What's covered

Tap what you need

Each one takes you straight to the right question — about two minutes, mostly multiple choice.

We know the worries

The worries that come with building work

“Where do we even start — plans, permission, builder?”

Start with the conversation. The specialist walks you through what your project needs — drawings, permissions, building regs — in the right order, before anything is committed.

“Can we live here while it happens?”

Usually, with planning. How the site is separated, kept safe and kept clean is discussed up front, not improvised.

“I’ve heard the horror stories”

So have we — they’re why the vetting exists. Finished projects seen, quotes honoured, and customers who’d use the same builder again.

Your specialist

The specialist we'll match you with

Every company representing a trade on SEHI passes the same vetting: finished work seen and assessed, written quotes that are honoured, proper insurance, and customers treated well from first visit to aftercare. Tell us what you need and we'll match you with a vetted specialist covering your area.

  • Certification: Every project is signed off through building control — that's the law on structural work — and we look for vetted company marks such as FMB membership
  • Insurance cover: Public liability insurance — required before any specialist joins the network
  • Workmanship guarantee: A written guarantee on the build — terms, including any insurance-backed structural warranty, confirmed in your written quote
Specialists are named to you when we make the match — we describe them generically here by design.

Questions

Fair questions, straight answers

Is the quote really free, with no obligation?

Yes. The first visit and the written quote cost nothing, and there’s no pressure to go ahead.

Do I need planning permission?

It depends on the project — some fall under permitted development, some don’t. The specialist will tell you where yours stands and what the next step is.

Do I need an architect first?

Not necessarily. Come with finished drawings or just an idea — the specialist tells you what your project actually needs.

Will my details be passed to other companies?

No. One vetted company only — never a list of bidders.

What happens after I send the form?

We match your enquiry to a vetted specialist covering your area, and they email you to arrange a first visit.
