Decision framework
Refurbish or Rebuild: Choosing the Right Approach in Belsize Lane
The biggest single decision on a electrical rewire project is whether to refurbish the existing property or demolish and rebuild. Here's how we frame the trade-offs for Belsize Lane owners.
1How much of the existing structure is sound?
Refurbish
Most Belsize Lane period homes have sound brick, timber, and roof structures that are worth retaining. Refurbishment preserves character and avoids planning risk.
Rebuild
If the existing structure has serious subsidence, fire damage, or non-compliant additions, demolition and rebuild may be the cleaner route.
Our recommendation
Refurbish unless a structural engineer flags major issues at survey.
2What does the planning landscape allow?
Refurbish
Conservation areas in Belsize Lane typically restrict demolition. Refurbishment, with permitted-development additions, is usually faster to consent.
Rebuild
New-build replacement requires full planning consent and often an environmental impact assessment. Listed buildings rule out rebuild entirely.
Our recommendation
Refurbish for almost all conservation-area and listed properties.
3How does the budget compare?
Refurbish
Refurbishment costs typically £1,200 – £2,500 per sqm for premium spec, with shorter programmes and lower professional fees.
Rebuild
New-build costs £3,000 – £5,000+ per sqm in prime London, plus 18-30 months of design, planning, and demolition costs.
Our recommendation
Refurbish for £1m – £3m budgets; rebuild only justified above £3m on the right plot.
4What is the energy and comfort upgrade gap?
Refurbish
Internal wall insulation, MVHR, and slim-double-glazed sashes can lift period homes to EPC C/B without altering external appearance.
Rebuild
New-build can hit EPC A and Passivhaus standards with mechanical ventilation, triple glazing, and air-tight detailing.
Our recommendation
Refurbishment usually closes the comfort gap at lower cost in period properties.
5What about resale value and marketability?
Refurbish
Refurbished Belsize Lane period homes command a premium for character. Buyers in this market value original features.
Rebuild
New-build replacements in period streets can struggle to match comparable refurbished sale values.
Our recommendation
Refurbish if your property has period character. Rebuild only on plots without heritage value.
How we sequence the build
Sequencing Your Electrical Rewire Project
An 18-week electrical rewire project breaks into 8 phases, each with specific trades, deliverables, and risks. Understanding the sequence helps you anticipate questions, decisions, and on-site moments.
Phase 1: Pre-construction
Trades on site
Architect Structural engineer Surveyor Project manager
Deliverables
- Full survey including drains, services, and structural integrity
- Detailed design package with specifications and material schedule
- Planning permission and Building Control submissions where required
- Party Wall agreements coordinated with neighbours
- Fixed-price contract with itemised quote
Risk note
Hidden defects (damp, asbestos, non-compliant additions) are usually discovered here — budget a 10% contingency.
Phase 2: Site setup & strip-out
Trades on site
Site manager Strip-out crew Skip and waste contractors
Deliverables
- Site protection: dust screens, floor coverings, scaffold
- Strip-out of all existing finishes, fittings, and services
- Confirmation of structural condition once exposed
- Asbestos survey and remediation if pre-1999 property
- Final scope confirmation with client
Risk note
Strip-out always reveals more than the survey predicted. Quick decision-making protects programme.
Phase 3: Structural works
Trades on site
Structural engineer Steel fixers Bricklayers Carpenters
Deliverables
- Steel beams, posts, and lintels installed per engineer's design
- Wall removals, openings, and structural alterations
- Foundation works for new walls or extensions
- New floor structures and joist work where required
- Building Control structural inspection and sign-off
Risk note
Steel fabrication lead times can run 4-6 weeks — order early to avoid programme delay.
Phase 4: First-fix services
Trades on site
Electricians Plumbers Heating engineers Insulation contractors
Deliverables
- Full rewire to 18th edition standards with NICEIC certification
- New plumbing in PEX or copper with manifolds
- Heating system installation: boiler, cylinder, MVHR if specified
- Insulation to walls, floors, and roof
- First-fix for AV, smart home, security, and data
Risk note
First-fix sequencing matters: services must be coordinated to avoid clashes before plastering.
Phase 5: Plastering & flooring substrate
Trades on site
Plasterers Floor screeders Carpenters Tilers (substrate)
Deliverables
- Full skim plastering throughout
- Floor screeding with underfloor heating where specified
- Internal stud walls, ceilings, and architectural detailing
- Window and door reveals finished
- Subfloor preparation for finished flooring
Risk note
Plaster needs proper drying time (1 week per coat) — rushing this stage risks cracking and finish defects.
Phase 6: Second-fix services
Trades on site
Electricians Plumbers Heating engineers AV installers
Deliverables
- All sockets, switches, and lighting fittings installed
- Sanitaryware, taps, showers, and radiators connected
- Boiler commissioning and heating zoning configured
- Smart home, AV, and security systems commissioned
- Building Control electrical inspection
Risk note
Specification of fittings should be locked before week 8 to avoid lead-time delays.
Phase 7: Joinery, kitchens & bathrooms
Trades on site
Bespoke joiners Kitchen fitters Stone fitters Tilers
Deliverables
- Bespoke joinery installation: wardrobes, media walls, pantries
- Kitchen units, worktops, splashbacks, and appliances fitted
- Bathroom tiling, sanitaryware, and shower screens
- Internal doors, architraves, and skirting installed
- Stair restoration or replacement completed
Risk note
Stone worktops require templating after units are installed — adds 2 weeks lead time.
Phase 8: Finishing & handover
Trades on site
Decorators Floor finishers Cleaners Snagging team
Deliverables
- Decoration: full mist coat, undercoat, two top coats
- Floor finishes laid: engineered timber, stone, or carpet
- Final clean and snagging walkthrough
- Building Control sign-off and warranty paperwork
- Handover pack with manuals, certificates, and aftercare schedule
Risk note
Final 5% of works always takes 20% of effort. Defect-free handover requires methodical snagging.
