Frequently Asked Questions

What does the fixed price repair cover?

Our engineer will visit your home and repair your boiler and will replace all parts required to solve the problem. So no matter how many new parts are used you will pay a fixed price. The only parts we cannot cover are the main heat exchanger and expansion vessel.

Can you fix any Vaillant boiler?

We will be able to repair any Vaillant boiler unless it is uneconomic to do so. In which case we will provide advice on a suitable product to replace the boiler. Our fixed price repair offer does not cover our larger commercial range of boilers - Vaillant ecoTEC 45kw to 120 kw models.

What guarantee will I receive for the repair?

We use genuine Vaillant spare parts for the repair. In fact our engineers carry over 600 parts on their vans to ensure that we can offer a fantastic 95% first time fix rate. All parts fitted are guaranteed for 12 months. Our labour is also guaranteed for 90 days.

Will it be fixed the same day?

We have over 250 Vaillant engineers across the UK – the largest of any UK heating manufacturers. All are experts in our products, Gas Safe Registered and they carry large stocks of genuine Vaillant spare parts – which means we can achieve a 95% first time fix rate.

If it’s a part they don’t have with them, we can order the part for a next day delivery (excluding Sundays) and our engineer will be booked to return and finish the repair.

What happens if you cannot repair my boiler?

If it’s too old to repair then our engineer will advise you straight away on the options to replace with a suitable new Vaillant boiler.
