A London kitchen renovation sits at the intersection of three notifiable regimes. Any gas appliance or hob installation needs a Gas Safe registered engineer — unregistered gas work is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Any new circuit, consumer-unit change, or special-location work triggers Part P and needs certification by a competent-person scheme (NICEIC, NAPIT, Stroma, or ELECSA) or a Building Control Notice. Any structural opening to knock through to a dining room triggers a Building Notice or Full Plans application and almost always a steel RSJ with engineer's calculations.

Add the leasehold reality — roughly 70% of London flats are held on long leasehold, and a significant kitchen reconfiguration usually needs a written Licence to Alter from the freeholder — and the paperwork is often longer than the build.

AskBaily routes your London kitchen renovation to one vetted London builder who knows Gas Safe, Part P, Building Control, and leasehold consent inside-out.

What a London kitchen renovation involves

  • Structural. Steel RSJ + Building Notice or Full Plans for any load-bearing wall removal. Structural engineer's calculations are mandatory.
  • Gas. Gas Safe registered engineer for hob, oven, or boiler relocation. Certificate filed on completion.
  • Electrics. Part P competent-person certification for new circuits, consumer-unit upgrades, and special-location work (within 600 mm of a sink).
  • Leasehold. Licence to Alter + freeholder consent. Deed of variation if the lease restricts structural alterations.
  • VAT. 20% standard rate. 5% reduced rate applies to certain energy-saving kitchen installations and properties empty for 2+ years.

Frequently asked questions

Do I need Building Regulations approval for a London kitchen renovation? Not for a like-for-like refit. As soon as you remove a load-bearing wall, add a new circuit, move gas, or change the ventilation strategy, you need either a Building Notice or Full Plans submission. Specialist certificates (Gas Safe, Part P) cover the notifiable sub-trades.

What is a Licence to Alter and why does my freeholder want one? If you own a leasehold flat, your lease almost certainly requires the freeholder's written consent before structural or significant alterations. The Licence to Alter documents the consent, conditions, and any surveyor costs. Expect £750-£3,000 in freeholder fees for a typical flat kitchen renovation.

How much does a London kitchen renovation cost? £35,000-£85,000 for a mid-spec Inner London flat kitchen (full fit, mid-range appliances, structural opening). £100,000-£250,000 for a prime-central kitchen with bespoke cabinetry. Budget 10-14 weeks from strip-out to handover.

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
