headline price and compare the full system specification, battery size, warranties, monitoring, scaffolding, DNO handling and aftercare.

Used properly, Heatable can be a sensible option for homeowners who want a clear, modern route into solar panels and battery storage without a drawn-out sales process.
