| A vision of 'Managed Decline': What happens when the £1.5 million-a-week patch-up finally fails. |
Remember that nursery rhyme/song 'London Bridge is Falling Down'? Here's a new version:
| Parl-i-ment is falling down, Falling down, falling down. Westminster Palace is falling down, My fair Taxpayer. |
Westminster Palace where the UK Parliament is held really is in danger of collapse. It currently costs £1.5 million a week to stop falling masonry, fires breaking out and it flooding with sewage. There are plans for major repairs but the costs are frightening - up to £39 billion to stabilise things. |
| Build it up with iron and steel, Iron and steel, iron and steel. But rust will make the structure reel, My fair Taxpayer. |
Much of the roof is made from that Victorian wonder material - cast iron. It's rusting and as it does so expands and leaks. There are 250 miles of ancient copper wire with crumbling insulation that needs replacement. It runs alongside Victorian plumbing for heating, water and sewage. The plumbing leaks dangerously onto the wiring. In winter the House of Lords have sat wearing coats because of failed heating. |
| Build it up with Anston stone, Anston stone, Anston stone. It crumbles to the very bone, My fair Taxpayer. |
The original building was made from Anston limestone. A material used because it was cheap. Unfortunately it is not a durable limestone and even before the building was completed, it was starting to crumble in the acid air of the time. It's still being eaten away. |
| Patch it up with plastic chutes, Plastic chutes, plastic chutes. While asbestos fills the air and nooks, My fair Taxpayer. |
In many places plastic guttering has been installed to prevent water/sewage from dripping onto dangerous wires and circuit boards. A temporary solution but made far more expensive by the presence of asbestos throughout the building. A minor job like fixing a leaky tap often requires a full hazardous-materials team, turning a 30-minute repair into a multi-day, multi-thousand-pound operation. |
| Build it up with silver and gold, Silver and gold, silver and gold. Forty billion is a price too bold, My fair Taxpayer. |
The costs involved are horrendous. Maintenance teams are currently handling roughly 2,900 reactive tasks every month. That is nearly 100 "something just broke" incidents every single day, ranging from falling masonry to sewage leaks. We are spending £1,500,000 a week to stop the building from falling apart. There are two long term solutions proposed but the most favoured one will cost £40 billion. |
The "Final Vote" on the possible options isn't expected until 2030, meaning another £312 million (at £1.5m a week) will be spent on temporary patches before a single permanent brick is even laid.
Let's look at the problems in more detail.
The Roof
The Rusted Struts: The cast iron sections are held up by support struts that have been rusting for over 160 years. In many places, the iron has expanded (oxidized), causing the tiles to crack or shift.
Active Leaks: Water ingress is a constant battle. In the last month alone (February 2026), major leaks were reported in the Colonnade and near the House of Commons ceiling.
The "Waterfall" Incident: A few years ago, business in the Commons had to be suspended because water was literally pouring through the ceiling onto the benches—that issue hasn't been "fixed," only "patched." This isn't just a plumbing issue; it's a constitutional one. When the roof leaks, democracy stops.
The rest of the roof is so fragile that engineers are hesitant to even walk on certain sections for fear of triggering a collapse into the chambers below.
There's a £3 billion Phase One works starting this year (2026) including a specific focus on the Victoria Tower roof (the opposite end to Big Ben) and internal structure. The Victoria Tower is suffering from severe masonry decay at the roofline. Cast iron supports have rusted and expanded making the stone unstable. Chunks of stone have been known to fall from the ornamental "crown" of the tower, making the area below a safety hazard.
The wiring
There is a maze of wiring throughout the Palace most of it long past its life expectancy. Rubber and cotton insulation has decayed to the point that, if it is moved even slightly, it crumbles to dust and no longer insulates causing short circuits with the danger of fire. Old wiring which is no longer used has been left in place to avoid disturbing newer but still dangerous wiring. Since 2016, there have been 36 fire incidents, The risk of fire is so great that, because the fire alarm system is so unreliable and the wiring so fragile, we the taxpayers pay for a team of 28 full-time fire officers to maintain a 24-hour watch. With seven officers on shift at all times, they are effectively 'human smoke detectors' patrolling 1,100 rooms to catch an inferno before it starts.
The Plumbing
- As of March 2026, officials have confirmed that the sewerage and heating systems are in a state of near-constant failure.
A sewage ejector system was installed in 1888. It uses compressed air to "shunt" waste through the building. When it fails (which it does frequently), it doesn't just stop working; it can lead to "significant problems with the sewerage system" that have recently forced the closure of multiple toilet blocks across the building
Parts are long since obsolete and can't simply be replaced with modern fittings
Several toilets are currently permanently closed not just because of leaks, but because they are located in areas with crumbly concrete, making it too dangerous for plumbers to even enter the rooms to fix the pipes.
There are over 14 miles of water and waste pipework snaking through the basement and walls. Leaks are common and especially dangerous when they are near ancient wiring. In some places plastic guttering has been installed to catch leaks which can't be conveniently fixed.
Much of the Palace is still heated by high-pressure Victorian steam pipes for which spare parts are unavailable. Each fitting replaced must be forged from scratch.
The asbestos
- Asbestos is present in more than 2,500 locations. Because it’s so widespread, even a minor job like fixing a leaky tap often requires a full hazardous-materials team, turning a 30-minute repair into a multi-day, multi-thousand-pound operation. Almost every mile of the plumbing is wrapped in asbestos lagging. To fix a one-inch leak, a team must:
Build a sealed plastic tent.
Send in specialists in hazmat suits.
Slowly strip the lagging.
Only then can a plumber touch the pipe.
This turns a £50 plumbing job into a £10,000 hazardous waste operation, which is a major reason why the weekly maintenance bill has hit £1.5 million.
So what are the options?
| Feature | Option 1: Full Decant | Option 2: Staged Works (EMI+ |
| Strategy | Everyone moves out (MPs and Lords). | Work done in stages; Parliament stays. |
| Duration | 19 – 24 years | 38 – 61 years |
| Estimated Cost | Up to £15.6 billion | Up to £39.2 billion |
| Key Benefit | Faster, cheaper, and safer. | Avoids the "political optics" of leaving. |
| Key Risk | Significant disruption to tradition. | Massive cost; extreme fire risk during work. |
- Cramped Quarters - too small to house properly 650 MPs. It was built for 1,000 people. It needs to house 5,000 comprising MPs, Peers, researchers, civil servants, security, and catering staff.
- Sitting Problem - The House of Commons chamber famously only has enough green leather benches to seat about 427 of the 650 MPs. During major debates, MPs are forced to stand at the bar of the House or sit on the steps
- Office Needs - Victorian gothic architecture doesn't lend itself to open-plan offices, breakout rooms, or high-speed data centres. Many MPs work out of "rabbit warren" offices that are poorly ventilated and lack basic modern amenities.
- Accessibility - The building is a maze of Victorian stairs and narrow corridors. Only 12% of it is accessible to people with disabilities.
Informal Lobbying: A huge amount of parliamentary business happens in the corridors, tea rooms, and "the lobby," where backbenchers can corner Ministers. This, they say, cannot be replicated on a screen.
Voting Procedures: While remote voting was used during the pandemic, it was largely rolled back. The traditional act of physically walking through "Division Lobbies" is seen by many as a vital part of the legislative process.
- Lobbying: Is "corridor whispering" really worth a £24 billion surcharge (the difference between Option 1 and Option 2)?
- Tradition: the Commons Chamber was destroyed in WWII and rebuilt in the 1950s—much of what they call "ancient tradition" is actually younger than some of the MPs sitting in it.
