Types of House Renovation in London

Full house renovation: Complete gut and refurbishment of the entire property. New consumer unit, complete rewire, new central heating, new plumbing, internal reconfiguration if required, full plastering, new flooring, new kitchen, new bathrooms and full redecoration. The most comprehensive option — typically required for properties that have not been updated for 20+ years or newly purchased properties requiring full upgrade.

Renovation with extension: The most popular combination in London — combining a house extension with a full or partial internal renovation to completely transform the property. Adding a wraparound extension while renovating the entire interior creates a new home from an existing property.

Partial renovation: Targeted upgrade of specific rooms or areas. Kitchen and bathroom renovations are the most common, generating strong returns on investment and transforming the most-used spaces.

Period property renovation: Specialist renovation of Victorian, Edwardian and Georgian properties requiring careful restoration of period features alongside modern upgrades. LCCL Construction has extensive experience with period property renovation across London.

How Long Does a House Renovation Take in London?

A full house renovation takes 12 to 20 weeks on site depending on scope. A partial kitchen and bathroom renovation takes 6 to 10 weeks. A single kitchen renovation takes 3 to 5 weeks. A single bathroom renovation takes 2 to 3 weeks. Projects combining renovation with extension take longer due to the construction phase.

House Renovation or Moving? Why Renovating Makes More Financial Sense in London

For most London homeowners renovating — and potentially extending — makes better financial sense than moving. The costs of buying and selling in London include stamp duty, estate agent fees, legal fees and moving costs — typically £50,000 to £150,000 for a family house. A full renovation and extension costing £180,000 – £300,000 inc. VAT (£150,000 – £250,000 + VAT) transforms your existing property into what you need without these costs, adds significant value and avoids the upheaval of moving.
