Need someone tonight in W1, SW1 or the City?
Yes. All Services 4U answers the phone at any hour, and we send locksmiths to addresses across Westminster and the City of London day and night.
How soon can a locksmith get to a Central London address?
It depends where the nearest locksmith's last job was, so the time is worked out on the call, once we know who is free, rather than quoted as a standard figure. You hear it before you agree to anything.
Give us the postcode and the nearest street corner or building name. In a block, say which floor and whether a porter or entry phone stands between the street and your flat.
Is there anyone in the building who could let me in first?
Possibly, and it costs nothing to ask while you wait.
- A porter, concierge or estate office: if your building has one, ask there first. On the Barbican, the City of London Corporation tells residents to notify the concierge about repairs out of hours.
- Your letting agent: more than half of households in Marylebone and Bayswater rent privately, and an agent may hold a spare key. Try its out-of-hours line.
- Only shut out of the street door? A neighbour can buzz you into the hallway; that needs no locksmith.
- Nobody answers? Ring us; you have lost nothing by trying first.
My ID and keys are inside the flat. How do I show I live here?
Proof that you live there is needed before the door is opened, so gather what you can reach from outside: a bill, a bank letter or a tenancy agreement in your email or on your phone. In a block, the porter or concierge may know you by sight, and a letting agent holds your tenancy. Tell us on the call what you have, before anyone sets off.
You ring
Calls are answered 24 hours a day. Our locksmiths travel from their last job, not a depot, so on the call we tell you when the nearest one can reach you.
- Calls answered every day, 24 hours
- Live updates on the arrival time
We ask
Which door you are outside, whether you own or rent, what has happened, and what the lock looks like.
We quote in writing
Before work starts: the labour time we expect, named parts with the lock's make and standard, VAT and an estimated total. If the job changes or will run over, we stop and quote again.
At your door
Our locksmith shows ID, and we always ask for proof that you live at the address before a door is opened.
Afterwards
You get an itemised report of the job, and our labour is guaranteed for six months against faulty workmanship.
Who should ring us, and who should ring someone else
We take calls from tenants, owners, landlords, managing agents and small businesses locked out of a home or business premises, or with a lock that has failed or been forced.
Locked out of a car
For a car lockout, our auto locksmith service has its own page; this page covers homes and business premises.
A smart lock
Fitting a smart lock is planned work, not an emergency: our smart lock page covers it.
Lockout prices in Central London, and the low phone quote to distrust
All Services 4U publishes its hourly labour rate, charges no call-out fee and puts the quote in writing before work begins, so you can check the figure before anyone touches the door.
How much is a locksmith in Central London, and is it more at night?
Yes, nights cost more. All Services 4U charges £59 an hour on weekdays between 7am and 6pm and £69 an hour at all other times, evenings, nights and weekends included, both plus VAT (£70.80 and £82.80). There is no call-out charge, and the minimum is one hour of labour, then 15-minute steps.
Parking, travelling, fuel and congestion are not charged, which matters in the middle of London.
A new cylinder or a door repair, if one is needed, is priced separately on the written quote, which lists the expected hours, named parts, VAT and an estimated total. If the job grows, the locksmith stops and quotes again.
Work out the labour cost
We charge labour by the hour, with a one-hour minimum and 15-minute steps after that. Choose when you need the locksmith and how long the job takes; your locksmith tells you the expected time before starting.
Labour £59.00 + VAT £11.80 = £70.80
Labour only. Parts, such as a replacement cylinder, and any door or frame repair are quoted separately, in writing, before work starts. No call-out charge.
| Item | Price | How it is charged |
|---|---|---|
| Opening a locked door | Our hourly rate | If the door cannot be opened without damage, you may also need to pay for a replacement lock or a door repair |
| Labour, weekdays 7am to 6pm | £59 an hour (£70.80 with VAT) | Opening a door or changing a lock |
| Labour, evenings, nights and weekends | £69 an hour (£82.80 with VAT) | Monday to Friday 6pm to 12am, every day 12am to 7am, and all day Saturday and Sunday. Opening a door or changing a lock |
| Minimum charge | One hour of labour | Any further time is billed in 15-minute increments |
| Call-out | No call-out charges | Free quotes |
| Travelling, parking, fuel or congestion | No charge | We do not charge for parking, travelling, fuel or congestion |
| Parts: the named lock or cylinder | Quoted separately | The make, and the standard it meets, written on the quote |
| Anything beyond opening the door | Its own price | Marked as an extra |
| VAT | Subject to VAT | Shown on the written quote, before we start work |
| Payment | Cash or credit card | Paid to the engineer, on the invoice |
Someone quoted me a very low price on the phone. Should I worry?
Treat it with care. Which?, in an April 2024 report, says "Locksmiths aren’t regulated", and names "bait and switch pricing, where you’re quoted a low price that is inflated after the locksmith arrives at your home" as a common scam.
Before anyone sets off, ask for the firm's name and where it is based, an estimated total split into labour, parts and VAT, that figure in writing before work starts, who pays if the door or frame is damaged, and the name of the person coming.
To answer the first for ourselves: All Service 4 U Limited, Companies House 07565878. Our head office is in East Barnet, north London, and our locksmiths are based and work locally. We are not members of the Master Locksmiths Association; our ISO and SafeContractor certificates can be checked with their issuers (how to check them).
Four things move the price
Four things move the price
Four things change what a locksmith job costs: the time of day, the lock and the door, any damage, and parts.
- The time you need the door openedAn evening, weekend or night call is priced differently from a daytime one, so ask which rate applies.
- The lock and the doorA standard latch opens differently from an anti-snap cylinder or a multi-point UPVC lock.
- DamageA snapped key, a forced door or a seized mechanism adds work.
- PartsA replacement cylinder or lock body is a cost separate from opening the door.
A locksmith quote that does not separate time, lock, damage and parts is harder to check. The protection is the one question you can ask: what is the estimated total, and will the locksmith stop and tell you before it goes over?
Ring for the rate and a written quote
Tell All Services 4U the address and which door. The quote comes in writing, by text or email, before any work starts.
Porters, entry phones and mansion-block doors
In Central London the locked door is often the building's, not yours. Census 2021 puts 70.2% of Westminster households and 87.0% of City of London households in purpose-built blocks, and another 16.1% of Westminster households in converted or shared houses. Tell us which door you are stuck at, because a different person can say yes to each.
- On the street
The building's front door
Usually the freeholder's, with the managing agent or residents' company deciding on any work to it. Have their name ready when you ring.
- Lobby and corridors
Entry phones and corridor doors
These serve every flat, so changes need the managing agent's agreement. A porter or concierge, where the block has one, can tell you how to reach the agent at night.
- Your flat
Your own front door
Owners decide, within what the lease allows. In a rented flat, any new lock is for the landlord or agent to agree.
You own the flat
Ring us with the postcode and say which door is shut. If it is the building's, see who opens the street door.
You rent privately
Ring us; try your letting agent's out-of-hours line too. Opening the door and changing the lock.
Westminster council or Barbican
Lost keys are yours to arrange or pay for. Westminster's emergency line is 0800 358 3783; Barbican Property Services 020 7029 3909. Who pays when keys are lost.
You let or manage the flat
Ring or send the property details. Westminster's licence and a lock change between tenants.
Office, shop or restaurant
Same number, any hour. Seized locks and failed exit buttons.
I can't get past the street door or the entry phone. Who can open it?
Whoever runs the building: a managing agent, the freeholder or a residents' management company. A locksmith works on a shared door only with their agreement, so ring them or the building's out-of-hours number first, or ask a neighbour to buzz you in.
If none of them answers, tell us which applies and we tell you what we can do.
I rent privately. Will you open my flat, and can you change the lock?
We open it once you have shown that you live there.
A new lock changes the landlord's property, so agree it with the landlord or agent first, and check what your tenancy agreement says about locks and keys.
I let a flat in Westminster. Is there anything to know before changing the locks between tenants?
Check first whether your flat needs a licence. Westminster City Council says "Privately rented homes in 15 wards will need a licence from 24 November 2025"; its scheme "covers 15 of the city’s 18 wards", and "Pimlico South", "St James’" and "Vincent Square" are the three wards outside it (do I need a licence?). For the lock change itself, give us the address and the reason; the itemised report records what was fitted, for your property file.
My flat door is a fire door. Can the lock still be changed?
Ask the managing agent before a fire door is drilled or given a new lock. Westminster City Council's Tenant Handbook tells its tenants not to remove door closers fitted for fire safety, and says "Don’t fit locks or obstruct escape routes." Our fire door inspection and fire door repair pages cover that work.
How often a block's fire doors must be checked
Regulation 10 of the Fire Safety (England) Regulations 2022 says the responsible person for a building "which contains two or more sets of domestic premises and which is above 11 metres in height, must use best endeavours to undertake checks of fire doors at the entrances of individual domestic premises in the building at least every 12 months", and must check communal fire doors "at least every 3 months".
Westminster council flats and the Barbican: who pays when keys are lost
If the council or the City of London Corporation is your landlord, read its rule before you ring anyone. Westminster makes lockouts its tenants' job, and the Barbican recharges tenants and leaseholders for lock changes after lost keys. Social renting runs from 10.9% of households around Marylebone to 57.8% around Lisson Grove and Church Street.
I'm a Westminster council tenant and I'm locked out. Will the council come?
Lockouts are yours to arrange. Westminster City Council's Tenant Handbook lists "Getting extra keys cut; replacement locks if keys are lost and lockouts" among the repairs tenants are responsible for, along with "Top locks (Yale)".
The council does treat "Break-ins where property is unsecure and no secondary means of locking" as an immediate repair. For that, ring its emergency repairs line, 0800 358 3783. The same handbook says "Residents must not replace their flat entrance door", so check with the council before any work goes beyond the lock.
I live on the Barbican and I've lost my keys. Does the estate office change the lock?
Expect to pay for it. The City of London Corporation's Barbican repairs page says "Both City of London tenants and the leaseholders will be recharged for lock changes if they lose their keys." It adds that "The estate office will not arrange for the lock changes for Chubb and other security locks which always remains the responsibility of residents."
Property Services is on 020 7029 3909; out of hours, the page says to notify your concierge. Tenants on other City of London Corporation estates report repairs on 0800 035 0003, "24 hours, seven days a week."
Housing association tenants should ring their own association's repairs line first. If the lock is yours to arrange, ring All Services 4U; the written quote names the lock's make and standard, so you can check it against what your landlord allows.
What the itemised report records
- What we fixed The work, in plain words.
- Is it safe Yes, or where things stand with the door.

Our labour is guaranteed for six months

Our guarantee covers labour for faulty workmanship for six months from the date of completion.
- It is void if our work is misused or neglected by anyone else, or repaired, modified or tampered with by anyone other than an All Services 4U engineer.
- It does not cover materials you supply or consequential damage.
- Keep your invoice: the six months run from the date the work was completed.
The full terms are on our locksmith guarantee page.
Parts we fit carry the manufacturer's warranty.
Lost keys in a council or Barbican flat? Ring us for the lock
Tell us the estate or block and the lock on the door. The written quote names the make and standard before any work starts.
Offices, shops and restaurants: seized locks and failed exit buttons
Businesses in the West End and the City ring the same number, 020 3627 0820, at any hour. Both locksmith jobs All Services 4U has written up in Central London were for businesses.
Our keys keep snapping in a lock at work. Repair it or replace it?
Keys that keep breaking can mean the cylinder is failing, not the keys. At a commercial storage unit in Soho (W1D), several keys had broken inside the lock; our locksmith found the cylinder had seized, removed the old lock and fitted a new one in a single visit.
Read the Soho storage unit job.
Staff can't open a magnetically locked door from inside. What now?
Ring straight away and tell us which part has failed, if you know. At Audley House in Victoria (SW1E), the exit push button on a magnetically locked door had failed, so occupants could not release the door from inside; our engineer replaced the button and tested the circuit on 15 January 2026, in one visit.

Locksmith services in Central London from All Services 4U
All Services 4U is a locksmith and property maintenance company. We handle eight kinds of locksmith job. Opening a door and changing a lock are charged at our published hourly rate; other work, and any parts, are quoted before they start.
Locked out: emergency entry
We answer calls at any hour and open locked doors on homes and businesses. Non-destructive entry, which leaves the lock in place where it can be done, is one of our services.
Lock changes
We change locks after a move, a lost key or a tenant leaving, and write the make and standard of the new lock on the quote.
Lost keys
When every key is lost, we can open the door and, if you choose, change the lock so the lost keys no longer work; each is quoted first.
Broken key extraction
We remove a key snapped in the lock and quote any repair to the lock before starting it.
Lock and door repairs
We repair failed locks and UPVC multi-point mechanisms, and repair UPVC and timber doors when the lock is not the only damage.
Burglary repair and boarding up
After a break-in we quote the work the door needs: a replacement lock, a temporary repair or boarding up. Report the crime to the police first.
Landlords and managing agents
We change locks for landlords and agents, including after a bailiff-led eviction, and leave an itemised report for the property file.
Shops, offices and other premises
We handle office and shop lockouts, restricted master key systems, panic bars and access control for businesses.
Listed buildings and doors older than 1930
If your building is listed, ask before any work that goes beyond the lock itself. Westminster City Council says listed building consent "is required for any works to a listed building that would affect its special architectural or historic interest", and that it is "a criminal offence" to carry out such works without consent, "even if you did not know that the building was listed."
That covers a lot of Central London: the council counts "around 11,000 buildings and other structures in Westminster" on the list and 56 conservation areas, and the City of London has "more than 600 listed buildings" and 28 conservation areas.
My flat is in a listed building. What should I check before work on the door?
Tell us on the call that the building is listed. Consent turns on whether the work affects the building's special interest, and the council says it "covers all parts of the building (interior and exterior)". If a job would mean cutting into an original door or replacing it, ask the owner or the council first; the written quote shows exactly what would be done to the door.
My building is older than 1930. What should I tell the locksmith?
Describe the door and every lock on it: what kind of key it takes, where each keyhole sits, and whether the door is timber or a later replacement. Old buildings are common here: more than six in ten homes with an energy certificate in Bayswater (69.6%), Marylebone (62.8%) and Maida Vale (62.5%) were built before 1930, against 0.9% in the City. Whether a lock opens without damage depends on the lock itself, and the quote says who is responsible for any damage to the door or frame.
Lock standards: BS 3621, TS 007 and PAS 24
Every All Services 4U quote names the lock and the standard it meets. Secured by Design calls BS 3621 "the minimum standard for locks on external or entrance doors", and Union, a lock maker, says "Most insurance policies will require a property to have BS3621 locks on all ground floor external locks".
Union adds that "Multi-point locks comply to a different standard", and your own policy wording sets what your insurer requires, so read it before you choose a lock.
BS 3621, TS 007 and PAS 24, one by one
BS 3621:2017
Lock assemblies operated by key from both the inside and the outside of the door. Union says the easiest way to tell if a lock meets it is the Kitemark symbol on the faceplate.
Where it applies: Locks on external and entrance doors
TS 007
The Door and Hardware Federation's enhanced security requirements for replacement cylinders and associated security hardware, as Secured by Design describes it.
Where it applies: Replacement cylinders
PAS 24
In Secured by Design's words, "New door assemblies are covered by PAS 24".
Where it applies: New door assemblies
Lock brands we fit
We fit locks and cylinders from Yale, Chubb, ERA, Union, Mul-T-Lock, Banham, Brisant Secure, ABUS and Legge.
Westminster and the City of London: the neighbourhoods we cover
We send locksmiths day and night across the City of Westminster and the City of London, from Paddington and Maida Vale to Pimlico, Mayfair and the Barbican. That takes in the W1, W2, W9, NW1, NW8, SW1 and WC2 districts and EC1 to EC4, and runs into the neighbouring boroughs of Camden, Islington, Kensington and Chelsea, Lambeth and Southwark.
Eleven Central London neighbourhoods in figures
| Area | Households in flats | Renting privately | Social rented | Homes built before 1930 |
|---|---|---|---|---|
| Soho | 97.5% | 51.8% | 27.8% | 45.2% |
| Mayfair and Covent Garden | 94.9% | 51.9% | 23.9% | 59.4% |
| Marylebone | 87.9% | 57.4% | 10.9% | 62.8% |
| Westminster and Victoria | 94.9% | 43.5% | 28.9% | 27.1% |
| Pimlico | 90.1% | 41.2% | 27.4% | 57.2% |
| Paddington | 87.4% | 53.6% | 16.3% | 22.6% |
| Bayswater | 92.5% | 58.3% | 13.4% | 69.6% |
| Maida Vale | 94.6% | 48.3% | 17.3% | 62.5% |
| St John's Wood | 85.1% | 47.8% | 12.9% | 28.4% |
| Lisson Grove and Church Street | 96.0% | 26.2% | 57.8% | 16.0% |
| Barbican and the City | 98.0% | 48.3% | 14.9% | 0.9% |
Households, flats and tenure are Census 2021 figures for the neighbourhood (MSOA) that holds a representative postcode for each place, a mapping rather than an official boundary; Mayfair and Covent Garden share one, as do the Barbican and the rest of the City. Building age comes from energy performance certificates, which cover only homes that have one.

Which certificates does All Services 4U hold, and how do I check them?
At All Services 4U, we hold ISO 9001:2015 (certificate GB-Q265-1), ISO 14001:2015 (EM-1102) and ISO 45001:2018 (HS-1102) certificates and SafeContractor approval (SY1948). We also hold Once For All Health & Safety and Constructionline Gold, and we are NICEIC approved for our electrical work. Ask us for a copy of any certificate and we send it.
Are locksmiths regulated in the UK, and is All Services 4U MLA approved?
Locksmiths are not regulated by the Government in the UK, and All Services 4U is not a member of the Master Locksmiths Association (MLA). The MLA, the trade's voluntary body, says "the locksmithing industry is not regulated in any way by the Government in the United Kingdom".
