Every year families from the Gulf come to London for treatment and stay for weeks in serviced apartments at £400 to £900 a night. Some decide to buy. This guide maps Harley Street and the private hospitals, prices the flats within a walk of each, explains the 11-month medical visitor visa at £234, and sets out the tax, the running costs and the letting that make a bought flat pay between visits.
Areas
Harley Street and the private hospitals: buying a London base for medical visits
London's private hospital districts and where to buy near them
London’s private hospitals sit in two clusters: Harley Street and the streets around it in Marylebone, and a southern group in Belgravia, Chelsea and Kensington, with the Wellington in St John’s Wood to the north. A two-bedroom flat within a walk of Harley Street costs £1.3 million to £2.8 million in 2026. A family that visits for treatment for more than eight to ten weeks a year, and will let the flat in between, usually comes out ahead of serviced apartments within seven to ten years.
Harley Street is a Georgian street in Marylebone that has housed doctors since the nineteenth century. The Howard de Walden Estate, which owns most of the district, has kept it medical: about 3,000 practitioners work on Harley Street, Wimpole Street, Devonshire Place and the streets between Marylebone High Street and Portland Place. The London Clinic, King Edward VII’s Hospital, the Harley Street Clinic, the Princess Grace and the Portland are all within a few hundred metres of one another.
Private hospitals in Belgravia, Chelsea, Kensington and St John's Wood
The second cluster is a mile south. Cleveland Clinic London opened at 33 Grosvenor Place in Belgravia in 2022, the largest new private hospital in the city in a generation. The Lister is on Chelsea Bridge Road, the Cromwell on Cromwell Road in Kensington, and the Wellington in St John’s Wood is the largest independent hospital in the UK. Each sits in a district our guides already cover: Knightsbridge and Belgravia, Kensington and Chelsea and St John’s Wood.
Why Gulf families come to London for medical treatment
Gulf governments and families have sent patients to London for fifty years: the embassies’ medical offices are in Marylebone and Belgravia, the consultants have Arabic-speaking secretaries, and the Regent’s Park mosque and the Edgware Road restaurants are a short walk from Harley Street. The Saudi, Kuwaiti and Emirati health offices sponsor thousands of patients a year, each with family who need somewhere to stay for the weeks of treatment and the months of follow-up.
Renting, serviced apartment or buying for medical visits
A family that comes to London for treatment faces three choices: a hotel or serviced apartment paid by the night, a long let of six months or more, or a purchase. The arithmetic depends on how many nights a year the family is in London and whether it will let the flat when it is not. A family in London for a month a year should rent. A family here for three months a year, with follow-up visits and children at school or university in London, is a buyer.
The purchase is a lock-up-and-leave flat with a porter, a lift and a short walk to the hospital, let to a medical or corporate tenant between visits. The cost of buying is set out in our guide to the full cost of a London flat; the taxes that follow are in the sections below.
Which London hospital and which streets to buy near
The flat should be a walk from the hospital, not a drive: a patient in the weeks after surgery, a parent visiting a child on a ward twice a day, a family that does not want a car in central London. The table matches each hospital to the streets within ten minutes on foot.

Why Marylebone is the default area for a medical base
Five of the hospitals are in Marylebone and the consultants’ rooms are there whichever hospital admits the patient, so a family that does not yet know which hospital it will use should buy in Marylebone. Our Marylebone guide covers the district street by street. Belgravia suits a family already under Cleveland Clinic’s care; St John’s Wood suits one that also wants the mosque and the American School within a walk.
Flat prices near Harley Street and other hospital districts
The flats a medical visitor wants are the lateral ones in porter blocks with lifts, which carry a premium over walk-up conversions. The ranges below are for Marylebone; Belgravia is 30 to 50 per cent higher per square foot and St John’s Wood 10 to 20 per cent lower.
Indicative prices within a walk of Harley Street, autumn 2026
| Property | Price | Monthly rent when let |

Gross yields are 3 to 4 per cent, half a point better than Knightsbridge, and the tenant base includes the hospitals’ own consultants and visiting fellows, which is why voids near Harley Street are short. Our yields guide sets the figure against the rest of London.
UK visa rules for patients and families visiting for treatment
Owning a flat gives no right to stay, as our guide on property and residency explains. A patient and the family members with them come as visitors, and the rules for a medical visit are specific enough to set out.
The Standard Visitor visa for private medical treatment
A Standard Visitor visa costs £135 and allows a stay of up to six months. A patient whose treatment will last longer applies for the private medical treatment option, which lasts up to 11 months and costs £234. Once in the UK, a visitor can apply to extend by a further six months for £1,172, with no limit on the number of extensions while treatment continues. Gulf nationals who normally use the Electronic Travel Authorisation need the visa for the 11-month option.
The evidence for the medical option is a letter from the consultant giving the condition, the estimated cost and duration of treatment and where it will take place; proof the treatment is arranged and funded; and proof the patient will leave when it ends. The family’s side:
- Consultant’s letter: condition, estimated cost, likely duration, the hospital or clinic.
- Proof of arrangements: the hospital’s admission or appointment confirmation.
- Proof of funds: bank statements or a sponsor’s letter from the embassy health office covering treatment and living costs.
- Accommodation: the title or tenancy of the London flat, which answers the question of where the family will stay.
- Intention to leave: ties to the home country, return tickets or a return plan.
- Accompanying family: each applies as a Standard Visitor with the same evidence; a flat owned by the family supports every application.
The UK tax residence risk for long medical stays
A patient who spends 183 days or more in the UK in a tax year, or who has a UK home and spends 91 days here with only limited ties abroad, can become UK tax resident under the statutory residence test. A long course of treatment with family in a bought flat is exactly how it happens. Our guide to tax residence and summers in London explains the day counts; count the medical days with the summer days.
Buying a London flat versus serviced apartments for medical visits
A serviced two-bedroom apartment in Marylebone costs £400 to £900 a night in 2026, so a family in London ten weeks a year spends £28,000 to £63,000 on accommodation. A bought two-bedroom flat at £2 million carries £293,750 of stamp duty for a non-resident buyer owning another home, as the next section shows, plus £8,000 to £15,000 a year in service charge, council tax and insurance. Let for the other forty weeks at £4,500 a month it earns about £40,000 gross.
Break-even point for buying instead of renting for treatment
On those figures the bought flat’s running costs are covered by the letting, and the serviced-apartment spend is saved, so the purchase costs of roughly £330,000 (stamp duty, fees and furnishing) are recovered within seven to ten years before any price growth. A family here four weeks a year does not reach that point for twenty years and should rent. A family that will not let the flat, because it wants it kept ready, pays the running costs itself and should treat the purchase as a convenience, not an investment.
Tax and running costs
The purchase taxes are the same as for any overseas buyer. On a £2 million flat bought by a non-resident who owns a home abroad, stamp duty is the standard bands plus the 5 per cent additional-dwelling surcharge and the 2 per cent non-resident surcharge, £293,750 in all. Our stamp duty guide shows the bands; a buyer who sells the family’s main home abroad within three years may claim part back, as our refunds guide explains.
Buying a medical-visit flat through a company: tax costs
Families sometimes buy a medical-visit flat through a company for privacy. A company pays the 17 per cent flat rate (19 per cent if non-resident) on a flat over £500,000 unless it lets the flat commercially, and the Annual Tax on Enveloped Dwellings each year while the family uses it. Our guide to company or own name runs the numbers; for a flat the family will occupy, own names almost always win.
Council tax and service charge on a Marylebone flat
Westminster council tax on a Band G or H flat runs to a few thousand pounds a year, and a second-home premium may apply where the flat is furnished and nobody’s main home; our council tax premium guide gives each borough’s position. Service charges in Marylebone’s mansion blocks are £6 to £12 per square foot; the new schemes charge £15 to £25. Our guide on running a London second home itemises the rest.
Letting your London flat between hospital visits under the Renters' Rights Act
The flat pays for itself only if it is let, and the tenancy must end when the family needs it. Since 1 May 2026 every tenancy is periodic under the Renters’ Rights Act, a tenant gives two months’ notice and a landlord needs a ground; there is no fixed term to time against the next visit. Our guide to the Renters’ Rights Act for overseas landlords sets out the grounds.
Three ways to keep the flat available for your visits
The first is to let to the hospitals’ own market: visiting consultants, fellows and families of other patients, on short company lets through an agent who specialises in Harley Street, where a few months’ tenancy is normal. The second is a corporate let to a tenant who accepts that the owner returns each summer, written into the tenancy’s terms. The third is not to let at all and accept the cost. Short lets through Airbnb are capped at 90 nights a year in London and need planning permission beyond that, as our short-lets guide explains.
Whichever route, rent paid to an overseas owner has tax deducted at source unless HMRC approves the owner under the Non-Resident Landlord Scheme; our NRL guide explains the form. A letting agent chosen from abroad who knows the medical market is the single most useful appointment.
Our view on buying a flat near Harley Street
A family that comes to London for treatment more than eight weeks a year, with follow-up visits and relatives who come too, should buy a two- or three-bedroom lateral flat in a porter block within ten minutes’ walk of Harley Street, in the family’s own names, and let it between visits to the medical and corporate market through a Marylebone agent. On those terms the flat covers its costs, saves the serviced-apartment bills, and holds its value in the steadiest district in prime central London.
A family whose treatment is a single episode should rent a serviced apartment and keep its money liquid. A family deciding between the two should count its London nights honestly over the last three years, and we will run the arithmetic on the flats we would buy.

Frequently Asked
Questions about buying near Harley Street
Yes, as a visitor. Owning a flat gives no immigration status, but it is good evidence of accommodation on a Standard Visitor application. The six-month visa costs £135; the private medical treatment option allows up to 11 months for £234, with six-month extensions at £1,172 while treatment continues.
Marylebone. The London Clinic, King Edward VII’s, the Harley Street Clinic, the Princess Grace and the Portland are all within a few hundred metres of Harley Street, and the consultants’ rooms are there whichever hospital admits the patient. Belgravia serves Cleveland Clinic London; St John’s Wood serves the Wellington.
In autumn 2026 a one-bedroom flat in a porter block is £850,000 to £1.3 million, a two-bedroom £1.3 million to £2.8 million and a three-bedroom lateral flat £2.8 million to £7 million, at £1,500 to £2,400 per square foot. The new schemes charge £2,800 to £4,000 per square foot.
A non-resident buyer who owns a home abroad pays the standard bands plus 5 per cent and 2 per cent surcharges: £293,750 on a £2 million flat. Part of the 5 per cent can be reclaimed if the family’s main home abroad is sold within three years of completion.
It can. 183 days in a tax year makes anyone resident, and a UK home plus 91 days with few ties abroad can do the same. Count the treatment days with the summer days and take advice before the total approaches the thresholds.
Only with care. Tenancies are periodic since 1 May 2026 and a landlord needs a ground to end one. Short company lets to the medical market, or a corporate let with the owner’s return written in, are the practical routes. Airbnb is capped at 90 nights a year.
For a family in London four weeks a year, yes. At £400 to £900 a night, ten weeks costs £28,000 to £63,000, which is the point where a let flat’s economics overtake renting. Below eight weeks a year, rent; above ten, buy.
Rarely. A company pays 17 per cent stamp duty (19 per cent if non-resident) on a flat over £500,000 it does not let commercially, and the Annual Tax on Enveloped Dwellings each year the family uses it. Own names, with a will, are the usual answer.
