Kitchen and Bathroom Procurement for London Renovations 2025: What to Buy, When to Buy It, and What to Watch Out For

The procurement timeline for a kitchen or bathroom in a London building project works backwards from the installation date. Starting with installation and working back: Kitchen installation date: typically 2-3 weeks before practical completion (second-fix joinery and kitchen fitting is towards the end of the programme). Second-fix plumbing (sink, dishwasher) and second-fix electrics (socket outlets, appliances, extractor fan connection) must follow kitchen installation — allow 1-2 days for plumbing and 1-2 days for electrics after the kitchen is installed. Kitchen must be on site before installation: the kitchen must be delivered to the site and stored (or delivered directly for fitting) at least 1-2 days before the installation team arrives. Lead time from order to delivery: a standard range kitchen (e.g., Magnet, Howdens, Wren) has a lead time of 3-6 weeks. A bespoke kitchen (e.g., a designer kitchen from a London kitchen studio — Roundhouse, Plain English, deVOL, Tom Howley, John Lewis of Hungerford) has a lead time of 12-20 weeks. A fully bespoke hand-painted, hand-built kitchen from a specialist maker: 20-26 weeks. Working backwards: if the kitchen installation is week 20 of a 22-week programme: standard range kitchen must be ordered by week 14-17. Bespoke kitchen must be ordered by week 0 (or even before the programme starts — before the building contract is signed). For a London renovation where a bespoke kitchen is planned, the kitchen designer must be engaged at the beginning of the project — during the design stage — not at the halfway point of the build. Bathroom procurement timeline: bathroom installation (tiling, fitting sanitaryware, shower tray, bath, WC, basin) is typically in the second half of the programme — weeks 14-18 in a 20-week full refurbishment programme. The bathroom goods (bath, WC suite, basin and pedestal or vanity unit, shower tray, shower enclosure or frameless glass, heated towel rail, taps and mixers) must be on site before the tiler finishes. Lead times: standard range (e.g., Bathstore, Bathrooms to Love, B&Q, Screwfix, Wickes): 1-4 weeks for standard stocked items. Mid-range (e.g., Burlington, Heritage, Duravit, Hansgrohe, Vado, Crosswater): 2-6 weeks for most items, longer for bespoke or made-to-order. Premium (e.g., Villeroy & Boch, AXOR, Antonio Lupi, Agape): 4-12 weeks for made-to-order items. Bespoke or handmade: 12-20 weeks. Stone and large-format tiles: 2-8 weeks for standard stock; 8-16 weeks for special order or imported stone. Order tiles before tilers start — a tiler cannot work if the tiles have not arrived. RCB standard condition: all second-fix materials (including kitchen goods and bathroom goods — sanitaryware, tiles, taps, bathroom accessories) are client-supplied to site. This means the client is responsible for ordering, receiving, and having all materials on site when the relevant trade is ready to fit them. A builder who turns up to tile or fit the kitchen and finds the tiles or kitchen units have not arrived will charge waiting time or move on to another job — adding cost and delay to the programme.

The most common kitchen and bathroom procurement mistakes on London building projects: Ordering to a room measurement taken before the first-fix work is complete: the room size and configuration changes during the first-fix stage (new drainage, new stud walls, new electrics, new plumbing positions). A kitchen ordered before the first-fix work is confirmed and the walls are at first-fix stage may not fit correctly. Best practice: take final measurements for kitchen units after first-fix electrics and plumbing are complete and the stud walls are in their final positions. For standard range kitchens (3-6 week lead time) this is easily achievable. For bespoke kitchens (12-20 week lead time), the design must be finalised to drawing level during the design stage (pre-construction) and any first-fix changes communicated to the kitchen designer immediately. Ordering tiles before the room is tiled (wall tiles before the first-fix plumbing and electrics in the bathroom are confirmed): floor and wall tile quantities are calculated from the confirmed room dimensions, allowing for cuts (typically 10-15% wastage). Tile quantities ordered from early sketch dimensions and not updated after first-fix often result in incorrect quantities — either too few tiles (causing a delay while new tiles are ordered, often from a batch that does not match exactly) or excess tiles with no return policy. Best practice: calculate tile quantities from the confirmed room dimensions after first-fix. Order from the same batch — check the batch number (the batch or shade lot number, typically printed on the box) of all tile boxes before delivery is accepted. Tile batches change colour between production runs — a tile from batch 001 and a tile from batch 002 can look visibly different. Misunderstanding the scope of 'client-supplied': in a building contract where second-fix materials are client-supplied, the client is responsible for all items that will be installed in the second-fix stage — not just the kitchen and bathroom. This typically includes: door hardware (handles, hinges, locks, letter boxes, door numbers); floor finishes (if client-supplied — engineered oak boards, LVT, or tile for floors); light fittings (ceiling roses, pendant lights, downlights, bathroom fittings — often a significant oversight: the builder orders standard recessed downlights if the client hasn't specified, or leaves fitting incomplete if the client hasn't provided items); window cills and window boards (where windows have been replaced and new cill boards are needed); stair finishes (stair nosings, balustrade components where the client has chosen specific materials). Best practice: produce a complete schedule of client-supplied items at the start of the project — covering every item that will be fitted in the second-fix stage by the contractor, with the specification, the source (supplier), the estimated lead time, and the responsible person (client or building manager). Choosing a kitchen or bathroom specification that the selected contractor cannot install: a high-end London kitchen with integrated Gaggenau appliances, a Bulthaup handleless system with a specific installation sequence, or a bathroom with an Italian freestanding bath requiring specific floor connection details needs an installer with experience of that specification. Not all kitchen and bathroom fitters are experienced with premium specification products. Best practice: confirm with the Principal Contractor that they have experience of the specific kitchen or bathroom specification you are proposing before committing to the design.
