Planning a home renovation in London can feel overwhelming. Whether you want to extend your kitchen, convert your loft, renovate your entire house or simply modernise your living space, knowing where to start makes the process far less stressful. This step-by-step guide explains exactly how to get started with a home renovation project in London, from initial ideas through to finding the right company and beginning work.

How to Get Started with a Home Renovation Project in London

Step 1: Define What You Want to Achieve Home Renovation London


Before contacting any builders or architects, spend time thinking about what you actually want from the renovation. Are you looking for more space? A modern kitchen? An extra bedroom? A complete transformation? Write down your priorities and think about how you use your home now and how you want to use it in the future. Walk through your house room by room and note what works and what does not.


Step 2: Set a Realistic Budget


Home renovation costs in London vary significantly depending on the scope of work. A kitchen extension typically costs £42,000 – £153,600 inc. VAT (£35,000 – £128,000 + VAT). A loft conversion costs £32,400 – £148,800 inc. VAT (£27,000 – £124,000 + VAT). A full house renovation can cost £120,000 – £360,000 inc. VAT (£100,000 – £300,000 + VAT) or more depending on the size and specification. Set a budget range rather than a fixed number, and include a contingency of 10% to 15% for unexpected costs.


Step 3: Research and Choose the Right Company


Look for a design and build company that handles everything under one roof — architecture, planning, building regulations, structural engineering, construction and finishing. This eliminates the need to hire and coordinate separate professionals. Check their experience, reviews, accreditations and completed projects. LCCL Construction offers a full design and build service across London and Hertfordshire with over 20 years of experience, 200+ reviews rated 4.7/5, and LABC Award Winners 2024.


Step 4: Book a Consultation


A good construction company will offer a free initial consultation. During this meeting, you discuss your project, your priorities, your budget and your timeline. The company assesses your property and advises on what is possible — including planning permission requirements, structural considerations and design options.


Step 5: The Design Phase


Once you have chosen your company, the design phase begins. This includes a measured building survey of your property, architectural drawings showing the proposed layout, and applications for planning permission and building regulations. A design and build company handles all of this for you.


Step 6: Pre-Construction


Before construction starts, structural engineer calculations are completed, party wall agreements are arranged with neighbours where required, and materials are procured. Your project manager will agree a construction programme with clear milestones and timelines.


Step 7: Construction and Completion


Construction begins with your dedicated project manager overseeing every stage. Regular updates keep you informed of progress. The project finishes with building control sign-off, snagging and handover of your transformed home.
