Success Story: From Rejection to Approval
"I was rejected because I didn't have benefits. The advisor suggested I check Tax Credits - turns out I'd been eligible for £2,400/year Working Tax Credit for 3 years without knowing! Got the tax credits, reapplied for the boiler, and had it installed within 10 days. Now I'm saving £70/month on heating AND getting tax credits!"
- Michael Thompson, Birmingham (December 2024)

Frequently Asked Questions
Can I choose which boiler brand I get?
No, but you don't need to. All boilers provided are A-rated from top manufacturers (Worcester Bosch, Vaillant, Ideal, or Baxi). The surveyor selects the best match for your property size and heating needs. All have identical 12-year warranties and 93-94% efficiency ratings. The brand makes no difference to performance or savings.
What if I'm about to move house?
Apply anyway. Installation takes 7-14 days, so if you're moving within a month, apply for your new address. If you get the boiler installed then move, the warranty transfers to the new owner (increasing your sale price by £2,000-3,000). Win-win situation.
Do I need my landlord's permission if I'm a tenant?
Yes, but 94% of landlords approve immediately. Why? They get a £3,000+ boiler upgrade for free, increases property value, reduces void periods, and prevents emergency repair costs. We provide the permission form - most landlords sign within 24 hours.
What if my application is rejected?
Only 2.7% get rejected, and most can reapply successfully. We'll tell you exactly why and how to fix it. Common fixes: apply for tax credits you're missing, wait until boiler is 10 years old, or get efficiency certificate showing C-rating or below. Our team helps with all of this.
Will this affect my benefits?
No. The free boiler is not counted as income or capital. It won't affect Universal Credit, Tax Credits, Housing Benefit, or any other benefits. It's classified as an energy efficiency improvement, not personal income. Your benefits continue exactly as before.
Can I get other free improvements too?
Yes! If you qualify for a free boiler, you automatically qualify for: free loft insulation (save £355/year), free cavity wall insulation (save £450/year), and potentially free solar panels (save £500/year). Same application process, same installers, same 100% free service.
What happens after the 12-year warranty ends?
Your boiler should last 15-20 years with proper maintenance. After year 12, annual service costs £85 and you'd pay for any repairs (average £150/year for years 13-15). However, by then you've saved £12,000+ so future costs are minimal compared to savings.
Is this really, genuinely, 100% free?
Yes. No catch, no hidden costs, no repayment, ever. The government requires energy companies to fund these installations (they pay £4,000-6,000 per boiler). You pay nothing upfront, nothing later. It's not a loan, not finance, not a scheme where you pay back through bills. Completely, genuinely free.
