BuiltFlix 360 is a family-run construction company and building contractor covering London and the Home Counties. Builders, gas engineers, electricians and decorators in house, working to one programme and one fixed price.
We started in 2009 with one van, two bricklayers and a rule we have never dropped: finish what you start, and leave the place cleaner than you found it.
Sixteen years later we are a team of 34 covering everything from a leaking radiator to a two-storey rear extension. Large enough to hold a build programme together, small enough that the person who prices your job is the person you call when you have a question about it.
Every project gets one named project manager, a written schedule you can hold us to, and a price that does not move unless you ask for something new. That is the whole business model.
The six things clients tell us made the difference, in their words rather than ours.
Itemised written quotes with a fixed total. No day-rate drift, no vague provisional sums, no invoice you have not seen coming.
A named project manager runs your job and sends a short written progress update at the end of every week you are on site.
Floors sheeted, dust screens up, skips managed and a full professional clean before we hand the keys back to you.
Gas Safe engineers, NICEIC electricians and time-served carpenters. We rarely subcontract, and never without vetting.
£5m public liability insurance and a 12-month workmanship guarantee on everything we install, with certificates at handover.
Programmes are built with float, so the finish date we give you in week one is the finish date you get in week sixteen.
Twelve trades, one contractor, one invoice. Every service below is delivered by our own team and carries the same guarantee.
Ground-up builds, structural alterations, steelwork and underpinning, managed by experienced building contractors from foundations to sign-off.
Full property refurbishment for homeowners, landlords and investors, from a tired flat brought back to lettable standard to a complete period restoration.
Single storey, double storey, side return and wrap-around house extensions, including drawings, structural calculations and planning support.
Kitchen renovation from design to the final silicone bead, with plumbing, electrics, tiling and worktop templating handled by our own trades.
Bathroom renovation, wet rooms and en suites, fully tanked and tiled, typically completed in seven to ten working days.

A disused garage plot developed into two energy-efficient units, delivered from groundworks to handover.
Reviews collected on completion from homeowners and landlords across London.
We had been let down twice before we found BuiltFlix 360. They quoted in four days, started when they said they would and finished our side return two days early. The final invoice matched the quote to the pound.
I manage eleven rental properties and BuiltFlix 360 now handle all of them. Response times are honest, the reporting is clear and my tenants actually compliment the workmen.
The quote was the most detailed of the five we got, and the only one that explained why things cost what they cost. That is why we chose them, and they were right about every line of it.
If yours is not here, ask us directly. We answer messages within one working day.
In London, single storey extensions generally land between £2,200 and £3,000 per square metre depending on structure, glazing and finish level. A side return typically runs £55,000 to £90,000 all in. We give you a fixed figure after the site visit rather than a range.
Many extensions and loft conversions fall under permitted development, which means no planning application. We check your property against the current rules at the site visit and tell you straight away which route you are on. If you do need permission, we prepare and submit the application for you.
A bathroom takes seven to ten working days, a kitchen two to three weeks, a loft conversion six to nine weeks and a single storey extension ten to sixteen weeks. You get a week-by-week programme with your quote, and a written update every Friday while we are on site.
Yes. The price only changes if you ask for something that was not in the specification, or if we open up a floor and find something genuinely hidden, such as failed drainage. In that case you get a written variation with costs before any extra work starts. Nothing is added after the fact.
For extensions, loft conversions and single-room renovations, almost always. We set up dust screens, protect floors and routes, and keep at least one bathroom and the kitchen usable wherever possible. For full refurbishments with a rewire, most clients move out for two to three weeks.
Payments are tied to completed stages, never to time passing. Typically a deposit to secure materials and dates, then stage payments as agreed milestones are signed off, with the final balance due after the handover walkaround and snag list are complete.
£5m public liability insurance, a 12-month workmanship guarantee on everything we install, and manufacturer warranties passed straight to you. Boilers are registered with Gas Safe and electrical work is certified through NICEIC, with certificates handed over at completion.
All Greater London postcodes plus Surrey, Kent, Essex and Hertfordshire within roughly an hour of our Northolt base. For maintenance contracts we work inside the M25. If you are just outside, call us anyway and we will tell you honestly whether we can service the job properly.
