1. The Reality: Kitchen Renovations Don't Fail by Accident
Kitchen renovations rarely go wrong because of bad luck. They fail because of planning gaps.
In Greenwich postcode SE10 — covering Greenwich town centre, Maze Hill, East Greenwich, Vanbrugh Park, Park Vista and the streets around Greenwich Park and the Royal Observatory — many homes have:
- Listed and conservation area properties where structural and external alterations carry additional consent requirements
- Tall Georgian terraces on Crooms Hill and Maze Hill with original services running through multiple floors
- Victorian and Edwardian semis in Vanbrugh Park and East Greenwich with electrical systems never comprehensively updated
- Basement and lower ground floor kitchens where moisture management and ventilation require specific attention
When those conditions are not identified early, problems surface mid-project. This guide explains exactly what can go wrong during a kitchen renovation and how to prevent it.
2. Why Kitchen Renovations Go Wrong in Greenwich Homes
Greenwich housing stock brings specific challenges:
- Georgian terraces around Crooms Hill and Greenwich Market with lead pipework and original stone drainage channels still in active use
- Victorian properties along Maze Hill and Straightsmouth with fuse boards installed at original construction and never replaced
- Edwardian semis in Vanbrugh Park and East Greenwich with undersized consumer units and no RCD protection
- Listed and conservation area buildings throughout SE10 where extraction routes, structural works and even surface finishes may require consent before work begins
These are not rare cases. They are typical scenarios local contractors encounter in SE10 week in, week out.
The 10 Things That Go Wrong
Each issue below follows the same pattern: what fails, why it happens, why it is common locally, and how to avoid it.
1. Poor Layout Planning
What goes wrong
The kitchen looks good but doesn't function properly. The working triangle between hob, sink and fridge is broken. Worktop space runs out where it is needed most during meal preparation.
Why it happens
Design decisions are rushed. Workflow is not tested against how the household actually cooks before installation begins.
Why common in Greenwich
Period kitchens across SE10 — basement rooms in Georgian terraces near Eliot Place, narrow rear rooms in Victorian terraces along Burney Street, galley kitchens in Edwardian semis in Vanbrugh Park — were designed for a domestic life that bears no resemblance to today. Adapting these spaces for contemporary use without deliberate planning produces a kitchen that looks updated but works no better than what it replaced.
How to avoid it
Plan zones carefully. Mock up walking routes. Avoid changing layout mid-project. Changes during installation can add £500 to £2,000 per adjustment.
2. Underestimating Structural Work
What goes wrong
A wall is removed and later confirmed as load-bearing.
Why it happens
Assumptions are made without a prior structural assessment.
Why common in Greenwich
Georgian and Victorian properties along Maze Hill, Park Vista and the roads below Greenwich Park carry floor and roof loads through internal walls in ways that are not visible from inspection alone. These buildings were not designed with open-plan living in mind, and the structural cost of creating it can be significant.
How to avoid it
Have structural checks done before quoting. Removing a load-bearing wall can cost £3,000 to £10,000 including engineer fees and Building Control.
3. Ignoring Plumbing Upgrades
What goes wrong
Low water pressure, leaks, or waste pipe blockages appear months later.
Why it happens
Old pipework is left in place to save cost and time.
Why common in Greenwich
Georgian properties near Greenwich Market and Victorian terraces along Straightsmouth and Burney Street retain original lead supply lines and clay drainage channels in many cases. Neither is adequate for a repositioned sink, an added appliance connection or a modified kitchen layout.
How to avoid it
Inspect and upgrade plumbing during first fix stage. Budget for £400 to £1,500 if relocating sinks or appliances.
4. Electrical Overload or Poor Socket Planning
What goes wrong
Insufficient sockets. Circuits trip under load.
Why it happens
Old wiring cannot support induction hobs, ovens and integrated appliances running together.
Why common in Greenwich
Victorian semis along Maze Hill and Edwardian properties in Vanbrugh Park and East Greenwich retain electrical installations calibrated for a fraction of what a modern kitchen demands. Consumer units in these homes typically lack available capacity and RCD protection required under current Building Regulations.
How to avoid it
Upgrade circuits and plan socket locations early. Kitchen electrical upgrades can range £400 to £1,200.
5. Inadequate Ventilation
What goes wrong
Condensation and mould appear within months of the kitchen being in use.
Why it happens
Extractor fans are undersized or poorly positioned relative to the room's ventilation requirements.
Why common in Greenwich
Solid masonry walls throughout SE10's period stock create cold surfaces where condensation forms readily. Basement kitchens in Georgian terraces near the waterfront and rear north-facing kitchen extensions in Victorian properties throughout East Greenwich are particularly vulnerable. In listed buildings, extraction duct routes through original walls may require consent — making early planning essential.
How to avoid it
Install compliant extraction systems meeting Part F requirements. Confirm duct routes in listed properties before any cabinetry positions are fixed.
6. Poor Quality Installation
What goes wrong
Crooked cabinets. Uneven tiling. Misaligned worktops.
Why it happens
Choosing the cheapest quote. Poor supervision throughout the project.
Why common in Greenwich
Greenwich attracts high-specification kitchen projects. Labour rates in SE10 are 15–25 percent above the national average. A poor installation in a period property where surrounding finishes are already of a high standard is immediately and permanently apparent.
How to avoid it
Vet contractors thoroughly. Request references from SE10 or adjacent SE postcodes. 50 percent of renovation regrets in 2025 were linked to poor workmanship.
7. Appliance Delivery Delays
What goes wrong
Kitchen sits incomplete waiting for appliances.
Why it happens
Appliances not ordered early enough in the project timeline.
Why common in 2026
Premium and integrated appliances regularly specified in SE10 — range cookers, integrated refrigeration, wine coolers — carry lead times at the longer end of the range. Delivery waits of 4–12 weeks remain common across South East London.
How to avoid it
Order appliances 8–12 weeks before installation. Confirm stock availability in writing at the point of purchase.
8. Budget Underestimation
What goes wrong
Final cost exceeds quote by 20–50 percent.
Why it happens
No contingency for hidden structural, plumbing or moisture issues.
Why common in Greenwich
Period properties throughout SE10 regularly reveal concealed defects once original finishes are removed. Properties near the Thames and in low-lying parts of East Greenwich carry additional moisture risk at ground and basement level. Unforeseen costs of £2,000–£5,000 are a common outcome in this housing stock.
How to avoid it
Include 10–20 percent contingency in your budget.
9. Poor Trade Coordination
What goes wrong
Electrician arrives before plumbing is complete. Worktops templated too early.
Why it happens
Lack of project management across multiple independent trades.
Why common in Greenwich
Trades serving SE10 and adjacent areas including Lewisham, Deptford and Woolwich manage several concurrent projects. In a listed or period property where each stage is interdependent, poor sequencing amplifies delay and cost in ways it would not in a simpler build.
How to avoid it
Ensure one contractor manages sequencing and scheduling throughout.
10. Skipping Proper Finishes and Detailing
What goes wrong
Gaps, poor sealing, unfinished edges.
Why it happens
Rushed completion to move onto the next project.
Why common in Greenwich
In SE10, where properties and specifications are of a premium standard, the gap between a well-finished kitchen and a rushed one is more visible than almost anywhere else in South East London.
How to avoid it
Include a snagging inspection before final payment. Retain 5–10 percent of the final amount until all items are resolved.
4. The Cost of Getting It Wrong
Mistakes are expensive.
- Rework costs £3,000–£8,000 on average
- Delays extend projects from 2 weeks to 4–6 weeks
- Non-compliant work in listed buildings can result in enforcement action requiring reversal at the owner's expense
- Surveyors flag structural or electrical issues during resale — particularly consequential in SE10's premium property market
The median UK kitchen cost is now £17,500, up 34 percent since 2024. In Greenwich, where specification levels sit significantly above the national average, a failed renovation represents a considerably greater financial loss.
