A kitchen renovation is one of the most rewarding home projects you can take on.
But before units start coming out and plumbers appear, it’s worth understanding what a realistic timeline looks like — because most kitchen renovations take longer than homeowners expect, and the ones that go smoothly are the ones that were properly planned.
This guide covers typical timescales, what affects them, and how to prepare so there are no nasty surprises.
Typical Kitchen Renovation Timescales
Here’s a rough guide based on kitchen size and scope. These assume a professional team and all materials are on-site before work begins:
- Small kitchen refresh (new doors, worktop, and sink — keeping the same layout): 2–4 days
- Standard kitchen renovation (new units, worktops, appliances, new sink and tap, minor layout changes): 7–14 days
- Full kitchen refit with layout change (moving sink, gas hob, or oven location — requires pipework and electrical work): 2–4 weeks
- Full kitchen renovation with structural changes (wall removal, utility area or island addition): 4–8 weeks
Sheffield homes vary considerably — from city-centre flats with compact galley kitchens to larger detached properties in the suburbs with open-plan kitchen-dining spaces. The size and condition of what’s already there both affect the timeline significantly.
The most common cause of delays
Waiting for materials. If units are on a 4-week lead time from the supplier and work starts before they arrive, you’ll be without a kitchen twice as long as planned. Always confirm delivery dates before scheduling installation.
What Affects How Long a Kitchen Renovation Takes?
Scope of plumbing changes
Moving the sink to a different wall, adding a dishwasher connection, or relocating a gas hob all require plumbing and potentially gas work. Each of these adds time — not because it’s complicated, but because it needs to be done carefully, and because inspection and sign-off may be required.
If the sink stays in the same position and you’re adding a dishwasher to an existing waste connection, the plumbing element of the job might take half a day. If you’re moving the sink across the kitchen, allow 1–2 days for plumbing alone.
Electrical work required
Modern kitchens have high electrical demand — double oven, hob, dishwasher, fridge-freezer, extractor, sockets, under-cabinet lighting. In older Sheffield homes especially, the existing kitchen circuit may not be adequate for the new layout, and additional circuits may need to be run from the consumer unit.
All notifiable electrical work needs to be certified, which means either using a Part P registered electrician or arranging Building Control notification. Failing to do this can cause problems when you come to sell the property.
Structural changes
If you’re opening up a wall between the kitchen and dining room, or adding a large island, structural changes may be required. This means steel beams, Building Control approval, and a structural engineer. Add 2–4 weeks to the project timeline for this stage alone, plus the Building Control process.
Existing condition of the kitchen
Sometimes old kitchens reveal surprises once units come out — damp walls, outdated pipework, unsafe wiring, or even structural issues. In Sheffield’s older Victorian and Edwardian terraces this is more common than in newer builds. A realistic quote should include a small contingency for unexpected finds.
Material lead times
Bespoke units, stone worktops, and high-end appliances all have longer lead times than standard stock. If your kitchen design relies on materials that take 6–8 weeks to arrive, the project can’t start in earnest until they’re on-site. Factor this into your planning before booking tradespeople.
What Happens Week by Week During a Kitchen Renovation
For a standard kitchen renovation (2–3 weeks, moderate scope) here’s how the timeline typically unfolds:
Week 1: Strip-out and first fix
- Old units, worktops, and appliances removed
- Wall and floor condition assessed — any remedial work carried out
- First-fix plumbing: waste runs, supply pipes, and any relocated connections installed
- First-fix electrical: new circuits, socket positions, and lighting layout roughed in before walls are plastered
- Any plastering or tiling prep work
Week 2: Units and second fix
- Floor coverings installed (if being replaced before units go in)
- Base units fitted and levelled
- Wall units installed
- Worktops measured and templated (stone worktops usually take 5–7 working days to fabricate after templating)
- Second-fix plumbing: sink and tap, dishwasher connections
- Second-fix electrical: sockets, switches, under-cabinet lighting, appliance connections
Week 3: Finishing
- Worktops delivered and fitted
- Splashback tiles or panels installed
- Appliances connected and tested
- Handles, trims, and plinths fitted
- Snag list addressed — any touch-ups, adjustments, or final items
- Clean down and handover
Stone worktops are often the last item to arrive. If you’re having granite or quartz, the worktop fitter will template after units are in, then fabricate off-site. This typically adds 5–10 working days between unit installation and worktop fitting — a gap where you’ll have a functional kitchen but no final surface.
The Plumbing and Electrics Stage: What to Expect
Plumbing and electrical work are where most homeowners have the least visibility into what’s happening — partly because it’s all hidden behind walls and under floors by the time the job is finished.
Kitchen plumbing work
At Heat365, the plumbing element of a kitchen renovation covers the sink and waste connection, dishwasher and washing machine supply and waste, any water softener installation, and gas connection or repositioning for a hob or range cooker.
Gas work is notifiable — it must be carried out by a Gas Safe registered engineer and a certificate issued. If you have a gas hob and you’re moving it or replacing it with a new one, this isn’t a DIY job regardless of how straightforward it looks. Our team is Gas Safe registered and can handle the full gas installation as part of the renovation.
We also deal with any remedial plumbing found during strip-out — old lead pipes, corroded waste connections, or isolation valves that haven’t worked in years. It’s far better to sort these during the renovation than to discover them later through a leak.
Timing within the project
Plumbing happens in two stages: first fix (pipes in walls and floors before they’re sealed up) and second fix (connecting sink, dishwasher, and appliances once units are in). The first-fix stage needs to be right — once walls are plastered and tiled, moving a pipe means undoing a lot of finished work.
How to Prepare Before a Kitchen Renovation Starts
Proper preparation is the difference between a renovation that runs smoothly and one that drags on for twice as long as planned. Here’s what makes the biggest difference:
- Confirm all materials are on-site or have confirmed delivery dates before work starts — units, worktops, appliances, tiles
- Set up a temporary kitchen — a kettle, microwave, and small fridge in another room keeps things manageable
- Clear the kitchen completely before contractors arrive — take everything out of cupboards and clear the area around the kitchen
- Know where your stopcock is — you may need to turn the water off at short notice
- Confirm access arrangements — will someone need to be home, or can keys be left?
- Discuss the snag process — understand what happens if something isn’t right and who to contact
A note on budgeting
Kitchen renovations in Sheffield typically range from £5,000 for a modest refit to £25,000+ for a full bespoke installation. Labour for the plumbing, electrical, and fitting work is usually 30–40% of the total cost. Always get quotes that break down labour and materials separately so you can compare them properly.
Signs It’s Time for a Kitchen Renovation
Beyond the obvious (falling-apart units or a 1980s layout), here are the less visible signs that a renovation is overdue:
- Old or outdated pipework under the sink — plastic push-fit joints from older installations can fail without warning, especially if they’re near hot water pipes
- Insufficient electrical sockets — most older kitchens have far fewer sockets than modern kitchen use requires, leading to extension leads and adapters in a wet environment
- Extractor fan that vents into the ceiling void or recirculates — proper ducted extraction dramatically improves air quality and reduces condensation and mould
- Damp patches on walls behind units — these are often slow leaks from sink waste connections or dishwasher hoses that have been dripping for months
- Units that are structurally sound but don’t reflect how you use the kitchen — sometimes a layout change is the only real solution to a kitchen that doesn’t work
Frequently Asked Questions
Do I need planning permission for a kitchen renovation?
In most cases, no — internal kitchen renovations don’t require planning permission. However, if you’re removing a structural wall, extending the property, or your home is listed, you’ll need to check with Sheffield City Council. Building Regulations approval (separate from planning permission) may be required for gas work, electrical circuits, and structural changes.
Can I live in the house during a kitchen renovation?
Yes, most people do — but it’s worth planning for reduced access to the kitchen for 1–3 weeks. A temporary setup (microwave, kettle, mini fridge) in another room makes it much more manageable. The messiest and noisiest stages are usually strip-out and any plastering or floor work.
Do I need to hire separate tradespeople, or can one company handle everything?
Heat365 handles the plumbing and gas work as part of a kitchen renovation project and works alongside kitchen fitters, electricians, and builders. We can also recommend trusted tradespeople for the other elements if you need them — we’ve worked on many Sheffield kitchen projects and have established working relationships with quality local contractors.
How far in advance should I book?
For a renovation starting in the next 4–6 weeks, book as soon as you have your units and materials confirmed. Good tradespeople in Sheffield are often booked 3–6 weeks out. Getting the plumbing and gas booked first is wise, as these stages need to fit around the rest of the project timeline.
What warranty should I expect on the work?
At Heat365, our plumbing and gas work carries a 12-month workmanship warranty. Manufacturers’ warranties on appliances and taps are separate and typically 1–5 years depending on the product. We always provide a Gas Safe certificate for any gas work carried out.
