Frequently Asked Questions

Do you handle full projects or only separate works?

We handle both. OKTO works across extensions, refurbishments, roofing, landscaping, interiors, and bespoke construction. For larger projects, we can bring several parts of the work under one managed scope, so the client is not left coordinating five different trades alone.

How do you prepare a quote?

We start with the brief, the site, and the level of finish you want. Where suitable, we can prepare three specification options, so you can compare different levels of scope, materials, and finish before deciding. This makes the quote clearer and helps avoid the usual “cheap at first, expensive later” nonsense.

Can I see previous projects before choosing OKTO?

Yes. We can show relevant examples, including completed work, before and afters, and projects at different stages where available. Real work matters more than polished promises.

Do I need planning permission before contacting you?

No. You can contact us before everything is finalised. Some projects may fall under permitted development, while others need planning permission or building regulations approval. At the early stage, we help you understand what is likely to be needed before time and money are wasted in the wrong direction.

Is the work insured or protected?

Yes. Projects are supported by proper insurance, and where applicable, insurance-backed protection through a recognised guarantee provider. This gives clients more confidence that the work is being handled through a serious, accountable process, not just a handshake and good vibes.

How long will my project take?

It depends on the scope, approvals, materials, and site conditions. A small refurbishment may take weeks, while an extension or full renovation can take several months. After reviewing the brief, we outline the likely stages, dependencies, and realistic timing before the project starts.
