Second viewing of a flat, what to check before you make an offer
Your first viewing was about falling in love. Your second is about due diligence. Here's exactly what to look at before you commit.

Why the second viewing is the one that really counts
The first viewing is emotional. You're clocking the kitchen worktops, imagining your sofa by the window, working out whether the spare room fits a bed. That's fine. That's human. But the second viewing is where you put your sensible hat on and look at the things that could cost you thousands, or make your life a misery, before you've even unpacked a box.
Flats are different from houses in one important way. You're not just buying the flat itself. You're buying into a building, a management structure, and a set of neighbours. What happens in the communal areas, on the roof, and in the bin store affects you directly, even if none of it sits inside your front door. So use the second visit to look at all of it.
Book it at a different time of day than your first visit if you can. A flat that felt bright and quiet on a Tuesday morning might feel very different on a Friday evening. That contrast alone can tell you a lot.
Start outside and look up
Before you even ring the buzzer, stand back and look at the building. What's the roof like? On a flat roof, look for obvious sagging, pooling marks, or patches of repair. On a pitched roof, check for missing or slipped tiles and whether the guttering looks intact. You're not a surveyor, and you won't catch everything, but you're looking for signs of neglect. A building where the roof has been ignored is a building where the service charge probably hasn't been spent wisely.
Look at the windows on the outside too. Are they all the same style, or has the building got a patchwork of different frames because individual leaseholders have replaced their own over the years? That can be a sign of a poorly managed building where nobody's enforcing the lease properly. Check whether the window frames look rotten or warped, and whether you can see any misting between double glazed panes from the outside.
While you're out there, look at the main entrance. Is it secure? Does the door close properly behind you? A propped-open communal door is a security issue and sometimes a sign that the entry system is broken and nobody's fixed it.
Walk every inch of the communal areas
This is the bit most buyers rush past. Don't. The communal areas are managed and maintained by whoever runs the building, and their condition tells you everything about how that building is run.
Walk the corridors and stairwells. Are the lights working? Is the carpet clean and in decent repair, or is it threadbare and stained? Is there a smell of damp anywhere? Damp in communal areas often means a roof or drainage problem that's already happening and may already be expensive to fix.
Look at the walls and ceilings for water stains, even old ones. A brown tide mark on a ceiling doesn't go away by itself. It means water got in somewhere, and you want to know whether it's been properly fixed or just painted over.
If there's a lift, check whether it looks maintained and whether there's a current inspection certificate displayed. Most local authorities require these to be visible. A lift that's out of service or clearly neglected is a cost waiting to happen, and that cost will come through the service charge.
Check the post room and bin store while you're at it. We'll come back to both of those in more detail, but on your walk-through, just note whether they're tidy and whether they smell. A building where people leave rubbish in the corridor or let post pile up for weeks is giving you information about the culture of the place.
Inside the flat, go slow and go methodical
You've seen the flat once. Now look at the things you probably glossed over. Open every window and check the frames for rot, condensation marks, and whether the mechanisms actually work. Look at the corners of every room, especially at ceiling level, for dark spots that might be mould. Mould in corners often means poor ventilation or cold bridging rather than a leak, but either way you want to know about it.
Run the taps. Check the water pressure. Flush the loo. Turn on the shower and see how long it takes to get hot. These are basic things that a surveyor will check, but there's no reason you can't do it yourself first.
Look at the boiler. How old is it? Is there a service sticker on it? A boiler that hasn't been serviced in years isn't necessarily about to fail, but it's a negotiating point and a future cost.
Check the storage. Not just whether there's enough of it, but whether it smells damp or musty. Airing cupboards and built-in wardrobes on external walls can hide a lot of problems.
Ask the agent or the seller directly what the service charge is and what it covers. Ask whether there's a reserve fund and roughly what's in it. Ask whether any major works are planned or have been discussed. You won't always get a straight answer, but asking the question signals that you're paying attention, and sometimes you'll learn something useful.
Listen for noise and think about the lease
Noise is one of the most common reasons people regret buying a flat, and it's one of the hardest things to assess on a quick viewing. On your second visit, spend a few minutes just standing still and listening. Can you hear the flat above? The flat next door? Traffic? A commercial kitchen or a pub below? If the building is near a main road, stand at the windows and see how much comes through when they're closed.
Ask the seller how the building is constructed. Concrete frame buildings tend to transmit less noise between floors than timber frame ones. That's a generalisation and your surveyor will give you a proper view, but it's worth asking.
While you're thinking about the building's structure, ask to see a copy of the lease if you haven't already. You don't need to read the whole thing on the spot, but check two things. First, how many years are left on it. Lenders commonly want around seventy to eighty five years remaining when you apply for a mortgage, and each lender sets its own minimum, so check with your mortgage broker. If the lease has fewer than eighty years left, extending it will cost more because something called marriage value applies, adding to the premium you'd pay. The rule that you had to own a flat for two years before you could apply for a statutory lease extension was abolished from thirty first January twenty twenty five, so you can start the process sooner than used to be possible. But always confirm the current position with your solicitor, because this area of law has been changing and may change again.
Second, check what the ground rent is. Any new long residential lease granted from thirtieth June twenty twenty two must carry a peppercorn ground rent, meaning effectively nothing. But older leases can have ground rents that escalate, and some of those can cause problems with mortgage lenders. Your solicitor will flag this, but it's worth knowing about before you get too attached.
The bin store and the post room
These two things sound mundane. They are not. They're the clearest possible signal of how a building actually functions day to day.
A good bin store is clean, organised, and has clearly labelled recycling and general waste. The bins are put out and brought back in on time. There's no overflow of rubbish sitting on the floor. If the bin store is chaotic and smells terrible, it usually means one of two things. Either the management company isn't on top of it, or the residents don't care. Neither is great.
The post room matters more than you might think, especially if you're going to be out during the day. Is there a secure parcel locker or a dedicated parcel shelf? Is there a system for recorded deliveries, or does everything just get left in a pile? A building with no real system for post and parcels is a minor daily frustration that adds up fast.
While you're in these areas, look at the noticeboards if there are any. Management companies and residents' associations often post notices about upcoming works, AGM dates, or complaints. A noticeboard full of passive aggressive notes about noise or bin misuse tells you something about the community. A noticeboard with a recent AGM summary and a clear schedule of planned maintenance tells you something much better.
Before you leave, ask these questions out loud
Don't rely on the agent to volunteer information. Ask directly and listen carefully to how they answer, not just what they say.
Ask who manages the building and whether there's a residents' management company or a third party managing agent. Ask when the building was last redecorated externally. Ask whether there have been any disputes between leaseholders and the freeholder. Ask whether the seller has had any issues with the flat that they've had to report to the managing agent.
You can also do a basic check yourself before you make an offer. HM Land Registry charges seven pounds to download a title register for a property on gov.uk. That register will confirm whether the property is leasehold or freehold, who the registered owner is, and whether there are any charges or restrictions on the title. It won't tell you everything, but it's seven pounds well spent and takes about five minutes.
None of this replaces a proper survey. A RICS surveyor will go further than you can on a viewing, and for a flat you should seriously consider a full building survey rather than just a homebuyer report, especially if the building is older or the lease has any complications. But going into that survey having already asked the right questions means you'll get more out of it, and you'll be much harder to catch off guard.
Common questions
- How long should a second viewing of a flat take?
- Give yourself at least an hour, ideally more. You want time to walk the communal areas properly, sit quietly and listen for noise, check every room methodically, and ask questions without feeling rushed. If the agent is pushing you to wrap up quickly, that's worth noticing.
- Can I ask to see the service charge accounts before making an offer?
- You can ask, and a seller who's confident about the building's management should be happy to share them. You won't always get them at this stage, but your solicitor will request them as part of the conveyancing process. If the accounts show a very low reserve fund or a history of large unexpected bills, that's important information before you exchange contracts.
- Does the two year rule still apply before I can extend my lease?
- No. The requirement to own a flat for two years before applying for a statutory lease extension was abolished from thirty first January twenty twenty five. That said, this area of law has been changing, so confirm the current position with your solicitor before taking any steps.
- What's the quickest way to check if a flat is leasehold before a second viewing?
- Go to the HM Land Registry website. The free property search will tell you whether a property is registered as freehold or leasehold and give you its title number. If you want the full title register with details of the registered owner and any charges, that costs seven pounds to download.
