Pool Contractors
Pool Contractors near you
Hiring someone to build, refit or look after a private pool in Britain is an exercise in choosing well rather than checking a register, because no register exists. There is no pool builder's licence, no pool technician's licence and no mandatory qualification for anyone who offers to service a domestic pool. That is not a gap peculiar to pools: most construction trades here are unlicensed, and the protections come from building control, from the electrical competent person schemes and from ordinary consumer law rather than from a badge.

The bigger surprise for anyone who has read pool advice written in Australia or the United States is the safety position. Those countries have statutory barrier laws with measured heights, self-closing gates and inspection regimes. Britain does not. HSE says plainly that there are no specific health and safety laws for swimming pools, and the detailed HSE guidance that does exist is aimed at pools used by the public, not at the one in your garden. A homeowner here is choosing a standard rather than meeting one.
So the practical job is to work out which trade you actually need, to decide in advance what safety measures your household will have, and to make the contract carry the things the law is not carrying for you: who notifies the electrical work, what standard the finished pool is built to, and what happens if the person who installed it stops answering the phone.
Four different trades all call themselves pool contractors
- Pool builders and installers, who do the excavation, shell, plant room and finish, usually subcontracting the groundworks and the electrics.
- Refurbishment specialists, who reline, retile, re-render or replace plant on an existing pool without touching the structure.
- Service engineers, who run the weekly or fortnightly water care, change filter media and diagnose pumps, heaters and controllers.
- Pool enclosure and cover firms, who work on the building, the roof or the mechanical cover rather than on the water.
- Behind all four sit two trades the pool firm does not normally employ: an electrician working to BS 7671, and a groundworker or structural engineer where ground conditions are difficult.
- Asking which of these the quoting company does in-house, and which it subcontracts, explains most of the difference between two prices.
Britain has no domestic pool fencing law, and that changes what you have to decide
This is the sentence that most needs saying on a British page, because the internet is full of pool safety advice written where the opposite is true. HSE's own guidance on swimming pool safety management opens by stating that there are no specific health and safety laws for swimming pools, and that operators instead comply with the general duties in the Health and Safety at Work etc Act 1974 by making a suitable and sufficient assessment of the health and safety risks to workers and users. There is no statutory barrier height for a domestic pool anywhere in England, Scotland, Wales or Northern Ireland, no self-closing gate specification, and no inspection that anyone will come and carry out.
The detailed guidance that does exist stops short of your garden. HSE's Health and safety in swimming pools, HSG179, is in its fourth edition, published in 2018 and reissued with minor amendments in February 2024, and it applies to pools used by the public for water-related activities as defined in British Standard BS EN 15288-2 as Type 1, 2 or 3. A private family pool is none of those. HSE also notes that guidance may reach other non-conventional settings such as holiday lets in residential complexes, which is a useful warning if you ever intend to let the house.
That leaves the decision with you, and it is worth making deliberately rather than by default. The Royal Life Saving Society UK's advice for residential pools is to keep children under the constant supervision of a capable adult, to stop children reaching the pool by installing secure fencing at least four feet high, and to have rescue aids such as a torpedo buoy, rope or reach pole within easy reach. Those are recommendations, not requirements, and a contractor who tells you a fence is legally mandatory in Britain is repeating something they read somewhere else.
What a domestic pool is actually built to, when no law sets the standard
Because statute is silent, the reference points are British Standards adopted from European ones, and they are voluntary. The domestic series is BS EN 16582, published in 2015: Part 1 sets the general requirements, Part 2 covers partially or fully inground pools with a minimum water depth exceeding 400mm, and Part 3 covers aboveground pools. A separate series, BS EN 16713, published in 2016, deals with the water systems, with Part 2 on circulation systems and Part 3 on water treatment. The public-pool series, BS EN 15288, is explicitly not applicable to domestic pools.
None of that is enforced by anyone, which is precisely why it belongs in your specification rather than in the small print. Asking a builder to state in writing that the pool, its circulation and its treatment system are designed to those standards is a reasonable request, and the answer tells you whether they know the standards exist. Where a firm says it works to its own specification instead, ask what that specification says about turnover rate, freeboard, hydraulics and the depth-to-diving relationship.
Two things are regulated whatever the pool. The electrical installation must comply with BS 7671, and in England and Wales the work sits under Part P of the Building Regulations with its own notification route. The connection to the water supply is governed by the Water Supply (Water Fittings) Regulations 1999, which set notice requirements for certain pool installations. Those are covered in the pool installation guide; what matters here is that both produce paperwork, and you should be told at quotation stage who will hand it to you.
The permissions a pool job touches, and who chases them
- Planning: an outdoor pool in a back garden is usually permitted development in England, with tighter limits on designated land and none at all within the curtilage of a listed building.
- Building control: the pool basin itself often sits outside it, while a pool hall, an enclosure or a structural alteration does not.
- Electrical: new circuits and work in the zones around the basin are notifiable in England, and a competent person scheme member can self-certify instead.
- Water: certain pool installations require notice to, and the consent of, the water undertaker before filling.
- Scotland uses a building warrant granted by the local authority verifier, and Northern Ireland has its own building regulations, so an English answer is not transferable.
- Settle in the contract which of these the contractor applies for, which you apply for, and what the programme assumes about response times.
Running a tender for pool work without a licence to check
- Ask each firm for two references on pools of the same construction, and visit one that is at least five years old rather than one finished last summer.
- Get the specification, not just the price: shell construction, circulation design, turnover, plant, finish and commissioning should all be named.
- Require public liability insurance details, and for a build, confirmation of who holds the Construction (Design and Management) duties.
- Ask which electrician will do the work, which competent person scheme they belong to, and when you will receive the certificate.
- Stage payments against completed and inspected work rather than against dates, and never pay for materials that are not on site.
- Put the safety measures you have chosen into the specification, because a fence, an alarm or a safety cover added afterwards costs more and fits worse.
- Agree in writing what happens in the first winter, which is when a badly detailed British pool shows its faults.
Warning signs in a pool quotation
- A claim that a fence is legally required, which suggests the quote was built from overseas material.
- A single lump sum with no breakdown between shell, plant, finish, electrics and commissioning.
- A large deposit before any site work, particularly one described as securing materials at the current price.
- No mention of who notifies the electrical work or which scheme certificate you will receive.
- No plant room in the drawing, or a plant room too small to get a filter vessel out of later.
- A programme with no allowance for British weather on an excavation, which is the item that most often slips.
- Reluctance to name the products and the finish, which makes any later warranty conversation almost impossible.
What drives a pool contractor's quote, and how LokalMatch fits in
Pool quotations separate on access, ground and specification long before they separate on the water. What moves the figure is whether a machine can reach the site or the spoil has to be barrowed out through a house, what the ground turns out to be once it is open and whether groundwater is present, how far the plant room sits from the basin, the construction method chosen, the finish, the heating and circulation specification, and how much builder's work the pool firm has to carry out around the pool rather than in it. Refurbishment and service work turn on different things again: the age and construction of the existing pool, whether the plant is still supported, and how much of the old installation has to be stripped before anything new can go in.
LokalMatch is the introduction and nothing more. Set out the pool, the site and what you want done, once, with your postcode, and contractors who cover your area will contact you with their own approach and their own numbers. There is no charge to homeowners; the pros pay for the enquiries that reach them. LokalMatch does not carry out pool work, does not set or influence prices, and does not vet, rank or recommend any firm that replies, so the checks on insurance, references, specification and electrical certification are yours to make.
Pool Contractors: frequently asked questions
Is a fence around a private swimming pool a legal requirement in the UK?
No. There is no statutory barrier standard for a domestic pool anywhere in the United Kingdom. HSE's guidance on swimming pool safety management states that there are no specific health and safety laws for swimming pools, with duties instead flowing from the general provisions of the Health and Safety at Work etc Act 1974 for those who operate pools as a business. The Royal Life Saving Society UK recommends secure fencing at least four feet high around a residential pool along with constant adult supervision, but that is safety advice rather than law. Advice you find quoting a specific fence height as a legal requirement is almost always written for Australia or a US state.
Does HSE guidance on swimming pools apply to my garden pool?
Generally not, because of how HSG179 defines its own audience: it is aimed at pools open to the public, sorted into Types 1, 2 and 3 by a British Standard, and a family pool is in none of those categories. Where it starts to matter is letting. HSE flags holiday lets in residential complexes as one of the less conventional settings its material can reach, so a pool that comes with a booking is worth treating as a business system rather than a household one.
Do pool contractors have to be licensed or registered in Britain?
No. There is no licence or register for pool builders, pool refurbishment firms or pool service engineers in the United Kingdom, and no qualification anyone must hold to trade as one. The regulated pieces are the parts other trades do: electrical work must comply with BS 7671 and, in England and Wales, with Part P of the Building Regulations, which is why the electrician's competent person scheme membership is a real credential rather than a logo. Everything else rests on references, insurance and a specification you can hold someone to.
Which British Standard should a domestic pool be built to?
The relevant voluntary series is BS EN 16582, published in 2015, with Part 1 covering general requirements, Part 2 partially or fully inground pools with a minimum water depth exceeding 400mm, and Part 3 aboveground pools. The water systems are dealt with in BS EN 16713, published in 2016, including circulation systems in Part 2 and water treatment in Part 3. BS EN 15288, the public pool series, is not applicable to domestic pools. None of these is legally binding on a homeowner, so naming them in the specification is what gives them force.
Should the pool builder or I apply for planning permission?
Decide it explicitly and write it down, because the programme depends on it. An outdoor pool in a rear garden is often permitted development in England, but designated land, listed buildings and anything enclosed in a building change the answer, and Scotland and Northern Ireland run separate systems. Contractors will frequently offer to handle the application, which is fine provided the contract says what happens to your deposit and their programme if the answer is no.
What should a pool contract say about the electrics?
Three things: which electrician is doing the work, which competent person scheme they belong to, and when you receive the certificate. Pool electrical work is not ordinary garden wiring, because the area around a basin is a special location with its own requirements in BS 7671, and an installation signed off properly is also the document a future buyer's solicitor will ask about. If nobody in the quotation will put a name to the electrical work, that is the item to resolve before anything else.

What affects the cost of pool
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Type and size of pool or hot tub
- Excavation and site access
- Pumps, filters, heaters and covers
- Decking, fencing and landscaping around it
- Electrical and gas connections
- Condition of existing equipment for repairs
How to compare pool contractors before you hire
- Choose a company that works on your type of pool or hot tub, whether it's in-ground, above-ground or a spa.
- For a new pool, ask who handles the permit, the fencing requirements and the electrical and gas connections.
- Make sure electrical and gas work for heaters, pumps and hot tubs is done by licensed trades.
- Get a written quote that covers excavation, backfill, equipment, decking and site restoration.
- For openings, closings and maintenance, ask exactly what each visit includes.
Questions to ask pool contractors before you hire
- Who will get the permit, and what fencing or gate rules will I need to meet?
- Who will do the electrical and gas hookups, and are they licensed?
- What equipment do you recommend, and why?
- What does the warranty cover for the pool shell or liner, the equipment and your installation?
- How will you get equipment into my yard, and how will you restore the lawn afterwards?
- What is included in an opening, closing or maintenance visit?
When to call a pro for pool
- Water level dropping faster than usual, which may mean a leak
- A pump, heater or hot tub that trips the breaker: keep people out of the water and call a qualified technician.
- Cloudy or green water that doesn't clear with regular care
Pool permits and local rules
Some pool work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
