A little clarity before you begin
From the first idea to looking after the finished pool, explore the practical things that matter when you are deciding whether natural swimming is right for your garden.
01 / The starting point
Understand the different approaches and what living with natural water really means.
It is a pool designed for swimming that uses biological filtration rather than routine chlorine dosing to manage the water. Unlike an ordinary garden pond, the swimming area, water treatment and circulation are planned together for bathing. The finished design can look like a landscaped pond or a more architectural pool, depending on your garden and the system chosen.
Explore how natural pools work ↗Our swimming ponds have a softer, more naturalistic appearance with generous planting. Our natural pools combine a defined swimming area with a visible planted regeneration zone. Living pools use concealed biological filtration for a more conventional pool appearance without a large planted filter zone. The best choice comes down to the look you enjoy, the space available and the care routine you prefer.
Compare the pool styles ↗No. Planted swimming ponds and natural pools use a regeneration area as part of their treatment system, while a living pool can use purpose designed biological filters without a large aquatic planting zone. Choosing less planting does not remove the need for filtration, servicing space or water care. It changes how those functions are provided and how the garden looks.
Learn about living pools ↗No, that is not the intention of a purpose designed swimming pond. The swim zone has a defined, lined or finished base, with aquatic planting kept in a separate regeneration area. You swim alongside the planting rather than through it. Leaves and some sediment can still settle on the bottom, which is why occasional cleaning remains part of ownership.
Yes. Straight edges, a rectangular swimming area, carefully selected paving and restrained planting can create a very clean, architectural result. A living pool is particularly suited to a conventional pool appearance, while a natural pool can keep structured lines with planting alongside. Natural water describes the approach to treatment, not a requirement for a rustic shape or an untidy garden.
See our natural pool approach ↗You are choosing a managed living system, not a maintenance free feature. Planted designs need space and seasonal gardening, outdoor water attracts some wildlife, and algae or sediment may need attention. Specialist design and construction also represent a significant investment. A natural pool is best suited to someone who enjoys this relationship with the garden and is comfortable with a clear, regular care routine.
02 / The investment
Guide prices, what is included and the ongoing commitment beyond the build.
Our guide prices start at £45,000 excluding VAT for a swimming pond and £80,000 excluding VAT for either a natural pool or a living pool. VAT is additional and will be shown in your proposal, so these are not the final amounts payable. Size, access, ground conditions and finishes affect the total. Our £12,000 excluding VAT wildlife pond starting price is for a habitat pond, not a swimming facility.
Read the full price guide ↗Look for a clear scope covering design, excavation, the shell or liner, the specified filtration and circulation, and the regeneration area and planting where applicable. Also check spoil removal, electrical work, access arrangements, commissioning and handover. Surrounding terraces, paths, decking and garden reinstatement should be explicitly listed as included or separate, rather than assumed to be part of the headline price.
Allow for the electricity used by the specified pumps and equipment, routine cleaning, seasonal planting care and any professional maintenance or replacement parts. The useful figure is one calculated from your system's power use, operating schedule and electricity tariff. We would not apply one annual running cost to every pool, because a compact living pool and a large planted swimming pond have different requirements.
Not automatically. A fair comparison needs the same swimming size, construction standard, finishes and surrounding landscaping. A planted system may require more excavation and land, while a living pool uses more concentrated filtration equipment. You are not budgeting for routine chlorine dosing, but electricity, cleaning and servicing still matter. Compare the complete installation and ownership costs rather than assuming either option will always be cheaper.
A simpler shape, straightforward access and restrained finishes can help keep the scope under control. It may be possible to phase surrounding landscaping, decking or lighting, provided future connections and access are considered from the start. The pool structure, water treatment and essential safety arrangements need to form a complete working installation. Reducing filtration simply to meet a headline budget is not a sensible saving.
Two gardens with the same proposed swimming area can involve very different work. Restricted access, ground levels, soil conditions, groundwater, buried services and the route for removing excavated material can all change the build. A site visit helps establish those details and identify where further investigation is needed. The result is a proposal based on your property rather than a square metre rate that leaves important costs unexplained.
03 / Your space
Space, depth, trees and ground conditions, considered around your own property.
Start with the area you want to swim in, then allow for the chosen treatment system, safe edges, entry points and maintenance access. A planted swimming pond needs a regeneration area in addition to the swimming space. There is no single percentage that applies to every system, so comparing only the water's outline can be misleading. The design should show the complete footprint within your garden.
A compact design may be possible, particularly with a living pool that does not require a large planted regeneration zone. The practical test is whether the garden can accommodate a useful swimming area, the required filtration and safe access without overwhelming the rest of the space. Tell us whether you want proper lengths, gentle exercise or somewhere to dip, because those uses lead to different layouts.
Depth should follow the intended use, the swimmers and the structural design, rather than a universal rule. Discuss comfortable standing areas, swimming depth, steps and any changes in level during the design stage. A shallow shelf is not a substitute for supervising children. Do not assume a pool is suitable for jumping or diving unless it has been specifically designed and assessed for that activity.
Trees and shade need to be considered, but they do not produce a simple yes or no answer. Falling leaves increase cleaning and nutrient inputs, roots can affect construction, and aquatic planting needs conditions suited to the species selected. We look at the position through the seasons and the relationship with existing trees. Avoid choosing the pool location without considering future growth and access for maintenance.
They can change the engineering and cost, but do not automatically rule a project out. Ground investigation may be needed to understand stability, drainage and groundwater before the structure is specified. A slope can require retaining work and a considered access route. The important point is to identify these conditions before agreeing the design, rather than treating them as surprises once excavation has started.
The amount of equipment and the space it needs depend on the system. Pumps and any air equipment need a suitable location, a professionally installed electrical supply and access for inspection and servicing. Noise should be considered alongside bedrooms, seating areas and neighbouring properties. Concealed equipment can make the garden look calmer, but it still needs to remain accessible rather than being permanently built over.
04 / Making it happen
Permissions, access, timescales and the journey from excavation to the first swim.
Some domestic garden pools in England can fall within permitted development, but the rules depend on the house, the location and the full proposal. Restrictions, previous development and associated structures can affect the answer. Calling a project a pond does not automatically remove the need for consent. Check with your local planning authority before starting work and establish whether written confirmation or an application is appropriate.
Check Planning Portal guidance ↗Additional restrictions may apply to listed properties and designated areas, including conservation areas, National Landscapes and the Broads. This does not mean every location has identical rules. The position and extent of the works matter. Speak to the relevant planning authority early, and establish whether planning permission, listed building consent or other approvals are needed. Include decking, outbuildings and substantial landscaping in that discussion.
Read our planning guide ↗Our current guide allows two to four weeks for design and eight to sixteen weeks for construction. These are working estimates, not a guaranteed completion date. Permissions, investigations, scheduling, access, weather and the complexity of the finish can change the programme. Commissioning and handover also need to be allowed for, so discuss your preferred completion period early rather than booking an event around the shortest estimate.
Follow the build process ↗Restricted access does not always prevent a build, but it can change the machinery, handling methods, duration and cost. We need to understand gate widths, tight corners, overhead obstacles, gradients and the route for bringing materials in and taking spoil out. Send photographs of the whole access route, not just the proposed pool location, so practical constraints can be discussed before a site visit.
Expect a genuine construction project, with excavation, deliveries, machinery and temporary access routes. Before work starts, agree which areas will be protected, where materials will be stored and what reinstatement is included. Excavated material may be suitable for an agreed landscaping plan, but not all spoil can or should stay on site. Removal, handling and any relevant disposal requirements need to be included in the scope.
Wait until the installation has been commissioned, the required water checks are satisfactory and you have been told it is ready for use. A pool looking full and clear is not enough on its own. Planting and the wider biological system continue to establish after construction, which is different from being ready for an initial swim. Your handover should explain any early use limits and the first season's care.
05 / Beneath the surface
How the water is managed, what can change and when to ask for advice.
The system combines circulation, biological filtration and control of the nutrients entering the water. Depending on the design, treatment takes place in a planted regeneration area, dedicated filter media or a combination of both. Surface skimming and removing debris also help. It is the complete system that does the work, not simply putting a few plants around the edge of an otherwise conventional pool.
Read about biological filtration ↗A natural pool needs a suitable design, commissioning checks and an ongoing water management routine. Clear water alone does not prove that it is safe to swim in. Agree what needs testing, how often and what should trigger an additional check for your installation and intended use. Changes in water quality, unusual contamination or a treatment fault should be assessed before normal swimming resumes.
Algae can appear, especially while a pool is establishing or when nutrient inputs and operating conditions change. Persistent growth needs investigation of the particular system, rather than an automatic dose of pond chemicals. Remove leaves and prevent fertiliser or dirty surface water washing into the pool. Unusual scum or a suspected harmful algal bloom is different from routine cleaning. Keep people and pets out until it has been assessed.
Read independent healthy swimming guidance ↗A biological film can develop on surfaces in natural water, so steps, ladders and frequently used edges need regular attention. Suitable finishes, well considered entry points and the correct cleaning routine help manage this. Ask which brushes and cleaning equipment are compatible with your liner or finish. Do not assume that a clear looking pool has slip free surfaces, or use aggressive cleaning products without checking first.
Rainwater, wherever possible. UK mains water often has phosphate added, and phosphate is the nutrient that feeds algae, so we design roof water collection and storage into the project from the start where the site allows. Borehole water can also work once it has been tested, because its mineral and nutrient levels vary from site to site. If mains water has to make up part of the first fill, we plan for that in the design rather than leaving it to the end.
Follow the operating instructions for your particular system and contact your installer when circulation does not restart as expected. There is no universal number of hours for which every pool can safely operate without treatment. Avoid swimming if the treatment system is compromised until you have appropriate advice. Do not open electrical equipment or repeatedly reset a tripping circuit; electrical faults need a qualified professional.
Explore pool servicing ↗06 / Everyday ownership
The regular jobs, seasonal care and support that keep the pool working as intended.
Our general guide is around an hour a week during the growing season, but the actual routine depends on pool size, nearby trees, planting and equipment. Typical jobs include removing leaves, emptying the skimmer and checking water level and circulation. Planted systems also need seasonal cutting back and thinning. It is manageable regular care, not a promise that every installation will need exactly the same amount of work.
Read the maintenance guide ↗A compatible cleaner can help remove sediment from the swimming area, but it needs to suit the pool's shape, slopes, depth and surface finish. Not every robot is suitable for every natural pool. Keep equipment out of planted filter areas unless the maintenance instructions specifically allow it, and check the recommended cleaning method before buying. The aim is to clean the swim zone without disturbing the treatment system.
A natural pool is normally left full rather than emptied each winter. The seasonal routine for pumps, pipework and other equipment depends on the installation, so follow your handover instructions rather than applying a generic shutdown checklist. Leaves still need attention and planting may require selective cutting back. Never drain the pool without advice, because the structure, liner and groundwater conditions need to be considered.
Some topping up can be needed because of evaporation, splashing and the particular maintenance routine. Routine complete water replacement is not the normal approach to managing a natural pool. Monitor the water level and top up with stored rainwater where you can, as mains water often carries added phosphate that feeds algae. An unexplained or persistent loss needs investigating rather than continually adding more water, particularly if it changes how the skimmer or circulation system operates.
Yes. We offer aftercare covering the planting and pool care routine, alongside servicing for the equipment specified in your installation. Gardening and mechanical servicing are related but different jobs, so agree exactly what each visit includes. We can discuss the right arrangement during handover and explain which checks remain the owner's responsibility between visits. Existing pools built by other installers can be considered following an assessment.
Explore maintenance and aftercare ↗Arrange for someone to carry out the essential checks in your care plan, particularly the water level, skimmer and operation of the equipment. Explain who to contact if something changes and how access to the water will be controlled while you are away. Do not switch the filtration off simply because nobody is swimming. A longer absence is worth discussing in advance so suitable care can be arranged.
07 / Sharing the garden
Practical answers about pond life, pets and responsible use of the water.
A planted swimming pond can attract local wildlife, and seeing pond life around the regeneration area is part of its character. The swimming space is designed separately, but wildlife cannot be guaranteed to remain on one side of an outdoor pool. A living pool offers a less planted appearance, not an insect proof environment. Discuss your expectations honestly when choosing which type of natural swimming suits you.
No outdoor garden can be guaranteed to be free of mosquitoes. Pool circulation and the condition of the planting need to be considered alongside standing water elsewhere on the property, such as neglected containers and blocked drainage. Tell us about any existing mosquito problem during the design conversation. We would not promise that building a natural pool will either eliminate insects or leave the wider garden completely unchanged.
Fish are generally not part of a natural swimming pool design because their waste and food add nutrients that the water treatment system then has to manage. A pool designed for bathing should not be treated as a stocked ornamental pond. Where keeping fish is important to you, discuss a separate pond rather than adding them after the swimming pool has been commissioned.
Tell us about dogs at the design stage rather than assuming every installation is suitable. Their use affects entry and exit arrangements, cleaning and the load placed on the water treatment system, while claws can be a concern for some finishes. Agree what the specific pool can accommodate and how it will be managed. Keep dogs out whenever water quality is uncertain or an algal bloom is suspected.
A natural pool has the same fundamental drowning risk as any other body of water. Children need active adult supervision, and preventing unsupervised access should be considered from the first design conversation. Shallow planting shelves, clear water and swimming ability do not remove that responsibility. Discuss steps, edges, handrails and access controls around your household, including visiting children, rather than relying on the pool's natural appearance.
Read RoSPA garden safety guidance ↗Access controls and a suitable safety cover can be explored as part of the design, but the right arrangement depends on the pool's shape, edges and surrounding garden. Not every cover works with a planted layout. A leaf net or ordinary pool cover is not automatically a safety device. Any protective system needs to be specified, installed and used correctly, and it does not replace supervising children around water.
08 / Your next step
Existing pools and ponds, seeing the design and starting a conversation with us.
An existing pool may be suitable for conversion, but its structure, finish, pipework and available treatment space need assessing first. The proposal might use an added regeneration area or a dedicated biological filtration system. Conversion is not simply a matter of stopping chlorine dosing. Establish what can be retained, what must change and how the finished system will be commissioned before deciding whether conversion is the right investment.
Explore pool conversions ↗Possibly, but an ornamental or wildlife pond should not be assumed suitable for swimming. Its water source, structure, depth, accumulated sediment and treatment arrangements all need considering, alongside safe access and the surrounding habitat. The work required can be substantial, so retaining the exact outline is not always the best solution. We would assess the existing pond before recommending adaptation, rebuilding or a separate swimming area.
Yes. Our design process includes plans and visualisations to help you understand the layout in the context of your own garden. You can review the swimming area, planting, materials and relationship with the house before deciding on construction. Visualisations communicate the design intention, while the agreed drawings and specification establish what is actually included. Any changes should be reflected in those documents before the build is authorised.
See how we present your design ↗We design and build natural swimming pools across Suffolk, Norfolk, Cambridgeshire and Essex. Share your postcode at the start of the conversation so we can confirm the practical arrangements for your site, including visits and aftercare. For a property outside these areas, contact us before making plans rather than assuming the same service arrangements will apply everywhere.
Discuss your location ↗Our initial design consultation is a free, no obligation opportunity to discuss your garden, how you hope to use the pool and a realistic starting budget. Photographs, approximate dimensions and pictures of the access route are helpful. Bring examples of styles you like and explain any important constraints. We can then discuss the next steps, including a site visit and any investigations needed before a detailed proposal.
Book a design consultation ↗Ask for the project warranties in writing, with a clear distinction between installation work, the liner or structure and manufacturers' equipment cover. The periods, exclusions and maintenance requirements should be set out in your proposal rather than assumed. Handover should explain normal operation, the care routine, water checks and who to contact about a problem. Keep those instructions and service records with your agreed specification.
