Home repairs and improvements

Home improvements can transform and add value to your home but it is easy for costs to escalate and projects to go wrong. The Homeowners Alliance step-by-step guide can help you do home improvements and repairs the right way.

Before work starts

• Don’t forget to contact your Local Authority Planning and Building Control Departments if you are doing significant works.  Read more about whether or not you need planning permission.
• If you are doing a project which impacts adjoining or shared walls with your neighbours you may need to issue a

  Party Wall Notice. See our advice guide Do I need a Party Wall Agreement?

• If you are doing a project which makes significant structural changes you may need the help of a structural engineer to enable you to obtain Building Control Approval. See our guide Do I need a Structural Engineer?
• If your home is listed or you live in a Conservation Area, check with your Local Authority for any restrictions on what changes you can make.
• Consider whether your building projects will add value to your home.  A local estate agent can help you assess whether you will see a return on your investment if that is important for you.
• Once you are ready to commence, it is a good idea to inform your home insurance provider that you are undertaking building works to ensure your cover is not affected.  There can be a higher risk of potential damage if you’re removing walls or opening up the roof as may be the case if you are extending or doing a loft conversion.

Budgeting, quotes and specifications

• Make a detailed list of everything you would like to have included, this will help when you ask for quotations.
• Compare quotes item by item and not just by the overall cost of the job.
• Check that VAT is included in the costs you are quoted.
• Set aside some money for unexpected problems – rule of thumb is 10% of total cost.
• If you are thinking about taking out a loan or using another form of credit to pay for the work, consider the full cost of the credit including the interest.  Read our guide on how to finance your home improvement project.  It may also be a good time to consider remortgaging as a way of freeing up funds.
• Include costs for labour and parts in your overall budget.
• When purchasing items, shop around and check online.
• Agree who will purchase items and be responsible for making sure they arrive on time.
• Clarify at the start what marks the end of the project and make a note of this.
• Read our guide to house renovation costs for an idea of what projects may cost.

Finding a trader

• Carry out checks to find a good trader – this will stop most problems straight away. Take a look at how to find the best tradesman for the job.
• Find your tradesman by using our Find a Tradesman search tool. Or ask friends, family or neighbours who have undertaken similar works for recommendations.
• Check online for websites with a feedback option to rate traders, but be wary of relying completely on the reports. Our guide outlines how the online tradesman review sites work and what to watch for.
• If you are doing major structural works and your builder requires technical drawings, you can get quotes from Structural Engineers here.
• Be clear about whether you need building regulations certificates for any of the work you are doing, for example electrical, windows and water.
• Be prepared, look for a trader well in advance of when you would like the project to start.
• Be careful about using anyone who comes to your door cold calling.
