You cannot visit Syon House on a Saturday. Or a Wednesday, Thursday or Friday.
Checked on 6 October 2026, the house and the gardens both open on Sunday, Monday and Tuesday only. Wednesday to Saturday, everything is closed.
For a stately home in west London with a free car park, being shut on the one day most people are free is the single most important thing to know about it.
Sunday is the only day you can walk round on your own
The three open days are not the same product.
Sunday: self-guided entry, 10.30am to 3.30pm, last entry 2.30pm.
Monday and Tuesday: guided tours of the house only, up to 90 minutes. First tour 10.30am, last tour 2.00pm.
So if you want to wander at your own pace, it has to be a Sunday. If you want the guided version with the history, it has to be a Monday or a Tuesday, and the last tour leaves at two.
The gardens and Great Conservatory run 10.30am to 3.30pm on all three days, last entry 2.30pm, and can be visited without the house.
The gardens alone cost £7
Less than half the house price, and worth knowing if the Great Conservatory is what you came for.
Gardens and Great Conservatory only, online then on the door:
Adult £7.00 / £8.00. Concession, meaning over 60s and students, £5.50 / £6.50. Child 5 to 16 £3.50 / £4.50. Family, two adults and up to three children, £20.50 / £21.50.
House, gardens and conservatory:
Adult £16.50 / £17.50. Concession £15.00 / £16.00. Child £9.50 / £10.50. Family £48.00 / £49.00.
Booking online saves £1 a head on every ticket type. On a family ticket that is £1 total, not £1 each, so the saving is smallest exactly where the spend is largest.
The family ticket itself is the real saving: five people paying individually on the door is £66.50 against £49.
The season ends in October
“Our open season runs from March to October.”
Eight months, three days a week. Which works out at roughly 100 opening days a year, and makes Syon one of the hardest big houses in London to actually get into.
Season tickets run to the end of the season in the year of purchase, give 10 per cent off gifts in the Visitor Centre, and are not valid for special events or outside normal opening days and times. They are bought at the Visitor Centre or by email rather than online.
The house is not wheelchair accessible, and they say so
Direct, and the detail is useful.
“Due to the historic nature of the building we regret that we are unable to offer access for wheelchair users or motorised scooters into Syon House.”
What that means in practice: eight stone steps to the Great Hall, a few stairs on the principal floor, and a large staircase up to the bedrooms.
The grounds are a separate question and only partly better: cobblestones, flagstones, grass, gravel and wood, uneven and steep in places with a few steps.
So the gardens-only ticket is the realistic option for anyone with mobility needs, and even that is mixed terrain.
Groups of 25 get split in two
Worth planning around if you are organising a coach.
“Groups of over 25 will be split into two beginning their tours fifteen minutes apart.”
Advance booking is essential for any group visiting the house. Minimum 15 people at £16.50 adult and £15.00 concession, and over 25 earns one free ticket.
Private guided tours run on Mondays or Tuesdays and can be tailored. The options run from a 30 minute “Syon Sprint” to the full 90 minute tour, or anywhere in between. Garden tours are available on request by email.
One caveat the house states plainly: all tours involve standing and walking.
Free parking and 14 fast chargers
Unusual for a London attraction and a genuine reason to drive here rather than to most of them.
“The large free car park is available for those visiting Syon Park or one of the businesses on site.” Parking is at the owner’s risk.
Electric charging is in the car park at the InstaVolt Superhub: 14 charging points at speeds up to 160kW.
That is a serious charging stop, not a token pair of posts, and it is free to park while you use it.
