Get more than one quote
Ask two or three local businesses to look at the job and give you a written quote. A quote is a fixed price for the work described; an estimate is a best guess that can change. Make sure each one covers the same work, so you are comparing like with like.
Check the registrations that matter
Some work legally needs a registered tradesperson. Others are optional schemes that vet their members.
- Gas: anyone working on gas appliances must be on the Gas Safe Register. Check their ID card at gassaferegister.co.uk.
- Electrics: notifiable electrical work in England and Wales should be done by an electrician registered with a competent person scheme such as NICEIC, NAPIT or ELECSA, so it can be self-certified under Part P of the Building Regulations.
- Windows and doors: installers registered with FENSA or Certass can self-certify replacement windows and doors.
- Optional schemes such as TrustMark vet businesses for technical skill, customer service and trading practices.
Planning and Building Regulations
Extensions, structural changes, new windows, rewiring and some drainage work need Building Regulations approval. Bigger projects may also need planning permission. Agree in writing who will apply for approvals and get the completion certificates.
Put it in writing
A short written contract avoids most disputes. It should set out the work, the price, the start and finish dates, what happens if things change, and how you will pay.
Paying safely
Avoid paying large sums up front. For bigger jobs, agree stage payments tied to finished work. Paying by credit card for items over £100 can give you extra protection under section 75 of the Consumer Credit Act.
Your rights
Under the Consumer Rights Act 2015, a service must be carried out with reasonable care and skill, within a reasonable time and at a reasonable price if none was agreed. If something goes wrong, raise it with the business first, in writing.
Be wary of cold callers
Be cautious if someone knocks on your door saying they have noticed a problem with your roof or driveway, or offers a discount for paying in cash today. Take their details and check them before agreeing to anything.
