Let me paint you a picture
You’ve spent months scrolling through Rightmove. You’ve fallen in love with a Georgian townhouse, a Victorian farmhouse, or maybe a 17th-century cottage with original timber beams and an Inglenook fireplace you could park a small car in. The estate agent tells you it’s “full of character.” The photos are dreamy. The survey comes back with a few niggles, nothing too alarming, and you exchange contracts with a heart full of plans.
You move in. You start sketching out ideas; knocking through to open up the kitchen, swapping those draughty sash windows for something with a bit more thermal performance, maybe converting the loft. Replacing a bathroom. It all feels exciting, achievable, yours.
Then someone mentions the words “listed building consent.”
And that’s where things get complicated.
First, let’s talk about what “listed” actually means
A grade II listed building isn’t just an old house. It’s a building of special architectural or historic interest with legal protection. There are roughly 400,000 listed buildings in england alone, and around 92% of them are grade II. So statistically, if you’rebuying a period property, there’s a very real chance it falls into this category.
Being listed means the building is protected under the planning (listed buildings and conservation areas) act 1990. It means that certain changes (sometimes even changes you’d consider completely routine) require a separate planning application called listed building consent, on top of any regular planning permission you might need. It is also very important to note that carrying out works to a listed building without listed building consent is a criminal offence. It may also be necessary to apply for planning permission in addition to listed building consent in order to carry out works to a listed building.
And here’s the part most people don’t fully grasp until it’s too late: the protection covers everything. Not just the external walls. Not just the “heritage bits.” Everything; The exterior curtilage and outbuildings; the interior, the layout. The historic fabric of the building which could include but isn’t limited to original floorboards, plasterwork, fireplaces, and even the historic paint layers on the walls.
That’s the law.
The gap I have issue with
Here’s something that genuinely surprises people when I tell them: when you buy a listed property, the vendor is under no legal obligation to provide you with a heritage statement.
No requirement. No standard. No tick-box in the conveyancing process.
Think about that for a moment. When you buy a house, you commission a survey. Your solicitor carries out searches. You check the EPC rating. You ask about the boiler. These are all normal, expected parts of due diligence. But the one document that would actually tell you what you can and can’t do with your newly purchased listed building? There’s no rule that says it has to be provided. Most of the time, it isn’t. And most buyers don’t even know it exists.
A heritage statement (sometimes called a heritage impact assessment) is the document that describes a building’s significance, its historical, architectural, and cultural value. It sets out what makes it special, what its key features are, and how any proposed changes might affect that significance. When an architect submits a listed building consent application (yes they usually require drawings in the application too), the heritage statement is one of the most critical pieces of the puzzle. It’s what the heritage officer at the local planning authority will reference when deciding whether your proposed changes are acceptable.
Without one, you’re essentially flying blind.
You don’t know which features are considered the most significant. You don’t know what the previous owners were or weren’t given consent to change. You don’t know what the local authority’s approach to this building has been historically. And you certainly don’t know which of your renovation dreams are likely to sail through and which ones are going to cause a very long, very expensive conversation with a conservation officer.
“But surely I can just ask for permission?”
You can. Absolutely, you can. And sometimes it works out fine.
But I’ve sat with enough clients post-purchase to know that the reality is often disappointing, and that disappointment could frequently have been avoided (or at least anticipated) with better information upfront.
Let me be honest with you, because that’s what you deserve: heritage professionals are, broadly speaking, not enthusiastic about change. That’s not a criticism. It’s their job to protect these buildings, and they take it seriously. The conservation officer at your local planning authority is there to safeguard the historic environment for future generations. They are not there to help you create an open-plan kitchen-diner.
I suggest considering yourself a guardian of the property, not the owner. My colleague Phill often jokes with clients that “the building owns you now…”. You are there to take care of it, to preserve it, not add endless extensions which you will have to fight tooth and nail to get consent for.
What that means in practice is that listed building consent applications are often met with resistance, negotiation, or refusal, particularly for changes that would remove or significantly alter historic fabric. Things like:
- Replacing original windows with modern double glazing (even energy-efficient alternatives are scrutinised carefully and often refused on the primary elevations)
- Removing internal walls, even non-structural ones, if they’re considered significant
- Installing underfloor heating beneath historic floors
- Adding roof lights or dormer windows
- Fitting a contemporary kitchen or bathroom in a particularly significant room
- Re-routing services in a way that involves cutting through historic masonry or drilling through timbers.
None of these are impossible. Many things can be achieved with the right approach, the right design, and the right application. But they require time, expertise, and often compromise. And if you bought the house imagining none of this complexity, that’s where the disappointment creeps in.
The £1,000 surprise
Here’s another thing that tends to catch people off guard: commissioning a heritage statement isn’t free.
A heritage statement for a typical listed property, one that properly addresses the building’s history, significance, and the context of any proposed changes, will generally cost in the region of £1,000. Often more, depending on the complexity of the building and the scope of the works proposed. And that’s before you’ve even started the planning application itself, before architect’s fees for the design, and before any actual building work.
For a buyer who’s just stretched themselves to the limit to purchase their dream home, an unexpected £1,000 cost is a sting. Especially when, if someone had just mentioned it during the buying process, it could have been commissioned earlier, factored into negotiations, or even requested from the vendor.
That’s the thing about this cost: it’s not inherently unreasonable. You’d happily pay £1,000 for a proper survey. You’d pay more than that for a solicitor. The heritage statement is just as legitimate a piece of due diligence. The problem is that nobody positions it that way.
It gets framed, if it gets framed at all, as a cost you incur when you want to do something. But really, it’s a cost you incur to understand what you’ve bought.
What a heritage statement actually tells you
Let’s make this concrete, because I think when people hear “heritage document” their eyes can glaze over a bit. So, here’s what a good heritage statement will actually do for you as an owner.
It tells you the building’s history. When was it built? Who built it? What was it used for? Has it been extended, altered, or subdivided over the years? Understanding this context is fascinating in its own right, but it also helps you understand why certain features exist and why they’re valued.
It identifies the key significance. Not everything in a listed building is equally important. A heritage statement will flag what the heritage officer is really going to care about, the original staircase, the Edwardian tiling, the 18th-century panelling, an historic bread oven, versus the parts of the building where there’s more flexibility because they’re of less heritage significance.
It informs your planning conversations. When you come to us as architects and say “I want to do X,” the heritage statement is one of the first things we reach for. It helps us advise you honestly on what’s likely to be achievable, how to frame the application, and what alternatives might exist if your first preference is going to be difficult to justify.
Not only are they essential for an application. A well-prepared heritage statement, submitted as part of a listed building consent application, can make the process smoother because it demonstrates to the local authority that you understand the building’s significance and have thought carefully about how your proposals relate to it. Conservation officers are human. They respond better to applicants who clearly get it.
It protects you. If you’re ever in a dispute about what’s permissible, or if a previous owner made unauthorised changes that you weren’t aware of, the heritage statement forms part of your evidence base. It’s documentation of the building’s state and significance at a point in time.
The comparison that should already be standard
We routinely tell buyers: commission a survey. It’s non-negotiable advice. You wouldn’t buy a house without knowing if the roof needs replacing or whether there’s damp in the basement.
So why aren’t we routinely saying: commission a heritage statement?
I think it comes down to awareness, or the lack of it. The survey is a known quantity. Every buyer has heard of it. It’s expected. The heritage statement, by contrast, is still largely a document that lives inside the professional world of architects and conservation officers. It hasn’t crossed into mainstream property-buying culture the way I think it should have when discussing listed properties.
And that’s a genuine problem, because the consequences of not having one up front can be significant. Disappointed buyers. Wasted application fees. Refused consents. Protracted negotiations. In some cases, enforcement action against unauthorised works carried out in ignorance. These outcomes are not rare. They’re common. And many of them could be avoided.
If I were writing the rules, and one day I hope someone in a position to do so takes note of this, I’d make it standard practice for heritage statements to be included in the sale pack for any listed building; or at least a “heritage statement of facts”, just as EPCs are currently mandatory. Vendors commission one before listing. Buyers receive it as part of their due diligence pack. Everyone enters the transaction with their eyes open.
Until that day, the next best thing is for buyers to know to ask.
What you should do if you’re buying a listed property (or even just considering it)
I want to end this practically, because knowing there’s a problem is only useful if you know what to do about it.
Ask the vendor for the heritage statement. It may already exist, especially if any planning applications have been submitted in the past. If it does, ask for it. If it doesn’t, you now have a negotiating point, you can request that the vendor commissions one or factor the cost into your offer.
Ask your solicitor to check the planning history (or search yourself). They can look at what listed building consent applications have been made and whether there are any breaches or enforcement notices. This won’t replace a heritage statement, but it’ll give you a picture of the building’s recent history.
Talk to an architect who understands heritage. Not all architects work with listed buildings regularly. Find one who does, ideally before you exchange rather than after. A brief conversation can save you a lot of heartache. We can tell you fairly quickly whether your ambitions are likely to be achievable, and what the process could look like.
Reframe the heritage statement as part of your buying costs. Budget for it the same way you’d budget for a survey. Around £1,000, potentially more for a complex building. Commission it early so you can make informed decisions about what you’re buying.
Go in with realistic expectations. Living in a listed building is a privilege. These are genuinely special places, and the pleasure of calling one home is something a lot of people deeply value. But it comes with responsibilities. Changes take longer and cost more. Some things won’t be possible at all. If you can make peace with that before you buy, you’ll be a much happier owner.
Don’t assume small changes are exempt. This is a really common misconception. The threshold for what requires listed building consent is lower than most people expect. If in doubt, ask. It’s always better to check than to proceed and find yourself in breach.
A final word
I love heritage buildings. I’ve spent years working with them, and there’s nothing quite like standing in a 300-year-old structure and feeling the layers of history beneath your feet. These buildings are irreplaceable. They deserve protection.
But the people who own them, who maintain them, heat them, live in them day to day, deserve to be properly informed. They deserve to know what they’re getting into before they sign on the dotted line, it’s not just “character” it’s responsibility too. They deserve to have the full picture, not discover it piece by piece after they’ve moved in.
The gap between the world of heritage professionals and the world of everyday property buyers is a real one, and it causes real harm. Not dramatic harm, usually it’s just cost, frustration, and dashed hopes. But it’s harm that’s almost entirely preventable.
So, if you’re buying a listed building: ask for a heritage statement. And if you’re selling one: do the right thing and have one ready.
It’s a small shift that could make an enormous difference.
