Green mortgages

How green mortgage products work

Most green products key off the EPC, the A-to-G energy rating every home is given when sold or let. An EPC of A or B (occasionally C, criteria vary by lender) unlocks either a small rate discount against the equivalent standard product from the same lender, or a cashback at completion. The discounts are typically modest, often a fraction of a percentage point, and cashbacks commonly run to a few hundred pounds. Worthwhile money, but not transformative, which is why the comparison below matters more than the label.

Does green actually beat a standard deal?

A green discount is applied to the pricing of a single lender. If a standard product from another lender is cheaper overall, the green product loses despite the label. Illustration: on a £250,000 remortgage, a green product 0.10 percentage points below the standard rate from the same lender saves around £250 a year. A standard product elsewhere that is 0.15 points cheaper saves more, with no EPC condition attached. Sometimes the green product genuinely is the cheapest option; sometimes it is marketing on top of a mid-table rate. We compare a wide range of lenders and show you the number, not the badge.

Retrofit borrowing for the home you already own

If the home is not efficient yet, the more useful half of the green-mortgage market is the lending that funds improvements. Routes include a further advance from your existing lender (several lenders price these preferentially when the money goes on energy works), a capital-raising remortgage, or a second charge if your current deal should not be disturbed. Typical qualifying works: loft and wall insulation, air or ground source heat pumps, solar panels, upgraded glazing and doors. Government grant support for heat pump installation has also been available in England and Wales; schemes change, so check the current position before pricing the project. We structure the borrowing route around your existing mortgage, not against it.

EPC realities for older Essex stock

Around Romford and across much of Essex, the housing stock is Victorian terraces, interwar semis and 1930s family houses, often solid-wall or early cavity construction. These homes typically sit at EPC D or E. Moving a D to a C is usually achievable with sensible spending: loft top-up, cavity fill where the walls allow it, heating controls, draught-proofing, perhaps glazing. Reaching A or B on a pre-war house is genuinely hard without major works such as external or internal wall insulation. So for many local owners the realistic play is not chasing a green-product threshold; it is retrofit borrowing that cuts bills and improves comfort, with any EPC gain as a bonus. We will tell you which side of that line your house sits on.

Getting the EPC right before you apply

An EPC lasts ten years, and an old certificate often pre-dates improvements you have already made. A new boiler, insulation or glazing fitted since the last assessment may already move the band. If works are done, commissioning a fresh EPC before the application can unlock pricing the old certificate hides. The certificate also carries a recommendations list, which is the sensible starting point for any retrofit plan, because some works improve comfort far more than they move the rating.

Common pitfalls we see

Choosing a green product for the label when a standard product is cheaper overall. Spending on works that barely move the EPC band because nobody read the recommendations list first. Applying against a ten-year-old EPC that undersells the house as it stands today. Assuming every lender defines green the same way, when thresholds and qualifying works differ lender by lender. We sort all four before anything is submitted.
