Barclays Greener Home Loan

The Barclays Greener Home Loan is a personal loan from Barclays for home improvements that make a property more energy efficient. It is open to Barclays current account customers only, and you need to be registered for Online Banking or the Barclays app to apply¹. It runs over 2 to 5 years, and the rate you are offered depends on your circumstances, so the bank's own site carries today's figures¹.

What makes it different from an ordinary personal loan is the cashback. The reward is not automatic: you have to meet the installer rules, keep the paperwork, and still have an open loan that is not in arrears when you claim¹.

The loan sits alongside several other ways to pay for green work, including Barclays' own home improvement loan and additional mortgage borrowing, and green products from building societies and credit unions. This page sets out who can apply, what qualifies, how the cashback is earned and claimed, and what happens if repayments become difficult.

What the Barclays Greener Home Loan is and how it works

It is an unsecured personal loan, not a mortgage, so it is not secured against your home. You borrow a fixed sum over a set term of 2 to 5 years and repay it in monthly instalments¹. Because it is unsecured, the interest rate you are offered reflects your credit history and circumstances rather than being tied to your property, and the bank's site has the current rates.

The green element is the cashback reward, which Barclays describes as "a one-time cash reward to help with the cost of adding solar panels, insulation, a heat pump and more to your home"². It is a reward for spending the money on qualifying work, not a discount on the interest rate. That distinguishes it from a green mortgage, where the incentive is usually a lower rate on the borrowing itself.

Green home finance is a growing part of the UK lending market. A UK Finance report on greening homes, published on 29 January 2026 and backed by the UK's lending sector, looked at unlocking demand for this kind of borrowing³. Barclays is not alone: NatWest has offered cheaper rates for people with energy-efficient homes⁴, and Nationwide Building Society has offered 0% additional borrowing for green home improvements⁵.

If you already have a Barclays mortgage, there is a separate route. Existing customers can apply for additional borrowing, and the bank says that because you already have a mortgage with it, applying is easy, though it will still ask a few questions⁶. That is a different product from the Greener Home Loan and is secured against your home.

Who can apply: Barclays current account customers only

The eligibility rule is the first thing to check, because it rules out most people. Barclays states plainly that "this offer is open to Barclays current account customers only"¹. You must also be a UK resident, and you need to be registered for Online Banking or the Barclays app to apply¹.

If you hold a Barclays current account or a Barclaycard, you can get a personal price quote with no credit footprint, which means checking what you would pay does not affect your credit score⁷. The bank says it will tell you your loan rate before you apply⁸. The same pre-check is available on its holiday loan for customers with a current account or a Barclaycard⁹.

The wider lending rules apply too. Barclays says you must be 18 or over and resident in the UK to apply for lending with it¹⁰. Its home improvement loan, a separate product, requires a Barclays current account or Barclaycard, UK residency and an age of 18 or above to apply online⁷.

A Barclays Basic Current Account is available to people who are not eligible for another current account with the bank, do not have a UK account, do not have standard ID, or are experiencing financial challenges¹¹. If you bank elsewhere, the Greener Home Loan is not open to you, but green and home improvement borrowing is offered by credit unions, building societies and other lenders, and the green and home improvement borrowing page sets out the alternatives.

How the cashback reward is earned

The cashback is conditional, and the main condition is how you spend the money. Spend less than that on qualifying work and the reward is not available.

Two further conditions apply. Cashback is only paid if you have an open loan and are not in arrears¹. And you can only claim one cashback reward per property¹. If you top up an existing loan, only the additional Greener Home borrowing qualifies for the reward¹.

Cashback on borrowing is a familiar feature of the mortgage market, and the sums involved elsewhere give a sense of scale. Barclays' own Greener Home Reward, which is tied to having a residential mortgage with the bank, is a separate scheme from the loan cashback².

Which home improvements qualify, and which do not

The loan is aimed at energy efficiency work. Barclays lists air source heat pumps, ground source heat pumps and biomass pellet boilers as low carbon heating that qualifies¹. The Greener Home Reward, the mortgage-linked scheme, names solar panels, insulation and heat pumps among the improvements it covers².

There is an important exclusion. Changes to existing energy-efficient features are not eligible for cashback¹. In other words, replacing something that is already energy efficient is not the kind of upgrade the reward is designed for.

Other lenders' green products show how the boundaries are usually drawn. Skipton Building Society's Green Additional Borrowing permits solar panels, insulation, new windows and doors, ground or air source heat pumps and biomass boilers¹². Nationwide's Green Additional Borrowing excludes work that means you cannot live in your home during installation, routine maintenance, green design features such as green roofs or living walls, damp proofing, gas boilers, all like-for-like upgrades, and upgrades to the structure of the home such as replacing construction elements⁵. Salford Credit Union's green loan covers solar panels, heat pumps, double glazing, insulation and any other energy efficient home improvement¹³.

The Barclays home improvement loan, a general-purpose alternative, cannot be used for business reasons, investments including stocks and shares, timeshares, purchasing property (home improvements are fine), gambling-related expenses, repaying county court judgments, or a purchase made by combining it with other loans⁷. The holiday loan carries the same list of prohibited uses⁹.

Installer rules and claiming the cashback

Who does the work matters as much as what the work is. Barclays requires a VAT registered installer or tradesperson, and an MCS registered one for solar energy and low carbon heating¹. The Greener Home Reward requires a TrustMark registered or Microgeneration Certification Scheme certified business to complete the work².

The MCS requirement is not unique to Barclays. Installers that fit a heat pump with a grant from the Boiler Upgrade Scheme must be certified by MCS or an equivalent scheme¹⁴. Which? has called on the government to introduce mandatory certification of heat pump installers, and until that happens it says financial providers should require MCS certified installers¹⁴.

Once the work is done, the claim depends on evidence. For the mortgage-linked reward, Barclays asks customers to make sure the installer meets its rules, and the reward is a one-time cash payment². For the loan, the 90% spending rule and the open, non-arrears loan condition are what the claim turns on¹.

How to apply and how quickly the money arrives

Applications are made online. Barclays says it usually takes less than 10 minutes to apply¹. The same figure appears across its lending products: the home improvement loan says most people apply in less than 10 minutes in Online Banking or the app⁷, and the personal loan says it usually takes less than 10 minutes, longer if you are not registered for Online Banking or the app⁸.

The money usually arrives quickly. If you sign your agreement online between 5am and 11pm, you will usually get your money straightaway, within a few minutes¹. The home improvement loan adds detail: up to a couple of hours if you do not bank with one of the main UK high street banks, and before 9am the next day if you sign after 11pm⁷. The two Barclays pages describe the after-11pm timing slightly differently, so treat the exact next-day time as approximate.

If you are weighing up whether to borrow at all, the how to apply for a loan page covers the process, and how personal borrowing works explains the mechanics. Before applying, it is worth checking what a lender will look at: loan affordability checks sets out what lenders must assess.

What can go wrong: arrears, top-ups and EPC ratings

Missing payments on any loan has consequences. Those consequences are most severe where borrowing is secured, but the credit file effect applies to unsecured loans too.

If you fall behind, there are options. Your provider may allow you to add your arrears to the total amount you owe and pay them back over the lifetime of the loan¹⁵. Breathing Space allows you to include arrears on essential bills such as rent, mortgage, gas and electricity, water, hire purchase, council tax and business rates, income tax and National Insurance, as well as non-priority debts such as credit cards, overdrafts, loans, catalogues and family or personal debts¹⁶. Barclays says that where income has fallen it may be able to work with customers on a repayment plan, and that some banks have eased restrictions on savings accounts and reduced interest rates on arranged overdrafts¹⁷.

On top-ups, the rule is narrow: only the additional Greener Home borrowing qualifies for the reward¹. On EPC ratings, the bank is explicit that there is no guarantee that any eligible home improvement you make under the loan will improve your property's EPC rating¹, and the same wording applies to the Greener Home Reward². If a better rating is the point of the work, that is worth knowing before you borrow.

Help, complaints and scam warnings

Barclays says it shares the latest guidance and information on its website, shows warning messages when you use its app or Online Banking to make a payment, and educates people about scams using social media, press releases and adverts¹⁸. It has partnered with Get Safe Online on a tool to check whether a website is known to be problematic¹⁹.

If someone calls claiming to be from Barclays about your loan, there is a way to check. The bank says that if it calls you, it will send a secure notification you can view in the Barclays app, showing the name of the colleague you are speaking to, and you can confirm you have got the notification so it knows it is you too²⁰. You can ask for this¹⁹.

The bank's own rules for spotting a fake call are firm. Never call back on the same number, even if you find a phone number online and it looks like one of ours¹⁹. Scammers can keep your line open, so call from a different phone if possible, or try calling a friend first to check the line has cleared¹⁹. Call 159, a safe number set up by Stop Scams UK, which will connect you securely to Barclays¹⁹. Barclays says it will never send you a link in an SMS message, and will never contact you by phone, text or email to ask you to move money to another account, help with an internal investigation, give device access, or reveal your PIN, PINsentry or other membership details¹⁹. It also never discloses personal details to prove identity and never texts unexpectedly with a link to make a payment¹⁹. Never reveal personal information, your PIN, PINsentry codes, mobile activation codes, QR codes or Online Banking passcodes²⁰.

If something goes wrong with the loan itself, you can complain to Barclays first. If you are not satisfied with its final response, you can take the complaint to the Financial Ombudsman Service, which is free to consumers. The ombudsman publishes quarterly complaints data by product; in the first quarter of 2026/27 it recorded 92 complaints opened about Bounce Back Loans and 27 about Help to Buy and Shared Equity Loans²¹. In the first quarter of 2025/26 it recorded 97 about Bounce Back Loans²², and in the third quarter of 2025/26 it recorded 21 new complaints about Guarantor Loans²³. The ombudsman also publishes case studies, including one about a consumer who complained about a loan her ex-husband took out in her name, where the reason for the loan was recorded as "home improvements"²⁴.

If you are separating from an abusive partner, Surviving Economic Abuse lists the support Barclays can provide, including account security, changing how you receive statements and letters, removing the abuser as a named cardholder from your credit cards, and removing you from any joint accounts or freezing joint accounts²⁵.
