New Build Home Costs & Charges Planner

The New Build Home Costs & Charges Planner helps UK buyers estimate expenses that may sit outside a new build property's advertised price. Enter the expected upfront extras, developer incentives and annual charges to understand how they could affect your budget after reservation and completion.

What the Planner Includes

The planner includes reservation fees, flooring and developer upgrades, kitchen appliances, landscaping, parking or garage charges, snagging inspections and additional legal or mortgage fees. It also deducts any developer incentives entered and avoids adding upgrades that are already included in the property price.

Ongoing New Build Charges

Add expected annual service charges, estate management fees, communal-heating standing charges and parking or amenity fees. You can apply an estimated annual increase to explore how these recurring new build charges may change over your selected ownership period.

What Your Results Show

Your results show the net upfront extras, first-year recurring charges, estimated monthly ongoing cost and projected additional cost over the selected period. The optional comparison allows you to compare the upfront and recurring charges of another plot or new build development.

How the additional cost is calculated: Optional upgrades and other upfront expenses are added, while developer incentives and items already included in the advertised price are excluded or deducted. Recurring charges are projected using your selected annual increase. The property purchase price is shown for context but is not included in the calculated new build additional cost.

Calculator Disclaimer

The New Build Home Costs & Charges Planner provided by ADVAITH HOMES is for general information and budget planning only. It does not constitute legal, conveyancing, financial, mortgage, valuation or surveying advice.

Upfront new build costs: Reservation fees, developer upgrades, flooring, appliances, landscaping, parking, snagging inspections and additional legal or mortgage fees are indicative figures. Actual costs depend on the developer, property, plot, specification, location and purchase agreement. Confirm which items are included, optional, refundable or credited at completion.

Ongoing property charges: Service charges, estate management fees, communal heating costs, parking charges, amenity fees and projected increases are estimates based on the information entered. Actual liabilities depend on the lease, transfer deed, management arrangements, annual budgets and services provided.

Understanding the result: The property purchase price is shown for context and is not included in the additional-cost total. Items marked as included are excluded, while entered developer incentives are deducted. Future cost projections are illustrative and do not guarantee how charges will change.

Before making a financial commitment: Ask the developer for an itemised schedule of costs and confirm the figures with your solicitor or licensed conveyancer. The reservation agreement, lease or transfer deed, service-charge provisions and estate-management arrangements should be reviewed before exchange of contracts.
