Studios are the one property type where a single number decides everything. The nationally described space standard is 37 square metres with a shower room, or 39 with a bathroom. Space standards only became mandatory for permitted development conversions in 2020 — which means a great deal of smaller, darker office-to-residential stock built before that still trades, and it behaves very differently on a mortgage application and on resale.
Thirty-seven square metres with a shower room, thirty-nine with a bathroom. We ask for the gross internal area rather than accepting ‘compact’, because below the standard the property behaves differently on finance and on resale.
Many lenders apply a minimum floor area and criteria on layout — particularly on ex-local-authority stock and on units without a separate kitchen. A cash-priced studio and a mortgageable studio are two different assets.
Apportionment is by area, but a studio does not let for a proportionate fraction of a two-bedroom rent. The service charge therefore takes a much larger bite out of a studio’s income, and that is where studio yields quietly disappoint.
Our fee is paid by the seller or the landlord. No fee to you, and none to a tenant either — tenant fees have been banned since 2019.
To live in, to let, or to hold. It changes everything: a 28 square metre studio can be a perfectly good home bought with cash and a poor investment bought with a mortgage.
Gross internal floor area, ceiling height, natural light, whether it meets the space standard, the service charge and ground rent, and the likely lender position — before you view.
If the area, the light or the lease means the studio will be hard to finance and harder to sell, you will hear that from us before you have paid for a survey.
The nationally described space standard sets a minimum gross internal area of 37 square metres for a one-bedroom, one-person dwelling with a shower room, or 39 square metres where there is a bathroom. In London the ceiling height minimum is 2.5 metres against the national 2.3 metres over 75 per cent of the floor area, and best-practice guidance published in June 2023 recommends 41 to 43 square metres rather than the minimum.
The point that matters for a buyer is the date. Space standards only became mandatory for permitted development conversions in 2020. A very large quantity of office-to-residential stock was created before that under the earlier permitted development rights, some of it well below 37 square metres, some with poor or no natural light, and much of it in buildings that were never designed to be lived in.
Lenders apply their own criteria on studios, and they vary. Common constraints include a minimum gross internal floor area, a requirement for a separate or at least a partitioned kitchen, caution on ex-local-authority blocks above a certain height, and caution on former commercial buildings converted under permitted development.
The practical consequence is that a cash-priced studio and a mortgageable studio are two different assets at the same address. If you are buying with finance, get a decision in principle against the specific property rather than a generic one, and do it before you offer. If you are buying with cash, understand that your eventual buyer may not be able to, which narrows your exit.
Service charge apportionment is normally by floor area, which sounds proportionate and is not. A studio at roughly 40 per cent of a two-bedroom flat’s area does not let for 40 per cent of the two-bedroom rent — it lets for rather more, because a tenant is paying for a location and a front door as much as for square metres.
So the studio pays a smaller service charge in absolute terms but a much larger one relative to its income. On a low-value studio in a building with a concierge, lifts and communal plant, the charge can consume a strikingly large share of the rent, and it is the single most common reason a studio yield that looked strong on paper disappoints in practice. Model it against the rent, not against the price.
Your protections changed on 1 May 2026 and they apply to a studio exactly as to anything else: no bidding above the advertised rent, no more than one month’s rent in advance, periodic tenancies with two months’ notice, annual rent increases with two months’ notice, and no letting agent fees.
The studio-specific thing to check is what the rent actually includes. In converted buildings, heating and hot water are frequently communal and billed through the service charge or as a separate heat network charge rather than by a meter you control. Ask before you sign, because a rent that looks competitive can carry a fixed heat charge you cannot reduce by using less.
The nationally described space standard is 37 square metres of gross internal area with a shower room, or 39 with a bathroom. London adds a 2.5 metre ceiling height minimum over 75 per cent of the floor area, and June 2023 best-practice guidance recommends 41 to 43 square metres. Space standards became mandatory for permitted development conversions in 2020, so stock created before then can be smaller and still be lawful.
Sometimes, and it depends on the lender and the specific property. Common constraints are a minimum floor area, a requirement for a separated kitchen, and caution on ex-local-authority high-rise or on former commercial buildings converted under permitted development. Get a decision in principle against the actual address before you offer — a generic one tells you nothing useful about a studio.
They can be, and the yield is often overstated because the service charge is modelled against the price rather than against the rent. A studio pays a smaller charge in absolute terms than a two-bedroom flat but a much larger one relative to its income, because rents do not scale down with floor area the way service charges do. Model it against the rent, and factor in that a non-mortgageable studio has a narrower resale market.
Nothing inherently, and many are good. But space standards only became mandatory for permitted development in 2020, so earlier conversions can be below 37 square metres, can have limited natural light, and sit in buildings never designed as homes. They are lawful and they trade — they are simply harder to finance and slower to sell, and the price should reflect that rather than matching a compliant unit down the road.
No. Our fee comes from the seller or the landlord, and tenant fees have been banned in England since 2019 in any event. What it buys you is somebody asking for the floor area in writing before you view.
