“I selected J Highgate from Checkatrade based on their reviews and I couldn't have made a better choice. This was for a ground floor extension, new kitchen and other refurbishment needed to a fairly run-down house we purchased. From the start right throughout the around 10 weeks duration of the works, the entire team were simply superb and a delight to work with. The team were proactive in coming up with ideas for consideration when some re-thinking became necessary at critical parts of the works. The final outcome and quality of work was 10/10. High commendations all round.”

Loft conversions in KT4: Homeowners vs renters
If you own your home:
- You’re responsible for planning, permissions, and hiring.
- Check if you need planning permission; many lofts fall under permitted development, but not all.
- Building regulations always apply. A loft conversion without sign-off could cause issues later (including invalidating home insurance).
If you rent:
- You can’t carry out major work like a loft conversion.
- Speak to your landlord if you notice issues in the loft space (leaks, insulation problems etc.).
- If you spot an unregulated loft conversion, flag it with your landlord or letting agent.
