Bathroom Fitting- 2 Jan 2025
Extremely Disappinted with Planetium Construction- I hired Planetium for a 59k renovation job. Initially, the workmanship was acceptable only because I supervised closely and had them redo substandard work multiple times. However, before the job has been complete, I discovered already a roof leak in the master bedroom, direcly under the newly renovated bathroom. Despite my repeated requests, Planetium refused to take responsiblity or fix the issue. Just telling me need additional charges for the work. Worst still, Adrian the owner, demanded I pay the final balance of 1840 before they would address the GF heating which stopped working after they installed the new controller. When I reasonably refused to pay before they complete the job , Adrian swore at me over the phone the most offensive language. Furthermore, they promised to replace a new Miele microwave for the one they damaged during installation but now just walked away. Leaving me unresolved issues and additional repair cost!

Highly recommended. Work was done on budget and on time. Narcis and Levi always happy to help and listen to any queries and adapt as the job went on. Left the place clean at the end of each every day. We had a small leak under the sink after the job was finished which was sorted out promptly. The finish (painting/tiles etc) was of decent quality. Bathroom was completed 6 months ago and no problems since.

I had the pleasure of Charlie and Kurt coming to do some work for me at one of my properties as the place hadn’t been touched in years and needed some serious TLC! They had replaced the ceiling in the bathroom, redone the decking and refitted some appliances as well as repairing the pointing outside and redecorating the entire house. This was a big job as the house is old and had defects all over in awkward places but they made sure to complete all touch ups to ensure the finish was to a good standard. They even tidied up the garden and had replaced some benches I had outside for free which was very much appreciated. Definitely recommend them for any jobs locally big or small! Thanks again guys :)

Loft Conversion- 1 Aug 2025
Sami completed our loft conversion to a high standard, on time and within the agreed budget. He was respectful, supportive, and very knowledgeable. He offered helpful input and practical suggestions throughout the project. When I came up with ambitious design ideas that would have cost a fortune, he provided honest, pragmatic advice and suggested smart, cost-effective alternatives that saved us a lot of money. He communicated clearly, was easy to work with, and kept everything running smoothly. He also recommended trusted tradespeople when needed, all of whom did excellent work. In addition to the loft, Sami and his team completed other jobs around the house with the same high standard and care. I wouldn’t hesitate to recommend him — reliable, skilled, and genuinely committed to quality. A fantastic builder who takes pride in his work and delivers results you can trust. We’re absolutely delighted with everything he’s done.

Lukasz and his team built a lower floor kitchen extension and downstairs WC for my wife and I. From start to finish, they were extremely professional and helpful. They were the perfect builders for first time renovators such as ourselves, guiding us through difficult decisions, while sticking religiously to their timescales. They began with helping us scope out the design, adding useful insight and advice. They then set to work, making our vision a reality. Their work ethic was superb, and we were ecstatic with the level of craftmanship exhibited. Like any building project, there were unforeseen costs and issues, but these were always handled very fairly and efficiently by Lukasz and his team. We are over the moon with the end product! I would (and have) recommend Lukasz to anyone looking to undertake building work.

Questions to ask local loft conversion companies in Parsons Green

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 Parsons Green?

A local loft conversion company in Parsons Green 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 Parsons Green 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 Parsons Green 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 Parsons Green

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 Parsons Green before agreeing to start the work.

Do I need planning permission for a loft conversion in Parsons Green?

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