You NEED Housi on your project, they took the stress out of our renovation!! We would highly recommend! We got in touch with Housi to help with ideas to renovate a new property I was buying. Holly from Housi helped us with architectural and industry advise throughout the process even before starting full design services which helped me understand my budget more and where items from the survey and my design ideas could overlap. As I was trying to limit costs, Housi helped develop a phased approach to the works as well as assessing options to have a self contained rental unit to bring in income to pay for the final works later. Overall, Holly helped us find minimal abortive works whilst trying to maximise value and functionality. As well as design strategy, she helped us submit a licence to alter application as we found out the house was under a covenant agreement, and managed the project through tender also - meeting with builders and getting quotes. Most importantly, she was able to advise us where builders may be overcharging so we could assess the right builders for us. Working with Housi really made a difference to our project by helping us understand the different stages of a renovation. Holly offered so much more advice and reassurance than any previous professionals we had worked with on our last house and even helped us source re-claimed steel as we wanted to be as circular as possible.

We have known and worked with Joe for the last 6 years. He has recently built a ground floor kitchen extension and created a utility area and downstairs cloakroom for us. His ability to communicate each phase of the build’s requirements is brilliant. His craftsmanship is impressive. He has the ability to turn ideas into reality. Joe is a highly skilled plumber and electrician too which is hugely advantageous. He is professional and easy to have in your home. I can’t recommend Joe highly enough.

I had ongoing problem with my heating and hot water system, which was quite complicated.I contacted several well-known companies and I have spent a considerable amount of money, but none of them were able to identify or fix it . A friend recommended Mansour from heat input plumbers ,and I am very happy he did. Mansour spent almost half of a day carefully diagnosing the system,and successfully fixed the problem that others could not. I deliberately waited some time before writing this review to make sure everything working correctly. I am pleased to say that heating and hot water system has been operating perfectly ever since. Mansour is knowledgeable, professional,patient and clearly takes pride in his work. I extremely happy with the service and recommend him to anyone who need expert help with heating,boiler and plumbing in central London. Thank you Mansour,for a fantastic job

Bathroom Fitting- 28 May 2025
I am extremely happy with the job Isac has done. We are so very lucky to have found Isac to do our home. At the time of the works we were expecting a baby and Isac worked night and day to make sure our home was ready in time for our sons arrival. Without him we would have been screwed. Isac’s work is extremely professional. He has high standards and is very skilled. He’s honest, direct and respectful. I now consider Isac as a friend. He’s come back a few times since the works to check in and is always on the phone is you have any follow up queries. I would recommend Isac to anyone who has work they needed done. Thank you Isac!!!

Restoration & Refurbishment- 24 Apr 2019
I hired Dursun Altun and his team for a full refurb of 3 bed house. His business co-ordinator Ayse was helpful throughout the whole process and listened to the design requirements we had. Dursun provided full new plumbing and new boiler and all new electrical work. We had all our windows and doors replaced and are happy with the work done. His team fitted new bathroom, shower, toilet and also the kitchen. They also did some carpentry and provided shelves and doors for closets. His team decorated/painted and cleared up at the end of the job making sure it was all left clean and tidy. They did a good job and delivered on time! Dursun and Ayse made sure we were happy with the job and were lovely to work with. The job was done to a good standard and I would recommend them.

Questions to ask local loft conversion companies in Southgate

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Southgate?

A local loft conversion company in Southgate will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Southgate should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Southgate loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Southgate

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Southgate before agreeing to start the work.

Do I need planning permission for a loft conversion in Southgate?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Southgate loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Southgate loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
