Frequently Asked Questions
Do I need planning permission for a garage conversion?
Most garage conversions fall under permitted development rights so planning permission is rarely required. We confirm this during your survey and manage any applications if needed.
How long does a garage conversion take?
Most single garage conversions take around two to three weeks to complete. We provide a clear schedule so you know what to expect.
Can you convert a detached or double garage?
Yes. We convert single, double, part and detached garages into comfortable, practical rooms that add real value to your property.
Is insulation included in the conversion?
Yes. Floors, walls and ceilings are insulated to meet energy efficiency standards so the space stays warm and comfortable all year round.
Do I receive official certification?
Yes. We liaise with Building Control and ensure your conversion is inspected, approved and certified on completion.

From day one, everything just worked like clockwork. Mo at Phoenix Garage Conversions kept in touch regularly, the lads were polite and the space looks brilliant.
They even brought their own dust sheets and vacuumed every evening. It’s now a quiet study room and the difference in noise and warmth is night and day.

Phoenix Garage Conversions were absolutely spot on. We had a fairly big job turning our double garage into a guest suite for when family stay over.
Mo managed everything brilliantly, from the first meeting to the final clean-up. The team worked hard, kept the area tidy and were friendly with our kids too. The space feels like a natural part of the house now. Couldn’t fault the service at any stage.

After speaking to a few firms we chose Phoenix and they were brilliant. Mo helped with ideas and suggested a better layout than we’d originally thought.
They handled building control and everything ran smoothly. We’ve now got a stunning snug area for reading and relaxing. The space is lovely and we’ve already recommended them to my sister!

Phoenix Garage Conversions were fantastic. Mo explained everything clearly and the lads were tidy and respectful throughout.
The garage is now a lovely snug room that we actually want to spend time in. Wouldn’t hesitate to recommend them to anyone thinking of doing similar.

We’d been putting this job off for ages thinking it’d be too disruptive but Phoenix made it simple. Mo came out, gave a clear quote and stuck to it.
The work was tidy, professional and finished quicker than we thought. We’ve now got a peaceful room to relax in and honestly wish we’d done it years ago.

Honestly can’t fault them. Mo was straight-talking, the team were polite and kept the drive clean.
Phoenix Garage Conversions finished ahead of time and didn’t charge a penny more than agreed. The room’s now a gym and it’s been used every day since. So glad we did it when we did.

We saw Phoenix recommended on a local group and booked a quote. Mo arrived on time, measured up and gave us a fair price.
They stuck to it, no hidden extras. The conversion is now a snug family lounge and it’s totally changed how we relax in the evenings. The build was fast, tidy and stress-free — would 100% recommend.

We were after a quiet retreat space and Phoenix Garage Conversions nailed it. The team worked quickly, tidily and treated our place with respect.
Mo gave updates without us needing to ask. Even the rubbish was removed without hassle. We’re delighted with the final result.

We used Phoenix Garage Conversions in April to create a small annexe for my mum. Mo was brilliant throughout — always respectful and explained each step.
The work was tidy, efficient and finished on time. It’s now warm, quiet and looks fantastic. She absolutely loves it. We’re glad we trusted them with it.

We’d wanted to convert our garage for ages but didn’t know where to start. Mo came round and instantly put our minds at ease.
He listened to what we needed and talked us through every step. The Phoenix lads were polite, tidy and hardworking. We’ve now got a warm, bright office that feels nothing like the old space. Genuinely chuffed with the result.

Phoenix Garage Conversions did a cracking job. They converted our garage into a warm guest bedroom with an en-suite and handled everything including the electrics.
Mo was easy to reach and actually returned calls which I’ve learned not to expect from trades. Everything was done exactly as quoted.

Really professional, tidy and helpful. Have used them for various home improvement projects and they’re always a pleasure to deal with.
Happy to recommend.

We chose Phoenix after seeing a neighbour’s conversion and I’m so glad we did. Mo was easy to deal with, gave us proper advice and stayed in touch the whole way through.
The team built us a home office with plenty of natural light, and it’s now the best room in the house. They worked quickly, cleaned up daily and the quality of the finish is top drawer. Highly recommended.
