Most renovation problems trace back to decisions made, or not made, before work ever started. A bit of upfront planning around budget, permissions, access and living arrangements saves a lot of stress once the builders arrive. Here are the five things worth sorting out first.
1. Set a realistic budget with contingency
Every renovation budget should include a contingency of at least ten to fifteen percent for unforeseen issues, which is particularly important in older North London properties where problems such as damp, outdated wiring or structural movement are often only discovered once walls are opened up. Get a clear, itemised fixed-price quote rather than a rough estimate, so you know exactly what is and is not included before work begins.
2. Establish what permissions you need
Not all renovation work needs planning permission, but structural changes, extensions, loft conversions and anything affecting a property in a conservation area usually do need either planning consent, a Lawful Development Certificate, or at minimum building regulations approval. If your property shares a wall or boundary with a neighbour, a party wall notice may also be required before certain works can begin. Establishing this early avoids delays once your builder is booked in.
3. Think about access and disruption
Many streets in North London, particularly in conservation areas and dense terraced housing, have restricted parking, narrow access, or controlled hours for skips and deliveries. Ask your builder how materials will be brought in, where waste will be stored, and whether scaffolding or a skip licence will be needed from the council. Sorting this out before work starts avoids delays and unexpected costs partway through the project.
4. Decide where you will live during the work
For smaller jobs such as a bathroom refit, staying in the house is usually manageable with some disruption. For larger projects involving the kitchen, structural openings or a significant part of the ground floor, it is worth honestly assessing whether living through the work is realistic, particularly with young children or if anyone in the household works from home. Some clients choose to move out for the most disruptive phase and return once first fix and plastering are complete.
5. Get the design and specification right before work starts
Changing your mind about layout, fittings or finishes once work is underway is one of the most common causes of delay and cost increases. Spend time before the project starts agreeing the layout, sockets, lighting positions and key finishes, so your builder is working from a fixed specification rather than making decisions on the fly.
A practical pre-renovation checklist
- Get at least two or three fixed-price quotes from builders and compare like for like
- Confirm whether planning permission, building regulations or party wall notices are needed
- Agree a payment schedule tied to project stages, not upfront lump sums
- Check your buildings insurance covers the works, and ask your builder about their own insurance
- Plan storage for furniture and belongings that need to be moved out of the way
- Agree a realistic start and finish date in writing, with an understanding of how delays will be handled

Common questions
- How much contingency should I budget for a renovation?
- A contingency of ten to fifteen percent of the total project cost is sensible for most renovations, and more for older properties where hidden issues such as damp or structural problems are more likely to surface.
- Do I need to move out during a renovation?
- It depends on the scope of work. Smaller projects like a bathroom refit are usually manageable while living in the house, but larger structural works affecting the kitchen or main living areas may be easier to manage if you can relocate temporarily.
- What is a party wall notice and when do I need one?
- A party wall notice is a legal requirement when planned work affects a shared wall, boundary, or nearby structure belonging to a neighbour, common in terraced housing. It must be served before certain types of building work begin, and your builder or a surveyor can advise on whether it applies to your project.
