Bathroom Fitting- 7 Jun 2026
Excellent service and outstanding workmanship! I recently had my bathroom renovated by this company and I couldn't be happier with the results. From start to finish, they were absolutely professional in every way. The quality of their work is truly perfect - they paid such close attention to detail and did an amazing job with everything. What's more, the price they quoted me was very reasonable and they stuck to it without any hidden costs or surprises. The whole process was smooth, efficient and stress-free. I would highly recommend them to anyone looking for building services - they really are top class and provide excellent value for money. Thank you for such a fantastic job! To Abdullah and his team.

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!

Restoration & Refurbishment- 4 Jan 2026
At the outset, Harry and his partner are good people. However, the job was not completed to a professional standard. Grout has started coming off from between the tiles leaving gaps that water can pass through, the door hinge was not properly fitted leaving a door that will not close, the radiator pipe clips were not fitted, tile trims are not flush with rest of the wall, shelves were fitted on top of old broken wood. And the worst part is that Harry did not turn up even after confirming a date to come back and fix the missing parts. I paid him extra for all the additional jobs, even though certain items from the contract were not done ( for e.g. replacing the bathtub panel ). They have multiple jobs ongoing at the same time and struggles to stick to schedule. If you get them I would advise not paying everything upfront and making sure contract is signed only after it is made sure that they would stick to schedule. I struggled to get them to commit to a date and stick to it.

Groundwork & Foundations- 9 Oct 2017
Excellent work, and I'm very happy with my concrete plinth. The work was done on time and to schedule. All preparatory stuff was sorted, i.e. skip, license etc and after completion the site was left spotless. And all this for a very competitive price. Can't recommend these lovely guys highly enough and will certainly use them again.

Questions to ask local loft conversion companies in Northolt

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 Northolt?

A local loft conversion company in Northolt 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 Northolt 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 Northolt 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 Northolt

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 Northolt before agreeing to start the work.

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

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