Overall verdict
Pros
- Excellent lease terms About 950 years left with no ground rent, so no extension costs and no rising annual charge to worry about.
- Low service charge, run by the residents £2,640 a year is modest for central London, and the company that runs the building is controlled by leaseholders rather than an outside landlord.
- This flat has held a seat on that company before A past owner was one of its directors. Worth asking to take that seat back so you get a say in spending and repairs.
- Inside the congestion charge zone Residents living within the zone can register for the residents' discount, so the daily charge is not a running cost for you.
- Very central, with green space and transport close by Paddington Street Gardens under 100m, Marylebone High Street round the corner, Baker Street and Marylebone stations both walkable.
- Small period block, top floor About 18 flats rather than hundreds. Top floor should mean good light, rooftop views and nobody above you.
Cons
- EPC F, so it cannot be rented out major The legal minimum for letting is E, so you could not let it on completion. From October 2030 the minimum rises to C, and reaching C on a solid-walled top-floor flat with electric heaters is genuinely hard.
- One of the busiest parts of London Marylebone is lovely but heavily trafficked, with delivery bikes and constant footfall nearby.
- Old building, so repair bills get shared out An 1890s block means roof, brickwork and window costs land on leaseholders eventually. A low service charge can mean a thin savings pot and occasional large bills.
- Small flat 538 sq ft, the smallest configuration in the block, which limits the buyer and tenant pool.
- Likely to run hot in summer A top floor with poor insulation and a flat roof above tends to overheat. Worth checking the roof insulation and the aspect.
- Parking will be difficult No allocated space, and street parking here is tightly controlled by the council.
The bones of this one are genuinely good: a scarce Victorian block in a location that will always be wanted, a lease with roughly 950 years left and nothing to pay on ground rent, a modest service charge, and a building run by the people who live in it. The catch is the energy rating. At F you cannot legally let it, and getting it up to the standard required from 2030 will be slow and expensive on a solid-walled top floor. That is the main thing to price in, and it is also your strongest argument for paying less than the £600,000 asked. Buy this for the location and the lease over a long hold, not for quick growth.
Buyer's due-diligence checklist
Building costs and ownership
Three years of service charge accounts, plus the savings pot
The single most useful document. A £2,640 charge is attractive, but only if the building has been putting money aside for big jobs. Ask for the reserve fund balance and the current budget. If there is little saved, expect one-off bills instead.
Any major works already planned
Ask for the last two or three years of meeting minutes and any formal notices of major works. Roof, brickwork, windows and drains are the usual culprits in a block this age, and the roof matters most to you as the top-floor flat.
The lease itself, and your seat on the company
Confirm the 950 years and zero ground rent in writing, along with who repairs what. Check for any restriction on letting the flat out or short-letting it. Then ask how to become a director of the residents' company, since this flat has held that role before.
The flat itself
Get a retrofit quote, twice
One price to reach E (the level needed to let it at all), and a separate price to reach C for 2030. Roof insulation, better storage heaters and lighting are the likely wins. Internal wall insulation works but eats floor space and needs permission.
Check the aspect and summer heat
Confirm which way the windows face. Visit on a warm afternoon if you can, since a top floor under a poorly insulated flat roof gets hot.
Is there a lift?
Fourth floor with no lift affects both rental appeal and resale. Confirm it, and check the condition of the communal areas while you are there.
Around the building
Noise, at different times
Listen with the windows open and closed, in the morning, late evening and on a weekend night. Traffic, sirens and restaurant noise are the things to test.
Nearby building plans
There has been development activity near the block, and residents previously objected over light and outlook. Ask what is proposed or approved behind and opposite, particularly at your floor level.
Parking, if you need it
No space comes with the flat. Check the council's resident permit rules and cost for this street before assuming you can park.

The flat
Lease ~950 yrs
No ground rent to pay. In practice this removes the two biggest leasehold headaches: extension costs and a charge that climbs over time.
Service charge £2,640/yr
About £220 a month, which is low for central London. There is no porter, gym or car park, so you are paying for the building itself.
Council tax
Band E, Westminster.
Energy rating F
Assessed December 2025. Solid brick walls with no insulation, a flat roof with very little, electric storage heaters and immersion hot water. Running costs are estimated near £2,400 a year. The assessor rates the ceiling as C.
Size and position
538 sq ft (about 49 to 50 m²), one bedroom, fourth and top floor, with rooftop views and good daylight per the agent.
Who runs the building
A residents' management company that has existed since 1976, with leaseholders as directors alongside a professional secretary. No outside landlord taking ground rent or insurance commission.

Position on the street
This street is a quieter residential turning, seconds from Marylebone High Street without being on it. A good combination.
Noise busy area
The street itself is calm, but this is one of the busiest parts of London. Expect traffic, delivery riders and footfall close by.
Crime
Lower on this street than the wider Marylebone average, though theft and antisocial behaviour are common across the commercial parts of the area.
Market
The block is down roughly 16% over ten years while rents have risen. Prime central London has been flat for years, so treat this as income and location rather than growth.
Other
Flood risk negligible, ultrafast broadband available.
Verify before you offer
1
The energy rating
At F you cannot let it. Get quotes to reach E, then C, and use the number as a negotiating lever.
2
Service charge accounts and savings pot
Three years of accounts plus the reserve balance. A low charge with nothing saved means bills later.
3
Roof and planned works
You are on the top floor, so the roof is your risk. Ask for meeting minutes and any major works notices.
4
Lift, aspect and nearby plans
Confirm whether there is a lift, which way the flat faces, and what is being built nearby.
Where the price sits
At £600,000 you are paying about £1,115 per sq ft. Another unit in the same block sold for £596,000 in January 2025 and was materially larger at roughly 602 sq ft, which works out near £990 per sq ft. That is a fair question to put to the agent. The asking price has already come down £50,000 and the flat has been on the market a while, so there is room to talk. Around £575,000 to £585,000 looks like better value, and less again if the energy work turns out to be costly.
The lease, the absence of ground rent, the low service charge and a building run by its residents make an unusually good combination. The energy rating is the thing standing in the way.
Summary of the research
Parking
No space comes with the flat, and the surrounding streets are tightly controlled with resident permit bays, pay-by-phone sections and loading restrictions. If a car matters to you, treat this as a real drawback. If it does not, the transport here is about as good as London gets.
