I recently hired LLC Projects Limited to refurbish my ground floor and add a new bathroom, and I couldn’t be happier with the results. From start to finish, the team was professional, reliable, and truly cared about delivering quality work. The new bathroom looks amazing, and the ground floor transformation exceeded my expectations. Communication was great throughout, and they kept everything on track and tidy. The crew was friendly, and they handled any concerns I had quickly. I’d definitely recommend LLC Projects Limited for any home improvement work—they’ve earned my trust, and I’ll be calling them again for future projects

Loft Conversion- 2 Jul 2016
Top finish were ultimately hired to conduct this work. There was admittedly some job creep in this project. Alan came round and discussed our intentions and suggested a possible route forward. An architect (Red Squirrel Architects) was independently retained by us to work with the Top Finish team to deliver a Dormer conversion reorganization and significant structural works for a side return extension and installation of a new kitchen (13 steels were inserted and a sewer had to be bridge over, with permission) The job was completed to a high specification, particularly given some of the problems thrown at the team when dealing with a 150yr old property. I think it's important to understand that when undertaking jobs of this scale, and if you are planning to live in the property as we did, then you are effectively living with the team you chose. To that avail- ALL of the top finish team were always considerate and a pleasure to be around and happy to fix any concerns rapidly as required. I wish Alan and his team all the best going forward and I would recommend meeting Alan and including him in your shortlist for any job - large or small.

Loft Conversion- 1 Apr 2022
What can i say, great guys to work with. Came round and quoted as planned. Good competitive pricing. Completed the job better than planned. Always advised and tried to improve on the plans, really have good attention to detail and take so much pride in their work. Job completed bang on time. Never had a issue whatsoever. Arrived on time, good communication and nothing was to much for them. Will definitely be doing my extension next. New to my builder so they dont have much reviews, but not to worry just have a look at their instagram which they update DAILY. You can literally watch them building.. Thanks lads

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

Restoration & Refurbishment- 18 Nov 2017
We were initially very impressed with Vilmos's work and communications with him. However, he has not completed the work and has been uncontactable since end Aug 2017. Vilmos identified and fixed a lot of errors made by a previous builder such as leaks in the bathrooms. He carried out works as requested by building control and as far as we can see these works were completed. We were especially happy with our communications with him as we were based overseas. The final step is for Vilmos to meet with the building control and get the building works signed off. However, Vilmos has suddenly become uncontactable via phone and email and has not contacted building control to carry out the final step.

Loft Conversion- 6 Mar 2018
Loft conversion. We were delighted with Peter and his team. We were impressed with the hard work shown by all of the builders on site. We were particularly impressed by the speed(2 months) and quality of the work at a competitive price. There was surprisingly limited disruption to family life. Most access was from outside with toilet facilities also located outside. As with all big builds issues will occur. These issues were dealt with switly in a professional manner. We would highly recommend Peter and his team

Questions to ask local loft conversion companies in Penge

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 Penge?

A local loft conversion company in Penge 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 Penge 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 Penge 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 Penge

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 Penge before agreeing to start the work.

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

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 Penge 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 Penge loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
