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.

Roofing (Flat)- 2 Aug 2023
Stay clear of this person as he is not experienced builder and do not fulfill his commitments after taking money. Don't hire this tradesman unless you want someone not to turn up on agreed date and time or you want to chase him again and again without him picking up your phone calls or answering them.. My garden shed was leaking from the side. Amarjeet recommended to put new flashing on the garden shed roof to fix it. However, after putting flashing, the garden shed continued to leak from the same area he had put the flashing. He said this time the cause of leak were the joints which he failed to look into earlier. So, he fixed that. After second fix, the shed again leaked, this time directly under the flashing he had put. When I asked him to fix it, he refused saying that the issue is with the joints and not the flashing. I told him that I had hired him to fix the water leak and not the flashing or joints. I even said that I will pay him if the issue is different. After ringing him several times and then agreeing a date and time with him, he didn't turn up. He is not a professional or experienced builder. Having now spoken to another builder, they suggested that the issue is that the water is somehow going under the flashing he had put. There is a bigger problem of the water standing on the roof which needs to be fixed first and which this builder failed to notice. Unfortunately, I will have to pay another builder to complete his work!

Bathroom Fitting- 7 Jul 2026
This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook. The other person didn’t do work properly and left the bathroom unfunctional after three months. Very bad experience and they took more money when they buy materials. Its disaster

Latest review:
Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Questions to ask local loft conversion companies in Tadworth

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 Tadworth?

A local loft conversion company in Tadworth 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 Tadworth 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 Tadworth 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 Tadworth

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 Tadworth before agreeing to start the work.

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

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