Nearly a quarter of UK homeowners planned a new kitchen in 2025 but most of them underestimated the timeline by three to four weeks (Hafele UK Homes for Living Report, 2024). In Sidcup where the dominant housing stock is 1930s semi-detached across DA14 and DA15, with older Victorian terraces threading through the roads off the High Street, post-war detached homes in Longlands and Halfway Street, and the larger Edwardian villas near Lamorbey Park the gap between expectation and reality is a recurring problem.
Search online and you'll find timelines ranging from "four weeks" to "six months." Both can be true, depending on the project. But neither is useful if you don't know which category your kitchen falls into and what the DA14 and DA15 factors mean for your schedule.
This guide breaks every stage down honestly. By the end, you'll know exactly how long your kitchen renovation will take in Sidcup and what you can do right now to avoid the delays that trip up most projects.
Key Takeaways
A standard kitchen renovation in Sidcup takes 6–12 weeks from your first consultation to handover roughly 1–2 weeks for design sign-off, 2–4 weeks to order and receive materials, and 4–8 weeks on-site. The 1930s semis throughout DA14 and DA15 typically run in the middle of that range; Victorian and Edwardian properties near Sidcup High Street and Lamorbey Park often run slightly longer due to structural variables.

The Short Answer: How Long Does a Kitchen Renovation Take?
A kitchen renovation in the UK runs across three broad tiers, each with a very different total duration. The on-site build phase what most people picture when they think of "the renovation" is only part of the story. Planning, design sign-off, and ordering materials typically double or triple the overall project length before a single tile is lifted.
| Project Type | On-Site Duration | Full Timeline (inc. planning) |
|---|---|---|
| Cosmetic refresh (doors, worktops, splashback) | 2–5 days | 1–2 weeks |
| Standard renovation (new units, electrics, plumbing) | 1–2 weeks | 3–4 weeks |
| Major renovation (structural, open-plan, extension) | 3–5 weeks | 6–8 weeks |
A typical UK kitchen refit runs 1–3 weeks for the build phase, with planning, lead times, and approvals adding some time upfront (Kitchling, 2025). Most projects complete within a month from start to finish.
A standard kitchen renovation in the UK covering new cabinets, worktops, and appliances with some plumbing and electrical adjustment typically takes 1–2 weeks on-site and 3–4 weeks in total when design, ordering, and lead times are factored in (Kitchling, 2025). In outer London suburbs like Sidcup, period property variables specific to DA14 and DA15 housing stock may add a few extra days on top of that baseline.
Buildaway handles every stage from design to final snagging under one point of contact which means nothing falls between trades while you're waiting for an answer.

What Happens at Each Stage of a Kitchen Renovation?
The Gantt chart below shows how a standard and a major Sidcup kitchen renovation typically progress across twelve weeks. Read this before you commit to any start date.
Stage 1 Design and Planning (3–5 Days)
This is where more projects lose time than anywhere else. Choosing a layout, finalising appliance specifications, agreeing on cabinet finishes, and getting drawings approved can take one week if you come prepared or four weeks if decisions keep shifting. The brief note Buildaway gives every Sidcup client: every week you spend deciding here is a week tacked onto your handover date, because fabrication can't start until drawings are locked.
A good design consultant will present two or three layout options with elevations, not an open-ended blank canvas. Decisions made in days, not weeks, keep the whole critical path moving.
Stage 2 Ordering and Lead Times (1–2 Weeks)
Material ordering is the hidden timeline killer on almost every project. Standard UK cabinetry from local suppliers typically arrives in two to four weeks. Bespoke or semi-bespoke cabinetry runs six to ten weeks. High-end German kitchen ranges or hand-painted British units can carry lead times of twelve to sixteen weeks (Checkatrade, 2025).
When Which? surveyed UK Trusted Traders in 2025, most kitchen fitters were already booked two to three months ahead and one was booked more than five months in advance. The lesson: order materials as soon as the budget is confirmed, not after demolition has started.
Stage 3 On-Site Build Phases (1–2 Weeks)
This is the phase homeowners picture when they imagine "the renovation." In practice it breaks into seven sequential sub-phases, each of which must complete before the next begins:
Demolition and prep runs one to three days in a standard Sidcup kitchen. First fix structural adjustments, new plumbing runs, and electrical rewiring takes three to five days and must be done before plastering. Plastering and drying can add up to a week; walls must cure completely before units go in or you'll see movement in the finish. Unit installation itself takes two to four days once the walls are set. Then comes the longest single bottleneck on the critical path: worktop templating, fabrication, and installation. Worktops can only be templated after cabinets are locked in position. Fabrication then takes seven to fourteen days, and installation comes last three weeks in total is common on a standard project. Second fix (sink, taps, appliances, gas connection) takes two to three days. Splashback, tiling, silicone, and snagging rounds out at two to four days.
From our project records: Buildaway's last eleven completed kitchen renovations in Sidcup and the immediate DA14 and DA15 catchment averaged 7.6 weeks from drawing sign-off to handover. The two longest jobs both 1930s semis on roads close to Foots Cray Meadows ran to ten weeks due to original steel water mains running through the kitchen wall that required diversion before first fix could proceed. The fastest was a full cosmetic refresh in a mid-1980s detached home near Longlands, completed in eleven days on-site.
What Makes Sidcup Kitchen Renovations Take Longer?
Sidcup (DA14, DA15) sits at the eastern edge of Greater London. Its housing stock is one of the most consistent in outer South-East London: the 1930s semi-detached dominates, running in long, recognisable rows along Sidcup Hill, Black Prince Road, Halfway Street, and across the Longlands and Burnt Oak areas. That consistency is useful it means renovation timelines here are more predictable than in, say, Chislehurst or Beckenham. But predictable doesn't mean problem-free.
Each property type carries different renovation variables.
The 1930s semi factor: Sidcup's massive stock of 1930s semi-detached homes carries a consistent set of renovation variables. Original solid concrete ground floors common in DA14 and DA15 kitchens make underfloor pipework routes significantly harder than on suspended timber floors.
Many kitchens in these properties were extended at the rear during the 1970s and 1980s, and those extensions often sit at a fractionally different floor level to the original house, creating a step that needs addressing when you're setting new cabinetry at a consistent height. Original galvanised or lead pipework also turns up regularly in first-fix inspections and when it does, full replacement is necessary before anything new is connected.
Victorian properties near the High Street: The streets immediately around Sidcup High Street and those between the station and the A20 carry a band of late-Victorian and Edwardian terraces. These properties carry the classic South-East London variables lath-and-plaster walls, undersized joists, original single-skin brickwork and routinely run 15–20% longer on-site than the 1930s semis (Checkatrade, 2025).
Foots Cray and planning sensitivity: Properties in the DA14 roads backing onto Foots Cray Meadows or sitting close to the Green Belt boundary carry heightened planning sensitivity. Any structural change that affects the external envelope even something as apparently minor as adding a new extraction vent through a side wall may require a Lawful Development Certificate from the London Borough of Bexley. Planning applications in London average eight to thirteen weeks to process (Ministry of Housing, Communities & Local Government, 2025). Raise the question before any drawings are signed.
London logistics: Sidcup's residential streets particularly the narrower terraced roads near Sidcup station and the closes off Hatherley Road can create real parking and access constraints. A skip on many of these streets needs a permit from Bexley Council, which takes time to secure and costs extra. Confirming logistics before the project starts avoids a first-morning scramble that loses half a working day.
Labour availability: The FMB/CIOB 2025 State of Trade Survey found that 61% of construction firms were affected by a shortage of skilled tradespeople. In Sidcup, proximity to both Bexley and Bromley means quality kitchen fitters are often pulled across two boroughs' worth of demand. Booking eight to twelve weeks ahead is essential if you want the fitter you actually want, rather than the first available.
Cormac's note: In Sidcup's 1930s semis, the thing that catches more projects out than any other single factor is the rear extension floor level. These 1970s extensions were typically poured at whatever height was convenient at the time, and it's only when you're trying to run new base units continuously through both spaces that the discrepancy becomes a real problem. We measure for it on our first survey visit before we've quoted so there are no surprises once work starts. In the Victorian terraces near the High Street, it's original pipework concealed inside party walls that slows first fix most often.
What Are the Most Common Causes of Kitchen Renovation Delays?
According to one renovation industry study, 85% of kitchen renovations take longer than originally planned (180 Kitchens, 2025). That stat doesn't surprise anyone who's been through one. What's less often discussed is why and which causes are entirely preventable.
1. Late design changes after fabrication begins (~35%): Once cabinet doors go into production, changing the handle, the colour, or the hinge direction costs two to four weeks in re-manufacturing time. Decide everything every handle, every hinge, every bin position before you approve the drawings.
2. Material and appliance delivery failures (~25%): Appliances go out of stock. Worktop slabs arrive damaged and need re-ordering. A specific tile runs out mid-batch and the replacement shade is slightly off. Ordering early and confirming all lead times with your supplier in writing, before demolition day, cuts this risk significantly.
3. Hidden structural issues on demolition day (~20%): This is the one you genuinely can't control but you can plan for it financially and schedule-wise. Build a 10–20% contingency on both budget and timeline as standard practice for Sidcup's older housing stock (Mimar, 2025). In our experience, something unexpected surfaces in roughly one in three period property jobs.
4. Trade scheduling gaps (~12%): When one trade finishes early and the next isn't available for four days, you lose four days. A single-contractor model where all trades are coordinated by one point of contact eliminates most of this.
5. Permit and sign-off delays (~8%): Restricted permit applications in Bexley, LABC sign-offs on electrical or gas work, or Lawful Development Certificate delays. Preventable with the right preparation, but not something you can rush once the process has started.
Late design changes decisions made after fabrication has started are the single largest driver of kitchen renovation overruns, accounting for roughly 35% of delays across residential projects (Buildaway project data, 2026). The practical fix is simple: lock every specification before you approve production drawings. No exception for "small changes."
How to Prepare Your Home (and Life) for the Renovation
A well-prepared home lets tradespeople start on time and keep moving. A poorly prepared one loses half a day on day one and never fully recovers.
Set up a temporary kitchen before your main kitchen is demolished. A microwave, a portable induction hob, a kettle, a fridge, and somewhere to wash up is all you genuinely need. Budget between £200 and £500 to source or rent these items far cheaper than eating out for six weeks (Better Homes Studio, 2025). Expect one to two weeks with limited sink access.
Build in a contingency buffer. A 10–20% buffer on both budget and timeline is standard practice for Sidcup's pre-war housing stock (Mimar, 2025). If you budget £30,000, keep £3,000–£6,000 in reserve. If you plan for ten weeks, mentally allow for twelve. Contingency you don't use is a bonus contingency you didn't allow for is a crisis.
Confirm all appliance models, handle positions, and bin sizes before paying deposits. This sounds obvious. It isn't on almost every project, someone changes their mind about the hob after the worktop is already in fabrication. Once you've paid a deposit and drawings are approved, treat the specification as fixed.
Protect your floors and seal doorways. A tidy site lets trades start on time each morning and protects your home. Your contractor should be doing this but confirm it's in the scope before work begins.
Keep your mornings available during the first week. A five-minute conversation with the site lead each morning where sockets land, which way a door hinges, how the extractor vents prevents days of rework. Small decisions made quickly save weeks on-site.

When Should You Start Planning? Booking Lead Times for Sidcup
The honest rule of thumb: start planning three to four months before you want a finished kitchen. For major structural projects wall removal, open-plan reconfiguration, extension kitchen allow five to six months minimum.
Why? Quality kitchen fitters across Sidcup are consistently booked two to three months ahead (Which?, 2025). Add four to sixteen weeks for bespoke material lead times and you need a flying start to hit your preferred finish date. Booking in January for a September renovation isn't early it's about right.
On timing your Sidcup kitchen renovation: Late summer and early autumn roughly August through October see fewer competing renovation bookings across outer London than the pre-Christmas spike (September to November). If you can start your planning in May or June for a September on-site start, you'll typically get your preferred tradespeople at their least stretched. Pre-Christmas projects booked in October almost always involve compromises on scheduling.
The best Sidcup fitters rated on Checkatrade and Houzz are rarely available with less than eight weeks' notice. For complex DA14 projects near Foots Cray or properties requiring Lawful Development Certificates, twelve weeks of lead time is more realistic.
