A patio is a paved outdoor area next to the house or in the garden, laid in porcelain, natural stone or concrete slabs on a compacted sub-base and mortar bed, with falls that direct rainwater away from the house.
Planning a new patio for a home in Hatfield means making a handful of decisions about materials, layout, finish and timing. We help you work through them at a free survey, then confirm in writing what it will cost for the options you pick. Most projects of this type need 3–7 days on site, and we cover every AL9 and AL10 address as well as the rest of Hertfordshire.

What should you budget for a new patio in Hatfield?
To help you plan, we show what a new patio typically costs in Hatfield instead of holding figures back for a sales call. The range is £2,600–£5,800 with VAT, using rates in the East of England that are about 5% above the national guide. A free survey then fixes your actual price.
| Type of job | What it usually involves | Guide in Hatfield |
|---|---|---|
| Small patio or path | Around 10m² of concrete slabs or a garden path. | £1,050–£2,600 |
| Typical 20m² patio | Sandstone or porcelain on a full sub-base with jointing and edging. | £2,600–£5,800 |
| Large or multi-level patio | Bigger areas, steps, retaining walls or premium stone. | £5,800–£12,500 |
The main things that change the figure:
- Patio area and the amount of excavation
- Slab material, size and laying pattern
- Ground levels, slopes, steps and retaining walls
- Access for materials and removing spoil
Scope of the work
- Survey of levels, damp-proof course, drainage and access
- Compacted MOT Type 1 sub-base
- Slabs laid on a full mortar bed with falls away from the house
- Jointing with mortar or a brush-in compound
- Edging and neat cuts around drains and walls
- Site cleared, waste removed and paving cleaned
Local housing and a new patio
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
In Hatfield, as elsewhere in Hertfordshire, we take the building's age and construction into account before recommending anything, because both can change what is involved in a new patio.
Planning and building rules in Hatfield
Hatfield is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
A ground-level patio in a back garden does not usually need planning permission in England. Raised decks or platforms more than 30 cm high do.
Building Regulations do not normally apply to patios, but levels must stay below the damp-proof course and drain away from the house.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
A visit to your home
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new patio.
Your fixed price
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Dates and permissions
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Build and hand over
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Questions about a new patio in Hatfield
What happens if my garden slopes?
A sloping garden can still have a level patio by cutting into the slope, building up with retaining walls, or creating terraces with steps between them. Retaining walls must be built to hold back the soil and allow drainage behind them. This adds cost but creates usable, level space. We look at the slope during the survey and suggest the most practical design.
Is porcelain or sandstone better for a patio?
Porcelain is dense, stain-resistant and stays looking clean with little care, making it a good choice if you want a modern, low-maintenance patio. Indian sandstone has natural colour variation and a softer, traditional look, and costs a little less, but it can stain and weather over time and benefits from sealing. Both make durable patios when properly laid. We bring samples to the survey.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new patio, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How long does it take to lay a patio?
Laying a typical 20m² patio takes around three to five days, from excavation and sub-base to laying, jointing and cleaning. Larger or multi-level patios with steps and walls take longer. The mortar bed needs time to set, so light foot traffic is usually fine after a day or two and furniture can go on after about a week. We confirm timings with your quote.
