Kitchen Extensions, Loft Conversions & Full Renovations in South East London
One project manager. One fixed price. 100+ projects completed across 25 boroughs.
NICEIC, FENSA and CHAS accredited. Building Control sign-off included. Free site visit across 25 London boroughs.
Most renovations go wrong for the same three reasons.
You hire an architect. The architect hands you a design. You tender it to three builders. One is too cheap, one is too expensive, one never replies. You pick the middle one. They bring their own electrician, plumber and plasterer, none of whom work for them full time.
When something goes wrong, everyone blames everyone else. The price creeps up. The timeline slips. You spend your weekends chasing tradesmen.
That is the standard way to renovate a house in London. It is why most homeowners finish their project swearing they will never do another one.
We built All Well to be the opposite of that. One team on your project from the first site visit to the final Building Control sign-off. One price, agreed in writing before we start. One person on the phone every time you call.
Everything we do
We are a design-and-build contractor based in Anerley, SE20. We handle your project from the first conversation through to the last coat of paint. Every service below comes with the same fixed-price contract and the same single point of contact.

What you actually get when you hire us
Fixed price, in writing, before we start
The quote we give you at the free site visit is the quote you pay. Not "estimated", not "from", not "subject to discovery". Over 100 projects since 2020, zero surprise bills.
One person on the phone every time
When you call, you get Richard. Not a receptionist, not a different project manager each week. Richard manages every live project personally from the first site visit to the final sign-off.
The paperwork your solicitor will ask for
Every project comes with the full documentation pack: NICEIC electrical certificate, FENSA glazing registration, Building Control completion, structural calculations, and a workmanship warranty. Most builders do not hand this over. We put it in a folder.
How a project with us actually runs
Four stages, no surprises, one person managing every one of them.
Free 45-minute site visit
Richard comes to your property, looks at the space, talks through what you want, and explains what is and is not possible. No sales pitch. If your project is not a fit for us, he will tell you honestly and suggest alternatives.
Fixed-price quote in writing
Within 5 working days we send you an itemised quote. Every trade, every material, every fee. No TBC lines. If you want changes to the spec, we revise and reprice before any work begins.
Design, planning, and Building Control
If your project needs drawings, structural calculations, or planning permission, we handle it. If it does not (most do not), we still apply for a Lawful Development Certificate so you have written proof from the council.
Build, sign-off, paperwork
Richard runs the build and you get weekly progress updates. When we finish, Building Control signs the project off, we hand over every certificate, and we leave the site cleaner than we found it.
What most people ask before hiring us
How do I know you will not disappear halfway through the job like the last builder?
We are a registered limited company (No. 12721034) based at a fixed address in Anerley, SE20. We have 57+ Google reviews averaging 4.5 stars under our real business name. Richard has managed every project personally since 2020. Our contracts use stage payments tied to verifiable milestones, so you never pay for work that has not been done.
What if the quote goes up mid-project?
It will not, unless you change the scope or we uncover something genuinely hidden behind a wall. In both cases we quote the variation in writing and you sign it off before we proceed. Over 100 projects since 2020, our fixed-price contracts have held.
Do you handle planning permission and Building Control?
Yes, both are included in every project we take on. Most of our projects proceed under permitted development, and we apply for a Lawful Development Certificate so you have written proof. When full planning permission is needed, we handle the application. Building Control inspections, sign-off, and certificates are all managed by us.
How long will my project actually take?
The timelines on the service pages are realistic ranges based on our actual project data since 2020. A typical kitchen extension is 10 to 14 weeks from start on site. A bathroom is 2 to 4 weeks. A loft conversion is 6 to 10 weeks. The programme of works we send with your quote breaks it down week by week.
