Designing your scheme

Obtaining and understanding your quote, list of contractors, estimating costs.

As part of the application process you will be asked to obtain quotes for your gates. The following guide is to help you understanding the specification of the gates and the options that are available to you.

Please also refer to our: Alley Gating Scheme - Glossary of terms [2Mb].

Alley Gate example

The gates that the contractors will quote you for will have the following features.


  • Gates should have a total height should be of no more than two metres from the ground. This includes the height of finials or any other additions of trimmings.
  • Gates should be installed at least one metre away from the closest edge of the highway to prevent the need for planning permission. Where possible they should be visible from the street.
  • The design should be, as far as possible, resistant to climbing and forcing, and should allow clear vision and not be clad. Hinges used must not offer a foothold to potential burglars. In addition, it should not be possible to lift the gate out of its frame.
  • The gap between the gate and the ground should be small enough to prevent potential burglars from crawling underneath.
  • All gates should be fitted with a drop bolt so that they can be secured open as required.
  • No handles should be fitted to any of the locks or the gates themselves.
  • Wherever possible a single leaf gate should be installed in preference to a pair of gates.
  • Gates should  open 'into' the alley and not 'out' towards the highway
  • Gates should slam shut.


  • The gate should be topped with blunted spikes or finials (see glossary of terms).
  • Vertical bars should be spaced no wider than 100mm apart.
  • The sides of the frame should be fixed to the wall or galvanised steel posts through the galvanised frame with heavy-duty fixings. The fixing should be visible and accessible when the gate is open.
  • All gate components should be welded.

Materials used

  • 3mm steel should be used for all sections.
  • The steel should be galvanised to protect from rust, leaving a grey finish.


  • A narrow-style, Euro-profile automatic deadlocking mortice latch should normally be used. Any proposed variation must be subject to approval. This means that they will "slam- to- lock".
  • The same lock should be fitted to all gates in the scheme unless otherwise instructed.
  • Locks should be embedded into the post of the gate.


  • The scheme will allow for the purchase of 1 key per household.
  • In most cases the keys are supplied are of a standard "Yale" type which can be easily cut at High Street kiosks. However, if making copies you are advised to ensure that whoever cuts the keys is using the correct shaped template as this can affect how well the key engages with the lock.
  • In cases where this is a very large number of households who will be using the gates, 'security' keys may be advised. This can only be copied by the original locksmith and will prevent keys being given freely to those who live outside the scheme. These keys are more expensive to purchase and copies can only be obtained though the original contacts. Contractors will be able to give you more information on this if you wish to consider this measure.
  • In both cases, you may wish to purchase additional keys from the contractor up front. If so, please state this on your application form and these added to the order the council raises for the gates. You will be advised how this affects your residents' contribution.

Estimating costs

When you approach your neighbours to get their consent for a scheme, it is likely that they will be interested in how much the scheme will cost. This guidance shows you how to estimate how much a scheme is likely to cost per household once you have received a quote.

Please note: VAT does not need to be added to your figures and most quotes will not add this.

  • Total up the full cost of the gates (this may already be done for you on the quote).
  • Identify the cost per key and multiply this by the number of households in your scheme.
  • Identify  the cost in of any extra services or miscellaneous items (except finials or powder coating).
  • Add the costs together  for all of the three items above to give you a total cost.
  • Divide this by 10. This will give you the total cost of the residents' contribution.
  • Add on the full cost of any finials, powder coating or additional keys.

Divide this figure by the number of households to get contribution per house for the installation. It is recommended that you add a small amount to this figure so that this can remain in the gating scheme bank account and establishes a sinking fund for future repairs and maintenance.

Approximate costs for items in year 2016/17

(These should be used as a guide only, quotes should still be sought for all applications.)

  • Gates £1,450 each
  • Keys £4.50 each
  • Lock box £75 each
  • Powder coating £400 per gate
