Nobody's Paying Extra for Insulation: The Retrofit Rent That Never Arrived

Let's get the heresy out of the way early: in Brighton, the green premium is largely a myth. There, I've said it.

For years, landlords have been told a comforting story. Retrofit your property, hit that EPC C, and tenants will reward you with higher rents, longer stays, and warm feelings all round. It's a narrative that's been repeated so often — in trade press, government consultations, and manufacturer brochures — that it's become accepted as fact.

It isn't. Or at least, not here, and probably not at the rents that matter.

What the Market Actually Shows

Brighton's rental market is defined by one overwhelming force: scarcity. With more people wanting to live here than properties to house them, tenants choose based on location, size, condition, and price — roughly in that order. An EPC rating sits well down the list, somewhere below 'does it have a washing machine'.

Talk to letting agents around the city and the pattern repeats. A well-presented two-bed in Fiveways lets in days at full asking rent whether it's a D or a C. A draughty flat in a sought-after street near the seafront doesn't struggle either. Meanwhile, the properties that do sit empty tend to be overpriced or poorly maintained — not under-insulated.

Some green features do help, to be fair. An efficient boiler means lower bills, and lower bills matter in a cost-of-living squeeze. Solar panels on a house can be a genuine selling point. But 'the tenant saves £40 a month' is not the same as 'the landlord earns £40 more a month', and conflating the two is how the premium myth survives.

The Bill Is Real, Though

Here's the uncomfortable part. While the rental reward for retrofitting is thin, the cost of not doing it is growing. EPC rules keep tightening in one direction, mortgage lenders increasingly offer better rates for efficient homes, and the direction of travel is unmistakable even if the deadlines keep shifting.

So landlords face a strange asymmetry: spend £10,000–£25,000 upgrading an older terraced property — and Brighton is full of them, beautiful and brick-solid and thermally hopeless — and you'll recover very little of that through rent. Do nothing, and you risk a stranded asset further down the line.

What Sensible Landlords Are Doing Instead

The pragmatic response we're seeing locally falls into three camps:

The minimalists. Do the cheap, high-impact work — LED lighting, draught proofing, smart thermostats, loft insulation — and stop at whatever rating that achieves. Don't chase a letter for its own sake.

The repurposers. Some owners are asking whether the property should remain a rental at all. We've watched several Brighton landlords take hard-to-retrofit stock out of the rental market entirely — selling, converting to commercial use, or emptying the property into storage while deciding. It's not the outcome housing campaigners want, but it's a rational response to economics that don't add up.

The long-holders. Those planning to keep properties for decades are doing full retrofits as capital projects, timed to major works, and writing off any 'premium' fantasy altogether.

The Honest Conclusion

The green premium exists in theory and in estate agent brochures. In Brighton's rental market, it mostly doesn't exist in practice — because tenants here are paying for location and scarcity, not thermal efficiency, and they'll keep doing so as long as the housing shortage does the landlord's marketing for them.

That's not an argument against retrofitting. It's an argument for honesty about who pays for it — because right now, it's landlords, and pretending otherwise helps nobody plan properly.
