What affects the cost?

• Whether the wall is load-bearing (RSJ needed) or partition (much cheaper)
• Length of opening — wider openings need bigger steels
• Number of storeys above — first-floor opening is cheaper than ground-floor under two storeys
• Structural engineer fee — typically £350–£800
• Building control fee — £250–£600
• Making good (plastering, flooring, electrics) — often half the total cost
• Whether services (radiators, sockets, pipework) need rerouting

Cost breakdown

Cost by UK region

Regional pricing varies by up to 50 %, mostly driven by labour rates. These multipliers apply to the base UK cost:

Planning permission?

Not required for internal walls; building regulations sign-off needed for structural changes

How long does it take?

3–10 days typical, plus design and approvals time beforehand.

DIY vs Professional

Difficulty: Pro required. UK building regulations and Part P/Gas Safe rules mean most of this work must be done by registered professionals. Even where DIY is permitted, paying a pro is usually faster and more reliable.

How to save money

• Always commission a structural engineer — never rely on the builder's "it'll be fine"
• Tell building control before work starts — retrospective applications cost double
• Choose a steel size with 25 % spare capacity for future loads (loft conversions, solar)
• Box the steel in flush rather than leaving an "Edwardian" lintel — looks cleaner and adds value
• Get a single contractor responsible for the steel + make-good — fewer finger-pointing problems

Frequently asked questions

How do I know if a wall is load-bearing?

Typical signs: it runs perpendicular to the joists above, it’s thicker than 100 mm, it sits directly above a wall on the floor below, or it’s a party/external wall. Always confirm with a structural engineer before any work — a £350 site visit is far cheaper than a collapse.

Do I need building regulations to remove a wall?

Yes — any structural change needs building regulations approval. Submit a building notice (cheap, fast) or a full plans application. Inspections happen at steel installation and on completion.

How long does it take to remove a wall?

Partition wall: 1–2 days. Load-bearing wall with RSJ: 3–5 days for the structural work, plus 2–3 days for making good. Add 4–8 weeks for engineer + building control beforehand.
