Personal Search Agents

From Monday 11th March, we will be implementing a charge for the personal search proccess. You will always have the option to obtain the information for free directly from the Freedom of Information Officer of each of our owning councils.

After registration on the portal (and you will already be registered if you are an existing user), you will be taken through the payments process to enable you to pay by card for the search(es) you require.  There is a discount for volume users and the fees are:
1 – 49 searches = £7.50 each
50 – 99 searches = £7.25 each
100+ searches = £7.00 each

When paying in advance the software will remember your remaining credits and will carry these forward to your next log-on session.

If, after conducting a search you are presented with a large number of results, there is a ‘Filter’ field specifically for the results that were produced which will allow you to narrow down those results by postcode or address, for example.  This will assist the accuracy of searching without requiring additional payment.

Building Notices PDF Form

Building Notice - This form of application is more suited to small basic schemes where the applicant and builder are fully conversant with the applicable Building Regulations requirements. To lodge the application you only need to submit the application form, the appropriate fee and in some cases a site location plan. Whilst a convenient and fast method of application it has the disadvantage that we do not formally check plans and specifications for compliance in advance of the work being carried out. Consequently there is a risk that we will only discover non-compliant work when we carry out our site inspections and this can necessitate expensive remedial works.

In some cases our Surveyors will need to ask for plans, specifications and structural calculations to provide a record of the construction and demonstrate compliance while the work is being carried out.

A Full Plans application avoids this risk giving you a reassurance that you can safely build in accordance with a checked and approved design

Full Plans Application / Submission PDF Form

Full Plans Application / Submission - With a Full Plans application you need to submit detailed drawings, specifications and (in some cases) structural design calculations with your application form and fee payment. We check these for compliance and contact you if we need any amendments or further information before issuing an approval.

You can confidently build to approved details in the knowledge that the work should be approved by our inspecting Surveyors unless there are previously unknown factors that come to light during the project.

Regularisation PDF Form

Regularisation - This is the method of applying for retrospective approval for work that has been carried out without Building Regulations approval. To be acceptable the applicant needs to include drawings (plans sections and elevations) and detailed specifications for the building work with the completed form and appropriate fee. This needs to, as far as possible, demonstrate that the work complies with the appropriate building regulations.

We recognise that some elements of the construction may be hidden from view so it is not possible to provide detailed information. On receipt of the application a Surveyor will check the information and arrange to visit the property. In many cases they will need to ask the applicant to expose part of the structure in order to satisfy themselves that it meets the minimum standards.

If we can establish that the work is compliant then we will issue a Regularisation Certificate to confirm that having taken reasonable steps to assess the work it appears to accord with the Building Regulations.       

Demolition of Buildings - To notify us of a demolition, please email the following details to

  • Full location of demolition site with site plan
  • Contact details of person submitting the application (including email address)
  • Person responsible for carrying out the demolition work
  • Proposed start date
  • Estimated duration of work

Note: a fee of £250.00 is applicable - Please confirm in your email who we should contact to collect this fee.

We don't want things to go wrong, but if they do and we can't rectify matters then please see the following appeal guide. The guide is intended for anyone proposing to carry out building work - including building/land owners, builders and professional advisers who may be acting as an agent - who is seeking to ensure that their work complies with the Building Regulations but where agreement cannot be reached with the building control body, i.e. a local authority or a private sector approved inspector (as applicable)
