Builder in Portsmouth (104)

Here are some steps to make sure you're hiring someone reliable:

• Start with reviews. Look for builders in Portsmouth with verified Checkatrade reviews. You'll see feedback on timekeeping, communication, tidiness and overall workmanship – our top-rated builders average over 9/10 in each of these areas.
• Check their profile. All Checkatrade builders have passed up to 12 checks, including proof of Public Liability Insurance, identity checks and qualifications where relevant.
• Speak to them directly. Once you've shortlisted a few builders near you, arrange a phone call or meeting. Ask about their experience, similar jobs they've completed, and availability.
• Ask for references. Good builders will be happy to put you in touch with previous customers.
• Get quotes. Always get at least three written quotes and compare what's included. The cheapest option isn’t always the best – look at value, not just cost.

Using Checkatrade takes a lot of the guesswork out. All builders listed have been checked, and you can see exactly what past customers thought of their work.

How much is an acceptable amount to pay a builder upfront before they start any building work for you?

Good question. It’s not uncommon for a builder to ask for a small payment upfront to confirm the project, though it will depend on the size of the project and the individual builder.

That initial payment will confirm your slot for the building work, but it's often a payment for materials for the job too.

For small jobs, you might not need to pay anything upfront. For larger projects, most builders will request a deposit – typically around 10% to cover materials. Either way, it's best to discuss this with them directly and have in writing what was agreed for that initial payment.

When looking for a builder, one of the topics you should discuss before hiring anyone is the project’s payment terms. These terms should clearly state the different stages of the building work, with details of what work will be completed and the amount of payment that will be expected at each stage.

It’s also a good idea to have a project contract signed by both you and the builder at the beginning of the job, stating what exactly is included and what isn’t.

Here’s what to agree upfront:

• Payment schedule linked to stages of the work
• What’s included in each phase
• When final payment is due

Avoid paying full amounts in advance. Make sure any upfront payments are backed up with a signed contract and a receipt.

How to pay a builder

When it comes to paying your builder, you want everything to be clear from the start so that both parties are on the same page about how much will be paid, when and how.

1. Draw up a contract with details of the project and make sure both parties sign it before any work begins

2. Pay contractors on time after you’ve inspected their work to make sure you’re happy and it’s in line with expectations

3. Avoid paying cash, you will want to have clear evidence of payments when they're made. You'll want to make sure you're given an invoice or receipt for the full amount you’ve paid so that you have records

Top tip – Always budget for extras. The vast majority of building work will run into snags, swaps or expansions to the scope of the project, so it’s a good move to budget for 10-20% as a contingency for such an outcome. It’s better to be over prepared and have cash left over at the end of the project than it is to get stuck without funds halfway through.

There are various types of insurance that your build might have, but there are two that will most concern you as their customer.

You should make sure that any builder you hire has the following insurance:

• Public Liability Insurance – This policy protects builders against legal costs if a member of the public is injured due to their work
• Employers' Liability Insurance – If your builder employs workers, they must have employers' liability insurance to cover any injuries sustained by employees, including full-time staff and short-term subcontractors

In addition to the above, builders working locally in Portsmouth may choose to invest in other insurance, such as tools insurance or personal accident insurance.

Not all builders require formal qualifications, but many do hold trade-specific accreditations or training. It's a good idea to check your builder's accreditations before booking.

Some key qualifications to look out for when hiring a builder include:

• A Construction NVQ
• CSCS cards
• Memberships to professional bodies like the FMB

Look beyond the bottom line. When comparing quotes, make sure you check:

1. What’s included (materials, labour, equipment hire)
2. Whether VAT is included
3. Payment terms (e.g. deposit and staged payments)
4. Estimated timeframes
5. Insurance or warranties offered

It’s also worth checking how quickly they respond, how clearly they explain things, and how confident they seem. This can help you feel more secure in your decision.

Builders handle a wide range of construction work, including:

• New builds
• Renovations
• Extensions
• Structural repairs
• Internal remodelling

They often work with other tradespeople like electricians and plumbers.
