Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

Loft Conversion- 30 Aug 2015
The job was split into separate parts for ease and Michael/MME took on the loft conversion piece. The conversion itself wasn't so straightforward as he was working with a previously created loft space with no building control sign off. Michael was great at every stage though, and work progressed very quickly. Attention to detail was fantastic - Michael identified ways to maximise space when quoting, and minor changes requested by me throughout the job were dealt with very efficiently. He even helped out here and there with some unrelated jobs going on in other areas of the property. I had a very specific design for the en-suite and Michael was very keen to make sure it was all done correctly. The property now has a fantastic loft space, additional bathroom, and most importantly is building control legal! I would have no hesitation in recommending Michael/MME to anyone else thinking of a loft conversion. It's very difficult picking a building company, but I felt I could trust Michael with the job from initial quote to final payment.

Loft Conversion- 26 Dec 2019
Working with Dil was a pleasure! From the the outset he was very helpful with calculating overall costs (over and above his costs) for the build to ensure everything had been catered for and was very thorough in checking that my ideas/plans were appropriate for the long term. It was through the initial discussion that some minor adjustments were made and for the better I believe, simple things like where the new Megaflow System should be placed. He was very quick and efficient in identifying where there may be issues upfront and has the right contacts to get things sorted to minimise problems further into the build. I had to get a new mains water pipe installed which to me was a a major job but he got it sorted very quickly through his contacts at a very reasonable cost. His team are very polite and they do a as good a job as possible to minimise impact on your daily living if like us you are living in the property during the process. Essentially a team of 3/4 guys who are capable of doing most things however Dil does call in specialist trade as and when needed to ensure the job gets done in a timely manner, for my build he called in roofers and certified plumbers for the boiler. Only negative is that you have to watch the silicone sealant finishing which is not the tidiest but a minor in the grand scheme of things and if you don’t like something you simply have to say and he will redo within reason. Overall a very happy customer

Latest review:
Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.

Questions to ask local loft conversion companies in Lambeth

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 Lambeth?

A local loft conversion company in Lambeth 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 Lambeth 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 Lambeth 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 Lambeth

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 Lambeth before agreeing to start the work.

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

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