South Way’s 120-home development gives Hatfield buyers another scheme to consider and existing homeowners a reason to review their competition this November. The important question is how the proposed homes compare with existing properties in AL10, rather than whether planning approval alone will increase or reduce local house prices.
Welwyn Hatfield Borough Council granted reserved matters approval to BDW North Thames on 2 October 2026, under reference 6/2025/2336/RM. This covers appearance, landscaping, layout and scale, following outline permission granted on 30 September 2025 for 120 homes and a two-form-entry primary school. The housing approval is an important milestone, although the school has a separate delivery process.
At Country Properties, we help buyers and sellers look beyond planning headlines to make informed decisions about property values, local competition and moving plans.
What has been approved on South Way?
The latest approval concerns residential development on land south of South Way, between Hatfield and Welham Green. The scheme will introduce additional housing options, with several features worth considering.
- Affordable housing: The council’s October officer report identifies 30 affordable homes, representing 25% of the development, including social rent, affordable rent and shared ownership.
- Energy performance: Buyers should review the specifications for individual properties, including heating systems, insulation and expected Energy Performance Certificate (EPC) ratings.
- Open space: The approved proposals include landscaping and open space. Buyers should check the plans to understand access, management arrangements and when facilities are expected to become available.
- Primary school: A two-form-entry primary school forms part of the outline permission. However, its detailed design and delivery are separate from the residential approval, meaning an opening date cannot yet be assumed.
For buyers, these details should be considered alongside property prices, layouts and availability. For existing homeowners, the development provides another reason to understand how their property compares with potential new-build alternatives.
Why this site received approval and what it tells us about the local planning picture
South Way was allocated as site HS11 in the adopted Local Plan, and outline permission had already established the principle of residential development. The October 2026 decision addresses the detailed residential proposals that followed.
For homeowners, this planning history provides useful context about future housing competition. However, approval does not guarantee property price growth or establish when every new home will become available.
The effect on individual properties will depend on their location, condition, asking price and the alternatives available to buyers at the time.
A professional property valuation can help homeowners understand these factors by comparing their property with recent local sales and competing listings.
What AL10 property prices look like right now
Understanding the local property market is important before considering how the South Way development might influence buyer decisions.
According to the Office for National Statistics (ONS), housing release updated on 21 October 2026, the provisional average house price in Welwyn Hatfield was £446,000 in August 2026, representing an annual increase of 0.7%.
However, this figure covers the wider borough, including different settlements and property types. It should not be treated as the average value of an individual home in Hatfield or the AL10 postcode.
Property values vary depending on location, size, condition and accommodation. A flat near the town centre, a terraced home in South Hatfield and a detached family property may appeal to different buyers and achieve different prices.
For sellers, recent comparable transactions provide a more reliable starting point than borough-wide averages alone. Reviewing current listings can also help establish how much competition a property might face when it enters the market.
Why Hatfield prices sit below the district average
Property prices across Welwyn Hatfield reflect a mixture of homes in different locations and price ranges. A borough-wide average and a town-level median use different calculations, so comparing them directly does not necessarily establish whether Hatfield offers better value.
Buyers should consider the type of property they can afford, its condition and the costs associated with ownership. Sellers should focus on completed sales of similar properties and the homes currently competing for buyer attention.
What the South Way development means for sellers in AL10
For homeowners in South Hatfield, the approval of 120 new homes raises an important question: could additional new-build properties affect demand for existing homes?
New developments can provide buyers with additional choice, but established properties may offer different advantages. Mature gardens, existing neighbourhoods and the opportunity to inspect completed accommodation can appeal to buyers who prefer an established home.
New-build properties may offer modern specifications, different layouts or developer incentives. The right comparison depends on the individual properties available and the buyer’s priorities.
Importantly, planning approval does not establish when all 120 homes will be released or occupied. Homeowners should therefore avoid making selling decisions based on an assumed construction or marketing timetable.
Instead, sellers can benefit from reviewing their property’s current market position, understanding competing listings and preparing a realistic pricing strategy.
Country Properties can help homeowners assess their property’s value, identify suitable comparable sales and plan their next move with greater confidence.
What the South Way development means for buyers in AL10
For buyers considering Hatfield, the South Way scheme could eventually provide additional housing options alongside existing properties.
However, comparing new and established homes involves more than reviewing asking prices. Buyers should consider room sizes, outdoor space, parking, energy efficiency, maintenance requirements and likely moving dates.
Planned facilities should also be distinguished from those already available. Buyers should check which amenities, transport connections and local services they can use immediately rather than assuming everything proposed will be delivered at the same time.
First-time buyers and the affordable housing quota
The development’s affordable housing provision includes different tenures, meaning not every property will be available through the same purchasing arrangements.
Shared ownership generally involves purchasing a share of a property while paying rent on the remaining share. Affordable rented homes have separate eligibility and allocation requirements.
First-time buyers should check the relevant housing provider, eligibility criteria, availability and ongoing costs before including a particular property in their plans.
Family buyers and the planned primary school
The proposed two-form-entry primary school could become an important local facility for families considering the development.
However, the residential approval does not confirm when the school will open or whether places will be available for particular households.
Families should review existing school admissions arrangements, available places and practical travel routes when comparing properties.
Energy efficiency and running costs
Energy performance is another consideration when comparing new-build homes with established properties.
Buyers should examine heating systems, insulation, ventilation and EPC information rather than assuming that a particular property type automatically guarantees lower energy bills.
For older properties, it is worth considering improvements already completed and any further work required. Household energy usage, tariffs and maintenance costs will also influence overall affordability.
South Hatfield in context: the wider AL10 community
South Hatfield offers access to the A1(M), while Hatfield railway station provides connections towards London. Buyers should check journey times from individual properties, including the route to the station and the services available during their usual commuting hours.
The Galleria on Comet Way and the University of Hertfordshire’s College Lane and de Havilland campuses are established features of the wider area.
For families, everyday considerations such as school journeys, shopping facilities, outdoor spaces and transport connections can be just as important as the property itself.
Visiting an area at different times of day can help buyers understand traffic, parking, lighting and the practicalities of living in a particular location.
Landlords: rental property registration is coming. Are you ready?
The new government rental property database brings another responsibility for landlords, and preparing early will help make the process smoother.
For rental properties in the East of England, including Hertfordshire, the announced registration period runs from 15 January to 14 April 2027, subject to confirmation against the latest official government guidance.
Landlords will need to start each registration and pay the applicable annual fee. An agent can help by submitting tenancy information, uploading compliance certificates and keeping those details updated on their behalf, where permitted under the scheme. However, landlords remain legally responsible for ensuring their registration is complete and accurate.
Across the Country Properties branch network, our local lettings teams can help landlords understand the upcoming requirements and prepare their property records ahead of registration.
Whether you own one rental property or manage a larger portfolio, preparing your documentation early can help you stay organised and ready for the changes.
