The Mouldie Manifesto: Why We Exist (and Why You Need Us)

The Reality of Renting in the UK

Let's be honest: finding a decent rental in the UK is often more stressful than the job you're renting it for. You scroll through Rightmove, spot a place with "Victorian charm" and "high ceilings," and before you know it, you're standing in a queue with ten other desperate souls, ready to sign a 12-month contract after a 10-minute viewing.

But here's the problem: paint can hide a lot of sins.

That fresh coat of Magnolia might look clean today, but it won't keep you warm in January. Those sash windows might look romantic, but they often leak heat faster than you can earn money to pay for it. And that faint musty smell? It's usually the ghost of mould past (and future).

For too long, tenants have been signing leases blind, only to discover the freezing money pit reality when the first frost hits.

Enter Mouldie: Your Rental Wingman

We built Mouldie because we believe you deserve to know the truth before you commit. Not the estate agent's "sales pitch" version of the truth, but the cold, hard, data-backed reality.

Mouldie is the UK's first AI-powered Rental Property & EPC Checker. We are the friend who grabs your arm before you sign the contract and whispers, "Are you sure about those single-glazed windows?"

And the best part? We are totally free. Unlike the rent.

What We Do (So You Don't Have To)

The data regarding a property's thermal efficiency, insulation, and heating systems isn't secret. It's publicly available in the UK Government EPC Register. But let's face it: nobody wants to read through boring PDF certificates full of technical jargon like "cavity wall insulation (assumed)" or "electric storage heaters."

Mouldie does the heavy lifting for you.

We Stalk the Data: We fetch the official government records for the specific address you are interested in.
We Analyse the Risk: Our smart AI agents analyse the walls, roof, windows, and heating systems to calculate a Mould & Cold Score.
We Predict the Bills: We estimate the winter heating costs, so you aren't shocked when the energy bill lands.
We Empower You: We give you specific Red Flags and Green Flags, along with negotiation tips to help you get a better deal (or walk away).

Our Core Features

EPC & Mould Risk Checker: Instantly spot if a flat is prone to damp and condensation.
Heating Bill Estimator: Understand the financial reality of "electric only" flats versus gas central heating.
Negotiation ammunition: Data-backed arguments to help you ask for a lower rent or requested improvements.

Who Built Mouldie?

Mouldie wasn't created by a big, faceless property corporation. We are a small team of enthusiasts and renters who have lived in cold flats, fought with stubborn landlords, and paid too much for heating the street.

We built this tool with the help of advanced AI agents because we wanted to level the playing field. We believe transparency shouldn't cost a penny. Our mission is simple: Dodge the damp. Spot the rot. Save your lungs (and your wallet).

Get in Touch

We are constantly improving Mouldie to make it sharper, faster, and more helpful. If you have a feature request, a bug report, or a horror story about a freezing flat that you want to share, we'd love to hear from you.
