Questions to Ask Before Hiring a Loft Conversion Company
What is the company’s experience with loft conversions specifically?
Look, not every builder out there really knows lofts. It's a different beast. So you gotta ask—how many have they actually done? And can they show you pictures? A crew that eats, sleeps, and breathes loft conversions? They get the weird structural stuff, the regs, how to get materials up three flights of stairs without losing their minds. A general handyman? Maybe not so much. Check their past work. Does it match your house? Your roof type? That matters.
Do you handle planning permission and building regulations?
Most of the time, you're fine under permitted development. But sometimes you're not. And that's a headache. So ask straight up: do you guys deal with the council or is that on me? Building regs though? Non-negotiable. Fire safety, insulation, electrics—the works. They need to handle the paperwork and get the inspectors in. If they shrug at this, run.
Can you provide a detailed written quotation and timeline?
Get it in writing. A proper breakdown. Materials, labour, scaffolding, windows, the stairs, plumbing, electrics. None of this "oh, about £25k" nonsense. You want a fixed price. And a timeline—when they start, key milestones, when they're done. If they can't commit to a schedule, or promise you the moon in two weeks? That's a red flag the size of a skip.
What warranties and insurance do you offer?
Insurance is a must. Public liability, employer's liability—ask to see it. And what about guarantees? A decent company will give you a 10-year structural warranty or something insurance-backed. That's your safety net if they go bust or something goes wrong years down the line. Don't skip this.
How do you manage disruption and site safety?
Honestly, a loft conversion is chaos. Noise, dust, your house turned upside down. So how do they plan to keep it from driving you insane? Ask about scaffolding safety, worker quals, where the crap goes. A pro crew keeps the site tidy, cleans up daily, and actually talks to you about what's happening. If they don't mention communication, that's a problem.
Data Table: Key Questions and Why They Matter
| Question | Why It Matters |
|---|---|
| How long have you been in business? | Been around a while? They're probably not going to vanish next week. |
| Can I speak to past clients? | Real people, real stories. Better than any five-star review. |
| Who will be my main point of contact? | One person to call. Saves a ton of confusion and delays. |
| Do you subcontract any work? | Subbies can be a mixed bag. Might mess with quality and who's accountable. |
| What happens if there is a problem? | Knowing how they handle complaints means things get fixed, not ignored. |
Checklist: Before Signing a Contract
- Make sure they're with a trade body—FMB, NHBC, TrustMark, something like that.
- Get at least three quotes. Don't just go with the first one.
- Read reviews on Checkatrade or Google. Real ones, not just the five-stars.
- Ask for proof of insurance. Check the date isn't about to expire.
- The contract needs a payment plan, start date, and finish date.
- Scope of work should list everything—carpentry, plumbing, electrics, plastering.
- Is scaffolding and skip hire in the price? Or is that extra?
- How do they handle changes? Extra costs? Get that in writing too.
Frequently Asked Questions
Do I need planning permission for a loft conversion?
Usually, no—if it's within size limits and not facing a road. But building regs are always needed. Check with your local council to be sure. The company should know this stuff inside out.
How long does a loft conversion take?
Four to eight weeks, give or take. A simple dormer? Maybe four. Something like a mansard? Six to eight, easy. Weather, materials, hidden problems—they can all slow things down.
Will my loft conversion add value to my home?
Yeah, a good one can bump value by 15–25%, especially with a bedroom and en-suite. But don't go overboard—spending more than you'll get back is a real risk. Talk to a local estate agent first.
What is the difference between a dormer and a mansard conversion?
A dormer sticks out from the roof slope, giving you headroom. A mansard basically rebuilds the whole roof—flat top, steep sides. Costs more but you get way more space. Common in terraced houses.
Do I need fire safety measures in my loft conversion?
Absolutely. Fire doors, smoke alarms, a proper escape route. If the loft's more than 4.5 metres up, you might need a protected staircase. The company has to follow Part B of building regs. No shortcuts.
“The cheapest quote is not always the best. A thorough vetting process saves you from costly mistakes and ensures your loft conversion is safe, legal, and adds genuine value to your home.”
