Property Running Costs — What to Budget For
Understand the real monthly cost of owning a property beyond the mortgage. Enter figures from authoritative sources and we'll add them up for you.

Enter annual amounts for each cost category. See the sections below for typical ranges and the authoritative source to check each figure. Leave blank what you don't know — we'll add up what you have.
Totals update as you type. This is a simple sum — the accuracy of your total depends on the accuracy of your inputs.
The mortgage payment is just the beginning. Council tax, energy, insurance, water and maintenance can easily add another £500–£900 per month for an average family home — sometimes considerably more. Knowing the full picture before you buy prevents surprises after you've moved in.
The Six Main Running Costs
Below is each category with a typical UK range and the authoritative source to check for your specific property. Use the tool above to add up your own totals.
Council Tax
Typical £1,400–£4,000/yrSet by your local authority based on the property's band (A–H) and reviewed each April. A Band D property in England averages around £2,300–£2,500 per year. Scotland and Wales have their own systems (LBTT authorities / WRC). Single-person households get a 25% discount.
Check the official band and your authority's current rate on GOV.UK →Energy (Gas & Electricity)
Typical £1,200–£2,500/yrDepends on property size, insulation (EPC rating) and heating type. An EPC C 3-bed typically sits around £1,500–£1,900; an EPC F–G property of the same size can be £2,500+. Ofgem's price cap sets unit rates each quarter — your actual bill depends on usage.

Typical £400–£700/yrBilled separately from council tax. Metered bills depend on occupancy and usage; unmetered bills are based on rateable value and the area's water company tariff. Rates vary significantly between companies — South West Water typically highest, Severn Trent and Yorkshire Water typically lowest.
Compare water bills on the Consumer Council for Water →Buildings & Contents Insurance
Typical £200–£600/yr combinedBuildings insurance is required by most mortgage lenders from exchange of contracts. Cost depends on rebuild value (not market value), location, construction type, and claims history. Flood-risk and subsidence-history properties pay significantly more. Contents insurance is optional but usually sensible.
MoneyHelper's buildings insurance guide →Maintenance Reserve
Typical 1–2% of property value/yrMoney set aside each year for repairs and upkeep — boiler servicing, redecoration, replacing the roof eventually. A common guideline for older homes is 1–2% of the property value per year; 0.5% for modern new-builds under warranty. This is a buffer, not a bill — but it's the difference between manageable and painful when something fails.
MoneyHelper guide to the cost of buying & owning →Service Charge & Ground Rent (leasehold only)
Typical £1,000–£5,000+/yrApplies to leasehold flats and some leasehold houses. Service charge covers maintenance of the building and communal areas — varies enormously between developments. Ground rent is a smaller annual charge payable to the freeholder. Always ask for the last three years of service charge accounts before exchange, and check whether any major works (roof, lifts, cladding remediation) are planned.
LEASE — the free government-funded leasehold advisory service →The ranges above are broad guides based on typical UK averages. Actual costs depend on property type, size, location, efficiency, and personal usage patterns. Always check the authoritative source linked in each category for the figure that applies to the specific property you're considering.
How to Research Each Cost for a Specific Property
Before making an offer, spend 30 minutes gathering real figures for each category:
- Council tax: Look up the band on GOV.UK and the current rate on the local council's website.
- Energy: Ask the seller for the last 12 months of bills, or look at the EPC — it includes indicative annual costs.
- Water: Identify the local water company and check whether the property is metered. Most company websites have a running-cost calculator.
- Insurance: Get online quotes before you exchange — sites like Compare the Market and MoneySuperMarket give representative figures in minutes.
- Leasehold: Request the last three years of service charge accounts and the ground rent clause from the lease. Red flags include rapidly rising service charges or planned major works.
Sellers (and their agents) should be able to provide recent utility bills and service charge accounts without issue. If they're reluctant or unable to, ask yourself why.
How a Survey Can Affect Running Costs
A RICS Home Survey directly affects what you'll pay to run a property. Issues a survey might flag — poor insulation, an ageing boiler, failing roof, damp — are future maintenance liabilities that feed straight into your running costs.
Knowing about them before you exchange gives you three options:
- Renegotiate the purchase price to reflect the cost of remedial work
- Ask the seller to carry out repairs before completion
- Walk away if the costs make the purchase unviable
Without a survey, these costs become your problem the moment you complete. A Level 2 or Level 3 survey — and our optional Schedule of Estimated Repair Costs — turns unknown future spending into a known starting position.
Know the True Cost Before You Commit
A RICS Home Survey identifies defects that become your future running costs. CJ Bloor covers the North West, West Yorkshire and West Midlands.

Figures and ranges are broad typical values — always check the authoritative source for each cost category (GOV.UK for council tax, Ofgem for energy, the specific water company for water rates, your insurer for insurance premiums, the lease and managing agent for service charges). Maintenance guidelines are indicative only — actual maintenance spend varies widely by property.
