Extensions- 25 Aug 2020
I did my due diligence on Vullcan, but things went downhill. After a week i got a pre-tax invoice for £3000 for a more "complex" drainage system which was already completed, this was the start of them trying to get around contract items and look for every way possible to charge extra fees which i can’t go through in the word limit here. When that dint work they refused to do the work. e.g. they literally installed a tempered glass sheet, with liquid glue on my roof and stated to me that this was a "roof window". I had to show them buildings regulations that this was unacceptable and illegal especially when our contract said it has to be a VELUX ROOF WINDOW! Promised a 6-8 week completion, this is 9 months later. I had now paid about 90% of the original bill and 100% of additional costs. The final payment was due after completion and a 2 week snagging period. But the demand for payments started, with threats to sue. This was laughable as they hadn't completed the job. •The roof was leaking •Electrical issues with the fuse box and multiple light /electrical points •Outstanding items •The buildings controls company stated they would not be able to sign off on the building work because of outstanding issues, which I wouldn’t have even known as they lied stating they HAD the certificate. I agreed to send a FULL payment to an escrow company and pay HALF of the costs so they can complete and fix safety issues but they refused! Shameful experience.

Extensions- 17 Apr 2019
My extention was left incomplete by a incompetent builder, I had plenty builders coming around for quotes until I decided to go with Peter & Chris after receiving their detailed quote with everything explained in blank and white. I am extremely happy with my choice, as they did a great job finishing the project on time and most importantly great finishes. Peter has an amazing interior design taste, I would definitely recommend picking his brains, Chris on the other hand is very experienced and knowledgeable in building, both work very well together as well as his labourers are very respectful and hardworking. I recommend Peter & Chris to anyone who wants a stress free project. An above and beyond service !

We used Vector Living as they were recommended to us by a friend. We were looking for a company to do our fairly large extension and loft conversion. We were nervous about finding a reputable builder as we had heard horror stories in the past. However, from the very start Ash was highly professional and explained the whole process step by step and put us at ease. He provided us with various options we hadn’t considered with not only saved a bit of money but also time. We did encounter unforeseen issues but this is where Vector Living made the difference, they always found a workable option for us. The process of construction was also smooth, always on time and finished to a very high level. We are extremely happy with Vector Living and would highly recommend them. If we ever decide to do a build again will be using them.

Restoration & Refurbishment- 6 Oct 2025
Rich and the team have done a fantastic job completing my kitchen and hallway renovation. His team guided me the whole process and were great communicators. No problem was too big or small to handle. There were some issues through the job (due to the initial poor design of the kitchen when it was first built) but the team were quick to resolve this professionally. I would not hesitate for a second to recommend Lux Contracts. Next year, I will be booking them for the rest of the flat! I’m happy to be contacted by prospective customers if any further information is needed. Rhys Gallagher

Questions to ask local loft conversion companies in Stockwell

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 Stockwell?

A local loft conversion company in Stockwell 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 Stockwell 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 Stockwell 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 Stockwell

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 Stockwell before agreeing to start the work.

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

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