We recently completed a full house refurbishment including a 4-metre rear extension, dormer loft conversion, and complete interior renovation with ALMO Property Group—and I genuinely couldn’t recommend them more highly. From the very beginning, the team managed everything seamlessly, from planning and design through to execution. What could have been an incredibly stressful process was made smooth, organised, and surprisingly enjoyable thanks to their professionalism, communication, and attention to detail. The quality of workmanship throughout the project has been exceptional. Every stage was handled with care, precision, and a clear commitment to delivering a high-end finish. The team were reliable, efficient, and always kept us informed, which gave us real peace of mind. A special mention has to go to Ameer, who was absolutely outstanding from start to finish. His dedication, responsiveness, and willingness to go above and beyond made a huge difference. He was always on hand to answer questions, offer solutions, and ensure everything ran perfectly. ALMO Property Group have completely transformed our house into a beautiful home, and we are beyond happy with the results. If you’re looking for a trustworthy, skilled, and professional team, I would highly recommend them.

Conversions - General- 22 Feb 2020
Quoted £500 to remove small kitchen wall (<1m wide), make adjacent wall good, and move light switch. Removed wall, moved switch, and kindly moved fridge. Said he'd return to make wall good. On two occasions I arranged to WFH and he failed to show up or let me know. On multiple occasions he said he might be able to do a day but then didn't confirm. He did come by when we weren't in one day to drop wood off to cover wall gaps. One day I arranged for our dog walker to be in at 1. She waited until 3. I messaged Daniel later to ask what happened. He apparently came at 1.20 and waited for 15 mins. I believe he turned up and our dog walker didn't hear door but it's unlikely he tried to knock multiple times over 15 mins, as she was listening for him. Agreed he would finish work in new year. In Jan again failed to confirm days/times on multiple occasions. Finally agreed noon on a Sat. Failed to show up/respond to messages. Eventually got through to him - said his phone was broken. No explanation re why he didn't show up. Agreed he'd come the next Sat but no show again. No response to message or to later one asking if he planned to finish the job. Received a missed call but nothing further. I've left it a month as hoped he would get in contact. It's clear he has run off with £500, leaving giant holes in wall. I work long hours and weekends are precious. I have no patience for someone who has no respect for my free time, or for fact it's not possible to WFH all the time.

Carpentry- 17 Oct 2025
Nico did a fantastic job. The new wardrobe doors look amazing and fit perfectly after adjusting to fit the older door frames which had settled and moved slightly out of alignment over the years. Better than the original ones. The bedroom doors were replaced and fitted to open to the correct side of the rooms. The broken stair was expertly cut and fitted and matched perfectly to the rest of the stariway. Very solid and completely squeek free. Built to last a very long time. Nico is very reliable, dependable and highly skilled. I highly recommend him for any carpentry work needed.

Gas Work- 7 May 2024
Florin has done a great job to replace my gas system boiler. He worked hard to finish the job in one day, in fact stayed late evening to make sure the job was completed. He registered the boiler, provided the building reg and Lanlord certificate. I will recommend him based on my experience and will use him again in future.

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

Gavin and Luke built a single storey extension for us. It was quite complex and they had to remove several internal and external walls. They are very nice people to work with, genuine and honest, amenable. They were here for 9 months doing our work and we are thoroughly happy with them. They are very good - I would certainly recommend them.

Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

Questions to ask local loft conversion companies in Iver

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 Iver?

A local loft conversion company in Iver 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 Iver 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 Iver 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 Iver

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 Iver before agreeing to start the work.

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

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