Conversions - General- 7 Oct 2022
Luca and his team were superb all the way through and handled the job brilliantly. From the initial quote, Luca was warm and friendly and gave me every confidence in the project. My precise needs and requirements were evaluated before anything happened, and Luca came up with some great ideas to maximise the result of the build. The whole process was smooth from start to finish with regular updates on progress. The final result was outstanding, I couldn't be any happier! Excellent quality workmanship and nothing was too much trouble. Luca's team are so good to work with, Walter was an absolute pleasure and was incredibly kind and respectful (I have a young daughter and nothing noisy was done during nap times!). The project cost stayed exactly to quote too. I hope to work with GS Build & Design again in the future. Thank you very much for everything!

Kitchen Fitting- 16 Feb 2026
Deli couldn't do my job due to an emergency that required him to travel. However, I found him very polite and helpful before he had to leave.

Extensions- 1 Jun 2020
We choose Surrey Build & Maintain because we felt like Dan and the team really listened to our vision for the extension and shared the desire to produce something that would be an amazing improvement to our house. As with any build, there were many hurdles to overcome. Dan and the team were always there on hand to deal with challenges and overcome them in a professional and experienced fashion. We really felt that Dan was on our side and was able to find numerous ways to improve the project as well as saving money by assisting to redesign the structural plans as they were unnecessarily overzealous. The team was punctual and hard-working, often working on weekends to increase the rate of construction. We stayed at the house during the build and Dan made every effort to make the impact on us as minimal as possible, laying dust sheets, cleaning up each day and keeping a temporary kitchen available to us during the project. We took advice on key features like doors and windows from Dan during the build and absolutely loved his design input. The end result is fantastic and we barely use any other room in the house! Since Dan began the kitchen extension we have also employed Surrey Build to overhaul our bathroom as well. Highly recommended!

Loft Conversion- 15 Aug 2024
Vic’s quote was extremely competitive. He and his team were very punctual, clean and tidy. The speed they work is phenomenal so much so the job was finished ahead of schedule. I was kept informed at all times and no extra work was taken on without my consultation. The end result is beyond our expectations. I would highly recommend Vic and his team.

Extensions- 20 Feb 2020
Decent builders but with extremely poor communication skills. First the good points: 1. They are good at internal finishes 2. They create and use a Statement of Work (SOW) to track all costs of the project, so there were no major surprises in the project 3. They are friendly and hard workers - who arrive on time Gotbath UK Ltd used subcontractors to build us a 6 meter rear extension. Although they had an in-house architect, they did not know the law around boundaries which resulted in a conflict with our neighbours. After spending hundreds on hiring a boundary surveyor, the initial wall had to be re-built within our boundary. Gotbath did not take any responsibility for the wrong information they provided to us regarding boundaries and charged us for the rebuild. When discussing how to finish the inside of the extension, GotBath were extremely slow in ordering supplies and in general responding to us, so we took matters into our own hands and ordered materials ourselves which were removed from the SOW provided to us. At the end of the project, finishes took a long time and required constant chasing. Final gas, electrical and warranty documents took a long time to reach us and required a lot of chasing too. I have very little confidence that GotBath will honour the warranty document they have provided to us. It's a shame because I can see GotBath have a lot of potential as a builder. However, their lack of communication has really let them down.

Loft Conversion- 24 Jul 2021
I have to say I was very impressed with Axe from the outset. Ed the project manager clearly knew what he was talking about and was able to come up with suggestions and guidance whenever a decision was needed. He provided an up-front itemised quote, and this was stuck to. The team of workmen led by Avram did an excellent job and I am very happy with the finished product. Avram in particular was a superstar: high quality workmanship, creative solutions to problems, hard-working and most importantly he takes a pride in his work as if it were his own house. Plus, he noticed a tiny leak in the roof unrelated to the project which he fixed at no extra charge. Recommended - I would use them again.

Questions to ask local loft conversion companies in Greenford

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 Greenford?

A local loft conversion company in Greenford 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 Greenford 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 Greenford 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 Greenford

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 Greenford before agreeing to start the work.

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

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