Handyman- 15 Aug 2026
They were hired to build a Wendy house with instructions and complained about the instructions, said it was a lot of work and didn’t complete the roof properly. It would have been better if they said they never did it before or said they didn’t understand the instructions. Overall poor communication and overcharged

We have worked with Alex and his team at Swift Conversions Ltd twice now—first for a house extension and then for a loft conversion and general refurbishment —and we wouldn’t hesitate to choose them again for our next project. From the moment we received the quote to the final completion, Alex was incredibly communicative, reliable, and always had a can-do attitude. Despite the challenges of fluctuating prices in the market, he delivered the project within budget and stayed true to his word. His professionalism and trustworthiness are second to none. If you’re looking for a builder you can rely on 100%, Alex is the one to go to. Highly recommended!

Roy and his Son did a great job on my kitchen. They were polite and communicative and did what he said he would do. Roy took over this job from a previous bad builder and nothing phased him. He was able to complete my kitchen to my vision and I am very pleased with his job. I will recommend Roy for Kitchen building works and renovations.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Kitchen Fitting- 9 Aug 2026
Andy was brilliant from start to finish. Friendly, professional, very knowledgeable and willing to offer advice (but also happy to do it the customers way!). We had a large kitchen fitted with appliances and there were the usual “adjustments” off plan required -Andy did them without making a fuss. I would happily recommend Andy to a friend for kitchen fitting.

Questions to ask local loft conversion companies in Welling

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 Welling?

A local loft conversion company in Welling 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 Welling 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 Welling 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 Welling

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 Welling before agreeing to start the work.

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

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