Pricing & Service Charges
— Pricing · South London
Honest pricing for South London renovations.
Realistic budget ranges from two decades of South London projects — kitchens, bathrooms, extensions, full-house refurbishments, and everything in between.
Every range below is based on actual projects we’ve delivered across Wandsworth, Wimbledon, Dulwich, Chelsea, Kensington, Richmond, Beckenham, Bromley, Banstead, Croydon and surrounding South London boroughs. Final prices depend on size, finishes, structural work and the condition of the existing property. Site visit and detailed fixed-price quote within 48 hours, free of charge.
— Key factors
What affects your final price.
Four factors drive the range you’ll see in any honest quote. We’re transparent about each one before work starts.
Location
Inner London postcodes (Chelsea, Kensington) typically run 10-20% above outer boroughs (Banstead, Bromley) due to access, parking and waste removal.
Material specification
Mid-range vs premium can double the budget of a single room. We price the same room three ways so you see exactly what each level buys you.
Hidden conditions
Period properties often hide damp, lead pipes, lath-and-plaster, old wiring or rotten joists. We build a sensible contingency into every quote and flag findings before proceeding.
Regulations & approvals
Planning, Building Regs, Party Wall, conservation area consent, Article 4 directions — all checked early. We work with trusted architects or alongside yours.
— Three tiers
How we tier every project.
Most categories below are priced in three tiers. Same scope of work, different specification levels. We’ll quote the same room across all three so you can see exactly what each tier delivers.

Standard
Family home upgrade
Bespoke joinery, premium materials, structural alterations possible, integrated lighting and finishes throughout. The most common South London family specification.

How quickly does LMDEC provide a quote?
LMDEC carries out a free site visit with no obligation and returns a written, itemised fixed-price quote within 48 hours. The quote breaks down labour, materials, finishes and contingency.
Are LMDEC’s prices fixed?
Yes. Every LMDEC quote is fixed-price and fully itemised before work starts. If hidden conditions are uncovered during the build, such as asbestos, rotten timbers, lead pipes or failed wiring, LMDEC informs the client immediately with the costs and the options, and the client decides before any further work is carried out.
Does LMDEC offer a warranty?
Yes. Every project carries a two-year workmanship warranty, and LMDEC includes a return visit six months after completion to inspect the build. LMDEC also does not leave site until snagging is complete.
Is LMDEC insured?
Yes. LMDEC LTD carries £2,000,000 of public liability insurance.
Who carries out the gas and electrical work on an LMDEC project?
Gas work is carried out by individually qualified Gas Safe registered engineers and electrical work by individually qualified NICEIC certified electricians, all working as subcontractors under LMDEC’s project management. Certification is issued on completion where required, and registration numbers are available on request before work starts. LMDEC LTD does not hold Gas Safe or NICEIC registration itself.
How many projects does LMDEC run at the same time?
A maximum of three at any one time. This is a deliberate limit so that every client has the full attention of their project manager from quote through to handover.
Does LMDEC provide architectural design?
No. LMDEC is a building contractor, not an architecture practice. It works alongside the client’s own architect or recommends trusted architects and structural engineers. Architect, structural engineer, party wall surveyor and local authority fees are charged separately from the build cost.
Does LMDEC handle planning permission and Building Regulations?
LMDEC checks planning permission, Building Regulations, Party Wall Act requirements, conservation area consent and Article 4 directions before work starts, and manages Building Regulations compliance and sign-off during the build.
How long has LMDEC been operating?
Since 2014. The founder, Lukasz, began trading as a self-employed sole trader renovating South London homes in 2014, and incorporated the business as the limited company LMDEC LTD in 2018, company number 11635394. It has been operating continuously in South London throughout.
Do LMDEC’s prices include VAT?
No. All prices published by LMDEC exclude VAT unless a page states otherwise. Architect, structural engineer, party wall surveyor and local authority fees are also separate. The final price is always confirmed in writing before work starts.
