Don’t be fooled by high-pressure tactics. Fake grants are often used to force a signature before the salesman leaves your home.

Is government funding available for double-glazing right now?

The short answer to this is no. I am being deliberately blunt because there is a vast amount of confusion about the availability of funding—much of it actively promoted, by accident or design, by some national window and door companies solely to drive aggressive sales.

As we navigate 2026, with energy prices remaining a critical concern for homeowners, politicians continuously make promises about transforming the energy efficiency of our notoriously ‘leaky’ UK homes. But we must deal with the reality of the here and now. Let’s look at the facts, expose the marketing scams, and explain why you must be incredibly wary of “strangers bearing gifts.”

1. The “Window Scrappage Scheme” Myth

We need to look back slightly to understand where this confusion comes from. The UK Government introduced a highly publicised Vehicle Scrappage Scheme in 2009.

Window and door companies rapidly capitalised on this familiar language, creating copycat “Window Scrappage Schemes”. The problem? They are entirely fake. There is no government money subsidising these offers. It is simply clever, aggressive marketing.

2. Warning: “Help 2 Buy Windows” is NOT Government Backed

Things get even more confusing for consumers when you read the small print online. Take, for example, heavily advertised commercial websites like Help 2 Buy Windows.

This website sells itself on the availability of ‘grants’ for new energy-efficient windows and doors. The altruistic language used by these companies seems specifically designed to mimic official government programmes.

If this is a problem for these companies, they might want to consider not using a company name which bears such a close resemblance to the official Government Help to Buy Scheme (which was created to help first-time buyers get on the housing ladder through shared equity).

Consumers routinely mistake these commercial sites for government-backed schemes—even when they state at the very bottom of the page (in incredibly small print) that: “Help 2 Buy Windows is in no way affiliated with the UK Government”.

3. The Real Grant: What is the ECO4 Scheme?

To be entirely transparent, there is one genuine, government-backed energy efficiency scheme currently running in the UK, known as ECO4 (Energy Company Obligation), which runs until March 2026.

However, it is vital to understand that this scheme is not available to the general public.

• It is Means-Tested: ECO4 is specifically designed to support low-income, vulnerable, and fuel-poor households.
• Strict Criteria: To qualify, you generally must be receiving specific government benefits (like Pension Credit, Universal Credit, or Income Support) AND live in a property with a very poor Energy Performance Certificate (EPC rating of E, F, or G).
• It Prioritises Insulation, Not Windows: Even if you qualify, the scheme heavily prioritises cavity wall insulation, loft insulation, and boiler upgrades. Double glazing is usually only considered if you currently have zero insulation and single-glazed windows.

(Note: KJM Group does not install through the ECO4 scheme. If you believe you qualify, you must contact your energy supplier directly or visit the official Ofgem website External Link).

4. The “Call the Boss” Discount Tactic

Because there are no general grants available, many double-glazing companies rely on fake discounts to force a sale. This leads to the infamous “Call the Boss” tactic.

You invite a salesman into your home. They stay for three hours, wearing you down. They present a shockingly high price. You refuse. Suddenly, they step outside to “call their boss” to see if they can magically offer you an exclusive 25% discount, “but only if you sign the paperwork tonight.”

This is illegal pressure selling. A reputable local company will give you their best, honest price on day one, and leave the quote with you to decide in your own time.

5. The KJM “No Pressure” Promise

Just to be absolutely clear: KJM Group does not offer fake “government grants” or “scrappage schemes” for energy-efficient windows and doors because, quite simply, they do not exist for the general homeowner.

We also do not supply any windows and doors through third-party lead-generation sites.

We have been working in Hampshire, Wiltshire, Surrey, and Berkshire for more than four decades. We would rather trade off genuine word-of-mouth recommendations than fake discounts. We price our products sensibly at a point which allows us to provide exceptional fitting, and ensures we will still be here in 10 years’ time to honor your guarantee if a problem arises.

• No Pressure: We will not sit in your house at 10 PM trying to exhaust you into signing a contract.
• No Fake Drops: We give you our best, honest price immediately.
• No Commission: Our sales team are not incentivised to “close on the day.”
