LSBUD explained: the free utility search before digging

If you're having work done that involves digging, you might hear an installer mention LSBUD. Here's what it is, what it does and what it doesn't.

What LSBUD is

LSBUD stands for LinesearchbeforeUdig. It's a free online service that checks a digging site against the records of more than 160 UK utility network owners.

Those networks include gas, electricity, water, high-pressure fuel and fibre optic cables, both underground and overhead.

How it works

1. Whoever is planning the dig marks the site on a map and gives details of the work.
2. LSBUD shows straight away which of its member companies have networks near the site.
3. Those companies then send plans of their pipes and cables, or confirm they're not affected.

Many responses arrive within minutes. Some companies take longer, up to around 10 days, which is why a good installer searches when you book rather than on the day.

What it doesn't cover

LSBUD is a great starting point, but it isn't the whole picture.

• Not every network owner is a member. The search lists any non-members in the area, and it's up to the person digging to contact them.
• It doesn't show private services. Your supply pipes and cables, and anything added on your property, won't appear. See what's under your driveway.
• Plans are a guide, not a guarantee. Records can be out of date or approximate.

That's why a search should always be followed by questions about private services and a scan of the ground before digging.

Can I use it myself?

Yes. Anyone can register and run a search for free. If you're planning your own digging project, it's worth doing.

How we use it

Every Stratfield job starts with an LSBUD search when you book. We review the plans, contact any non-members, chase anyone who hasn't replied, and keep the results on a written record for your job. Then we ask you about private services and scan on the day. See our full process.

Questions people ask

Does it cost anything? No. LSBUD is free to use.

Is an LSBUD search a legal requirement? There isn't a specific law requiring LSBUD, but anyone digging has a duty to avoid danger from buried services, and HSE guidance expects plans to be checked before work starts. Many insurers also require it.

What's an LSBUD reference? Each search gets an enquiry reference. Ask your installer for it if you'd like to see what was checked.
