THE 60-SECOND VERSION

Hiring a pond builder in five steps

  1. Decide the pond's jobWildlife, fish or ornamental — depth, filtration and shelves follow from it.
  2. Ask where the soil goesA pond produces tonnes of spoil. Reused in the garden, or taken by a registered waste carrier.
  3. Plan the powerPump, filter and UV need a safe outdoor supply wired by someone who can certify it.
  4. Check the mains top-up ruleOver 10,000 litres and auto-filled from the mains: the water company must consent first (England and Wales).
  5. Get the liner and underlay namedMaterial, thickness and guarantee — the liner is what fails.

BEFORE YOU BOOK

Check before you book

No register applies

The law sets no licence and keeps no register for pond builders, in England, Wales, Scotland and Northern Ireland alike. The checks are the build specification, ponds they have built, and the rules on water, power and waste.

Ask to see a pond they built two or more years ago.

Water company notice for large ponds (England and Wales)

Regulation 5 of the Water Supply (Water Fittings) Regulations 1999 requires notice to the water undertaker, and its consent, before building a pond or pool of more than 10,000 litres that is designed to be topped up automatically with mains water.

If your pond is that size with an automatic top-up, ask the pond builder who gives notice, and keep the consent. legislation.gov.uk →

Electrics for the pump

Power for a pond pump, filter and lights is electrical work, not part of the pond builder's trade unless they are also an electrician. Electrical work in a home in England and Wales must meet the Building Regulations; Wales treats outdoor work as notifiable. A Registered Competent Person Electrical electrician certifies it.

Ask who wires the supply and which certificate you will receive. electricalcompetentperson.co.uk →

Waste carrier registration

A pond builder who drives away the excavated soil and stone is transporting waste as a business, which needs registration: with the Environment Agency in England, Natural Resources Wales, SEPA in Scotland or the NIEA in Northern Ireland.

Ask for the carrier number and search it on the public register before anything leaves. environment.data.gov.uk →

VAT

Building a pond is standard-rated at 20%. A pond builder turning over more than £90,000 a year must register, charge it and show the 20% separately on the written quote.

Ask the pond builder for the VAT number and check the 20% is a separate line below the liner and pump. gov.uk →

“How deep will the pond be, and why?”

A good answer: A depth that suits its purpose — deeper zones for fish to overwinter, shallow shelves for wildlife and plants.

“Which pond liner and underlay will you use?”

A good answer: Material and thickness named, with the manufacturer's guarantee.

“What filtration and pump does the pond need?”

A good answer: Sized to the volume and the fish load, with the flow rate stated.

“Who wires the pond pump, and what certificate do I get?”

A good answer: An electrician who can certify the work — an Electrical Installation Certificate or Minor Works Certificate.

“Where will the pond spoil go?”

A good answer: Reused for a rockery or levels, or taken by a registered waste carrier.

“Does my pond need the water company's consent?”

A good answer: If it is over 10,000 litres with an automatic mains top-up in England or Wales, yes, and they say so.

“How will you make the pond safe for children?”

A good answer: Options named: a mesh or grid, a raised edge, or a shallow design.

Getting the quote right

  • Pond size, depth and volume
  • Liner and underlay, named with thickness
  • Pump, filter and UV unit, named, and who wires them
  • Spoil: reused on site or removed, with the carrier number
  • Edging, planting and any safety grid
  • Who actually attends to dig, line and wire the pond, and whether they are employed or subcontracted
  • The VAT number, with VAT at 20% shown apart from liner, pump and labour

Walk away if

  • An extension lead from the kitchen as the pump supply
  • No idea what happens to the spoil
  • No underlay under the liner
  • A deposit for the whole job before digging starts

What a pond builder costs: £800–£7,500 per project

Ponds are priced by the project; size and depth, the liner, the filtration and the amount of spoil to remove set the price. Pond Installation price guide →

AFTER

When the job is done

Keep the electrical certificateWith the liner and pump guarantees and the invoice.
Watch the water level for a weekA steady fall beyond evaporation means a leak at the liner or edge.
Learn the filterHow to clean it, and when the UV lamp needs changing.
Rate the workBooked through Locufy, the job can be reviewed; if the pond builder needs to come back, the make-it-right step gives them the chance first.

STEP 1Start with the pond builderSet out in writing what went wrong with the pond. Section 49 of the Consumer Rights Act 2015 is the duty of reasonable care and skill; section 55 lets you ask for the service to be repeated.
STEP 2Let Locufy follow it upBelow four stars, you choose whether the pond builder sees the problem before your review does; we follow it through, then the review goes live.
STEP 3No regulator: Trading StandardsFor advice, or to have Trading Standards told, ring Citizens Advice on 0808 223 1133 in England and Wales, Advice Direct Scotland on 0808 800 9060, or Consumerline on 0300 123 6262 in Northern Ireland.
STEP 4Small claimsKeep the quote, the photos and every message with the pond builder: claims up to £10,000 in England and Wales, £5,000 in Scotland and £5,000 in Northern Ireland are heard on the small-claims routes.

Hiring a pond builder: questions people ask

Neither a licence nor a register is required of pond builders, whether in England, Wales, Scotland or Northern Ireland. The pump supply is electrical work with its own rules.

Usually not for planning in England, where a garden pool counts as permitted development within limits. A pond over 10,000 litres with automatic mains top-up needs the water company's consent in England and Wales.

Expect £800 to £7,500 a project, most often near £2,400. Our pond installation price guide covers what changes it, and the search above lists pond builders where you live.

In England and Wales an electrician on the Registered Competent Person Electrical register can certify it; in Wales outdoor electrical work is notifiable.

A small wildlife pond is a day or two; a large fish pond with filtration takes a week or more.

Yes, reused for a rockery or levels; otherwise it must leave with a registered waste carrier.
