Planning permission requirements for London kitchen extensions, building regulations for London kitchens (Part G water, Part P electrical, Building Regulations for structural alterations, Party Wall Act), and kitchen costs in London in 2025: PLANNING PERMISSION FOR LONDON KITCHEN EXTENSIONS IN 2025: THE MOST COMMON REASON FOR EXTENDING A LONDON KITCHEN IS TO ADD A SINGLE-STOREY REAR EXTENSION (TYPICALLY 3-6M PROJECTION, FULL WIDTH OF THE HOUSE) TO CREATE AN OPEN-PLAN KITCHEN-DINER-FAMILY ROOM; THE PLANNING RULES FOR LONDON KITCHEN EXTENSIONS ARE COVERED IN DETAIL IN THE EXTENSION PLANNING GUIDE, BUT THE KEY POINTS FOR KITCHEN EXTENSIONS SPECIFICALLY: PERMITTED DEVELOPMENT LIMITS FOR LONDON REAR KITCHEN EXTENSIONS: TERRACE AND SEMI-DETACHED LONDON HOUSES: standard PD limit of 3M PROJECTION from the original rear wall (unless under the Neighbour Consultation Scheme — NCS — where up to 6M IS ALLOWED — SEE EXTENSION PLANNING GUIDE); DETACHED LONDON HOUSES: standard PD limit of 4M (up to 8M under NCS); HEIGHT OF SINGLE-STOREY EXTENSION: maximum 4M at the ridge, 3M at the eaves (maximum 3M within 2M of a boundary); FLAT ROOF EXTENSION: maximum 3M EAVES HEIGHT WHEN WITHIN 2M OF BOUNDARY — MOST LONDON REAR EXTENSIONS ARE FLAT ROOF AND WITHIN 2M OF THE REAR BOUNDARY — SO THE MAXIMUM EAVES HEIGHT IS 3M; ARTICLE 4 DIRECTIONS AND CONSERVATION AREAS: many London conservation areas have Article 4 Directions that remove permitted development rights for rear extensions (even internal works may need planning in some London conservation areas — CHECK WITH YOUR LOCAL PLANNING AUTHORITY); PLANNING APPLICATION FOR LARGER LONDON KITCHEN EXTENSIONS: if the extension exceeds PD limits (e.g., more than 6M depth for a terrace, or any extension in a conservation area), a HOUSEHOLDER APPLICATION is required (£258 fee, 8-12 week determination, see Extension Planning Guide);

KITCHEN SOCKETS: minimum 3 DOUBLES on a ring main for a standard London kitchen (BS 7671 guidance), plus DEDICATED SOCKET OUTLET for dishwasher and fridge; PART G (SANITATION, HOT WATER, AND WATER EFFICIENCY): a new KITCHEN SINK requires a P-TRAP to the waste system (32mm or 40mm waste pipe — 40mm most specified for new London kitchens in 2025); WATER EFFICIENCY: if the kitchen extension is a new dwelling (NOT a renovation of an existing kitchen), Part G water efficiency requirements apply (maximum 125 litres per person per day); KITCHEN WASTE PIPE: horizontal waste pipe run should fall at minimum 1:40 gradient to prevent blockage; INSINKERATOR WASTE DISPOSAL UNIT: requires its own 32mm branch into the waste stack; PART L (ENERGY EFFICIENCY): in a London kitchen extension, the new extension roof must meet PART L new extension U-value target of 0.15 W/m²K (see Flat Roof Guide) and new windows must meet 1.4 W/m²K (see Windows Guide); STRUCTURAL ALTERATIONS FOR LONDON KITCHEN EXTENSIONS: nearly ALL LONDON REAR KITCHEN EXTENSIONS require a STRUCTURAL OPENING in the rear wall to connect the new extension to the existing kitchen — typically a STEEL BEAM (UB SECTION — see Structural Alterations Guide) spanning the full width of the opening; PARTY WALL ACT 1996: if the London extension involves works WITHIN 3M OF OR ADJACENT TO THE BOUNDARY WITH THE NEIGHBOURING PROPERTY (which almost all London rear extensions do), SECTION 6 OF THE PARTY WALL ACT may apply; if the extension is ATTACHED TO THE PARTY WALL (REAR GARDEN WALL OR SIDE WALL SHARED WITH THE NEIGHBOUR), SECTION 2 OF THE PARTY WALL ACT applies (see Party Wall and Structural Guide for details); DRAINAGE AND SEWER BUILD-OVER: if the London kitchen extension is OVER OR WITHIN 3M OF A PUBLIC SEWER, a BUILD-OVER AGREEMENT with Thames Water is required before construction (Thames Water Build-Over Application — online submission at thameswater.co.uk;
