Questions to Ask at a Flat Viewing That Every First Time Buyer Needs

Most viewers ask about the boiler and leave. These are the questions that actually tell you whether a flat is worth buying.

Why most viewings are a waste of time

Most first time buyers walk into a flat viewing and spend twenty minutes admiring the kitchen and checking if the shower pressure is decent. Both fine things to notice. But neither will tell you whether you're about to buy a financial headache that takes years to untangle.

Flats are different from houses. You're not just buying four walls and a ceiling. You're buying into a building, a freeholder relationship, a managing agent, a service charge structure, and a lease that has a countdown clock ticking on it. Get those things wrong and no amount of nice tiles will save you.

The questions below are the ones that separate a confident buyer from a hopeful one. Ask them at the viewing, or follow up with the estate agent the same day. If anyone gets cagey or can't answer, that itself is useful information.

The lease questions you cannot skip

Start here, every time. Ask how many years are left on the lease.

Anything below eighty years is a problem. Once a lease drops below eighty years, extending it becomes significantly more expensive because of something called the marriage value calculation. Mortgage lenders get nervous below eighty years too, and some won't lend at all below seventy. If the lease is already short, you need to know before you fall in love with the place.

Also ask whether the seller has already started a formal lease extension. If they have, that process can sometimes be assigned to you as the buyer, which is worth knowing.

Then ask about the ground rent. Since the Leasehold Reform (Ground Rent) Act 2022, new leases in England and Wales must have a ground rent of zero. But older leases can still have ground rents that double every ten or twenty five years. A doubling ground rent is a mortgage red flag and can make a flat genuinely difficult to sell later. Ask what the current ground rent is and whether it escalates, and ask to see the lease terms in writing.

Service charge and major works questions

Ask what the annual service charge is and what it covers. This isnt a nosy question, it's essential. Service charges vary enormously, from a few hundred pounds a year in a small converted house to several thousand in a large managed block. You need to budget for it.

Then ask the harder question. Has there been any major works in the last five years, or is any planned? Buildings need roofs replacing, lifts servicing, cladding inspected. When major works happen, leaseholders often receive a section twenty notice and a bill. That bill can run into tens of thousands of pounds. You have a right to know if one is coming.

Ask whether there is a sinking fund or reserve fund. A well run building puts money aside every year so that when the roof needs replacing, there's money there. A building with no reserve fund means leaseholders get hit with sudden large bills. Ask how much is currently in it.

Finally, ask for the last two years of service charge accounts. A good agent or seller should be able to provide these. If they can't, ask why.

Building safety questions that matter right now

Building safety is not a box ticking exercise anymore. Since the Grenfell Tower fire and the subsequent Building Safety Act 2022, there has been real change in what buyers need to know, particularly for flats in buildings over eleven metres tall.

Ask whether the building has had an EWS1 form completed. This is an external wall system assessment. Not every building needs one, but if yours does and it hasn't been done, some lenders will refuse to mortgage the flat. Ask the agent directly.

Ask about cladding. Has any been removed or replaced? Is any remediation work ongoing or planned? Who is paying for it? Under the current government scheme, developers and building owners are supposed to fund remediation on buildings they were responsible for, but the situation varies building by building.

Also ask when the building was last inspected for fire safety, and whether there is a valid fire risk assessment in place. For buildings with multiple flats, there should be one. Ask whether there are working fire alarms and sprinklers in the communal areas.

Questions about the building and its management

Who manages the building and how long have they been doing it? A good managing agent makes a real difference to day to day life. A bad one means slow repairs, poor communication and money not being spent wisely. You can look up managing agents on the Property Manager database and check whether they belong to a professional body like ARMA or the RICS.

Ask whether the freeholder is a company or an individual. Ask if there is a residents management company, which means the leaseholders themselves have some control over how the building is run. That's generally a good sign.

Ask about any ongoing disputes in the building. Neighbour disputes, disputes with the freeholder, disputes about service charges. You're entitled to ask and the seller is obliged to disclose known issues in the TA6 property information form.

And ask a simple one. How long has the seller lived there, and why are they leaving? You don't always get the full truth, but you can often tell a lot from how someone answers.

Practical questions about the flat itself

Once you've covered the structural and legal stuff, yes, absolutely ask about the flat itself. But ask specific questions rather than just wandering round.

Ask when the boiler was last serviced and ask to see the gas safety certificate. It should be renewed annually by a Gas Safe registered engineer. If it's out of date, that's something to flag.

Ask about the electrics. When was the last electrical installation condition report done? For rental properties this is legally required every five years. For owner occupied flats it isn't mandatory, but a good seller will have one.

Ask about the broadband. Not just whether there is broadband, but what type. Full fibre to the premises is very different from older copper connections. You can check available speeds on Ofcom's checker using the postcode.

Ask about parking, storage, and whether there are any restrictions on letting the flat or having pets. These are often buried in the lease and can catch people out badly.

How to follow up after the viewing

You won't get every answer on the day. That's fine. Write down what you asked and what you were told, then follow up in writing with the estate agent. An email trail is useful if anything turns out to be inaccurate later.

When you instruct a solicitor, make sure they check the lease length, ground rent terms, service charge accounts, and any section twenty notices as a matter of course. A good leasehold solicitor will do this anyway, but it doesn't hurt to flag what you've already found out.

If you're unsure about the building's condition, a RICS surveyor can carry out a full building survey. For a flat in an older or larger block, this is often money very well spent. It won't cover the lease or the legal side, but it will tell you about the physical state of the building and the flat.

Asking good questions at a viewing isn't about being difficult. It's about being the kind of buyer who knows what they're getting into. Sellers and agents respect it, and your future self will thank you.

Common questions

How many years should be left on a lease when I buy a flat?
Most solicitors and mortgage lenders want to see at least eighty years remaining, ideally more. Below eighty years the cost of extending the lease rises significantly due to marriage value rules, and some lenders won't offer a mortgage at all on leases below seventy years. Always check the lease length before you get emotionally attached to a property.
What is a service charge and do I have to pay it?
A service charge is a regular payment made by leaseholders to cover the upkeep of the building and communal areas, things like cleaning, insurance, maintenance and repairs. Yes, you have to pay it. It's a legal obligation under your lease. The amount varies hugely depending on the building, so always ask what the current annual charge is and ask to see recent accounts before you make an offer.
What is an EWS1 form and does my flat need one?
An EWS1 is an external wall system assessment carried out by a qualified professional. It confirms whether the external walls of a building are safe. Not every building needs one, but if your lender requires it and one hasn't been done, you may not be able to get a mortgage on the flat. Ask the estate agent directly whether one exists for the building, and check with your mortgage broker if you're unsure whether your lender requires it.
Can I ask why the seller is moving out?
Absolutely, and you should. You won't always get a completely candid answer, but most people will tell you something honest. If someone has lived there happily for ten years and is moving for work or family reasons, that's reassuring. If they've been there eighteen months and are vague about why they're leaving, it's worth probing a little further. It's not rude to ask. It's sensible.
