What Should I Know Before Starting a Home Renovation Tips in London?

Planning Permission and Permitted Development


Not all renovations need planning permission. Many house extensions and loft conversions fall under permitted development rights, which means you can proceed without a formal planning application. However, properties in conservation areas, listed buildings and flats usually require planning permission. Always check before starting work. A good design and build company will advise you on this during the initial consultation.


Building Regulations


Building regulations approval is required for almost all structural work, including extensions, loft conversions, internal structural alterations and new bathrooms. Building regulations cover structural integrity, fire safety, insulation, ventilation, drainage and electrical safety. Your chosen company should handle building regulations applications and inspections as part of their service.


Party Wall Agreements


If your renovation involves work within 3 metres of a shared wall with a neighbour, you may need a party wall agreement under the Party Wall Act 1996. This is common with rear extensions and loft conversions on terraced and semi-detached houses in London. The process typically takes 4 to 8 weeks and should be started early.


Realistic Timelines


Home renovations take longer than most people expect. A rear extension takes 10 to 16 weeks to build. A loft conversion takes 8 to 14 weeks. A full house renovation can take 4 to 8 months. The design and planning phase adds another 6 to 12 weeks before construction starts. Build these timelines into your plans.


Budget and Contingency


Always include a contingency of 10% to 15% of your total budget. Unexpected issues like hidden structural problems, asbestos, drainage complications or material price changes can add costs. A transparent company will provide a detailed written quote before work begins.


Choosing the Right Company


Check experience, reviews across multiple platforms, accreditations such as LABC and NFB membership, whether they offer a complete design and build service, warranty options and their portfolio of completed work. LCCL Construction meets all of these criteria with over 20 years of experience, 200+ reviews rated 4.7/5, LABC Award Winners 2024 and NFB membership.


Living in Your Home During Renovation Home Renvation Tips London


For most extensions and loft conversions, you can stay in your home during the build. Full house renovations may require you to move out temporarily depending on the scope of work. Discuss this with your company during the planning stage.
