Need a New Lock Fitted in Runcorn?
Eds Locksmiths Runcorn supplies and fits new locks on doors, windows, outbuildings and gates across Runcorn, including British Standard and high-security locks where an insurer asks for them. There is no call-out charge.
Four situations bring most people here: a door with no lock or only one, an upgrade to meet an insurance requirement, a new or replacement door that needs locks fitting, and an internal room, office, outbuilding or gate that needs securing.
Is It Fitting a New Lock or Replacing an Existing One?
When a door gains a lock it never had, or moves to a different type or standard, that is installation; when an existing lock is exchanged for an equivalent, that is replacement.
When a lock needs to be fitted
- you want a secondary lock on a patio or French door
- the door has been newly hung, replaced or is brand new
- you are upgrading to a British Standard or anti-snap lock
- an internal room, office, outbuilding, shed or side gate has no lock
- the door has no lock, or relies on a nightlatch when the insurer wants a deadlock fitted as well
We start with the door: what it is, where it is and how it will be used. A new lock may be appropriate if it lacks suitable locking hardware, needs another lock or has to give key-controlled access, and a freshly fitted door may require a compatible lock, cylinder, handles or other hardware. The door and frame must be checked before we can tell which lock types and positions may work, because material, thickness, construction and intended use set the specification. If the configuration allows it and another locking point is needed, an additional lock may be fitted, after we consider the existing hardware, fitting space and any written security requirements. Every recommendation covers the full door and lock arrangement.
If you need a lock replaced instead
Missing or stolen keys, a recent move, a worn lock or a forced door; for those, go to our lock replacement page.
Is Your Lock Actually Meeting Your Insurance Requirements?
"Insurance approved" is a phrase people attach to their locks without ever checking it. Most believe they are covered, and a meaningful number are not.
Two quick checks you can do now
Mortice locks on timber doors. Read the faceplate on the edge of the door: a kitemark and BS number should be stamped on it. A five-lever description alone does not confirm that a mortice lock meets BS 3621, and lots of generic five-lever locks lack any certification, often fitted before you moved in. Trust the certification and product markings over the lever count; the number of levers alone does not confirm that a lock meets BS 3621.
Euro cylinders on uPVC and composite doors. Look at the cylinder face for a star rating or Diamond mark. A basic cylinder resists snapping poorly, and snapping is a common attack on these doors. Cylinders are produced in various sizes and security ratings, and depending on the product, certification may include a TS 007 star rating or an SS 312 Diamond rating. It must also be compatible with the lock and sized correctly for the door, with its security considered alongside the handles, protective hardware and the full locking system.
Before we suggest a lock
Which lock is right depends on the door's construction, location, intended use and how people need to come and go, so a lock that suits one door may not suit another. We take into account whether the door is timber, uPVC, composite or aluminium, whether it is external or internal, its thickness, frame and existing preparation, how users need to enter and leave, and whether an additional lock or a complete locking arrangement is required. Those details help establish which lock types, sizes and fitting methods may be suitable, and any written instructions from an insurer, landlord or managing agent should be reviewed before the product is chosen.
| Standard or rating | Broadly indicates | Note |
|---|---|---|
| BS 3621 | Tested, thief-resistant single-point lock using a key from both sides | Commonly connected with suitable external timber doors |
| BS 8621 | Tested, thief-resistant single-point lock using a key outside, with keyless exit inside | May be relevant where egress without a key is required |
| TS 007 / SS 312 | Ratings for cylinders and connected door hardware | The rating depends on the door and any documented requirement |
What applies depends on the complete door arrangement and how the property is used. The following section explains the extra consideration needed for fire doors, flat entrances and communal doors.
Have you received a security requirement in writing from someone? Send it to us before the installation. We can suggest options that may match what the specification states, and your insurer, landlord or managing agent must then confirm that the proposal meets their requirement. For more on cylinders, see our anti-snap locks guide and uPVC door locks page.
Locks We Fit on Runcorn Properties
Lock installation covers far more than front doors. In each case the appropriate lock depends on what the door is made of, how much fitting space there is, how it needs to be operated and whether any security requirement has been confirmed.
The mortice deadlock
Set into the door edge, mortice deadlocks and sashlocks suit suitable timber doors, and certified versions exist where a recognised standard is required. Initial checks are needed to establish the door's thickness and construction and assess its frame and the fitting position. Fitting one where there was none means cutting the door, which is skilled work.
Nightlatches and rim locks
Fitted to the surface on the inside of a suitable door, nightlatches (the Yale-style lock) come in models with different entry, exit and deadlocking options. Whether one should be the primary or additional lock depends on the door, product specification and intended use; on final exit doors, a mortice deadlock usually goes alongside it.
Euro cylinders and upgrading to anti-snap
These work within compatible lock cases and multipoint systems, which lock uPVC, composite and some aluminium or timber doors at several points. Correct sizing and compatibility with the lock and protective hardware are essential, and various security ratings can be supplied where required. We can assess compatible cylinders, handles and locking parts in an existing multipoint system, with the scope set by the door design and component compatibility.
Gate, outbuilding and internal locks
Key-operated or privacy locks can be fitted to bedrooms, offices, stockrooms and stores. The right one depends on construction, frequency of use, the privacy needed and who should have a key. A locked side gate or shed also protects a rear door that is out of sight.
The window locks
Under some policies, accessible windows need key-operated locks.
Give us the door details, its location and what needs securing on the call, and we will discuss options and price the job. The price stays as given unless the work differs on site; we explain any change before work starts. See window locks, compare common door lock types and.
Which Standard Applies to Your Door? BS 3621, BS 8621 and PAS 3621
Choosing between the three standards starts with one question: does anyone need to get out through this door without a key? If not, BS 3621, key-operated from both inside and outside, is the common requirement for a timber final exit door. If they do, as on escape routes in flats and HMOs, BS 8621 gives a thumbturn inside for keyless egress. On uPVC and composite doors with multipoint locking, PAS 3621 is the equivalent standard.
| Standard | Inside operation | Door type |
|---|---|---|
| BS 3621 | Key | Timber, final exit |
| BS 8621 | Thumbturn | Flat, HMO or escape route |
| PAS 3621 | Multipoint equivalent | uPVC or composite |
Be wary of the phrase "insurance approved". BSI certifies the standard and individual insurers set their own requirements. Many of the largest UK insurers take guidance from RISCAuthority, but there is no single standard all of them follow, and each sets its own conditions. Some policies specify a standard, so the wording of yours is what counts.
Fire, flat and communal doors Here the lock must be compatible with the door's fire-safety and escape requirements, and the installation must not stop the door closing correctly or affect its resistance to the spread of fire and smoke. The work must keep fire and smoke resistance, the door, frame and essential seals, effective self-closing, keyless exit where required and safe access for other occupants.
Approval may be required if the door is part of a rented or leasehold property, a flat in a managed building, a communal entrance or shared area, or a designated fire or escape-route door. Check with the landlord, freeholder, managing agent or other responsible person before arranging any alteration, and include any approval, fire-door information or required hardware specification in your enquiry. If the door's status or needs are unclear, a competent fire-safety professional may have to advise.

The Cost of Fitting a New Lock: What Affects It
Expect the price to reflect three things: which lock is chosen, what the door is like, and the preparation the door needs. You are never charged a call-out, and the price is given to you during the call. You pay for the work carried out, any parts needed, and VAT. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged.
Factors that affect the cost
- The lock: type, size, security rating and any additional hardware.
- The door: material, existing openings and any work needed on the door or frame. Installing where there was no lock before is slower than replacing one, because the door has to be prepared first.
- The job: how many locks and doors, the fitting complexity and the appointment conditions, including the time of day.
Describe your requirements and, if you can, provide photographs showing the door and the hardware already fitted.
The process
A price based on your description comes on the call and holds unless the job differs on site; any inspection, your approval and installation follow. Here is what happens between choosing a lock and testing the completed installation. 1. Let us know what the door is made from, where it is situated and how it is intended to be used. 2. Add photographs of the door, frame and hardware, and any written requirements. 3. We outline suitable options and price the job on the call from your description. 4. Before any work begins, we agree the specification and work and explain any change to your price. 5. We fit the lock in the agreed spot, then test it, the keys, relevant hardware and door operation.

Lock Fitting Across Runcorn
Fitting is booked work, so visits are arranged for a weekday between 7am and 6pm for homeowners, landlords, letting agents and business premises. We fit locks anywhere in WA7, from Murdishaw, Westfield and Halton Brook to Dukesfield, The Brow and Weston Point, and in the parts of WA4 around Runcorn, which lie mostly in Warrington.
What needs fitting depends on the building. Runcorn's 27,226 households are 35.7% terraced, 34.0% semi-detached, 18.5% detached and 11.6% flats (Census 2021, ONS); Grange, The Brow and Murdishaw are mostly houses, which usually means a front and a back door to look at first. By age, 50.1% of homes date from 1945 to 1982, 19.9% from 1983 to 2008, 11.4% from 2009 on, 9.6% from 1900 to 1939 and 8.8% from before 1900 (VOA council tax property stock, 31 March 2026), so a visit often means checking an older lock against what a policy asks for as well as fitting a new one.
Halton, Higher Runcorn and Weston Village are conservation areas (planning.data.gov.uk, October 2026). Fitting a lock does not alter that; the national dataset does not show whether any Article 4 direction restricts doors or windows, so ask the council before changing the door itself. See all areas we cover.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.
What We Fitted: Proof for Your Insurer
Good paperwork is part of a good installation. Your record helps with future maintenance and replacement parts and belongs with your property documents, but its biggest value may come if you ever claim: an insurer may ask what was fitted and whether it met the policy, and memory is no substitute for a written record.
What the record covers - Lock details: available information on the fitted lock, cylinder or hardware - Keys and operation: supplied keys passed to you, and the lock's operation checked at completion
We suggest storing it alongside your policy so it can be found quickly.
How a Job Works
What happens once you get in touch:
- You describe the door type, its position and the result you want, and send over anything in writing that your insurer, landlord or managing agent has asked for.
- We agree a suitable lock and price the job from your description when you call, arranging an inspection if needed; the price remains unless the job differs on site, and any change is explained before work starts.
- You receive the keys and a record of what was installed.

Frequently Asked Questions
How do I know if my lock meets my insurance policy?
Read the lock, then read the policy. On the edge of a timber door, the faceplate of a compliant mortice lock carries a kitemark and BS number. On uPVC or composite doors, check the cylinder face for a star rating or Diamond mark. No marking means you have no evidence the lock meets the standard. The policy's security section tells you which standard it wants.
I have a five-lever lock. Is that enough?
That depends on its certification, not its levers. The number of levers alone does not confirm that a lock meets BS 3621. Generic five-lever mortice locks are widely sold in DIY shops without the kitemark, and many are fitted by previous owners or budget refits. Look for the kitemark and BS number on the faceplate; without them, treat the lock as uncertified.
Can you fit a lock to a door that does not have one?
Certainly. Fitting a lock to a door without one starts with checking the door and frame, then preparing the door, generally by cutting a mortice pocket or boring for a cylinder depending on the lock and door. It takes longer than a swap and needs a skilled hand, especially on composite doors, which damage easily if the cut is wrong.
What is the difference between BS 3621 and BS 8621?
BS 8621 adds keyless exit. Like BS 3621, it covers thief-resistant single-point locks, but where a BS 3621 lock is operated by key from both sides, a BS 8621 lock takes a key outside and a thumbturn inside, so nobody needs a key to leave, as on escape routes in flats and HMOs. PAS 3621 covers equivalent multipoint systems on uPVC and composite doors. Door, property use, fire strategy and means-of-escape requirements decide which fits.
Why do different insurers ask for different locks?
Because there is no single standard every UK insurer follows. Many of the largest insurers take guidance from RISCAuthority, but each one sets its own policy conditions, so two similar houses can be asked for different locks. Read the security section of your policy wording, and if anything is unclear, ask your insurer to confirm in writing. Send us that wording and we can discuss products that may match it.
Will you give me proof of what was fitted?
If you ever have to claim, the insurer may ask what locks were on the doors and whether they met the policy, and being able to show a written record is far better than relying on memory.
Should I buy the lock myself and just pay you to fit it?
We would usually advise against it. Share the door details and any policy wording, and we can recommend a lock that may meet the requirement before you buy anything.
How much does it cost to have a new lock fitted in Runcorn?
It depends on whether the door is already prepared or has to be cut, the lock type and security rating, the door material, how many doors, and the time of day. Fitting into a door with no existing provision takes longer than swapping a like-for-like lock. Describe the door when you call and you get a price that holds unless the job on site differs, in which case you are told first. No call-out charge.
