Boiler repair Excellent and reliable company. All engineers knowledgeable, friendly and smartly dressed. Replaced expansion vessel and pressure valve switch. Everything was clearly explained and all queries explained. Kate was very helpful when calling for help and to book up the repair. A pleasure to use a trustworthy business. This was shortly following using a 24 hour ‘Check a trade’ Company for a repair who disappointedly were untrustworthy. I have learnt a valuable lesson and would recommend fellow customers to use Bespoke Gas. Thank you to the Botley Team.

Bespoke are a very efficient and helpful company. They installed our gas boiler and have just completed its first service.

Heartily recommended!! Right from the initial contact with their office, I've been impressed with the way everyone at Bespoke Gas goes about their business. Their pricing is clear and transparent, their enthusiasm for what they do is evident, and their customer service is superb! Great team who can now count me as a definite return client.
These guys are the business! Really professional, highly competent, and thoughtful ( not just in being around the house but also in the way they do the installation). I've rarely come across a team like this where they are all such lovely people, considerate, tidy, prompt, and generally hugely confidence inspiring. So glad we used them as are the two other householders in our road who recommended them to us.
Excellent service from Bespoke Gas as usual. Faultless.
A great company… A really friendly and knowledgeable team. Really responsive to questions. They went through all my options for replacing the boiler and removing the old system. Their work was great, neat and tidy and you couldn’t tell you’d had workmen in by the end of each day. Highly recommend.

Going the extra mile From the initial survey, the important thing for ourselves was to have the install exact. In our case we wanted all the boiler pipes hidden in the kitchen and a high finish outside on the brickwork on top of the other work. The team achieved this and being able to work to this standard in a heatwave was going some.

Pressure reducing valve fitted We had a pressure reducing valve installed and it was quick and caused minimal disruption. Another service provided by Bespoke Gas that we are really happy with.
