Congratulations on completing your purchase. This guide covers everything you need to do in your first days and weeks as a homeowner: essential day one tasks (changing locks, meter readings, documenting the property), setting up utilities and council tax, understanding your responsibilities as a freeholder or leaseholder, home security, administrative registrations, and building good relationships with your neighbours. Whether you have bought a freehold house or a leasehold flat, this guide will help you get settled quickly and avoid the most common new owner mistakes.
Moving day is hectic, but there are several tasks that should be completed on day one. These protect you legally, financially, and practically.
New Build? Do a Snagging Inspection
If you have bought a new build, carry out a thorough snagging inspection within the first few days. Check for cosmetic defects (paint, plaster, tiling), functional issues (doors that stick, windows that do not seal properly), incomplete work, and anything that does not match the specification. Report all snagging items to the developer in writing. Your home should be covered by an NHBC or equivalent 10 year structural warranty.
| Task | Why It Matters |
|---|---|
| Change all external locks | You do not know who has copies of the existing keys. Previous owners, estate agents, cleaners, neighbours, and tradespeople may all have had access. A locksmith can usually change locks the same day for £100 to £200. |
| Take all meter readings | Record electricity, gas, and water meter readings and photograph them. This is the single most important financial task on day one. Without readings, you may be charged for the previous owner's usage. |
| Locate the stopcock | This is the internal water shut off valve, usually under the kitchen sink or in a downstairs cupboard. If a pipe bursts, you need to know where this is immediately. |
| Find the fuse box (consumer unit) | Usually near the front door, under the stairs, or in the garage. Know how to turn off individual circuits and the main switch. |
| Test heating and hot water | Run the boiler. Check radiators heat up. Run hot water. If anything fails, you want to know on day one while you can still easily contact the seller or their solicitor. |
| Check smoke and carbon monoxide alarms | Test every alarm. Replace batteries if needed. If there are no alarms, buy and install them immediately. You should have at least one smoke alarm on every floor and a carbon monoxide alarm in any room with a gas appliance. |
| Document the property | Walk through every room. Photograph any damage, missing fixtures, or anything that differs from what was agreed in the sale. This is important if you need to raise issues with the seller. |
Contact utility providers as soon as possible. You are responsible for all bills from the date of completion, even if you have not yet moved in.
You will automatically be supplied by the previous owner's provider, so the lights will work from day one. However, you should contact the existing supplier promptly and provide your meter readings. You can switch to a different supplier later once you are settled, but there is no rush. Comparison sites such as Uswitch, Compare the Market, and the Ofgem accredited services can help you find the best deal when you are ready.
Contact your local water company to register. Your water company is determined by your address and you cannot switch provider. Check whether your property is metered (you pay for what you use) or unmetered (you pay a fixed annual charge). If you are on a meter, take a reading on day one.
Contact your local council to register for council tax. You are liable from the date of completion. Set up a direct debit for monthly payments (typically over 10 months, April to January). If you are the only adult (aged 18 or over) living in the property, you qualify for a 25% single person discount. You must apply for this; it is not automatic.

If you need broadband from day one, arrange this before your move. New installations can take 2 to 4 weeks. Check which providers serve your address and what speeds are available. If the property already has a broadband connection, you may be able to take over the existing line for a faster setup.
You need a TV licence if you watch or record live television on any channel, or use BBC iPlayer. The current cost is £169.50 per year (standard colour licence). You can pay monthly by direct debit. Register at tvlicensing.co.uk. If you genuinely do not watch live TV or BBC iPlayer, you can declare this online, but you may be visited to verify.
Set up a Royal Mail redirection from your old address to your new one. This catches any post that has not been updated to your new address. Costs start at around £36 for 3 months, £51 for 6 months, or £68 for 12 months (prices may vary). You can set this up online at royalmail.com.
| Type | When | Notes |
|---|---|---|
| Buildings insurance | Must be active from exchange (your mortgage lender requires this) | If you have a leasehold flat, the freeholder's buildings insurance usually covers the structure. Check your lease and service charge. |
| Contents insurance | Arrange before or on moving day | Covers your belongings against theft, fire, flood, and accidental damage. Not legally required but strongly recommended. |
| Life insurance | Should already be in place if required by your mortgage lender | Check the policy is active and the sum insured matches your mortgage balance. |
Your responsibilities as a homeowner differ significantly depending on whether you own a freehold or leasehold property.
If you own the freehold, you own the building and the land it sits on outright. You are responsible for everything.
If you own a leasehold property (most commonly a flat), you own the right to live in the property for the term of the lease. The freeholder owns the building and the land.
| Your Responsibility | The Freeholder's Responsibility |
|---|---|
| Internal maintenance and repairs (inside your flat) | Structure of the building (roof, external walls, foundations) |
| Service charge payments (your share of building maintenance costs) | Common areas (hallways, lifts, stairwells) |
| Ground rent (if applicable to your lease) | Buildings insurance for the whole building |
| Complying with lease restrictions (pets, subletting, alterations) | Major repairs and maintenance of shared services |
Your service charge pays for the maintenance and management of the building and common areas. It typically covers building insurance, cleaning, gardening, lift maintenance, caretaker costs, and contributions to a reserve fund for major works. Your managing agent or freeholder should provide an annual breakdown. You have the right to challenge unreasonable charges.
New leases granted from 30 June 2022: ground rent is already set at a peppercorn (zero) under the Leasehold Reform (Ground Rent) Act 2022. You should not be paying ground rent on a new lease.
Existing leases (pre June 2022): ground rent is payable as specified in your lease. Some leases have fixed ground rent; others have escalating clauses that can significantly increase over time.
Proposed reforms (January 2026): the government published the draft Commonhold and Leasehold Reform Bill on 27 January 2026 proposing to cap ground rent at £250 per year for existing leases, reducing to a peppercorn (zero) after 40 years. The bill also proposes to abolish forfeiture (where a freeholder can seize your home for arrears as low as £350) and ban new leasehold flats. These proposals are not yet law; the bill must pass through Parliament first. If enacted, the ground rent cap could come into force in late 2028.
If your building has a managing agent, get their contact details on day one. Find out how to report maintenance issues, what the complaints process is, and who to contact in an emergency (such as a communal water leak or lift breakdown). Ask for a copy of the most recent service charge accounts and the current year's budget.
Good neighbour relationships make a significant difference to your quality of life. A little effort in the first week pays dividends for years.
Your solicitor should have covered boundary ownership in their report on title before completion. The T marks on the title plan indicate who is responsible for maintaining each boundary fence or wall. If a T appears on your side, you are responsible for that boundary. If there is no T mark, responsibility may be shared or unclear. Discuss shared boundaries and maintenance with your neighbours early to avoid disputes later.
Beyond changing the locks on day one, review the overall security of your property within the first week.
You need to update your address with a surprisingly large number of organisations. Work through this systematically to avoid missed post and potential security issues.
| Organisation | How to Update | Priority |
|---|---|---|
| DVLA (driving licence) | Online at gov.uk/change-address-driving-licence. Free. | Legally required |
| DVLA (vehicle registration) | Online at gov.uk/change-address-v5c. Free. | Legally required |
| Electoral roll | Contact your new local council or register online at gov.uk/register-to-vote. | Important for credit score |
| Bank and building society accounts | Online banking, phone, or in branch. | High |
| Credit card providers | Online or phone. | High |
| GP surgery | Register with a new GP near your new address. | High |
| Dentist | Register with a local dentist. | Medium |
| Employer and pension providers | Contact HR. | High |
| HMRC (self assessment if applicable) | Online at gov.uk. | High if applicable |
| Insurance providers (car, life, home) | Phone or online. Car insurance address affects your premium. | High |
| Subscriptions and deliveries | Update individually. | Medium |
Create a filing system (physical or digital) for your key property documents. You will need to refer to these throughout your time as a homeowner.
Write down these numbers and keep them somewhere visible (on the fridge or inside a kitchen cupboard). In an emergency, you need them immediately.
| Service | Number or Action |
|---|---|
| Gas emergency (smell of gas, suspected leak) | 0800 111 999 (National Gas Emergency Service). Available 24 hours. |
| Electricity emergency (power cut) | 105 (free from any phone). Your local distribution network operator. |
| Water emergency (burst pipe, flooding) | Your local water company's emergency number. Find it on their website or your bill. |
| Police (non emergency) | 101 |
| NHS (non emergency health advice) | 111 |
| Local plumber | Find a reliable local plumber before you need one. Ask neighbours for recommendations. |
| Local electrician | As above. Check they are registered with a competent person scheme. |
| Local locksmith | Keep a number saved in your phone. |
| Insurance claims line | On your policy documents. Save the number in your phone. |
| Managing agent (leasehold) | On your service charge correspondence. |
These are the mistakes that catch new homeowners out most often. Being aware of them will save you money and stress.
You should switch all utilities immediately for better deals
Focus on setting up accounts and providing meter readings first. You need to know your actual usage patterns before you can meaningfully compare deals. Wait until you have at least one month's usage data, then compare and switch if it makes sense.
The seller is responsible for any problems found after completion
Once completion has taken place, the property is yours. The legal principle is caveat emptor (buyer beware). Your recourse is limited unless the seller actively concealed a defect or misrepresented something in the property information form. This is why the snagging inspection and day one documentation are so important.
You do not need contents insurance if you have buildings insurance
Buildings insurance covers the structure. Contents insurance covers your belongings: furniture, electronics, clothing, and personal items. They are completely separate policies. Your mortgage lender requires buildings insurance but not contents insurance, though contents cover is strongly recommended.
Council tax is automatically set up when you buy a property
You must contact your local council and register. Council tax does not transfer automatically from the previous owner. If you do not register, you may face a backdated bill plus potential penalties.
Ground rent on a leasehold flat is always a small, fixed amount
Ground rent terms vary enormously between leases. Some are fixed at a nominal amount, others escalate with inflation, and some older leases contain doubling clauses that can make the property difficult to sell or mortgage. Check your lease carefully. The government has proposed capping ground rent at £250 per year (January 2026), but this is not yet law.
You own the boundary fence on the left side of your property
This is a common myth with no basis in law. Boundary responsibility is determined by the title deeds and the T marks on the title plan, not by any left or right convention. Your solicitor should have explained your boundary responsibilities in their report on title.
