Damp and cold garage floors
Garage slabs sit below house floor level. Without proper damp proofing, insulation and ventilation, converted space becomes cold, musty and unusable.
Garage Conversions
Turn unused garage space into a valuable living area.
A cost-effective way to add living space without extending your footprint. Popular for home offices, bedrooms and playrooms.
What's included
- Damp proofing and insulation
- New window and external door if required
- Electrical installation and heating
- Plastering, decoration and flooring
- Building Control approval and completion certificates
- Tied in cleanly with the rest of your property
Thermal performance, ventilation and fire escape requirements are covered as part of our managed Building Control process.
The challenge
Problems homeowners face
Garage conversions look straightforward. In practice, these are the issues homeowners hit when the job isn't managed properly.
Quotes that skip Building Control
Fire separation, escape routes, thermal standards and electrical certification are not optional. Cutting corners creates problems when you sell or remortgage.
Poor tie-in to the main house
Different floor levels, awkward door openings and visible joins make conversions feel like an afterthought rather than part of your home.
Losing practical storage
Converting without thinking about remaining storage, access or services leaves homeowners regretting the layout within months.
No single project manager
Electrician, plasterer, carpenter and builder coordinated separately means delays, gaps in quality and nobody accountable.
Our approach
How we solve them
We convert garages properly: surveyed first, documented throughout, signed off through Building Control.
Survey-first feasibility
We assess structure, floor levels, head height, services and damp conditions before quoting. No guesswork.
Full thermal upgrade
Insulation, damp proofing and ventilation designed to current standards so the room performs like the rest of your home.
Seamless integration
New openings, floor transitions and finishes tied in cleanly with existing rooms.
Building Control managed
All submissions, inspections and completion certificates handled as part of our service.
One company delivery
Electrics, plastering, heating, flooring and decoration under one programme and one point of contact.

Regulations
Planning & Building Control
Planning Permission for Garage Conversions
Most garage conversions fall within Permitted Development if the footprint does not increase. Change of use rules and local constraints still apply.
- External appearance changes may need approval in conservation areas
- Creating a separate dwelling may require full planning permission
- We verify status at your free survey before you commit
- Lawful Development Certificates recommended when selling
Permitted Development for Garages
Converting an existing garage to living space often qualifies as Permitted Development, provided you are not increasing the building footprint.
- Must not extend beyond the original garage envelope
- Article 4 directions can remove PD rights on some estates
- Listed buildings and conservation areas have stricter rules
- We confirm PD status at survey
Building Regulations for Garage Conversions
All garage conversions must meet Building Regulations for thermal performance, fire safety, ventilation and electrical safety.
- Fire separation from garage if partially retained
- Minimum ceiling height and escape route requirements
- Part L insulation standards for walls, floor and roof
- Part P electrical certification on completion
- Completion certificate before handover
Avoid costly errors
Common mistakes to avoid
Learn from the errors we see homeowners make — so your project runs smoothly from day one.
Skipping the damp survey
Garage floors and walls often hold moisture. Converting without addressing this leads to expensive remedial work later.
Ignoring head height
Minimum comfortable ceiling height matters. We assess structure and floor build-up at survey.
Underspecifying electrics
Garage circuits rarely suit living space loads. Consumer unit upgrades are often required.
No Building Control sign-off
Unregistered work causes problems on sale. We coordinate sign-off before handover.

Frequently Asked Questions
Will I lose my parking space?
The internal space converts to living area. If you need to retain parking, we can discuss partial conversions or alternative layouts at survey.
Does a garage conversion need planning permission?
Most garage conversions are permitted development, but change of use rules apply if the property is in a conservation area or has restrictions. We verify this at survey.
How much value does a garage conversion add?
A well-executed conversion typically adds 10–20% to usable floor space. We focus on quality that adds genuine long-term value.

Feeling Like Just Another Customer
Customer Completion Gift
A small thank you for choosing us.
A fantastic job done on my property by Kyle and team. Highly recommend them for all roofing and guttering jobs. Also would like to add the great communication from start to finish. Thank you!
Kyle and the team did a great job today of cleaning my garage roof from moss and then painting a polymer waterproof coating onto the roof. The manufacturers 10 year guarantee for a single layer makes it an easy choice for fixing water ingress into a garage. Time will tell, but I have high expectations. All the rubbish generated was taken away so very pleased.
Kyle and his team at Quality Roofing were great, punctual, communicative, and reasonably priced. They removed our old solar heating panel, replaced the felt and tiles underneath, and disposed of the panel, all in under 90 minutes. Great service from a reliable team.
Kyle arrived quickly to look at a problem we had with an old Velux. He quickly set about repairing it and it is now working fine. We really appreciate his quick service. Highly recommended.
